Description

TECHNICAL FIELD The invention relates to a method and navigation unit associated with a vehicle. More particularly, the invention provides a route planning mechanism for the vehicle.

BACKGROUND When planning a route, a vehicle, as well as when driving and navigating the vehicle, the driver may have access to a navigation system. Before a vehicle journey is started with the vehicle, a route to the final destination of the journey can be entered into the navigation system. The driver then only has to follow the Koran instructions given by the navigation system when cornering, which reduces problems with incorrect navigation.

Vehicles in this context refer to, for example, truck, truck, flatbed truck, transport vehicle, truck, motorhome, pickup, work car, passenger car, emergency vehicle, vehicle, van, quad bike, forwarder, excavator, car, car, crane truck, tanker truck, motorcycle, wheel loader, moped , scooter, limousine, sports car, race car, radio car, lawn mower, tank, snowmobile, snowmobile, SUV, crawler, tractor, go-kart, bus, combine harvester, agricultural machine, amphibious vehicle, bat, ferry, cruise ship, ubat, aircraft, helicopter or other similar motto manned or unmanned means of transport, adapted for land, sea, or air-based geographical movement.

When driving some of these vehicles, there are regulations in the form of a maximum allowable driving time since the previous choir break, the number of daily rests per day and the like. These regulations can be different in different land regions, and also vary for different types of vehicles. An example of such a regulated short time is that the driver is allowed to Ora for four hours and 30 minutes and then must take a 45-minute break. 1 537 9 Della meant that the driver, as the maximum permitted short time has been reached since the previous choir interruption, is forced to stop for rest / rest during the prescribed period.

The short time is often monitored by a tachograph. This can continuously record speed as well as Icor and rest times. Some tachographs include a computer memory in the tachograph together with a driver card in the form of a smart card. Della is sometimes called a digital tachograph.

Violation of a regulated short term is punishable and can result in fines for the driver. Furthermore, the authorities have the power to inspect the vehicle printer and can demand! Dots afterwards, if it turns out that all the regulations have been violated by the driver in some respect. 10 Della can lead to all The goods are forced to panic through all stop the vehicle for example at a parking pocket along the road when the allowed short time ticked out, for all avoid! Doter; only for a short while later when the journey has resumed, perhaps stop again for refueling or have lunch when a petrol station or restaurant is passed.

In addition to the loss of time that occurs, and the potentially stimulating rest million that the driver is exposed to during a panic break, this can lead to safety risks, as for example a parked truck along the road can obscure the view of other road users, or cause an accident when driving into or driving out of the car. .

If the Waren for all avoid this safety stops at a restaurant after, for example, three hours and a quarter 'corning since the previous chorus break, the above-described situation with panic break is avoided, but this instead leads to an underutilization of the vehicle in relation to the available short time, which can become costly and lead to delayed delivery.

Another problem for Waren is that during the voyage, various types of unforeseen actions can occur along the predetermined route, such as a traffic accident, authority control, cow formation, slippery road conditions, poor visibility, etc., which makes all the original planning of the voyage no longer possible. stems or ar appropriate. 2 537 9 It can be stated that much remains of all Ora to facilitate a vehicle's route planning.

SUMMARY It is therefore an object of this invention to make it possible to plan a route for a vehicle, to solve at least some of the above problems and to achieve a vehicle improvement. Della grille, perhaps especially when the route runs for several days so that the driver can make the most of his short times and arrive armed as early as possible. According to a first aspect of the invention, this targeting is achieved by a method for planning the route of a vehicle. The method comprises receiving the remaining short time to the subsequent chorus interruption for the Good, from a short time calculating unit in the vehicle. Furthermore, the method comprises establishing a route, which enables the final destination of the vehicle to be reached in the received remaining short time. In case this is not possible, the procedure comprises that a route including at least one planned crossing point along the route is determined, the crossing point being located so that all the final destination is reached in as short a time as possible. The fixed route is then presented to the driver of the vehicle. Furthermore, the procedure includes all the number of goods in the vehicle is determined, and since the determined number of drivers in the vehicle is more than one, the determination of the route and any chopping break where driver change is possible, all final destinations are made in as short a time as possible.

According to a second aspect of the invention, this targeting is achieved by a navigation unit for planning the route of a vehicle. The navigation unit comprises a receiver, arranged to receive information regarding the remaining short time to the subsequent chorus interruption far Waren, from a short time calculating unit in the vehicle. Furthermore, the navigation unit comprises a processor circuit, arranged to determine all the route, which enables the final destination of the vehicle to be reached in the remaining short time, or, if this is not possible, to determine a route comprising at least one planned chorus break along the route, so located at the end. as short a time as possible. The navigation unit also comprises, or can be connected to a presentation unit, arranged to present the determined route. Furthermore, the processor circuit is arranged to determine the number of drivers in the vehicle and, as the number of drivers in the vehicle is more than one, to determine the route and any chopping break where change of driver is possible, so that the final destination is reached in as short a time as possible.

By giving the navigation unit access to information about the driver's short times, and calculating, for example, time left for a break in the form of a break or rest, the navigation unit can calculate if the vehicle can reach the final destination of the vehicle before the permitted short time ends, or if a break breaks maste tas. Furthermore, a new route with possible chorus interruptions can be calculated, if necessary as a result of, for example, a traffic restriction on the route and / or the vehicle. Through the navigation unit can calculate how long the driver's lane has time to work during the remaining short time to break, so that the driver's maximum permitted short time is used, the driver's planning of his route can be improved so that the final destination is faster, panic stops with the vehicle can be avoided and statutory breaks can be avoided. the permitted short time is utilized in an optimal, or at least improved way. This achieves an improvement of the vehicle.

Other advantages and further features will become apparent from the following detailed description of the invention.

DETAILED DESCRIPTION OF THE INVENTION The invention is defined as a method and a navigation unit for planning a route for a vehicle, which can be realized in any of the embodiments described below. However, this invention may be embodied in many different forms and should not be construed as limited by the embodiments described, which are instead intended to illustrate and illustrate various aspects of the invention.

Additional aspects and features of the invention may become apparent from the following detailed description when considered in conjunction with the accompanying figures. However, the figures are only to be considered as examples of different embodiments of the invention and should not be construed as limiting the invention, which is limited only by the appended claims. Furthermore, the figures are not necessarily to scale, and are, unless otherwise specifically indicated, intended to conceptually illustrate aspects of the invention.

Figure 1A shows a vehicle 100, arranged for a method according to the invention. Inside the vehicle 100, for example in the cab, a short-term calculation unit 1 and a navigation unit 1 can be found. The short-term calculating unit 110 may, for example, be a tachograph. According to certain embodiments, the navigation unit 120 can be fixedly mounted in the vehicle 100, or be movable and mountable in the vehicle 100, for example in the driver's cab. The navigation unit 120 may also be a barbarian unit. Such a barbarian device can be constituted, for example, by the driver's mobile phone, computer, tablet or similar barbaric device according to certain embodiments.

Figure 1B shows an example of the driver environment in the vehicle 100. In the vehicle 100 is the short-term calculation unit 110 and the navigation unit 120, which comprises or is connected to a presentation unit 130. Such a presentation unit 130 can be constituted by, for example, a monitor, a monitor, a sound-generating unit comprising loudspeakers, a pressure-sensitive screen called a "touch screen" or the like. It may also include a combination of these. The navigation unit 120 may also in some embodiments comprise, or be connected to, an input unit 135. Such an input unit 135 may, in addition to a pressure-sensitive screen previously mentioned, be constituted by, for example, a keyboard, a keypad, a pointing device or similar device.

The short-term computing unit 110 and the navigation unit 120 are arranged to communicate with each other; at least the navigation unit 120 is arranged to receive a signal representing information from the short-term calculating unit 110. This information may include, for example, how long the driver maps since the previous chorus interruption, and / or how long the driver has time for subsequent chorus interruptions. The information may also include, for example, how many drivers are in the vehicle 100, or rather how many drivers' cards are loaded in the short-term recording unit 110, that is to say the tachograph in certain forms of performance. Based on this information, the navigation unit 120 can determine a route, or location for interruptions along the route, that is possible for the vehicle 100 to reach in the estimated remaining short time. As a result, a choir break can be planned as long as it corresponds to the driver's short times and choir breaks, such as break, break, rest, daily rest, weekly rest or the like. 6 537 9 As a result, a choir break can be planned so that it corresponds to the driver's short times and breaks according to government requirements, industry requirements and / or employer policy or the like.

Interruption in this context means, for example, a break or break of, for example, 45 minutes, followed by the vehicle 100 short of the same driver for a certain period of time, for example four hours and 30 minutes. By chopping break can also be meant resting as a result of all the driver mapping the vehicle 100 for a certain period of time a certain day, for example nine hours or a maximum of ten hours per day twice a week. By chorus interruption can also be meant weekly rest until 1614 by the driver mapping the vehicle 100 for a certain period of time during a week. However, the term chorus interruption may also mean that the driver is forced to interrupt the channeling of the vehicle during another time interval which may, for example, be implemented by the employer of, for example, safety shells, work environment shells or to give Waren an opportunity to smoke break, e.g. four hours and 30 minutes etc.

Furthermore, the term chorus interruption, perhaps in particular when the vehicle 100 has more than one driver, also includes a temporary stop with the vehicle 100 to make possible change of driver when the estimated short time of the respective ft: wares ends.

When the collision with the vehicle 100 is started, the driver must log in to the short-term calculation unit by inserting his driver card or the like into the short-term calculation unit 110, for example the tachograph, and armed start or continue the driver's log into the short-term calculation unit 110.

An advantage of allowing the navigation unit 120 to access the short-term calculation unit 110, and the information contained therein regarding the driver's short-term, is especially since the short-term calculation unit 110 consists of the vehicle's tachograph, thereby at least partially utilizing existing equipment in the vehicle 100. The invention is cheap and easy to implement, as tachographs, driver logs and driver cards must be present in vehicles 100 of a certain type. 7 537 9 In addition, the calculation of the driver's short time spent in the short time calculating unit 110, especially since it includes a tachograph, can be considered reliable, cla manipulation of this calculation is illegal, which probably discourages many from trying to influence or manipulate the calculation. of the short term.

The communication between the navigation unit 120 and the short-term calculation unit 110, as well as between the navigation unit 120 and, where applicable, with any presentation unit 130, input unit 135 and / or detectors / sensors in the vehicle 100 may be performed by a wired or wireless interface according to various embodiments.

Such wireless network may, for example, be based on the following technologies: Global System for Mobile Communications (GSM), Enhanced Data Rates for GSM Evolution (EDGE), Universal Mobile Telecommunications System (UMTS), Code Division Access (CDMA), (CDMA 2000 ), Time Division Synchronous CDMA (TD-SCDMA), Long Term Evolution (LTE); Wireless Fidelity (Wi-Fi), as defined by the Institute of Electrical and Electronics Engineers (IEEE) standards 802.11 a, ac, b, g and / or n, Internet Protocol (IP), Bluetooth and / or Near Field Communication, (NFC ), according to different embodiments.

The wired network may, for example, be based on the flag of the following technologies in the vehicle 100: Controller Area Network (CAN), Media Oriented Systems Transport (MOST), Ethernet. According to some embodiments, the wired interface may, for example, be based on the flag of the following technologies: Ethernet, Universal Serial Bus (USB), SerieII RS232, FireWire, Thunderbolt, to name just a few.

By allowing the navigation unit 120 to obtain information about the driver's remaining Maid from the short time calculating unit 110, i.e. the tachograph in certain embodiments, the navigation unit 120 can calculate an flight or update an existing route for the vehicle 100 which can be adapted to the driver's available short time. 8 537 9 Della takes place through all the navigation unit 120 receives information from the short-term calculation unit 110 about remaining short times and suggests one or more routes, if necessary with chorus interruptions, which are optimized or at least adapted to the remaining permitted short time according to the short-term calculation unit 110.

Furthermore, the navigation unit 120 may have access to information for planning a route for the vehicle 100, such as map data, previous destinations, attributes for different sections of the road such as, for example, bar grade, type of road, speed limit, etc .; Points of Interest (POIs), and / or vehicle information previously stored or configured by the driver of the vehicle, alternatively read by detectors / sensors such as vehicle weight, height, length, width, axle load, presence of packaged truck, dangerous goods, lost goods in the cargo space and the like.

This allows you to avoid wagons where certain vehicles 100 such as trucks and / or caravans are not allowed, narrow streets and repair bridges and tunnels. The points of interest, or POIs, may include, for example, gas stations, shops open on duty, lorries, or other places including those which the driver has entered into the navigation unit 120 for various reasons in previous cases.

When an unforeseen event occurs, such as limited passability along the route entered in the navigation unit 120, as a result of, for example, a traffic jam, cow formation or accident on this route, so that the planned route cannot be followed, the calculation can be reversed, based on the remaining short-term, so that a new alternative route can be determined.

The navigation unit 120 can access such information regarding accessibility disruption on the planned route, for example via a subscription service, a traffic news broadcast, an authority warning, a weather play service, or the like, via a wireless interface.

In some embodiments, the route can be selected, or the route can be adapted or optimized according to the number of drivers in the vehicle 100, and a choice can be made where chorus breaks such as breaks and stops for driver changes can be made at an appropriate place at a time so both short-term is used.

In this case, the view can be taken, so all a driver's rest time is relocated when a second driver drives the vehicle 100 according to certain embodiments, when planning the route.

An advantage of embodiments where the short-term calculating unit 110 is constituted by a tachograph is that the goods, or drivers, when the collision with the vehicle 100 is started, must insert their driver card (s) into the tachograph, and armed taborja or continue the driver's log in the tachograph; this is due to legal requirements.

An advantage of allowing the navigation unit 120 to have access to a short-term calculating unit 110 in the form of a tachograph, and the information contained in the tachograph regarding the short-term driver is all that thereby at least partially utilizes existing equipment in the vehicle 100, making the invention cheap and uncomplicated. aft implement, as tachograph, driver log and driver card spirit must be present in the vehicle 100.

In addition, the calculation of the driver's remaining short time made in the tachograph can be considered reliable, as manipulation of this calculation is illegal, which probably deters many from trying to influence or manipulate the calculation of the short time.

Figure 2 shows a schematic example of planning route 210, 2 for vehicle 100, visualized on a display unit 130, such as a display. The starting point 200 for the travel route 210, 220 can be marked on the display unit 130. Along the first travel route 210 is a first car break 2 and along the second travel route 220 is a second car break point 240. Behind these travel routes 210, 220 leads to the same destination 250.

In certain embodiments, a presentation may be made on the display unit 130 of the fixed route 210, 220. Thereby, this route 210, 2 537 9 may be proposed to the driver of the vehicle. He can thus select this, or one of these travel routes 210, 220 and enter the navigation unit 120.

The display unit 130 shows a comparison between two alternative routes 210, 220 between a certain starting point and destination. The driver may have compared, for example, estimated travel time, car distance and fuel consumption for the various alternative routes 210, 220 for the vehicle 100. These calculations may be based on the previously received information related to the vehicle 100 and map data, as well as the remaining short time to rest. In this way, certain carriages can also be avoided or deselected which are not permitted or suitable for certain traffic, for example due to dangerous loads on the vehicle 100 or vehicle height that exceeds the permitted value on a certain carriageway.

The presentation unit 130 can be constituted, for example, by a pressure-sensitive screen called a "touch screen" and can therefore also function as an input unit 135. Della is, however, only an example. According to other embodiments, the screen 1 and the input unit 135 are separate units, wherein the input unit 135 can be constituted by, for example, a keyboard, a keypad, a pointing device or the like on the north fling.

Figure 3 shows an example of how a route 210, 220 for a vehicle 100 can be planned in a navigation unit 120. The combined river and signaling diagram in Figure 3 illustrates an embodiment of a seven-step procedure for planning route 210, 220 for the vehicle. 100. It should be noted, however, that all some of the described steps 1-7 can be performed in a slightly different chronological order from what the number order suggests and all some of them can be performed in parallel with each other, according to different embodiments. Furthermore, not all of the described steps 1-7 necessarily occur in all embodiments.

In a first step, information may be sent from the short-time calculating unit 110 to the navigation unit 120. Such information may include, for example, feeding the feed and / or calculating the remaining short time to subsequent chorus interruptions for the driver, counted from previous chorus interruptions.

This can be accomplished by sending a query navigation unit 120 to the short-term calculating unit 110, for example continuously or with a certain periodicity, such as, for example, a quarter, a half-hour, a half-hour, every two hours, every three hours or other similar interval. In some embodiments, the short-term calculating unit 110 may be triggered to send such information regarding the remaining short-term of the Good, or at the request of the Good.

Since the short-term calculation unit 110 has access to legal requirements for a break for the Good, for example a 45-minute break after 4 hours and a 30-minute break, the navigation unit 120 can calculate the remaining short time for the next break. Della grids aven, and perhaps especially when the short time extends beyond the current day. It will then also be necessary to take into account night rest and weekly rest, etc.

Based on this received calculation, the navigation unit 120 can determine an optimal, or improved route 210, 220, with regard to the remaining driving time.

In this determination, or calculation, according to certain embodiments, first a longest remaining cross section or maximum point can first be determined, for example by estimating how far the vehicle 100 will come within the remaining short time based on expected vehicle speed and the remaining short time obtained from the short time calculating unit 110. In another example, the speed of the vehicle can be estimated during the forward crossover in the direction of travel of the vehicle and multiplied by the estimated remaining short time.

If all calculate how far the vehicle 100 will come during the remaining short time, for example more map attributes and vehicle attributes can also be used, such as for example truck restrictions, and / or vehicle configuration, according to certain embodiments. This calculation of how far the vehicle 100 will come during the remaining short time can also be dynamically gams and recalculated / updated as the remaining short time is shaved down. Thus, a more accurate prediction can be made of how far the vehicle 100 will come before the remaining short time for chorus interruption ends.

This estimated speed of the vehicle 100 can be estimated, partly based on the existing speed of the vehicle unloaded via the speed feeder or via GPS unloading, partly on information available regarding the front carriageway such as speed limitation, traffic formation, temporary traffic obstruction, slipping, road work, reduced visibility / fog, snow, traffic accident, etc. Such information may be collected in whole or in part, for example from an information database and / or a positioning system such as a Global Positioning System (GPS), 10 Gallileo Global Navigation Satellite System (GNSS) GLObalnaja NAvigatsionnaja Sputnikovaja Sistema (GLONASS) or similar , which makes it possible to determine the vehicle's existing position in the form of longitude, latitude and altitude. Furthermore, the carriageway's carriageway, topographical vessel conditions and the like can be determined, which can affect the calculation of the carriageway that has time to be felled during the remaining short time according to certain embodiments.

Thereafter, information related to the calculated route 210, 220 can be sent to and presented on the display unit 130. Thereby, this route 210, 220 is proposed to the driver, who can choose to join it, or one of these routes 210, 220.

The route 210, 220 chosen by the driver can then be loaded and stored in the navigation unit 120, for example by the item entering it in the navigation unit 120 via an input unit 135. The entered route 210, 220 selected by the driver can then be stored in a memory in the navigation unit. , and any planned vehicle stop, or breakage can be entered as a partial template.

Figure 4 illustrates an example of an embodiment of the invention. The flow chart in Figure 4 depicts a procedure 400 in a navigation unit 120 for planning route 210, 220 for a vehicle 100. certain embodiments, to a passability restriction of either the fixed route 210, 220 and / or the vehicle 100.

In order to be able to plan the route of travel for the vehicle 100 in a correct manner, the method 400 may comprise a number of steps 401-406. It should be noted, however, that some of the described steps 401-406 may be performed in a slightly different chronological order from what the numbering order suggests and that some of them may be performed in parallel with each other, according to different embodiments. Furthermore, some may only be performed in certain embodiments, such as, for example, step 402 and / or 406 and in some cases step 404. The method 400 includes the following steps: Step 401 100.

The short-term calculation unit 110 may be constituted by the vehicle tachograph, according to certain embodiments.

The receipt of information regarding the remaining short time from the short time calculating unit 110 can be done continuously, with a certain predetermined or configurable time interval and / or at the request of the navigation unit 120, according to different embodiments.

Furthermore, the reception of information from the short-term computing unit 110 may be via a wired or wireless interface previously discussed, in various embodiments.

Step 402 This process step may be included in some, but not necessarily all, embodiments of the invention. 14 537 9 Number of drivers in the vehicle 100 fixed. Such a determination can be made, for example, by the short-term calculating unit 110, which can assume the driver card which has been fed into the short-term calculating unit 110.

A difference in the process 400 when there are one or more drivers in the vehicle, such as for example two drivers, is aft cla there are two or more drivers in the vehicle 100, the drivers can take turns so all one first driver has a break while the other driver Icor and vice versa. In this case, the vehicle 100 can be moved further than the vehicle 100 only has one driver, since the vehicle 100 must then stand still at break. As the vehicle 100 is driven by two or more alternating drivers, there may rather be a chorus break in the form of a daily rest which becomes limiting when calculating how far the vehicle can travel during the remaining short time.

Step 403 A route 210, 220 is established, which enables all the final destination 2 of the vehicle to be opened within the received 401 remaining short time.

In some embodiments, when the determined number of drivers in the vehicle 100 is more than one, the determination of route 210, 220, so that the final destination 250 can be reached in as short a time as possible.

The determination of route 210, 220 may include obtaining and considering a traffic restriction of route 210, 220 and / or the vehicle 100.

In certain embodiments, a plurality of alternative routes 210, 220 may be established to thereby give the driver an opportunity to select routes between these proposed alternatives.

Step 404 537 9 This process step is included in some, but not necessarily all, embodiments where the final destination 250 of the vehicle cannot be reached during the remaining short time received 401 from the short time calculating unit 110.

A route 210, 220 comprising at least one planned lane departure point 230, 240 along the route 210, 220 is determined, the lane departure point 230, 240 being located so that the final destination 250 is reached in as short a time as possible. Della then the chorus break 230, 240 can be chosen so that the driver's remaining short time is used to the maximum before chorus breaks are made. The term choir break can include break, break, rest, day rest, weekly rest or the like. In certain embodiments, a plurality of alternative travel routes 210, 220 and / or cross-breakpoints 230, 240 may be established for later presentation of these to the driver of the vehicle, thereby making it possible to select one of these.

In certain embodiments, when the determined 402 number of drivers in the vehicle 100 is more than one, the determination of route 210, 220 including lane departure point 230, 240 can be made to make a change of valley, so that the final destination 250 is reached in as short a time as possible.

The determination of route 210, 220 may include obtaining and considering a traffic restriction of route 210, 220 and / or the vehicle 100.

Such access limitation on the route 210, 220 may include attributes 20 for different road sections such as barity classification, type of road, restrictions in permitted vehicle height, speed limitation, cow formation, temporary traffic obstruction, slipping, road work, reduced visibility / fog, twisting, traffic accident / or railway crossing, and the passability restriction of the vehicle 100 includes vehicle restrictions previously stored or configured by the vehicle driver, alternatively unloaded by detector / sensor as if the vehicle 100 has a connected slack or is fully loaded, vehicle weight, height, length, width, axle load, dangerous goods, lost goods in the cargo space, defective engine and the like according to different embodiments. 16 537 9 Furthermore, consideration of timetables for ferries can also be taken into account. It can be calculated, for example, if the driver and the vehicle 100 reach a certain ferry, or if it is faster to, for example, take a detour over a bridge, such as the Oresund Bridge.

Step 40 The determined 403, 404 route 210, 220 is presented to the driver of the vehicle.

In certain embodiments, a plurality of alternative routes 210, 220 may be presented to the driver, thereby providing the opportunity to select one of these.

Such a presentation can be made, for example, on a presentation unit 130, such as a monitor or the like, by the driver of the vehicle.

Step 406 This process step may be included in some, but not necessarily all, embodiments of the invention.

The presented route route 210, 220 can be stored in the navigation unit 120, for example in a data memory, as the driver selects this route 210, 220, whereby any planned chorus break location 230, 240 along the route 210, 220 is stored as a sub-template.

The system 500 includes a short time calculating unit 110, arranged to supply all remaining short time for subsequent chorus interruptions. Furthermore, the system 500 may comprise an input unit 135, arranged to receive a route selection of the driver of the vehicle and a presentation unit 130. All these units are arranged for communication over a wireless or wired interface with a navigation unit 120 for planning a route for a vehicle. 100. The navigation unit 120 may be included in, connectable to, or associated with the vehicle 100 according to various embodiments. This navigation unit 120 is further arranged to collect, compile and dispose of navigation information, according to certain embodiments. The navigation unit 120 is configured to perform at least some of the previously described method steps 401406, included in the description of the method 400 for route planning for a vehicle 100.

In order to be able to correctly plan the route of travel for the vehicle 100, the navigation unit 120 contains a number of components which are described in more detail in the following text. Some of the described units and / or components occur in some, but not necessarily all, embodiments. There may also be additional electronics in the navigation unit 120, which is not entirely useful for understanding method 400 according to method steps 401-406 described above. Such additional electronics have been omitted from Figure 5 for the sake of clarity so as not to unnecessarily defend the understanding of the invention.
