Definitions

• TAILGATING PREVENTION APPARATUS Summary of invention The primary objective of this instant invention is to provision a motor vehicle with motion detecting (transceiver) type apparatus, such as: Radar, Photoelectric, Ultrasonic, Passive Infrared, or Microwave, etc.
• motion detecting (transceiver) type apparatus such as: Radar, Photoelectric, Ultrasonic, Passive Infrared, or Microwave, etc.
• a switch-means located within the said motion detecting device which will instantly dis ⁇ charge a signal to detect any other vehicle directly within its path and/or, range -- and, simultaneously emit a warning signal to the operator of said vehicle, in the event that he is too close and traveling too fast to stop should an unexpect ⁇ ed emergency arise.
• Another object of said invention is to provision a vehi ⁇ cle with speed calculating apparatus (i.e., speedometer) which is calibrated to operate in conjunction with the range and sensitivity controls of a motion detecting apparatus — so that, whenever the operator of a vehicle (so provisioned) moves within a predetermined and designated 'danger-zone' behind a preceeding vehicle, sai'd operator will be given a warning signal;
• Said speed calculating apparatus and the range control of the motion detecting device is to be so calibrated that movement of the speed-indicator (i.e., speedometer needle) will, both: I.- automatically energize (i.e., switch-on) the said motion detecting apparatus whenever a certain speed is
• Still yet another object of said invention is to cali ⁇ brate the above described apparatus, so that: both the Sensi ⁇ tivity and Range controls are locked-in (according to pre ⁇ scribed Department of Motor Vehicles' safety Speed and Range standard specifications)— so as to give a warning signal alerting the operator of a moving vehicle, whenever said operator might occasionally and/or, accidently exceed the pre ⁇ determined safety margin as established by said D.M.V. , supra...
• An additional object of said invention is to provide a (mechanically-operated) speedometer, connected by means of a flexible drive cable from the gearbox tail shaft of the transmission(or such other suitable location), provisioned with a variable resistor means — so that said speedometer will function and operate in similar fashion to a rheostat or potentiometer; And, to connect said speedometer in parallel with the Range and/or. Sensitivity Controls of a motion de ⁇ tecting apparatus; So that. Movement of the vehicle at speeds in excess of 35 m.p.h. provide mechanical displacement which, in turn, activates a potentiometer device by means of a cable attached to the transmission (built within a speedometer) which then converts said displacement into an electrical signal. This signal is then transmitted by wire to the transducers located within the transceiver and adjusts the range of de ⁇ tection according to the rate of speed at which said vehicle is traveling.
• a further objective of said invention is to connect such motion detecting (transceiver) apparatus to the vehicle's power source; and, to provision such device with a warning 'Buzzer' or other signalling means.
• a further object of said invention is to, provision all new vehicles with this safe-guard apparatus, before said vehicles leave the factory; And/or, provision vehicles present ⁇ ly in service with this said safe-guard device by means of either replacing their speedometers or by adding an additional speedometer — and, to calibrate said replacement or additional speedometer by fully magnetizing the magnets therein and then demagnetizing them until the desired readings and/or ratios have been obtained.
• SUBSTITUTE SHEET ' of said transmitter-receiver, supervisory circuitry and power supply fit into one small 3 3/4 X 4 inch space.
• the unit also contains a pulse-modulated solid-state light source whose life rating is in excess of 25 years; It has an adjustable range from 3 to 75 feet; And, the beam may be aimed at a bounce- back reflector.
• Said unit is therefore capable of reaching out with an invisible beam so as to detect the presence of any vehicle within its path and range; Simply by aiming the beam at a bounce-back reflector — since said reflector, without any adjustment of any kind, bounces the invisible beam from the transmitter back to the receiver...
• Fig. 1 illustrates a procession of four (4) vehicles (A-I, A-2, A-3, and A-4) travelling along a length of highway at varied distances apart.
• A-5 represents the beam or waves which may be emitted from the antenna of a motion detecting (transceiver) apparatus (such as: Radar, Photoelectric, Ultra ⁇ sonic, Infrared or Microwave, etc.), which might be located within the front section of an automobile.
• a motion detecting (transceiver) apparatus such as: Radar, Photoelectric, Ultra ⁇ sonic, Infrared or Microwave, etc.
• Fig. 2 shows a specially designed and constructed speedo ⁇ meter, provisioned with a strip of electric conducting material B-I — secured to a portion of the face of said speedometer by non-electric conducting means;
• B-2 shows an electric conducting lead B-3 connected at said junction B-2;
• B-4 represents a speed indicator needle (or finger) provisioned with a small nipple-contact (B-5) secured to the underside thereof, further connected by (insulated) electric conducting means (B-6) to lead B-7...
• Fig. 3 illustrates (generally) amotion detecting (trans ⁇ ceiver apparatus provisioned with an alarm (Buzzer) signalling means C-I (further marked with a large letter 'B'); Buzzer ('B') C-I is further shown connected by two (2) leads C-2 and C-3 to terminal (junction) points 4 and 5 — located within said motion detecting (transceiver) apparatus; Terminal point #5, here, represents 'Relay, Common 1 ; And, whereas, terminal point #4 represents 'Relay, Normall-open' . Terminal points #1 and #2 are connected directly to the primary (vehicle)

• Fig. 4 illustrates an enlarged view of the manually operated Range ('R') control means C-5 shown in 'Fig. 3'; and, shows the manner in which leads C-6 and C-7 may be con ⁇ nected in parallel with the said Range ('R') control apparatus #C-5 — so that, even when said control C-5 may be manually switched-off, the input to the integrator and range control portion of the motion detecting (transceiver) apparatus may still be transmitted by means of the said parallel connecting leads #C-6 and C-7...
• a significant feature is that the device is designed to operate automatically — so that, while the motion detecting (trans ⁇ ceiver) device would normally remain dormant during normal City use; Still, as soon as the predetermined (danger) speed
• the speedometer will automatically switch-on the motion detecting device which has been pre-set to detect any other vehicle within its path
