Abstract

The method is for screening against theft of mobile objects carried loosely on the body and involves a mother mini-radio carried on the body, preferably in a belt. The mother mini-radio is in connection with a daughter mini-radio fitted in a hand-bag or similar. The two radios exchange signals. The effective range is adjustable of both radios, i.e. the signal is relative strong where the range is less than 2 metres, between 2 and 4 metres it is relatively weak and above 5 metres is very weak. The mother radio transmits periodically during a short period and activates a return signal in the daughter radio. The mother radio measures the strength of the return signal and draws the conclusion that nothing is happening. When the distance is greater and the return signal is relatively weak an alarm is sounded in the mother radio and the person involved is given the requisite attention.

Description

Virtual "chain with alarm padlock"

The virtual "chain with alarm padlock" aims to provide protection against theft of mobile goods that are carried independently of the body.

5 For example, a briefcase with valuable documents, a bag with a laptop, but also a ladies' bag with money or a shopping bag. Expensive clothing can also be considered, for example a leather jacket, etc. Furthermore, it is possible to monitor the distance of small children from their parents. When in the remainder of this description reference is made to a suitcase, all these 10 other possibilities are also meant

Invisible in an inner pocket or sewn into clothing, worn on the body with a hanging strap or built into a belt, a small radio is mounted, the so-called "mother radio" that can both send and receive. Preferably, the so-called Blue Tooth method is used. Other forms of sender / receiver are not excluded.

In the case is the "daughter radio", which, like the "mother radio", can send and receive. The parent radio broadcasts a pulse periodically (for example, every 2 seconds) for a short time, (for example, a thousandth of a second) to the daughter radio. If the distance between the mother radio and the daughter radio is less than, for example, 2 m, the daughter sends a relatively strong signal back to the mother. This strong signal means: Nothing wrong. There is a control mechanism on the parent radio to set the response distance.

However, when the distance between mother and daughter increases, for example at about 4 m, a soft signal in the mother radio will initially alert the person to the fact that the distance becomes greater. Action can now be taken by switching off the further alarm. For example, when people have to leave the workplace at the office to get coffee. As an option, a facility can be built in that the case is automatically locked when the distance to the parent radio becomes greater than the touch distance.

If the person wearing the mother radio does not respond to the soft signal, it may be assumed that the suitcase with the daughter radio is undesirably removed, for example due to theft on the train. There is now a sharp alarm that scares the thief on his or her body. Because the suitcase is automatically locked and the alarm can only be switched off by the owner, the thief will throw the suitcase away and get rid of himself. The owner can now easily find the case and then switch off the alarm.

A mother radio can be combined with several daughter radios.

5 Described above are separate mother and daughter radios. It is conceivable that existing equipment already has a Blue Tooth chip or other radio communication built in, for example in a laptop and that a mother radio and a separate program in the aforementioned laptop will suffice. It is also possible to program described functionality in, for example, a mobile telephone to be worn on the body and the related equipment, for example a laptop. It is also possible to use the mobile phone and a separate daughter radio in the bag, suitcase or other valuable object to be monitored. It is also possible to use programming in the mobile phone and the handheld computer (Type Palm). Telephone signal (possibly extra sharp and loud) 15 goes if the distance between the two becomes too large.

As a variant of the above, this facility can be built into car keys; when the car keys are a certain distance away from the car, it is automatically locked. Furthermore, it is possible to carry said mother radio and when the keys are a certain distance away from the carrier, the car cannot be opened and the engine is blocked. In other words, if the keys are stolen, the thief cannot enter the car; even if he breaks it open, the car cannot be started.

Claims (11)

1. A mini radio worn on or on the body [mother radio], is connected to another mini radio [daughter radio] mounted in a bag, suitcase or other valuable object to be monitored, characterized in that these two radio signals exchange each other. 2. The operating range of the communication distance is adjustable from the parent radio or from the daughter radio. The characteristic of the distance setting is as follows: position 1: eg smaller than 2m distance: relatively strong signal, position 2: eg from 2 to 4 m: relatively weak signal position 3: eg after 5 m relatively very weak signal 3. A characteristic of the relatively strong signal is that the object to be monitored is within reach of the person. The mother radio broadcasts periodically for a short time and activates a return signal in the daughter radio. The mother radio measures the strength of the return signal and draws the conclusion: Nothing wrong. 4. When the distance increases and as a result a relatively weak return signal is received, a warning alarm occurs in the parent radio. The person is alerted to this by means of a soft alarm or a vibrating function that increases the distance to the suitcase. 5. Subject to the aforementioned warning function to the person, the daughter radio can be programmed in such a way that due to the weakness of the signal received, the suitcase is automatically locked by means of a scaling function. 6. The function described in 5 can also be applied to a car: if the car keys are too far away from the owner, not only will the alarm go off, but the car will also be slated and the engine locked. 7. With the relatively weak signal described under 4 and 5, the person can intervene at the mother radio by turning off the case when example 30 leaves the suitcase of his own will. Suitcase can remain locked. When the case is turned off, the person can continue his way from the suitcase without triggering the big alarm in the suitcase ((see 7) 8. With a very weak signal received, a large alarm goes off in the case. f019218 » 9. The described functionality, described above with separate mother and daughter radios, can also be obtained directly with apart hours that already include BlueTooth, for example. In that case it is only necessary to load additional software. 10. Methods of distance determination as described above in points 2, 3 and 4 can also be carried out in a different way while maintaining the same functionalities. A time clock can be installed in both the mother and daughter radio. The transmitted pulse is provided with a time code. The distance 10 is calculated according to the time it takes for the pulse to reach the other radio. 11. When storing or delivering valuables in a wardrobe, for example, a motion sensor can be activated via the mother radio in the daughter radio. Once the case has been put away, it may no longer move. If this does happen, this is undesirable and an alarm is triggered. If, for example, the case comes to a standstill within 15 seconds, then there is nothing wrong. It may then be assumed that the suitcase has been moved without an angry design. In this case only a small signal sounds. However, if he continues to move for longer than the set time, then there is an angry setup and the big alarm goes off. 20 1019218 ·
