Description

The invention relates to signaling devices (signaling devices) for preventing the loss of wearable items, such as mobile phones, wallets, keys and other valuable things.

Known signaling devices for the loss of wearable items containing the alarm unit located at the owner with an electromagnetic oscillation receiver and an electromagnetic oscillation source mounted on the object, giving the owner a signal of loss when the received signal is weakened due to the distance of the source from the receiver to a distance exceeding a predetermined radius of action. Such, in particular, is a signaling device, in the signaling unit of which contains a transceiver antenna, a square-wave pulse generator, an amplifier, a detector, and a sound source, and a source of electromagnetic waves installed in a wearable object containing a capacitor [1].

The disadvantage of such a signaling device is that it operates at a distance of only a few millimeters from the wearable item, which means that it gives the owner false signals when the source and the receiver move apart not because of the loss of the item, but because the owner decided to use this item.

In this regard, signaling devices with a range of about 0.5 m are more perfect, in which measures are taken that are mandatory with such a radius, ensuring access secrecy, and, in particular, do not allow an attacker who is trying to steal an object with his own source of electromagnetic waves to neutralize the action of the signaling device. This is the closest to the invention a signal device for the loss of wearable items, containing an alarm unit located at the owner’s location with an electromagnetic oscillation receiver and mounted on at least one wearable object owned by the owner of an electromagnetic oscillation source with a receiver tuning frequency and energy that ensures their stable detection by a receiver in a radius not exceeding the specified distance from the source [2]. In this device, the primary source of electromagnetic waves is located in the alarm unit, equipped with a square-wave generator and a transceiver antenna, and the source of electromagnetic waves mounted on a wearable object is secondary (externally driven) and is made in the form of a resonant LC circuit tuned to the frequency of the signal unit .

The disadvantage of this signaling device is the limited functionality associated with the fact that it has only one in advance, and only during the manufacturing process, the programmable parameter is the individual tuning frequency. Given the fact that the LC circuit located on the wearable object, due to overall and price restrictions, is high-quality, and therefore narrow-band, it cannot be, it is difficult to assume that more than a dozen options can be obtained in the frequency band reserved for such purposes. And this means that when more than one owner is in range (for example, in public transport), it is highly likely that the signaling devices of each of them will lose their working capacity. As for the possibility of obtaining additional options useful to the owners (for example, protecting more than one object in such a way by giving the owner a signal indicating the type of the lost object), obviously, there can be no talk of them in the frequency division of the channels. In addition, the passive nature of the source of electromagnetic oscillations fixed on the subject requires radiation of a much higher power than that which could be limited if this source was implemented according to the active principle (with its own power supply). Hence - an increased level of interference to nearby electronic equipment, and, in terms of functionality - the inability to obtain a range of action more than 0.5 m that is appropriate in some cases.

The objective of the invention is to significantly expand the functionality of the signaling device for the loss of wearable items. The technical result achieved in connection with the solution of this problem consists in obtaining a new high-tech product improving the quality of life - personal office equipment - which should be in stable demand and in the near future has a chance to occupy no less solid place in the arsenal of a person living an active life than which currently occupies, for example, a mobile phone.

The task according to the invention is achieved by the fact that in the detector the loss of wearable items containing the alarm unit located at the owner with a receiver of electromagnetic oscillations and mounted on at least one owner-owned wearable object of electromagnetic waves with a tuning frequency of the receiver and energy, ensuring their stable detection by the receiver in a radius not exceeding a specified distance from the source, the source of electromagnetic waves is minutes provided with its own power source with miniature transmitter pulse code modulation, the programmable receiver together with the parameters comprising at least two of the list: a transmission period of the code sequences radio pulses, binary digit corresponding to the code sequence, the carrier frequency of the radio pulses and radiated power.

Thus, the transmitting part is excluded from the alarm unit, but each of the wearable items protected from loss is equipped with its own miniature programmable transmitter, made, for example, in the form of a key fob or sticky application. The use of pulse-code modulation with flexibly programmable parameters allows you to get all the functionality discussed above that the prototype lacks, the main one of which is to keep the device operational even when the owner is in a crowded crowd. This is achieved by individualizing the signaling device not only by the frequency channel, but also by choosing (for example, using a random number generator) a unique code sequence, which is the transmitter’s access key only to “its” signaling unit, provided that it works at the same frequency in the reception area a number of "alien" transmitters. Programming the transmitter by radiated power allows you to flexibly control the radius of action, by the period of transmission of code sequences - to save, if necessary, the resource of power supplies, etc. The number of programming parameters, depending on the model of the signaling device, characterized by the described essential feature, may be different.

It is advisable that the detector contains a signaling unit with a decoder of the received pulse sequences, the circuit of which allows to recognize both a common attribute of the owner and at least two private signs of different wearable items belonging to this owner. Thus, the functionality of protection against loss with the help of such a signaling device of more than one object is realized. Naturally, in this case, the signaling device must contain at least two sources installed on these items, programmed in the same way, with the exception of the item characteristic entered into the code sequence. It is advisable to program the receiver to give the owner a signal containing both general information about the fact of the loss of any of the wearable items when the owner’s sign disappears, and clarifying information about which of the items is lost.

Additional conveniences are created for the owner if the signaling unit contains two different types of devices for displaying this kind of general and clarifying information. A very convenient option is when the first device is a signal converter into a tactile form, made, for example, in the form of an owner of a bracelet periodically compressed on the hand, on which an alarm unit is fixed. In this case, the second device can be a signal converter into a visual form, highlighting the word corresponding to the lost object on the miniature alphanumeric display, which is equipped with an alarm unit.

Naturally, such a signaling device should contain an adapter for interfacing with a computer and a software component, allowing the owner to program the signaling unit and sources from an ordinary personal computer independently or in the service department regarding the parameters allowed for arbitrary change.

In order for the signaling device to be in demand among consumers with various aesthetic preferences, it is advisable to carry out the signaling unit in outwardly dissimilar - at least two - designs.

Namely, mainly for men, the option is intended when the alarm unit is made in the form of a multifunctional electronic wristwatch and additionally contains a clock circuit connected to a common alarm unit and an alphanumeric display containing familiarity, designed to display the current time.

The female part of consumers, mainly young girls, should like the option when the alarm unit is made in the form of a soft toy, such as a fluffy pompom, and contains a miniature electro-acoustic transducer that supports the transmission of all programmed signals in sound form.

The described detector works as follows. As long as all sources of electromagnetic waves provided for by programming are within a given radius of action, their code sequences are received by the receiving part of the signaling unit, detected by the detector, and fed to a digital information processing unit. In this block, the received sequences are compared with the entire pre-programmed set of such sequences, and if at least one of them does not coincide for a specified period of time, the signaling block signals a loss, and the update information is determined by the code sequence that was not found to match received signal.
