Definitions

  • the invention relates to a system for detecting the proximity of an object or a person and includes a base station which could be fixed or mobile and at least one mobile unit related to said object or person.
  • detectors for proximity which react on the proximity of a metallic part. These detectors for proximity generally works according to the principle of a modification of a magnetic field or a modification of the resonance frequency of a resonance circuit. These detectors for proximity allow the location of an object or a person if this object and this person carries a metallic part. The detection could only be made within a limited distance. It is also known to detect the presence of a person by means of a detector sensitive to infrared radiation.
  • the invention refers to a system allowing the detection of the presence of a mobile unit in an area around a base station the extension of which area could be adjusted. Typically the base station is carried by a physical person but could also be fixed.
  • the mobile unit(s) are usually related to objects or physical per- sons to be surveyed. The base station could activate an alarm depending on the detected presence or non-presence of the mobile unit(s) in the surveyed area.
  • the system could obviously be used for the surveillance of an object related to said mobile unit or e.g. prevent that such an object will be forgotten by a person carrying a base station which person is not supposed to leave e.g. a room without carrying the surveyed object.
  • One embodiment of the system for detection according to the invention is characterised in that it comprises a radio frequency transmitter, forming part of the mobile unit which is arranged to be fixed on the object or the person or to be integrated in said object the proximity of which should be detected. Said transmitter is intermittently transmitting a signal e.g. with a given frequency.
  • the system is further comprising a receiver forming part of a base station capable of receiving the signal with the given frequency which receiver further could comprise means for adjusting the reception sensitivity, means for detection of reception, means for detection of absence of reception, means for commutation for activating either the means for the detection of presence of reception or the means for detection of absence of reception and means for emitting an acoustical, optical or tactile detection signal.
  • this unit is sending out a detection signal, e.g. an acoustical signal, signifying either the presence of the object or the person within a predetermined distance from the base station or the non-presence within the same distance.
  • a detection signal e.g. an acoustical signal
  • the acoustical signal is not generated by the object to survey but by the receiver.
  • the base station may comprise several circuits arranged for the reception of different frequencies which allows the survey of several mobile units sending out signals with e.g. different frequencies.
  • the base station advantageously comprises means for identification and displaying the different mobile units.
  • the identification of the different mobile units could of course also be made if the mobile units are transmitting at the same frequency in e.g. PCM mode.
  • the battery dimensions and weight, rechargeable or not are decisive for the design parameters of especially the mobile units.
  • the mobile unit could be fixed by means of different means on the object or the person which should be surveyed, e.g. by means of a band of Velcro (trademark).
  • Another example of system for the fixation comprises a small tag advantageously glued to the object to survey provided with a loop of a flexible material fixing the mobile unit.
  • the mobile unit as well as the base station could also be integrated in an object, as e.g. in a watch, handbag, belt, portable telephone etc..
  • One way to reduce the power needed by the mobile unit is to activate the transmitter intermittently, e.g. a few milliseconds or tens of milliseconds each minute.
  • the receiver of the base station could advantageously be equipped with means for adjusting the sensitivity of the reception of the signals from the transmitters in order to be able to change the distance for the detection of the mobile unit(s).
  • This distance could e.g. be set to values between 1 and 20 meters.
  • the receiver of the base station is equipped with means allowing to raise the sensitivity of the reception during a certain time, e.g. from 1 two 5 minutes, in order to allow the person carrying the base station to temporarily move outside the area of detection without causing an alarm.
  • the receiver could also be equipped with means for interruption of the reception during a certain time, e.g. 1 to 5 minutes with automatic reset.
  • the interruption time could also be introduced in the receiver by means of pulses on a pushbutton or similar whereby every pulse e.g. could corresponds to 1 minute of interruption.
  • the receiver could also be equipped with means, e.g. in the form of a pushbutton, connected in parallel to the commutation means for presence/absence making it possible to easily verify the presence of an object when the base station is set to detect absence.
  • This push-button could also be used when searching an object.
  • the base station is additionally provided with a transmitter and the mobile unit is additionally provided with a receiver.
  • the base station is in this embodiment intermittently sending out modulated "question signals" urging the mobile unit or units to respond. Said signal could be addressing one specific mobile unit at a time or all the mobile units at the same time. In the first case the base station is waiting for the response from the addressed mobile unit before the next one is addressed. In the second case each mobile unit could be programmed for a specific time delay between incoming question signal and the response signal.
  • communications from the base station to the mobile unit utilise amplitude modulated radio signals which are easily demodulated. However, other modulation principles could also be used.
  • the mobile units could respond by electrically switching the antenna from being an absorber of radio frequency radiation to being a reflector to radiation. Signals reflected in this way by an antenna forming part of the mobile unit is in this description considered to be "transmitted" by the mobile unit. Data and software stored in the mobile unit could control the switching of the antenna thereby modulating the reflected signal which will be demodulated at the base station. In this way data could be transferred from the mobile unit to the base station.
  • the data stored in the mobile unit could be fixed or varying due to some parameter. In the simple case data could e.g. be a fixed identification number of the mobile unit.
  • a system according to the above will be more flexible in that the power used by the mobile unit(s) will be very low and to some extent can be controlled from the base station.
  • the signal sent out from the base station could be used for "waking up” the mobile units from a low power “sleeping" state.

Abstract

Un système permettant de détecter la proximité d'un objet ou d'une personne comprend une station de base et au moins une unité mobile, cette dernière étant prévue pour être fixée sur ledit objet ou ladite personne ou pour être incorporé dans ledit objet dont la proximité par rapport à ladite station de base doit être détectée. L'unité mobile comprend un émetteur par radiofréquence ou un réflecteur qui émet ou réfléchit un signal. La station de base est constituée d'un récepteur capable de recevoir le signal envoyé ou réfléchi par la ou les unités mobiles et un système de détection de présence de réception, un système de détection d'absence de réception et un système qui émet un signal de détection acoustique, optique ou tactile ou un signal d'alarme. Le système se caractérise en ce que ledit émetteur faisant partie de l'unité mobile émet de manière intermittente et en ce que ladite station de base est en outre équipée d'un système de commutation permettant d'activer soit le système de détection de présence de réception soit le système de détection d'absence de réception.
