121 Communication system US547578 1975-02-06 US3968435A 1976-07-06 Harris A. Stover
An electronic short range communication system which allows communication between two or more parties who are fairly close to each other and which allows communication between parties having the communication equipment without interfering with those who do not have communication equipment. The equipment has a definite range limit so as to prevent undesirable interference with other similar systems located beyond a reasonable distance. This system also permits communication from the nearest units of the system so as to override communication originating from more remote units.
122 Limited range radiocommunication system US3760278D 1971-12-15 US3760278A 1973-09-18 NARBAITS JAUREGUY J; BILLOTTET H
A fixed control station in a zone of high traffic density exchanges information with mobile stations aboard vehicles within that zone by short-range radiocommunication. The control station has an antenna in the form of a coaxial cable, with leakage losses, terminated by a dissipative load at one end while its other end is coupled to a transmitter supplying it with a frequency-modulated outgoing carrier destined for the vehicles within range. The outer conductor of the cable is grounded, at its end proximal to the load, through a parallel-resonant network tuned to the frequency of an incoming carrier from transmitterequipped vehicles; the other end of this conductor, remote from the load, is grounded through a similarly tuned circuit whose inductive branch forms the primary of a transformer coupling it to an associated receiver. A vehicle equipped with a car radio may have switchover means for selectively listening in on a radio program or on traffic information from the control station; a monitoring relay may respond to such traffic information to reverse a switch normally positioned for radio reception.

130 PET ANIMAL COLLAR FOR HEALTH&VITAL SIGNS MONITORING, ALERT AND DIAGNOSIS EP15737536.1 2015-01-15 EP3094173A1 2016-11-23 MENKES, Avi; BUKCHIN, Michael; ZAKHAROV, Michael; DAGAN, Asaf
A system for monitoring vital signs of a pet animal comprises an annular band, an accelerometer configured to measure at least one of resting patterns, activity patterns, movement patterns, position patterns relating to, for example the pet animal relieving itself, lameness and scratching, and a non-accelerometer sensor configured to measure at least one of the following non-accelerometer-measured bioparameters of the pet animal: temperature, pulse rate, respiration rate. One or more processors are configured to receive sensor output data and reference data concerning the measured bioparameters of the pet animal or of a population of the pet animal, and determine a suspicion of a specific medical condition by: (i) scoring at least two bioparameters and comparing a cumulative score to a threshold cumulative score or to a threshold cumulative range; or (ii) identifying an abnormal pattern. The processor(s) may send an alert if at least one specific medical condition is suspected.

135 TELELOOP SYSTEM EP03753342.9 2003-10-09 EP1550350B1 2008-07-30 SORRIG, Allan
The present invention relates to a teleloop system for representing a stereo audio signal by an electromagnetic signal to a listener using a hearing aid with a telecoil. The first and second teleloop have a shape and a size, whereby the electromagnetic signal from the first teleloop and the second teleloop to respectively the left and right ear is available within an area enabling the listener to move within said are and still receive the first and second audio channel. An advantage of the teleloop system is that the user will not have to wear any extra gear when using the system. Further because of the shape and size of each teleloop, it is possible to the listener to move the head without experiencing fallouts on the audio interception. Because of the optimised design of the teleloops ensuring an optimised transfer of energy from the teleloops to the telecoils, the level of the electromagnetic signal can be held at a low level, which minimises the risk on one telecoil receiving electromagnetic signals from both teleloops.

The claimed subject matter provides a system and/or a method that facilitates connecting a wireless device to a secure network. A device can establish a near field communication link with a verified device on a network, wherein the near field communication link can be a secure and/or encrypted link to provision the device without compromising security constraints within the network. An installation component can invoke the transfer of provisioning data to the network via the near field communication link to secure a wireless connection for the device to the network.

138 Hörgerät mit drahtlosem Übertragungssytem und entsprechendes Übertragungsverfahren EP04026930.0 2004-11-12 EP1538873A2 2005-06-08 Niederdränk, Torsten, Dr.

Bidirektionale Datenkommunikation soll auch in Hörgeräten realisiert werden können, die nur über einen beschränkten Einbauraum verfügen. Daher ist insbesondere vorgesehen, den Hörer (H), d.h. die elektroakustische Wandlereinheit, als Sender und die Telefonspule (L) als Empfänger für hochfrequente Signalanteile zu nutzen. Dadurch kann auf den Einbau einer für Sende- und Empfangsvorgänge optimierte, in der Regel voluminöse, zusätzliche Antenne verzichtet werden. Gegebenenfalls kann als reine Empfangsantenne für hochfrequente Signale auch eine kleine zusätzliche Antenne eingesetzt werden.

139 LOW POWER SIGNAL TRANSMISSION EP03756088.5 2003-06-02 EP1509282A1 2005-03-02 HOCHMAIR, Erwin; HOCHMAIR, Ingeborg
A low-power implant system. The system includes an implant for implantation into a person, such as a cochlear implant or a middle ear implant. The implant is capable of communicating with a device via transmission of ultra wideband pulses. The device may be adapted to be worn external to the person, or may be a second implant. So as to conserve battery power, the transmitted ultra wideband pulses may have a low duty cycle of approximately 1/1000 or less. Power savings may also be realized by using time-gating amplifiers in the implant and/or device receiver.
140 MOBILE PHONE AND HANDS-FREE KIT WITH INDUCTIVE LINK EP02751382.9 2002-08-06 EP1415458A1 2004-05-06 Aman, James Edward
A mobile phone has a transmitter coil forming a first part of an inductive link for forwarding sound signals received by the mobile phone and an earpiece for fitting into an ear canal and having a housing of which at least a proximal portion can fit within the ear canal. The housing contains a receiver coil forming a second part of the inductive link for receiving sound signals from the transmitter, an amplifier for amplifying the sound signals received by the receiver coil, a transducer for reproducing the received sound signals; and a space for a battery. The amplifier has means responsive to received signal level for squelching its output at low levels of detected signal.
