95 TELELOOP SYSTEM EP03753342.9 2003-10-09 EP1550350A1 2005-07-06 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.
96 SHORT RANGE INDUCTIVELY COUPLED COMMUNICATION SYSTEM EMPLOYING TIME VARIANT MODULATION EP94922045.3 1994-06-28 EP0706732B1 2001-12-19 SHARMA, Madan, M.; YOUNG, Robert, Francis; STROHALLEN, Gene, Michael
A short range magnetically coupled wireless communication system employs time variant modulation of a high repetition rate pulse stream and magnetic coupling between a transmission magnetic element and a receiving magnetic element. The pulse stream is modulated by an input audio frequency signal in the time domain, for example, through pulse position modulation, pulse width modulation or pulse symmetry modulation. The receiving magnetic element is coupled to a demodulator circuit which detects the transmitted pulses induced in the receiving magnetic element and reproduces the audio frequency signal. Transmission over short range is thus efficiently accomplished through magnetic coupling in a simple, low cost, low power consumption communication system.

A cordless headset, requiring very low power using Time Variant Modulation (TVM) for reception of a magnetic signal and TVM of RF or infrared as the transmitter. The headset area or zone of operations is defined by the magnetic field that the headset operates within and uses a handshake protocol that takes advantage of the TVM fixed clock period. The headset communicates with a base station that includes a TVM transmitter and loop for transmitting a TVM signal to the cordless headset, and a RF or infrared receiver capable of receiving TVM signals from the headset. The base station also contains the headset protocol logic for controlling the headset transmission. The headset and base station receiver can both be fixed, mobile or portable and vary with respect to orientation and distance from each other. The receiver circuits in both base station and headset automatically adjust to the variance in signal strength.

100 Medium frequency mine communication system EP88108355.4 1988-05-25 EP0292950A3 1990-07-18 Stolarczyk, Larry G.; Smoker, Kurt A.; Boese, Gerald J.; Mondt, William E.; Hasenack, Marvin L., Jr.; Zappanti, James L.; Smith, Seth A.; Moore, Edward D.

A method for using an underground mine communication system to effect minewide communication and an intrinsically safe current limiter circuit for insuring that electrical equipment in the system will not cause incendiary conditions. The underground mine communication system comprises a plurality of repeaters (28) and medium frequency radios, including mobile (24), portable and personal-carried radios (26), coupled to electrical conductors (32) and natural waveguides existing in the earth by tuned loop antennas. Messages transmitted by the radios are carried to the repeaters by the conductors or coal seam waves. The repeaters amplify, replicate and retransmit the message at two different frequencies for transmission of the message to a surface base station and to other radios in the system. A paging system, which has a separate set of repeaters (29), is also coupled to the network of electrical conductors and natural waveguides by tuned loop antennas. The paging system alerts miners to contact the surface base station. Radios, pagers and repeaters in the system are equipped with the intrinsically safe current limiter circuit to preclude the development of incendiary conditions. The current limiter circuit comprises a series arrangement of a current trip circuit, a redundant current trip circuit and a current limiting field effect transistor controlled by a feedback control amplifier.
