| A magnetic induction system is disclosed, which has antenna diversity at the transmitter side, but which does not require a bidirectional link to pass information regarding received signal quality back to the transmitter. The system uses a time division multiplexing access (TDMA) arrangement, to transmit the same, or correlated, information with a level of redundancy, from two, or more, antenna to at least a receiver. The or each receiver is configured to determine a received signal quality from the channel received from one antenna, and, in response to inadequate signal quality, to switch to another antenna.A receiver, and a transmitter for such a magnetic induction system are also disclosed, as is an associated method.A non-limiting application of such a system is in binaural hearing aids, in which antenna diversity is preferred at the transmitter because of space limitations. | ||||||

| The present invention relates to secure paring of electronically controlled devices adapted to communicate with each other. Thus, a medical system is provided comprising a first unit and a second unit, the system comprising first means of communication allowing a first group of data types to be transmitted between the first unit and the second unit, the first unit comprising an acoustic transducer having a transducer coil with a plurality of windings, the transducer coil serving as an antenna for wireless signals transmitted between the first and second units.

| 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 and medium frequency radios, including mobile, portable and personal-carried radios, coupled to electrical conductors 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, 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. | ||||||

| A transmission system for transmission of audio voltage signals has a first transmission portion which includes a cable (16) coupled to a first face of a substantially flat cover member (22). The cable (16) and cover member (22) are integrally coupled to form one entity.

A second transmission portion includes a printed circuit board (32) fixedly secured within an insulating casing (40) through an access opening. The printed circuit board has a transmission circuit coupled to an antenna (38). Connection of the first and second transmission portions is facilitated by connection plugs (34, 36) of the second transmission portion making contact with the socket contacts (24, 26) of the first transmission portion. | ||||||
| 260 | Induction-based assistive listening system | US349515 | 1989-05-09 | US4908869A | 1990-03-13 | Norman Lederman |
| A multiple-loop magnetic induction system for improving communication with the hearing-impaired or to people in general who wish to listen privately to speech or music while being in the company of others or at a public location. The invention uses a particular grid made up of several electrical conductors as a means of generating an audio-frequency magnetic field which in turn couples to the telephone coils already present in most hearing aid units. The audio-frequency magnetic field is correlated to sound waveforms--speech, music, etc.--which is to be communicated. The grid configuration is selected so as to produce an end signal which is substantially independent of the location and the orientation of the hearing aid device within the area of the grid and which falls off precipitously outside of the region defined by the grid. The conductors which make up the grid configuration are enveloped in a flexible, lightweight matting which can be unrolled in the area to be addressed. | ||||||
