    摘要: A voice amplifier for attachment to a mask has a sound reflector that faces outwardly of the mask when the voice amplifier is attached to the mask. A speaker faces inwards towards the sound reflector. Sound waves emanate from the speaker inward towards the sound reflector, reflect off the sound reflector and exit the voice amplifier through an outer peripheral gap and travel outwardly from the mask. The voice amplifier has an on/off switch mounted on the front of the voice amplifier. The voice amplifier cover has a front wall with a front surface facing away from the mask. The narrow end of the speaker is located closer to the front wall of the cover than the wide end. The cover front wall follows the profile of the speaker in a direction from the narrow end to the wide end of the speaker.

    摘要: A system to provide narrowcast communications uses adaptive data rate control to individual subscribers such that the effects of precipitation or other link conditions, which are not common to all subscribers, is mitigated. The invention takes advantage of the fact that the narrowcast data consist of packets which are individually addressed to specific subscribers, or groups of subscribers. The narrowcast data is communicated on a plurality of channels, each of potentially differing data rates. The subscribers are assigned a particular channel, based upon their link quality, to receive packets addressed to them. The lower data rate channel will be less affected by adverse link conditions and are hence assigned to subscribers most likely to incur adverse link conditions.

    摘要: This invention is a multiple access communication technique by which a multitude of transmitters communicate with receivers using direct sequence spread spectrum signaling. The direct sequence codes are reused by a large number of simultaneous transmitters, so the system is named Code Reuse Multiple Access (“CRMA”). This reuse method requires only a small number of codes relative to the number of simultaneous transmitters, and can use as few as one code for all the users. The direct sequence codes are not required to have special properties such as maximal length. The lengths of the spreading codes employed are not necessarily related to the bit or symbol interval. CRMA can be implemented on a Paired Carrier Multiple Access (“PCMA”) system with or without a novel receiver structure which is also described. In an environment having virtual channels, a clock is derived from the received signal in the uplink by sampling the signal to detect symbol edges.
