摘要： A cable communication system (100) where a control unit (110) sends operation parameters to subscriber units (130) and the subscriber units (130) respond by modifying the method of communication. Also, the subscriber units (130) send messages which include information on the subscriber unit (130) and the capabilities of the subscriber unit (130). Furthermore, the control unit (110) efficiently manages the system 100 by monitoring the capabilities and instructing the subscriber units (130) on-how to communicate on the system (100). Such management allows for the migration of subscriber units (170) from one service area (140) to another (190) without the disruption of service. In addition, initialization of subscriber units (130) may be accomplished over the cable and does not require an operator at the subscriber location.

摘要： A system for producing an output signal representing movement of an object's surface has a continuous wave (CW) signal source for producing an CW signal directed at the object's surface. The CW signal is produced at a first frequency. A receiving element receives a signal reflected from the object's surface when the CW signal hits this surface. A down-converting frequency mixer converts the received signal into a signal of a second frequency lower than the first frequency. The frequency mixer is configured to produce an output signal representing an amplitude-modulated (AM) component of the received signal and having a parameter representing movement of the object's surface.

摘要： This transmission system comprises a station of a first type and a plurality of stations of a second type which include a transmitting part having a transmit timing controller for transmitting data at a transmit timing and a receiving part having synchronizing circuits for synchronization with data transmitted from the station of the first type. When the stations of the second type are moving, their transmit timing is modified to facilitate the synchronization of the reception of the station by solely being based on the receive timing at these stations of the second type.

摘要： A system and method are disclosed for providing multiple broadcasts of audio information to spectators attending a sporting event. The system comprises radio receivers for picking up broadcasts of local and non-local events, a transmitter and antenna for transmitting the broadcasts within a predetermined frequency range to a limited area surrounding the local event. Radios provided to spectators attending the event are a FM narrow-band receiver for accessing the multiple broadcasts transmitted within the predetermined frequency range.
