    Abstract: In a time division, multiple access system, a base station (102) transmits an isochronous beacon (404, 422) at the start of each frame (400), conveying control and timing information. Following the isochronous beacon (404), isochronous time slots (414, 416, 418, 420) are dynamically allocated for communication of isochronous data. After communication of the isochronous data, the remainder of the frame (400) before the next isochronous beacon (422) is used for transmission of packets of asynchronous data. This technique gives priority to the isochronous data, which is real time, while also maximizing the bandwidth allocated for asynchronous data. A single transmitter circuit (124, 158) and receiver circuit (122, 156) at each station are used for communication of both isochronous data and asynchronous data.

    Abstract translation: 在时分多址接入系统中,基站(102)在每帧开始时发送等时信标(404,422),传送控制和定时信息。 在等时信标(404)之后,动态分配同步时隙(414,416,418,420)用于同步数据的通信。 在同步数据通信之后,在下一个同步信标(422)之前的帧(400)的剩余部分被用于异步数据分组的传输。 这种技术优先考虑实时的同步数据,同时最大化分配给异步数据的带宽。 每个站处的单个发射机电路(124,158)和接收机电路(122,156)用于同步数据和异步数据的通信。

    Abstract: A method for providing two-way calling between first and second handsets (402, 404) using a base station (406) and a paging terminal (412). The method for making the call includes storing a base line phone number for each line within the base station (406). A communication link is established between the first handset (402) and the base station (406) and between the base station (406) and the paging terminal (412). The paging terminal (412) prompts the caller for information to be sent to the second handset and the caller responds by entering a sequence that allows the base station itself to forward the base line phone number and an alias code, representing the identification of the first handset, to the paging terminal (412). The paging terminal (412) then pages the second handset (404) with the base line phone number and the alias code. Any communciations device may return the call by calling the base line phone number and entering the alias code, thus establishing a communications link with the first handset (402).

    Abstract: A base site circuit (38) for operating in a communication system (10) having a plurality of base sites capable of allocating a communication channel for use by a communication unit (16) in response to a communication channel request from the communication unit. The base site circuit includes a receiver (34) that operates in a low sensitivity mode when there are no communication channel requests received, and that operates in a high sensitivity mode which is activated by a control signal. The base site further includes a transmitter (34) which is activated by the control signal and a control circuit (32) coupled to both the receiver and the transmitter, for controlling the receiver and the transmitter. The control circuit (32) provides the control signal to the transmitter and to the receiver, in response to a communication channel request.

    Abstract: An electronic device (100) operating on a battery voltage (126) is disclosed having a regulator (108) for producing a first reference voltage (106) and a second reference voltage (110). The electronic device (100) includes an A/D converter (114) for comparing the battery voltage (126) to the first reference voltage (106) to produce a first sample. The A/D converter (114) also compares the second reference voltage (110) to the first reference voltage (106) to produce a second sample. The two samples are then subtracted at a micro-computer (112) to produce a difference sample. The micro-computer (112) compares the difference sample to a first value and detects low battery conditions when the difference sample is below the first value.

    Abstract: A method and apparatus are provided for generating a personalized radio channel playlist by simultaneously buffering tracks from multiple received channels from one or more source streams and selectively playing back tracks from the buffered channels. Navigation tools permit users to skip buffered songs in their playlist (e.g., skip forward and backward). Users can specify favorite channels for building personal playlists, or multiple default playlist channels can be provided (e.g., by genre). Thumbs up/down buttons on the radio receiver permit entering a song or artist being played back into a favorites list that is used to search all channels for matches or a banned list used to block songs from future playlists. A matched channel carrying the favorite can be added to a playlist. Segments on the playlist can be played back in full or truncated to facilitate preview of playlist segments.
