Abstract: A switch circuit for a cellular radiotelephone operable in a TDMA communication scheme. The switch circuit (206) is disposed upon a plurality of tandemly-positioned ceramic substrates having transmission lines (250) disposed upon one of the ceramic substrates. The switch circuit alternately connects transmitter circuitry (212) to an antenna (218) or receiver circuitry (224) to the antenna (218), thereby alternately to permit transmission or reception of signals generated by, or received by the radiotelephone. Because circuits disposed upon ceramic materials are of low insertion losses, the switch circuit (206) is advantageously utilized to form a portion of the radiotelephone.

Abstract: A display system (100) includes a liquid cristal display (140) which incorporates annunciator areas (142). Each annunciator area (142) has an aperture (146, 147, 148), independently controlled, to allow the passage of light through the annunciator area (142). Independently controlled illumination (160, 210, 212, 214) is positioned behind each annunciator area (142). The passage of light through each annunciator area (142) is controlled by opening and closing the aperture (146, 147, 148).

Abstract: A nondirectional antenna assembly (100), and associated method, for a radio operative at high frequencies, such as at frequencies of approximately 1.8 Gigahertz. A first antenna portion, formed of a one-half wavelength, helical winding (124) is supported at a distal side of a nonconductive whip (106). A second antenna portion, comprised of a helical winding (130) supported at a proximal side of the nonconductive whip, and a one-quarter wave helical winding (136), connected to radio circuitry of the radio transceiver, couples the first antenna portion to the radio circuitry. Because the first antenna portion (124) is positioned at a distal side of the nonconductive whip (106), shadowing occurring as a result of positioning the radio transceiver proximate to a user during operation thereof is less likely to interfere with operation of the radio transceiver.

Abstract: A method of reducing control channel traffic in a radio communication system employs a scheme that defines paging areas. A paging area comprises at least a first location area and other coverage areas. Radio communication is provided that exhibits a degree of co-channel interference among control channels serving coverage areas that are associated with different location areas. According to the invention, a record is provided at the fixed end for each of the coverage areas. These records have elements that include an identification (ID) for the associated location area, and an identification for supported coverage areas, which together define a paging area. The elements of the record are transmitted by the fixed end, and the record elements are retrieved (304) by a mobile. The mobile then determines (306) whether or not he is still within the same paging area corresponding to the location area in which he was last registered. Accordingly, the mobile needs not re-register each time it travels from one location area to another.

Abstract: A frequency control circuit (350), and associated method (700), for a receiver operative to receive a TDMA signal transmitted by a transmitter in a TDMA communication system. A first frequency detector (452) generates a first frequency control signal (468). A second frequency detector, comprised of a portion of a decision-directed demodulator (450), generates a second frequency control signal (496). The first frequency control signal (468) is utilized to effectuate frequency control when a signal is continuously received by the receiver, such as times immediately subsequent to initial powering of the receiver as the receiver becomes synchronized with the TDMA signal transmitted thereto. Once a receiver becomes synchronized to the transmitter, the receiver needs only be powered during intermittent time periods when the TDMA signal is transmitted to the receiver. The second frequency control signal (496) is utilized to effectuate frequency control only after the receiver is synchronized with the transmitter to permit intermittent operation of the receiver, and the frequency differences between the signal transmitted to the receiver and a receiver-oscillator oscillation frequency is less than a maximum level.

Abstract translation: 一种频率控制电路（350）和相关联的方法（700），用于接收在TDMA通信系统中由发射机发送的TDMA信号的接收机。 第一频率检测器（452）产生第一频率控制信号（468）。 由决策导向解调器（450）的一部分组成的第二频率检测器产生第二频率控制信号（496）。 第一频率控制信号（468）用于当接收机连续接收信号时，例如当接收机与发送到其的TDMA信号同步时，紧接在接收机的初始供电之后的时间，来实现频率控制。 一旦接收机变得与发射机同步，接收机只需要在TDMA信号发射到接收机的间歇时间段内供电。 第二频率控制信号（496）仅在接收机与发射机同步才能实现频率控制，以允许接收机的间歇操作，并且发射到接收机的信号与接收机振荡器振荡频率之间的频率差为 小于最高水平。
