摘要： A method in a radio communication device (110) for receiving a lengthy message comprises the steps of receiving an RF signal (300) comprising header information (310) and submessages (305), wherein each submessage (305) is a portion of the lengthy message, and comparing header information (310) corresponding to a submessage (305) with header information corresponding to previously stored submessages, If the header information (310) corresponding to the submessage (305) is not substantially equivalent to header information corresponding to at least one of the previously stored submessages, the submessage is stored in a memory (225). The method further comprises the step of combining the submessages (305), in response to the header information (310), to form the lengthy message.

摘要： The IF amplifier combines the high frequency and low noise figure characteristics of a cascode stage with the large signal handling capability and accurate gain control of a direct emitter coupled amplifier controlled by a constant current source. The amplifier uses a technique of alternately stacked cascode stages which results in minimizing both the total current drain and the value of DC potential necessary to operate the amplifier. A current mirror, independent of power supply variation, is used to control the gain of the amplifier and is also used to provide temperature compensation for amplifier gain. Special bias techniques along with the current mirror minimize the variation of the amplifier gain with respect to DC power supply variations. Novel use of semiconductor devices minimizes the number of leadout connections on an I.C. chip needed for attaching large external bypass capacitors.

摘要： A battery powered electronic device (105) for coupling to a host computer (205 ) comprises an interface (115) for transmitting data and an annunciator (340) for generating a sensible alert. The electronic device (105) further comprises interface monitoring circuitry (320) coupled to the interface (115) for determining an interface status as being active or inactive and voltage monitoring circuitry (360) coupled to a battery (355) for monitoring the battery voltage. Threshold detection circuitry (360) coupled to the voltage monitoring circuitry (360) detects that the battery voltage has exceeded a predetermined threshold voltage and generates a low battery signal in response thereto. A controller (320) receives the low battery signal and, in response thereto, provides a low battery indication to the interface (115) when the interface (115) has an active status and provides an activation signal to the annunciator (340) when the interface (115) has an inactive status.

摘要： A selective call terminal receives selective call information from a message originator. A transmission time is scheduled for the selective call message by a selective call system controller. A plurality of simulcast schedulers coupled to the controller receive and store the selective call message and the transmission time. The simulcast schedulers have an equalization time stored therein, the equalization times for each of the simulcast schedulers calculated by the system controller using simulcast receivers for measuring signal time differences between transmitters. The simulcast schedulers provide the selective call message to corresponding transmitters at a time to transmit the selective call message, the time determined by the transmission time and the equalization time. Transmitter settings and code types defining signalling protocol, data bit rate, carrier frequency and transmitter power, for each message are varied in accordance with information received from the system controller. Each simulcast scheduler can also function as a selective call terminal for a local selective call system.

摘要： The encoder which preferably produces a transmitted digital word which serves as an activation code for a single receiver or a group of receivers. The activation code effects only the receiver(s) that have previously detected their digital address and are therefore prepared to enter a message receive state. The activation code transmitted by the encoder will cue the receiver(s) simultaneously thereby allowing the encoder to send a single message to a plurality of receivers. The activation code also allows the encoder to interleave messages to receivers by utilizing the customary transmitter down time in a single message transmission. During this down time, the activation code allows the transmitter to begin transmission of a second message to a second receiver. The use of the activation code to interleave messages is especially important in tone and voice transmissions since it significantly increases the efficiency of a heavily loaded system.
摘要翻译：编码器优选地产生用作单个接收机或一组接收机的激活码的发送数字字。激活码仅影响先前检测到其数字地址的接收机，因此准备进入消息接收状态。由编码器发送的激活码同时提示接收机，从而允许编码器向多个接收机发送单个消息。激活码还允许编码器在单个消息传输中利用传统的发射机停机时间将消息交织到接收机。在该停机期间，激活码允许发射机开始向第二接收机发送第二消息。使用激活码来交织消息在音调和语音传输中尤其重要，因为它显着地提高了重负载系统的效率。
