摘要： Synchronization for achieving low power battery operation of a vehicle locating unit in a stolen vehicle recovery system whose radio receiver receives periodic transmissions, includes receiving periodic transmissions; turning on a radio receiver for a limited time to detect an expected message; if an expected message is not found, turning off the receiver and turning it on again after a time asynchronous with the transmission period; and after finding an expected message, waiting for the period of the transmissions less the length of an expected message and then looking for a synchronization symbol in the expected message and synchronizing subsequent actuation of the receiver using that synchronization symbol.

摘要： A recovery system and method with repeating communication functionality includes a station configured to send a first message and at least a first remote transmitting unit responsive to the central station and configured to transmit a second message to a locating unit. At least a second remote transmitting unit includes a receiver which receives the second message, a controller configured to process the second message, and a transmitter for transmitting a third message to the locating unit.

摘要： A recovery system with repeating communication capabilities. The system includes a station configured to send an activation message, at least a first “primary” remote transmitting unit responsive to the station and configured to transmit the activation message and at least a one “secondary” remote transmitting unit. That unit includes a receiver which receives the activation message, a transmitter for transmitting the activation message, and a controller responsive to the receiver and controlling the transmitter. The controller is programmed to transmit the activation message and then automatically stop transmission of the activation message after a predetermined time period unless the activation message is again received.
摘要翻译：具有重复通信能力的恢复系统。所述系统包括被配置为发送激活消息的站，响应于所述站并且被配置为发送所述激活消息的至少第一“主要”远程发送单元和至少一个“次要”远程发送单元。该单元包括接收激活消息的接收机，用于发送激活消息的发射机，以及响应于接收机并控制发射机的控制器。控制器被编程为发送激活消息，然后在预定时间段之后自动停止激活消息的传输，除非再次接收到激活消息。
