Assignee:

LoJack Operating Company LP - Westwood MA

International Classification:

B60R 25/10

US Classification:

340428, 340933

Abstract:

A vehicle locating unit with a receiver for receiving a signal from a network of communication sources, a transponder activated when a communication source sends a message to the receiver, and a power supply regulating circuit for regulating a nominal input voltage and powering the receiver and the transponder. A protection circuit is responsive to an injected input voltage and configured to clamp the injected (high level) input voltage at a predetermined maximum voltage.

International Classification:

H04B 1/16

US Classification:

4553435, 455 6711, 455425, 4555501, 370311

Abstract:

A vehicle locating unit with improved power management. A receiver receives a signal from a network of communication sources. A signal strength monitoring subsystem determines which of the communication sources are transmitting the strongest signals. A power management subsystem is responsive to the signal strength monitoring subsystem and is configured to alternatively enter sleep and wake-up modes, synchronize the wake-up mode to the communication source transmitting the strongest signal, and test the signal strength of at least one additional communication source according to a predefined sequence.

International Classification:

H04B 17/00

US Classification:

455 6711, 4553435, 455425, 4555501, 370311

Abstract:

A method of checking messages from a network of communication sources includes initially testing the signal strength of a plurality of communication sources, storing the identity of the communication sources with the two strongest signals, and alternatively entering a sleep mode and a wake-up mode, the wake-up mode synchronized to the communication source with the strongest signal. The method further includes testing the signal strength of one additional communication source, switching synchronization to the additional communication source if said source presents a signal stronger than the signal of a stored communication source with the strongest signal, and replacing the identity of any stored communication source if an additional communication sources tested in sequence presents a signal stronger than the signal of said stored communication source.

US Classification:

340988000, 340428000

Abstract:

A vehicle locating unit features a receiver which receives a signal from a network of communication sources and a transponder activated when a communication source sends a message to the receiver. There is a transmitter for sending signals to the communication sources and a proof of life subsystem configured to periodically send a proof of life message via the transmitter to the communication sources.
