Battery operated remote transceiver (BORT) system and method
First Claim
1. A system for reducing power consumption in remote communications, comprising:
- a system transceiver configured to transmit in a system transceiver message a count value and modulated communication data, said count value indicating a scheduled broadcast time for broadcast of the modulated communication data; and
a remote transceiver configured as the remote communication device to poll for the count value, to conserve power during a time period prior to the scheduled broadcast time, and to synchronize an on-time of the remote transceiver with the scheduled broadcast time.

Abstract
A system, method, and computer program product for reducing power consumption in remote communications, wherein a system transceiver transmits in a system transceiver message a count value and modulated communication data, and a remote transceiver polls for the count value indicative of a scheduled broadcast time for broadcast of the modulated communication data. The remote transceiver conserves power during a time period prior to the scheduled broadcast time and synchronizes an on-time of the remote transceiver with the scheduled broadcast time of the system transceiver. The remote transceiver conserves power both by polling rather than continuously listening and by entering a low-power sleep period for a time period prior to the scheduled broadcast time.

52. A system for acquiring a signal in remote communications comprising:
-
a system transmitter configured to transmit a signal which does not contain more than one “
0”
value symbol, said signal including a leader section and a data section;
a receiver configured to sample and store data samples from the transmitted signal including at least two symbols for at least two consecutive time periods; and
a correlation operator in the receiver configured to sequence through the stored data samples using a correlator of a length equal to one time period to increase a probability that a “
01”
sequence is read. - View Dependent Claims (53, 54, 55, 57, 58, 59)

61. A computer readable medium containing program instructions for execution on a computer system, which when executed by the computer system, causes the computer system to perform the steps of:
-
polling by a remote transceiver for a count value transmitted from a system transceiver;
conserving power in the remote transceiver during a time period prior to a scheduled broadcast time of modulated communication data from the system transceiver; and
synchronizing an on-time of the remote transceiver with the scheduled broadcast time of the system transceiver. - View Dependent Claims (62, 63, 64)
