Synchronized infrared beacon / infrared detection system
First Claim
1. A synchronized infrared beacon/infrared detection system, comprising:
- an infrared beacon module configured to generate a time-varying encoded infrared signal;
an infrared detector module configured to capture the infrared signal;
wherein the beacon module and/or the detector module are configured to generate a synchronization signal and to provide the synchronization signal directly between the beacon module and the detector module to control the timing between the beacon module and the detector module; and
a processor configured to analyze the infrared signal captured by the detector module, wherein the processor is configured to recognize and decode the infrared signal to provide data communication directly between the beacon module and the detector module when synchronization based on the synchronization signal is not established between the beacon module and the detector module.

Abstract
A synchronized infrared beacon/infrared detector system. The system may include (A) an infrared beacon module configured to generate a time-varying encoded infrared signal, (B) an infrared detector module configured to capture the encoded infrared signal generated by the beacon module, (C) a synchronizer configured to generate a synchronization signal that controls timing of the beacon module and the detector module, and (D) a processor, in communication with the detector module, configured to analyze the infrared signal captured by the detector module. The infrared signal may be modulated at frequencies undetectable by human vision. The synchronizer signal may be produced independent of the capture of, and without input from, the infrared signal.

18. A method, comprising:
-
generating an encoded infrared signal comprising an emission of radiation using a beacon module; detecting the signal using a detector module; synchronizing between the beacon and detector modules, using a synchronization signal provided directly between the beacon module and the detector module, wherein the synchronization signal is provided from the beacon module to the detector module and/or from the detector module to the beacon module, so that there is a defined and predetermined relationship between the emission of radiation by the beacon module and the detection of the radiation by the detector module; tracking the beacon module by extracting a flashing frequency profile from the infrared signal; comparing the extracted profile to a desired profile; and transmitting an activation signal to the detector module only if the extracted profile matches the desired profile, independent of the synchronization signal. - View Dependent Claims (19)
