20120170939METHOD AND SYSTEM FOR ASYNCHRONOUS LAMP IDENTIFICATION - The invention relates to embedding data into a luminance output generated by an illumination system comprising a light source and a controller. The controller is configured to embed data by modulating a drive signal applied to the light source with an information signal comprising a shifted base code and a synchronization code. The synchronization code serves to provide synchronization for the receiver, while the shifted base code serves to carry the embedded data. A cyclic phase shift that is applied to a base code to generate the shifted base code corresponds to particular data, such as, for example, light source identification, that needs to be embedded into the luminance output of the illumination system. In this manner, data may be embedded into the luminance output generated by a light source without requiring synchronization of this light source with other light sources.07-05-2012
20090060513REMOTE OPTICAL CONTROL OF ELECTRICAL CIRCUITS - An optical controlling circuit and an electrical controlled circuit such as a motor control circuit are interconnected by an electro-optic interface. A passive optical switch located in the optical circuit at a position remote from the electrical circuit is physically actuated to generate a change in optical transmission state of the optical circuit.

20100202779IrDA transceiver module that also functions as remote control IR transmitter - The infrared LED of an IrDA module transmits IR energy with a peak wavelength (for example, 875 nm) appropriate for IrDA communication. This peak wavelength is lower than is the wavelength (for example, 940 nm) used in ordinary IR remote controls (RC). The IrDA LED does, however, transmit some energy at the wavelength of the peak sensitivity of an RC receiver. When making an IrDA transmission, the IrDA LED is driven with a lower amount of current. When making an RC transmission, the IrDA LED is driven with an increased amount of current such that higher wavelength emissions received by the RC receiver are of adequate power to realize RC communication. A passive circuit is disclosed for automatically increasing IrDA LED current during RC transmissions. The circuit involves an inductor that shunts current around a current-limiting resistor used to limit LED drive current.08-12-2010
