Abstract: An LED lighting control system incorporating a control IC for fast control of LED current in a switching Buck-type power supply through dedicated power supply control hardware with slow changing signals of temperature and input under control of firmware. The control IC optimizes the use of power from the source and optimizes the operating efficiency of the LED output while providing for a plurality of LED devices to be powered in parallel by a single controller.

Abstract: A device interface selectively acquires patient physiological parameter data. An acquisition processor acquires physiological data from a patient. A communication processor is coupled to an optical communication pathway for receiving optical signals from a source. A conversion processor electrically coupled to the acquisition processor and communication processor converts a first optical power signal at a first frequency and received via the optical communication pathway using the communication processor, to a first electrical signal for providing power to the device interface. The conversion processor converts an optical control signal at a second frequency different from the first frequency and received via the optical communication pathway using the communication processor, to a second electrical signal for providing control data to the acquisition processor directing the acquisition processor to acquire at least one physiological parameter from a patient.

Abstract: A system and method to produce video data by transmitting time information with the video data. The equivalent horizontal and vertical timing at the reception device are reconstructed. The method includes receiving one or more control packets specifying a quantity of pixels in an associated data packet. Data packets are received that contain the quantity of pixels specified in the associated control packet. A time interval between received control packets is determined. A running average of the time intervals is calculated and a time interval of a current control packet is determined. The running average is compared with the time interval of the current control packet. A clock frequency is adjusted as a function of the comparing step.

Abstract: An optical mouse device that includes a light source and an object, such as an operator's hand or other instrument that is disposed in the path of the light energy to reflect the light energy emitted from the light source. At least one sensor unit receives the reflected light energy and generates electrical signals based on the received reflected light energy. The electrical signals may be used to control an apparatus, such as a cursor on a computer screen, operating table, or industrial machinery.
