20080313479 | Device and Method for Media Access Control - A method for media access control, the method includes generating at least one media access grant in response to at least one media access request. The method is characterized by monitoring a data line, while maintaining at least a clock line in a low power mode, to detect at least one media access request generated by at least one component connected to the data line and to the clock line; and forcing the at least clock line to exit the low power mode and starting a contention prevention period, when the media access controller or at least one component requests to access the data line. | 12-18-2008 |
20090175393 | METHOD AND DEVICE FOR FRAME SYNCHRONIZATION - A method for frame synchronization, the method includes providing a high frequency clock signal over a clock line during a transmission of information over a data line connected to a media access controller and to at least one component; characterized by defining a short synchronization period; processing at least one signal conveyed over the data line during the short synchronization period to determine a presence of a synchronization error; and maintaining at least the clock line in a low power mode when the data line is substantially idle. | 07-09-2009 |

20100117562 | POWER SUPPLY CONTROLLER FOR MULTIPLE LIGHTING COMPONENTS - A power supply controller for a plurality of lighting components in a battery-powered apparatus. The power supply controller comprises a current source common to the lighting components, and a sequencer for coupling the current source sequentially to each of the lighting components with a repetition rate substantially faster than the flicker perception rate. Each of the lighting components comprises a respective array of lighting elements connected in series to receive the same current as the other lighting elements of the same lighting component. | 05-13-2010 |
20100301907 | SYSTEM AND METHOD FOR SECURE REAL TIME CLOCKS - A secure real time clock (RTC) system is provided, comprising a secure RTC, a frequency signal generator, and a frequency adjuster connected between the secure RTC and the frequency signal generator to receive a signal having a first frequency from the frequency signal generator. On receipt of a first control signal the frequency adjuster outputs the signal having the first frequency to the secure RTC, and on receipt of a second control signal the frequency adjuster adjusts the signal having the first frequency to generate a signal having a second frequency, the second frequency being lower than the first frequency, and outputs the signal having the second frequency to the secure RTC. A clock line transmits the signal having the first frequency and the signal having the second frequency from the frequency adjuster to the secure RTC, and has a first power consumption when transmitting the signal having the first frequency and a second power consumption when transmitting the signal having the second frequency, the first power consumption being greater than the second power consumption. | 12-02-2010 |
