  • Electronic device having a position sensor
    Patent number: 7903085
    Abstract: The present invention provides an electronic device comprising: —a position sensor (102; 302; 502), —a first integrated circuit component (106; 306; 506) coupled to the position sensor for acquisition of position data (112; 312), —a memory (114; 314) for storing the position data, a second integrated circuit component (108; 308), wherein the first integrated circuit component comprises means (110; 348) for signalling the acquisition of the position data to the second integrated circuit component, the second integrated circuit component comprising means (108; 364, 374) for reading the position data from the memory in response to the signalling.

  • Crystal reference clock and radio localization receiver
    Patent number: 7728684
    Abstract: Device and method for temperature compensation in a clock oscillator using quartz crystals, which integrates dual crystal oscillators. The minimal power consumption is achieved through an efficient use of a processor in charge of the synchronization of the two oscillators. The invention is particularly adapted for the provision of a precise reference clock in portable radiolocalization devices.
