  • Patent number: 8170822
    Abstract: A compensation method devoid of operating voltage calibration, establishing fundamental linearity calibration table and inputting, and detecting the actual operating voltage is disclosed. The compensation method comprises the steps of: a) turning off a switch in a touch sensor system; b) initializing the touch sensor system and measuring a reference frequency outputted from a oscillator in the touch sensor system; c) turning on the switch and measuring a first frequency outputted from the oscillator; and d) deducting the first frequency from the reference frequency so as to obtain a frequency difference; and e) comparing the difference with a predetermined value, and judging based upon the difference if the touch sensor system is touched by a foreign object.

  • Patent number: 7955178
    Abstract: A damper assembly has a torque input member configured to be connected to engine crankshaft through a torque limit clutch. An output member has a hub configured to be mounted to a transmission input shaft. Damping springs operatively interconnects the input member and output member, enabling the input member and output member to rotate relative to each other at some angular displacements before the input torque from engine crankshaft is completely transmitted to transmission input shaft. The damping springs includes a series of long springs and a series of relatively short spring. The long springs compress before the short compress as the input member rotates relative to the output member.

  • Patent number: 7640409
    Abstract: Method and apparatus for data migration are described herein. In one embodiment, in response to data received from an application to be written to a first storage volume, the data is written to the first storage volume and a second storage volume substantially concurrently. When the first and second storage volumes are synchronized, a switchover is performed from the first storage volume to the second storage volume, such that subsequent data received from the application is written to the second storage volume, where writing the data to the first and second storage volumes and the switchover are performed without knowledge of the application. Other methods and apparatuses are also described.
