  • System for providing a calibrated clock and methods thereof
    Patent number: 7058149
    Abstract: A system and methods are provided for calibrating timing in a remote device to timing in a source device. The source device dictates timing signals to be generated in the remote device. A calibration routine is processed to calibrate timing in the remote device to timing in the source device. The source device provides a reference signal that dictates a period of time to the remote device. The remote device tracks a number of local clock cycles generated for the duration of the dictated period of time. The remote device then establishes a time base for translating a number of clock cycles dictated by the source device to a number of clock cycles generated within the remote device.

  • Method and apparatus for detecting a stall condition in a stepping motor
    Patent number: 6861817
    Abstract: Stepped rotary motion is imparted to the rotor of a stepping motor by alternately driving at least first and second coils which interact with a plurality of magnetic poles on the rotor. When each of the coils transitions from a driven to a non-driven state, the continued motion of the rotor causes a back electro-motive force to be generated in the coil. The electro-motive forces produced by the coils are rectified, integrated, and then compared with a threshold to determine if a motor stall condition exists.
