  • System and method for generating a delayed clock signal of an input clock signal
    Patent number: 7675339
    Abstract: A system and method for generating a delayed clock signal of an input clock signal involves selectively delaying the input clock signal to produce the delayed clock signal based on the duty cycle of the input clock signal and the duty cycle of a logic signal derived from a logic operation of the input clock signal and the delayed clock signal.

  • High impedance current mirror with feedback
    Patent number: 7463014
    Abstract: A current supply includes a current mirror arrangement having a feedback circuit. The current supply includes a current mirror input stage connected to a constant current source providing a reference current; a current mirror output stage providing an output current substantially mirroring the reference current; and a feedback circuit feeding back to the current mirror input stage a feedback signal representing perturbations in the output current to cause the output current to more accurately mirror the reference current. In one embodiment, a dummy current mirror output stage substantially mirrors the reference current, and the feedback circuit receives a signal from the dummy current mirror output stage, and in response thereto, supplies the feedback signal to the current mirror input stage to cause the output current to more accurately mirror the reference current.

  • Electronic device having an interactive display screen
    Patent number: 7053883
    Abstract: An electronic device (9) has an interactive screen display (27) which is interactive with a stylus (10). The electronic device (9) has an actuator (30) associated with an engagement member (18) of a housing (16) of the device. The actuator (30) is actuated when the stylus (10) engages the engagement member (20) to provide an activation signal indicative of the stylus engaging or disengaging the engagement member (20). As a result, the electronic device (9) or display screen is inactivated or activated when the stylus (10) engages the engagement member (20).
