  • GENERIC FLEXIBLE TIMER DESIGN
    Publication number: 20090045847
    Abstract: One embodiment of the present invention sets forth a set of three building block circuits for designing a flexible timing generator for an integrated circuit. The first and second building blocks include delay elements that may be customized and fine-tuned prior to fabrication. The third building block may be tuned prior to fabrication as well as after fabrication. The three building blocks may be incorporated into a modular architecture, enabling designers to easily generate well-characterized, flexible, generic timer circuits.

  • Low power single-rail-input voltage level shifter
    Patent number: 7463065
    Abstract: An apparatus includes a single-rail input connected to a low-voltage domain and a voltage-transition circuit connected to the single-rail input. The voltage-transition circuit is configured to convert a voltage of the low-voltage domain received via the single-rail input to a voltage of the high-voltage domain.

  • Discretely Adjustable Pipettor
    Publication number: 20080260592
    Abstract: A pipettor is provided of discretely adjusting the volume of fluid transferable by the pipettor in a pipetting operation. One or multiple piston assemblies, comprising pistons detached from the actuator of the pipettor, resilient members that urges the pistons toward initial positions, and independent adjusting mechanisms, such as slide-and-lock, facilitate discrete adjustments of the pipetting volume. The pipettor affords the operator to expediently adjust the pipetting volume, and to conveniently operate the pipettor using only one hand.
