  • Patent number: 6760179
    Abstract: A method and apparatus for unlatching a VCM in a disc drive is provided in which a determination is made if the VCM is stationary. A first unlatch current pulse that has a first amplitude and first width is applied to the VCM if the VCM is found to be stationary. An incremented unlatch current pulse is then applied to the VCM if the VCM is found to be stationary after application of the first unlatch current pulse. The incremented unlatch current pulse has at least one of an amplitude and a width that is greater than at least one of the corresponding first amplitude and the first width of the first unlatch current pulse.

  • Patent number: 5633076
    Abstract: A method is disclosed for the production of a transgenic bovine or a transgenic bovine embryo comprising obtaining an ovum from bovine ovaries, maturing the ovum in vitro, fertilizing the mature ovum or ova in vitro to form a zygote, introducing a transgene into the zygote in vitro and maturing the zygote to a preimplantation stage embryo in vitro. To produce the transgenic bovine, the embryo is transplanted into a recipient female bovine, wherein the female bovine gestates the embryo to produce a transgenic bovine.

    Abstract: A frame phase aligner for a transfer system includes selection circuitry for selecting one of a plurality of input signal groups, which include data, a clock signal, an inverse clock signal and a frame synchronous signal, received from outside of the frame phase aligner. A selection signal generator provides the selection circuitry with a selection signal according to write data input from outside of the frame phase aligner, so that the selection circuitry selects one of the plurality of input signal groups according to the selection signal indicative of the setup environment of the transfer system. A control signal generator generates control clock signals and a retiming control signal in order to demultiplex selected data of the input signal group selected. A demultiplexer demultiplexes data selected to form parallel data, retimes the parallel data, and controls the phase of the parallel data according to the control retiming signal and the control clock signals output from the control signal generator.
