  • Patent number: 8348387
    Abstract: The pagewidth inkjet printer provides for simultaneous printing across a horizontal portion of a sheet of paper, as opposed to horizontal scanning of a conventional inkjet printer. The pagewidth inkjet printer includes a platen for incrementally translating a page of paper and a controller for selectively driving rotation of the platen. A housing is mounted adjacent to the platen and is fixed with respect thereto. A plurality of print heads are mounted within the housing. Each print head has a plurality of nozzles for selectively ejecting ink, and each nozzle is adapted for ejecting a distinct color of ink. The plurality of nozzles of each print head are aligned in a direction parallel to a direction of translation of the page of paper. The plurality of print heads are arrayed and aligned linearly along a direction orthogonal to the direction of translation of the page of paper.

  • Patent number: 8352774
    Abstract: The inter-clock domain data transfer FIFO circuit provides a circuit that transfers data between two clock domains of unrelated frequencies. The gate count is kept relatively low, thereby allowing data transfer between the two clock domains at one data item per cycle of the lower of the two frequencies. Depending on the frequency difference between the data producer and consumer, the initial latency could be as low as a fraction of a cycle and no more than two cycles of the consumer's clock. The operation of the data transfer FIFO circuit has been verified using gate-level simulations for several ratios of clock frequencies.

  • Patent number: 8347695
    Abstract: The meat tenderness tester is a hand held tool that includes a rotatable elongate shaft, which can be stuck into meat at a precise depth and rotated by a motor disposed in the tool. The shaft has various configurations that allow it to be inserted into the meat and withdrawn without destroying the meat being tested. Fin-like members disposed on the shaft create a measurable resistance to rotation that is measured by a torque sensing part of the motor. A digital display on the housing body reads out this mechanical resistance (torque) in a calibrated measurement of the shear forces encountered by the rotating shaft; the measurement indicating a degree of tenderness of the meat cut being tested. The shaft has a tapered, pointed end that allows it to be inserted and withdrawn without damaging the meat product under test.
