  • Patent number: 7022956
    Abstract: A retrospectively-fitted multi-configurable microwave oven accessory the purpose of which is to provide an automated stirring capability of foodstuffs by use of the internal rotary plate of a microwave oven to provide a relative motion of the foodstuff and which is configured from a roof rail, a series of roof fittings and a series of stirring implements and where necessary may employ a food receptacle securing method. The device is shown at FIG. 7 of the attached drawings.
    Type: Grant

  • Patent number: 6768342
    Abstract: A surfing pipelined logic circuit has a timing system which provides a timing signal sequentially to each of a plurality of logic blocks. The logic blocks are connected in a series and may have a linear configuration or a ring configuration. Each of the logic blocks has a latency which is variable in response to the timing signal. When the timing signal is not present, the latency is longer than a timing delay which occurs between the timing system applying the timing signal to the logic block and the timing signal applying the logic signal to a next one of the logic blocks. When the timing signal is present, the latency is shorter than the timing delay. The timing system may comprise a timing path carrying timing signals. The timing path may have a number of nodes connected to control inputs of corresponding ones of the logic blocks.

  • Publication number: 20040025706
    Abstract: A devise which makes use of the relative motion of a rotary plate inside a microwave oven for stirring food stuffs in a microwave oven so that an even heat distribution throughout the food is facilitated. The device consists of a Roof-Rail, a Roof-Fitting, and Stirring Implements and where necessary may employ a food receptacle securing method. The device is shown at FIG. 7 of the attached drawings.
