Abstract: A warewasher for washing wares including a housing defining an internal space with at least one spray zone for washing wares. The housing includes an opening defined in part by a lower shelf. A liquid delivery system provides a spray of liquid within the spray zone. An access door has a vertically hinged connection to the housing to provide an open configuration that allows user access to the spray zone and a closed configuration that inhibits user access to the spray zone. The access door includes a threshold seal member at the bottom of the access door. The threshold seal member includes a lower sealing portion that mates with an upper surface of the shelf to provide a lower seal extending laterally along a width of the access door, and an inner sealing portion that cooperates with an inner edge the shelf to provide an inner seal extending laterally along the width of the access door. The inner seal located nearer the spray zone than the lower seal.

Abstract: A warewash machine includes a multi-position splash guard enabling multiple machine configurations in which undesired overspray is reduced or eliminated. A drip flange may also be provided to increase the amount of water that impinges upon wares.

Abstract: An apparatus for providing an output signal for selectively controlling movement of a visual pointer on a display screen is disclosed. A plurality of solid state capacitive sensor switches are arranged in a two-dimensional array. Each of the switches is actuable in response to the positioning of a finger of a user to an on/off state. A control unit responsive to the on/off state of each of the plurality of solid state capacitive sensors generates an output signal that selectively controls the movement of the visual pointer.

Abstract: An acupressure device for use on a selected skin surface portion of a human body. The device comprises a thin flexible base sheet having a first side, a second side and a margin. The margin has at least a portion of its length shaped as an orienting margin, wherein the orienting margin is shaped to correspond to a shape on, or adjacent to, the selected skin surface portion when the base sheet is placed on the selected body surface. An adhesive layer is on the first side of the base sheet that is suitable for attaching the base sheet to the selected skin surface portion. There is at least one bead on the adhesive layer suitable for positioning against the selected body surface that will provide acupressure to at least a portion of the selected body surface when the acupressure patch is placed against the selected body surface.

Abstract: A fingertip-operated solid state capacitance switch detects a capacity change that is induced by the physical contact of an ungrounded fingertip to an external dielectric surface of the solid state switch. The input and output of a solid state signal-inverting amplifier are respectively connected to two relatively large and ungrounded capacitor plates that are associated with, but electrically isolated from, the switch's external dielectric surface. An ungrounded fingertip forms a third capacitor plate on the switch's external surface. The solid state amplifier detects the presence of a fingertip on the switch's external surface by way of a change in capacitance within a compound, three plate, capacitor that includes the two ungrounded capacitor plates and the ungrounded fingertip that is resident on the switch's external surface.

Abstract: The invention is directed to a circuit arrangement for rapid sortation or selection of at least three digital values according to rank. In the circuit arrangement, the input channels are directly interconnected via digital comparators or arithmetic logic units. The outputs of the digital comparators or arithmetic logic units are connected to a gate-logic circuit or a ROM table controlling data selectors for the transfer of selected values or a network of data selectors for the sortation of all input values.

Abstract: The invention is directed to methods and circuit arrangements for video-rapid determination of the median of an evaluation window. In a first step, the gray values of one column of the evaluation window are transferred in accordance with their relative rank to window line memories; in a second step, selection circuit arrangements select gray values in parallel from all window line memories according to their rank relative to one another. Only these selected gray values are then processed in subsequent steps by processing circuit arrangements.
