Abstract: A random weight item transaction system include a scale with label RFID tag functionality, service person RFID tag functionality and customer RFID tag functionality. A slicer in proximity to the scale may include service person and bulk food product RFID functionalities. The scale may make weigh transaction data available to a computerized checkout system via a communications link or via writing the information to the label RFID tag.

Abstract: A label printer for handling labels with RFID tags includes one or more advantageous features such as locating an RF encoder unit antenna in position to read and/or write to label antennas after the label antennas have exited a label output slot of the printer, providing light elements to indicate status of a read and/or write operation to a label RFID tag or a voiding step to void labels when a read and/or write operation is unsuccessful.

Abstract: An electronic tag having a customer attracting annunciator such as a light emitting element or sound element is provided. In one aspect, a tag constructed for sideward direction of lighting is provided. In another aspect, a battery free tag including a customer attracting annunciator which is energized with power derived from induced signals developed in the tag. In a further aspect, an annunciator of an electronic tag is controlled based upon signals output from an LCD display driver.

Abstract: A dishwashing machine and a method for washing ware therewith are disclosed. The machine includes a wash chamber, a tank for holding a cleansing liquid, a spray system including a selectively operable pump for spraying ware to be cleaned with liquid from the tank, and a heater for heating the liquid within the tank. The heater is regulated to maintain the liquid substantially at a first predetermined temperature whenever the pump is operating, and to maintain the liquid substantially at a second predetermined temperature greater than the first temperature whenever the pump is not operating.

Abstract: A control system and method of controlling a conveyor-type dishwasher is disclosed, with the dishwasher including a plurality of sequentially arranged work stations, each of the stations performing an operation on ware located therein such as washing, rinsing, drying and the like. A conveyor carries the ware into the dishwasher, past each of the stations, and out of the dishwasher. A sensor mounted at a reference point adjacent the conveyor near the entrance for ware to the dishwasher senses the presence of ware items on the conveyor as the items are carried past the reference point. Positional advance of the conveyor is monitored to define a current conveyor position and track movement of the items through the dishwasher.

Abstract: A magnetic coupling between the sample support shaft and the internal weighing mechanism of a weighing balance assembly is provided which permits transverse movement of the shaft when it or a sample supported by it are bumped or jarred. Generally, the internal weighing mechanism of a weighing balance is quite sensitive to the unavoidable bumping and jarring which occurs during the loading and unloading of a sample. Because the magnetic coupling permits movement of the shaft, no damaging forces or torques are transmitted to the weighing mechanism. The magnetic attraction between the shaft and coupling is sufficient to insure that the shaft remains in an upright position during normal operation.
