  • Patent number: 11805962
    Abstract: A dishwasher thermometer captures temperature data of temperature sensed within a dishwasher during a wash cycle. The dishwasher thermometer includes a wireless communication interface that transmits the captured temperature data to one or more of a server and a monitor device. When the captured temperature data indicates that the wash cycle did not achieve defined temperature threshold(s), an alert is generated at the server and/or the monitor device indicating that the wash cycle did not meet appropriate washing conditions. In embodiments, the temperature data may be accessible to a third party for certification of the dishwasher wash cycle.

  • Patent number: 6717360
    Abstract: An electroluminescent lighting device includes a elongate flexible body having an inner part and an outer part, an elongate multi-layer electroluminescent strip including a pair of co-extending conductive regions and extending along the inner body part, and a pair of conductive wires (36) extending along the inner body part for supplying electrical power to the strip. The wires are separated from the strip by at least a portion of the inner body part. A number of flexible contact elements are located at intervals along the inner body part for electrically connecting the conductive regions to the wires. Each contact element contacts with a respective conductive region and extends through the portion of the inner body part to contact a respective wire. An alternative device is formed with a single body extruded so as to encase an electroluminescent panel and a pair of rectangular cross-sectioned electrical conductors that are adhered continuously to conductive regions of the panel.
