  • Publication number: 20100107323
    Abstract: A device such as a dental cuspidor or a dental delivery unit, with an electric field sensor, control circuitry, and a solenoid. The control circuitry is in electronic communication with the electric field sensor, and the solenoid is in electronic communication with the control circuitry. The electric field sensor has capacitive sensing and is operable to detect a change in capacitance. The control circuitry is operable to receive a signal from the electric field sensor indicative of a detected change in capacitance. The control circuitry is operable to actuate the solenoid in response to receiving the signal from the electric field sensor. A method is also provided.

  • Publication number: 20100109407
    Abstract: Dental devices with cylinders, trunnions, and limit switches, and a method are provided. The dental devices include a cylinder and a trunnion having a cavity and an outer surface. A portion of the cylinder is slidably mounted within the cavity of the trunnion, and a portion of the cylinder protrudes out of the trunnion. The limit switch is coupled to the outer surface of the trunnion, with the limit switch is operable to contact the cylinder. Separation of the limit switch and the cylinder causes actuation of the limit switch, and the actuation of the limit switch inhibits a downward movement of the device. Alternatively, the limit switch may be coupled to the portion of the cylinder that protrudes out of the trunnion, with the limit switch operable to contact the trunnion. As such, separation of the limit switch and the trunnion causes actuation of the limit switch.

  • Patent number: 6918398
    Abstract: A system and method of selectively extending a wash cycle duration of a warewasher beyond a set minimum duration provides suitable cleaning of wares while at the same time seeking to increase the number of wash cycles per unit time. A system and method for detecting water level in a wash chamber or other tank provides the ability to identify a progressively fouling electrode. A system and method of automatically priming one or more chemical feed lines of a warewasher is also described.

  • Publication number: 20030172663
    Abstract: A chiller includes a chilling compartment for receiving food products to be chilled and a chilling system for delivering chilled air to the chilling compartment during chilling operations. A controller effects operation of the chilling system and includes associated memory storing a plurality of food product data entries. Each food product data entry includes a food product name and at least one associated chilling operation setting for the food product. A user input device is associated with the controller. The controller is operable in conjunction with the user input device to permit a user to select a particular food product data entry such that the controller retrieves at least one chilling operation setting of the particular food product data entry for use in a subsequent chilling operation. The chiller may also include a label printing mechanism for printing chilling operation summary labels which can be applied to food product containers.

  • Patent number: 6550607
    Abstract: A warewasher jam detection system includes a conveyor drive arrangement having a drive motor assembly including a drive motor and an output shaft, and a slip clutch including an input side moved via the output shaft and an output side operatively connected for driving a conveyor. At least one sensor is provided for producing an output indicative of movement/non-movement of the output side of the clutch. Preferably the sensor is a non-contact type sensor such as a magnetic sensor, optical sensor or proximity sensor. A controller may be provided for receiving the sensor output signals and identifying a jam condition based upon the same, such that the controller can responsively stop the drive motor.

  • Patent number: 6311509
    Abstract: In a chiller, an apparatus and method for automatically identifying a temperature probe for use in a chilling operation is provided in order to reduce user error. In the place of manual selection by a user, automatic selection of the appropriate temperature probe is accomplished by comparing the temperature of the given temperature probe to a threshold temperature. An additional apparatus and method for filtering a displayed compartment temperature is provided to reduce user confusion. The responsiveness of the displayed temperature to temperature changes in the compartment is reduced when the compartment door is opened.
