Publication number: 20230021550Abstract: A control system for controlling an adjustable output voltage provided to a heater includes a controller configured to determine an input parameter based on an electrical characteristic of the heater, where the heater includes a resistive heating element that is operable to emit heat and as a sensor. The controller is further configured to determine an output voltage for the heater based on the input parameter and a desired setpoint, and to transmit a signal to a power converter to generate the output voltage. The desired setpoint is based on an operational state of the heater, and the input parameter includes data indicative of a temperature of the resistive heating element that is determined based on the electrical characteristic.Type: ApplicationFiled: September 30, 2022Publication date: January 26, 2023Applicant: WATLOW ELECTRIC MANUFACTURING COMPANYInventors: Stanton H. BREITLOW, John F. LEMKE, James HENTGES, Keith Douglas NESS, Eric ELLIS, William BOHLINGER, Matthew YENDER, Dean R. MCCLUSKEY

Publication number: 20200256899Abstract: A control system includes a power converter being a step-down voltage converter and including a power switch. The power converter is operable to generate an adjustable output voltage and includes a sensor circuit configured to measure at least one of a voltage and an electric current of the heater. The control system includes a controller connected to the power converter and the sensor circuit. The controller is configured to determine an input parameter based on the at least one of the voltage and the electric current. The input parameter is indicative of a temperature of the heater. The controller is configured to set the output voltage applied for the heater based on the input parameter and a desired setpoint. The desired setpoint is based on an operational state of the heater. The controller is configured to operate the power switch of the power converter to generate the output voltage.Type: ApplicationFiled: April 29, 2020Publication date: August 13, 2020Applicant: Watlow Electric Manufacturing CompanyInventors: Stanton H. BREITLOW, John F. LEMKE, James HENTGES, Keith Douglas NESS, Eric ELLIS, William BOHLINGER, Matthew YENDER, Dean R. MCCLUSKEY

Patent number: 9196513Abstract: A system and method is provided. In one aspect, the system and method may calculate a time period for each mode of a plurality of modes. The system and method may index through each mode for the corresponding time period to provide power to the plurality of thermal elements according to the mode. In another aspect the system and method may index sequentially through each mode of a plurality of modes and apply power to an indexed mode while measuring an electrical characteristic of the thermal elements for the indexed mode.Type: GrantFiled: August 30, 2012Date of Patent: November 24, 2015Assignee: WATLOW ELECTRIC MANUFACTURING COMPANYInventors: Philip S. Schmidt, Cal T. Swanson, John F. Lemke

Publication number: 20100030592Abstract: A mobile device includes a light source and a light source controller. Data to be transmitted to a point of sale or point of use is obtained by the mobile device, and the light source controller controls the light emitted by the light source to emit light in a blinking pattern that simulates light that would be reflected to a laser scanner when a laser scanner is reading a barcode corresponding to the data to be transmitted. The light, emitted in the blinking pattern, is detected by a laser scanner which then decodes the data represented by the blinking pattern to obtain the data transmitted from the mobile device.Type: ApplicationFiled: July 30, 2009Publication date: February 4, 2010Applicant: Mobilocity Solutions LLCInventors: Geoffrey D. Evans, Gail L. Cannon, John F. Lemke, Alexander E. Osipov
