Patent number: 11852995Abstract: According to examples, an apparatus may include a processor that may identify a first period for a heated system, the first period including a first set of power events and a first zero power event for the heated system and may identify a second period for the heated system, the second period including a second set of power events and a second zero power event for the heated system.

Patent number: 11493866Abstract: In some examples, a system is disclosed that includes a roller assembly for a printer. The roller assembly includes a pressure roller, a belt coupled, a drive assembly to rotate the pressure roller and to urge the pressure roller into the belt, a heater to apply heat to the belt, and a temperature sensor to detect a temperature of the belt. In addition, the roller assembly includes a controller to increase a pressure applied to the pressure roller from a first to a second pressure in pressure in response to a temperature of the belt being greater than or equal to a first temperature threshold. Also, the controller is to initiate an advance of a print media to contact the belt in response to the temperature of the belt being greater than or equal to a second, higher temperature threshold.Type: GrantFiled: June 8, 2018Date of Patent: November 8, 2022Assignee: Hewlett-Packard Development Company, L.P.Inventors: Jody L Clayburn, Lorraine T Golob, Daniel James Magnusson, Brooke Hoyer

Patent number: 11345166Abstract: Power allocation in printing devices is disclosed. Independent load requests are received from printing device heater systems. A first load request is received from a first heater system and a second load request is received from a second heater system. Power grants are allocated based on a general power arbitration of a power source in response to the independent load requests. The power grants include a first power grant based on the first load request and a second power grant based on the second load request. The power grants are adjusted based on a contextual printing condition. The power grants are adjusted to apportion a measure of the second power grant to the first power grant rather than provide the measure of the second power grant to the second heater system if a print substance density is outside a selected print substance density threshold.Type: GrantFiled: August 31, 2018Date of Patent: May 31, 2022Assignee: Hewlett-Packard Development Company, L.P.Inventors: Duane A Koehler, Robert Yraceburu, Daniel James Magnusson

Patent number: 11325400Abstract: According to examples, a heated system may include a heat generating device, a temperature sensor to detect temperature in the heated system, and a controller. The controller may store temperatures detected by the temperature sensor over time and based on a determination that the temperature in the heated system has reached a predefined temperature value, stop application of power to the heat generating device. The controller may also calculate a rate of change of the stored temperatures corresponding to a predefined period of time prior to the application of power to the heat generating device being stopped, may determine a seeding value for a control mechanism of the heat generating device based on the calculated rate of change, and based on aa determination that a predefined condition has occurred, control the control mechanism to apply power to the heat generating device beginning with the determined seeding value.Type: GrantFiled: July 13, 2018Date of Patent: May 10, 2022Assignee: Hewlett-Packard Development Company, L.P.Inventors: Robert Yraceburu, Daniel James Magnusson

Patent number: 11231669Abstract: Power allocation in printing devices is disclosed. A first load request is received from a first heater system having a first thermal time constant and a second load request is received from a second heater system having a second thermal time constant.

Publication number: 20220019274Abstract: In some examples, a system identifies a plurality of time periods in which a time period includes a power event and a zero power event. The system tracks a cumulative error value that is adjusted based on elimination of a power event or elimination of a zero power event in the time period. The system determines a value of a first term if a power event in the time period is eliminated, and determines a value of a second term if a zero power event in the time period is eliminated, and based on the cumulative error value, the value of the first term, and the value of the second term, decides between eliminating the power event in the time period and eliminating the zero power event in the time period.Type: ApplicationFiled: December 14, 2018Publication date: January 20, 2022Applicant: Hewlett-Packard Development Company, L.P.Inventors: Robert Yraceburu, Duane A.
