  • Patent number: 11345166
    Abstract: 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.

  • Patent number: 11325400
    Abstract: 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.

  • Patent number: 11231669
    Abstract: 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. 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 to apportion a measure of the first power grant to the second power grant rather than provide the measure of the first power grant to the first heater system if a print substance density is within a selected print substance density threshold and the first load request is within a selected load threshold.

  • Publication number: 20220019274
    Abstract: 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.

  • Publication number: 20220009250
    Abstract: In some examples, a system can include: a heating device, a Proportional Integral Derivative (PID) controller and a switching mechanism to selectively enable transmission of signals to the heating device based on a real time temperature in proximity to the heating device, wherein the PID controller is to continuously output pulse width modulation (PWM) signals independent of selective transmission of signals by the switching mechanism.

  • Publication number: 20210331461
    Abstract: In some examples, a media conditioner includes a conveying component to convey a sheet of printable media, a first heating element to heat a first portion of the conveying component, a second heating element to heat a second portion of the conveying component, and a controller. The controller is to provide a variable first power level to the first heating element and a variable second power level to the second heating element to cause the first and second heating elements to generate heat. In addition, the controller is to determine a first parameter based on the first power level and to determine a second parameter based on the second power level. The controller is also to produce a result indicator based on a result of a comparison between the first parameter and the second parameter.

  • Publication number: 20210245494
    Abstract: 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. The processor may also borrow, from the second period, a portion of a second power event of the second set of power events and may apply the borrowed portion of the second power event to a first power event of the first set of power events during the first period to remove the first zero power event from the first period.

  • Patent number: 10947073
    Abstract: In some examples, velocity and torque based media motor control may include ascertaining a velocity and torque for a feed roller motor associated with a feed roller, and ascertaining a velocity and torque for a drive roller motor associated with a drive roller that is to receive media from the feed roller. Further, velocity and torque based media motor control may include determining whether the torque for the drive roller motor is greater than a torque target. In response to a determination that the torque for the drive roller motor is greater than the torque target, the torque for the drive roller motor may be reduced to the torque target, and the torque for the drive roller motor may be maintained at the torque target.

  • Patent number: 10946674
    Abstract: A sequence of loads within a system is determined during each of multiple time windows based on a determination of each load's temperature to a target value. The sequencing of the loads involves a determination as to whether the length of each time window is long enough to permit all of the loads to be sequentially activated in order to have their temperatures approximate the corresponding target temperatures. In some cases, the sequence of the loads is determined to be one that results in a monotonically changing power profile.
