  • Patent number: 10072862
    Abstract: An HVAC system includes an evaporator coil and a metering device. The HVAC system includes a variable-speed circulation fan and a condenser coil fluidly coupled to the metering device. A variable-speed compressor is fluidly coupled to the condenser coil and the evaporator coil. A controller is operatively coupled to the variable-speed compressor and the variable-speed circulation fan. A second temperature sensor is disposed in an enclosed space. The second temperature sensor measures temperature of the enclosed space and transmits the temperature of the enclosed space to the controller. The controller determines if the temperature of the enclosed space is below a minimum threshold. Responsive to a determination that the temperature of the enclosed space is below the minimum threshold, the controller modulates at least one of a speed of the variable-speed compressor and the variable-speed circulation fan to lower a discharge air temperature.

  • Patent number: 9840075
    Abstract: A method of printing an image with a printhead having spatially offset groups of drop ejectors, each group having a plurality of drop ejectors that are aligned substantially along a scan direction, includes enabling simultaneous firing of drop ejectors that are corresponding members of a first set of groups. Drop ejectors within each group of the first set are sequentially fired until each member of each group has had opportunity to fire. Corresponding drop ejectors of a second set of groups are simultaneously fired, and drop ejectors within each group of the second set are sequentially fired. Any additional groups of drop ejectors are likewise fired until all drop ejectors have had opportunity to fire during a first stroke. Drop ejectors are fired in subsequent strokes similar to the first stroke as the recording medium is moved relative to the printhead along the scan direction until printing is completed.
