  • Patent number: 11281266
    Abstract: A data capture device includes a housing supporting a window at a scan opening, a data capture module with a scanner field of view directed through the scan window, a heater controllable to heat the window, a non-contact temperature sensor with a sensor field of view directed at the scan window, an auxiliary temperature sensor, a humidity sensor, and a controller. The controller is configured to receive (i) a window temperature from the non-contact temperature sensor, (ii) an external ambient temperature from the auxiliary temperature sensor, and (iii) an external ambient humidity from the humidity sensor. The controller then determines a dew point according to the ambient temperature and the ambient humidity, and selects a power level for the heater based on a comparison of the window temperature and the dew point.

  • Patent number: 10933719
    Abstract: A vehicle air-conditioning apparatus is provided which is capable of efficiently eliminating or suppressing fogging of a window while comfortably heating a vehicle interior. A controller changes and executes a heating mode to let a refrigerant discharged from a compressor 2 radiate heat in a radiator 4, and a dehumidifying and heating mode to let the refrigerant discharged from the compressor radiate heat in the radiator and let the refrigerant absorb heat in a heat absorber 9. When the temperature of air blown out to the vehicle interior is not capable of reaching a target outlet temperature in the dehumidifying and heating mode, the controller actuates a window heater 35 heating a front window 30 and shifts to the heating mode.

  • Patent number: 6640570
    Abstract: In a vehicle air conditioner, an interior heat exchanger of a heat pump refrigerant cycle is disposed in an air conditioning case to heat and cool air passing therethrough. The air conditioning case has therein a bypass passage through which air flows to a downstream side while bypassing the interior heat exchanger. In a defogging mode, air mainly passing through the bypass passage is blown toward a windshield of the passenger compartment, and air mainly passing through the interior heat exchanger is blown toward a lower side in the passenger compartment. Accordingly, even by setting the heating capacity of the interior heat exchanger at a maximum degree, it can restrict a windshield from being fogged in the defogging mode.

  • Patent number: 5934988
    Abstract: A heating and air conditioning system for a motor vehicle includes a plenum supplied with air by each of a pair of variable speed blowers. A set of heating and air conditioning ducts extend from the plenum to the drivers side of the vehicle, and another set of heating and air conditioning ducts extend from the plenum to the passengers side of the vehicle. Accordingly, both the driver and the passenger can control the blower supplying air to the ducts on the corresponding side of the vehicle. A defrosting duct extends from the plenum to supply defrosting air to the windshield of the vehicle. One of the blowers normally supplies air to the defrosting duct, but the volume and velocity of air may be "boosted" by optional use of the other blower.

  • Patent number: 5331823
    Abstract: A heat pump type air conditioner for an automotive vehicle has a compressor to which an outer heat exchanger and a heat-radiating inner heat exchanger are connected through a three-way valve. The heat-radiating inner heat exchanger is connected to a heat-absorbing inner heat exchanger through an expansion valve. The heat-absorbing inner heat exchanger is connected to the compressor. During a cooling operation the three-way valve is set to lead the refrigerant from the compressor to the outer heat exchanger. During a heating operation the three-way valve is set to lead the refrigerant from the compressor to the heat-radiating inner heat exchanger while bypassing the outer heat exchanger.
