Drapes for covering fluid heating devices having basins. Some drapes have a set of at least one positioning component trapped between the drape basin layer and the drape device layer by a set of bonds. The positioning component aligns the drape with the basin bottom. Optionally, the drape may have a low-slip film for basin contact and a non-slip film for at least a portion of the drape beyond the basin. Alternatively, a single layer drape may have a set of at least one positioning component bonded to the drape. Some drapes have basin-shaped sterile vented barrier with vents to allow the sterile vented barrier to be inserted into the basin and to vent air out of the basin. The heating system for the fluid heating device may interrupt electricity provided to a heating element when a temperature sensed at an air gap detector exceeds a high temperature setpoint.

A load board to which a socket is mounted is electrically connected to a tester. The load board includes a first optical communication unit capable of transmitting and/or receiving signals by optical wireless communication with an electronic component handling apparatus that presses a DUT against the socket.

A heating, ventilation, and air conditioning system includes a plurality of sensors including a first sensor configured to measure an outside air temperature of outside air, a second sensor configured to measure a return air temperature of return air, and a third sensor configured to measure a mixed air temperature of mixed air. The system also includes a controller communicatively coupled to the plurality of sensors. The controller is configured to determine that data from one of the plurality of sensors is unavailable and estimate the data from the one of the plurality of sensors based on data from other sensors of the plurality of sensors.

The present invention provides a temperature control method for a heating element, a night vision system calibration device and a system. The night vision system calibration device includes: a first housing, a heating element and a second housing covering the first housing. The heating element includes a heating area, a shape of the heating area being a shape of a target heating body used when a night vision system is calibrated. The second housing and the first housing form an accommodating cavity, and the heating element is disposed in the accommodating cavity. The second housing is provided with a through hole communicating with the accommodating cavity and adapted to the shape of the heating area, and the heating area is configured to emit infrared radiation through the through hole. In the temperature control method for a heating element, the night vision system calibration device and the system provided in the present invention, a target heating body for a night vision system used when the night vision system is calibrated may be provided, so that the night vision system after fault repair can be calibrated based on the target heating body, thereby improving the accuracy of the night vision system after the fault repair.
