    Abstract: An occupant detection system may detect a state of an occupant in a vehicle compartment. The occupant detection system may photograph the vehicle compartment and generate an image. The occupant detection system may change an attitude in order to change a position of an imaging region within the vehicle compartment. The occupant detection system may estimate the attitude based on information included in the image and control an operation based on the estimated attitude. The sensor may be provided by an infrared temperature sensor. The image may be provided by a thermal image showing a temperature distribution of the vehicle compartment. The occupant detection system may store a correspondence relationship between a position of a specific temperature boundary included in the thermal image and the attitude. The occupant detection system may estimate the attitude based on the correspondence relationship.

    Abstract: A humidity detector a humidity sensor detecting a relative humidity of an air inside a sensor case housing the humidity sensor. The humidity detector has an air volume obtaining section, a flow direction obtaining section, a setting section, and a correction section. The air volume obtaining section obtains air volume information correlated with an air volume of the air flowing around the humidity sensor. The flow direction obtaining section obtains flow direction information correlated with a flow direction of the air flowing around the humidity sensor. The setting section sets correction factors configuring a dynamic compensator based on the air volume information and the flow direction information. The dynamic compensator compensates for a response delay of the humidity sensor. The correction section corrects a detection value, which is detected by the humidity sensor, by using the dynamic compensator to obtain the relative humidity of the air.

    Abstract: When a control device of a motor controller simultaneously rotates a first DC motor and a second DC motor by controlling a first circuit, a second circuit and a third circuit, the second circuit is shared. Further, the control device controls each of switch elements of the shared second circuit by using pulse-width modulation. Accordingly, the drive of the first DC motor and the second DC motor can be controlled with high accuracy by the change of a duty ratio of each of the switch elements of the shared second circuit.

    Abstract translation: 当电动机控制器的控制装置通过控制第一电路，第二电路和第三电路同时旋转第一直流电动机和第二直流电动机时，共享第二电路。 此外，控制装置通过使用脉冲宽度调制来控制共享的第二电路的每个开关元件。 因此，可以通过改变共享的第二电路的每个开关元件的占空比来高精度地控制第一直流电动机和第二直流电动机的驱动。
