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: 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: An occupant detection system includes a state detection unit that detects a state of an object, a detection position changing unit that changes a position of a detection region, the detection region being a region in which state is detected by the state detection unit, and a controller that controls an operation of the detection position changing unit. In this occupant detection system, a position of the detection region is set to a predetermined initial position during a period of time from when a start switch provided in the vehicle is turned off until when the start switch is turned on.
