A detection system that includes: an image capture apparatus configured to capture images of a scene located in the passenger compartment and a projection system configured to project structured light on the scene. The projection system has at least one projection device, each projection device being separate from the image capture apparatus so as to be mounted in the passenger compartment while being offset relative to the image capture apparatus. Each projection device is configured to project at least one structured light pattern. The detection system further includes an electronic control unit configured to analyze images captured using the image capture apparatus during the projection of one or several structured light pattern(s).

An optical sensor module for sensing a face of a person for user identification and authentication, where a face illumination module is provided to use an array of face illumination light sources arranged in a regular array pattern to produce illumination light which may be invisible light such as infrared light and an optical diffraction element that is located to receive illumination light beams from the face illumination light sources and to transfer each illumination light beam from each face illumination light source in the array into a patterned light beam containing illumination light spots.

A method for collecting and processing terahertz spectral imaging data includes: scanning an object to generate terahertz spectral data having a hyper- or low-spectral resolution respectively at a plurality of pixel points; collecting the terahertz spectral data and recording coordinate data of each pixel point, thereby obtaining a mixed data including a hyper-spectral data and a low-spectral data corresponding to different pixel points; constructing a hyper-spatial and low-spectral imaging data-cube from the mixed data; extracting a hyper-spectral data-set from the mixed data; and reconstructing a hyper-spatial and hyper-spectral imaging data-cube from the hyper-spatial and low-spectral imaging data-cube based on the hyper-spectral data-set. A terahertz spectral imaging apparatus is further provided.

This invention provides a system for detecting body temperature with temperature compensation. The system includes: a first sensor, detecting some objects in an area and performing an identifying procedure; a second sensor, measuring temperatures of those objects and outputting several ambient temperatures and body temperatures, wherein the ambient temperatures and the body temperatures are identified as non-body temperatures and body temperatures by the identifying procedure; and a central processing unit, receiving and averaging the ambient temperatures to produce a current temperature, and reading a reference temperature, comparing the current temperature with the reference temperature to produce a compensation, performing operations for the compensation and the body temperatures to output some actual body temperatures.

An occupant monitoring device for a vehicle includes an imager, a display, and a determiner. The imager is configured to image a cabin of the vehicle to monitor conditions of occupants in the vehicle. The display is configured to display a screen to be viewed by the occupants in the vehicle. The determiner is configured to determine the conditions of the occupants in the vehicle by using captured image data obtained by imaging each of the occupants by the imager while the screen is displayed on the display. A panel configured to display the screen of the display has an outer edge outside a display area of the screen. The imager is disposed on a back of the outer edge of the panel of the display.

Signal detection and recognition employees coordinated illumination and capture of images under to facilitate extraction of a signal of interest. Pulsed illumination of different colors facilitates extraction of signals from color channels, as well as improved signal to noise ratio by combining signals of different color channels. The successive pulsing of different color illumination appears white to the user, yet facilitates signal detection, even for lower cost monochrome sensors, as in barcode scanning and other automatic identification equipment.
