Abstract: An optical sensor includes pixels. Each pixel has a photodetector. A readout circuit performs a process over an exposure time where the photodetector is connected to a reverse bias voltage supply to reset a voltage across the photodetector, and the photodetector is disconnected from the reverse bias voltage supply until that the voltage across the photodetector decreases in response to received ambient light. An ambient light level is then determine an based on a number of times the voltage across the photodetector is reset over the exposure time.

Abstract: An imaging device includes a detector array and an aperture disposed along an optical path, with an array of filter elements disposed in the optical path therebetween. The detector array has a plurality of detector elements that are sensitive to a wavelength spectrum of interest, such as, for example, the visible spectrum and/or the infrared (IR) spectrum. Each filter element is configured to filter out energy within the wavelength spectrum of interest that is in a wavelength band of interest to form filtered energy within the wavelength spectrum of interest that is outside the wavelength band of interest. The filtered energy is passed by each filter to at least one corresponding detector element, which generates one or more detector values based on the received energy. The detector values may be processed to determine an intensity value for the wavelength band of interest.

Abstract: A vehicle is disclosed. The vehicle includes a first indicator light associated with a first function or a first state of the vehicle (e.g., a brake light), and circuitry coupled to the first indicator light. The circuitry is configured to cause the first indicator light to emit light when the vehicle is performing the first function or is operating in the first state, and detect an amount of light incident on the first indicator light. Thus, the indicator light can be used to detect incoming light to perform various vehicle functions (e.g., automatically dimming mirrors based on the incoming light) without the need for a dedicated light sensor.

Abstract: The invention is directed to a method for measuring an internal thread of a workpiece with a coordinate measuring apparatus and a CCD or CMOS sensor. The sensor records at least two images of a section of the internal thread and the recording conditions for the two images are modified. The data from these two recorded images are used to establish the position, orientation, core diameter and/or the pitch of the internal thread. The invention is also directed to an arrangement for measuring an internal thread of a workpiece and includes a coordinate measuring apparatus and the CCD or CMOS sensor in accordance with the above method.
