In one embodiment, a part of the image containing safety critical information is segmented into smaller areas and the luminance of pixels in each segmented area is compared with a threshold brightness level and a threshold darkness level. A histogram for each area is generated and compared with a reference.

Abstract: Interfacing between radio units in a base station in a mobile communication system uses a common public radio interface CPRI for streaming IQ data samples arranged in lanes. A separate serial interface sRIO is now additionally used for transferring selected data samples arranged in packets, the selected samples corresponding to selected lanes streamed between other radio units via the common public radio interface. In the radio unit, the selected data samples are arranged in packets to be transmitted via the serial interface, and, vice versa, the selected data samples arranged in packets received via the serial interface are arranged in lanes. A system timer coupled to the CPRI generates a timebase for controlling the sRIO interface in order to have it synchronized. Advantageously the data sample transfer capacity of the streaming CPRI interface is extended using the packet based serial interface.

Abstract: An on-board trimming circuit suitable for trimming an accelerometer provides offset trim and gain trim modules for determining correct trim codes for subsequent programming into the trimming circuit. The correct trim codes may be determined by comparing sensor outputs which have been adjusted by successive trim codes, with a reference voltage in a comparator until the comparator toggles or by using a successive approximation technique. The reference voltage is supplied form a tap of a feedback resistance divider circuit which forms a part of an on-board voltage reference generator which may be used to provide a full scale reference for an analog to digital converter which converts a sensor output voltage into a digital signal. Using these reference voltages significantly lessens the impact of any offsets inherent in the voltage reference generator on the trimming process.
