Abstract: A testing apparatus and method consisting of multiple measurement modules having one or more circuit assembly boards, two data/power connectors, and a target connector. Signal data is accessed from 1-128 target signal sources and sampled through two separate analog to digital channels. An on-board microcontroller controls signal selection and data sampling rates and also provides for transfer of recorded data over a USB bus to a host computing device. Using a proper testing application loaded onto the host computing device, each module can be commanded to access and store representative data from a number of signal sources at each target system. Each module is connected to other modules and a host computing device to create a complete self-powered test access environment. The interconnectivity of the system makes diagnosing electronic component failures in an armored vehicle, such as a tank, much easier than prior manual fault isolation procedures.

Abstract: A small and compact infrared scene projector allows for projection of infrared images from a variety of sources. The unit utilizes an external power supply to reduce the weight of the unit and has several input pathways such as an integrated RS-232 serial port and a video port for receiving RS-170 formatted video signals. The projector uses a digital signal processor to control its internal electronics and for on-board generation of pre-programmed infrared images. A processor electronics card and a scene generator electronics card communicate internally to generate images and to control a thermoelectric cooling device mounted to a semiconductor infrared emitter array to project flicker free, high resolution infrared images. Optics in the form of an interchangeable lens or a mirrored collimator allow for projection of a generated image onto a test object.
