Abstract: Embedded processor-based self-test and diagnosis using the compressed test data is described for ICs having on-chip memory. Techniques for compressing the test data before the compressed test data is transferred to a device under test (DUT) are also described. A modified LZ77 algorithm can be used to compress strings of test data in which don't care bits are handled by assigning a value to the don't care bits according to a longest match in the window as the data is being encoded. The compressed test data can be decompressed at the DUT using a software program transferred by the automated test equipment (ATE) to the DUT with the compressed test data. Decompression and diagnostics can be carried out at the DUT using an embedded processor and the on-chip memory. Results from the diagnostics can be read by the ATE.

Abstract: The present invention relates to a signal processor, and more particularly, to systems, devices and methods of using a comprehensive sensor fusion algorithm to integrate sensor data collected by accelerometers, gyroscopes and magnetometers. The signal processor dynamically applies a Complementary Filter to merge a rotation based gyro output and a FQA output that is obtained by combining acceleration rates and magnetic field magnitudes. Therefore, motion information is derived to generate a motion control signal. Such a comprehensive sensor fusion algorithm significantly reduces the complexity of computation, and the power and area overhead is controlled. As a result, the signal processor may be implemented based on local computation capability of a sensor system, and its integration within such a sensor system is made possible without relying on an external microprocessor.

Abstract: A non-contacting deviation measurement system projects a first line and a second line upon a surface of an object. The projections of the first line and second line are arranged to overlap at an intersection line oriented at a nominal location such that when the surface is oriented at the nominal location, the intersection line appears on the surface. As the location of the surface deviates from the nominal location, the first line and second line as projected upon the surface move away from one another. The distance between the lines may be used to calculate the deviation from the nominal location. The deviation calculated may be compared to a predetermined maximum allowable deviation.

The microprocessor control unit receives power from a battery. An exemplary embodiment detects an operating voltage provided to the microprocessor control unit by a supplemental power reservoir after removal of the battery, stores information corresponding to a value of the operating voltage in a nonvolatile memory, repeats the detecting and the saving information as the operating voltage decays in response to a discharge of the supplemental power reservoir, and determines the actual minimum operating voltage for the microprocessor control unit based on a last one of the stored information corresponding to the value of the operating voltage. A learned critical voltage value is based upon the defined actual minimum operating voltage.
