A quality assurance benchmark system tests a target executable application under load stress conditions over an extended period of time. The system has user-controlled parameters to benchmark performance, scalability, and regression testing before deploying the application to customers. The system includes a display processor and a test unit. The display processor generates data representing a display image enabling a user to select: input parameters to be provided to the target executable application, and output data items to be received from the target executable application and associated expected range values of the data items. The test unit provides multiple concurrently operating executable procedures for interfacing with the target executable application to provide the input parameters to the target executable application, and to determine whether data items received from the target executable application are within corresponding associated expected range values of the data items.

The present invention is an inexpensive, hand-held, and easy to operate millimeter-wave detection device that employs a non-imaging sensor which radiates a pulse of millimeter waves of a certain amplitude and frequency towards a target located at a distance from the detection device. The sensor receives pulses of millimeter waves that are reflected from the target and generates a voltage waveform that is characteristic mainly of the target material, while other parameters such as distance to the target are known. The processor of the detection device measures both the peak voltage and the rate of increase of the voltage until it reaches the maximum. Using an algorithm stored in a software module, the deviation between the rate of the voltage rise and the peak voltage is compared with values of similar parameters for a number of test targets made of different materials that were previously collected and stored in a calibration table in the memory of the device. A concealed object, e.g. a weapon, is positively identified when the measured voltage rise is found to be similar to one of the stored voltage rises. The circuitry of the detection device generates a visual and / or audio output to a display device which is indicative to the operator as to whether a concealed object is present and, if a match is found with the data in the calibration table, the nature of the concealed object is also displayed. In addition to the basic mode of operation described, various other operation modes can be employed with the detection device of the invention.

The present invention provides a mechanism for automatically setting the exposure time and gain of an electronic camera so that the acquired image has improved characteristics for the detection of a digital watermark. With the present invention the exposure time and gain of an electronic camera are set by first directing the camera at a test target with the camera's controls set to a default set of values. The system then calculates a histogram of the luminance values of the pixels in the image. Next characteristic values from the histogram such as the peak value, the centroid value, the RMS value, the median value, etc. are calculated. One or more of the characteristic values of the histogram are then applied as an index or pointer to values of pre-established settings that are stored in a table. Values from the table are used to set the exposure time and / or gain of the camera. In some embodiments, the variance of the luminance histogram is also measured and used to index data from the table.

A virtual tech rep system that can assist in reducing service call visits and customer complaints by readily analyzing image quality of an output image device, such as a copier or printer. The system generates a hardcopy test pattern output from the copier or printer and then scans the test pattern using either the platen of the digital copier or an external scanner to form a digital raster image. Test targets in the digital raster image are then determined using pattern recognition software and image quality analysis is then performed on the test targets based on the sensitivity of the human visual system. It is preferable that the image quality analysis is based on human vision systems rather than a direct comparison between original and printed images as many differences may go unnoticed by a human viewer whereas other types of differences may be readily noticed, even if only slight. The system optionally sends the test results and possibly part or all of the scanned test pattern to a service or diagnostic facility (remote or local) for further analysis when potential defects are identified. This process may be performed at start-up or automatically initiated after a predetermined number of operating cycles or hours of use have been attained.
