摘要： The head mounted digital viewing system includes a sensor system, positionable substantially directly in front of the eyes of the user. The sensor system provides sensor video data. An image processing system is configured to receive the sensor video data. The image processing system modifies the sensor video data and provides display video data. A display system is positionable substantially in front of the eyes of the user. The display system is configured to receive the display video data and provide a display image to at least one eye of the user. The display system is positionable between the sensor system and at least one eye of the user. The line of sight of the sensor system and the display system are substantially aligned with the line of sight of at least one eye of the user. The sensor system and the display system are mechanically separate from each other and mechanically aligned with each other.

摘要： A method of operating an optical system is described. An image is detected. A digital image signal based on a spatially varying luminance level of the detected image is received. Horizon data, separate from the digital image signal, indicating the position of a horizon where a sky is adjacent the horizon, is received. The position of the horizon is determined based on the received horizon data. A fused image signal is provided based on the received digital image signal and the determined position of the horizon where a sky region indicative of the sky is provided with an enhanced color fused with the varying luminance level of the detected image. A full color display displays a fused image based on the fused image signal. A corresponding optical system is also described.

摘要： The present invention includes an image processing system with several data compression processing units connected together with a communication bus. Each data compression processing unit includes a wavelet transform processing unit, a shared register file and an address computation processing unit. The wavelet transform processing unit decomposes data from one or more segments of an image into wavelets using a discrete wavelet transform. The shared register stores the intermediate wavelet coefficient computations. The address computation processing unit identifies addresses of wavelets to be decomposed by subsequent operation of the wavelet transform processing unit. The system also includes storage where the resultant wavelet coefficients from each segment may be stored. The present invention also includes methods of compressing image data using multiple processors where each processor operates on a segment of the image data.

摘要： The present invention is directed to an electronic vision system. The system implements at least 3 apertures. A first aperture is set at near focus, while second and third apertures (positioned to the left and right of the first aperture respectively) are set at far focus. The fields of view of the left and right apertures may be spaced apart relative to each other, thereby forming a blind spot in the overall field of view of the system. However, the field of vision of the center aperture overlaps the blind spot, thereby reducing the blind spot for the system. The system includes a computer configured for receiving electronic image data from the apertures and rendering display data derived from the received image data. The system includes a display mounted to a mounting structure (ex.—helmet) for receiving the display data and displaying visual images of the display data.

摘要： A high dynamic range sensor assembly includes a plurality of sensing sets that are organized into a sensing array. Each of the sensing sets includes a set of sensing elements for sensing physical phenomena. Each set of sensing elements has a locally selectable integration time. An analog-to-digital (A/D) converter operatively connected to the set of sensing elements acquires and converts an analog signal from each of the sensing elements into a digital signal. A processor operatively connected to the A/D converter and to the set of sensing elements manages the selectable integration time for the set of sensing elements and analyzes the digital signals from each of the sensing elements in the set of sensing elements. The digital signals from each of the sensing elements are measured by the processor and an integration scaling factor for the set of sensing elements is computed and controlled by the processor to adjust the integration time. The integration scaling factor for the set of sensing elements is mathematically combined with a value of the digital signal from the A/D converter to form a larger data word than what is generated by the A/D converter. The larger data word is utilized to represent a magnitude of each of the sensing elements. If a substantial number of A/D values have saturated, the integration time is decreased; and, if a substantial number of A/D values are below a predetermined threshold, the integration time is increased.

摘要： A method and apparatus for capturing and processing images from a portion of a system in order to detect a warning condition for providing warnings to users or operators of the system. One or more image capture devices capable of capturing an image, for example, a continuous video, monitor at least a portion of the system. An image processing assembly processes the image captured by the image capture devices in real time for determining if the warning condition exists. Upon determining that the warning condition exists the image processing assembly causes a warning device to provide a warning to the user. The captured image may then be displayed to the user or operator if desired.

摘要： In an internal combustion engine having two or more coplanar cylinders radially disposed about a crankshaft, a crankshaft journal bearing arrangement in which the big ends of the connecting rods are each formed as segments of a continuous circular bearing for assembly about a single crankshaft journal. The big end of each connecting rod comprises an internal arcuate bearing segment and concentric external bearing segments. When assembled about the crankshaft journal, the external bearing segments are encircled by two containment rings whereby the internal arcuate bearing segments are maintained in operational engagement with the crankshaft journal. The containment rings are fixed for rotation with the crankshaft and relative sliding movement between the containment rings and the assembled connecting rod big ends occurs at the external bearing segments.
