Abstract: A selectable detent assembly that has a housing with a plurality of passageways. Within the housing is a selector spool that is disposed within a selector passageway and is rotatable to provide a plurality of rotational positions including a no detent position, a kick down position, and a continuous detent position. A pilot check valve is disposed within the housing and provides a fluid flow path from a pilot passageway to the selector passageway and a detent passageway. A detent arming piston is disposed within the detent passageway and is connected to a directional control valve spool. Thus, depending on the rotational position of the selector spool, the selector spool can either provide a continuous flow path through the selector passageway to a tank, a flow path that is controlled by the axial position of the selector spool or prevent flow to the tank in order to operate the detent arming piston.

Abstract: Real-time image stabilization using computationally efficient corner detection and correspondence is provided. The real-time image stabilization performs a scene learning process on a first frame of an input video to obtain reference features and a detection threshold value. The presence of jitter is determined in a current frame of the input video by comparing features of the current frame against the reference features using the detection threshold value. If the current frame is found to be unstable, corner points are obtained from the current frame. The obtained corner points are matched against reference corner points of the reference features. If the number of matched corner points is not less than a match point threshold value, the current frame is modeled using random sample consensus. The current frame is corrected to compensate for the jitter based on the results of the modeling.

Abstract: A method for capturing surveillance images includes of a secured area has a first camera with a first field of view and a second camera with a second field of view. An optical center is determined for the second field of view. A magnification ratio is determined between a target located in the first field of view relative to the second field of view. A pan and tilt model is determined that provides a relationship between a first camera coordinates and pan and tilt values to position the second camera at the optical center. A target is captured in the first field of view and the second camera is controlled to record the target in the second field of view with the second field of view being an enhanced view relative to the first field of view.

Abstract: The invention consists of a system and method for transferring video images from video sources to video receivers using a video server as an intermediary. The video server creates a list of all the requests from the video receivers for a video image from a video source. The video server requests the video image from the video source and then sends the video image to each video receiver on the list. The video source is only required to send one image for any number of requests from video receivers and the video sources and video receivers have no direct connection to each other. The load of handling many video sources and many video receivers can be distributed amongst multiple video servers.

Abstract: A system and method for filtering video noise is provided. Video generated under low lighting conditions is susceptible to increased noise and graininess, which increases the required storage space required for recording the noisy video. The provided system and method for filtering video noise reduces noise in low-light video by estimating the noise profile associated with at least one video frame; discriminating between chrominance noise and luminance noise in said noise profile; applying predetermined filter criteria to said chrominance noise to estimate the parameters for luminance noise filtering; applying said luminance noise filtering parameters to filter the luminance noise; and generating a first filtered output of a frame by logical combination of outputs obtained from luminance noise filter and chrominance noise filter.

These materials are combined to provide a thin film having a ? of at least 0.02 ?-cm (typically 0.02-1.0 ?-cm), and a TCR of less than ±1000 ppm/° C. (typically less than ±300 ppm/° C.). A sheet resistance of at least 20 k?/? may also be obtained. The resulting thin film is preferably at least 200 thick, to reduce surface scattering conduction currents.

Abstract: The present invention provides a JFET which receives an additional implant during fabrication, which extends its drain region towards its source region, and/or its source region towards its drain region. The implant reduces the magnitude of the e-field that would otherwise arise at the drain/channel (and/or source/channel) junction for a given drain and/or source voltage, thereby reducing the severity of the gate current and breakdown problems associated with the e-field. The JFET's gate layer is preferably sized to have a width which provides respective gaps between the gate layer's lateral boundaries and the drain and/or source regions for each implant, with each implant implanted in a respective gap.
