摘要:
A system and method for laser source detection. An exemplary embodiment of the system includes a first array of lenses, a second array of opto devices (including light sources and light detectors), and at least one processor. By positioning the array of lenses to determine the lens position at which energy from an incoming laser is greatest on the light detectors, the approximate location of the laser source may be determined. Upon determining the source, responsive action may be taken. If the incoming laser is from a friendly party, a friendly-party notification may be provided. If the incoming laser is from an enemy, reciprocal targeting or false reflections may be employed.

A heat exchanger for cryosurgical instruments comprises a mantle containing individual layers of a heat exchange substance, such as a heat exchange material or a heat exchange filler, an outer jacket surrounding the mantle, a contact zone within the outer jacket for receiving cooling fluid, and a heat detector in thermal contact with the outer jacket but separated by the mantle from the cooling fluid contact zone. Each of the individual layers of heat exchange substance is positioned within the mantle a spaced distance from every other individual layer, so that these individual layers of heat exchange substance are mutually separated from one another.

The present disclosure includes motion blur modeling methods and systems for image formation. One motion blur modeling method for image formation includes obtaining image data utilized to form a particular image taken by a camera of a subject, obtaining velocity vector data for the subject at the time the image was taken, defining a convolution kernel for use formation of the particular image and based upon the velocity vector data, and applying the convolution kernel to the image data to produce a de-blurred set of image data utilized to form the particular image.

A hand held matrix code scanner includes an orthogonal transfer charge-coupled device (OTCCD), a controller coupled to the OTCCD, and a sensor coupled to the controller. The sensor senses movement of the scanner The controller is configured to move a first location of the OTCCD array to a second location as a function of data from the sensor to compensate for the device motion during image exposure.

Image stabilization devices, methods, and systems are described herein. One image stabilization device includes a sensor having an array of pixels, wherein the sensor is configured to track a moving object using a number of the pixels, wherein the number of the pixels track only a particular portion of the moving object, and form an image of the moving object using the number of the pixels and their neighboring pixels that were not used to track the moving object.
摘要:
An apparatus includes a video sensing device, a velocity vector estimator (VVE) coupled to the video sensing device, a controller coupled to the velocity vector estimator, and an orthogonal transfer charge-coupled device (OTCCD) coupled to the controller. The video sensing device transmits a plurality of image frames to the velocity vector estimator. The controller receives a location of an object in a current frame, stores locations of the object in one or more previous frames, predicts a motion trajectory and the predicted location of the object on it in a subsequent frame as a function of the locations of the object in the current frame and the one or more previous frames, and transmits the predicted location of the object to the OTCCD. The OTCCD shifts its image array of pixels as a function of the predicted location of the object.
