Abstract: A system is for monitoring a sterile field associated with a medical procedure. The system may include a sensor being adjacent an area where the medical procedure is to be performed. The sensor is configured to monitor at least the area, a patient for the medical procedure, and a medical technician for the medical procedure. The system may include a processor coupled to the sensor and configured to detect a sterile field event, and an associated location for the sterile field event, and an output device coupled to the processor and configured to generate an alert indicator when the sterile field event is detected, the alert indicator also including the associated location.

Abstract: The invention comprises an improved system, method, and computer-readable instructions for recognizing pose and action of articulated objects with collection of planes in motion. The method starts with a video sequence and a database of reference sequences corresponding to different known actions. The method identifies the sequence from the reference sequences such that the subject in performs the closest action to that observed. The method compares actions by comparing pose transitions. The cross-homography invariant may be used for view-invariant recognition of human body pose transition and actions.

Abstract: Methods and systems for a differential compressed sensor to form a smart optical imager that uses both active (laser) and passive (ambient light) to sample the direct image information within a three-dimensional spatial frame. The lens-based distance sensor is produces smart sampling of target by adjusting the size of the laser beam spot on the target sampling grid to produce a boundary outline by a light flooding. This target dependent direct sampling of the target results in direct compressed sensing. A passive light acquisition pin-hole sampling optical sensor design is proposed that produces the pixel-basis Laplacian to determine the compressed sensed pixels in the incident image.

Abstract: In one embodiment, a system and method for designing an optical surface pertain to constructing a matrix of radial basis functions, each column of the matrix corresponding to a radial basis function, selecting an initial surface to be used as a starting point, selecting initial weights for the radial basis functions, generating an initialized optical surface based upon the selected initial surface and initial weights, and optimizing the initialized optical surface to minimize an error function.
