Abstract:
A plurality of modules interact to form an adaptive network in which each module transmits and receives data signals indicative of proximity of objects. A central computer accumulates the data produced or received and relayed by each module for analyzing proximity responses to transmit through the adaptive network control signals to a selectively-addressed module to respond to computer analyses of the data accumulated from modules forming the adaptive network. Interactions of local processors in modules that sense an intrusion determine the location and path of movements of the intruding object and control cameras in the modules to retrieve video images of the intruding object. Multiple operational frequencies in adaptive networks permit expansions by additional networks that each operate at separate radio frequencies to avoid overlapping interaction. Additional modules may be introduced into operating networks without knowing the operating frequency at the time of introduction. Remote modules operating as leaf nodes of the adaptive network actively adapt to changed network conditions upon awaking from power-conserving sleep mode. New programs are distributed to all or selected modules under control of the base station.
Abstract:
An image processing system implements recursive 3D super precision for processing smoothly changing video image areas by performing temporal noise reduction and then 2D super precision. The temporal noise reduction is applied to two frames, one being the current input low precision frame, and the other being the previous higher precision frame from memory. The 2D super precision is applied to the noise reduced frame to output a high precision frame which is also saved into memory for processing the next incoming frame. The input frame has a limited bit depth while the output image has an increased bit depth.
Abstract:
The system described herein is a unified approach to three-dimensional filtering for the reduction of video noise. The technique is based on weight averaging pixels of the filter's output value in a three-dimensional neighborhood, in space and time, of the filter's output value. The weights can be computed for individual factors, such as distance, regional differences, etc., or can be combined into a weight that is indicative of all individual weights.
Abstract:
A system and method for adaptively defining a region of interest for motion analysis in digital video is disclosed. In one embodiment, a method of detecting a gesture is disclosed which comprises receiving a video sequence comprising a plurality of frames, determining a region of interest which excludes a portion of the frame, and detecting the gesture within the region of interest.

Abstract:
An entertainment system that includes an image capture device which captures images of new users and mathematically processes the images so that a matrix of representative images of all known users if formed. The matrix can then be applied to subsequent new images to determine whether a new image of a user is a known user to the system to that preferences associated with the user can be employed in the delivery of entertainment content to the user.

Abstract:
An example-based method and system for electronic display color calibration is provided. By comparing the colors of commonly available objects with a color database under a controlled lighting condition, the user adjusts the gain and offset parameters of the Red, Green and Blue color components of the display. Two different methods are provided, wherein one method involves manipulating the comparison colors in the RGB color space, and the other method involves manipulating the comparison colors in the CIE x-y plane. Two different systems that incorporate the example-based color calibration methods are also provided, wherein one system directly implements the calibration method in the television system, while the other system implements the calibration method as a separate tool for viewers to calibrate the color of their displays.
Abstract:
A method and corresponding systems for using remote control to realize standard colors on displays. Two examples of remote controls are provided, one with color sensors and the other with white LEDs. For each example a calibration pattern is displayed which allows a user to calibrate the display color conveniently. For using the remote control with color sensors, an algorithm for the display to adjust the input RGB color, based on the color measurements from the remote control is provided. This allows the display output RGB color so that the display shows the same color as the input RGB signal is sent to standard color display.
Abstract:
A transuctaneous fluid kit for controllably evacuating fluid from a fluid site to a fluid collector, while preventing an outrush of fluid from the fluid site. A cannula is provided for fluid collection at the site to be drained. A Y-connector is provided at the proximal end of the needle. A one-way valve is mounted to the first leg of the Y-counter to prevent the outrush of fluid upon insertion of the cannula to the fluid site. A second leg of the Y-connector is provided for carrying evacuated fluid to a collection device via tubing.
