Title: Pixel adaptive noise reduction filter for digital video
Inventor: WU SIU-WAI
IPC: H04N5/21
Filed: 1998-04-30
Granted: 2004-07-13
Abstract: A current pixel of a video image is adaptively filtered to provide stronger filtering when there is a high likelihood that noise is present. Weaker filtering is provided when the presence of a color and/or brightness edge is likely in the video image. Each pixel has luminance and chrominance amplitude values. In a filtering method, a current pixel is intermediate to first and second pixels in the video frame. Difference signals are determined based on the amplitude difference between the current pixel and first and second adjacent pixels. A plurality of available filters provide successively stronger filtering of the current pixel amplitude. One of the filters is selected for filtering the current pixel according to the difference signals. Secondary difference signals which indicate the amplitude difference between the current pixel and pixels which are adjacent to the first and second pixels are also considered in the selection process. The selection process may further be biased by a user-selectable control word. The scheme may also provide temporal filtering with successive video frames or images. Filtering with pixel interpolation may also be used.

Abstract: A mouth-to-mouth resuscitator device for providing a physical barrier between a rescuer and a victim. The device comprises a flexible face shield having an opening formed therein. A tubular housing is sealed to the shield around the periphery of the opening and includes a rescuer air input end accessed from one side of the shield, and a victim air output end disposed on the opposite side of the shield. A self-closing one way valve arrangement comprising a flexible valve disc is contained in the housing to permit exhaled air under pressure to flow from the input end to the output end, and to prevent fluid back flow from the output end to the input end. A plate is secured in the housing to support the disc and provide a hinge for dividing the disc into a pair of flaps. A valve seat having a concave shape is provided to support the valve disc. The valve disc has a convex shape when the valve is closed. One flap of the disc pivots or bends outward from the valve seat in one direction and the other flap of the disc pivots or bends outward from the valve seat in the opposite direction, in response to the forced air applied at the input end by the rescuer for opening the valve and transferring the forced air to the output end; and the flaps resiliently pivot inward in opposite directions toward the input end for positioning on the valve seat to close the valve when the forced air has dissipated. The valve disc is stressed when in the closed-condition due to the valve seat blocking the valve disc from moving to its normal flat configuration. The valve disc abuts the valve seat in response to fluid back flow from the victim output end, to maintain the valve closed; and thereby blocking any fluid back flow from being transferred and discharged at the rescuer air input end. A pair of spaced apart rods are formed on the valve disc for attaching the valve disc to the support plate.

Abstract: A traffic control system (and associated method) according to the present invention includes a feedback control mechanism in which the controlled variable is processor occupancy, the controlling variable is the amount of resources necessary to satisfy the operational requirements of the switching system, and the set point is the average expected load based on a Poisson arrival rate. Current processor occupancy is compared, on an instantaneous basis against the set point to detenmine if it exceeds the average expected load. If so, the controlling variable is adjusted to allocate additional resources to process the offered traffic load. The process continues until the traffic burst expires. Additional resources may be obtained by eliminating or deferring non-essential work, and by allocating additional call registers, effectively accepting work in larger increments or batches. By instantly and proactively responding to traffic bursts, this traffic control system aids the switching system in weathering brief periods of high traffic, without actually reaching an overload condition and invoking overload controls. As a result, switching system capacity is increased, and other performance characteristics are improved.
