Title: Method of non-exhaustive motion estimation which times out
Inventor: KEITH MICHAEL
IPC: H04N7/50
Filed: 1994-05-12
Abstract: ABSTRACT     A method is provided for performing motion estimation in a system having a test image and a plurality of candidate images.  A candidate image is selected and the difference between the test image and the selected candidate image is determined.  The motion of an image is estimated according to this differencing and a determination is made of the duration of the motion estimation process in the system of the present invention.  The candidate image selection, the differencing and the motion estimation are then repeated according to the duration determination.   The duration determination may be a determination of a time duration or a determination of a number of machine cycles.  The system is adapted to iteratively decrease a measurement of the error between the test image and selected candidate images as these actions are repeated.  When the error stops decreasing and begins increasing the assumption is made in the system of the present invention that a best match has been determined.  Thus a best match is iteratively determined unless a time out occurs first.

Title: Split-ring breakaway connector
Inventor: THUERIG PETER
IPC: F16L37/088
Filed: 1994-05-13
Abstract: A tension-activated disconnecting coupling operates by having a plug portion penetrate and pick-up an expandable locking ring. On partial with withdrawal of the plug, the locking ring is carried into a confining region where expansion of the ring is constrained and the plug is effectively locked within the coupling. Applied tension thereafter overcomes an internal spring resistance and allows the locking ring to move out further, into a space where it may expand and release the plug.

Title: Flexible container with nonstick interior
Inventor: QUICK JAMES R
IPC: B65D30/02
Filed: 1993-05-14
Abstract: A flexible container for the packaging of products having a pressure sensitive adhesive (92) thereon, such as sanitary napkins. The container is formed of paper or plastic film (16) coated on one side with a layer of silicone, the container construction being such that the silicone coating defines the interior surfaces of the container. Due to the nonstick characteristic of the silicone coating, the usual protective layer for the adhesive on the packaged product can be omitted.      The side seams of the container are formed by the application of heat or ultrasonic energy in combination with mechanical deformation of the paper or film to produce embossments (18) in the seam areas. The side seams may comprise two or three layers of material. The nature of the side seams may be such that the container may be opened by peeling apart the seams, or the seams may be sealed so tightly that the container can be opened only by tearing the material.

Inventor: WAWRZYNIAK TIMOTHY J
IPC: B25B27/00
Filed: 1994-11-22
Abstract: An oil filter cover has a housing with a cylindrical sidewalk an open end, and an opposing closed end. A cavity in the housing extends through the open end and is adapted to receive an oil filter canister. An annular flange circumscribes the open end of the housing and extends inward from the sidewall to partially close around and seal against the oil filter canister. A piercing member extends into the cavity from the closed end to puncture the canister. The piercing member is mounted to a plate which is located in the cavity and abuts the closed end. Further, a series of longitudinal ridges extend into the cavity from the housing sidewall and are spaced circumferentially about the cavity. Each ridge extends at least partially between the open end and the closed end of the housing with some of the ridges extending to abut and hold the piercer mounting plate against the closed end. A protective sleeve is slip-fit over the housing to minimize damage to the cylindrical sidewall from a protruding structure adjacent the oil filter.

Title: Digital video signal processor apparatus with preprocessor for generating non-interlace-scan video signals from interlace-scan video signals
Inventor: WINE CHARLES M
IPC: H04N11/02
Filed: 1993-03-15
Abstract: A preprocessor for conditioning interlace-scan video signals for frame based compression, includes apparatus (40) to accept fields of interlace-scanned video and provide fields of interlace-scanned luminance and chrominance component signals.      The fields of interlace-scanned luminance component are combined (45) into respective frames of luminance signal and applied to compressor apparatus for further processing. The fields of interlace scanned chrominance components are independently processed (41,42) at the field level to generate lines of chrominance values which are interstitial to the lines of the original chrominance values and at a lesser pixel and line density. The independently processed fields of interlace-scanned chrominance signals are combined (43,44) into respective frames of chrominance component signals and applied to compressor circuitry (46) for further processing. Performing the chrominance signal interpolation and subsampling (41,42) at the field level tends to eliminate a majority of color distortions around moving images. Receiver apparatus (50) is configured to perform post decompression processing to generate frame data having the original pixel and line density.

Filed: 1993-10-19
Abstract: In a two-way interactive commu-nication video network having a ne-twork switching center (2) for point-to-point communications between sub-scribers at different geographic loca-tions, a local base station (3) configura-tion is provided for facilitating low power battery operated portable sub-scriber units (17). The local subscriber units surrounding a base station are adapted for multiplex transmission of digital messages synchronously related to a broadcast television signal for sys-tem coordination. Digital messages are transmitted from the local subscriber units to the base station data process-ing facility through a set of receive on-ly cell site subdivision zones distribut-ed over the base station transmitter geographical range, which communi-cate with the base station data processing facility over a communication link such as wired cable. Messages are compiled and rel-ayed by satellite to a network switching center transmitter site for nationwide point-to-point communications. Small-size, inex-pensive, low-power, portable, digital-transmitting subscriber units are introduced compatible with interactive video data system standards with the ability to cross subdivision and cell zones. Thus, monitoring of inventory, temperature, and other parameters for passive automatic alarm systems and the like, as well as active mobility of subscriber units for meter reading and the like is made possible with direct low-cost nationwide real time reporting capability.
