Abstract: An improved method of handwriting recognition is provided that combines the efficiency of a point oriented system and the shape information of a segment oriented system in an HMM based handwriting recognition system. The partial segmentation hypotheses obtained using the point oriented features in a conventional Viterbi search are augmented with scores based on segmental shape measurements made on the hypothesized segments. In addition, a new method is taught to improve segmentation of a handwriting sample. This is accomplished by incorporating a feature to distinguish between continuous and not continuous strokes and influencing the indicated hypothesis score by adding a penalty to the contraindicated hypothesis score.

Abstract: A water tube boiler using jet flames is disclosed which is capable of achieving low CO-emission combustion without enlarging a size of a combustion chamber. The water tube boiler comprises a combustion chamber 1 in which jet flames are generated and rows 3a to 3e of water tubes inserted through the combustion chamber. The group of water tubes provides a portion thick with the water tubes and a portion empty of the water tubes in a cross-section perpendicular to the direction of the jet flames, and at least the space Sa as an empty portion continuously extends through said group of water tubes in the direction of the jet flames. In the space Sa as an "empty" portion provided between the rows 3b and 3d of water tubes, recirculating flows (shown by arrows) of a combustion gas are generated. The recirculating flows are entrained by the jet flames existing the portion "thick" with the water tubes. Consequently, rapid temperature decrease of the jet flames is prevented. This enables the jet flames to flow downstream while maintaining a CO oxidation promoting temperature of about 1,000 to 1,500°C, thereby promoting CO oxidation reaction. Accordingly, residual CO of an exhaust gas is greatly reduced.

Abstract: Proposed is a powder of silica-cerium oxide composite particles useful as an ultraviolet shielding agent in a resin composition or as a sunscreening agent in a cosmetic composition. The cerium oxide-based composite particles consist of cerium oxide and 5 to 60% by weight of amorphous silica calculated as SiO 2 . The composite particles are prepared by the addition of sodium silicate and an inorganic acid to an aqueous slurry containing precipitates of cerium hydroxide so as to precipitate amorphous silica on the particles of cerium hydroxide followed by drying and calcination of the particles separated from the reaction mixture. Various formulations of cosmetic compositions compounded with the silica-cerium oxide composite particles are disclosed.

Abstract: Audiovisual programs are transmitted over a low-bandwidth network in
a compressed form in which the number of video frames has been reduced by
selecting "significant" frames. The user sees a series of still images accompanying
an apparently full audio channel. The frames are downloaded to the user in an order
designed to assure, first, that the next few frames necessary for viewing are present,
but also so that the user can scroll throughout the program even as it is being
downloaded. This is accomplished by first downloading the full audio for the
program portion requested by the user's viewer software, and then downloading the
video frames based on requests from the viewer software, which has access to a table
indicating which video frames are associated with which audio portions. The
software uses the table to download frames needed immediately, as well as to
download advance frames based on their significance.

Abstract: Electromagnetic interference ("EMI") is reduced in a CRT video display system by spreading-out the EMI-producing spectra present in the video pixel data and/or clock signals. A clock dropping circuit coupled between the display generator main oscillator and the timing generator periodically phase-modulates the timing generator clock signal such that it comprises N phases, where N≥2. As a result, each horizontal line of video data and the horizontal synchronization signals is phase shifted. This dual-shifting effect eliminates display image distortion that would result if only the video signal were shifted. Video distortion is further minimized by deriving the horizontal and vertical synchronizing signals from a common constant clock. EMI energy associated with each clock harmonic is spread by a frequency amount Af proportional to the rate of phase change in the clock signal, the rate of phase change exceeding half the bandwidth f m  of a standard EMI measurement reference window. This disperses adjacent spectral energy sufficiently so the reference window measures but one, decreased, amplitude at a time.

The ferrule (21) is a common dimensional structure for securing an optical fiber (99) and has a shape enabling the connection to any one of various kinds of housing members (30). Thus, the basic plug (20) connects separate optical fibers together through the housing member (30), which may also be an adapter housing member.

Abstract: A wafer position error and detection and correction system determines the presence of a wafer (10) on a wafer transport robot blade (20). The system also determines a wafer position error by monitoring the position of the wafer with respect to the blade with one sensor which is located proximate to each entrance of a process chamber. When a wafer position error is detected, the system determines the extent of the misalignment and corrects such misalignment if correctable by the wafer transport robot or alerts an operator for operator intervention. The system incorporates a transparent cover (30) on the surface of the wafer handling chamber (16) and four optical detection sensors (60) disposed on the surface of the transparent cover, in which each sensor is placed proximate to the entrance of the process chamber. In addition, an I/O sensor (66a) is placed adjacent to the I/O slit valve (25) to detect and correct wafer position errors. The detection sensors direct light through the wafer handling chamber to reflectors (62) on the floor (42) of the transfer chamber (16) which reflect the light back to the detector sensors. A detector (60) within the detector sensor detects when the beam path from the position sensor to the reflector is uninterrupted. As a wafer (10) is retracted out of a process chamber or a wafer cassette, the position of the wafer with respect to the blade is measured, thus determining whether the wafer is properly placed on the wafer.

Title: Adaptive noise removal for video images
Inventor: CAMPANELLI MICHAEL R
IPC: G06T5/20
Filed: 1997-12-11
Abstract: A method of applying noise removal to an image so that the areas having the greatest
variance have the least correction. First, the variance between each image pixel and its
surrounding pixels is determined. Next, for the neighborhood around each pixel, a density of
variance is determined. Finally the density of variance for the neighborhood around each pixel is
used to correct the original pixel, the direction of correction being toward the mean value in the
surrounding pixels. The result is that relatively uniform areas of the image, within which noise is
most obvious, will get the most correction and areas that are textured will get the least.
