Granted: 1999-03-16
Abstract: Light is projected upon a road surface (LD) from a light source (11) for illuminating the road surface.          Diffuse reflected light from the road surface (LD) is received by light sensors (31A, 31B) through a spatial filter, and the resulting light-reception signals are applied to a differential amplifier circuit (51).  A center-frequency component corresponding to the spatial frequency of the spatial filter is extracted by a tracking band-pass filter (52), and the intensity (Da) thereof is detected by an amplitude detector circuit (54).  Low-frequency component intensity (Db) corresponding to a spatial frequency lower than the spatial frequency of the spatial filter is detected by a tracking low-pass filter (55) and an amplitude detector circuit (56).  The condition of the road surface is judged to be snow, gravel or asphalt in a discriminating circuit (60) based upon the center-frequency component intensity (Da) and the low-frequency component intensity (Db).

Abstract: Modified amino acids and methods for their preparation and use as oral delivery systems for pharmaceutical agents are described. The modified amino acids are preparable by reacting single amino acids or mixtures of two or more kinds of amino acids with an amino modifying agent such as benzene sulfonyl chloride, benzoyl chloride, and hippuryl chloride. The modified amino acids may form encapsulating microspheres in the presence of the active agent under sphere-forming conditions. Alternatively, the modified amino acids may be used as a carrier by simply mixing the amino acids with the active agent. The preferred acylated amino acid carrier is salicyloyl-phenylalanine. The modified amino acids are particularly useful in delivering biologically active agents, e.g., desferrioxamine, insulin or cromolyn sodium, or other agents which are sensitive to the denaturing conditions of the gastrointestinal tract.

Abstract: A crab pot having improved yield.  A traditional commercial crab pot comprises  a trigger structure that rotates between open and closed portions.   The crabs enter the trap by pushing trigger members inwardly as the crabs pass through a trap opening.  The trigger members are prevented from swinging outwardly, so crabs  should not be able to leave  through the trap opening.  To bias the  trigger structure into the  closed position,  the trigger  structure comprises a counterweight  member that biases the trigger members into a position where they span the trap opening and prevent egress of crabs.   A protection structure is provided which prevents crabs from interfering with the operation of the  trigger structure.   The protection structure prevents the crabs from interfering either with the portions of the trigger members which extend below the trap opening and/or the counterweight member located above the trap opening.

Granted: 2004-06-22
Abstract: A digital video cassette recorder (350) operates by the selection of predetermined replay speeds and the allocation of specific locations within each track from which data may be reproduced. These specific track locations are utilized during recording to place advance television image data for reproduction during "Trick Play" operation. The "Trick Play" image data (353) is also reproduced during normal playback but may not be utilized. The specific track locations are selected to facilitate "Trick Play" operation at a plurality of speeds in both forward and reverse directions. Since the advanced television signal comprises a plurality of predicted frames, transition from "Trick Play" to normal speed replay requires a control function which is responsive to the reproduction, at normal replay speed, of an interframe coded frame. Various methods of reproduced image transition are used for selecting both to and from "Trick Play" reproduction.

Title: Method and apparatus for decoding two-dimensional symbols in the spatial domain
Inventor: ZHENG JOE
IPC: G06K7/00
Filed: 1995-06-01
Granted: 2000-09-05
Abstract: A method and system for decoding a two-dimensional optical symbol in the spatial domain. The system determines the orientation of an imaged symbol in thespatial domain by using a template to derive a correlation coefficient between radially adjacent signals at a given angle of the template and comparing the correlation coefficients as the template is rotated with respect to the image. The angle of the highest correlation coefficient corresponds to the orientation of a set of symbol axes which include contiguous elements whose centers are collinear. The system then locates each individual information-encoded element of the symbol by using segments of the symbol defined by the axes, first adjusting for each segment the axis position and element size for subsequent determination of the location of all elements for decoding. The system is disclosed as applied to a symbol constructed as a matrix of hexagonal information-encoding elements arranged in a square, with, at its center, an acquisition target consisting of six concentric rings of alternating light and dark reflectivity. Also disclosed is amethod for locating an acquisition target consisting of a plurality of concentric rings of alternating levels of reflectivity (bull's-eye pattern) in two-dimensional symbologies. Such targets may be found even if they vary in size and tilt angle with respect to an imaging camera. Symmetry characteristics of the targets are used to locate the targets independent of the threshold level selected for determining transitions between rings of different reflectivity.
