Inventor: WHEELER JERRY D
IPC: H04N1/12
Filed: 1997-11-06
Abstract: An optical reading head system has a calibrated pixel output, consisting of a discrete value for each of a plurality of pixels. The system has a scanning station (10) with an exposure region that includes an image region and a detector (35) including an array of photosensitive sites (30a) that sense reflected light from the exposure region during a detector exposure period to generate a pixel output profile of the image region. There are a plurality of light sources (20a, 21a) for lighting the exposure region. Each light source emits an individually controllable amount of light to the exposure region during a detector exposure period such that the system's pixel output is acceptably calibrated.     A calibration medium is supplied with a calibration region, and a target pixel output profile is defined for the calibration. The individually controllable light sources are adjusted to make the pixel output file acceptably within range of the target pixel output profile.

Patent CA-2275537-A1 (CA)
Title: Ccd scanner having improved specular reflection discrimination
Inventor: HECHT KURT
IPC: G06K7/10
Filed: 1998-01-29
Abstract: An optical scanner utilizes two linear CCD detectors and a bandpass means to improve the ability of the scanner to discriminate against specular reflection. A coded symbology is illuminated by a noncoherent light source and light reflected from the coded symbology along a first path strikes the front face of the bandpass means. The bandpass means, functioning as a notch filter, transmits a select bandwidth of light while reflecting all other light onto a first CCD detector. Simultaneously, light reflected from the bar code symbol travels along a second path, at a different angle with respect to the plane of the coded symbology than the first path, is reflected from a mirror onto the back face of the bandpass means. The bandpass means transmits the select bandwidth of light onto a second CCD detector and reflects all other light.  The second CCD detector has a notch filter which permits the detection of only the select bandwidth. Since specular reflection is only experienced at a single angle, with respect to the plane of the coded symbology and each CCD  detector detects an image at a different angle with respect to the plane of the coded symbology, a complete image can be reconstructed by combining information obtained from both CCD detectors.

IPC: G10L15/065

Abstract: In the speech recognition system disclosed herein, each input utterance is converted to a sequence of raw vectors. For each raw vector, the system identifies that one of a preselected plurality of quantized vectors which best matches the raw vector. The raw vector information is, however, retained for subsequent utilization. Each model of a vocabulary word to be recognized is in turn represented by sequence of states, the states being selected from a preselected group of states. However, for each word module state, there is provided both a discrete probability distribution function (pdf) and a continuous pdf characterized by preselected adjustable parameters. A stored table is provided which contains distance metric values for each combination of a quantized input vector with model state as characterized by the discrete pdfs. Word models are aligned with an input utterance using the respective discrete pdfs and initial match scores are generated using the stored table. From well matching word models identified from the initial match scores, a ranked scoring of those models is generated using the respective continuous pdfs and the raw vector information. After each utterance, the preselected continuous pdfs parameters are adjusted to increase, by a small proportion, the difference in scoring between the top and next ranking models. Preferably, if a user corrects a prior recognition event by selecting a different word model from the respective selected group, a re-adjustment of the continuous pdfs parameters is accomplished by performing, on the current state of the parameters, an adjustment opposite to that performed with the original recognition event and performing on the then current state of the parameters an adjustment equal to that which would have been performed if the newly identified different word model had been the best scoring.

Abstract: An arrangement for anchoring a roof of a building so that it can resist wind forces captures each roof truss, or other roof framing member, under a wire rope passed through a sequence of eyebolts protruding above a top plate of one of the walls of. Each of the eyes is the upper portion of one of a plurality of rod assemblies, each of which is connected to a respective one of a plurality of anchors disposed beneath the wall. A turnbuckle connecting each rod assembly to a respective eyebolt is used to draw the eyebolt down against the top plate and hence apply tension to the wire rope. A connecting nut at the bottom of each rod assembly attaches the rod assembly to a threaded upper end of an anchor set in the foundation of the building. Thus, tightening the turnbuckles firmly ties down the roof to the foundation.

Abstract: Matrix metalloproteinases (MMPs) are a group of enzymes that have been implicated in the pathological destruction of connective tissue and basement membranes. These zinc containing endopeptidases consist of several subsets of enzymes including collagenases, stromelysins and gelatinases. TNF-.alpha.  converting enzyme (TACE), a pro-inflammatory cytokine, catalyzes the formation of TNF-.alpha. from membrane bound TNF-.alpha. precursor protein. It is expected that small molecule inhibitors of MMPs and TACE therefore have the potential for treating a variety of disease states. The present invention provides low molecular weight, non-peptide inhibitors of matrix metalloproteinases (MMPs) and TNF-.alpha. converting enzyme (TACE) for the treatment of arthritis, tumor metastasis, tissue ulceration, abnormal wound healing, periodontal disease, bone disease, diabetes (insulin resistance) and HIV infection having formula (I) wherein R2 and R3 form a heterocyclic ring and A is S, S(O), or S(O)2, and R1 and R4 are defined herein.
