Title: Method and apparatus for recognizing cursive writing from sequential input information
Inventor: GUBERMAN SHELJA A
IPC: G06V30/262
Filed: 1993-09-03
Abstract: A method and apparatus for cursive script recognition employs an intermediate cursive words description language constructed of elements in the form of metastrokes wherein each of the metastrokes is a member of a metric space, the metric space being expressible as a matrix of likelihood of matching between input metastrokes and predefined metastrokes forming a vocabulary. Typically, a minimum of twenty metastrokes is used to form the vocabulary or set of allowable stroke elemental shapes, although as many as seventy may be used, with a correlation factor or measurement of similarity being defined between strings of metastrokes. Techniques for interpreting the metastrokes as words include substituting, adding, and deleting metastrokes in an input sequence, measuring similarity and comparing with entries in a dictionary of words constructed of metastroke sequences and variants of metastroke sequences.      Weighting of similarity may include penalties for lack of similarity.

Title: Detachable ignitor tip for a burner assembly
Inventor: GOSS CHARLES T
IPC: F23Q3/00
Filed: 1994-01-31
Abstract: ABSTRACT OF THE DISCLOSURE         An ignitor housing wherein a piezoelectric device is supported is releasably attached to a backpiece of a torch tip assembly.  The housing surrounds air inlet openings to allow passage of a high tension wire from the piezoelectric device to a support site downstream of the gas flow direction where spark gap is established.  An actuator button for the piezoelectric device is closely adjacent to the support site for the torch to enable the operator to operate the button while supporting and controlling the torch with one hand.  The site of the actuator button is very favorable for resisting the reaction forces to the actuating force on the button.  The housing is constructed to enable replacement of internal components of the ignitor as well as replacement of the housing on the backpiece.  The housing can be made from any of variety of materials because the support site on the backpiece always remains cool during operation of the torch.  In all embodiments, the torch includes a replaceable tip for a gas supply and supports the ignitor housing.

Title: Extrudable polyvinyl alcohol compositions containing modified starches
Inventor: FAMILI AMIR
IPC: C08L3/00
Filed: 1994-02-09
Abstract: ABSTRACT      An extrudable polyvinyl alcohol composition useful for packaging and molding applications is prepared by melt blending polyvinyl alcohol and thermoplastic modified starch to provide a product which has reduced water sensitivity, improved modulus and reduced elongation at high relative humidity.       A method for extruding the polyvinyl alcohol composition comprises:        adding sufficient energy to the polyvinyl alcohol composition to both melt it and essentially eliminate the polyvinyl alcohol crystallinity in the melt, and simultaneously removing energy from the melt at a rate sufficient to avoid decomposition of the polyvinyl alcohol.       The thermoplastic modified starch may be added to the polyvinyl alcohol before or during the melting of the polyvinyl alcohol and elimination of its crystallinity, or the starch may be blended with the thus treated polyvinyl alcohol and then melt extruding the polyvinyl alcohol/starch blend.

Title: Automatic electrophoresis method and apparatus
Inventor: SARRINE ROBERT J
IPC: G01N27/447
Filed: 1994-05-19
Abstract: An electrophoresis apparatus (30) for automatically per-forming medical assays includes an electrophoresis platform (48) which cooperates with a gantry assembly (56).   The electrophoresis platform and the gantry assembly are mov-able along paths that are perpendicular to each other.  An applicator assembly  (50)  includes pipettes  (52)  which transfer fluid samples from a specimen tray (158) to an electrophoresis plate (110) mounted on the electrophoresis platform.   The electrophoresis platform then moves to a position into the gantry assembly, where electrophoresis is conducted to separate the samples into different fractions. The electrophoresis platform then moves beneath a reagent pouring station (54) where a reagent is applied to make the separated fractions fluoresce under ultraviolet light.  The electrophoresis platform is then moved beneath the gantry assembly again, and an air knife (338) in the gantry assem-bly spreads the reagent.  After incubation and drying of the electrophoresis plate, the electrophoresis platform and gantry assembly are moved relative to one another while the electrophoresis plate is read with the aid of ultraviolet lamps (296) and a photomultiplier tube (312) mounted in the gantry assembly.  The gain of the photomultiplier tube is automatically adjusted and the data gathered is automati-cally edited to remove background noise.   The edited results can be printed or displayed on a video monitor.

Abstract: COLOR PHASE CONTROL FOR PROJECTION DISPLAY USING SPATIAL LIGHT MODULATOR           ABSTRACT OF THE DISCLOSURE      A SLM-based projection display system (10) samples and processes video data for delivery to a spatial light modulator (SLM) (13o), and uses a color wheel (14a) to color the SLM-generated images. A frame memory (13b) provides data to the SLM (13c) and is managed so that, if the phase of the incoming video signal changes, a desired phase relationship between the color wheel position and the data available to the SLM (13c) can be maintained. Also a motor control unit (15a) uses a horizontal sync signal to generate a drive signal for the color wheel motor (16a), which limits the transient time during phase-changing events, and which provides a means for adjusting the phase of the drivesignal.

Title: Fluid diverter
Inventor: GONZALEZ TEODORO J
IPC: F16K11/02
Filed: 1994-08-05
Abstract: A miniature diverter valve cartridge adapted to be received in a well in the side of a solid casing incorporated into a faucet assembly which includes a handspray unit. The diverter valve cartridge is positioned adjacent to the outlet port of the faucet assembly. The cartridge includes a housing and a piston shaft mounted in the housing for reciprocal movement, with a piston and a cup valve mounted on opposite ends of the shaft. The cup valve controls water flow to the spout of the faucet assembly. When the handspray is turned off, water pressure builds up within the interior of the cartridge in a manner such that the cup valve is moved off its seat to establish water flow to the spout. However, when the handspray unit is operated, water from the interior of the diverter valve flows into a passage leading to the handspray unit, and also into a further compartment on the opposite side of the piston. A differential pressure is created, so that the pressure in the inner compartment of the cartridge forces the piston to a position which causes the cup valve to seat securely against the housing and block the flow of water to the spout, with water flow passing through an output passage through the casing to the handspray unit. The pressure differential is achieved by providing a notch in an annular rim portion of the housing separating the inner compartment from the further compartment, the notch having a selected size to create sufficient pressure differential across the piston when the handspray unit is operated to farce the valve in a direction firmly to close the cup valve on its seat. The size of the notch is made sufficiently large so that particle contaminants may flow easily through the cartridge and into the handspray passage so as to avoid clogging of the cartridge valve.
