Title: Cell voltage monitor for a fuel cell stack
Inventor: BARTON RUSSELL HOWARD
IPC: H01M8/04
Filed: 2001-06-26
Abstract: Voltage reversal in fuel cell stacks may be detected and/or prevented by monitoring each cell or small groups of cells in the stack for low voltage conditions. An improved cell voltage monitor (2) is constructed using a plurality of voltage monitoring units in which each unit comprises a heating resistor (Hi), a rectifier (Ri) in series therewith, and a sensing thermistor (STi) in thermal communication with the heating resistor. The heating resistor is electrically-connected across a cell or cells and heats the associated sensing thermistor in accordance with the voltage of the cell(s). Since the resistance of the sensing thermistor is indicative of its temperature and hence also of voltage of the cell(s), the sensing thermistor resistance can be used to signal a low voltage condition.

Title: Image segmentation system and method
Inventor: FARMER MICHAEL EDWARD
IPC: G06Q40/04
Filed: 2002-12-16
Abstract: The present invention relates in general to systems used to process images, In particular, the present invention is an image segmentation system and method used to isolate the segmented image of a target person, animal, or object from an ambient image which includes the target person, animal, or object, in addition to the area surrounding the target. The invention supports the ability of an airbag deployment system to distinguish between different types of occupants by providing such deployment systems with a segmented image of the occupant. The invention is particularly useful at night or in other environments involving inadequate light or undesirable shadows. The invention can use histograms and cumulative distribution functions to perform image thresholding. Morphological erosion and dilation can be used to eliminate optical "noise" from the image. Gap filling is performed on the basis of the "momentum" and "gravity" of regions of similar pixel values. An upper ellipse can generated to represent the upper torso of the occupant. The invention is highly flexible, and can be modified in accordance with the desired use.

Abstract: L'invention se rapporte à un élément filtre dans lequel un film filtrant annulaire présentant d'excellentes caractéristiques est formé intégralement sur un substrat en verre. Cet élément filtre est fabriqué puis découpé le long d'une ligne passant par le centre de l'anneau du film filtrant aux fins de la production d'une pluralité d'éléments filtres dans lesquels les films filtrants dotés de caractéristiques excellentes sont formés de manière à présenter généralement une forme arquée. Ces éléments filtres ainsi divisés sont découpés à angle droit par rapport à la corde de l'arc aux fins de la production d'une pluralité de bandes d'élément filtre (140, 140,...). Ces bandes d'éléments filtres sont ensuite réarrangées de sorte que leurs films filtrants (120a, 120a,...) doté de caractéristiques excellentes puissent être disposés sous forme de réseau sensiblement linéaire. Les bandes d'éléments filtres réarrangées sont découpées perpendiculairement à la direction de découpe précédente, ce qui permet de produire les puces filtres cibles. Lorsque le film filtrant est un film à plusieurs couches optiques, les éléments filtrants sont en outre placés sur un étage avec les films tournés vers le haut, et ils sont découpés au moyen d'une scie de découpage en dés.

Title: Method of accessing data and logic on existing systems through dynamic construction of software components
Inventor: VERMEIRE DEAN R
IPC: G06F40/143
Filed: 2002-01-17
Abstract: A record layout in a legacy application is defined by the record definition (11) in the source code of the language in which the application was written.  For each record in a legacy application(21), the layout of the record is saved in a language-neutral and architecture neutral format (13) in preparation for a runtime invocation. During runtime, for each record, the legacy application can send architecture-specific binary information as it exists in memory on the legacy computer to a component runtime environment that will construct a compatible object-oriented instance of a class to manipulate the information.  Once the information is manipulated, the updated information can be represented to the original legacy application in an architecture-specific binary record layout.

Title: Stepper motor jam detection circuit
Inventor: FORSEY WAYNE MICHAEL
IPC: H02P8/36
Filed: 2003-07-22
Abstract: Methods, devices and circuits for detecting malfunctions in stepper motors. A signal from a driver circuit to a stepper motor that is proportional to the current in the windings of the stepper motor is detected. This signal is then amplified and integrated for ease of comparison. The resulting signal is then compared to a specific entry in a table of values with each entry in the table corresponding to an operating profile of the stepper motor. If the resulting signal does not correspond to the operating profile for which the motor a configured, the stepper motor is jammed. A suitable alarm and a corresponding sequence of actions may then be triggered.

Abstract: Selon un aspect de l'invention, il s'agit d'une structure d'empilement d'une pile à combustible qui comprend plusieurs séparateurs pour la pile à combustible et une partie saillante dotée d'une pointe qui entre en contact avec la partie correspondante d'un bâti de montage à l'assemblage de la pile. Puisque la pointe de la partie saillante entre en contact avec la partie correspondante du bâti de montage, aucun agent adhésif ne s'écoule de la pointe de la partie saillante. On évite ainsi toute perte de précision du positionnement dans l'empilement des piles, cette perte étant causée par l'adhérence de l'agent adhésif qui s'étend à la partie correspondante du bâti de montage. De plus, la structure permet d'empêcher les courts-circuits causés par la déformation du séparateur dans le cas où il entrerait en contact avec la partie correspondante du bâti de montage.

Title: Ex-vivo priming for generating cytotoxic t lymphocytes specific for non-tumor antigens to treat autoimmune and allergic disease
Inventor: SHI WEIXING
IPC: A61K35/12
Filed: 2002-05-13
Abstract: Cytotoxic T lymphocytes (CTLs specific for antigenic peptides derived from I gE molecule can be generated in vitro by stimulating resting naïve CD8 T celles with IgE peptides presented by artificial antigen presenting cells. The IgE specific CTLs lyse the target cells loaded with IgE peptides in vitro and inhibit antigen specific IgE response in vivo. In addition, adoptive transfe r of the IgE specific CTL to an asthmatic mouse model can inhibit the development of lung inflammation and airway hypersensitivity. IgE specific C TL provides a treatment for allergic asthma and other IgE-mediated allergic diseases. Antigenic peptides identified from non-tumor self-antigens induce specific cytotoxic T lymphocyte (CTL) in vitro. The CTL induced by peptides identified from CD40L can kill activated CD4 T cells. In vitro generated CTL specific for CD40L inhibit CD4-dependent antibody responses of all isotypes in vivo. In contrast, CTL induced by antigenic peptides derived from IgE specifically inhibit IgE responses, and adoptive transfer of CD40L-specific CTL to NOD mice at early age delay the adoptive transfer of CD40L-specific C TL to NOD mice at early age delay the development of diabetes in NOD mice. In vitro generated CTl specific for non-tumor sel-antigens expressed on activat ed CD4 T cells regulate immune responses in vivo.

Title: Tandem axle assembly with different hypoid offsets
Inventor: TURNER GARY A
IPC: B60K17/36
Filed: 2002-05-22
Abstract: A tandem axle assembly is provided. The tandem axle assembly includes a forward axle assembly (12) and a rear axle assembly (14) and an intermediate drive shaft assembly (16) extending between the two axle assemblies. The forward and rear axle assemblies both includes a pinion gear (98) rotating responsive to an inter-axle differential (22) and a ring gear (100) in mesh with the pinion gear. The forward pinion gear is offset from the rear ring gear by a first predetermined distance (H1) while the rear pinion gear is offset from the rear ring gear by a second predetermined distance (H2). The second predetermined distance is greater then zero, bit is less than the first predetermined distance. The variation in offsets enables both equal working angles (21,22) in the intermediate drive shaft assembly and a reduction in those angles as compared to convertional tandem axle assemblies. Further, the variation in offset results in stronger and quieter gearing.
