Abstract: Various techniques facilitate the development of an image library that can be used to train and/or validate an automated visual inspection (AVI) model, such an AVI neural network for image classification. In one aspect, an arithmetic transposition algorithm is used to generate synthetic images from original images by transposing features (e.g., defects) onto the original images, with pixel-level realism. In other aspects, digital inpainting techniques are used to generate realistic synthetic images from original images. Deep learning-based inpainting techniques may be used to add, remove, and/or modify defects or other depicted features. In still other aspects, quality control techniques are used to assess the suitability of image libraries for training and/or validation of AVI models, and/or to assess whether individual images are suitable for inclusion in such libraries.

Abstract: A gas flow sensor housing and assembly including a gas flow sensor for measuring gas flow is disclosed. The housing includes a gas flow sensor mounting portion having a recess configured for mounting the gas flow sensor therein. The sensor includes a gas flow sensing element mounted to a substrate which is within the recess so as to avoid turbulence in the vicinity of the sensing element resulting from impingement of gas flow on a blunt or rough edge of the substrate. The gas flow sensor mounting portion includes opposed first and second edge portions, at least one of which is smoothly contoured to reduce turbulence in the vicinity of the sensing element. A method for measuring gas flow is also disclosed that employs the disclosed housing and sensor assembly.

In addition, the portable electricity generation device includes an air moving device configured to direct atmospheric air toward a cathode end of the plurality of fuel cells, wherein the air moving device is positioned to convectively cool the plurality of fuel cells as it supplies atmospheric air to the cathode end.

Abstract: There are many inventions described and illustrated herein. In one aspect, the present invention is directed to a portable fuel cell power and management system (for example, hydrogen and/or methanol based systems), components and/or elements thereof, as well as techniques for controlling and/or operating such systems. The fuel cell power management system (and method of controlling and/or operating same) actively monitors, manages and/or controls one or more operating parameter(s) of the fuel cell system. For example, the system monitors, manages and/or controls the consumption and/or the rate of consumption of fuel by the system, and in response thereto, may provide and/or alert the user to amount of fuel remaining, consumed, the rate of consumption and/or the time (or estimation thereof remaining until all of the fuel is spent. In this way, the user may schedule or plan accordingly.

Abstract: A proton exchange membrane (“PEM”) fuel cell stack and components of the fuel cell stack are provided. The fuel cell employs a plurality unique manifold assembly devices that allows for even distribution of the fuel source, e.g., hydrogen, to the anode side of the PEM and is designed so that the entrance orifice for the fuel source is larger than the exit orifice for the fuel source and/or reaction products. A pressure sensitive seal or a flexible, contoured seal is positioned around perimeter borders of the anode face of the PEM and the bipolar separation plate (“BSP”) to form a seal between the BSP and PEM. A sleeve, which is open-D-shaped in cross-section is provided that allows for even distribution of pressure on assembly of multiple fuel cells to form a fuel cell stack of the invention.

Abstract: A 1000 watt arc discharge arc tube assembly comprises two series connected side-by-side arc discharge tubes whose combined break down voltage in sufficient for a standard 2-5 kv starting pulse to simultaneously start both arc tubes without additional structure. A standard ballast, starter and fixture can be used with the arc tube assembly whose overall length is less than 300 millimeters. The lamps are spaced sufficiently apart to preclude detrimental heat transfer effects on one another and sufficiently close to act as a single source of light in standard fixtures normally employing lamps having a single discharge tube.
