Abstract: Described herein are systems, devices, methods, and media for an emergency response data exchange system. The system provides an operations center emergency management application with a textual and/or graphical notification of emergency communications initiated on a premises managed by the operations center. The system exchanges operations center data (e.g., floorplans, video feeds, point of contact information, building access controls) with an emergency communications center (ECC) and/or with a first responder device to facilitate reducing emergency response times. The system selectively establishes communications (e.g., messaging windows) between the operations center, ECC, and/or first responder device to facilitate real-time information sharing between relevant parties of an emergency.

The detector comprises a sorbent for sorbing therein and/or thereon and/or desorbing therefrom, an analyte included in a gas exposed thereto, at a zeroth temperature, pressure (T0, P0), a controller arranged to change the zeroth temperature, pressure (T0, P0) to a first temperature, pressure (T1, P1) according to a first equation, to desorb and/or sorb at least some of the analyte; and a sensor arranged to sense at least some of the analyte and to output a response corresponding to the sensed analyte. The response comprises and/or is a characteristic response of the analyte.

Abstract: Methods, apparatuses, and systems for making prepregs are disclosed. A method may include depositing a resin material onto a surface of a fiber bed and forming a number of discrete resin regions thereon. A distance between the resin regions may be measured to provide desired exposed portions of the surface to facilitate permeation of air through the exposed portions of the surface in a direction perpendicular to a plane of the fiber bed during a curing process of the prepreg.

Abstract: The interactive and shared surface technique described herein employs hardware that can project on any surface, capture color video of that surface, and get depth information of and above the surface while preventing visual feedback (also known as video feedback, video echo, or visual echo). The technique provides N-way sharing of a surface using video compositing. It also provides for automatic calibration of hardware components, including calibration of any projector, RGB camera, depth camera and any microphones employed by the technique. The technique provides object manipulation with physical, visual, audio, and hover gestures and interaction between digital objects displayed on the surface and physical objects placed on or above the surface. It can capture and scan the surface in a manner that captures or scans exactly what the user sees, which includes both local and remote objects, drawings, annotations, hands, and so forth.

Abstract: An embodiment of an exhaust collection system for collecting exhaust from a marine vessel includes an exhaust cleaning assembly including a tank. In addition, the exhaust collection system includes a vent hood in fluid communication with the tank of the exhaust cleaning assembly. The vent hood includes a frame including one or more extendable frame members, and an outer covering that covers the frame to define an enclosure with an opening configured to receive an exhaust stack of the marine vessel therethrough, the one or more extendable frame members to extend and retract to adjust a size of the opening.

Abstract: A submerged combustion melting system includes a furnace including a tank with a floor, a roof, a perimeter wall, and an interior, and burners to melt glass feedstock into molten glass, a batch inlet, a molten glass outlet, and an exhaust outlet. An exhaust system is in fluid communication with the interior of the tank, and includes a flue in fluid communication with the exhaust outlet. A refractory-lined hood may be in fluid communication with the flue, which may be fluid-cooled including fluid-cooled perimeter panels and lower and upper baffles. The hood may include a protrusion that protrudes into a downstream horizontal exhaust path and has an excurvate upper surface to streamline flow of exhaust gas through the hood to prevent gas recirculation and formation of condensate piles in the hood.

Abstract: A method of improving texture fetching by a texturing/shading unit in a GPU pipeline by performing efficient convolution operations, includes receiving a shader and determining whether the shader is a kernel shader. In response to receiving a kernel shader, the kernel shader is modified to perform a collective fetch of all texels for a group of output pixels instead of performing independent fetches of texels for each output pixel in the group of output pixels.

The methods described may find and extract faces from within groups of subjects, verify that the extracted faces correspond to the desired subject, determine cropping or masking regions, or both, of rectangular, circular, elliptical or some other geometry to provide an easily recognized image of the desired subject, expand the output image by synthesizing pixels as may be needed for a desired cropping or masking region, select preferred images among a collection of images of the desired subject, and perform other useful functions. The resulting output images may be in either direct form, reference form or both forms.

Abstract: A tissue repair apparatus includes a housing, a rotatable shaft at least partially disposed within the housing, and first and second curved needles coupled to the shaft. The housing defines a gap between a first edge of the housing and a second edge of the housing, the gap adapted to receive tissue. The first and second needles curved needles being articulable within the housing from a delivery position, at which the first and second needles are spaced from the gap, to a deployed position, at which the first and second needles extend through the gap. Actuation of the shaft simultaneously articulates the first and second needles and the first needle enters the gap before the second needle enters the gap.
