Abstract: A flow meter system is disclosed that includes a first flow sensor and first and second fluid flow conduits extending from the first flow sensor. The second fluid flow conduit may be disposed inside the first fluid flow conduit thereby forming a fluid annulus between the first and second fluid flow conduits. The first fluid flow conduit may be metal to resist a fluid pressure differential and the second fluid flow conduit may be non-metal to balance a fluid pressure across the second fluid flow conduit and attenuate noise therein. The fluid annulus may be configured to receive a fluid to balance the fluid pressure across the second fluid flow conduit.

Abstract: One or more techniques and/or systems are disclosed for a vent-free heater that may be installed in an area used for human occupancy, to provide heat to that area. Such a heater can comprise an environmental detector that senses ambient air conditions, and may provide data used to shut down the heater in predetermined threshold condition. In one implementation, a vent-free heater for installation in high altitudes can comprise a combustion region and a fuel supply component. The heater can comprise an environmental detector with a flameless sensor configured to detect an ambient level of a constituent of the atmosphere and generate a signal indicative of the constituent level; and a sensor interface that can control flow of fuel from the fuel supply, based at least upon a signal received from the sensor.

Abstract: A cover for obstructing the camera of an optical head mounted display is provided. The cover comprises a sleeve having a cavity adapted to slide over an optical head mounted display camera. The sleeve removably attaches to the optical head mounted display camera via snap connectors located within the cavity of the sleeve. The sleeve is sufficiently flexible to accept insertion of the optical head mounted display camera and securely retain the optical head mounted display camera therein. The cover further includes an indicator on an exterior surface thereof designating that the optical head mounted display camera is not operational.

Abstract: Examples disclosed herein relate to systems and methods, which may utilize bingo mapping gaming options. The systems and methods may include bingo mapping functionality in a Class II environment.

Abstract: A frame for displaying lithophanes that utilizes either natural daylight or electric light as the source of illumination. Current display options for lithophanes rely solely on one light source or the other, thus limiting display options. This frame will allow users to display their lithophanes whenever and wherever they like. The frame is designed with a lip to hold the lithophane to be displayed and a recess to contain the electric light source. The frame is built with an electrical connector to accept the appropriate electrical adapter. The frame utilizes a reflective rear panel to direct electric light through the lithophane for display away from a window or at night. The rear panel is removable to allow display in a window using natural daylight.

Abstract: Embodiments include curable compositions including an epoxy resin and a hardener component including a terpolymer having first constitutional unit, a second constitutional unit, and a third constitutional unit, where the epoxy group to the second constitutional unit has a molar ratio in a range of 1.0:1.0 to 2.7:1.0. Embodiments include prepregs that include a reinforcement component and the curable composition and an electrical laminate formed with the curable composition.

Abstract: A method for storing memory test information includes the steps of storing a portion of information related to locations and numbers of failed memory cells detected while testing memory, and updating the stored information as failed memory cells are detected to indicate a first type of memory spare is to be assigned to repair a failed memory cell, a second complementary type of memory spare is to be assigned to repair the failed memory cell, or the memory is not repairable. The first type of memory spare corresponds to one of a row and a column portion of memory and the second complementary type of memory spare corresponds to the other of the row and column portions of memory.

Abstract: The invention relates to a method, apparatus and system for the treatment of organic and inorganic waste in a waste fluid. The method involves a co-current plug flow of fluid in a reactor in which ozone mass transfer conforms to the effective life of the ozone used in the treatment. Hydroxide and hydrogen peroxide can be added to the waste fluid. The combined fluids to be treated travel the reactor through a series of surfaces in a packed reactor. The apparatus includes a diffuser for ozone which assists in the co-current plug flow of fluids. The diffuser can have a porosity of about 10 microns. The invention further envisions a compact system for efficient treatment of waste fluids.

Abstract: A novel nickel-carbon electrode, and methods for making the same, have been developed. The nickel-carbon electrode comprises an active mass (e.g., a nickel oxyhydroxide, hydroxide or oxide) deposited to a carbon foam using any one of chemical deposition, thermal deposition or electrochemical deposition. The nickel-carbon electrode is formed or “activated” through a series of charge-discharge cycles. The nickel-carbon electrode is comparable in volumetric capacities (mAh/cc) with commercial nickel electrodes but higher in gravimetric capacities (mAh/g). The nickel-carbon electrode may be used in rechargeable nickel-based batteries which have applications in cordless appliances, portable devices, standby power systems, the aerospace industry, and hybrid electric vehicles.
