Abstract: Apparatus and associated methods relate to generating redundant measurement of pseudo differential pressure using two absolute-pressure sensors, each exposed to a different environment. Each of the two absolute-pressure sensors has complementary first and second output nodes. The first output node has a positive relation with and/or response to increasing pressure, while the second output node has a negative relation with and/or response to increasing pressure. A first difference measurement signal is calculated based on a difference between the positive relation output signals of the first and second absolute-pressure sensors. A second difference measurement signal is calculated based on a difference between the negative relation output signals of the first and second absolute-pressure sensors. Both the first and second difference measurement signals are indicative of a pressure difference between the first and second environments.

Abstract: A transducer baseplate includes a base, a protrusion extending from the base along a longitudinal axis, a pair of opposed transducer receptacles defined within the protrusion, and respective pressure plena. The pressure plena are separated by a plenum wall, each plenum being in fluid connection with an area external to the protrusion through a respective pressure line. The pressure lines provide a direct fluid path to their respective receptacles.

Abstract: A pressure sensor comprising a housing, a diaphragm wafer, and an isolator configured to absorb lateral stress. The diaphragm wafer includes a fully exposed diaphragm, a fluid contact surface, a sensing element, and a support portion, where the support portion and the contact surface define a cavity. The isolator extends laterally from the support portion to the housing. The pressure sensor is easily drainable, eliminating the buildup of particulates, and the diaphragm can be directly wire-bonded to printed circuit boards, eliminating the need for extensive electrical feedthrough.

Abstract: A rack for supporting a bicycle in a generally upright position, the rack comprising a frame comprising a curb bar; and the curb bar comprising a mounting surface for exerting a counterbalancing force on a crank assembly of the bicycle to frictionally hold the bicycle in the generally upright position. When the bicycle is supported by the curb bar, the bicycle is positioned relative to the rack for securing the bicycle to the rack. The curb bar exerts a counterbalancing force on the pedal axle or the pedal of the bicycle. The counterbalancing force may be a frictional force or a torque. Bicycles can be supported on either side of the rack, the bicycles facing in either a forward or reverse direction. The bicycle may be secured to the rack at multiple points.

Abstract: A method and system are disclosed for safe, efficient, economically productive, environmentally responsible, extraction and utilization of dissolved gases in deep waters of a rare type of “exploding” lake, where methane (CH4) is accompanied by abundant CO2. CH4 is combusted to generate electricity. CO2 usually is considered a contaminant requiring removal to avoid power loss. Cleaning high CO2 levels from CH4, however, is costly and causes CH4 loss. Venting CO2 is environmentally undesirable. Or, if CO2 is disposed in water flow returned to the deep lake, danger persists. CO2 and CH4 are degassed efficiently together and input into oxy-fuel combustion. Three process outputs are: degassed nutrients-rich water flow, power and CO2+H2O exhaust, all usable for industrially productive purposes. Extracting and using both gases together in an integrated method advances safety, economic productivity and environmental stewardship. Previously, it has not been possible to accomplish these ends together.

Abstract: A computer-implemented system and method are provided for automatically determining rebate eligibility for purchased products. In one example, the purchased products may be travel-rebated products such as booked air travel itineraries. A database stores purchase information associated with purchased products purchased at corresponding purchase prices. A product administration system having a computer software-based product administration application interacts with the database and purchase information of a first purchased product is compared with purchase information of subsequently purchased products. The product administration application interacts with the database to determine if the first purchased a product matches a subsequently purchased product based on a set of matching criteria.
