Abstract: A fuel system for a hydrogen-fueled internal combustion engine vehicle. A compressor/expander is installed in fluid connection between the fuel tank and the engine's fuel delivery system. The compressor/expander operates in compressor mode when the hydrogen fuel in the fuel tank is below a pressure desired for fuel delivery. It operates in expander mode when the hydrogen fuel in the fuel tank is above the desired pressure. The compressor/expander has inlet and outlet metering valves. A controller receives fuel tank pressure and temperature measurements and calculates timing of the metering valves to maintain the desired pressure into the fuel delivery system.

Abstract: A collaborative real estate search is described. Overlay data including indications of properties for sale within a geographic area are provided to a first user device. The overlay data are capable of being overlaid on a map of the geographic area on a user interface. Selections of some of the properties for sale are received from the first user device and a list of those properties is stored within a folder associated with the first user. The system enables a second user device—associated with a second user who is associated with the first user—to access the list of the properties selected by the user. This includes enabling the second user device to cause information regarding the properties to be stored within the folder. The information is made available for display on a user interface of the first user device.

Abstract: Embodiments of the present disclosure provide user interfaces for overlaying a displayed image of a geographic area with graphical information derived from a plurality of data layers that are received in response to a search query. The graphical information includes graphical indications derived from or included in the first one of the plurality of the data layers that show the locations of the subset of the plurality of land parcels in the geographic area. Other information is also overlaid on the image of the geographic area.

Abstract: A computer system for locating real estate service providers by navigating an aerial image map of a geographic region. The system determines a search region corresponding to the geographic region by use of geospatial information associated with the geographic region. Once the search region is determined, the system searches a database for real estate service providers that are associated with the search region and that satisfy certain predetermined criteria.

Abstract: An innovative web-based tool displays visual information about real estate. In one embodiment, an aerial image is overlaid with various data layers to visually present real estate data. Data associated with various embodiments of the tool can include tax parcel information, historical sales information, Multiple Listing Service information, school information, neighborhood information, and park information.

Abstract: An energy management system and method providing a holistic premise energy optimization and energy efficiency reclamation system comprised of an interconnected system of software, analytics and automated process that optimizes the energy generation and storage technologies, energy consumption, energy demand and energy utilization of energy consuming assets within a premise.

Abstract: Under an embodiment of the invention, a web site system maintains a real estate web page. The web page has an aerial image map of a geographic region that can be navigated by a user. The web site system facilitates online collaboration for real estate transactions. When the user registers, the system creates a user account for real estate information. Real estate agents and/or other real estate service providers selected by the user are granted shared access to the user's account by the web site system.

Abstract: Included are embodiments for asset management. At least one embodiment of a method includes receiving, at a performance assessment and optimization center, data from at least one asset, the asset being configured to service an environment and performing at least one calculation, from the received data, to determine whether the asset is operating properly. Some embodiments include in response to a determination that the at least one asset is not operating properly, providing an indication related to operation of the asset.

Abstract: An exhaust valve arrangement includes a cylinder having a top end, an exhaust conduit connected to the cylinder by an opening in the top end of the cylinder, the opening comprising a valve seat, a valve member comprising a valve stem and a valve head on the valve stem, the valve member being movable between a closed position in which the valve head is received in the valve seat and an open position in which the valve head is spaced from the valve seat, and a resilient member arranged to urge the valve member to a closed position. A piston is mounted relative to the valve stem, the piston being disposed in a second cylinder in flow communication with the exhaust conduit and arranged such that a change in pressure in the exhaust conduit changes a degree of compression of the resilient member.

Abstract: A leaning vehicle suspension. Preferred embodiments have two transversely-mounted steerable front wheels and a single rear wheel, but the vehicle suspension of the present invention may be used with two-wheeled vehicles or four-wheeled vehicles, and front and rear coupled vehicle suspensions may be employed. Two preferred embodiments of the vehicle suspension of the present invention are described. Both have a transverse leaf spring, left and right rotary dampers, and independent left and right parallelogram transverse control arms movably mounting left and right wheel mounting members to the vehicle's frame. A rocker member, to which the rotary dampers and leaf spring are mounted, is pivotally mounted to the vehicle frame by a central pivot bearing, permitting the rocker member to pivot about a longitudinal axis of the vehicle. The parallelogram geometry holds the front wheels at even camber throughout the suspension travel.
