Abstract: The technology described herein relates to a system for generating a simulated environment for, among other aspects, modeling property. In more detail, the technology relates to generating a virtual three dimensional (“virtual 3-D”) space having one or more virtual characters associated with one or more users. The virtual 3-D environment, in one non-limiting example, can simulate a process for selecting and viewing property by allowing a user to simulate engagement with a realtor and/or view and engage with the property using virtual reality technology. For example, a user may wear a virtual reality headset that enables him/her to simulate visiting a realtor's office where the user can then select one or more properties to view. Upon selection, the user may enter view the property in the virtual environment and engage with different elements associated with the property.

Abstract: A diverter assembly includes a tubing segment and one or more sleeve members disposed therein. The tubing segment includes apertures that are selectively alignable with apertures of an inner sleeve disposed within the tubing segment. The tubing segment includes a series of stops (e.g., shear pins) to arrest movement of the first sleeve within the bore of the tubing segment. A first one or more ball seats are included in the first sleeve such that deployment of a first ball and pressurization of the well above the first ball causes a first set of shear pins to fail, thereby allowing the first sleeve to slide downhole to cause apertures of the sleeve to align with apertures of the tubing segment, thereby causing fluid to flow to an annulus between the tubing segment and wellbore wall.

Abstract: An example of a metal-based pellet extrusion additive manufacturing system is disclosed. The system may include a printing nozzle system with a turnable screw, an extruder body, and a nozzle end, wherein the turnable screw is configured to transport metal-based pellets from an extruder body towards a nozzle end. A method for fabricating an object using metal-based pellet extrusion system is also disclosed. In one example, the additive manufacturing system and method are utilized to form a fan wheel for a fan assembly. In some implementations, the fan wheel is a monolithic part without any welds or other attachment features joining fan blades of the fan wheel to the base of the fan wheel.

Abstract: Described above is a system for allocating variable compensation to a group of individuals. The system displays objective financial statistics associated with individuals, and subjective factors to be set by a user, where the system can convert subjective factors set by the user into a value. The user can then select base and variable compensation values for each individual. Other details are described herein.

Abstract: An antenna system and method for managing identification, location, direction and communication with nearby wireless communication devices is provided. Various embodiments can be implemented to enhance the performance of advertising systems, location services, military systems, and social gaming.

Abstract: An electric motor-driven compressor includes a housing assembly comprising a motor housing and a compressor housing mounted thereto. The compressor housing contains a centrifugal compressor wheel that is mounted on a shaft of the motor rotor and also defines an air inlet that leads air into the compressor wheel, and a volute that collects the compressed air. Air bearings rotatably support the shaft. Cooling air passages are defined in the housing assembly for supplying cooling air to the air bearings. A diffuser between the exit of the compressor wheel and the volute serves to diffuse the compressed air. The compressor includes a heat shield formed separately from the compressor housing and the motor housing and disposed between them. The heat shield defines one wall of the diffuser and also cooperates with the housing assembly to define part of the cooling air passages for the cooling air supplied to the bearings.

Abstract: A mechanism for differential pressure sealing for use in a compressor, such as for fuel cell applications, is described. In a dual-stage compressor, a low pressure side and/or a high pressure side of the dual-stage compressor may include a compressor wheel supported by a shaft that can rotate about an axis of the shaft. A seal carrier may be provided that rotates with the compressor wheel and includes a groove for receiving a sealing ring, which may be a split expansion ring. A static seal plate may be positioned around a periphery of a portion of the seal carrier, such that the sealing ring can seal against a contact surface of the static seal plate when received in the groove in order to create a pressure differential seal. The low pressure side may include one sealing ring, whereas the high pressure side may include two sealing rings positioned in series.

Abstract: An electric motor-driven compressor having an electrical terminal block assembly and corresponding method of assembly are provided. The electrical terminal block assembly includes a base plate that has a staging feature for receiving a lug end of a motor stator cable prior to connection of the motor stator cable with a terminal bar of the terminal block assembly. In this way, once the terminal block assembly is lowered into the enclosure and the motor stator cable is no longer visible to the user, a stator cable fastener may be passed through a stator cable mounting hole in the terminal bar to engage the stator cable lug that is being held in the proper position by the staging feature of the base plate. Upon rotation of the stator cable fastener, the stator cable lug may be drawn into conductive engagement with the terminal bar.

Abstract: Apparatus and methods to lower peak temperatures and improve performance of aircraft anti-icing systems are described herein. One described example apparatus includes a skin on an inlet side of a nacelle of an aircraft defining an annular chamber, a gas delivery system disposed within the annular chamber to provide a first gas to mix with and entrain a second gas in the annular chamber to define a flow through the annular chamber, and a deflector vane disposed within the annular chamber to redirect the flow through the annular chamber. The second gas is at a different temperature from the first gas.

Abstract: An air bearing assembly is provided that includes a bearing sleeve that has two slots side-by-side having rectangular profiles for engaging the ends of first and second bearing foils for supporting a shaft of a dual-stage compressor. The first rectangular-profile slot, which may be made using a broaching process, is designed to receive first ends of the first bearing foil and the second bearing foil. The second rectangular-profile slot, which may also be made using a broaching process, is designed to receive a second end of the second bearing foil. This dual-slot design replaces the complex “L” shaped single slot design of conventional bearing sleeves, allowing for high-volume, low-cost manufacturing of the bearing sleeves. The dual-slot design also provides for robust engagement of the bearing foils with the bearing sleeves, while allowing easy assembly and installation of the air bearing assemblies.

Abstract: An electric motor-driven compressor includes a motor having a rotor and a stator in a motor housing, a low-pressure compressor mounted to one end of the motor housing, and a high-pressure compressor mounted to the other end of the motor housing, the compressors forming a two-stage compressor. The motor housing defines a convoluted liquid coolant passage having a plurality of axially spaced-apart, convoluted passageways arranged for serial flow of liquid coolant from the passage inlet, then through each of the convoluted passageways one after another, and finally out from the outlet. The coolant passage further defines at least a first bypass passage that intersects with the convoluted passageways and extends in a non-convoluted fashion so as to interconnect the convoluted passageways and provide an alternative flow path for the coolant.
