Abstract: A method including rendering a view of a virtual environment of a video game for display in a head mounted display of a user, wherein the virtual environment includes a plurality of objects. The method including tracking gaze of the user. The method including detecting that the gaze of the user is directed towards an object in the view for a period of time. The method including generating a heads up display (HUD) interface including information related to the object. The method including surfacing the HUD interface near the object in the view of the virtual environment.

Abstract: A method for user interaction when gaming. The method including rendering a normal view of a virtual environment of a video game for display in an HMD of a user. The method including detecting a pose of a user holding a first controller and a second controller indicating that a virtual weapon is being held. The method including detecting that the pose of the user is raised to a firing position. The method including detecting that the pose of the user is in alignment with a face of the user. The method including detecting that a first eye of the user is closed. The method including detecting an object in the virtual environment being targeted by the pose that is in alignment with the face of the user. The method including rendering a magnified view of the object being targeted in the virtual environment for display in the HMD.

Abstract: A modular rack assembly for storing goods includes a first rack having a base and a plurality of wall portions extending away from the base. Each of the plurality of wall portions is separated from an adjacent of the plurality of wall portions by a space. A lip extends around a perimeter of the base. A second rack is generally identical to the first rack such that, in a first position, the second rack is stackable on top of the first rack such that the first rack engages the base of the second rack in a plane, and the lip of the second rack extends within the plane. A method of transferring heat between atmosphere and chub logs on the rack assembly includes the steps of loading chub logs onto a first rack and then placing a second rack on top of the first rack.

Abstract: The invention relates to the use of variable speed control of the cooling fan on a variable speed oil-injected screw compressor. A screw compressor (11) comprises at least one stage of compression, each with a pair of rotors, variable speed compressor drive means (12), an oil reclaimer (13) from the compressed air and cooling apparatus (17) for cooling the oil extracted from the compressed air. The cooling apparatus comprises a heat exchange device and a fan (18) driven by a motor (19) which can be run at different speeds.

Abstract: The invention relates to improvements in compressors and in particular to arrangements for driving screw compressors by reluctance drive motors. A screw compressor assembly is provided for compressed gas comprising a screw compressor having a casing (16) and at least one pair of intermeshing helically formed screw rotors (11,12) each of which is mounted on a rotor shaft rotatably mounted within the casing by means of bearings (15). Said assembly further comprises a switched reluctance motor comprising a stator (18) attached to the casing and a rotor (19) mounted on one of the motor shafts such that one of the screw rotors is driven directly by the motor.

Abstract: A multi-stage screw compressor includes at least two stages of compression, each compressor stage including a pair of rotors driven to effect gas compression. Each compression stage is provided with independent variable speed drive means and a control unit for controlling the speeds of the independent drive means. The control unit includes processing means for processing signals generated by a plurality of devices monitoring operating parameters of the compressor, and adjusting the speed of the drive means to provide a required gas flow delivery rate and pressure, at least one of the monitoring devices monitoring the torque and at least one of the monitoring devices monitoring the speed of each drive means.
