Abstract: Manual and camera-based avatar control is described for example, in computer game systems. In one embodiment, an image capture system tracks motion of a player's arm holding a real world object and the player also makes input to the game system at the same time, using a manual controller. In an example, tracked motion of a player's arm is used to control aim of a virtual dart in a game display and the player makes manual input at the controller to fire the dart. In various embodiments, position of a part of a player is detected and mapped to screen space using a mapping function which may vary. For example, a mapped position of a player's hand in screen space is used to control the position of an avatar's hand by extending the avatar's arm. In examples, conditions are met before camera-based control of an avatar.

Abstract: Control of separate computer game elements is described. In one example, a computer game system displays a computer game to a user, the computer game comprising at least one avatar and an environment. Manual input commands are received from a hand-operated controller operated by the user, and are used to control the display of the avatar in the computer game. Substantially concurrently with the manual input, a stream of images from an image capture device depicting the user is also received. A portal, separate to the avatar, is displayed in a region of the computer game display, which shows the received stream of images to the user. The stream of images of the user is analyzed and a gesture performed by the user is recognized. The recognized gesture is used to control displayed interaction between the portal and the environment.

Abstract: Manual and camera-based game control is described. In one embodiment, a game system receives an image stream depicting a player of a game and also receives manual input from a hand operated controller used by the player. In an example, the manual input may be used to control an avatar and the image stream is used to recognize gestures of the player and control background objects in the game using the recognized gestures. For example, by using gestures such as head rotations the player's hands are free to continue operating a hand-held controller and the player has increased control and an immersive game play experience. In various embodiments, methods for detecting head gestures from image streams in real time are described such as tracking velocity of player's heads and motion through quadrants of an image stream.

Abstract: The present invention provides a Distinct Author Identification System (“DAIS”) for disambiguating data to discern author entities and link or associate authorships with such author entities. The invention provides powerful disambiguation processes applied across one or more databases to yield a disambiguated authority database of authors. An entire database of publications may be processed by the DAIS to group/link authorships and to identify author entities. The author entities may then be matched or associated with actual authors to establish an authority database of authors. After initial evaluation, the DAIS may be used to reevaluate some or all of the database(s) and/or the authority database established by the DAIS may be used to add or update information. DAIS may use “hierarchical clustering” to link authorships and identify authors based on authorship similarity. DAIS evaluates the likelihood that authorships are from the same author.

Abstract: A wafer handling mechanism is operated to place a wafer on a chuck. A chucking force is then applied to the wafer, whereby wafer support features of the chuck transfer a defect pattern onto a surface of the wafer. The surface of the wafer is analyzed by a defect metrology tool to obtain a mapping of the defect pattern transferred onto the surface of the wafer. A center coordinate of the chuck within a coordinate system of the wafer is determined by analyzing the defect pattern as transferred to the surface of the wafer. A spatial offset between the center coordinate of the chuck and the center of the wafer is determined. The spatial offset is used to adjust the wafer handling mechanism so as to enable alignment of the center of the wafer to the center coordinate of the chuck.

Abstract: A delineator post adapted to spring back to its original upright position after an impact comprises an inground socket permanently installed in a paved surface. A resilient plug having a lower end portion is inserted in the inground socket. The resilient plug has an upper end portion projecting upwardly from the inground socket. An anchor is provided for releasably anchoring the resilient plug to the inground socket. A post segment is fastened over the upper end portion of the resilient plug. The tension in the resilient plug when subject to a deformation as a result of an impact on the post segment returns the post segment back to its original upright position.

Abstract: A force balanced instrument system and method for mitigating errors is provided. The system and method mitigate errors in measurement readings caused by charge buildup in force balanced instruments that employ charge pulses to generate an electrostatic force to null an inertial proof mass disposed between opposing electrodes. The system and method mitigate charge buildup by applying positive charge pulses alternately to each opposing electrode for a given charge cycle time period followed by negative charge pulses alternately to each opposing electrode for a second given charge cycle time period. The negative charge pulses remove any residual charge on the electrodes caused by the positive charge pulses. As a result the net residual charge left on the electrodes is reduced on the average.

Abstract: A slimline cassette assembly for rotating a louvre blade connected therewith is disclosed. The cassette assembly is capable of fitment within the stile of a frame supporting a plurality of such cassettes and an array of louvre blades connected therewith. The cassette assembly has a body for receiving a pair of straight cut mitre gears therein. The gears are located relative each other so that rotation of a first one of the gears by means of a perpendicular spline shaft connected in axial alignment therewith and extending between corresponding first mitre gears of consecutive cassette assemblies, causes rotation of the other second gear in each cassette assembly about ˜n axis perpendicular to the axis of each first gear. Rotation of the perpendicular shaft is thus imparted uniformly to the array of louvre blades connected in axial alignment with each of the respective second gears of the cassette assemblies.
