  • Patent number: 9001118
    Abstract: A method for constructing an avatar of a human subject includes acquiring a depth map of the subject, obtaining a virtual skeleton of the subject based on the depth map, and harvesting from the virtual skeleton a set of characteristic metrics. Such metrics correspond to distances between predetermined points of the virtual skeleton. In this example method, the characteristic metrics are provided as input to an algorithm trained using machine learning. The algorithm may be trained using a human model in a range of poses, and a range of human models in a single pose, to output a virtual body mesh as a function of the characteristic metrics. The method also includes constructing a virtual head mesh distinct from the virtual body mesh, with facial features resembling those of the subject, and connecting the virtual body mesh to the virtual head mesh.

  • Publication number: 20140269956
    Abstract: The disclosed embodiments provide a system that tracks and compensates for input signal noise at a receiver of a data communication channel. In particular embodiments, the receiver of the data communication link receives an input signal which comprises two signal levels. Next, for each of the two signal levels, the system generates an error signal by comparing the input signal value of the signal level with an expected signal value for the signal level. The system then updates a threshold signal value based on at least one of the two error signals associated with the two signal levels. Finally, the system compensates for input signal noise in the received input signal using the updated threshold signal value.

  • Publication number: 20140257287
    Abstract: Disclosed herein are external fixation devices including at least an elongate rod, a housing and an actuation member. The housing is coupled to the elongate rod and the actuation member is rotatably coupled to the housing such that a central longitudinal axis of the actuation member is angled and offset with respect to a central longitudinal axis of the elongate rod. Rotation of an actuation portion of the actuation member about the central longitudinal axis thereof in a first radial direction causes the housing to translate along the central longitudinal axis of the elongate rod in a first direction.

  • Publication number: 20140257288
    Abstract: Described herein are external fixation systems for correcting bone deformities in adjacent bones or fragments thereof. The systems herein include first and second elongate rods that translate with respect to one another via rotation of an actuation member at an end of one of the rods. At least one housing is coupled along a length of one of the rods. The at least one housing includes at least one pin clamping member for clamping an end of a fixation pin therein. When the at least one pin clamping member is in an unlocked state, the fixation pin can rotate in polyaxial directions. When in a locked state, the angle of fixation wire with respect to the rods is set. The locked and unlocked state of the at least one pin clamping member is determined by the positing of a fixation member with respect to the housing it is coupled to.

  • Publication number: 20140006314
    Abstract: Illustrative embodiments of the present invention are directed to methods and computer systems for reporting unusual or anomalous usage or spending of a commodity by consumers. A computer system retrieves a set of usage-information datasets corresponding to a set of consumers, each dataset including past usage of the commodity during at least one of a completed billing period and a current usage of the commodity during the current billing period. The computer system establishes a set of report-trigger conditions for the current billing period, each of the report-trigger conditions corresponding to a consumer. The computer system monitor usage or spending of the set of consumers to determine, for each consumer, whether an estimated usage established for each consumer fulfills the consumer's report-trigger condition. Once the report-trigger condition is fulfilled, the computer system outputs a report to the consumer.

  • Patent number: 8500532
    Abstract: A method performed by a gaming apparatus is provided for handling hand tiles of a virtual player during a tile game. The tile game is played using plural virtual playing tiles from which the hand tiles are drawn. The gaming apparatus stores a preference parameter set associated with the virtual player and including tile points of the respective virtual playing tiles and combination points of various permissible combinations of the virtual playing tiles. During a turn of the virtual player, the gaming apparatus computes priority points of the respective hand tiles according to the preference parameter set, and then, makes the virtual player discard one of the hand tiles that is selected according to the priority points.
