    Abstract: Complex computer graphics forms and motions can be constructed either by hand or with motion or geometry capture technologies, once they are created, they are difficult to modify, particularly at runtime. Interpolation provides a way to leverage artist-generated source material. Methodologies for efficient runtime interpolation between multiple forms or multiple motion segments enables computers to perform more realistic animation in real-time. Shape interpolation is applied to predefined figures to create smoothly skinned figures that deform in natural ways. Predefined figures are selected using a search technique that reduces the amount of interpolation required to produce real-time animation.

    Abstract: A GPS receiver (1) has an antenna (3) mounted directly on a first side (4) of a multilayer printed circuit board (PCB) substrate 2. Electrical conductors interconnect the antenna (3) with an RF processing system (11,12) and a digital processing system (10, 14, 15, 16) mounted directly on a second side (5) of the PCB substrate (2). A position connector (17) is disposed on one side of the PCB substrate (2) and provides power, ground, and direct electrical access of processed GPS signals for an external system such as a mobile vehicle system.

    Abstract: A traction assembly of a work machine having (i) a differential housing having an axle passageway extending therethrough and (ii) an axle positioned within the axle passageway is disclosed. The traction assembly includes a gear mechanically coupled to the axle. The gear includes (i) an outer peripheral surface having a plurality of sensor teeth defined therein, (ii) a first shoulder extending in a first lateral direction, and (iii) a second shoulder extending in a second direction. The traction assembly also includes a bearing assembly attached to the differential housing, wherein (i) the bearing assembly includes a first bearing member and a second bearing member, (ii) the gear is interposed between the first bearing member and the second bearing member, (iii) the first shoulder of the gear contacts a first journal surface of the first bearing member, and (iv) the second shoulder of the gear contacts a second journal surface of the second bearing member. The traction assembly further includes a sensor for detecting rotation of the gear relative to the differential housing and generating a sensor signal in response thereto.

    Abstract: A tire traction assembly for mounting upon a tire. The assembly includes a plurality of flexible members such as chains or cables engaged in pivoting connections with brackets at opposing ends. A separable adjustable connector such as a toothed member is attached to a first of the two brackets and configured for engagement with a ratchet mechanism attached to the second of the brackets to releasably secure the tire traction assembly around the tire. A plurality of traction cables configured to traverse the rolling surface of the tire are located in-between the brackets. The brackets may include a planar tread plate which has opposing planar side surfaces configuring the brackets to a U-shape.
