  • Patent number: 10004982
    Abstract: Various embodiments described herein are directed toward alterable tokens. The alterable token may include a base including an RFID pattern. The base may include an electrical contact electrically coupled to the RFID pattern. The alterable token may include a rotatable body mounted to the base. The body may include first and second RFID tags. The body may include a first electrical contact coupled to the first RFID tag and a second electrical contact coupled to the second RFID tag. The body may be rotatable to a first and a second position. The RFID pattern may be electrically coupled to the first RFID tag when the first electrical contact contacts the electrical contact of the base in the first position. The RFID pattern may be electrically coupled to the second RFID tag when the second electrical contact contacts the electrical contact of the base in the second position.

  • Patent number: 8660815
    Abstract: A method of filtering noise in a three-dimensional position measurement system comprising receiving distance data representative of the respective distances between at least four spatially dispersed known points and an unknown point, performing triangulation calculations to determine at least two solutions to the three dimensional position of the unknown point relative to the known points, calculating a symmetrical bounding surface such as a sphere or cube which just encloses the said solutions, comparing the maximum dimension of the bounding surface with a first predetermined error threshold, and if the maximum dimension is less than the first error threshold, determining the center position of the bounding surface and outputting the center position as a noise-filtered position for the unknown point.

  • Patent number: 8654708
    Abstract: A position sensing system enabling dynamic adjustment of the sensing by dynamically adjusting amplifier gain or comparator thresholds in response to received signals. The system compares the time a signal takes to travel from a transmitter in a mobile component to a plurality of receivers in a fixed component and, adjusts the amplifier gain or comparator thresholds if the difference in times measured by the receivers is large or at least one receiver does not detect a signal.

  • Patent number: 8639471
    Abstract: According to various embodiments, the invention provides a method for establishing communication between a computer program in a computing system and a controller held in a hand of a user, comprising: capturing image data in a capture area in front of a display, the capturing configured to identify a two-dimensional location of the controller in the capture area; and capturing one-way sound communication between a location proximate to the display and a location at the controller, the sound communication being used to compute a third-dimensional location of the controller in the capture area.

  • Publication number: 20110069007
    Abstract: A gyroscopic pointing apparatus for an electronic device, particularly a games console, that is provided with means to detect when the mobile component is pointing at the screen upon which it controls a cursor to provide a mechanism to correct for drift in gyroscope readings and an improved method of dynamically recalibrating the zero point of the gyroscopes. The pointing detection mechanism may be provided by the combination of an infra-red LED and an infra-red sensor in either permutation on the mobile component and fixed component respectively.
