Abstract: Systems and methods to control operations of a camera based on one or more sensors attached to one or more actors. Sensor data collected from the sensors is analyzed to identify a state of an actor. The state of the actor is used to determine an operation parameter of the camera, such as the zoom level of the camera and/or the direction of the camera, and control the operation of the camera. For example, an actor who is in a state about to perform an interesting action can be selected from a plurality of actors; and the direction and the zoom level of the camera can be adjusted to focus on the selected actor in capture one or more subsequent images.

Abstract: Systems and methods to calibrate a gyroscope based on a motion of a predetermined characteristic. Data representing gyro sensor signals during a period of time is stored. A portion of the time period is identified, during which portion the gyroscope is subjected to a motion of the predetermined characteristic. Using the stored data the gyro signals are integrated with respect to time to calculate orientation of the gyroscope as a function of time. Deviation of a characteristic the orientation of the gyroscope as the function of time during the portion of time period for the motion of the predetermined characteristic is determined to identify a component of bias in the gyro signals. The bias component is removed from the data to re-calculate the gyroscope orientation, and possible to further calculate the deviation in the re-calculated orientation and to identify a further bias component in the gyro signals.

Abstract: A method and apparatus for detecting a jump of a moving sportsman and separating the jump from other sportsman motion is described. Accelerometer data generated by a sportsman's motion is received in a computing device. The computing device is used to apply fuzzy logic membership functions to a plurality of parameters associated with the accelerometer data to detect a pattern associated with jumps. A subset of the data is identified as representing a jump based upon the detection of the pattern. The determination is used in the computing device to transform data, whereby jumps are separated from other sportsman motion.

Abstract: Embodiments of the present disclosure are directed to a method and apparatus for calibration of gyro sensors by using magnetic sensor measurements and background computation during normal product operation. In one embodiment, magnetic sensor measurements are used to adjust gyro gain by comparing measured magnetic vector orientation with its expected orientation computed from gyro integration. The background process constantly compares this discrepancy for various values of gyro gain and selects the one that minimizes such error on average. In one embodiment, device orientation obtained by gyro integration is improved by using magnetic sensor measurements.

Abstract: A method, machine-readable medium, and system involve receiving user input with a navigation device regarding a desired city name. A determination is made regarding whether the user input matches city names in a Last Used City List (LUCL). A Global City List (GCL) is consulted when the user input does not match the city names in the LUCL. A matching city name is selected as a best candidate.

Abstract: A navigation device includes a processor, a map information storage medium storing map information, a position determining module configured to determine a current location, a velocity and direction of travel of a vehicle, and determine whether the current position indicates a deviation from an original route to a final destination. Further included is a routing module configured to determine an original route from a starting position to a destination, and at least one reroute from the current location to the destination, wherein the reroute includes a restoration route from the current location to at least one intermediate point on the original route and then continuing to the destination. Based upon an estimated cost of the restoration route plus a predetermined actual cost of the route from the intermediate point to the final destination, the routing module is further configured to estimate a reroute cost, and select a reroute based upon the estimated reroute cost.

Abstract: A traffic data server wirelessly provides relevant traffic details to mobile subscribers at minimal data transmission, while supplying enough data for re-routing and detouring. Two-way wireless data connectivity allowing the server to know what data the mobile device has received in the past, allows the server to send, to a mobile device, only data that is necessary, i.e. updates to mobile users that are small data sets comprising the change in the previously received data to the current data.
