Abstract: The invention is a method and an apparatus for determining travel data of a travel device when wheels or rollers of the travel device intermittently have ground contact. The apparatus has an odometer on at least one measuring roller. For the correct determination of the travel data, there is a correcting device for correcting the path length measured by the odometer in the case of interruptions of the ground contact of the measuring roller. In the case of established, sporadic interruptions of ground contact, the measured path length is corrected for obtaining the actually covered path length.

Abstract: Method and apparatus for modifying an odometer reading in a vehicle navigation system to compensate for odometer errors. A first distance measurement is obtained from the odometer, and a second distance measurement is obtained from at least one other sensor. The difference between the first and second distance measurements is determined and an adjustment amount is generated in response thereto. A modification factor is then adjusted by the adjustment amount, the modification factor being for modifying the odometer reading. The odometer reading is then modified with the modification factor. A method and apparatus for selecting a pulse rate setting in a vehicle navigation system to correspond to a pulse rate associated with the odometer are also described. A first distance measurement is obtained from the odometer and a second distance measurement is obtained from at least one other sensor. The difference between the first and second distance measurements is then determined.

Abstract: A method for substantially reducing the error that accumulates in dead reckoning systems. The method includes determining heading changes from a dead reckoning system (10), testing for improbable heading changes (20), and setting to zero any invalid heading change (40). Testing for improbable heading changes (20) in differential odometry systems includes checking the sign of both prior (60) and next pulse count differences (70) and setting an invalid heading change flag (80) if either or both differ in sign. In systems using a heading rate sensor, testing for improbable heading changes (20) includes checking whether a heading change is below a minimum turn rate (90) and, if so, setting an invalid heading change flag (100).

Abstract: An in-line roller skate includes a transducer portion capable of sensing the rotary movement of at least one wheel on the roller skate and transmitting information concerning the same to a receiver worn on a user's wrist. In the preferred embodiment, the transducer portion includes a magnet attached to one of the plurality of wheels and a sensor positioned in a shoe portion to detect the magnet and produce electrical pulses containing information corresponding to the angular velocity of the wheel.

The transmitter transmits the coded signals to the receiver. The receiver demodulates the carrier wave, reproducing the digital data stream.

The encoder wheel, which is part of a travel-sensing mechanism, nests annularly with the drive mechanism so that the width of the combination is minimized. The travel-sensing mechanism can be assembled to the vehicle without disturbing the drive mechanism. There is enough radial clearance in the toroidal encoder wheel to permit the drive mechanism to move up and down within the encoder wheel. The encoder wheel has approximately the same outside diameter as the drive wheel, so certain common-mode measurement errors cancel. The encoder wheel and the drive wheel are approximately concentric and closely spaced laterally to minimize measurement errors that would otherwise occur upon turning of the vehicle.
