Abstract: An integrated navigation solution is provided for a device within a moving platform. Motion sensor data from a sensor assembly of the device is obtained, optical samples from at least one optical sensor for the platform are obtained and map information for an environment encompassing the platform is obtained. Correspondingly, an integrated navigation solution is generated based at least in part on the obtained motion sensor data using a nonlinear state estimation technique, wherein the nonlinear state estimation technique uses a nonlinear measurement model for optical sensor data. Generating the integrated navigation solution includes using the sensor data with the nonlinear state estimation technique and integrating the optical sensor data directly by updating the nonlinear state estimation technique using the nonlinear measurement model and the map information. The integrated navigation solution is then provided.

Abstract: Vehicle body tilt, representing a difference between a vehicle body frame of reference and a wheel-base frame of reference, is determined by obtaining information from sensor assemblies for the vehicle body and for the wheel-base. Navigational solutions are generated for the sensor assemblies using motion sensor data from the assemblies and absolute navigational information. Correspondingly, vehicle body tilt is determined based at least in part on the vehicle body navigation solution and the wheel-base navigation solution.

Abstract: A crank measurement system includes four bend-sensing strain gauges located on one surface of a crank and oriented parallel to a neutral axis of the crank to sense bend strain induced in the crank. Two of the bend-sensing strain gauges are located above the neutral axis, and the other two bend-sensing strain gauges are located below the neutral axis. The system also includes two shear-sensing strain gauges located on the one surface and oriented to sense shear strain induced in the crank. The shear-sensing strain gauges are located on opposite sides of the neutral axis. The system may also include up to four axial-sensing strain gauges located on the one surface and oriented to sense axial strain induced in the crank. An electronics module receives strain data from the strain gauges, and determines from the strain data one or more of force, torque, and power applied to the crank.

Abstract: A “sticker” location device includes a PCB with a processor and memory, a communicator for communicating with other location devices and a server, one or more sensors for determining an environment of the location device, and a power module. Some embodiments include GPS receivers and may serve as digital radio network hubs or bridges for other location devices. A method for tracking the location of assets uses these location devices attached to assets to sense an environment of the assets by comparing sensed environment to previously sensed environment, and communicating the changes in the environment from the location device to a server when the changes exceed a configurable threshold. Some embodiments include determining location with GPS and/or relaying signals from other location devices, and smart power management using low power digital radio modes unless sufficient energy is available for high power modes.

Abstract: A method and apparatus are presented for providing a compact extended ephemeris package for GNSS processing. An extended ephemeris service provides orbit trajectories and clock corrections which are predicted into the future for navigation satellites. The extended ephemeris package format used allows the ephemeris information to be sent quickly and efficiently, even when using a low bandwidth communication network. Client GNSS receiver devices obtain the extended ephemeris package and extract the satellite ephemeris information for later use. This allows a client device to operate for many days or weeks without needing to decode or receive new satellite ephemeris information.
