Abstract: An apparatus and method for inspecting an object by optical triangulation, where the signal of interest in a captured image corresponds to an interaction between a light beam and an environment surrounding the object rather than between a light beam and the object itself. The surrounding environment may be configured to interact in a manner that is detectable by filling it with a flowable scattering medium, e.g. a gas, mist or vapour comprising a suspension of fine particles in air. Light that is scattered by the flowable scattering medium is visible in a captured image. Where the flowable scattering medium is not present, e.g. because the object blocks it, the scattered signal is less. A boundary of a scattered signal region may thus provide information about the location of an object.

Abstract: A system for facilitating a medical procedure includes an access device that is configured to provide distance information regarding anatomical structures as the access device is driven to a target anatomical site. For instance, the access device can have either or both of a camera and neuromonitoring electrodes. The camera can send real-time images of the anatomical structures as the access device is driven toward the target anatomical site. The electrodes can emit an electrical current to identify a distance from nerve structure. A visual display can include the anatomical structure identified to the operator to assist in guiding the access device to the target anatomical site.

Abstract: Systems, apparatus and methods to supplement, combine, replace, verify and calibrate in-vehicle and in-device sensors and GNSS systems are presented. A mobile device and a vehicle navigation system share sensor and GNSS information to arrive at an improved navigation solution. For example, a navigation solution computed by a vehicle may rely on a sensor signal from a mobile device. Similarly, a navigation solution computed by a mobile device may use a sensor signal or a GNSS signal from a vehicle.

Abstract: Methods and apparatuses for position determination and other operations. In one embodiment of the present invention, a mobile station uses wireless signals from a plurality of wireless networks (e.g., with different air interfaces and/or operated by different service providers) for position determination (e.g., for data communication, for obtaining time and/or frequency information, for range measurement, for sector or altitude estimation). In one embodiment of the present invention, mobile stations are used to harvest statistical data about wireless access points (e.g., the locations of mobile stations that have received signals from the wireless access points, such as from cellular base stations, wireless local area network access points, repeaters for positioning signals, or other wireless communication transmitters) and to derive location information (e.g., position and coverage area of the wireless access points) for the wireless networks from the collected statistical data.
