Abstract:

A measurement system processes data representing an images of an optical target, e. g. on a contact probe, to determine position of each of a number of points on a vehicle or other object. The system uses two reference frames and processes an image of the two frames, to define a three-dimensional (3D) coordinate system, for example, in relation to a designated first frame. The image processing determines the position of the other frame in that coordinate system. For any measurement in which the first reference frame is visible in an image with the probe, processing directly determines position of the point in the 3D coordinate system. For any measurement in which that reference frame is not sufficiently visible, but the second reference frame is sufficiently visible, the image processing determines position relative to the second reference frame and transforms that position into a measurement in the defined three-dimensional coordinate system.

Abstract:

A wireless vehicle service system using addressable devices to avoid interference from similar devices within communications distance. The system includes a host and a plurality of devices that communicate with the host wirelessly. Each of the devices has a unique address, and stores information describing the device, such as the type of the device, a system to which the device is associated, a location of the device, etc. During an enumeration process, each device sends signals including its address and the information describing that device to a host of the vehicle service system. The host stores relationships between the addresses and associated information. For signals sent by the devices and received by the host, the host decodes an embedded address from the signals, and obtains information related to the device sending the signals based on the decoded address and the stored information associated to the decoded address. The host then processes the received signals by referring to the information describing the device sending the signals.
