Abstract: A stereo camera pair may be used to determine deformation and/or strain on a member based on differences in calculated movement of the cameras that capture images. In some embodiments, a first camera may be mounted to a first end of a member and a second camera may be mounted to a second end of the member opposite the first end. As the member bends, twists, or deforms in other ways, the deformation may be detectable based on differences in images captured by the first and second camera. This data may be used to detect possible wear or damage to the member, as a control input to a vehicle to reduce possible wear or damage to the member, as a prompt to initiate maintenance or inspection of the member, and/or for other reasons.

Abstract: In a method of executing a program on an interpreted bytecode language, a plurality of interpreted bytecode modules (each having an associated name) is loaded. A pointer is directed from each method entry to a different interpreted bytecode module. A native code module library is loaded and includes a native code module (also having an associated name) that implements a function corresponding to an interpreted bytecode module. When the name of an interpreted bytecode module corresponds to the name of a native code module, the pointer directed to the interpreted bytecode module is redirected to the corresponding native code module. Each interpreted bytecode module and native code module pointed to by the each method entry in the method table is executed according to an application-controlled order of execution.

Abstract: A delivery tracking system for tracking parcels during an internal state of delivery within an organization after receipt of the parcel from a parcel delivery service. The system utilizes an intelligent, hand-held, portable data entry and data processing device to obtain signatures of recipients and scan codes printed on the parcel labels, and to respond to tracking inquiries prior to transferring collected information to a different computer. Data is entered on a touch-sensitive screen of personal digital assistant using the tip of a wand type bar code scanner.

Abstract: A portable, hand-held apparatus for capturing a gray scale image of a signature within a box having fiducial marks in the corners. Portions of the image outside the box are trimmed away and the box is oriented and scaled to a standard size and shape. Signature storage requirements are minimized and signature recognition is facilitated by thresholding the gray scale image and thinning the strokes of the signature to an image width of one pixel.
