    Abstract: A traction enhancement device and system for the rear wheel(s) of a wheelchair is provided. The traction enhancement system generally includes a tooth bar assembly that includes a plurality of spikes/teeth and an actuation assembly that includes a lever and swashplate. In use the lever can be moved into ground engaging position and the swashplate will contact and provide a force the tooth bar assembly causing the spikes to extend beyond the diameter of the wheelchair wheel and into engagement with the surface on which the chair is riding. The lever can be pulled out of ground engaging position and the swashplate will not cause the spikes to push outwardly beyond the diameter of the wheel.

    Abstract: An adjustable length orthopedic device and system. According to one embodiment, the adjustable length orthopedic device or system comprises an elongated shaft with a longitudinal axis, and an adjustable portion extending from a proximal end of the elongated shaft along the longitudinal axis. The adjustable length orthopedic device further comprises at least one hole in a distal end portion of the device, where the hole is adapted for insertion of a pin through the device and into the bone in order to anchor the device to the bone. According to another embodiment is a lag screw extending from a proximal end of the elongated shaft at an angle oblique to the longitudinal axis, the lag screw comprising a lag screw shaft segment, and an adjustable segment that extends from the proximal end of the shaft segment. According to another embodiment is an adjustable length locking screw.

    Abstract: Various examples of systems, methods, and programs embodied in computer-readable mediums are provided for fingerprint liveness detection. Fingerprint liveness may be determined by evaluating pixels of a fingerprint image to identify pores along a ridge segment of the fingerprint image. A circular derivative operator can be used to identify the pores. Liveness of the fingerprint can be determined based upon features of the identified pores.

    Abstract: Disclosed are methods and systems for performing uncertainty calculations. For example, a numeric value and an error range associated with the numeric value are converted by a processor into a trans-imaginary input dual which is a hybrid of numeric and geometric information having real and complex numbers. A dual calculation is performed using the trans-imaginary input dual to produce a trans-imaginary output dual, and the processor then converts the trans-imaginary output dual to a real number output numeric value that includes both a real number and real number error range or uncertainty associated with that real number.
