Title: Evaluation circuit for a digital rotational speed transducer
Inventor: CLAUSSEN ULF DR
IPC: H02P29/00
Filed: 1981-10-27
Granted: 1985-08-14
Abstract: An evaluation circuit for receiving the output signals from a tachometer, the output signal consisting of first and second speed-proportional pulse trains which are phase-shifted with respect to one another in response to the direction of rotation. The evaluation circuit converts the phase-shifted pulse trains into a speed-proportional pulse train having a frequency which is four times that of the first and second pulse trains, and into a separate sign signal indicative of the direction of rotation. The first and second pulse trains are conducted to respective first and second signal memories which are controlled by a clock signal. In one embodiment, four possible states for the combined first and second pulse trains are assigned respective designating numbers. The count in a bidirectional counter is caused to follow changes in the designating numbers, the bidirectional counter counting pulses from the clock signal until such coincidence is achieved. The pulses so counted represent the desired speed-proportional pulse train. The present evaluation circuit operates to produce correct speed-proportional and direction-indicating signals even where the pulses of the first and second pulse trains are in phase with one another.

Title: Vascular grafts with cross-weave patterns
Inventor: MATTERSON SAMUEL A
IPC: D03D19/00
Filed: 1984-05-17
Granted: 1987-12-03
Abstract: Graft prostheses are woven with cross-weave patterns to prevent unravelling and to increase suture hold strength. A vascular graft according to the invention is woven as a continuous tube by shuttling a continuous weft thread through a double-layer array of warp threads. As the weft thread is shuttled through the warp pattern, groups of warp threads are retained in parallel relationship to each other while interspersed pairs of warp threads are crossed over each other. This results in graft having normal weave patterns circumferentially alternating with cross-weave patterns.
