Abstract: A method for the automated identification of a fingerprint consists in, first creating a pixel map of the fingerprint. The pixel map is then thinned to ease the finding of the coordinates of the points forming the epidermal ridges of the fingerprint. These epidermal ridges are then tracked and characterized mathematically. The mathematical characterization produces a set of values that can be compared to other sets of values characterizing pre-identified fingerprints and stored in a database. The apparatus adapted to carry out the method includes an input device to create a pixel map of a fingertip, a controller to execute all the computations on the pixel map and a storage device to store the resulting values characterizing the epidermal ridges on the fingertip.

Title: A split power, differential aided cvt
Inventor: VAN SOLKEMA JEFF
IPC: F16H37/08
Filed: 1999-04-14
Abstract: In building a continuously variable transmission (CVT), it is beneficial to find some way to extend the continuous range of the transmission into the negative transmission ratios. It would also be of benefit if the load that is transmitted through the friction-based portion of the transmission were reduced. This invention, a variation of the regular belt driven continuously variable transmission, does both of these. It works by coupling a belt type CVT to a differential.

Title: Device for isometric/dynamic exercise/training/testing
Inventor: SAMUELSSON ROLF
IPC: A63B21/055
Filed: 1997-11-20
Abstract: An apparatus for isometric/dynamic exercising apparatus which includes a separate bottom plate (1), wherein a flexible harness has both ends fastened to separate points on a bottom plate (1) and extends over the shoulders (22) of a user. The harness includes means for adjusting its length, so that a user wearing the harness on his shoulders and having his feet in contact with the plate is unable to stand upright or lie completely flat, so that his legs and back muscles can be stretched while exerting a maximum stretching force. A  load measuring device (70) is included in the harness. The exercise is performed by the user stretching his legs and back simultaneously, therewith applying load to the leg tensors and back tensors of the user. The work carried out during the straightening cycle performed by the user can be evaluated and the power and the total work can be determined by selection of cycle frequency and by measuring the total work time. If the harness is non-stretchable, isometric training exercises can be carried out. If the apparatus is resilient or includes a spring device, dynamic training/loading can be carried out.

Filed: 1999-06-14
Abstract: Rapid reestablishment of permanent virtual circuits (PVCs 15 1-15 6) between frame relay switches 12 1-12 4 in a frame relay (10) is accomplished by periodically polling the switches by a configuration controller (18) via an out-of-band connection to obtain PVC information from the switches. Should a fault occur, the fault is isolated and mitigated. Thereafter, the configuration controller (18) downloads the stored PVC information to the switches in parallel via the out-of-band connection to enable the switches to re-establish the PVCs quickly, rather than wait to do so via an in-band connection.
