Title: Method for controlling a system, using signature verification
Inventor: NELSON WINSTON L
IPC: G06T7/00
Filed: 1992-05-15
Abstract: METHOD AND APPARATUS FOR CONTROLLING A SYSTEM, USING SIGNATURE VERIFICATION Abstract Forged signatures are discriminated from authentic signatures in a verification process which relies on dynamic signature properties. In an initialization phase 010, a reference set of authentic signatures is obtained. A set of dynamical properties 140.1, 140.2, 140.3 of the reference signatures is computed numerically. The most characteristic subset of such properties is selected and statistically analyzed to obtain a set of parameters for signature verification. An entrant signature is subsequently accepted or rejected 160, 170 based on its conformity to the parameters. An accepted signature is optionally passed along to a higher-level verification process. When a signature is accepted by the highest-level verification process, responsive means 050 are activated, resulting in the entrant's access to a system.

Filed: 1992-08-20
Abstract: DRILL BIT CUTTER AND METHOD FOR REDUCING    PRESSURE LOADING OF CUTTINGS                      ABSTRACT OF THE DISCLOSURE A drag-type drill bit for boring an earth formation having a plurality of cutting elements formed thereon. Each cutting element includes a cutting surfacehaving a cutting edge formed thereon. During boring, the cutting edge is embedded into an earth formation so that the formation is received against a portion of the cutting surface. As the cutting surface advances against the formation, a chip forms. The chip has a first surface directed generally toward the cutting surface and a second surface directed generally in the direction of cutting element travel . A number of different embodiments are disclosed which include means formed on and in the cutting surface for communicating drilling fluid pressure via slots or discontinuities to a location on the cutting surface relatively close to the cutting edge. Drilling fluid pressure across the chip is thus equalized thereby preventing the chip from being urged against the cutting surface due to the difference between the formation pressure and the drilling fluid pressure.

Title: Method and apparatus for heating subsurface soil for decontamination
Inventor: NELSON JOSEPH M
IPC: E21B43/30

Abstract: METHOD AND APPARATUS FOR HEATING SUBSURFACE           SOIL FOR DECONTAMINATION     ABSTRACT OF THE DISCLOSURE     A technique for in situ decontamination of an earth formation.  High gas temperatures can be achieved at subsurface formations by supplying a fuel at a subsurface location, such as at the bottom of a wellbore. Pressurized air or gas preheated to a temperature of about 700°F-1200°F is supplied to the wellbore to ignite the fuel.  The combustion heat produced by the fuel further heats the preheated gas to temperatures in the range of 1200°F-4500°, which heated gases are forced out of the borehole into the contaminated formation.  Contaminants are thereby volatilized or oxidized and removed from the formation to the surface.
