Patent number: 6389361Abstract: An invention for the filtering, sorting and analysis of microseismicity induced during production of fluid resources from their reservoirs which allows direct 4 dimensional measurements of all or many of the components of the permeability field as well as other petrophysical rock properties important to reservoir analysis and monitoring. The seismicity associated with the permeability field is identified by its spatial and temporal location in two general conoidal volumes, symmetrically disposed about the injection point in any well being used for this purpose (FIG. 1). The cone axes are parallel to the maximum compressive stress directions of the ambient stress field. Increasing fluid pressure causes seismicity to rapidly migrate outward from the injection points (FIG. 2). The seismicity moves at rates that are order of magnitudes greater than that of D'arcyian flow and covering distances measured in kilometers.Type: GrantFiled: October 15, 1999Date of Patent: May 14, 2002Assignee: STRM, LLCInventor: Peter Anderson Geiser

Patent number: 6296637Abstract: An electrosurgical electrode having a distal end for transferring the energy to the tissue and a thermal reservoir spaced apart from the distal end. The materials and shape of the electrode promote the flow of heat away from the distal tip so as to reduce the temperature of the tip during electrosurgery, to reduce tissue damage and to prevent the tissue from sticking to the electrode tip. The electrode is composed of a bio-compatible and highly thermally conductive metal, such as silver or gold of high purity, or alloy of those two metals. The shape provides a cross-sectional area that is constant or increasing as the distance from the tip increases. The rounded distal end transitions into a cylindrical section which then transitions into the thermal reservoir. The thermal reservoir is also cylindrical, having a cross-sectional area that is larger than the cross-sectional area of the first cylindrical section.Type: GrantFiled: May 28, 1998Date of Patent: October 2, 2001Assignee: Link Technology, Inc.Inventors: Jonathan O.

Patent number: 6263006Abstract: An electroluminescent solid state device includes an active body member that is formed of a single crystalline metal oxide, such as aluminum oxide, that is doped with a rare earth element, such as erbium and/or terbium and an activator atom such as oxygen and/or fluorine. The metal oxide body member is electron excited by kinetic electrons that are emitted by a cold cathode. The ends of the metal oxide body member are polished to form a Fabry-Perot resonator, thus providing for coherent radiation from the device. As an alternative to the use of a Fabry-Perot cavity, an acoustic wave generator is associated with the metal oxide body member in order to launch acoustic waves into the body member. The frequency of energization of the acoustic wave generator operates to select a radiation wavelength from one or more emission wavelengths that are produced by doping the metal oxide body member with one or more rare earth elements.Type: GrantFiled: November 22, 1999Date of Patent: July 17, 2001Assignee: Astralux, Inc.Inventor: Jacques Isaac Pankove

Patent number: 6208799Abstract: A TV cable system having one set-top per user. The set-top's VCR recording functions are automatically adjusted in a manner to accommodate the occurrence of a program-delay event or a program-cancel event by the TV cable system. The expected begin/stop time-slot during which a program is projected to occur is broadcast by the system's head end to each set-top, and this IPG data is stored in each set-top. Within each set-top, the currently stored IPG-data is periodically compared to IPG-data that was recorded in the set-top's VCR-record-timers at an earlier time. When the recorded IPG-data does not compare to the current IPG-data, the IPG-data that is recorded in the VCR-record-timer is automatically updated to the current IPG-data. When this automatic updating of one VCR-record-timer produces a time-slot conflict with a different VCR-record-timer, the conflict is resolved, either automatically or by a user-alert-message that enables user intervention to resolve the conflict.Type: GrantFiled: April 29, 1997Date of Patent: March 27, 2001Assignee: Time Warner Entertainment Company L.P.Inventors: Richard Marsh, Joe Edmonds, Haig Krakirian, Michael Leonard La Joie
