Richard A Faulk, J Howard Ho: Reciprocating converter. Compaq Computer Corporation, Robert Groover, Betty Formby, Matthew S Anderson, June 16, 1998: US05768118 (139 worldwide citation)

A power converter which transfers energy from an output circuit coupled to a secondary winding of a power transformer to an input circuit coupled to a primary winding of the power transformer in order to reduce the power loss and electromagnetic interference (EMI) originating from a primary switch. ...

David R Baldwin, Andrew Bigos: Graphics subsystem with coarse subpixel correction. 3Dlabs, Robert Groover, Betty Formby, Matthew Anderson, January 14, 1997: US05594854 (139 worldwide citation)

A graphics processing system in which sub-pixel correction is implemented in a new and more economical way. A half-pixel offset is originally imposed on both the X and Y axes, so the sub-pixel correction value may be positive or negative. A relatively coarse resolution is used for subpixel correctio ...

David Robert Baldwin: Rendering architecture with selectable processing of multi-pixel spans. 3DLabs, Robert Groover, Betty Formby, Matthew S Anderson, June 9, 1998: US05764243 (109 worldwide citation)

A rendering system with multi-pixel span processing capability. When 3D graphics processes are not required, 2D data is processed in multi-pixel span fragments. Span fragments permit parallel processing of multiple pixels in a serial architecture, and permit VRAM block fills for accelerated processi ...

Richard A Faulk: AC/DC portable power connecting architecture. Compaq Computer Corporation, Robert Groover, Betty Formby, May 25, 1999: US05907197 (109 worldwide citation)

A portable computer system which includes a modified C-7 power cord socket, which can receive either an AC power cord with a standard C-7 connector or a DC power cord with a modified C-7 connector. (However, the modified C-7 connector cannot be inserted into a standard C-7 socket.) Microswitches in ...

Mark A Reed: Sub-nanoscale electronic systems and devices. Yale University, Robert Groover, Betty Formby, December 31, 1996: US05589692 (105 worldwide citation)

A new class of electronic systems, wherein microelectronic semiconductor integrated circuit devices are integrated on a common substrate with molecular electronic devices.

David Robert Baldwin: Graphics pre-processing and rendering system. 3dLabs, Robert Groover, Betty Formby, Matthew S Anderson, June 9, 1998: US05764228 (94 worldwide citation)

A 3D graphics system in which a pre-rendering stage is combined with a rendering stage. Any GUI window which is not completely displayed on-screen (because it extends past screen boundaries or is overlapped by other windows, etc.), is divided into at least two portions, e.g. rectangles, for scissori ...

Richard A Faulk: Converting battery module with resistor programmation of default output voltage. Compaq Computer Corporation, Robert Groover, Betty Formby, October 13, 1998: US05821734 (92 worldwide citation)

A universal battery pack which includes an integral power converter and a dynamically adjustable output voltage. The default output voltage is set by an optional resistor connection, which shifts the voltage-dividing ratio into the error amplifier. In a multiple-battery configuration, the output vol ...

David Robert Baldwin: Graphics rendering system with reconfigurable pipeline sequence. 3DLabs, Robert Groover, Betty Formby, Matthew S Anderson, August 25, 1998: US05798770 (88 worldwide citation)

The preferred embodiment discloses a pipelined graphics processor in which the sequence can be dynamically reconfigured (e.g. between primitives) in a rendering sequence. The pipeline sequence can be configured for compliance with specifications such as OpenGL, but may also be optimized by reconfigu ...

John Walter Neave, Neil F Trevett, Jonathan David Salkild deceased, David Joseph Salkild heir, Iain Stuart MacNaughton: Computer system with improved pixel processing capabilities. 3Dlabs, Robert Groover, Betty Formby, Matthew S Anderson, June 30, 1998: US05774133 (85 worldwide citation)

A computer system having a pixel processing unit with multiple subprocessors receives positional data defining graphical objects from the CPU and writes pixel data into the image memory, and a display driver produces an image which partially includes the rendered pixels. The pixel processor is used ...
