Patent number: 6459435Abstract: A storyboard of interior design surface treatments for a commercial and/or residential interior space is generated by obtaining arrays of patterns that correspond to user search criteria, from a stored set of patterns for interior design surface treatments. The arrays of patterns are displayed on a computer display. Each array of patterns corresponds to a surface treatment product type. Subarrays of patterns then are generated, each subarray corresponding to a surface treatment product type. The subarrays of patterns are generated in response to selection by a user from the corresponding array of patterns for the corresponding surface treatment type. Finally, at least one pattern from at least two of the subarrays of patterns are combined to produce a storyboard of interior design surface treatments for an interior space.Type: GrantFiled: January 11, 2000Date of Patent: October 1, 2002Assignee: BlueBolt Networks, Inc.Inventor: Lauranne P.

Patent number: 6037928Abstract: The present disclosure is directed to a system for providing restrained, streamlined access to a computerized information source. The system--which works in association with a multipurpose computer--includes a discrete article, such as an advertising specialty like a mouse pad, having facilities to receive a user input and, in turn, generate a unique predetermined signal based on the input. The system further includes software for configuring the computer to respond to each unique predetermined signal by executing one or more commands, as selected and stored within the software. Each configuration can be dynamically locked such that the commands to be executed upon the unique input are not alterable without an authorization mechanism, such as a password. The software also responds to receipt of one of the unique predetermined signals by executing the commands associated with the received signal. A method for performing same is also disclosed.Type: GrantFiled: November 13, 1997Date of Patent: March 14, 2000Assignee: Imageworks Manufacturing, Inc.Inventors: Jon Nachinson, Richard Krebs, Richard Watson, Thomas Becker, Gregory Morton

Patent number: 5821924Abstract: A system for lowering the power output of a computer peripheral device connected to a host computer during periods of inactivity of the host or the peripheral device senses a power management command at the peripheral device generated at the host computer. Time sensing means at the host senses inactivity, and gerating circuitry generates a power-management command. Detection circuitry in the peripheral device senses the power-management command, and controls power-using circuitry in the peripheral device in response. In an embodiment applicable to peripherals having a microprocessor, the system may be incorporated entirely in software at the host and the peripheral device. In dumb devices, the system requires add-in and/or add-on apparatus cooperating with software.Type: GrantFiled: October 26, 1995Date of Patent: October 13, 1998Assignee: Elonex I.P.

Patent number: 5805140Abstract: A method and apparatus for interfacing the motion of a user-manipulable object with an electrical or computer system includes a user object physically contacted by a user. A gimbal mechanism is coupled to the user object, such as a joystick or a medical tool, and provides at least two degrees of freedom to the user object. The gimbal mechanism preferably includes multiple members, at least two of which are formed as a unitary member which provides flex between the selected members. An actuator applies a force along a degree of freedom to the user object in response to electrical signals produced by the computer system. A sensor detects a position of the user object along the degree of freedom and outputs sensor signals to the computer system.Type: GrantFiled: November 17, 1995Date of Patent: September 8, 1998Assignee: Immersion CorporationInventors: Louis B.

Patent number: 5767833Abstract: A method and system for providing external bit map support to device drivers coupled to a data processing system are disclosed. The data processing system includes a central processing unit, memory, user output device, and a user input device. The method and system also provide outputting of an image under a graphical user interface on the display device. In implementing the improved external bit map support, the system and method generate an image through the graphical user interface in device independent bits format and then determine whether the image is to be supported in an external bit map format. If the image is to be supported in an external bit map form, the system determines the level of required resolution for supporting that image and then converts that image to the external bit map format at that desired level of resolution. The desired level of resolution is selectable from either 24 bits per PEL (bpp), 8 bpp or 4 bpp.Type: GrantFiled: June 28, 1995Date of Patent: June 16, 1998Assignee: International Business Machines CorporationInventors: Mark W.

Patent number: 5572234Abstract: A method for converting from one display element density to a different display element density. In order to convert from one pixel density to a different density, each pixel in a particular position in a first pixel density must be associated with a pixel or pixels in a corresponding position in a different pixel density. The present invention tracks the cumulative pixel position error introduced for the conversion of each pixel from one input density to a different output density. By tracking a cumulative pixel conversion error, each subsequent pixel conversion is optimized based on the conversion of all prior pixels. In this manner, a more accurate pixel density conversion may be achieved regardless of mid-row density variations. Specifically, the present invention achieves an accuracy of a pixel position error of no more than one-half the distance between the centers of two adjacent output density pixels.Type: GrantFiled: August 7, 1995Date of Patent: November 5, 1996Assignee: Intel CorporationInventor: Wayne L. Dohnal
