Publication number: 20040222977Abstract: Notifications to computer users are provided via indicators such as lights. The indicators are controlled according to rules, to convey computer-related state information to users in a consistent manner. Locations of visible indicators are chosen to facilitate easy viewing. The rules dictate colors and/or illumination pattern components that together provide users with important computer-related information. For example, colors are assigned to types of information, and illumination patterns generally to behavior-related information. Colors may be combined in various illumination patterns. In one implementation, many or all of the visible indicators may be grouped together on a single control panel from rapid viewing. Alternatively, the visible indicators may be grouped by function or other logical arrangement, such as on the keyboard and/or frame of a monitor. Alternative light sources that illuminate the system (e.g.Type: ApplicationFiled: May 5, 2003Publication date: November 11, 2004Inventors: Eric Gould Bear, Chad Magendanz, Aditha May Adams, Carl Ledbetter, Steve Kaneko

Publication number: 20040222978Abstract: A control and communications panel that provides users with an easy way to perform computing tasks. The panel may be located in any convenient location, such as in a location that the user can easily see and reach. The control and communications panel provides various controls such as buttons corresponding to computing tasks, including program-related and communications-related tasks. When operated, each control notifies the operating system (or other program) of a state change, and control handling logic processes the state data to take an appropriate action. Indicators such as LEDs related to the controls convey state information to users. USB ports and/or media drives or storage media may be included in the control and communications panel.Type: ApplicationFiled: May 5, 2003Publication date: November 11, 2004Inventors: Eric Gould Bear, Chad Magendanz, Aditha May Adams, Carl Ledbetter, Steve Kaneko

Patent number: 6795043Abstract: A first PLL circuit (100) receives a flyback pulse (VFB) as a reference signal and outputs a clock signal (CLK1), and a delay circuit (200) outputs a flyback delay signal (VFBD) having a predetermined delay time corresponding to the amount of horizontal movement on a screen. A second PLL circuit (300) receives a horizontal synchronizing signal (VHSYNC) and the flyback delay signal (VFBD) as a reference signal and a compared signal, respectively, and generates a horizontal drive pulse (VHD). A deflection yoke (12) receives the horizontal drive pulse (VHD) and generates a flyback pulse, and a step-down transformer circuit (16) outputs the flyback pulse (VFB) whose voltage is lowered. With this constitution, it becomes possible to generate a stable horizontal drive pulse which causes no jitter on the screen when a PIN balance correction, a KEY balance correction and a horizontal position adjustment of a CRT are performed by digital processing.Type: GrantFiled: April 2, 2001Date of Patent: September 21, 2004Assignee: Mitsubishi Denki Kabushiki KaishaInventor: Tatsuo Shibata

Patent number: 6690339Abstract: A method and a circuit arrangement for controlling the operating point of a cathode ray tube (3) for use in image technology applications. A video signal (1) is supplied to both the tube (3) and to a cathode ray tube model (2), which the model (2) uses to emulate a beam current. From the emulated beam current and a measured beam current, a characteristic quantity for adjusting the operating point is determined.Type: GrantFiled: June 7, 2001Date of Patent: February 10, 2004Assignee: Siemens AktiengesellschaftInventors: Klaus Burkhardt, Uwe Nagel, Erich Schaefer, Hartmut Schulz

Patent number: 6657623Abstract: In a method and apparatus for transmitting a video signal, parallel digital video signals output from a graphic controller of a computer are transmitted to a driver of a cathode ray tube monitor by converting the parallel digital video signals to serial digital video signals, transmitting the converted serial digital video signals to the cathode ray tube monitor via a cable, converting the transmitted serial digital video signals to serial analog video signals, and inputting the converted serial analog video signals to the driver of the cathode ray tube monitor.Type: GrantFiled: March 22, 2000Date of Patent: December 2, 2003Assignee: SamSung Electronics Co., Ltd.Inventor: Hyun-kuk Shin

Patent number: 6625666Abstract: An operation-recording type system for controlling a display data channel (DDC) monitor utilizes a control method wherein information of externally inputted signals is recorded in a storage device upon receipt of externally inputted signals; an operation corresponding to the externally inputted signals is carried out by a microcomputer; the operation corresponding to the externally inputted signals is recorded in the storage device; and the externally inputted signals and the corresponding microcomputer operations are recorded in the storage device. Therefore, the user of the monitor can easily identify the cause of abnormal operation, thereby making it easy to correct errors.Type: GrantFiled: April 25, 2000Date of Patent: September 23, 2003Assignee: Samsung Electronics Co., Ltd.Inventor: Hong-Jae Kim

Patent number: 6577285Abstract: A gamma corrector inputs a primary color signal as an image signal to each of the differential amplifiers which are connected in parallel to each other and mixes a plurality of output signals which are outputted from the four differential amplifiers to output an image signal to which a plurality of gamma correction is applied. Each of the differential amplifiers amplifies and outputs the inputted primary color signal with a different gain characteristic so that the gain characteristic of the signal obtained by mixing the output signals varies at two inflection points. The two-point gamma correction is applied to the inputted primary color signal so that a signal level at the side of a black level is turned down and the signal level at the side of a white level is turned up.Type: GrantFiled: October 14, 1999Date of Patent: June 10, 2003Assignee: Sony CorporationInventors: Hitoshi Motonakano, Shozo Mitarai

Patent number: 6570546Abstract: Monitors for use in a tiled monitor system include adjacent monitor detectors arranged to detect the presence of corresponding adjacent monitor detectors on adjacent monitors so that the physical arrangements of the tiled monitors can be determined without user intervention. Similarly, orientation sensors are provided in each monitor so that their orientation—landscape vs. portrait—can be determined by the monitor without user intervention and reported to the video controller.Type: GrantFiled: October 31, 1998Date of Patent: May 27, 2003Assignee: Duke UniversityInventors: Mark W.
