Patent number: 6995750Abstract: A pointing device is provided for reporting motion information about the pointing device. Counts representing movement in two dimensions are processed so that a packet data stream may accommodate the motion information. One aspect of the invention utilizes the value of count to determine whether compression of the motion information should be performed. When it is determined that compression should be performed, a compression function is selected, the count is processed by the compression function, and an indicator is set to indicate that the count is processed by the compression function. Reporting information, which includes the processed count and the indicator, is then transmitted to computer system. A user input interface that is associated with the computer system recovers the counts using appropriate inverse functions in accordance with the indicators.Type: GrantFiled: March 19, 2003Date of Patent: February 7, 2006Assignee: Microsoft CorporationInventors: Mihai Albulet, Gary Rensberger

Patent number: 6567072Abstract: Characters are easily input using a direction indicating device. The device provides a direction indicating device which outputs a rotated direction of lowering, or the direction inclination and its strength, a display device, a key input means, a memory that stores a plurality of character sets, and a control means which selects characters a character set and characters comprising this character set which are stored in memory according to the output of the direction indicating device, and displays them on the display device, and which accepts the output of the direction indicating device as circumferential position information, and selects a specified character from a chart of characters that associates the previously provided position information with the output of the direction indicating device.Type: GrantFiled: June 22, 1999Date of Patent: May 20, 2003Assignee: NEC CorporationInventor: Mitsuhiro Watanabe

Publication number: 20030090470Abstract: An optoelectronic keypad and a method for controlling an optoelectronic keypad for a measuring instrument, require a transparent touch screen, at least two touch-sensitive control buttons, at least two light emitters and at least two photodetectors, where said control buttons are located next to each other on one side of the surface of the touch-screen, the light emitters and the photodetectors are situated next to each other on the other side of the touch screen and each one control button, light emitter and photodetector are functionally associated with one another in a way as to constitute one action key, whereby pressing the control button of an action key causes the light emanating from the light emitter of that action key to be reflected at the actuated key and to impinge on the photodetector of that key.Type: ApplicationFiled: September 13, 2002Publication date: May 15, 2003Inventors: Jurgen Wolter, Wolfgang Stelz, Detlef Ludwig

Patent number: 6564254Abstract: When a user selects an arbitrary symbol 75 (word, phrase, sentence, graphic, image, etc.) from an arbitrary application 3 on a client computer 3, and copies this symbol 75 to a clipboard 79, a linker 23, being a terminate-and-stay-resident-type process, automatically captures that symbol 81 from the clipboard 79. Similarly, when a user types at a keyboard from an arbitrary application 207, those typed characters are first passed to an input method editor 201, where they are temporarily stored within a buffer 211, and when the user enters a prescribed “okay” key sequence the characters within that buffer 211 are converted as necessary and passed to the application 207, but if the user enters a prescribed “link” key sequence, a character string determining component 213 of the input method editor 201 passes the characters within the buffer 211 to a linker 209. In either case, the linker 23 sends the captured symbol to a URL server 5.Type: GrantFiled: October 4, 1999Date of Patent: May 13, 2003Assignee: Dream Technologies CorporationInventors: Wataru Shoji, Daisuke Tabuchi, Ichiro Nakajima, Gabriele Gramlich

Publication number: 20030067758Abstract: A keyboard is provided having illuminating keys. The keyboard includes a light channeling membrane and key members constructed at least partially of translucent material so that light produced from a light source is channeled upwardly to the upper surfaces of the key members. The light source may include LED or LEC systems in adjoining relationship to the light channeling membrane or light pipe. In a preferred embodiment, the light source is constructed of a substantially planar illuminescent sheet which underlies the light channeling membrane. In an alternative preferred embodiment, a light pipe is constructed to illuminate light laterally along a portion of its length to illuminate a plurality of key members.Type: ApplicationFiled: November 14, 2002Publication date: April 10, 2003Inventor: Michael Shipman

Patent number: 6535202Abstract: A display screen switch of the present invention includes: a plate-like case arranged on a display screen and provided with a transmit-light window part in which switch information displayed on the display screen is transmitted; a switch body fixed to the case; a cover arranged on an upper side of the case and having a hole part; a transmit operational member including a transparent display part which transmits a visible light and on which the switch information is displayed, and a switch push-down part which makes the switch body operate; and an elastic member interposed between the transmit operational member and the case along a circumference part of the transmit operational member. The transmit operational member being arranged such that the transparent display part and the switch push-down part are arranged in a protruding way from the hole part between the cover and the case. Especially, the elastic member and the transmit operational member are bonded by an adhesive.Type: GrantFiled: October 5, 2000Date of Patent: March 18, 2003Assignee: Yazaki CorporationInventors: Takeyuki Amari, Yoshiyuki Furuya

Patent number: 6525677Abstract: An optical laser numeric keypad (100) provides a digital signal indicative of which of a plurality of key locations is selected. The optical laser numeric keypad (100) comprises a plurality of optical sensors (132 and 134) each configured to respond to a change in a received light quantity and to provide an electrical signal in response to a selection of a key at a key location. The received light quantity of at least one of the plurality of optical sensors (132 and 134) is changeable by selection of a key location.Type: GrantFiled: August 28, 2000Date of Patent: February 25, 2003Assignee: Motorola, Inc.Inventor: George A. Printzis

Patent number: 6515653Abstract: A keyboard control system that contains a manufacturer's identification code and a multiple selection matrix. This invention utilizes all the existing LED leads on a keyboard controller. Using the period between initial setting and normal operation together with triggering signals, user or customer is able to pick up suitable data from a single keyboard controller. In addition, the invention is capable of using the same leads for connecting to external serial EEPROM so that new data not included among the preset data within the keyboard controller can still be input to the controller. Furthermore, the same type of technique can be used to increase the number of combinations in different application areas as long as more keyboard controller input/output ports are available.Type: GrantFiled: February 20, 2001Date of Patent: February 4, 2003Assignee: Winbond Electronics Corp.Inventors: Chao-Ting Kao, Chin-Cheng Shen

Patent number: 6498600Abstract: An electronic device includes a keypad and a sensor that indicates proximity of a user to the electronic device, whereupon the keys of the keypad are illuminated. In particular, when the distance between the user and the sensor is less than a predetermined threshold, the keypad is illuminated in anticipation of the user providing keypad input to the electronic device. The sensor can be an infrared, an ultrasonic or a capacitive sensor. Alternately, the sensor can indicate contact between the user and the sensor, wherein the contact does not provide keypad input to the electronic device, for example, when the user touches but does not push a key of the keypad.Type: GrantFiled: August 18, 1999Date of Patent: December 24, 2002Assignee: Ericsson Inc.Inventors: Scott L.
