Publication number: 20070115257Abstract: A signal generator displays signal patterns according to a sequence and displays a current output or waiting signal pattern distinctively from other signal patterns after the start of signal output operation. Identifiers such as index numbers may be related to the respective signal patterns and displayed. The identifier of the current output or waiting signal pattern is blinked to distinguish the signal pattern from other signal patterns. Alternately, the color of the current output or waiting signal pattern may be reversed or highlighted to easily identify the signal pattern from the other signal patterns.Type: ApplicationFiled: November 17, 2006Publication date: May 24, 2007Inventors: Toshio Sugiyama, Toru Takai

Publication number: 20070115258Abstract: A novel personal electronic device includes a first (embedded) and second (non-embedded) processors including associated operating systems and functions. In one aspect, the first processor performs relatively limited functions, while the second processor performs relatively broader functions under control of the first processor. Often the second processor requires more power than the first processor and is selectively operated by the first processor to minimize overall power consumption. Protocols for functions to be performed by the second processor may be provided directly to the second processor and processed by the second processor. In another aspect, a display controller is designed to interface with both processors. In another aspect, the operating systems work with one another. In another aspect, the first processor employs a thermal control program. Advantages of the invention include a broad array of functions performed by a relatively small personal electronic device.Type: ApplicationFiled: January 17, 2007Publication date: May 24, 2007Applicant: DUALCOR TECHNOLOGIES, INC.Inventors: Bryan Cupps, Timothy Glass

Publication number: 20070115259Abstract: A receiving structure for a receiver of a wireless mouse is disclosed. An accommodating slot for receiving a receiver is disposed on rear end of an upper cover of a wireless mouse. And a vertical pin on an arm is arranged on center line of a bottom plate of the accommodating slot. The vertical pin moves elastically and turns back automatically while being forced. An elastic member and a limit switch for power control are disposed in front of the accommodating slot. Two consecutive front and rear stopping plates corresponding to the vertical pin are disposed on bottom of the receiver and two sloped guiding surfaces in opposite directions are arranged on the front and rear stopping plates respectively. When the receiver plugs into the accommodating slot, the sloped guiding surface of the front stopping plate presses the pin to move outwards, away from the central line and then leaves the rear end of the sloped guiding surface and locks into the arc of the front stopping plate.Type: ApplicationFiled: November 23, 2005Publication date: May 24, 2007Inventor: Min-Fang Pai

Virtual Keyboard input system using three-dimensional motion detection by variable focal length lens
Publication number: 20070115261Abstract: A virtual keyboard input system using three-dimensional motion detecting by variable focal length MMAL is provided. The compactness of the virtual keyboard input system is accomplished by the variable focal length MMAL performing three-dimensional imaging function. Since the three-dimensional imaging process occurs in a very short time scale, the system can determine the motion of the input by the user and track the motion of the user in real-time based response. Image processor can determine which input is occurred at the moment and the time-dependent profile of the motion itself. The input system gives an output just like a conventional keyboard and a mouse system.Type: ApplicationFiled: November 23, 2005Publication date: May 24, 2007Applicants: Stereo Display, Inc., Angstrom, Inc.Inventors: Gyoung Cho, Cheong Seo -
Publication number: 20070115262Abstract: Provided is an apparatus and method for inputting characters in a mobile communication terminal in which at least one character is mapped to each key An input key including a desired character is selected, a sequence key corresponding to the mapping sequence of the desired character is selected, and the character designated by the selected sequence key is displayed. Accordingly, it is possible to conveniently input the desired key by pressing only two keys, i.e., the input key and the sequence key, without having to press a separate key or wait for a predetermined time after pressing the input key.Type: ApplicationFiled: November 22, 2006Publication date: May 24, 2007Applicant: Samsung Electronics Co., Ltd.Inventor: Byoung-Seoup Moon
