IPC: H04B1/16
Filed: 2001-08-24
Abstract: PROBLEM TO BE SOLVED: To provide an OFDM transmitter and an OFDM receiver capable of ensuring sufficient linearity in performance even if the components with poor linearity are employed. SOLUTION: A OFDM transmitter is provided with a serial/parallel converting part 1, an inverse fast Fourier transform (IFFT) 2, a guard interval addition part 3, a nonlinear correction part 4, a low pass filter (LPF) 5, a D/A converter (DAC) 6, an orthogonal modulation 7, a local oscillator 8, an intermediate frequency amplifier (IF) 9, and a high frequency amplifier (RF) 10. The nonlinear correction part performs correction by using correction functions before processing in IFFT 2 so that a nonlinear characteristic of input/output signal resulting from a nonlinear distortion which are caused in each part of the OFDM transmission approaches a linear characteristic. Thereby even if the components with poor linearity are used, the linear operation is ensured as the entire OFDM transmitter.

Title: Wireless mobile communication network and information communication method therein and mobile node
Inventor: POON TOMMY C
IPC: H04L12/56
Filed: 2001-08-31
Abstract: PROBLEM TO BE SOLVED: To share a network resource among a plurality of users and to improve performance and throughput, in a mobile communication network. SOLUTION: In the wireless mobile communication network, the mobile node of a cellular telephone or other types of the mobile transmitter/receiver can directly and mutually communicate with a fixed base station. Communication capability between the mobiles is used through the formation of a local link transferring a message with the request of the base station by the node having an excess processing and bandwidth capacity. The formation of the local link is adaptive and does not require a central controller. When information is directly communicated with the base station via the network link, the node is constituted as a large node. Information is communicated indirectly with the base station via the direct local link with one of the large nodes.  For forming the mobile network which is locally linked in the wireless mobile communication network, the node is constituted as the small one.

Title: Calibration method
Inventor: BOWDLER ANDREW R
IPC: G01N27/62
Filed: 2001-09-05
Abstract: PROBLEM TO BE SOLVED: To compensate an effect of mass offset in a prior-art calibration technique. SOLUTION: The above purpose can be achieved either by correcting the offset or by allocating mass to peaks in such a manner as to avoid the offset. According to the first mode, a method is provided for calibrating a reflectron time-of-flight(TOF) mass spectrometer by using a spectrum produced by fragment ions and this method is characterized in that the mass of the fragment ions is allocated by using only a mono-isotopic peak. In other words, a value corresponding to the mass of the fragment ions used for calibration is allocated by using only the fragment-ion mono-isotopic peak, and the above value is used to calibrate the mass spectrometer.

IPC: G06F3/0346
Filed: 2001-09-12
Abstract: PROBLEM TO BE SOLVED: To construct visual axis measuring techniques for measuring the direction of gazing without the user being stressed or wearing a special device. SOLUTION: An apparent pupil position is detected from an image taken with a camera and the direction of refraction of light going from the camera to the apparent pupil position is calculated to determine contour coordinates located at a specific distance from the center of curvature of the cornea along the direction of refraction, to thereby estimate the actual pupil position. A reflected image of external light on the surface of the cornea is detected to detect the position of the cornea's center of curvature which is located on a straight line passing through the center of the camera and the reflected image and which is away from the reflected image by a distance equal to the radius of curvature of the cornea.  The center of the pupil is detected from the actual pupil position and the user's visual axis is calculated on the basis of a straight line connecting the center of the pupil to the center of curvature of the cornea. The conversion term of the visual axis is calculated from the coordinates of a plurality of reference points and from the visual axis calculated at the time when the user gazes at the reference points, and the visual line is corrected using the conversion term.

Title: Automatic faucet
Inventor: ARAKAWA MASAFUMI
IPC: E03C1/05
Filed: 2001-09-13
Abstract: PROBLEM TO BE SOLVED: To provide an automatic faucet having the same usability with the manual faucet, and switchable to a manual water discharge state or an automatic water discharge state. SOLUTION: This automatic faucet 1 controls opening-closing of an electrically operated valve 4 by a signal from a human body detecting sensor 13 by arranging the electrically operated valve 15 and a manual valve 4 in series in the middle of a waterway of the faucet. The electrically operated valve 15 closes only when the manual valve 4 opens and the signal from the human body detecting sensor 13 is not detected, and maintains opening except for that. The manual valve 4 is opened, and when hands are extended to a water discharge port 10 in this state, the human body detecting sensor 13 detects this so that water is automatically discharged. When the human body is not detected in an opening state of the manual valve 4, the electrically operated valve 15 closes, and is put in a water cut-off state. While, when the electrically operated valve 15 cannot be used by power failure, since the valve is put in a still opening state, a water discharge state and the water cut-off state can be switched by opening-closing operation of the manual valve 4.

Title: Communication controller compatible with fault and communication control method compatible with the fault
Inventor: KANEDA NORIKO
IPC: H04L12/40
Filed: 2001-09-14
Abstract: PROBLEM TO BE SOLVED: To provide a communication controller compatible with a fault that can recognize the occurrence of the fault without the need for useless communication on the occurrence of the fault in a terminal in a network. SOLUTION: A fault occurrence detection section 108 and a fault restoration detection section 109 of a terminal 106 detect the occurrence of a fault or the restoration of a fault in the inside of the terminal itself. A fault frame assembling section 107 assembles a frame, with respect to the fault on the basis of the result of detection, and then a communication section 102 simultaneously broadcasts the frame to a transmission line. Each terminal, however, recognizing the occurrence of the fault of the other terminal 106 by a fault frame interpret section 110, suppresses the transmission of frames to the faulty terminal until the fault is restored.
