A lower troposphere Radar: 1.3-GHz active phased-array type wind profiler with RASS

Abstract: We have developed an atmospheric radar (wind profiler) for lower tropospheric observations (Lower Troposphere Radar: LTR), based on the 1357.5-MHz boundary layer radar (BLR), which we previously developed mainly for observations of the atmospheric boundary layer. System gain of this radar is improved due to newly developed large-sized active phased-array antenna, active transmitting modules with higher output power, and pulse compression technique. It has the following functions: an antenna gain of 33 dBi is obtained with a 4 m × 4 m active phased array antenna which has 96 antenna subelements, a peak output power of 2 kW is obtained by 24 active transmitting modules, and maximum S/N is improved 8 times by using a pulse compression technique which uses 8-bit optimized coding developed by Spano and Ghebrebrhan (1996c). The LTR is the first active phased-array 1.3 GHz-band wind profiler radar. It is possible to vary the beam direction by electronically steering the zenith angle within 45°. Atmospheric winds in the lower troposphere, including the atmospheric boundary layer, are obtained with high time and height resolutions in real time. Observations of atmospheric temperature are also possible using the radio acoustic sounding system (RASS) technique with speaker horns. We have confirmed LTR’s potential as a reliable tool for atmospheric observations, using simultaneous observation results with the MU (Middle and Upper atmosphere) radar, a Doppler sodar, and a radiosonde.

Motion-based text input

Abstract: A method generates input text with a pointing device at a distance from a writing surface. Motion information of a mobile coordinate frame of the pointing device is sensed relative to a stationary coordinate frame of the writing surface using a motion sensor configured to track motion of the pointing device. The input text is then determined from the motion information. A projection of a track of the motion of the pointing device on the writing surface can also be determined from the motion information, and the track can be displayed on the writing surface as the input text.

Method and device for detecting music segment, and method and device for recording data

Abstract: The present invention is to provide a method of efficiently detecting music scenes from television broadcasts. A music-segment detection method according to the present invention includes a data input step of inputting data including an audio and video signals; a plurality of candidate-music-segment detection steps of detecting candidate music-segments from the audio signal based on criteria different from each other; and a music-segment detection step of detecting a music segment based on the plurality of detected candidate music-segments. Thereby, high detection accuracy can be ensured for a wide variety of music with various tones, such as rock, popular ballad, and classic.

DC/DC power conversion device

Abstract: A DC/DC power conversion device with smoothing capacitors including three column circuits share the smoothing capacitors to be connected in parallel, each column circuit have a plurality of circuits connected in series where two MOSFETs are connected in series between both ends of respective smoothing capacitors and LC serial bodies of capacitors and inductors with the same resonant cycle are disposed between the circuits at two middle terminals. Driving signals for the respective column circuits have the same driving cycle identical with the resonant cycle of the LC serial bodies, and are out of phase with each other by 2π/3(rad), and thus charge-discharge currents towards the smoothing capacitors are circulated among the column circuits and ripple currents flowing through the smoothing capacitors are reduced.

Display holding device

Abstract: Disclosed is a display holding device which retains one or more displays in such a way that they move laterally and smoothly. The display holding device, which is installed between at least one display and a supporting body supporting the display, includes (1) a guide mechanism secured to the supporting body, and (2) at least one holding mechanism for transmitting, to the guide mechanism, a moment due to weight of the display, and being secured to the display. In addition, the guide mechanism includes (a) a guide portion spanning laterally, and (b) a stopper placed along the guide portion. The holding mechanism includes (c) a slider mating with the guide portion in a slidable manner, and (d) a contact portion facing the stopper. The stopper blocks the contact portion from being displaced in the direction of the moment, and allows it to be displaced in the opposite direction.
