Title: Wireless communication system and wireless communication device
Inventor: SUWA YUTAKA
IPC: H04W56/00
Filed: 2011-11-10
Abstract: In a system that conducts a WiFi communication, if plural terminals are present, timing when the terminals communicate with the base station collides with each other, and it becomes necessary to wait for transmitting data, or a time during which a receiving unit of the terminals is active becomes long to deteriorate a power saving efficiency. According to the present invention, a DECT communication unit and a WiFi communication unit are both provided in each base station, one of a plurality of base stations is configured as a master base station, a timing of the DECT communication of each base station is synchronized with each other according to a control signal transmitted by the DECT communication unit in the master base station, and each base station corrects a timer of the WiFi communication unit according to timer information notified by a control signal of the DECT. As a result, each terminal can precisely predict the transmission timing of the WiFi beacon issued by each base station, and reduce the receiving operation to a minimum time as required.

Title: Device with paired rotators acting as a pump or as a fluid motor.
Inventor: KANTNER HAROLD H
IPC: B62M1/06
Filed: 1980-09-10
Abstract: The fluid-power converter of the present invention is a pump-motor having matched rollers and matched gears arranged to provide seals and displacement paths. The pump-motor includes a plurality of rotators in series-contact to define a plurality of fluid-pressure zones. At least one of the rotators has a smooth surface and at least another of the rotators has a gear-like surface. A smooth rotator and a gear-like rotator are in contact with each other to define therebetween a displacement path whereby fluid is transferred from one zone to another zone, and at least one pair of similar rotators are in contact with each other to provide therebetween (and between the pressure zones) a seal to insure fluid-flow in only one direction between the zones at a given moment. A pair of the converters, one operating as a pump and the other as a motor, provide the motive power with free-wheeling and coaster-brake features for small vehicles such as bicycles, wheelchairs, and golf carts.

Title: System and method for predicting ventricular tachycardia.
Inventor: NETRAVALI ARUN NARAYAN
IPC: A61B5/363
Filed: 1983-02-14
Abstract: An electrocardiology system and method for predicting potential ventricular tachycardia in a patient. Each of a patient's X, Y, and Z electrocardiographic signals (100, 101, 102) are converted from analog to digital values (120), and stored (130), and are then processed to select only normal or typical QRS waveforms. The selected waveforms are signal averaged over several hundred beats to obtain a relatively noise-free composite QRS. The latter portions of the X, Y and Z digital QRS signals are then applied in either forward or reverse time order to an adaptive finite impulse response high pass filter (170). The finite impulse response filter processing enables the ringing artifact to be eliminated from the filter's output. The resulting filtered outputs are combined to create a composite filtered QRS waveform. The last (40) (or so) milliseconds of the filtered composite is isolated and measured to obtain an indication of the level of high frequency energy content indicative of a propensity for episodes of ventricular tachycardia (200). The overall QRS waveform is also processed in the same time order to determine its total duration (210) which provides a second indication of propensity for Ventricular Tachycardia.

Abstract: Laser excimeur à oscillation à bande étroite utilisant une grille de diffraction en tant qu'élément sélecteur de longueur d'onde, particulièrement indiqué pour une source de lumière d'un dispositif d'alignement du type à réduction. La grille utilisée dans le laser susmentionné est positionnée de sorte que la direction de ses lignes est presque perpendiculaire à la direction de la décharge du laser. Lorsque l'on utilise un expandeur de faisceau pour diffuser le faisceau laser tombant sur la grille, l'expandeur est disposé de sorte que la direction de diffusion du faisceau est presque perpendiculaire à celle de décharge du laser. En outre, lorsqu'on doit utiliser une ouverture dans le résonateur optique, l'ouverture est placée de sorte que le sens de la longueur puisse être parallèle à la direction de décharge du laser. En outre, le miroir antérieur du résonateur optique est cylindrique, et son axe mécanique est parallèle à la direction de décharge du laser. Cet agencement permet de produire un appareil laser excimeur à oscillation à bande étroite présentant un très grand rendement et une excellente durée.
Patent EP-0471062-A4 (EP)
Title: Method to use a reaction by-product as a calibrator for enzymatic assays
IPC: C12Q1/52
Filed: 1991-02-27
Abstract: A method to use a reaction by-product as a calibrator in an automated enzymatic assay is described. In particular, the reaction by-product pyruvate is used as an instrument calibration standard to measure the activity of alanine aminotransferase. Use of this method eliminates errors due to inaccurate pipetting and corrects for small optical deviations from the wavelength of interest in the instrument. Left uncorrected, pipetting error and optical deviation negatively impact the accuracy of the enzyme activity calculation. In the fluorescence mode, calibration with a pyruvate standard also eliminates having to use unstable NADH standards. The pyruvate calibration standard of this invention is shown to be stable in standard stability testing. This method can be extended to a number of other automated enzymatic assays. Like alanine aminotransferase, the accuracy of the activity calculation for other enzymes should be increased by use of this procedure.

The grill (21') is comprised of a monolayer of polygonal cells in an array of cells, each cell being bounded by planar walls having a depth "L" interstitial thickness "T" and a diameter or major dimension "D", wherein the interstitial depth L is short enough such that the planar walls do not act as vanes to significantly affect directionality of the air, the interstitial thickness T has a value such that the impedance to air flow is low, and the length to diameter ratio L/D is no greater than about 0.7 and no less than about 0.3, such that the relative visual opacity of the grill when viewed from any angle is high. The open cell area Ao must be at least about 76% of the available (total) area to obtain an acceptable 1800 ft/min face velocity at a blower pressure of 0.24 inches H2O. The upstream directionality control mechanism includes a disc intruder (224). The intruder member has axially projecting control shaft (35') which carries a spherical member (37') frictionally received in a spherical socket (38') such that the control shaft can easily be manually manipulated.

Abstract: An optical information recording medium which has a reflecting layer for optically reading information signals. The medium is composed of a plastic substrate. The substrate is colored with a dye so that the kind of information recorded on the medium can be visually confirmed at a glance whether the information is, for example, a game program, musical information, or other kinds of information. Usually, the optical system of a reader is affected and the reader cannot read data easily when such an impurity as the dye, etc., is mixed in the substrate. The influence on the optical system is eliminated because the particle size of the dye is reduced to 50  mu m. <IMAGE>
