Abstract: A Kelvin sensed hot-wire anemometer includes four electrically conductive pins and a filament welded to all four pins, preferably using a single filament. A current source is coupled to the two innermost pins so as to provide current flow in the segment of filament between the two innermost pins. The two outermost pins are coupled to a high impedance voltage sense amplifier that senses the voltage drop across the energized segment of filament between the two innermost pins. The resistance of the filament is determined based on the current provided to the filament and the measured voltage. The Kelvin sensed hot-wire anemometer can be used in a number of applications, including, but not limited to medical devices that measure gas flow rates during inhalation and exhalation.

Abstract: An electric power steering device enabled to surely detect a fault of its motor current detector circuit by avoiding the disturbance by an electrically insulated oxide film formed on the contact surface between the commutator and the brush of the motor. An ignition key is turned on, then the motor applied voltage is increased with time to break the oxide film so that the motor current flows normally. The estimated motor current is then compared with the detected motor current. When the absolute value of the difference between those estimated motor current and detected motor currents is over a predetermined limit value, it is determined that the motor current detection circuit is defective. It is also possible to break the oxide film by integrating each difference between the motor current command value and the detected motor current value, thereby increasing the current control value step by step and increase voltage applied to the motor.
Abstract: Disclosed herein is a microchip provided with a specimen flow pass, a reagent flow pass, a confluence flow pass all of which are fine flow passes. The specimen flow pass allows specimen to flow toward one end thereof. The reagent flow pass is connected to that end of the specimen flow pass and allows at least one reagent to flow for reaction with the specimen. The confluence flow pass extends from that end of the specimen flow pass and allows the confluent specimen and reagent to flow. A sensing portion is assigned near or at the confluence flow pass, and the reaction of the specimen and the reagent is capable of being detected or observed there. Further to this, the microchip comprises a force applying means for reciprocally moving the specimen and the reagent at the sensing portion.
Abstract: A solid-state, two-dimensional image sensing device having a matrix of pixels each of which employs a photosensor that generates a photocurrent and a MOS circuit which outputs a signal proportional to the logarithm of the integral over time of the photocurrent. The sensor includes an integration control switching device so that all pixels in the array have equal integration time. The sensor integrates the signal for each pixel for a period of time and stores the integrated signal in a pixel signal storage location. To read out the stored signal each pixel includes an amplifier to increase the signal during read out. The sensor further accumulates signal in either a MOS transistor pn-junction or a secondary pixel storage location during a time that the integrated pixel signal is being read out so that image information can be collected continuously even while the integrated pixel signal for each pixel is being read.

Abstract: According to the method and apparatus, light beams directed toward virtual visual points are detected from among light beams emitted from or reflected on the surface of an object. The detection is effected by an image pickup device in a plurality of positions lying on a virtual closed surface with which the object is enclosed. The detected light beams are converted into image pickup signals, which are delivered to a display device adapted to display an image toward a visual point of an observer standing or sitting in a place different from a place where any of the virtual visual points is disposed. The image is displayed in such a manner as if light beams were emitted toward the visual point of the observer from various points on the surface of a virtual object disposed in a virtual position corresponding to the relative positions of the real object and any of the virtual visual points.
