摘要： An optical displacement measuring system using a triangulation comprises a light projecting unit for emitting to an object a light beam which is amplitude-modulated by a reference signal having a predetermined period, a light receiving unit for receiving light reflected back from the object and providing a pair of position signals, and a control signal generator for providing first and second control signals in synchronism with the reference signal. The position signals are processed by a switching unit in a time sharing manner according to the first control signal to obtain a first composite signal, in which the position signals occur alternately every integral number of the period of the reference signal. The first composite signal is amplified by a single amplifier at a desired amplification rate, and then sent to a distance determining unit, in which the polarity of the first composite signal is periodically reversed according to the second control signal to obtain a second composite signal, and a distance signal indicative of a distance between the light projecting unit and the object is determined from the second composite signal.

摘要： A laser diode 11 irradiates an object 3 with beam light modulated in an appropriate cycle. A position detection element 21 outputs a pair of position signals responsive to the position of a light reception spot and a processing section finds a distance to the object 3 based on the position signals. The processing section comprises a modulation control circuit 34 for irradiating the object 3 with beam light as many times as appropriate for performing distance measurement operation, then stopping the distance measurement operation and generating modulation control output indicating the operation stop, and upon reception of modulation control input indicating the operation start from the outside, again starting the distance measurement operation. Therefore, if the modulation control output of one of the two optical displacement measurement devices is directed to the modulation control input of the other, both the optical displacement measurement devices operate alternately, thus do not interfere with each other.

摘要： A fire alarm system, determining existence or nonexistence of a fire by using an ultrasound wave, comprises a sound wave generator and a sound wave detector to detect sound waves propagated through two propagation paths having different lengths each other. The system comprises a calculation means for calculating a pressure ratio between a first sound pressure, which is a sound pressure of a sound wave propagated through a first propagation path, and a second sound pressure, which is a sound pressure of a sound wave propagated through a second propagation path, and a smoke density estimator. The smoke density estimator calculates a change ratio between the pressure ratio calculated by the calculation means and a predetermined standard pressure ratio, and determines a smoke density from the change ratio based on a predetermined relational expression describing the relation between the change ratio and the smoke density, and determines existence of a fire when the smoke density exceeds a predetermined threshold.

摘要： A transport header analyzing unit (133) analyzes, on the basis of the TCP header of transport data transmitted from a transmitter terminal (100) to a receiver terminal (200), whether the transport data is an acknowledgement response in a TCP communication. If the transport data is not an acknowledgement response, a synchronization pre-processing unit (134) determines, on the basis of the TCP header of the transport data, whether synchronization information, which is required to operate in a power saving mode together with an access point (300), is added to the IP header of the transport data. A synchronization information processing unit (235) adds, to the IP header of the transport data indicating an acknowledgement response to received data that is received from the transmitter terminal (100), the synchronization information that is required to operate in the power saving mode together with the access point (300).

摘要： An infrared detection unit includes a base carrying an infrared sensor element, and a cap configured to be fitted on the base to surround the infrared sensor element. The cap has a top wall with a window in which a semiconductor lens is fitted to collect an infrared radiation onto the infrared sensor element. The semiconductor optical lens is formed from a semiconductor substrate to have a convex lens and a flange which surround said convex lens. An infrared barrier is formed on the semiconductor lens to block the infrared radiation from passing through the boundary between the circumference of the convex lens and the window. Accordingly, the infrared sensor element can receive only the infrared radiation originating from a detection area intended by the convex lens.

摘要： A semiconductor substrate is anodized to be shaped into an optical lens. Prior to being anodized, the substrate is finished with an anode pattern on its bottom surface so as to be consolidated into a unitary structure in which the anode pattern is precisely reproduced on the substrate. The anodization utilizes an electrolytic solution which etches out oxidized portion as soon as it is formed as a result of the anodization, to thereby develop a porous layer in a pattern in match with the anode pattern. The anode pattern brings about an in-plane distribution of varying electric field intensity by which the porous layer develops into a shape complementary to a desired lens profile. Upon completion of the anodization, the semiconductor substrate is shaped into the lens by etching out the porous layer and the anode pattern from the substrate.

摘要： This electrical power-receiving apparatus makes it possible to suppress a decline in power supply efficiency in a variety of different circumstances while avoiding an increase in circuit scale. This apparatus comprises an impedance control unit (307) for sequentially switching through any one of a plurality of charging devices in a charging device group (310), as candidate charging devices for a supply destination to which electrical power is to be supplied. The impedance control unit (307) also selects from the candidates a charging device to which electrical power is actually supplied, on the basis of the difference between the impedance of the charging device group (310) for each candidate and the impedance of an electrical power receiving antenna unit (301), and causes electrical power to be supplied to the selected charging device.
