摘要： In an apparatus using an intensity-modulated light for detection of spatial information based upon light intensity of light reflected from a target space, a timing synchronization circuit is provided to synchronize a phase of the intensity-modulated light from a light-emitting element with a timing of operating a light-receiving element receiving the intensity-modulated light. The light-receiving element is caused to operate for enabling the detection of intensity of the received light for each of a plurality of phase regions within one cycle of the intensity-modulated light. The timing synchronization circuit functions to compare a cyclic variation determining the operation of the light-receiving element with a cyclic variation associated with an output from a light-emitting element driving circuit in order to keep a constant phase difference between these two cyclic variations.

摘要： A variable-length key cryptosystem is provided, in which the amount of parameters for generating a key to be shared is small, security is high, and calculation cost is small.The length of a plain text inputted from a data input part 10 is detected by a data string length detection processing part 20. A variable-length key generation processing part 30 generates an encryption key with a required arbitrary length, using an initial character string and a conversion rule, based on the length of a plain text. A conversion character string generation processing part 32 generates a converted character string from an initial character string by applying a conversion rule of increasing the length of a character string. Conversion is conducted until the length of a plain text is reached. An encryption key is not used twice. Therefore, an unused conversion character string is searched for, and a stream code processing part 40 generates an encrypted text by using a generated encrypted string. A receiver system 200 generates a converted character string from an initial character string by the same conversion, based on the length of an encrypted text, thereby obtaining the same encryption key.

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： An optical measurement system for determination of a profile or thickness of an object includes first and second optical heads directing first and second light beams, respectively on first and second points on the surface of the object. Photo-sensors are included respectively in the first and second optical heads for receiving reflected lights from said first and second points and providing first and second outputs which varies in proportion to perpendicular distances from a reference plane to said first and second points on the object's surface. The first and second outputs are transmitted selectively to a single processing circuit through a switch. The processing circuit operates to process the first and second outputs in sequence to measure by triangulation the perpendicular distance of the first and second points from the reference plane and to analyze a surface or thickness of the object based upon thus measured perpendicular distances. With the use of the single processing circuit, the first and second outputs can be processed in the identical conditions to enable reliable determination of the perpendicular distances of the first and second points from the reference plane and therefore accurate analysis of the surface profile or the thickness of the object.

The radar device comprises: a transmission unit that transmits a transmission wave, based on a transmission signal, toward the target; a receiving unit that receives a reflected wave generated by the transmission wave being reflected by the target, and thereby generates a reception signal; and a target detection unit that acquires information on the target on the basis of the transmission signal and the reception signal. The target detection unit calculates the relative speeds of a plurality of detection points within the same target, and determines the type of the target on the basis of the spread of the relative speeds.
