摘要:
There is provided a road configuration estimation apparatus that precludes influences of erroneous detection of an object and erroneous still determination and estimates a road configuration.A radar (peripheral object observation device) 110 repeatedly observes a relative position of an object relative to the moving object, which is located in the vicinity of a moving object. A stationary object identification unit (stationary object determination unit) 130 determines whether or not the object the relative positions of which have been observed by the radar 110 is still. A road approximate curve temporary computation unit (object correlation unit) 140 determines a plurality of the relative positions of an identical object observed by the radar 110 from among the relative positions observed by the radar 110. A road approximate curve main computation unit (approximate curve computation unit) 160 computes an approximate curve that approximates the configuration of a road on which the moving object is located, based on a result of the determination by the stationary object identification unit 130 and a result of the determination by the road approximate curve computation unit 140.

A radar device including an up-chirp tracking filter that performs a tracking process using a beat frequency at the time of an up-chirp to acquire a beat frequency, a down-chirp tracking filter that performs a tracking process using a beat frequency at the time of a down-chirp to acquire a beat frequency, target detectors that calculate distance and speed estimated values of the target for the chirps from beat frequency time series data about the chirps; an identical target determinator that determines whether or not the target detected for each of the chirps is an identical target using the distance and speed estimated values, and a distance and speed calculator that calculates a distance and a speed of the target using the beat frequency of the target which is determined to be an identical target.

摘要:
An X-ray analysis apparatus includes: an X-ray radiation unit that irradiates a sample with X-ray; an X-ray detection unit that detects X-ray emission from the sample; a unit that allows the X-ray detection unit to perform scanning operation for changing the angle of the X-ray detection unit with respect to the sample; and an image controller that displays information related to X-ray intensity detected by the X-ray detection unit and information related to a scanning angle of the X-ray detection unit as a 3D image. The image controller displays the 3D image simultaneously with the scanning operation of the X-ray detection unit. Further, simultaneously with the scanning operation of the X-ray detection unit, two or all of 1D, 2D, and 3D images are displayed in one screen. A measurement result starts being displayed as a 3D image before information related to all measurement results has been obtained.
摘要:
An audio recording device is provided with a first casing, which includes a sound collection means, a second casing, which includes a terminal for connection to an external device. One end portion of the second casing is rotatably joined to a lower end portion of the first casing, such that the second casing can be folded and stored on a rear side of the first casing; the sound collection means is provided at an upper portion of the first casing; and the connection terminal is protrudingly provided on another end portion of the second casing. Furthermore, a recessed portion, into which the connection terminal is fitted, may be formed at a raised portion on the rear side of the first casing, and a front end portion of the connection terminal may be covered by a wall of the recessed portion when the second casing is in a folded and stored state.

摘要:
An audio recorder having a plurality of microphones including at least a first microphone and a second microphone provided in a first housing and a second housing, respectively, at least one of the first housing and the second housing being rotatably supported, and having an audio recording function in a set prescribed audio recording mode, in which the first housing and the second housing are arranged vertically one above the other, and the audio recorder has means for setting a prescribed audio recording mode in accordance with a relative position of the first microphone and the second microphone. According to this audio recorder, the prescribed audio recording mode is set in accordance with the relative position of the first housing and the second housing. Thus, a desired audio recording mode can be set more intuitively by a user.
