Abstract:
A microphone array system includes a camera that images a picture for a target place, a microphone array that picks up sound using a plurality of microphones, a sound source analyzer that calculates a sound source position based on picked up sound data, an image displaying processor that displays image data, which includes sound source position display indicative of an imaged target place picture and the sound source position on the display, a user-input apparatus that receives an instruction of a specified spot in the target place picture displayed on the display, a directivity calculator that forms sound directivity in a direction which faces the specified spot from the microphone array based on the picked up sound data, and generates the sound data acquired by emphasizing sound in a direction having the directivity, and a sound outputter that outputs the sound data to the speaker and reproduces the sound data.
Abstract:
Provided is a printed circuit board (1) on which the power supply circuit is mounted and a casing (2) which is shaped like a flat as a whole and in which the printed circuit board (1) is housed. An input terminal (11) of the power supply circuit is connected to an input socket (3) fixed to one end part, in a direction perpendicular to a thickness direction of the printed circuit board (1), of the casing. An output terminal (12) of the power supply circuit is connected to an output socket (4) protrudes from one side, in the thickness direction of the printed circuit board (1), of the casing (2). The casing (2) has a bulge part (21) which protruded to an opposite side to the protruding side of the output socket (5) and to which the input socket (3) is fixed.
Abstract:
A recorder receives designation of a video which is desired to be reproduced from a user. If designation of one or more designated locations where sound is emphasized on a screen of a display which displays the video is received by the recorder from the user via an operation unit during reproduction or temporary stopping of the video, a signal processing unit performs an emphasis process on audio data, that is, the signal processing unit emphasizes audio data in directions directed toward positions corresponding to the designated locations from a microphone array by using audio data recorded in the recorder. A reproducing device reproduces the emphasis-processed audio data and video data in synchronization with each other.
Abstract:
In an object, for example, a pilotless flying object detection system, an omnidirectional camera as a first camera images a monitoring area. A microphone array acquires audio of the monitoring area. A monitoring apparatus uses the audio data acquired by the microphone array to detect a pilotless flying object which appears in the monitoring area. A signal processor in the monitoring apparatus superimposes a discrimination mark, obtained by converting the pilotless flying object into visual information, on image data of the monitoring area when displaying the image data of the monitoring area captured by the omnidirectional camera on a monitor.
Abstract:
There is provided a collation device capable of capturing a face image suitable for collation by an imaging device while making a display suitable for collation by a display to a person in the front side of a half mirror. By disposing a plurality of displays with predetermined gap in the back side of the half mirror and disposing camera lenses and in this gap, it is possible to make the line of sight for viewing the display and the line of sight for imaging by the cameras be almost the same. As a result, it is possible to capture a face image suitable for collation by an imaging device while making a display suitable for collation by a display to a person in the front side of the half mirror.
Abstract:
A gate device disposed between a first space where a person waiting for passing through exists and a second space where a person already passed through exists, the device including: a gate main body disposed along a path through which the person existing in the first space passes when the person moves to the second space; a shutter for blocking or opening the path; and a structure disposed on an upper surface of the gate main body and having a first sensing device for sensing a person passing through the path, and a second sensing device for sensing a person passing through a side opposite to the path across the gate main body.
Abstract:
In an unmanned aerial vehicle detection system, an omnidirectional camera images a monitoring area. A microphone array picks up a sound in the monitoring area. A monitoring device detects an unmanned aerial vehicle appearing in the monitoring area using the sound data picked up by the microphone array. When displaying image data of the monitoring area captured by the omnidirectional camera on a monitor, a signal processor in the monitoring device superimposes an identification mark obtained by converting the unmanned aerial vehicle into visual information on the image data of the monitoring area.
Abstract:
An aircraft includes: a plurality of rotor units each of which includes a propeller, and a motor which drives the propeller; and a balloon to which the plurality of rotor units are connected and in which a gas less dense than air is contained. At least one rotor unit among the plurality of rotor units generates downward thrust.
Abstract:
An aircraft includes: a plurality of rotor units each including a propeller and a motor that drives the propeller; a balloon that laterally covers the plurality of rotor units, across a height of the plurality of rotor units in an up-and-down direction; and a drive unit configured to change the external shape of the balloon at a predetermined timing.
Abstract:
An aircraft includes: a plurality of rotor units each including propeller and motor that drives propeller; a shock absorber covering an entire vertical length of a lateral side of the plurality of rotor units; and a plurality of rudders each being disposed downstream of a corresponding one of the plurality of rotor units and rotating about axis of rotation that extends in a direction intersecting a flow direction of air current generated by the corresponding one of the plurality of rotor units.
