Abstract: In a range imaging camera, a first range image producing unit produces a first range image by calculating a distance to an object on the basis of the delay time or the received light amount of each pixel produced by a light receiving processing unit. A second range image producing unit produces a second range image by performing filtering for each pixel of the first range image using a group of neighboring pixels including its own pixel. In this case, a pixel group selection unit selects a group of pixels used in the filtering such that at least one of produced values including the delay time and the received light amount produced by the light receiving processing unit and the first range image produced by the first range image producing unit is equal to or larger than a noise component value.

Abstract: To simultaneously figure out information on a motion of the whole body of a subject and information on a small motion of a certain part of the subject by using range images obtained by imaging the subject, an image processing apparatus is configured to obtain first part information from a first range image obtained by imaging a first area of the subject. Second part information is obtained from a second range image of a second smaller area of the subject. A transformation function that performs coordinate transformation between a first coordinate system in the first part information and a second coordinate system in the second part information, and generates combined part information based on the transformation function, such that the combined part information is information representing the first part information and the second part information in the common coordinate system.

Abstract: A back-pressure valve comprises a case having first and second oil chambers through which oil passes. A piston is slidably accommodated within the case to partition the first oil chamber and the second oil chamber. A spring urges the piston in a sliding direction. A projecting member and a check valve allow the first oil chamber to communicate with the second oil chamber when the pressure of the oil in the first fluid chamber reaches a predetermined pressure. An area of the piston on which oil pressure is received in the first oil chamber is made lager than an area on which oil pressure is received in the second oil chamber. A part of the piston located at an end thereof opposite to the end thereof which faces the first oil chamber communicates with the outside of the case.

Abstract: A flight control surface control unit controls a swinging angle of a flight control surface of an aircraft by providing a swinging force to the flight control surface and swinging the flight control surface about a pivot. The flight control surface control unit comprises an actuator mounted on an airframe of the aircraft with a final output shaft of the actuator positioned coaxially with the pivot of the flight control surface. The final output shaft of the actuator and the flight control surface are connected to each other. The flight control surface is formed with a recess in the vicinity of the pivot thereof and the actuator is accommodated in the recess.

Abstract: Since the flight control surface 23 is adapted to be swung by the use of the oscillating rotary actuator 25 having a carrier 48 (final output shaft) being coaxial with the pivot of the flight control surface 23, the conversion mechanism (such as a fixed link) for converting a linear movement of the cylinder into a rotational movement, which was required in the related art may be eliminated, and thus the fairing for covering the conversion mechanism is not necessary. This allows reduction of air resistance of the aircraft during the flight, and thus improvement of the fuel consumption efficiency.
