Abstract: The present invention provides to a battery module which is excellent in cooling performance of a battery and is improved in assembling easiness at low cast. A battery module 3 accommodates assembled battery blocks 20 arranged in series in an exterior case formed in an approximately hexahedral shape in parallel, each assembled battery block 20 including six assembled battery units electrically connected in series and each assembled battery unit including four cylindrical unit cells arrange such that their polarities are alternating. An exterior case is formed by connecting a lower lid 22 having a front face, a bottom face, and a back face and an upper lid 41 having a left side face, an upper face, and a right side face. End portions of the left side face, the upper face, and the right side face of the upper lid are drawn at the sides of the front face and the back face of the lower lid.

Abstract: The present invention provides an assembled battery with reduced weight and high reliability that can achieve improvement of assembling easiness at low cost. An assembled battery is provided with a frame holding a plurality of unit cells 14 having positive polarity at one end and negative polarity at the other end. The frame is composed of two outer frames 2 having the same shape and an inner frame 3. The unit cells 14 constituting an assembled battery 1 are disposed on both sides of the inner frame 3, and one outer frame 2 and the other outer frame 2 are disposed such that the unit cells are sandwiched between the former outer frame 2 and the inner frame 3 and between the latter outer frame 2 and the inner frame 3. The two outer frames 2 are joined to the inner frame 3 through side face coupling portions 23 and vertical coupling portions 24.

Abstract: The present invention provides a secondary battery module which is excellent in vibration resistance. A battery module 20 has assembled battery blocks 11 each constituted by screw-fixing the assembled batteries 2 to the block bases 3, 4 supporting a lower portion thereof and the two block reinforcing plates 5 supporting an upper portion thereof, the six assembled batteries 2 are sandwiched by and fixed firmly to the block bases 3, 4 and the block reinforcing plates 5. The assembled batteries 2 do not move freely even if vibration is added to the battery module 20. Because the elastic sheet 9 is laid between the block bases 3, 4 and the assembled batteries 2, since a space derived due to variance in size accuracy of frames 12 which hold and fix the unit cells 11 and derived due to variance in size accuracy of the block bases 3, 4 can be removed, and vibration resistance can be enhanced.

Abstract: A video signal produced through a shooting operation of a camera is sent to a motion detecting unit which detects a motion included in the video signal to set an area of the motion as a space motion area and inputs information of the area to a distance determination circuit which calculates distance between the motion area and the camera by use of a parallax signal produced from stereo cameras disposed in the camera to send information of the space motion area and the distance to a mask determination circuit. The mask determination circuit conducts a comparison between the space motion area information and the space mask area information and between the distance information of the motion area and that of the space mask area, and resultantly compares three-dimensional positions between the detected motion and the mask to determine a position relationship therebetween.
