Abstract: A radar signal imaging device 30 includes: a transmission unit 31 which transmits a radar signal toward an object to be imaged that is a non-rigid body; a position estimation unit 32 which estimates the position of the object; an oscillation degree estimation unit 33 which estimates an oscillation degree which is a degree of change within a predetermined period in the relative positions of feature points constituting the object; and a synthetic aperture processing unit 34 which performs synthetic aperture processing on the radar signal reflected by the object on the basis of the estimated position of the object and the estimated oscillation degree.

Abstract: In an apparatus having a video display and display-synchronizing motion mechanism, various images can be easily selected and displayed, and a seat or the like is moved in synchronism with motions in the images, so that a person can enjoy the images as if real. An information select unit specifies a desired one of a plurality of video/motion information pieces recorded on a storage medium, and an information read unit reads the specified video/movement information. Images formed by video information contained in the readout video/motion information are displayed on a display device, and the seat or the like is moved in synchronism with the images on the basis of motion information contained therein. A monitor unit monitors the readout video/motion information, and stops a read operation of the information read unit when the apparatus malfunctions.

Abstract: A package for batteries which comprises a header board and a heat-shrunk thermoplastic film holding the batteries relative to the header board. The header board has a vertical wall and a skirt integrally extending downwardly from the lower end of the vertical wall and covering a portion of the battery. The thermoplastic film covers the skirt and the batteries.
