  • Patent number: 10777183
    Abstract: A control apparatus, that can expand a range in which noise generated in an unmanned flying object is reduced, is provided. The control apparatus acquires position information of one or more unmanned flying objects and noise information concerning first noises generated by the one or more unmanned flying objects. The control apparatus also acquires output region information indicating an output region of sound output from a speaker. The control apparatus calculates, using the position information, the output region information, and the noise information, second noises that reach the output region. The second noises are caused by the first noises which are generated by the one or more unmanned flying objects. The control apparatus generates opposite phase signals for outputting opposite phase sounds with respect to the calculated second noises, and causes the speaker to output sound on a basis of the generated opposite phase signals.

  • Patent number: 9034502
    Abstract: A battery tray is fixed onto a front battery cross member lower and a rear battery cross member lower. The battery pack is mounted on the battery tray. The front battery cross member lower and the rear battery cross member lower come into contact with a deformable zone of the battery tray and the end face of each of battery cross member uppers at attachment portions. Space is created between the battery pack and the battery cross member uppers. The battery cross member uppers are welded so that a deformable zone having relatively low rigidity is formed. In this way, the front battery cross member lower and the rear battery cross member lower are fixed to a pair of side members through the battery cross member uppers.

  • Publication number: 20140329125
    Abstract: An undercover is provided which can have an electromagnetic shield effect in a vehicle. A battery unit is provided at a lower portion of a car body. The undercover is provided under the battery unit. The undercover functions to prevent an obstruction or a stone leaping during driving from directly hitting on a battery case. The undercover includes an undercover body and a cloth electromagnetic shield member formed of a conductive fabric. The conductive fabric is soft and flexible, and is molded along with the undercover body, with resin of the undercover body heated, so that they unite with each other. The resin is melted and stuck to the conductive fabric to obtain an anchor effect, as a result of which the conductive fabric is fixed to the resin of the undercover body.

  • Patent number: 4944021
    Abstract: An identification system for identifying authorized personnel compares a streaked pattern of a fingerprint of an individual with selected fingerprint patterns stored in memory of all authorized personnel in order to determine if the individual is included among the authorized personnel. The streaked pattern is compared with the fingerprint patterns stored in memory on the basis of characteristics between a reference point of a fingerprint and its relationship to other selected points of the fingerprint.

  • Patent number: 4905293
    Abstract: An image input device for optically sensing a fingerprint or like pattern to convert it to an electrical signal is disclosed. A guide is provided on a contact surface, or reflective surface, of a prism to orient the lengthwise direction of the pattern of an object parallel to a ridge, which is defined by an incidence surface and a wayout surface of the prism.

  • Patent number: 4872203
    Abstract: In an image input device for carrying out a preliminary operation prior to identification of an object placed on an input surface. The preliminary operation is for indicating a start time instant of the identification. Responsive to a succession of image signals extracted from the input surface, a timing controller produces partial image signals selected from the image signal succession in correspondence to positions which are unidimensionally or bidimensionally distributed on the input surface. Alternatively, the preliminary operation is for detecting whether the object is true or false. In this event, grey level comparison may be made as regards selected ones of the image signals that are in correspondence to preselected positions of the input surface. Variation of the image signals may be monitored at two different time instants.

  • Patent number: 4827527
    Abstract: In a pre-processing system (45) for pre-processing a succession of image signals which are extracted from an object on an input surface and which are representative of a ridge pattern of the object, a center position of the ridge pattern is determined with reference to the image signal succession and is compared with a center zone of the input surface so as to decide whether or not the center position is placed at the center zone. The center position can be decided by monitoring occurrence of runs along each scanning line and by detecting a maximum one of the numbers of runs. Alternatively, the center position may be decided by monitoring ridges extended in a preselected direction with respect to the scanning lines and by detecting a maximum one of the numbers of the ridges extended in the preselected direction. The pre-processing system may detect whether the object is true or false by monitoring the image signal succession.

  • Patent number: 4701959
    Abstract: A fingerprint input device for reading images of a fingerprint from a surface of a finger includes a base plate, an optical scanner, a rotary member, a first cleaning member, a switch, a detector and a control member. The optical member scans the finger-impressing surface to read the fingerprint. The rotary member has a first portion and a second, window portion. The first cleaning member is provided at the bottom of the first portion of the rotary member for wiping the finger-impressing surface by rotation thereof. The switch means is operated when the fingerprint input device is to be utilized, and the detector is operative for detecting release of the finger from the finger-impressing surface. The controller is responsive to outputs of the switch and the detector for controlling rotation of the rotary member to both expose the finger-impressing surface and to clean and cover same.
