  • Publication number: 20080190674
    Abstract: The operation of a discharging apparatus for correcting variations in voltage and remaining capacity among battery blocks forming a battery pack is performed more reliably. When power supply from a battery pack to a motor/generator is not being performed and when a variation amount of remaining capacity among the battery blocks forming the battery pack is larger than a predetermined value, a discharge request section issues a command to start power supply from a battery block to a discharge control unit corresponding to at least a battery block having the largest remaining capacity among the battery blocks. The discharge control unit receives the start command for power supply from the battery block and issues a command to a discharging section to discharge the battery block in response to start of the power supply from the battery block.

  • Patent number: 7404459
    Abstract: A positive side main contactor serving as a contact switching device on the positive side, which is connected between a positive electrode terminal of a battery pack and a high potential input terminal of an inverter, and a negative side main contactor serving as a contact switching device on the negative side, which is connected between a negative electrode terminal of the battery pack and a low potential input terminal of the inverter, are arranged so that moving contacts of these are moved forward and backward in directions that are different from each other, e.g. by 90 degrees. Thus, a situation in which the two main contactors are simultaneously turned ON upon external impact can be avoided, and consequently, it is possible to achieve the same impact resistance as was previously possible with a smaller spring force than was previously required.

  • Patent number: 7324669
    Abstract: Disclosed is an image processing apparatus in which the cheek of a person captured in an image of a photo may be corrected to a finish with the cheek looking slimmer than in a two-dimensional photo. A face correction unit (400) calculates, in a calculation unit (411), a face length L1 and a cheek width L2 of a face of a person as an object and L3 corrected from the face length L1. A face classifying unit (412) compares L2 and L3 to each other to classify the face shape into a ‘round shape’, ‘a long shape’ and a ‘square shape’. Depending on the results of classification, the image trimming is carried out by a first contour correction unit (413), a second contour correction unit (414), and a third contour correction unit (415) so that the cheek will look slim.

  • Publication number: 20070297649
    Abstract: Scenes can be discriminated automatically and optimum prints corresponding to the scenes can be obtained. A face of person is detected from an inputted image and it is determined whether or not a person is on the scene of the inputted image. If it is determined that a person is not on the scene of the inputted image, then it is determined that the inputted image is a landscape image. If it is determined that a person is on the scene of the inputted image, then the face area is calculated and the number of people is counted. If the face area is more than a predetermined ratio of the screen and the number of people is not less than a predetermined number of people, then it is determined that the inputted image is a snapshot of people image. If the face area is more than the predetermined ratio of the screen and the number of people is less than the predetermined number of people, then it is determined that the inputted image is a portrait image.
