  • Publication number: 20020044216
    Abstract: An apparatus that adjusts an angle of image device for information processing equipment such as a portable computer, a computer for a Liquid Crystal Display (LCD) monitor, and a Personal Digital Assistance (PDA) in which a display device is rotated from a main body or supporting member adjusts according to rotation of the display device to maintain a desired angle of the image device. The information processing equipment can include a main body with a plurality of key buttons and a display body including a display unit and rotationally coupled to one side of the main body. An image device unit is installed on one side of the display body for holding the image device. A connecting link rotates the image device unit in accordance with the rotation angle of the display body against the main body. Therefore, the angle of image device such as a camera can be automatically controlled according to the movement of the display body.

  • Patent number: 5720296
    Abstract: An apparatus for analyzing body composition based on bioelectrical impedance analysis, and a method therefor are disclosed. The method for analyzing body composition includes the step of providing eight electrodes for being contacted to a right palm, a right thumb, a left palm, a left thumb, a right front sole, a right rear sole, a left front sole and a left rear sole. Then a switch is selected by a command of a micro-processor so as to form a current path. Then a current is made to flow through said selected electrodes and through a human body to an impedance measuring instrument. Then a switch is selected by a command of said micro-processor so as to form voltage electrodes. Then impedances for respective body portions are measured by means of the impedance measuring instrument. Then impedances of two body portions are decided based on the current and voltage of the impedance measuring instrument. Then the body composition is analyzed based on the measured impedance.
