  • Publication number: 20240111178
    Abstract: A contact lens comprises an optical zone and a peripheral zone. The optical zone is used for vision correction. The peripheral zone surrounds the optical zone. The optical zone and the peripheral zone jointly define a geometric center and a horizontal axis passing through the geometric center. Two stabilization zones symmetrically arranged relative to the geometric center are formed in the peripheral zone. These stabilization zones gradually thicken relative to a base curved surface of the peripheral zone.

  • Publication number: 20100133398
    Abstract: A linkage and a supporter are attached to a back of the housing via a magnetic element of an electronic device with a magnetic supporter. The supporter is drawn to a supporting position via the linkage to support the electronic device body and provide various angles for the user to easily operate the electronic device in several modes. Moreover, since the linkage and the supporter are attached via the magnetic element, when the electronic device body is overloaded, for example, a user applies overlarge force to operate a touch panel, the magnetic element is detached from the electronic device body to prevent the linkage and the supporter from being damaged or permanently destroyed.

  • Publication number: 20080112114
    Abstract: A portable electronic device includes a casing, an active function area, a passive function area and at least a heat pipe is provided. The active function area is provided inside the casing. The active function area has at least one processor, at least one input device and at least one output device. The passive function area is independent of the active function area. The processor and the passive function area are connected by the heat pipe, by which the heat generated by the processor is conducted. The heat generated by the active function area is conducted by the heat pipe to the independent passive function area effectively. Therefore, the portable electronic device has a better heat dissipating effect.

  • Patent number: 7187537
    Abstract: A portable computer with a position-adjustable keyboard is used to provide a comfortable typing environment. More space is laid out for accommodating the keyboard, and the act of opening the panel is used to move the keyboard position. An adjustment mechanism is installed around a rotation shaft of the portable computer. A first gear is mounted on and rotated simultaneously with the rotation shaft. A cylinder is positioned adjacent to the rotation shaft, and a second gear is mounted thereon. A wire, rolled around the cylinder, interconnects the position-adjustable keyboard and the cylinder. When the panel is unfolded, the first gear rotates with the panel, and drives the second gear. The wire, pulled by the cylinder, moves the position-adjustable keyboard to the desired position for comfortable typing.

  • Patent number: 7076837
    Abstract: A hinge device for pivotally coupling a display to a base includes a seat for being secured with the base, a rotor, a pair of hinges, and at least one roller located on the rotor. The seat defines a hole, and a railway defined in an inner wall of the seat. The rotor includes a shaft pivotally received in the hole, and a pair of beams. Each hinge includes a first rotating member for being attached to the respective beam, and a second rotating member pivotally engaged with the first rotating member for being attached to the display. The roller is movably received in the railway. The railway defines at least two points located in two different planes perpendicular to an axial direction of the shaft. When the shaft of the rotor rotates, the roller moves along the railway to cause the rotor to move in said axial direction.

  • Publication number: 20040200036
    Abstract: A hinge device for pivotally coupling a display (70) to a base (80) of an electronic device. The hinge device includes a seat (30) securing in the base and a rotor (40) attached to the display. The seat defines a center through hole (35) therein and a railway (36) in an inner wall of the seat. The rotor includes a shaft (42) pivotally received in the center through hole of the seat and a pair of opposite beams (43) connecting to the display. At least one socket (45) is defined in an outer wall of the shaft. A roller (50) is tightly held between the socket of the rotor and the railway of the seat. The roller moves along the railway when the rotor rotates in the seat. The display swivels relative to the base and alters the vertical distance from the base.

  • Patent number: 5849640
    Abstract: A method is disclosed for improved planarization and deposition of intermetal dielectric layers in semiconductor substrates. More specifically, the method involves the performance of specific process steps in-situ. That is, unlike in prior art, starting with cured spin-on-glass (SOG), the steps of SOG etchback and deposition of the intermetal dielectric PECVD, all take place sequentially in the same chamber and without a vacuum break. If not in the same chamber, then in the same load lock system. In this manner, it is shown that no longer does the SOG layer delaminate from the oxide layer. Furthermore, because the system is not exposed to moisture due to the absence of vacuum break, there is no adverse reaction when metal is deposited into the via holes.
