  • Publication number: 20110314203
    Abstract: Resource adjustment methods and systems for virtual machines (VMs) for use in at least one physical device are provided. First, a first VM having a first resource set and a second VM having a second resource set are respectively enabled to enter a suspended state. A first user space address and a second user space address are respectively obtained from a first VM memory page table corresponding to the first VM and a second VM page table corresponding to the second VM, and a first physical memory address corresponding to the first user space address in the physical device and a second physical memory address corresponding to the second user space address in the physical device are obtained from a Hypervisor. The first user space address is mapped to the second physical memory address by the Hypervisor. Then, the first VM is enabled to enter an execution state, and the second VM is stopped.

  • Publication number: 20110298348
    Abstract: A linkage mechanism is configured between two relatively slidable first housing and second housing of a handheld device. The linkage mechanism can be actuated by a first actuator of the first housing when the second housing slides out at an opening status relative to the first housing. The linkage mechanism is actuated to rotate and then to drive a second actuator to slide on the second housing and the second actuator forces a supporter, which pivots to the second housing, to open at a predetermined angle relative to the second housing. The handheld device is made steady on a plane through the support provided by the opened supporter. When the handheld device slides in at a closing status, a restoring spring configured between the supporter and the second housing automatically folds the supporter.

  • Patent number: 7485996
    Abstract: A position retention device includes a pivot member having a mounting axle, a cylindrical seat, a cylindrical housing and an annular member. A cylindrical seat is mounted co-axially on the mounting axle of the pivot member, and has pluralities of circumferentially formed and alternately disposed north and south pole sectors. A cylindrical housing is mounted co-axially and rotatably on the mounting axle of the pivot member. An annular member is disposed within the annular receiving chamber in the cylindrical housing for simultaneous rotation with the cylindrical housing. The annular member has pluralities of circumferentially formed and alternately disposed north and south pole sectors. Position of the cylindrical housing is retained stationarily with respect to the cylindrical seat by virtue of attraction between adjacent two of the north or south pole sectors of the cylindrical seat and the annular member.

  • Patent number: 7267566
    Abstract: A hinge assembly includes an inner ring and an outer ring. The outer ring has an outer ring slot penetrating the sidewall of the outer ring and connecting both ends of the outer ring. The inner ring has an inner ring slot penetrating the sidewall of the inner ring and connecting both ends of the inner ring. The inner ring is coaxially connected to the outer ring. When the inner ring slot and the outer ring slot are aligned, an electrical connecting device can pass through the inner ring slot and outer ring slot to stay in the hinge assembly.

  • Patent number: 7261579
    Abstract: A wire-to-board connector for coupling electrically a circuit board to a transmission wire unit, includes a plug receptacle, a plurality of signal contacts and a mating header. The plug receptacle is mounted on the circuit board. The mating header includes an insert body that is disposed at one end of the transmission wire unit and that has a plurality of resilient metal elements. When the insert body is plugged into the plug receptacle, the resilient metal elements respectively contact with the signal contacts of the plug receptacle, thereby establishing electrical communication with the circuit board and the transmission wire unit.

  • Publication number: 20070091582
    Abstract: A mobile phone includes a main body, a first magnetic device, a slide cover and a second magnetic device. The first magnetic device is disposed on the main body. The slide cover is slidably connected to the main body and can slide relative to the main body. The second magnetic device is disposed on the slide cover. When the slide cover moves to a distance relative to the main body, the first magnetic device attracts the second magnetic device so that the slide cover slides to a first positioning point.

  • Publication number: 20060261605
    Abstract: A device having a magnetically rotary cover mechanism is disclosed. Coupled magnets are pivotally mounted on one side of a cover cap of the device, and an attractive or repulsive force between the coupled magnets controls the cover cap to close an opening. The present invention uses the coupled magnets to replace the conventional elastic members for controlling the cover cap to close the opening, thereby simplifying and saving the process and time for assembling the device.
