| 20130120750 | OPTICAL PHASE DEVICE, METHOD AND SYSTEM - The invention provides an optical phase device with its application method and system. The optical phase device consists of a transparent dielectric substrate, a multilayer stack of dielectrics and a buffer layer. The refractive index of the transparent dielectric substrate, the multilayer stack of dielectrics and the buffer layer are all larger than that of the external medium. For the wavelength of the incident beam, the optical phase device has a phase variation in the angular range [α, β] and the critical angle for total reflection on the interface between the buffer layer and the external medium adjacent to the buffer layer is γ, γ>β. Our invention of the optical device has both low loss and large phase variation, which leads to a large Goos-Hanchen shift. As a dispersion compensation component, it can produce bigger and tunable dispersion, and different dispersion compensations can be got by adjusting the operating angle or parameters in the structure. | 05-16-2013 |

| 20120191853 | COMPUTER - A computer includes an enclosure, a network card connected to an external network, a time limit control device, a power module, and a switch. The time limit control device is used to set a connection time of the computer with the external network, and control a network switch module to enable the network card to connect the computer to the external network according the set connection time. The time limit control device is used to count down the connection time, and control a display module to display a remaining connection time. When a countdown of the connection time is zero, the time limit control device controls the network switch module to disable the network card and thereby disconnecting the computer from the external network. | 07-26-2012 |
| 20120272097 | TESTING DEVICE FOR REDUNDANT ARRAY OF INDEPENDENT DISKS - An exemplary testing device includes a RAID unit including under test disk drives, a replacing unit including a reserve disk drive, a switching unit, a state recognition unit and a control unit. The switching unit includes buttons corresponding to the under test disk drives, respectively. Each of the buttons is switched between a first position in which a corresponding under test disk drive is in connection with the RAID unit and a second position in which the corresponding under test disk drive is disconnected from the RAID unit. The state recognition unit outputs status signals corresponding to the under test disk drives, respectively. The control unit receives the status signals from the state recognition unit and controls the reserve disk drive to successfully begin to work in replacement of the disconnected under test disk drive for rebuilding the RAID unit. The display unit displays a testing result thereon. | 10-25-2012 |
| 20120293014 | POWER SUPPLY - A power supply includes an alternating current (AC)/direct current (DC) converter, a control unit, and a selection switch. The AC/DC converter is connected to an AC power source to convert an AC voltage into a DC voltage. The control unit includes a controller and a switch. The selection switch is connected to the controller, and connected between the AC converter and the power module of a motherboard to connect the AC converter to either the power module or the controller. When the AC/DC converter is connected to the controller, the controller receives the DC voltage to be started, the controller turns on the switch for a predetermined connection time to make the DC voltage be input to the power module, and then turns off the switch for a predetermined disconnection time to make the DC voltage fail to be input to the power module. | 11-22-2012 |
