| 20110063750 | SYSTEM AND METHOD TO CONTROL SPIN-UP OF STORAGE DEVICE - A storage device spin-up control system includes a storage device to store data, a host to selectively control a spin-up mode of the storage device, and an interface to link the storage device and the host. The host controls the spin-up mode of the storage device based on a level of a signal output from a power connector of the interface. Thus, spin-up failure of the storage device due to insufficient power supply from the host may be prevented. | 03-17-2011 |
| 20120072755 | METHOD OF CONTROLLING OPERATION MODE OF STORAGE DEVICE, AND STORAGE DEVICE IMPLEMENTING THE STORAGE - A method and apparatus control an operation mode of a storage device, including determining, by the storage device, an external power connection state of a host device connected to the storage device; and determining the operation mode of the storage device according to the determined external power connection state. The operation mode is determined to be a first mode when external power is connected to the host device and the operation mode is determined to be a second mode when the external power is not connected to the host device, where power consumption in the second mode being smaller than power consumption in the first mode. | 03-22-2012 |

| 20090149426 | PROCESS FOR SYNTHESIZING SILVER-SILICA PARTICLES AND APPLICATIONS - Size-controlled immobilization of metal nano-clusters onto particles or nanoparticles is achieved using a polyol process. Polyol processing makes it possible to use thiol groups as a chemical protocol to functionalize the surface of particles, such as silica and polystyrene nanoparticles. Metal nano-clusters, such as silver, gold, platinum and palladium, nucleate and grow on the surface of the particles. The metal nano-clusters may be synthesized in a one-pot process from metal salts, nitrates, nitrites, sulfates, sulfites and the like. Any source of metal ions compatible with the polyol suspension and selected particles may be used. The size of immobilized metal nano-clusters may be controlled by additions of a poly(vinylpyrrolidone) or other polymer capable of regulating the metal ion reduction and nucleation process and by controlling concentration of metal ions, the nucleation and/or growth temperatures, and processing time. | 06-11-2009 |
