Patent number: 8539176Abstract: A data storage device accepts queued read and write commands that have deadlines. The queued read and write commands are requests to access the data storage device. The deadlines of the queued read and write commands can be advisory deadlines or mandatory deadlines.Type: GrantFiled: July 8, 2008Date of Patent: September 17, 2013Assignee: HGST Netherlands B.V.Inventors: Donald Joseph Molaro, Frank Rui-Feng Chu, Jorge Campello de Souza, Atsushi Kanamaru, Tadahisa Kawa, Damien C.

Patent number: 8130199Abstract: A keyboard type input device used in conjunction with a wristwatch or a portable telephone has multiple key positions provided as character entry keys. Each key corresponds to one key in the selected row of the conventional QWERTY keyboard. A second set of control buttons provide for the selection of which row of a conventional QWERTY keyboard are represented by the character keys in addition to other functions such as case shift, and alpha-numerical control functions. A selected row is shown on a display, as visual feedback. Alternatively the keys are implemented as LCDs with pressure sensors and the characters of the selected row are displayed directly on the corresponding key positions. The keyboard finds particular use in portable devices as it demands less space than traditional keyboards.Type: GrantFiled: August 6, 2008Date of Patent: March 6, 2012Assignee: International Business Machines CorporationInventors: Frank Rui-Feng Chu, Noboru Kamijo, Denny Duan-Lee Tang

Patent number: 6725385Abstract: A device connected to an interface has operational logic and power control logic. The device further has multiple power modes, including a first mode and a second, lower power mode. In the first mode, the operational logic is coupled to the interface, and is able to communicate over the interface. In the second mode, the power control logic is coupled to the interface, and the operational logic is decoupled, and substantially powered down. This provides a low interface power mode. In this mode, the power control logic monitors the interface for command activity. The power control logic returns the device to the first mode when the device must be in the first mode to process or reply to the command. The power control logic thus provides for the restoration of function from a low interface power mode without the need for a special “wake-up” command, thereby making the low interface power mode transparent to the host.Type: GrantFiled: September 11, 2000Date of Patent: April 20, 2004Assignee: International Business Machines CorporationInventors: Frank Rui-Feng Chu, Steven R.
