|20140237271||CONTROLLING ENERGIZING RANGE OF MOBILE ELECTRONIC DEVICE - An energization range of a laptop PC is controlled for safety component replacement. An EC can communicate with a battery unit to control a FET of the battery unit. In a power-off state, a PWC receives electricity from the battery unit or an AC/DC adapter. In the power-off state, a system of the EC stops. When a housing cover of the laptop PC is opened, a cover switch turns ON. When a logic circuit detects the operation of the cover switch, the PWC controls a DC/DC converter group to activate the system. The EC receiving electricity turns the FET OFF. Then the PWC turns the FET OFF.||08-21-2014|
|20110246871||OPTIMIZED READING EXPERIENCE ON CLAMSHELL COMPUTER - The provision of an optimized arrangement for reading tasks at a clamshell or laptop computer, particularly to facilitate reading in portrait mode. Further contemplated herein are arrangements for readily switching between a reading (portrait) operating mode and a “normal” (landscape) mode. Such changes could be brought about via essentially any suitable arrangement, such as via an accelerometer which acts automatically, or a hotkey which is activated manually. Additionally contemplated herein is the use of mouse keys for alternative purposes specific to switching between the reading/portrait modes, such as utilizing left and right mouse buttons for page up and page down controls for reading (in portrait mode). A mouse pad (touchpad) can also be employed for alternative purposes in reading/portrait mode, such as the use of horizontal mouse pad scrolling for vertical document scrolling in reading/portrait mode.||10-06-2011|
|20100033938||METHOD AND APPARATUS FOR REDUCING CAPACITOR GENERATED NOISE ON A PRINTED CIRCUIT BOARD - Embodiments of the present invention provide an arrangement structure capable of reducing noise caused by a laminated ceramic capacitor mounted on a printed circuit board. A unit arrangement structure includes ceramic capacitors. Among the laminated ceramic capacitors, capacitors are arranged so that capacitor axes thereof extend along a first axis, while the other ceramic capacitors are arranged so that capacitor axes thereof extend along a second axis crossing the first axis. In accordance with such an arrangement structure, it is possible to effectively suppress noise even in the case of single-side mounting.||02-11-2010|
|20090089590||MERGING EXTERNAL NVRAM WITH FULL DISK ENCRYPTION - Methods and arrangements for managing a flash drive, hard disk, or connection between the two, in a manner to ensure that sensitive data is not decrypted at any time when it would be vulnerable. Accordingly, in a first implementation, the data may preferably be encrypted as it first goes into a flash drive and decrypted when it comes out of the flash drive. In another implementation, the flash drive may be logically bound to the hard disk, so that they would both use the same encryption key. In yet another implementation, if a hard disk is moved to another system, then the flash drive may also preferably be simultaneously moved.||04-02-2009|
