摘要:
A mechanical transport device includes a system for transport; and a hard disk drive attached to the system. The hard disk drive comprises a magnetic recording disk to record data, a head to read or write the data to or from the disk, and a drop sensor designed to sense a shock condition. The system for transport may be a vehicle such as a car.

A method for is disclosed. A boot block that contains a first public key is activated and a system Basic Input/Output System (BIOS) that contains a second public key and a first digital signature is verified, the verifying being performed by confirming that the first and second public keys match. In response to a determination that the first and second public keys match, the BIOS is activated and a system image is loaded to a real device. The system image is verified by confirming that the first digital signature that is stored in the system BIOS matches a second digital signature that is stored in a mass storage device. In response to the first and second digital signatures matching, a virtual mass storage device is created. Control of the virtual mass storage device is transferred to a boot strap code in an operating system image and the operating system image is booted from the virtual mass storage device.

A magnetic disk device protection mechanism comprises a sensor that acquires information on changes in the environment of a magnetic disk device, a sensor driver, a shock manager that analyzes the information acquired by the sensor driver together with a history of the information to determine the status where the magnetic disk device is used to predict a shock, and an HDD filter driver that controls operations of the magnetic disk device including the escape of a magnetic head. The magnetic disk device can also comprise a diagnosis processing section that operates if a shock has occurred actually, to check whether or not the magnetic head could have completely escaped before the occurrence of this shock to carry out diagnosis as to whether or not a fault is occurring in the magnetic disk.

To enable a moving image to be clearly displayed on a hold-type of a display, such as a liquid crystal display, by setting a shutter function in an overlay processor, a computer having a display for displaying a moving image includes a memory with an on-screen area for storing display image information and an off-screen area for storing image information of the moving image. The on-screen area includes a memory area used as a display area of the moving image and which stores predetermined key color information. A data reading circuit reads the display image information from the on-screen area and the image information of the moving image from the off-screen area, and a shutter circuit outputs the image information of the moving image from the data reading circuit or predetermined color information by a predetermined frame. A key color detecting circuit determines whether the read display image information is the key color information or not, and a selector circuit outputs an image signal corresponding to the display image information to the display if the read display image information is not the key color information, and outputting a signal corresponding to an output of the shutter circuit to the display if the read display image information is the key color information.

A laptop PC is enabled to operate with small power consumption while maintaining a specific function. A laptop PC is provided with a HDD and can operate in a normal mode and a doze mode as a new operating mode. In the doze mode, the computer can operate with power consumption less than in the normal mode while executing a process to implement a specific function. In the doze mode a shift event is created, and a process existing at that time is force-suspended or an I/O processing completion notification is suspended to a process that makes an I/O request to the HDD. As a result, the laptop PC is enabled to operate with small power consumption by stopping the HDD while maintaining a specific function.

An apparatus, computer program product, and method are disclosed for access control to a mobile terminal. A use end event is generated indicating an end of use of a mobile terminal. Acceleration of the mobile terminal is binarized by the mobile terminal after the use end event is generated to one of a first value indicating a stationary state and a second value indicating a moving state. A use start event is generated indicating a start of use of the mobile terminal. A movement preparation period is measured from a time at which the use end event is generated to a time at which a transition from the first value to the second value occurs. Use authentication is requested in response to the use start event and in response to the movement preparation period exceeding a first threshold.

A camera system that transfers static image data while reducing power consumption is provided. A static image application issues a frame transfer command at a certain transfer period to a camera module. In each transfer period, the camera module wakes up from a suspend state and generates static image data. After the end of the transfer, the camera module transitions to the suspend state. The camera module is able to transition to the suspend state at each transfer period and thus is able to reduce power consumption.

A method and system are provided for thermal management of a portable computing apparatus. Accelerometers are provided to detect changes in attitude, and temperature sensors are provided to detect changes in temperature. A fan is used to cool the internal temperature of the electronic components of the computer. In response to lift of the computer from a stationary surface, the computer may transition to an alternative state of operation. The transition may include the change of the speed of the fan and/or adjustment of the processor clock.

An information processor for information registration, capturing means captures a graphics processing command, and database registering means registers, as information about completed work in the database, information about a series of graphics processing commands concerning completed works out of the captured graphics processing commands. In an information processor for information retrieval, proceeding work detecting means detects a work in progress as a proceeding work based on the captured graphics processing command, and information acquiring means searches a database for the information about the work in progress which has been done before based on the graphics processing command concerning the proceeding work and acquires the information about the work in progress which has been done before.
