摘要:
A device, method, and computer program product for a self-calibrating input device are provided. The input device includes a designated value change unit operable to change a designated value using a variation amount associated with the designated value, the designated value being changed using a predetermined first variation amount when a first designated value change directive is received from an operator, and a variation amount change unit operable to alter the variation amount associated with the designated value from the predetermined first variation amount to a smaller second variation amount when a second designated value change directive that is opposite the first designated value change directive is received from the operator within a predetermined variation amount change period.

A display device which displays a plurality of objects on a screen has a group configuration storage section for storing association information indicating the association between each of the plurality of objects and one of a plurality of groups, a group priority level storage section for storing group display priority levels which are priority levels for displaying each of the objects associated with one of the groups at the front of the objects associated with the other groups, an object priority level storage section for storing object display priority levels which are priority levels for displaying one of the objects associated with one of the groups at the front of the others, an object priority level changing section for changing the object display priority level while the association information is maintained, and a display section for displaying the plurality of objects according to the group display priority levels and the object display priority levels.
摘要:
An information processing apparatus driven by an AC power supply or a rechargeable battery has a charge directing unit which initiates charging of the battery from the AC power supply, provided that the remaining amount of power of the battery is lower than a predetermined charge-start-criteria level and that the information processing apparatus is driven by the AC power supply. Also included is a drive history storage which stores a drive history including information indicating which of the AC power supply and the battery was driving the information processing apparatus in each time period in the past. A recharge-start-criteria-level-setting unit sets the charge-start-criteria level on the basis of the drive history.
摘要:
A semiconductor memory device characterized by the fact that the disturb test time of the semiconductor memory device can be shortened, and the power consumption can be cut.In the disturb test for the semiconductor memory device in this invention, multiple word lines are selected at the same time with a prescribed interval corresponding to the element isolation layout. As the word lines are selected corresponding to the element isolating layout, the interference caused by the element isolation state can be excluded. Since multiple word lines are selected at the same time, the time of operation can be shortened. Since the word lines are maintained in the selected state while the sense amplifiers are not reset, there is no increase in the power consumption although multiple word lines are selected at the same time.

摘要:
Data selector circuit including a plurality of data registers connected in parallel via corresponding output buffers to a plurality of output drivers, wherein a decoder and selector portion is interposed between the output buffers and the output drivers for selectively providing one of a plurality of serial data output sequences from the data registers to the output drivers rather than a parallel data output format from the plurality of data registers which would otherwise occur. The decoder and selector portion is controlled by a partial address buffer which is provided with serial sequence selection data. Upon decoding the serial sequence selection data of the partial address buffer, a plurality of MOS transistors included in the selector portion are rendered conductive in sequence in response to respective control signals applied to the gates thereof to connect the plurality of data registers via their output buffers to respective output drivers in a sequence determined by the decoded selection data of the partial address buffer for serial data output in the selected serial data output sequence.
摘要:
A data processing system capable of specifying impeding factors that impede power savings is disclosed. The data processing system includes a central processing unit, an operation mode detection unit, and an impeding factors specifying unit. The central processing unit has multiple operation modes, and each of the operation modes has a different rate of power consumption. The operation mode detection unit detects an operation mode of the central processing unit. Based on a history of operation modes of the central processing unit that was detected by the operation mode detection unit, the impeding factors specifying unit specifies a device that is considered as an impeding factor to power savings for the data processing system.

A user specifies, in advance, the expansion devices which he/she does not want to remove among the expansion devices which are attachable/detachable with respect to the PC, and the specified expansion devices are excluded from a list displayed later for the user to select an expansion device to remove. Besides, whether to display expansion devices in the list is specified to an BIOS and the information referenced by the BIOS is stored in an NVRAM.
摘要:
An information processing apparatus that is driven by a rechargeable battery, wherein the battery is depleted from a fully charged state and repeatedly charged and discharged, comprises a full charge capacity acquisition unit for acquiring a present full charge capacity of the battery which the battery has at the present time, a total charge acquiring unit for acquiring information indicating a total amount of charge provided to the battery in a time period from a start time of using the battery until the present full charge capacity is acquired, and a restoring unit for performing a battery restoration in which the battery is fully discharged or fully charged in order to recover the full charge capacity if it is determined that the present full charge capacity is smaller than an expected full charge capacity that the battery should have depending on the information.
