A device may include a control unit to control determination of a processing mode of at least two processing modes and in which an application is executed. The at least two processing modes may include a first processing mode in which the application is executed based on first identification information directly indicating the application and a second processing mode in which the application is executed based on second identification information indirectly indicating the application, where the first identification information and the second identification information are transmitted from an external device through a communication channel.

A system includes storage devices storing data units. Each data unit is stored on one of the storage devices. The system includes a processor, and a non-transitory computer-readable data storage medium storing computer-executable code. The processor executes the code to correlate workloads to the data units with respect to which of the workloads access which of the data units, and when the workloads access the data units. The processor executes the code to when the workloads access the data units and/or and on which of the storage devices the data units are stored, so that at given times the data units stored on a subset of the storage devices are not being accessed by any workload. The processor executes the code to, during each given time, power off the subset of the storage devices storing the data units that are not being accessed by any workload to conserve power.

A display device is configurable to be operable in a first mode and a second mode. The display device includes an emission surface configured to output image light, a first optical assembly, and a second optical assembly. The first optical assembly is configured to receive image light from the emission surface and to direct the image light toward the eyes of a user at a first optical power. The second optical assembly includes a first region configured to receive image light from the emission surface and to direct the image light toward the eyes of a user at a second optical power. The second optical assembly also includes a second region configured to receive ambient light and to transmit at least a portion of the received ambient light at a third optical power distinct from and less than the first optical power and the second optical power.

A server including a first storage unit, a control unit, and a host is provided. The first storage unit enters a first sleep mode or a second sleep mode according to a first control signal. When operating in the first sleep mode, the storage unit has a first power consumption value. When operating in the second sleep mode, the storage unit has a second power consumption value that is different from the first power consumption value. The control unit adjusts the first control signal according to a switching signal. The host generates the switching signal according to an access state of the first storage unit.

A method of operating a computer that is in a sleep state and that is accessed remotely. The method includes receiving an indication that the computer should transition from a sleep state to a wake state, determining whether the indication was generated as a result of a remote access to the computer, and upon determining that the indication was generated as a result of a remote access to the computer, causing the computer to transition to a partial wake state.

An information processing apparatus includes a monitoring unit that monitors a reception of a power-on instruction from a second control device among the plurality of control devices, and a prevention unit that prevents an issue of the power-on instruction to the second control device when the monitoring unit detects the power-on instruction from the second control device. Therefore, the control device can prevent the occurrence of unintended power-on operations.

Some embodiments of the invention relate to selecting a data protection scheme, such as, for example, mirroring or RAID, for a content unit based on power-related metadata associated with the content unit. The data protection strategy selected for a content unit may impact the amount of power that a storage system consumes.
