    摘要： Systems and methods for peer data storage device messaging over a control bus for power management are disclosed. Storage devices may include a host interface configured to connect to a host system and a control bus interface to connect to a control bus. Peer data storage devices may establish peer communication through the control bus interface, determine a power state, receive a power change indicator from a peer data storage device, and initiate a change in their power state. The peer data storage devices may manage their collective power as a power pool and increase or decrease power use without host intervention.

    摘要： A power supply control device controls charging and discharging of a power supply device including a plurality of power supply units which are connected in parallel to a load and a power generation unit. The power supply control device has relationship information indicating a relationship among a discharge current flowing from the power supply device to the load, a discharge current ratio that is a ratio of output currents of the plurality of power supply units, and a power loss of the power supply device, acquires a measured value of the discharge current, obtains, from the relationship information, the discharge current ratio at which the power loss of the power supply device corresponding to the acquired measured value of the discharge current is minimized, and adjusts the discharge current ratio so as to match with the discharge current ratio obtained from the relationship information.

    摘要： There are provided a sensor data collection device, a sensor data collection system, and a method of collecting sensor data capable of reducing a drain of a battery due to standby power. The sensor data collection device includes a power supply, a power supply control circuit configured to control the power supply, a sensor configured to perform sensing to thereby obtain data, a memory configured to store the data obtained by the sensor, and a control circuit configured to control the power supply control circuit, the sensor, and the memory. The power supply control circuit supplies the sensor, the memory, and the control circuit with electrical power supplied by the power supply, and the control circuit makes the transition to any one of a plurality of operating states, and makes the power supply control circuit shut off the electrical power supplied by the power supply after a first operating state is completed and before the transition to a second operating state is made wherein the first operating state and the second operating state are included in the plurality of operating states.

    摘要： Methods, systems, and devices for shallow hibernate power state are described. A memory system may include a memory array and a controller. The memory system may transition from a first power state having a first current to a second power state having a second current less than the first current, where the first power state is associated with executing received commands and the second power state is associated with deactivating one or more components of the memory array. The memory system may initiate a timer after transitioning from the first power state to the second power state. The memory system may determine the timer satisfies a threshold and transition from the second power state to a third power state having a third current less than the second current based on the timer satisfying the threshold.
