An electronic device, for example, a laptop computer includes a processor, a transceiver module, for example, a Bluetooth module and a memory. The memory includes a platform proximity agent, which may be implemented as a series of instructions, which when executed by the processor, causes the processor to receive a Bluetooth signal from a corresponding provisioned Bluetooth device, for example, a cellular telephone. Next, determine whether the received signal exceeds both a strength threshold level and a predetermined time threshold level, where the signal strength and time threshold levels are established when the laptop and a corresponding cell phone are paired during a provisioning process. When the received signal strength and duration both exceed the corresponding policy based thresholds, the laptop enters (or remains in) a full power state with full access to the monitor and the platform. On the other hand, when the received signal strength and duration both fall below (or are less than) the corresponding policy based threshold, the laptop enters (or remains in) a reduced power, or locked state.

Methods, devices, systems and computer program products for operating a networked device coupled to an uninterruptible power supply (UPS) are provided. One or more networked devices are programmed with priority information. The one or more networked devices are further programmed to enter a reduced power state based on the priority information following receipt of a power interruption indication signal from the UPS. The power interruption indication signal indicates that power from a primary source of power has been interrupted.

A memory module includes a memory hub that monitors utilization of the memory module and directs devices of the memory module to a reduced power state when the module is not being used at a desired level. System utilization of the memory module is monitored by tracking system usage, manifested by read and write commands issued to the memory module, or by measuring temperature changes indicating a level of device activity beyond normal refresh activity. Alternatively, measured activity levels can be transmitted over a system bus to a centralized power management controller which, responsive to the activity level packets transmitted by remote memory modules, direct devices of those remote memory modules to a reduced power state. The centralized power management controller could be disposed on a master memory module or in a memory or system controller.

Information handling system power management in standby and hibernate states is adapted to reduce transition times for end user requests to resume to an operational state. During fast resume time periods, transitions to the hibernate state are limited so that recovery to an operational states has the reduced resume time associated with the standby state. The fast resume time periods are set by user preference or automatically set by monitoring end user interactions with the information handling system to predict fast resume times appropriate for the end user. In one embodiment, a power manager automatically transitions the information handling system from the hibernate state to a standby state a predetermined time period before a fast resume period begins.

Power down to a reduced power state, such as a standby or off state, of an information handling system is delayed by a user-configured time after detection of closing of the cover of the information handling system. In one embodiment, a cover delay module associated with the BIOS of the information handling system delays communication of the detection of the closing of the cover from the BIOS to a power manager of the operating system that commands the reduced power state. In another embodiment, the cover delay module integrates with the operating system power manager.

A system and method for detecting and predicting neurological events with an implantable device uses a relatively low-power central processing unit in connection with signal processing circuitry to identify features (including half waves) and calculate window-based characteristics (including line lengths and areas under the curve of the waveform) in one or more electrographic signals received from a patient's brain. The features and window-based characteristics are employed within the framework of a programmable finite state machine to identify patterns and sequences in and across the electrographic signals, facilitating early and reliable detection and prediction of complex spatiotemporal neurological events in real time, and enabling responsive action by the implantable device.

A storage device, such as a hard disk drive or solid state drive, reduces energy consumption by entering a reduced power state after an inactivity time where the inactivity time is set based upon I/O commands received at the storage device. For example, where commands received at a storage device are characterized in a predetermined way in terms of read commands, such as a last received command as a read command or a ratio of read commands versus write commands, a first inactivity time is applied, while commands characterized in a predetermined way in terms of write commands have a second inactivity time applied. Using a greater inactivity time during read activities than during write activities provides improved performance with reduced power consumption.

A proposal for power management control of an interconnect structure based on power state transition control. The power state transition is based on generating early warning signals and an idle timeout value setting based on response time and detection of subsequent requests.

A system for monitoring an inventory of golf clubs includes a plurality of golf clubs with wireless transceivers and a monitor that transmits a first interrogation signal to the plurality of wireless transceivers, the first interrogation signal being an invitation for each of the plurality of wireless transceivers to respond with a signal that indicates each transceiver's unique identification code. The monitor interprets each of the response signals received to determine the unique identification code within each signal, compares the set of expected identification codes stored in memory to each unique identification code received at the receiver, determines an absence of reception of at least one unique identification code within the set of expected identification codes, causes the transmitter to transmit a second interrogation signal to at least a one of the plurality of transceivers having the at least one determined absent unique identification code, the second interrogation signal being an invitation for the transceiver having the determined absent unique identification code to respond with a signal that indicates the at least one determined absent unique identification code, determines a continued absence at the receiver of the at least one determined absent unique identification code, and activates a missing club indicator if an amount of time between the determining the absence and the determining the continued absence exceeds a predetermined amount.

In one embodiment, provided is a method that includes detecting disconnect of a link at a Universal Serial Bus (USB) device coupled to a USB host via a USB bus, disconnecting the USB device from the USB bus, and modifying a power state of the USB device to a reduced power state. Disconnecting the USB device from the USB bus includes configuring the USB device such that the USB host recognizes the USB device as being disconnected from the USB bus. The reduced power state allows the USB device to monitor a status of the link such that the USB device is able to detect a reconnect of the link.

A system and method for communicating command parameters between a processor and a memory flow controller are provided. The system and method make use of a channel interface as the primary mechanism for communicating between the processor and a memory flow controller. The channel interface provides channels for communicating with processor facilities, memory flow control facilities, machine state registers, and external processor interrupt facilities, for example. These channels may be designated as blocking or non-blocking. With blocking channels, when no data is available to be read from the corresponding registers, or there is no space available to write to the corresponding registers, the processor is placed in a low power “stall” state. The processor is automatically awakened, via communication across the blocking channel, when data becomes available or space is freed. Thus, the channels of the present invention permit the processor to stay in a low power state.
