Abstract: Methods and systems for powering-off a wireless communication device from a linked device are provided. A device can transmit a wireless communication signal to a linked device to instruct the linked device to power-off. In this manner, the user need only turn off one device manually which results in all linked devices being powered off. This process can be initiated by a user through a device directly linked with the device to be powered-off or through a device that is indirectly connected, through one or more wireless communication networks, with the device to be powered-off. This process can also be automatically initiated by a device when a set of predetermined conditions exist. Once instructed to do so, a device can initiate a predetermined power-off process which can involve terminating any ongoing functions and turning off various subsystems. In accordance with the present invention, a user can initiate a power-off of all the devices on a wireless communication network through a single device.

Abstract: A mechanism of booting up a system directly from a storage device and a means of initializing an embedded system prior to activating a CPU is presented. The said system is comprised of one or more CPUs, a reset controller, a storage device controller, one or more direct memory access controllers, a RAM and its controller, a ROM and its controller, a debug interface and a power-on reset (POR) sequencer. The POR sequencer controls the overall boot process of the embedded system. Said sequencer uses descriptors (POR Sequencer descriptors) which are used to update the configuration registers of the system and to enable CPU-independent data transfers with the use of DMA controllers. Using a minimal amount of non-volatile memory for booting up a system brings down costs associated with increased silicon real estate area and power consumption. Capability of pre-initializing the system even before a CPU is brought out of reset provides flexibility and system robustness.

Abstract: Thermal management in a portable computing device differentiates between a temperature increase caused by a steady workload and a temperature increase caused by an instantaneous workload. If it is determined that a detected temperature increase is caused by a steady workload, then a configuration of thermal parameters is applied that optimizes thermal performance for a steady workload. If it is determined that a temperature increase is caused by an instantaneous workload increase, then a configuration of thermal parameters is applied that optimizes thermal performance for an instantaneous workload.

Abstract: A hardware security module (HSM) transitions a first signal from a first state to a second state and transitions a second signal from a first state to a second state when a request to change boot code is received. In response to receipt of a boot request, the HSM, when the first signal is in the first state and the second signal is in the first state: does not execute the hash function; and maintains the second signal in the first state. An actuator control module, in response to the receipt of the boot request: executes the boot code when the second signal is in the first state; and does not execute the boot code when the second signal is in the second state.

Abstract: A rack-power control module (RPC) module is used for allowing a local storage partition, located on a local server, for controlling a destination storage partition, located on a destination server, by piggybacking commands on power alerts issued by the RPC module in a clustered storage system. The commands are sent from the local storage partition to the RPC module, where the commands are RPC commands and include a destination server identification (ID) and payload data that includes a hypervisor command containing a command type, a subtype, and a destination ID. The RPC module then parses the commands received from the local storage partition.

Abstract: Power and thermal management that uses trigger circuits to activate power telemetry. A power consumption level of a subsystem is monitored using a trigger circuit while power telemetry mode for the subsystem is inactive. When the monitored power consumption level exceeds a threshold, the trigger circuit activates the power telemetry mode of operation in which telemetry information of the subsystem is provided to a controller. Power consumption of the subsystem is then managed by the controller based on telemetry information obtained under the power telemetry mode. The controller can determine whether a power consumption level of the subsystem has dropped below a threshold, based on telemetry information obtained under the power telemetry mode. The controller may terminate the power telemetry mode when the power consumption level has dropped below the threshold. Other embodiments are also described and claimed.
