The invention generally concerns systems and methods for monitoring and controlling the power consumption of a power-consuming device. The system and method may connect to a power source and a power-consuming device, connecting the power-consuming device to the power source. The power usage of the power-consuming device may then be measured and monitored. This monitoring data may then be stored and optionally sent to a controlling device on a data network. The location of the power-consuming device may also be determined, recorded, and sent to a controlling device. The system may also control the power usage of the power-consuming device. In some cases, a remote server may connect multiple energy monitoring systems in order to gain additional efficiencies and foster a community-based social network.

In one exemplary embodiment, a restriction system for forming a restriction in a patient is provided and can include an implantable restriction device and at least one implantable sensor that is in communication with the restriction device. In general, the implantable restriction device can be adjustable and can be configured to form a restriction in a patient. The implantable sensor(s) can be defaulted to a dormant power usage mode and can have a triggering mechanism that is configured to place the sensor(s) in a use configuration upon the occurrence of a triggering event.

Methods and apparatuses for circuit design to reduce power usage, such as reducing temperature dependent power usage, and/or to improve timing, such as reducing temperature dependent delay or transition time. At least one embodiment of the present invention reduces the power dissipation and improves the timing of an integrated circuit to optimize the design. A thermal analysis is used to determine the temperature dependent power dissipation of a circuit and the temperature distribution of the circuit resulting from dissipating the heat created by the temperature dependent power dissipation. Then, the components of the design are selectively transformed to reduce the power dissipation and to improve timing based on the temperature solution. The transformation may include placement changes and netlist changes, such as the change of transistor threshold voltages for cells or for blocks of the circuit chip.

A load management system controller employs a method for determining carbon credits earned as a result of a control event in which power is reduced to at least one service point serviced by a utility. The controller is located remotely from the service point(s) and determines power consumed over time by at least one device located at the service point(s) to produce power consumption data. The controller stores the power consumption data. At some later point in time, the controller initiates a control event and determines an amount of power reduced during the control event based on the stored power consumption data. The controller also determines a generation mix for power that would have been supplied to the service point(s) if the control event had not occurred. The controller then determines a quantity of carbon credits earned based at least on the amount of power reduced and the generation mix.

The invention may be embodied in a method for operating a disk drive in a mobile device to optimize power usage. The mobile device may be a hand held computing device such as a personal digital assistant (PDA) or a mobile terminal such as a cellular telephone. Immediately after responding to a disk access command, the disk drive is in first operating mode that consumes a relatively high level of power and may transition to a second operating mode that consumes a relatively low level of power. A transition from the second operating mode to the first operating mode consumes a transition quantity of power. A predictive technique tracks a user's usage pattern and adapts an operating mode transition time based on the usage pattern.

A method and apparatus are disclosed for performing adaptive run-time power management in a system employing a CPU and an operating system. A CPU cycle tracker (CCT) module monitors critical CPU signals and generates CPU performance data based on the critical CPU signals. An adaptive CPU throttler (THR) module uses the CPU performance data, along with a CPU percent idle value fed back from the operating system, to generate a CPU throttle control signal during predefined run-time segments of the CPU run time. The CPU throttle control signal links back to the CPU and adaptively adjusts CPU throttling and, therefore, power usage of the CPU during each of the run-time segments.

The invention may be embodied in a method for operating a disk drive in a mobile device to optimize power usage based on an application category. The mobile device may be a hand held computing device such as a personal digital assistant (PDA) or a mobile terminal such as a cellular telephone. A technique of the invention may spin down the disk drive after an adjustable delay time interval that is set based on an application category associated with a most recent data transfer command.

A mobile device may include a geopositioning receiver and an accelerometer, which may be engaged in an alternating manner depending on whether the mobile device is at rest or in motion. If the mobile device is in motion, the geopositioning receiver may remain engaged to provide a real-time location of the mobile device, which may be used to generate various location-triggered notifications and to control location-triggered applications. If the mobile device is at rest, the geopositioning receiver may be disengaged to reduce power usage and instead the accelerometer may be engaged to monitor whether the mobile device is put back in motion. If so, the geopositioning receiver may be reengaged. A sequence of locations where the mobile device came to rest may be stored to construct a location profile, which may allow closely targeted offers and advertisements to be generated based on the daily activity patterns of users.

A method and apparatus for controlling power consumption of a facility, building or simply a collection of one or more devices, by load shedding when power consumption is above, or is predicted to be above, a preselected setpoint, but only if electrical power on the spot market cannot be purchased at or below a preselected price. The apparatus and method of the invention optimizes power usage by taking advantage of the buying of electricity as a commodity on the spot market. As a further aspect of the invention, in the situation of a supermarket for example, which refrigerates food products, artificial product core temperature sensors or direct insertion product sensors can be used to continuously monitor the refrigerated temperature of perishable products. A controller would constantly monitor these temperatures to allow a precise load shedding routine to be implemented.
