Power control for environmental control components (e.g. lighting, blinds, temperature) is controlled and distributed by a regulated power controller in accordance with user preferences and/or a schedule. The outputs of the regulated power controller include at least one regulator capable of a mixed mode output, operable in any of several output modes that can include DC regulation and pulse width modulation, as well as polarity inversion. The centralized control of electrical power facilitates the coordination of environmental control components for holistic control.

Environmental control system and regulated power controller for same

An LED bulb includes one or more LEDs that have a forward voltage that is dependent on the thermal temperature of the LEDs. In some embodiments the LED bulb includes a temperature sensor that provides an indication of LED temperature to a power supply so that the voltage provided to the LED bulb by the power supply is optimized and adjusted with respect to temperature so that only the voltage needed by the LED bulb to power the LEDs to an desired light output level is provided to the LEDs, and overhead voltage is minimized.

Light emitting diode bulb, control system and apparatus

An LED lamp is powered by an external current regulated (constant current) power supply. The LED lamp provides a signal to the power supply to adjust the output current of the power supply to achieve and maintain a desired light output level. The signal is adjusted as the temperature of the LED lamp changes in order to ensure consistent light output of the LED lamp as the LED lamp changes temperature during operation.

Method and apparatus for controlling light output from a LED lamp

A tubular LED bulb includes a circuit board include an AC to DC conversion circuit that provides an output DC current at one of several selectable levels when provided with an AC power source. The DC current is routed through a plurality of LEDs at the selected DC current level. The AC to DC conversion circuit operates responsive to a selection circuit that allows a user to select a level corresponding to a desired light output level. The AC to DC conversion circuit allows the tubular LED bulb to be mounted in a conventional fluorescent light fixture, including a ballast, without regard to polarity. In some embodiments, the circuit board includes jumper blocks to allow multiple circuit boards to be connected in tandem.

The present invention discloses a portable computing device () including a processor (), alternate memory (), and a DRAM memory (). Under normal operating conditions, providing full functionality of the device, a full code instantiation in the DRAM is executed, providing operating system, user interface and application execution functionality. A reduced code instantiation () which duplicates certain elements of the operating system, user interface, and application code is maintained in the low power memory. When a condition occurs that dictates or allows, execution is switched from the full code instantiation to the reduced code instantiation, and the DRAM is shut off.

The present invention discloses a portable computing device () including a processor (), non-volatile memory (), and a volatile memory (). An execute in place (XIP) kernel () stored in the non-volatile memory is executed immediately upon powering up the device. As the XIP kernel is executed, the processor maintain state and context information () in the volatile memory. The XIP kernel includes user interface and application segments, allow the user to perform some functions immediately upon powering up the device. While executing the XIP kernel and full code instantiation () is loaded into the volatile memory. The full code instantiation includes identical code as is in the XIP kernel, in addition to other code. Once loaded, execution is switched () from the XIP kernel to the full code instantiation, providing full functionality of the device.
