  • Publication number: 20090055026
    Abstract: The present invention provides methods and apparatuses for controlling an environmental system with an adjustable speed motor from environmental information received through a network A network controller receives differential environmental information through the network. A motor controller, which controls the speed of the variable speed motor, obtains the received differential environmental information from the network controller, determines a desired speed of a variable speed motor of the environmental system based on the received differential temperature, and adjusts the operating speed of the variable speed motor to approximate the desired speed. The network controller further receives discrete environmental information through the network, where the discrete environmental information includes at least one measured environmental factor and an environmental set point.

  • Publication number: 20080266846
    Abstract: The present invention supports a solar lamp that includes a solar panel that charges a battery to power a display panel and a processor. Based on environmental factors measured by a sensor, the processor instructs the display panel to change colors based on the value of an environmental factor. If the measured environmental factor changes values, the processor may subsequently instruct the display panel to change colors. The solar lamp may be controlled by a remote controller. The solar lamp has a receiver circuit that receives control data from the remote controller to configure the display panel. Based on the control data, a processor may instruct the display panel to change colors or change intensity. The remote controller controls a solar lamp through a wireless communications channel. Based on an indication, a processor sends control data through a wireless transmitter circuit to configure the display panel of the solar lamp.
