A wireless electrical power metering system is provided. A processor having a multichannel power line transceiver, a wireless transceiver, and a power meter attached thereto measures power consumption information at a location. The processor converts the power consumption information into IP-based data, and transmits same over the wireless transceiver. The information can be wirelessly received by a remote monitoring station or transmitted across the Internet for storage, analysis, and billing. The processor can remotely control appliances in response to power consumption trends. The processor can relay information between a wired or wireless network and a power line network, to allow multiple dwellings to be networked using power lines, and households to be connected to the Internet via a power line network. The electrical power metering system also includes Global Positioning System (GPS), biometric scanning, emergency alert reception, and environmental monitoring capabilities.

A motor controller (4) and method for maximizing the energy savings in an AC induction motor (3) at every load wherein the motor is calibrated at two or more load points to establish a control line (6), which is then programmed into a non-volatile memory (30) of the motor controller. A DSP-based closed-loop motor controller observes the motor parameters of the motor such as firing angle / duty cycles (23), voltage (37), current (9) and phase angles to arrive at a minimum voltage necessary to operate the motor at any load along the control line. The motor controller performs closed-loop control to keep the motor running at a computed target control point, such that maximum energy savings are realized by reducing voltage through pulse width modulation.

The invention discloses a building outer wall structure with double shaping phase change material layers. The building outer wall structure sequentially comprises the outer shaping phase change wall board layer, a first thermal insulation layer, a wall body layer, a second thermal insulation layer, the inner shaping phase change wall board layer from outside to inside, wherein the outer shaping phase change wall board layer and the inner shaping phase change wall board layer are respectively made of phase change materials of phase change temperatures of Tm1 and Tm2, the phase change temperature Tm1 is set to be minimum in cold load all year round in the expositing environment of the phase change temperature Tm1, and the solid phase change materials melt into liquid phase change materials when the wall board layer temperature is equal to or higher than Tm1; the phase change temperature Tm2 is set to be minimum in heat load all year round in the exposing environment of the phase change temperature Tm2, and the solid phase change materials melt into liquid phase change materials when the wall board layer temperature is equal to or higher than Tm2. The invention further designs the components and proportion of the phase change materials of the two shaping phase change wall board layers. By the building outer wall structure which is compact, high in adaptability, convenient to manufacture and maintain later, and the like, outer wall cold load and heat load can be lowered effectively, and overall energy consumption is lowered evidently.
