摘要:
A heat pump water heater and systems and methods for its control are disclosed. The systems are configured to heat water within a water storage tank of a heat pump water heater wherein a controller within the system is operatively connected to a plurality of heat sources including at least one electric heating element and a heat pump and sensors in order to selectively energize one of the plurality of heat sources. The controller is configure to process data representative of the temperature of water within the tank near the top of the water storage tank, and rate of water flowing out of the water storage tank, in order to automatically selectively energize the heat sources. The selection of heat sources by the controller is determined by a mode of operation selected by the user and the data processed by the controller in view of the selected mode of operation.

Methods (200) and a system are disclosed for one or more appliances (102, 104, 106) including a controller (110) for managing power consumption within a household. The controller (110) is configured to receive and process a signal (112) indicative of one or more energy parameters of an associated energy utility, including at least a peak demand period or an off-peak demand period. A generated serial number is obtained from an original serial number (108) of the appliance (102, 104, 106) or controller (110), which is configured for a signal (112) to communicate to the appliance (102, 104, 106) within a population and command the appliance (102, 104, 106) to operate in an energy savings mode and a normal mode at various time periods. The generated serial number (GSN) is used to segregate a total population into segments to provide granularity in assigning DR activations and deactivations based upon the GSN.

A system includes an estimating unit (21) to non-destructively estimate a fat content and a water content of a food sample (S). The system further includes a processing unit (29) operatively coupled to the estimating unit (21) to determine a calorie content based solely on the fat content and the water content of the food sample (S). The estimating unit (21) may include a microwave spectrometer (70) with a transmitter (22a) and a receiver (22b). The transmitter (22a) can be capable of transmitting microwaves (W) of multiple frequencies through a food sample (S). The received signal can then be compared to the transmitted signal to estimate the fat content and water content.
摘要:
Disclosed is a dual-purpose lamp (1), which comprises a power-converting module (10), a light-emitting module (20) and a control unit (40). The power-converting module (10) is used for generating a direct current. The light-emitting module (20) is electrically connected with the power-converting module (10), the light-emitting module (20) comprises an illuminative light-emitting body (21) and a scenario light-emitting body (22), and the illuminative light-emitting body (21) and the scenario light-emitting body (22) are connected with each other in parallel. The control unit (40) is electrically connected with the power-converting module (10) and is used for controlling the power-converting module (10) so as to adjust the brightness of the illuminative light-emitting body (21) when light is emitted, or to adjust the color, the brightness or the chroma of the scenario light-emitting body (22) when light is emitted.
