  • Patent number: 10318895
    Abstract: A method of promoting more efficient use of a resource includes acquiring values associated with consumption of a resource by an entity at a place (for example, a building, a floor, or a wing of a building). A normalization of the values may be performed. While the resource is being consumed at the place, comparisons based on the normalized values associated with consumption of the resource at the place and one or more other values associated with consumption of the resource are displayed to one or more persons of the entity. In some cases, consumption of the entity is compared with consumption by one or more other entities (for example, in a graph comparing one company's consumption for the week with that of another company.

The IC includes a functional circuit configured according to a first value of a parameter related to EM tolerance. The IC also includes a dummy version of the functional circuit configured according to a second value of the parameter. The second value causes the dummy version of the functional circuit to be more sensitive to an EM event than the functional circuit. Upon the EM monitor determines that the EM event occurs in the dummy version of the functional circuit, the EM monitor asserts a signal indicating that the EM event has occurred in the dummy version of the functional circuit and providing a warning that the EM event is likely to occur in the functional circuit.

  • Patent number: 9523718
    Abstract: The invention relates to a disaggregation apparatus for identifying an appliance in an electrical network (2) comprising multiple appliances (3, 4, 5). A voltage meter (7) measures a first change in a mains voltage (V) delivered to the appliances of the electrical network, while an operational state of an appliance is modified, and a second change in the mains voltage, while a switchable load is switched. An appliance determination unit (9) determines the appliance, of which the operational state has been changed, based on the measured first change in the mains voltage, the measured second change in the mains voltage and the resistance of the switchable load. Thus, an appliance can be determined without detecting switching flickers in very short time durations, i.e. high sampling rates and continuous monitoring are not necessarily required. This reduces the technical efforts of the disaggregation apparatus for performing the disaggregation function.

  • Patent number: 9249562
    Abstract: The present invention provides a water supply apparatus capable of performing a backup operation, without lowering water supply capability, when a failure has occurred in one control substrate due to surge or noise caused by lightning or due to lifetimes of various sensors, by switching to the other control substrate, and capable of reliably performing the backup operation by means of devices that prevent failure of the control substrates. The water supply apparatus (1) includes: a plurality of pumps (3); a plurality of inverters (INV) each configured to change and control a rotational frequency of a corresponding one of the plurality of pumps (3); and a plurality of control substrates (CN) configured to control the plurality of inverters (INV).

  • Patent number: 9235250
    Abstract: A mechanism is provided for customized power rating for computer equipment. A power monitor determines actual power consumption by computer equipment in a facility. After equipment has been stressed, an operator sends the actual power consumption information to the manufacturer. The manufacturer receives the actual power consumption information and issues a certificate that acknowledges the equipment will not consume more power than what was measured. The manufacturer may provide digital media that instructs power management hardware in the computer equipment to adhere to an actual case power limit. The power management hardware treats the actual case power limit as a hard power limit. That is, the power management hardware will not specify a power cap higher than the actual case power limit. The power management hardware prevents the equipment from crossing the actual case power limit.

  • Patent number: 9167023
    Abstract: A system for power measurement in an electronic device includes a sensing unit, an analog-to-digital converter (ADC) and a controller. The sensing unit senses voltage across a power source and modulates a carrier signal based on the sensed voltage. The ADC converts a combination of the modulated carrier signal and audio signals received by the electronic device to generate a digitized combined signal and provides the digitized combined signal to the controller. The controller separates digitized modulated carrier signal and digitized audio signals. The digitized modulated carrier signal is demodulated to generate an output signal that provides a measure of the power consumed by the electronic device.

  • Patent number: 9153235
    Abstract: One or more test features are extracted from a time domain signal. The test features are represented by discrete data. The discrete data is represented for each of the one or more test features by a corresponding one or more fitting functions, which are defined in terms of finite number of continuous basis functions and a corresponding finite number of expansion coefficients. Each fitting function is compressed through Functional Principal Component Analysis (FPCA) to generate corresponding sets of principal components. Each principal component for a given test feature is uncorrelated to each other principal component for the given test feature. A distance between a set of principal components for the given test feature and a set of principal components for one or more training features with the processing system is calculated. The test feature is classified according to the distance calculated with the processing system.
