摘要： An active power conditioner, connecting with a load and a power source in parallel, includes a DC power capacitor, a power converter, a high-frequency filter and a control circuit. The control circuit detects the voltage of the DC power capacitor and the current of the power source, thereby performing a closed loop control to stabilize the voltage of the DC power capacitor and performing a feed forward control to generate a driving signal for driving the power converter. The power converter actuates the DC power capacitor to supply a current via the high-frequency filter to reduce the reactive and harmonic components of load current. The load is converted to the linear resistance characteristic, observed from the power source side.

摘要： A modularized active power filter includes a control module and at least one power module. The control module automatically identifies the number of the parallel connected power modules and generates one set of PWM signals to correspondingly control the parallel connected power modules, so as to provide a final compensation current by single power module or plural power modules. Thereby, the compensation demand of a load is met. Consequently, the modularized active power filter is able to improve the flexibility of compensation capacity, shorten the time for service, be suitable for mass production, and lower the manufacturing cost.

摘要： The claimed subject matter relates to an architecture that can facilitate rich interaction with and/or management of environmental components included in an environment. The architecture can exist in whole or in part in a housing that can resemble a wand or similar object. The architecture can utilize one or more sensor from a collection of sensors to determine an orientation or gesture in connection with the wand, and can further issue an instruction to update a state of an environmental component based upon the orientation. In addition, the architecture can include an advisor component to provide contextual and/or comprehensive guidance in an intuitive manner.

摘要： Systems, methods and computer-storage media are provided for identifying low-match search queries and determining comparable item matches to suggest to the user in response to a low-match query. “Low-match queries” are queries for which an insufficient number of exact item matches are available. In embodiments, exact and/or comparable item matches may be determined via semantic analysis. Also provided are systems, methods and computer-storage media for informing the user, by way of a presented indicator, or the like, that a presented item was selected for presentation based upon a similarity metric rather than being determined an exact match for the input query.

摘要： Methods and computer-storage media having computer-executable instructions embodied thereon that facilitate refining query results using visual cues are provided. Query results are determined in response to an indication of a user query. One or more groups of query results are generated from the query results based on categories of query results that share similar features. Visual cues are associated with each of the query result groups. Visual cues, in association with query result groups, are presented to a user. Query results associated with a selected visual cue may be presented to a user. A refined user query may be generated based on a selected visual cue.
