摘要:
Systems and methods are described that allow a user to mix multiple sources of multimedia content from the Web, such as social network accounts, RSS feeds, and other sources of multi-media content. Each of the sources of content, independent of the format and content, is transformed into a homogeneous content container called a frame, and the frames are organized into a cycling chain of content referred to as a stream. The streams are displayed in real-time on a client device as customized multi-media streams. Users can share frames and/or streams with other users.

An automatic power factor correction system, for an electrical power installation drawing varying levels of reactive power, measures an electrical parameter of the power drawn by a load of a power installation which is capable of indicating a level of reactive power drawn by the load and couples a combination of capacitors to the power line to compensate for the level of reactive power indicated by the electrical parameter measured. In particular, the system measures the phase angle of the power drawn and calculates a combination of capacitors to connect to the power line to compensate for a measured level of reactive power.

An automatic power factor correction system, for an electrical power installation drawing varying levels of reactive power, measures an electrical parameter of the power drawn by a load of a power installation which is capable of indicating a level of reactive power drawn by the load and couples a combination of capacitors to the power line to compensate for the level of reactive power indicated by the electrical parameter measured. A first embodiment of the system is based on a measured level of current and the effect on the measured level of current of adding compensating capacitors of selected capacitances to the power line. A second embodiment of the system is based on a measurement of phase angle of the power drawn and the addition of a calculated combination of capacitors to the power line to compensate for a measured level of reactive power.

A system renders an object as a plurality of layers displayed within a three-dimensional view. The system receives a selection of a layer from the plurality of layers in the three-dimensional view, and renders the object as a planar view with the selected layer active, the planar view displaying the object in a two dimensional space.
摘要:
An automatic power factor correction system, for an electrical power installation drawing varying levels of reactive power, measures an electrical parameter of the power drawn by a load of a power installation using a power measurement integrated circuit, the parameter being capable of indicating a level of reactive power drawn by the load, and couples a combination of capacitors to the power line to compensate for the level of reactive power indicated by the electrical parameter measured. In a first embodiment of the invention, the combination of power factor compensating capacitors is calculated from a signed value of reactive power drawn by the load. In a second embodiment, the compensating capacitor combination is calculated from a value of power factor for the load which is calculated from a ratio of an active power value to an apparent power value.
