Abstract: A plasma arc torch includes an annular baffle defining distinct faces A, B, C, and D. Faces A and C are opposite from each other, and faces B and D are opposite from each other. First passages for fluid flow extend between the faces A and C, and second passages extend between the faces B and D. The baffle is installable in an annular space between an inner wall and an outer wall, in either of two orientations. In a first orientation, the first passages are open to fluid flow and the second passages are closed by engagement of the inner and outer walls with the faces B and D, and in a second orientation, flipped over relative to the first orientation, the second passages are open to fluid flow and the first passages are closed by engagement of the inner and outer walls with the faces A and C.

Abstract: A networked light bulb is disclosed comprising means for controlling a state of the networked light bulb, means for connecting to a network, means for allowing a user to select a color from a plurality of colors, the plurality of colors having at least one locking color and one or more non-locking colors, and means for generating a selected color code corresponding to the color selected by the user, each color of the plurality of colors having a corresponding color code. If the user selects the locking color, the networked light bulb disconnects from the network and turns the light bulb on. If the user selects a non-locking color, the networked light bulb submits the selected color code over the network for use by the network controller in configuring the device and changes the state of the networked light bulb in response to a command from the network. In some embodiments the networked light bulb also responds to requests for status information from the network independent of the color selected by the user.

Abstract: A power node provides energy management and network expansion features in a networked data communications and control environment that may be utilized in an energy management system implementing a method of managing energy. Network expansion may be provided by integrating a networking bridge from a power line network to one or more wired network ports or a wireless network. The power outlet on the power node providing power to a device may be identified and associated with information about the device.

Abstract: A control has up, down, left, and right controls, with a select control located adjacent to the directional controls (e.g., in the center) to allow a user to move an erroneously entered key on a virtual keyboard to a desired key and to select the desired key without requiring the user to take the user's eyes away from the virtual keyboard and to move the user's hands significantly. The virtual keyboard may be displayed on the control or on a separate remote device, such as a television.

Abstract: In one embodiment, an apparatus comprises a communication interface for receiving content from a content source, a display interface for coupling to a display, a processor for manipulating the content in a form so that it can be transmitted over the display interface and presented on the display, a memory coupled to the processor for storing instructions to implement a user interface, the user interface being operable for navigating the content, and a user input section for receiving input from a user. The processor is operable to present the user interface on the display and dynamically change the user interface as at least one of an amount of content changes or the frequency of selecting content by the user changes.

Abstract: A method of fabricating an electrode is disclosed, wherein the electrode comprises a copper holder defining a cavity in a forward end. An emissive element and separator assembly is positioned in the cavity. An intermetallic compound is formed between the emissive element and the separator by heating a relatively non-emissive material until it melts and dipping the emissive element therein before cooling the assembly. As a result, the intermetallic compound is formed significantly faster than by conventional methods.

Abstract: A gas pressure reducing regulator which includes a flexible diaphragm which is biased by a spring so as to control the opening of the valve of the regulator and thus the delivery pressure of the gas being regulated. The regulator includes a system for effectively containing an accidental oxygen fire, or the like, within the body of the regulator, and protecting the internal components from ignition. The system includes a plunger which resides in an axial bore in the regulator body and shields the diaphragm from hot combustion products, and plunger-retaining features which prevent the plunger from being displaced from its axial bore. Also, the regulator has provision for venting the interior of the regulator to the atmosphere in the event of an excessive overpressure therein.

Abstract: A post-mixed cutting torch selectively operable in a pilot mode and a cutting mode is provided by the present invention. The control body includes a fuel passage and an oxygen passage which is divided into a preheat oxygen supply branch and a cutting oxygen supply branch. A fuel flow valve is provided in the fuel passage and an oxygen flow valve is provided in the cutting oxygen supply branch of the oxygen passage. Advantageously, an interconnecting passage extends between the preheat oxygen supply branch and the cutting oxygen supply branch. Accordingly, the torch is operable in a preheat/cutting mode wherein oxygen is directed through both the preheat and cutting oxygen apertures of a cutting nozzle. In addition, each of the fuel and oxygen flow valves is associated with a bypass channel which allows the torch to be operable in a fuel saving pilot mode wherein oxygen is directed through both the preheat and cutting oxygen apertures of a cutting nozzle.
