  • Publication number: 20170026193
    Abstract: An internet protocol based audio alert system for managing security across a site has a network of a central server computer (12), a central client computer (14) and a remote client computer (30) communicating across the internet (16) with a plurality of programmable edge devices (18). The programmable edge devices (18) control the operation of an audiovisual input unit and an audiovisual output unit (20, 22, 24, 26) located across the site. The programmable edge devices (18) are programmed with software to enable them to store alert messages, which are short alert messages, and send the alert messages to the audiovisual output element where the alert messages are broadcast in response to triggers received by the audiovisual input unit. The audiovisual output unit include a loudspeaker assembly (22) connected to each programmable edge device.

  • Publication number: 20170009329
    Abstract: The present disclosure is directed to an electric current sinterable material containing a minority portion being significantly more electrically conductive than the primary material being sintered. This includes forming an inorganic body or sintered coating as well as an apparatus for and method of making use of such a variable composition powder. An electrical current is used to cause a combined energy and temperature profile sufficient for powder-powder sintering. This preferred method for powder-substrate bonding is referred to as flame-assisted flash sintering (FAFS).

  • Publication number: 20170001918
    Abstract: The present disclosure is directed to a variable sintered coating or a variable microstructure coating as well as an apparatus and method of making such a variable coating onto substrates. The substrate has some electrical conductivity and is used as one electrode while an ionized gas is used as the other electrode that is moved over the areas of the powder coating to be sintered. An electrical current is used to cause a plasma produced through the gas, resulting in a combined energy and temperature profile sufficient for powder-powder and powder-substrate bonding. This preferred method is referred to as “flame-assisted flash sintering” (FAFS).

  • Publication number: 20160363971
    Abstract: A thermal control system that includes a combination of active and passive components is described herein. In one or more implementation, the thermal control system compensates for non-uniformities in a temperature profile for an arrangement of components within a computing device. One or more active components of the thermal control system transfer heat away from heat-generating devices by active means, such as active transfer to a moving fluid that is driven by a blower or fan. Additionally, one or more passive components are positioned to transfer heat to selected areas of the device using passive transfer devices, such as heat-pipes and thermal spreaders made of conductive materials. The active and passive components operate together to compensate for temperature variations across the device surfaces, produce a controlled temperature profile having greater uniformity, reduce overall differences in surface temperatures, and provide greater capability for heat dissipation.

  • Publication number: 20160348247
    Abstract: The present disclosure is directed to an apparatus and method of sintering inorganic powder coatings on substrates, and includes a flame and an electric plasma. The method is capable of being used in an open atmospheric environment. The substrate is electrically conductive and is used as one electrode while the flame is used as the other electrode that is moved over the areas of the powder coating to be sintered. An electrical current is used to cause a plasma produced through the flame, resulting in a combined energy and temperature profile sufficient for inorganic powder-powder and powder-substrate bonding. This method is referred to as “flame-assisted flash sintering” (FAFS).

  • Patent number: 9462348
    Abstract: In a broadband communications system, e.g., a cable system, programming content can be readily reserved and accessed for viewing using an interactive program guide, a network home graphic user interface (GUI), Quick View Guide, etc., in accordance with the invention. Such programming content may include in-progress programs, future programs and previously broadcast programs which are recorded at a headend in the cable system, and which may or may not have overlapping broadcast times. In addition, the user may reserve programs at a set-top terminal, and may also do so remotely from the terminal through a communications network such as, the Internet, a public switched telephone network (PSTN), a wireless telephone network, etc.
