  • Publication number: 20120219137
    Abstract: A teleconferencing system has a teleconference bridge provided by software executing on one or more computerized servers in a network, the bridge having an access telephone number or address, and a plurality of signal processing banks coupled to the teleconference bridge. The bridge answers incoming calls with an automated message asking for a conference code, assigns a specific bank of processors having a specific maximum call capacity for a teleconference associated with a first incoming call asserting a specific conference code, connects a second incoming call asserting the same conference code in live conference with the first incoming call asserting the same code, connects further incoming calls asserting the same conference code in conference with the first two, tracks the number of calls in a conference as further calls are connected, and connects further banks of processors one-at-a-time as maximum call capacity in already-connected banks is reached.

  • Publication number: 20120195420
    Abstract: A user-operated system for causing a land-line telephone to dial a destination includes a mobile telephony device having a speaker and an internal dual tone multiple frequency (DTMF) dialer, and a dialer extension integrated with a microphone on the land line telephone for capturing a DTMF telephone number sequence. A telephone number is selected on the mobile telephony device, which generates an audible DTMF for the telephone number over the speaker, and the DTMF is captured by the microphone, and the land-line telephone dials the destination.

  • Patent number: 8175243
    Abstract: A teleconferencing system is provided comprising a telephony interface for answering telephony events routed thereto from a router or switch, and one or more signal processing mechanisms coupled to the telephony interface and locatable by the system. The system includes a characteristic of allowing a user to initiate a teleconference to occur on the system, the pending teleconference unbeknown to the system until a first telephony event representing a teleconference participant for the pending teleconference is received at the telephony interface.

  • Patent number: 8172083
    Abstract: An apparatus for supporting liquid-filled containers having removable closures contacting an interface at one end, in a manner to attenuate escape of gas from the containers between the closures and the interface has a supporting framework and at least one insert within the framework, the insert engaging the framework and presenting a surface having a plurality of indentions in the shape of the liquid-filled containers, each indention conforming to shape of one of the containers in a manner that a container placed in the indention is supported with an axis of symmetry of the container at an acute angle with horizontal and with closure end down, such that liquid in the container surrounds the closure and interface, so gas will not escape between the closure and the interface.

  • Publication number: 20110098058
    Abstract: A tracking device has an on-board power source, a central processing unit, a cellular telephony transmitter and receiver, a speaker and a microphone, a bus system interconnecting electronic elements, and software or firmware executing at least periodically from a machine-readable physical medium providing a range of functions for the device. The device maintains a sleep mode until activated by an internal timing function, once activated turns on the receiver and listens for radio signals, finding particular signals, consults memory associations with one or more of those signals, and determines to activate transmission only under certain preprogrammed conditions depended on signals found and identified.
