  • Publication number: 20240099375
    Abstract: The present disclosure relates to aerosol delivery devices, methods of forming such devices, and elements of such devices. In some embodiments, the present disclosure provides a heating member that can be formed of a heating element conformed to a heater substrate configured as a truncated cone (or similar shape) having a first end of a first size and a second end of greater size. In some embodiments, the disclosure provides methods of forming an aerosol delivery device, which can include providing a shell, providing a heating member formed of a heating element conformed to a substrate, configuring the heating member as a truncated cone (or similar shape) having a first end of a first size and a second end of greater size, and inserting the heating member within the shell.

  • Patent number: 7792150
    Abstract: Methods, systems, and computer program products for providing transcoder-free operation in a media gateway are disclosed. In one method, first and second lists of media encoding rates and corresponding indices used by first and second media endpoints of a media stream connection are received. It is determined whether transcoder-free operation is possible for the media stream connection based on the first and second lists. In response to determining that transcoder-free operation is possible for the media stream connection, a transcoder-free connection is established in the media gateway between the first and second endpoints using a single digital signal processor to monitor and map between indices and encoding rates used by the first and second endpoints during the media stream connection.

  • Patent number: 7477623
    Abstract: Methods, systems, and computer program products for caching and reusing bearer channels for voice over packet sessions involving wireless entities are disclosed. According to one method, a setup request message is received for a voice over packet session involving a wireless entity. In response to the setup request message, a bearer channel is established using bearer channel setup signaling. When the first session is released, the bearer channel is cached for a predetermined time period. A second setup request message is received. The second setup request message involves the first and second nodes and a wireless entity. In response to the second setup request message, the cached bearer channel is re-used for the second session.

  • Patent number: 7319341
    Abstract: The present invention is a novel method and computer program product which utilizes an interface capacitor formed by the metal of the probe tip, a dielectric layer, such as an oxide, formed by a contaminant on a solder bump and the metal of the solder bump. The interface capacitor forms a capacitive divider with the inherent capacitances of the automatic test equipment and the device under test (DUT). The voltage characteristics of the capacitive divider are used to drive voltage signals across the interface capacitor to test the DUT. In either direction (i.e. from the automatic test equipment to the DUT or vice versa), by altering the voltage output high amplitude of the driver and/or the voltage input high amplitude of the load, the DUT is validly tested through the interface capacitor. Thus, even if all I/O bumps have an oxide layer, the device may still be validly tested.
