Patent number: 8228925Abstract: An interactive voice response system (102) includes a protocol interface (134) that is adapted to communicate with a plurality of divergent telecommunications networks for voice communications (104, 106, 108, 110). These networks are, for example, a wireline telecommunications network, a CDMA network, a GSM network, and a voice over IP network. A controller (136) is coupled to the protocol interface to receive a plurality of common call control messages from, and to supply a plurality of common call control messages to, the protocol interface. The protocol interface converts control messages from each one of the plurality of divergent telecommunications networks into the plurality of common call control messages for the controller. The controller generates and receives the common call control messages to cause a prompt and collect interaction with a caller that is using a device that is coupled to one of the networks.Type: GrantFiled: December 14, 2005Date of Patent: July 24, 2012Assignee: Alcatel LucentInventors: Yigang Cai, Sheng Chen, Xiang Yang Li, Peng Wang, Ying Wang, Rui Yun Wu, Jay Z.

Patent number: 7680655Abstract: A method and apparatus are provided for determining the quality of a speech transmission, including temporal clipping, delay and jitter, using a carefully constructed test signal (300) and digital signal processing techniques. The test signal that is to be transmitted through a speech transmission system (100) is created (700). Then the test signal is transmitted through the speech transmission system such that the speech transmission system creates an output signal that corresponds to the input signal, as modified by the speech transmission system (702). The test signal includes multiple segments (500) of speech signals interleaved with periods of silence. The periods of silence vary in duration according to a predefined pattern. Each segment of speech signals includes multiple predefined speech samples or symbols (400, 402, 404, 406, 408, 410, 412, 414) interleaved with a plurality of silence gaps. The speech samples have a common period of duration, but the silence gaps do not.Type: GrantFiled: May 20, 2005Date of Patent: March 16, 2010Assignee: Alcatel-Lucent USA Inc.Inventors: Ronald Jay Canniff, Michael R.

Patent number: 7487677Abstract: Apparatus and methods for employing electrical properties of water to indicate the level of filtered water in a filtered water container. The container is fitted with a hopper that holds unfiltered water. The hopper is fitted at its base with a removable and replaceable filter cartridge. Water is filtered by draining through the filter medium contained in the filter cartridge into the lower portion of the container. The water level in the filtered water container is monitored by means of one or more water level detector strips in the hopper or in the lower portion of the filtered water container. The detector strips are in electrical communication with a detection circuit and a control unit. The control unit uses the detection strips to monitor water level and uses such data to track filtered water consumption and to determine when the filter cartridge should be replaced.Type: GrantFiled: December 22, 2004Date of Patent: February 10, 2009Assignee: Fook Tin Technologies Ltd.Inventors: John Y.

Patent number: 7328820Abstract: A vented closure for a liquid container which will not freely pour includes a cap hinged at one side and movable between open and closed positions relative to a base collar. In an open position, a primary fluid passageway extends through a shaped mouthpiece which is elongated and tapered to conform to a user's mouth. One or more air vents of small size are located in a protected floor of the base collar at positions spaced within predetermined ranges of offsets from the dispensing opening so as to convey liquid into contact with the air vents in a manner to self-seal the air vents by surface tension of the liquid until an unbalance force is present. The cap and collar mate along an offset diagonal edge, and a grip area for the user's thumb or finger is offset from a center line. The offsets cause the cap to flip open with additional clearance and without obstructing a user's nose.Type: GrantFiled: October 27, 2005Date of Patent: February 12, 2008Inventor: John L. Young

Patent number: 7315512Abstract: The invention discloses a method for implementing signaling link redundancy in IP networks. Two ASPs are created for the same AS in the host at the IP network side, and all user adaptation protocols share ASPSM and ASPTM messages so that the states of the two ASPs can become active and inactive respectively, thus to implement two signaling links for serving the same traffic. When switch is initiated, SCTP association can be closed by using “graceful close”, and the SCTP itself will make sure to send out all the data remaining in its buffer and its higher-layer applications will also send subsequent data in order after learning the remaining data are all sent out, thus sequential delivery for the data can be guaranteed. This method can avoid data loss and disorder, and the speed for switch can be ensured because the backup link will be notified immediately after the data on the primary link are sent out.Type: GrantFiled: November 28, 2002Date of Patent: January 1, 2008Assignee: ZTE CorporationInventor: Min Xi

Patent number: 7275665Abstract: A vented closure for a liquid container which will not freely pour includes a cap movable between open and closed positions relative to a base collar. The movable cap can be slidable to form a push-pull type closure, or can be rotatable to form a flip-type closure. In an open position, a primary fluid passageway extends through the closure to one or more dispensing opening. One or more air vents of small size are located in the base collar at positions spaced within predetermined ranges of offsets from the dispensing openings. A divider or barrier is located to create a secondary fluid passageway to convey liquid directly into contact with the air vents which can self-seal by surface tension of the liquid and to convey air bubbles through the liquid when the container is tilted. Overlapping portions of the movable cap can protect the vent apertures and/or the dispensing aperture structure.Type: GrantFiled: June 16, 2004Date of Patent: October 2, 2007Inventor: John L. Young

Patent number: 7277482Abstract: A method and apparatus for adaptive signal compression of unknown signals uses minimal power and bandwidth to transmit data. The method provides adaptive signal compression with minimal loss and distortion by extracting only information of interest and recreating the full signal. The method uses a single resolution filter bank for channelizing a data stream for transmission. The method removes unwanted or unneeded information before transmitting the data by using fidelity and user controls and detection capabilities. The method provides significant signal compression where signals are sparse in frequency, time, or both and does not rely on a priori knowledge of the signal. After transmission, the system generates a signal using the data received as well as filling in the non-transmitted portions of the signal by manipulating the transmitted data. The system then formats the signal into the original data stream using a reconstruction filter bank.Type: GrantFiled: May 29, 2002Date of Patent: October 2, 2007Assignee: General Dynamics C4 Systems, Inc.Inventors: Kenneth Solomon Wreschner, Eric Jay Clelland, Keith Petticrew, Robert Lee Trapp, Chad Rhamy

Patent number: 7231086Abstract: A knowledge-based hierarchical method for detecting regions of interests (ROIs) uses prior knowledge of the targets and the image resolution in detecting ROIs. The result produces ROIs that contain only one target that is completely enclosed within the ROI. The detected ROI can conform to the shape of the target even if the target is of irregular shape. Furthermore, the method works well with images that contain connected targets or targets broken into pieces. The method is not sensitive to contrast levels and is robust to noise. Thus, this method effectively detects ROIs in common real world imagery that has a low resolution without costly processing while providing fast and robust results.Type: GrantFiled: May 9, 2002Date of Patent: June 12, 2007Assignee: General Dynamics C4 Systems, Inc.Inventors: Glen P. Abousleman, Huibao Lin, Jennie Si
