Title: Method for amplifying nucleic acid sequences by translocation using chimeric primers
Inventor: CLEUZIAT PHILIPPE
IPC: C12Q1/6844
Filed: 1996-07-24
Granted: 2011-05-10
Abstract: A target nucleic acid sequence (12) may be amplified in the presence of an enzymatic system including DNA polymerase, strand translocation and RNAse H activities by using a chimeric primer (A1, A2) that includes, in the 5' to 3' direction, an RNA-type segment capable of hybridising with a 3'-terminal segment of the target and a DNA-type segment capable of hybridising with a segment adjacent to said 3'-terminal segment of the target, and a DNA- or RNA-type primer B1 capable of hybridising with said 3'-terminal segment of the target. A cyclic amplification is achieved that may be implemented isothermally on the basis of either a DNA or an RNA target even when the terminals are not defined.

Title: Method and apparatus for cough sound analysis
Inventor: AFSHARI ALIAKBAR
IPC: A61B7/00
Filed: 1999-04-23
Granted: 2009-12-22
Abstract: A fast, simple, and reliable method and apparatus for recording cough sounds for diagnosing pulmonary disorders and diseases is provided. This method uses signal analysis techniques to extract quantitative information from recorded cough sound pressure waves. The generated data can be used to diagnose pulmonary disorders and diseases as well as track the effectiveness of treatment regimens over time. The method can also be used to quickly and reliably screen individuals at risk of pulmonary disorders and diseases. The discovery of early stages of pulmonary disorders or diseases may allow earlier treatment and/or environmental modification to reduce the risk or irreversible injury to pulmonary function. The system, which is a simple, non- invasive system that can quickly and easily be administered with minimum technician and patient training, uses a mouthpiece, a tube having a distal end and a proximal end, a flexible tubing having a distal end and a proximal end, and a microphone; wherein the mouthpiece is attached to the proximal end of the tube, wherein the distal end of the tube is attached to the proximal end of the flexible tube, wherein the microphone is attached to the tube between its distal and proximal ends such that the microphone can record sound pressure waves within the system without distorting the pressure waves, and wherein the flexible tubing is sufficiently long so there are essentially no reflected sound pressure waves which interfere with the recording of the sound pressure waves at the microphone. Preferably, the system also includes a computer system to assist in recording and analyzing the sound pressure waves. A calculated cough sound index (CSI) can be used in diagnostic applications.

Abstract: A method of announcing to a calling party in an originating system that a called party in a serving system is not available. The originating system sends a message, with a parameter indicating that it is capable of generating announcements, to the serving system. The latter then determines that the called party is not available. Next, the serving system sends a message, wit h a parameter requesting the originating system to provide an announcement to the calling party, to the originating system. This message may include a Preferred Language parameter and an Allow Transfer to Number parameter if the called party subscribes to services requiring service logic support. Any trunk seized from the originating system to the serving system is then released. Finally, the originating system sends the announcement to the calling party announcing that the called party is not available, the announcement being made in the preferred language if indicated.
