Title: A method of controlling connections in a telecommunication system
Inventor: NOVAK LARS
IPC: H04Q3/545
Filed: 1996-04-23
Abstract: User terminals (14-15) are connected to a telecommunication system. The telecommunication system comprises a control system (3) for the control, such as set-up, release and modification, of connections between the user terminals. A large portion of functions are common for control of dynamical as well as semi-permanent connections. Control of a connection can be initiated from any of the user terminals to which the connection relates, or from other user terminals. Control data for the connections can be stored in different types of storage resources in the control system, said different types of storage resources (20, 21, 24) having different degrees of reliability.

Abstract: A method of quantitative analysis of an enzyme linked immuno assay comprising the steps of forming an antigen - antibody complex between an antigen present in a sample to be tested and an enzyme labelled antibody and then adding a substrate composition which can be converted into a differently coloured product composition by the catalytic action of the enzyme. The quantification is achieved by measuring the time elapsed from addition of the substrate composition until the colour change occurs. The colour change is sudden and discernable by eye. The measured time is then compared against a predetermined reference standard to determine the amount of antigen present in the sample.

Abstract: A system for intrauterine detection of one or more biological substances, such as meconium or blood, is disclosed. The presence in amniotic fluid of such biological substances indicates an abnormal condition which justifies intervention on the part of a medical practitioner supervising the labor and delivery. A flexible cable (14) which can be inserted into the uterus is provided which includes at least two lumens. The first lumen is used to draw amniotic fluid through a port (16) in the lumen and into an observation chamber outside of the uterus and at the end of the first lumen. The fluid is visually observed by a medical practitioner for the presence of a biological substance or the biological substance can be detected by any one of several described instruments. It is preferred that if an instrument is used to detect the biological substance that a transparent visual observation chamber also be included to allow visual detection also. The apparatus allows stained fluid to be withdrawn from, and clean fluid to be infused into, the uterus in order to reduce the concentration of, and the effect of, the undesirable biological substance in the uterus.

Abstract: Symbol 102 that is spread with the only short spreading code and inserted in synchronism with a long spreading code is specified by detecting the correlation with only the short spreading code. Next, another short spreading code indicative of a timing of reverse and forward link switching is specified, where the short spreading code is multiplexed at the same position as that of the detected symbol. The detection of the symbols spread with only these spreading codes enables to acquire synchronization of the long spreading code, synchronization of switching of reverse and forward links, and synchronization of a transmission frame. It is thereby possible to reduce synchronization acquisition time for the long spreading and an easy planning of base station locations without decreasing the frequency utilization efficiency.
