Abstract: The present invention relates to a method for synchronization of real-time signals between core network and air interface in a UMTS Terrestrial Radio Access Network (UTRAN). The synchronization of the signals is needed to make a feasible connection between user equipment and a core network. This is achieved by using the timing knowledge from the protocols that are to be synchronized, and recalculating synchronization parameters for both uplink and downlink transmission. By using frame numbers instead of time of arrivals of frames, the present invention gives better control of timing and avoids long delays, and handles the problems with time alignments.

Abstract: If TDM connections are through-connected from the originating TDM network to the target TDM network via a data network in the form of backbone, e.g. VoIP, the switchover between the TDM network and the data network takes place via media gateways. As is the case with connections exclusively between TDM, the coding algorithms of the A face and the B face have to be identical. In TDM networks, coding is done according to A Law and mu Law. When switching from an A Law network to a mu Law network, the coding specifications have to be converted. In order to carry out a conversion in a TDM environment, at the switchover point the mu Law face has to convert to A Law. The same applies to VoIP. The invention relates to the integration of this switchover conversion rule in the codec negotiation procedure so that in principle a mu Law A face offers mu Law and, alternatively, A-Law to the B face; a mu Law B face accepts mu Law whereas an A-Law B face acknowledges A-Law. Furthermore, 64 kBit/s unrestricted preferred connections are considered in fall back mode, wherefore an additional logic is integrated into the codec modification procedure by means of which in principle mu Law and, as an alternative, A-Law are offered to the B face in addition to the transparent CODEC or instead of offering a mu Law A face to the TMR only. The B face first accepts the transparent CODEC on the basis of the list or the TMR '64 kBit/s unrestricted preferred'. When receiving the TMU, the B face selects the Codec to satisfy the code conversion rule.

Abstract: In the present invention, a catheter comprises a resiliently biased projection and a detector which generates a signal which varies as a function of radial displacement of the resiliently biased projection relative to the longitudinal axis of the catheter. In a preferred example, the catheter comprises a resiliently biased projection comprising one plate of a variable capacitor, wherein the capacitance varies as a function of radial displacement of the resiliently biased projection. Thus, a signal processing system electrically coupled to the variable capacitor plate may be adapted to detect changes in the capacitance of the variable capacitor. This affords a method of studying the physiology and/or morphology of a vessel wall by detecting capacitance variations between capacitor plates inserted into the vascular tissue. The present invention allows dimensional characteristics of the vascular tissue to be determined. For example, the cross-section of a vascular lumen can be measured by measuring the capacitance between the plates of the variable capacitor and relating this to the distance between the plates. If the position of one of the plates in the lumen is known, for example, being positioned against one wall of the vessel, the resiliently biased projection, comprising the other plate of the variable capacitor, can bias itself against the opposing wall. The measured capacitance is directly proportional to the distance between the plates.

Abstract: 対象の少なくとも２つの部分に可撓性の細長い要素を導入する装置（２）を開示している。好ましい実施形態では、装置は、近位端および遠位端と、可撓性の細長い要素を、その近位端が対象を貫通するのに十分な力で装置（２）の遠位端から出ることができるように、装置（２）の遠位端に向かって長手方向に前進させる前進ユニット（３００）と、を備える。装置はまた、その遠位端に、装置（２）の遠位端から出る可撓性の細長い要素の一部をループ形状にする湾曲ダイ（２０４）と、装置の遠位端に戻るループ状の可撓性の細長い要素を収容する湾曲ガイドと、を備える。本発明のさらなる特徴として、ループ状の可撓性の細長い要素が可撓性の細長い要素の残りから分離するのを可能にする切断機構（２０６）が設けられる。また、本発明のさらなる特徴では、切断機構（２０６）は、ループ状の可撓性の細長い要素の後端が、縫合されている対象に向って遠位方向に押し曲げられるように変形させるように構成される。
