Patent number: 6094576Abstract: The present invention relates to a connection establishment method and a radio system. When a base station (11) detects a preamble (20) from a subscriber terminal equipment (13), the power adjustment of a closed loop is started for controlling the transmission power of the subscriber terminal equipment (13). Signals (15) of the base station (11) and the subscriber terminal equipment (13) are synchronized and the subscriber terminal equipment (13) sends a randomly selected identifier. The identifier determines a transit channel to which the subscriber terminal equipment (13) suggests to move. The base station (11) may change the suggested transit channel and echo the identifier back to the subscriber terminal equipment (13), and the base station (11) and the subscriber terminal equipment (13) communicate on the transit channel from which they move to a traffic channel. The inventive method accelerates connection establishment.Type: GrantFiled: January 26, 1998Date of Patent: July 25, 2000Assignee: Nokia Telecommunications OyInventors: Hannu Hakkinen, Jere Keurulainen, Zhi-Chun Honkasalo, Anu Virtanen, Mikko Rinne

Patent number: 6090913Abstract: A process employs amidine or amidine base and a metal compound in the presence of an alcohol or water to transesterify, or saponify esters or amides. Since the process employs relatively mild conditions, it is especially suitable for the production of optically active substances and biomolecules, e.g. peptides, amino acids and nucleic acids which are sensitive to elevated temperatures, extreme pH values and/or long reaction times since these compounds are easily racemised or denatured. The conditions additionally find use in solid phase systems. When amino acid or peptide esters are saponified, the splitting is brought about with lithium hydroxide alone under mild conditions. The use of an amidine base, more particularly DBU or DBN, in combination with the metal salt additionally accelerates the reaction so strongly that even sensitive acid derivatives can be reacted under mild conditions.Type: GrantFiled: March 27, 1997Date of Patent: July 18, 2000Assignee: Degussa-Huls AktiengesellschaftInventors: Karlheinz Drauz, Thomas Muller, Matthias Kottenhahn, Dieter Seebach, Adrian Thaler

Patent number: 6090047Abstract: A novel method for estimating the end-systolic pressure-volume relationship (ESPVR) is presented. The method provides for accurate estimation of the ESPVR from a single beat of the cardiac cycle. The method is based on normalized human time varying elastance curves [E.sub.N (t.sub.N)]. The ESPVR is estimated from one beat using PV data measured at normalized time t.sub.N and end-systole (t.sub.max) to predict intercept: ##EQU1## and slope: E.sub.max(SB) =P(t.sub.max)/[V(t.sub.max)-V.sub.0(SB) ]. The present invention provides a method for ESPVR estimation which is non-invasive and particularly applicable for bedside applications.Type: GrantFiled: November 3, 1997Date of Patent: July 18, 2000Assignee: Johns Hopkins University, School of MedicineInventors: David A. Kass, Hideaki Senzaki, Chen-Huan Chen

Patent number: 6074141Abstract: A scroll member has a scroll wall having an axial end having a transverse surface on which a groove 20 is cut along the spiral direction of the scroll wall, to which groove a seal member contacting a facing scroll member is received. The scroll wall has a radially inner portion having a width larger than the width of the remaining part of the scroll wall. At the radially inner portion, the groove is also widened. When molding the scroll member, a recess deeper than the depth of the groove to be machined is created. The groove is obtained by machining the scroll member as molded by a milling tool. The widened portion of the groove is formed by moving a milling tool along a closed trajectory, so that the recess is left un-machined.Type: GrantFiled: August 2, 1996Date of Patent: June 13, 2000Assignees: Nippondenso Co., Ltd., Kabushiki Kaisha Toyoda Jidoshokki SeisakushoInventors: Kimihiro Ishikawa, Takashi Miyakawa, Yasushi Watanabe, Tetsuhiko Fukanuma, Shinya Yamamoto

Patent number: 6066780Abstract: The synthesis of lignin by plants is controlled by transformation of the plant genome with a recombinant gene construct which contains the gene specifying an enzyme critical to the synthesis of a lignin precursor, which gene may be in antisense orientation so that it is transcribed to mRNA having a sequence complementary to the equivalent mRNA transcribed from the endogenous gene thus leading to suppression of lignin synthesis. If the recombinant gene has the lignin enzyme gene in normal, or "sense" orientation, increased production of the enzyme may occur when the insert is the full length DNA but suppression may occur it only a partial sequence is employed.Type: GrantFiled: May 26, 1995Date of Patent: May 23, 2000Assignee: Zeneca LimitedInventors: Alain Michel Boudet, Dirk Gustaaf Inze, Wolfgang Walter Schuch

Patent number: 6067372Abstract: A method and apparatus for detecting abnormal regions in living tissue depicted in a digital radiograph includes identifying suspected abnormal regions depicted in the radiograph and then, for each identified suspected abnormal region, extracting multiple topographic layers of the region from the digital radiograph; determining features of the region in each of the layers; and applying inter-layer multivariate non-linear criteria to the features to determine whether the suspected abnormal region is to be classified as an abnormal region. The distribution of digital values in the digitized radiograph is modified and a probabalistic determination is made as to whether suspected abnormal regions are actually abnormal from multiple analyses.Type: GrantFiled: February 18, 1998Date of Patent: May 23, 2000Assignee: University of PittsburghInventors: David Gur, Bin Zheng, Yuan-Hsiang Chang
