Patent CA-2144430-A1 (CA)
Inventor: YAMAGUCHI SEIJI
IPC: G01S17/36
Filed: 1994-07-12
Abstract: A phase difference measuring apparatus of the present invention obtains a first receive signal by transmitting and receiving a to-be-measured material in a reference state and a second receive signal by transmitting and receiving a signal wave to and from that material in a measured state.  The apparatus finds a reference phase difference .THETA.1 from the transmit wave and first receive signal and an apparent phase difference .THETA.2' from the transmit wave and second receive signal.          The apparatus adds the apparent phase difference .THETA.2' to a product of the number of rotations, n, the apparent phase difference .THETA.2' passes through a given reference point and an angle of 360° to find a true phase difference .THETA.2.  The apparatus varies the number of rotations, n, to n+1 when the apparent phase difference .THETA.2', while being increased, passes through the reference point and that number of rotations, n, to n=n-1 when the apparent phase difference .THETA.2', while being decreased, passes through the reference point.

Title: Assay method to rule out rupture of membranes in women at risk for imminent delivery
Inventor: LEAVITT JOHN C
IPC: G01N33/53
Filed: 1994-01-21
Abstract: The present invention provides an assay that distinguishes those patients with imminent delivery with intact membranes from those in whom the membranes have ruptured. The method comprises obtaining a cervicovaginal secretion sample from a pregnant patient determined to be as at risk for imminent delivery by detection of a biochemical marker for imminent delivery in a cervicovaginal secretion sample from the patient and determining the level of IGFBP-1 in the sample. If the level of IGFBP-1 is elevated, the patient has rupture of membranes. If IGFBP-1 is not present, the patient has intact membranes. In a preferred embodiment, the method comprises obtaining a cericovaginal secretion sample from a pregnant patient after about week 20 of gestation and determining the level of fetal fibronectin and IGFBP-1 in the sample. The presence of an elevated fibronectin level in the sample indicates an increased risk of imminent delivery. If the level of IGFBP-l is elevated, the patient had rupture of membranes. If IGFBP-1 is not present, the patient has intact membranes. If IGFBP-I is not present, the IGFBP-I assay is preferably repeated. In those patients with an increased level of IGFBP-I, the test indicates that delivery cannot be delayed.

Title: Electroluminescent edge connect-composite lamp/strip and method of making the same
Inventor: DAIGLE LYMAN R
IPC: H05B33/12
Filed: 1995-08-21
Abstract: The method and structure for providing a pair of electrical contact terminals on the back side of an electroluminescent (EL) lamp. The EL lamp has a first conductive layer, a layer of EL material, a first insulating layer, a second conductive layer, a second insulating layer and a film of conductive material, all disposed on a transparent substrate, respectively. The film of conductive material extends around the second insulating layer to come in electrical contact with the first conductive layer. This allows an electrical contact terminal to be established on the film of conductive material, rather than directly on the first conductive layer. The other electrical contact terminal is positioned on the second conductive layer. The second insulating layer serves to electrically separate the two contact terminals.

Abstract: La présente invention concerne les bibliothèques structurées d'antigènes de synthèse ou "SSAL" (Structured Synthetic Antigen Libraries) composées de peptides synthétisés simultanément en une seule synthèse peptidique. La différence entre la bibliothèque "structurée" et les anciennes bibliothèques dites "bibliothèques aléatoires de peptides" est que désormais l'ordre ou la structure interne de l'antigène de synthèse est constitué par des résidus d'acides aminés invariants qui définissent la séquence squelette de l'antigène de synthèse. Les acides aminés spécifiques et leur fréquence d'occurrence à un locus de variant dans une séquence peptidique alignée sont définis par rapport aux séquences primaires de plusieurs variants constituant l'alignement utilisé pour la réalisation de la bibliothèque de peptides. Est également décrit un procédé d'élaboration d'un agent diagnostique, d'un vaccin ou d'un agent thérapeutique à large spectre pour un agent infectieux en mutation. L'invention concerne également l'utilisation des SSAL pour des procédés de diagnostics, des kits, des procédés de vaccination, des compositions vaccinales et des compositions pharmaceutiques. Ces bibliothèques, qui sont élaborées à partir de domaines variables des protéines, permettent, à partir de telles protéines, la réalisation de meilleurs vaccins, de meilleurs agents diagnostiques et de meilleurs moyens thérapeutiques adaptés aux agents infectieux notamment.
