Patent CA-2209457-A1 (CA)
Title: Cdma communication system and method
Inventor: DOI NOBUKAZU
IPC: H04B1/707
Filed: 1997-07-02
Abstract: In CDMA communications, a base station detects a difference between a reference phase of a spreading code and a phase of a received signal of each terminal station, and feeds a phase jump signal PJ-i representative of the phase difference back to each terminal station. After timing acquisition, the reception operation is performed using the reference phase, and a shift amount between the phase of a received signal and the reference phase is fed back to each terminal station as phase synchronization control information PC-i. Each terminal station coarsely adjusts the phase of the spreading code in accordance with the phase jump signal PJ-i, and thereafter finely adjust the phase of its transmitting signal in accordance with the phase synchronization control information PC-i. It is therefore possible to synchronize the phases of signals transmitted from terminal stations and received at the base station. Accordingly, an orthogonal code is used for spreading on reverse links.

Patent CA-2229944-A1 (CA)
Inventor: PY DANIEL
IPC: B65D41/18
Filed: 1998-02-19
Abstract: A mechanical lid or a plug interacts with an opening of a pouch or a container, as well as with a rigid ring placed inside the container opening to provide a tight seal of the opening.  The mechanical plug is snapped into the container opening such that the mechanical plug compresses both the outside of the opening and the inner face of the ring placed inside the container opening.  The radial edge of the inner face of the mechanical plug has an arch-shaped annular recess extending around the plug such that the radial edge of the plug is adapted to hug the perimeter of the container opening.  In addition, attached to the inner face of the mechanical plug are two or more legs which extend perpendicular to the inner face of the mechanical plug and engage the bottom of the rigid ring/radial groove combination.  The outside surface of the neck region of the container opening and the interior surface of the annular recess of the mechanical plug each has one or more protrusions which force the container material displaced by compression to be confined within a defined area, thereby ensuring the tightness of the seal for a prolonged period of time.  The lower surface of the mechanical plug is sloped downward in the direction of the center, to which a plunger is attached for insertion into the liquid content of the container before the mechanical plug is snapped into the container opening, thereby substantially eliminating the residual air bubbles which may otherwise remain trapped between the surface of the liquid and the lower surface of the mechanical plug, which allows airless filling of the container without the need for a vacuum condition.

Filed: 1997-02-26
Abstract: A probe inspects steam generator tubing for defects. The probe includes a transducer which generates a localized ultrasonic Lamb wave. The ultrasonic wave is transferred to the tubing by a coupling medium, such as water, that physically couples the transducer and the tubing. Defects in the tubing reflect the ultrasonic wave to the probe which detects the reflections. The results are thenused to determine the length and depth of such defects as cracks, pitting, and thinning. The localized ultrasonic wave performs and inspection sensitive enough to detect ligaments between crack segments. This allows highly accurate predictions of tubing integrity and rupture strength.

Title: Masking background fluorescence and luminescence in optical analysis of biomedical assays
Inventor: BECHEM MARTIN
IPC: G01N33/50
Filed: 1997-05-23
Abstract: In a process for the quantitative optical analysis of fluorescently labelled biological cells 5, a cell layer on a transparent support at the bottom 2 of a reaction vessel 1 is in contact with a solution 3 containing the fluorescent dye 4. The sensitivity of analytical detection can be considerably improved if to the fluorescent dye 4 already present in addition a masking dye 9, which absorbs the excitation light 6 for the fluorescent dye 4 and/or its emission light 7, is added to the solution 3 and/or if a separating layer 10 permeable to the solution and absorbing and/or reflecting the excitation light 6 or the emission light 7 is applied to the cell layer at the bottom 2. This process can also be used for improving the sensitivity in the quantitative optical analysis of a luminescent biological cell layer. The separating layer 10 must in this case be composed such that it has a high power of reflection for the luminescent light 11. Analogously, these process principles can also be used in receptor studies for the masking of the interfering background radiation in the quantitative optical analysis of fluorescently or luminescently labelled reaction components. In this case, a receptor layer 12 at the bottom 2 of a reaction vessel 1 is in contact with a solution (supernatant 3) in which a fluorescent or luminescent ligand 13 is dissolved. The sensitivity and accuracy of the analytical detection can be considerably improved here if a masking dye 9 which absorbs the excitation light 6 for the fluorescent dye and/or its emission light or (in the case of luminescent ligands) the luminescent light is added to the supernatant 3. Instead of the masking dye in the solution 3 or optionally as an additional measure, a separating layer 10 permeable to the solution 3 and absorbing and/or reflecting the excitation light 6 and/or the emission light or the luminescent light can be applied to the cell or receptor layer 12 at the bottom 2.
