Title: Inflatable mattress with improved border support wall
Inventor: SHOENHAIR JOHN J
IPC: A47C27/10
Filed: 1996-09-19
Abstract: A mattress (10) with an inflatable bladder (12) and an outer border wall (14) to support the outer edges of the bladder (12). The present invention employs foam block border walls that include foam border elements (20, 22, 24, 26) with either an upper (38) or an upper (38) and a lower surface (40) sculpted to present convolutions preferably having generally sinusoidal shapes in vertical cross section. The convolutions allow for a sensation of softness when being deformed, and allow for ventilation of the inner surface, while at the same time, the foam element can be made of a single piece of foam that is of sufficient stiffness to support the outer perimeter surface of the bladder (12) within the mattress (10).
Patent CA-2233199-A1 (CA)
Title: Container
Inventor: LOFTUS STEPHEN CLIVE
IPC: B65D43/16
Filed: 1998-03-26
Abstract: A container in which the lid 16 is attached to the body of the container by a hinge arrangement. When the hinge arrangement is assembled, knuckles 30 on the lid 16 are interleaved with knuckles 20 formed along the upper edge of the container walls. Each of the knuckles 20, 30 has an elongate bore formed to receive a single hinge pin along the common line 22, 36. When the lid 16 is closed, tab 34 projects through the socket 24 into the interior of the knuckle 20, thereby preventing the hinge being pulled apart.
Patent CA-2234013-A1 (CA)
Title: In-fiber two-stage amplifier providing wdm signal conditioning
Inventor: LAUZON JOCELYN
IPC: H04B10/294
Filed: 1998-04-06
Abstract: The amplifier is a two-stage amplifier in which dispersion compensation and WDM channel equalization are carried out using a plurality of in-waveguide Bragg gratings placed between the two stages. The first stage has a gain able to raise the intensity of WDM optical communications signals to a high enough level that after dispersion compensation and equalization, the signals fed into the second stage nearly or substantially saturate the second stage amplifier. The noise figure signal-to-noise ratio is thereby of good quality since there are no significant losses at the signal input of the signal into the optical amplifier. Erbium-doped optically pumped fiber amplifiers are used for the two stages. An add/drop filter can be appended to the end of the conditioning Bragg gratings. Residual optical signal from the fiber Bragg grating may be used to optically pump another amplifier for amplifying longer wavelength optical signals.

IPC: A61M60/865
Filed: 1998-05-27
Abstract: When both the IABP and the PCPS are used, they exhibit an excellent circulation assisting effect.          In this case, however, sequela such as hypoxic encephalopathy may well occur after the heart failure is remedied.  The invention provides an intraaortic balloon catheter capable of preventing such sequela.          The balloon catheter of the invention comprises a catheter main body part of which is to be inserted into an aorta, and a balloon section formed on an outer peripheral portion of the catheter main body, to be inserted into the aorta together with the main body, and to be expandible and contractible in the aorta under the control of the IABP.  An end portion of the catheter main body functions as an introductory portion of the catheter, and has a blood feed hole formed therein for introducing, into an artery such as the aortic arch, arterial blood of high oxygen concentration fed from a circulation assisting unit such as the PCPS.  The catheter main body has a blood feed passage communicating, at one end thereof, with the blood feed hole which leads to the aorta, and communicating, at the other end thereof, with a PCPS connection port.          The blood feed passage is used for sending the arterial blood of high oxygen concentration to the aorta via the blood feed hole.

IPC: G01N21/64
Filed: 1998-10-09
Abstract: In the measurement system for detecting optical signals of microassays, the signal- generating test objects 5 are arranged on an investigation surface of a planar carrier 4. The planar carrier 4 is, in particular, a microtitre plate for biological objects. In principle, the measurement system comprises an optical imaging arrangement which reduces the size of the test objects 4 to be measured in such a way that all the objects are imaged completely on a two-dimensional, photosensitive image sensor 6. For imaging, a high-resolution glass-fibre taper element 1 having a large-area 2 and a small-area end 3 is used in this case, whose end surfaces 2, 3 are selected such that the large-area end surface 2 corresponds at least to the investigation surface of the carrier 4 and the small-area end surface 3 corresponds to the size of the image sensor 6, the ratio of the end surfaces 2, 3 producing the scale of reduction of the optical imaging arrangement in order to image the investigation surface of the carrier 4 completely onto the image sensor 6.
