Title: Biostable polyurethane and medical article therefrom
Inventor: MANN GREGORY J
IPC: C08G18/72
Filed: 1994-04-19
Abstract: Abstract of the Disclosure A melt processable segmented polyurethane with a hard segment composition in therange about 20 percent to about 40 percent. The polyurethane of the invention has a soft segment that includes an aliphatic diol having a molecular weight greater than about 1000. The aliphatic diol used in the invention is substantially free of ester and ether linkages, thus substantially eliminating potential sites for biodegradation and formation of potentially harmful low molecular weight extractable fragments. As a result of the low percentage hard segment, the polyurethane of the invention is inherently soft without the use of low molecular weight plasticizers and is well suited for applications requiring prolonged exposure to body fluids and enzymes. Such applications include pacemaker lead insulation, indwelling catheters, drainage devices and the like.

Patent CA-2159300-A1 (CA)
Title: Digital Data Sequence Pattern Filtering
Inventor: ANDERSON BRADLEY T
IPC: H04L7/04
Filed: 1995-09-27
Abstract: To recognize a specific pattern of bits anywhere within a high speed bit stream of data, the serially-received bytes of the bit stream are first converted to parallel or simultaneously-presented, eight-bit bytes. Received bytes are used as the addresses of two SRAMs. A byte of the desired pattern is recognized by having that byte address a memory location of one of the SRAMs in which a binary "1 " has been stored at the bit location within that memory location that corresponds to the received byte's position within the expected bit pattern.  The other seven bit locations within that memory byte have binary "Os" stored in them.      The outputs from the two SRAMs are gated to look for a sequence of two successive bytes of the expected pattern. A binary "1", signifying recognition of receipt of two successive bytes, is clocked into one of a plurality of shift registers. The length of each shift register represents the opposite of the position, within the expected sequence pattern, of the two successive bytes. The outputs of the shift registers are all connected to inputs of an AND-gate, the output of which indicates a match with the respected sequence pattern. As each successive pair of received bytes is clocked into the address registers of the SRAMS, the shift registers are clocked to advance their stored bits by one stage.

Title: A device and a method for localizing leakages in conduit networks
Inventor: LANGE GOESTA
IPC: G01H11/08
Filed: 1994-03-29
Abstract: Device and method for locating leaks in pipelines, overhearing even weak sounds, from leaking fluid especially in pipelines made of material with limited sound conductivity such as plastic. The device includes a first thin diaphragm (1) with one side (3) in contact with the fluid, whereby vibrations are transferred from the fluid to a second diaphragm (5) joined to the opposite side of the first diaphragm (1).   The second diaphragm (5) is made of a preferably sound-sensitive piezo-electrical plastic-foil, the diaphragms being able to co-vibrate with frequencies from one to a few thousand Hertz. The first diaphragm (1) protects against the inner pressure in the liquid lint and moderates any sympathetic vibration.   The low-frequency A.C. that is generated by the vibration in the second diaphragm (5) is amplified and transposed to a range of frequencies that is audible for the human ear.
