IPC: A61K45/00
Filed: 1993-12-21

Patent CA-2159230-A1 (CA)
Inventor: HORST GARY E
IPC: H02K5/24
Filed: 1995-09-27
Abstract: Apparatus (10) for controlling the current profile (P2) in a single or polyphase SRM (M) during the active portion of a phase. Switches (S1, S2) are closed during an active portion of a phase to direct current flow into a winding (W).  A Hall effect sensor (14) and other sensors are used to sense various operating parameters of the SRM.  A PWM signal generator (16), or microprocessor (20) is responsive to the sensor inputs to provide PWM operating signals (G2) to at least one of the switches to control current flow to the winding.  The operating signals modulate the switch(es) for switch operation to be controlled as a function of the signal characteristics of the operating signals.          This allows the current supply to the winding to be in accordance with the current profile.  According to the profile, current flow is initially rapidly increased from zero to a peak value (Ip ') when the phase becomes active.  The current is then allowed to decrease from this peak to a second and lesser value (Ip) by the time the phase becomes inactive.  Current decays from this second value to zero when the phase becomes inactive.  The transition in the current profile which occurs when the phase switches from active to inactive is no longer an abrupt transition, but is rather a more moderate one.  This smoother transition reduces the amount of ringing in the motor, which normally occurs when current flow into the winding ceases, thereby to reduce motor noise.

Patent CA-2159499-A1 (CA)
Title: Biologically active polypeptide fusion dimers
Inventor: THOMASON ARLEN R
IPC: C07K19/00
Filed: 1994-03-31
Abstract: The present invention provides a biologically active multimeric polypeptide molecule in which two or more monomeric subunits are linked together as a single polypeptide ("fusion multimer"). These fusion multimers are more easily and rapidly refolded than unfused multimers, because the reactions necessary to generate the biologically active multimeric form of the polypeptide proceed with first order, rather than second or higher order, reaction kinetics. Fusion multimers also eliminate the simultaneous formation of undesired polypeptide by-products during refolding. The fusion multimers of the present invention specifically include PDGF fusion dimers.

Title: Method for assuring data integrity during a repeater
Inventor: CHRISTIAN PAUL R
IPC: H04L1/00
Filed: 1994-04-04
Abstract: In a paging system (100) that comprises a system controller (102), an active repeater (103, 105, 107), and a backup repeater (104, 106, 108), data integrity during a repeater transition (208) is assured in the following manner. As each repeater (103-108) receives a stream (200, 300) of paging information from the system controller (102), the repeaters (103-108) store it. When the repeater transition (208) occurs, the backup repeater (104, 106, 108) determines the paging messages (202-206 or 302) that were not transmitted during the repeater transition (208) based on the most recently stored stream (200, 300) of paging information. Subsequently, the backup repeater (104, 106, 108) transmits (402) a paging failure message to the system controller (102) indicating the paging messages (202-206 or 302) that were not transmitted. Upon receiving this, the system controller (102) commands (403) the backup repeater (104, 106, 108) to retransmit the paging messages (202-206 or 302) that were not transmitted during the repeater transition (208).

Title: Echo cancelling system suitable for voice conference
Inventor: HASEGAWA ATSUSHI
IPC: H04M1/60
Filed: 1995-11-09
Abstract: An echo cancelling system has two echo cancellers for cancelling a channel echo and a room echo, respectively. In order to obviate echo estimation errors, the echo canceller at the channel side performs estimation only when an input signal from a channel is absent and a microphone input signal is present. The echo canceller at the room or acoustic side executes estimation only when a microphone input signal i s absent and an input signal from the channel is present. A necessary amount of suppression is applied to either the receipt side or the transmission side until the echo canceller estimates an echo, so that a howling margin is guaranteed.

Title: Method and apparatus for biological sequence comparison
Inventor: MARR THOMAS G
IPC: G16B30/10
Filed: 1996-05-30
Abstract: A method and apparatus for comparing biological sequences from a known source of sequences, with a subject (query) sequence. The apparatus takes as input a set of target similarity levels (such as evolutionary distances given in special units called PAM), and finds all fragments of known sequences that are similar to the subject sequence (or fragment thereof) at each target similarity level, and are long enough to be statistically significant. It examines all possible fragments of all sizes, yet can be implemented very economically. The invention device effectively and efficiently filters out most of the noise and artifacts (false positives and negatives) namely fragments from the known sequences that are too short, or have a lower average similarity to the subject sequence (or fragment thereof) than is required by each target similarity level. The subject sequence is then compared only to the remaining known sequences to find the best matches. The filtering member divides the subject sequence into overlapping blocks, each block being sufficiently large to contain an alignment of a certain minimum length from a known sequence. For each block, the filter member compares the block with every possible short fragment in the source of known sequences and determines a best match for each comparison. The determined set of short fragment best matches for the block provide and upper threshold on alignment values. Regions of a certain length from the known sequences that have a mean alignment value upper bound (threshold) greater than a target unit score (relative entropy) are concatenated to form a union. The current block is compared to the union and provides an indication of best local alignment with the subject sequence. If the best local alignment has a match score of greater than or equal to 20 bits then the subject sequence is compared against the source sequence containing the regions of the union.

Title: Tubing Joint
Inventor: HAMA TOMIO
IPC: F16L37/12
Filed: 1996-05-30
Abstract: A tubing joint is provided herein. The tubing joint includes a joint body havinga cylindrical shape and a ring claw comprising an elastic plate material. An outer edge of the ring claw includes a bent portion which is bent in a tube-admitting direction and which is located in a ring groove which is formed in the joint body. The ring claw has a plurality of radially-directed, U-shaped, outer, notch sections which extend from the outer edge toward a centre of the ring claw. The U-shaped, outer, notch sections include a pair of spaced-apart, parallel, sidewall portions which are interconnected by a semi-circular connecting portion. The ring claw further has a plurality of radially-directed, inner, notch sections which extend from an inner edge of the ring claw toward the outer edge. The outer, notch sections and the inner, notch sections are alternatively arranged. The inner edge of the ring claw is arranged to bite an outer circumferential face of a tube which has been inserted in the joint body to prevent the tube from moving in thedirection of a tube-withdrawal. A release cylinder is provided which is located in the joint body and which is axially-slidable therein for pushing the inner edge of the ring claw to release the tube. The ring claw also has a plurality of inner ring sections, each of which is provided between adjacent outer ring sections. In addition, the ring claw has a plurality of connecting sections, each of which connects an end of one of the inner ring sections with an end of one of the outer ring sections which corresponds to the end of the inner ring section. Inner edges of adjacent connecting sections which mutually face one another and which form the side wall portions of each U-shaped, outer, notchsection, are arranged parallel to one another and substantially-perpendicular to the outer edge of the ring claw. This provides a tubing joint having a long life span, in which stress concentration can be avoided even if external force from the tube repeatedly works to the ring claw.
