Patent CA-2258602-A1 (CA)
Inventor: DAWSON JAY W
IPC: G01R15/24
Filed: 1996-11-21
Abstract: A fiber optic subassembly for a Faraday-effect current sensor has an optical sensing fiber supported by a tubular holder (12) in a square or rectangular configuration, with the three of the four corners thereof designed with bends which have a net zero bend-induced birefringence. The bends are formed by providing two loops which have effective angles of about 90~, the two loops lying in orthogonal planes, such that the fast axis of birefringence in the first loop is parallel to the slow axis of birefringence in the second loop, and the slow axis of birefringence in the first loop is parallel to the fast axis of birefringence in the second loop. In this manner, retardance accumulated in the first loop is offset by retardance accumulated in the second loop. If the loops are substantially identical, the offsetting of the retardance is effectively complete such that the bend exhibits negligible bendinduced birefringence.

Title: Tooth extraction device and method of using the same
Inventor: ROSSI DOROTHY FERN
IPC: A61C3/14
Filed: 1999-01-20
Abstract: The tooth extraction device includes a pair of handle members with opposing jaws and a force limiting spring or biasing member interconnecting the handle members to provide an adjustable and selective force to be applied to a targeted tooth. A pin is mounted between the handle members and may be positioned so that more or less clamping force is exerted upon the tooth. The jaws of the handle members have contacting surfaces which surround a concave or recessed area, and the jaws nave a curved shape enabling the jaws to effectively grasp teeth of different sizes and at different locations in the mouth. The method of the invention includes the steps of preselecting a desired amount of clamping force to be applied to the targeted tooth by choosing a first set point, engaging the tooth with the extraction device and, if desired, adjusting the amount of force applied to the tooth by selecting a different set point reflective of a different amount of clamping force.

Title: Rotary seal with relief angle for controlled tipping
Inventor: BAEHL JEFF
IPC: F16J15/32
Filed: 1999-10-29
Abstract: A sealing device for sealing the gap between two relatively moving members is provided with a pivot point on its cross-sectional perimeter. As pressure against the seal increases, the seal rotates about the pivot point, resulting in an increased sealing surface area on the seal. Additionally, a recess is provided on the cross sectional perimeter, advantageously offering a more frictionless sealing relationship between the seal and the moving member. Further, a recess is provided on outer portion of the cross sectional perimeter on a surface of the seal that would contact an energizer ring, the recess eliminating a dynamic interface between the energizer ring and the seal.

This subassembly is then placed into the regulator body and a mounting plate of the valve guide is screwed down into the regulator body. The lever is lifted up and its actuator end is inserted through an opening apt the bottom of the valve stem of the regulator's diaphragm assembly. An orifice member is then threadedly installed into the regulator body inlet, the end of the orifice member having a valve seat which becomes seated in the end of the plunger valve guide. In an alternate embodiment, the orifice is formed as part of the plunger valve guide.

Patent CA-2307207-A1 (CA)
Inventor: LINNEBJERG STEVEN
IPC: A61M5/315
Filed: 1998-10-23
Abstract: The hollow cylindrical syringe body (10) has a channel (12) of uniform diameter. A fluid port (14) is situated at one end. The other end defines a funnel-like opening (20) with a diameter greater than that of the channel (12). A piston (24) is moved along the channel (12) by the end of a push rod (26) which is received through the channel opening (20). A ball (30) on the push rod (26) lodges in a socket (36) in the piston (24) as the rod pushes the piston (24) toward the port (14). The socket (36) is formed of resilient fingers (32, 34) which are held by the channel wall in position to retain the ball (30) in the socket (36), such that the piston (24) can be moved along the channel (12) to load the syringe. When the socket (36) aligns with the funnel-like opening (20) of the channel (12), the socket fingers (32, 34) spread apart to release the ball (30) from the socket (36), permitting the push rod (26) to be removed from the loaded syringe.

Abstract: A method, and a system, for detecting and displaying clustered microcalcifications in a digital mammogram wherein a digital mammogram is obtained (100), automatically cropped (200) to a breast area sub-image, and processed by means of an optimized difference of Gaussians filter to enhance the appearance of potential microcalcifications in the sub-image. The potential microcalcifications are thresholded, clusters are detected (300), false positive cluster detections are removed by means of a Gabor filter (800), features are computed for the remaining detected clusters, and the clusters are classified (400) as either suspicious or not suspicious by means of a neural network. Suspicious clusters are processed for display (600) and the locations in the original digital mammogram of the suspicious clustered microcalcifications are displayed (700). The results of the system are optimally combined with a radiologist's observation of the original mammogram by combining the observations with the results, after the radiologist has first accepted or rejected individual detections reported by the system.
