Inventor: VIDAL CLAUDE A
IPC: A61M13/00
Filed: 1995-06-09
Abstract: A surgical handle (12) for use with an endoscopic instrument (14) that is insertable into a body cavity insufflated with a gas. The surgical handle (12) includes a housing having a mount that defines an opening for receiving the endoscopic instrument. A first elongated pusher tube is located within the housing and aligned with the mount opening. The pusher tube includes an interior passage that is in fluid communication with the endoscopic instrument. A first actuator moves the pusher tube longitudinally with respect to the mount opening. The interior passage is sized to permit the flow therethrough of insufflation gas escaping from the body cavity up to a predetermined rate, the rate being set at an amount that will not result in deflation of the body cavity.

Abstract: An apparatus and method for burnishing compact discs to remove scratches and other blemishes therefrom includes a table upon which is fixed a platform set into which are one or more rotatable platters each disposed to accept a single compact disc. A burnishing assembly is pivotally mounted to the table enabling the burnishing assembly to be raised and lowered. The burnishing assembly includes a frame, a plurality of cylindrical rollers and a drive motor. In operation, a roll of burnishing material is carried on the feed roller and follows a path around the burnishing assembly so that when the burnishing assembly is in its lowered and locked position the burnishing material is engaged in frictional contact with the exposed surfaces of the rotating compact discs. Provision is also made to advance the burnishing material across the face of the rotating compact discs and impart a reciprocating motion to the burnishing assembly in order to enhance the burnishing operation. A method of removing scratches and blemishes from compact discs is provided using the herein described apparatus. Furthermore, a method by which a large quantity of damaged compact discs can be repaired in an economical and commercial basis is also provided.

Abstract: A method for speeding up execution of neural networks suitable for processing input signals evolving slowly through time, such as, voice, radar, sonar, video signals. The method comprises storing, for the neurons in at least one level of the network, an activation value at a certain instant and comparing it with an activation value computed at a subsequent instant. If the activation values are equal, the neuron carries out no activity. If the activation values are not equal, the difference in activation values is multiplied by the interconnection weights and carried to the neurons connected in the next level.

Title: Laser demolding apparatus and method
Inventor: WALKER CRAIG WILLIAM
IPC: B29C33/22
Filed: 1996-04-29
Abstract: An automated demolding apparatus for mechanically separating contact lens mold portions of a mold assembly. The mold assembly includes a first front mold portion having a central mold section with a surrounding flange, and a corresponding second back mold portion also having a central mold section with a surrounding flange, with a molded contact lens being formed between the front and back mold portions. The demolding apparatus includes restraining fingers positioned between and on opposite sides of the spaced flanges of the first and second mold portions and against the flange of the first mold portion. A separating fixture includes separating fingers positioned between and on opposite sides of the spaced flanges of the first and second mold portions and against the flange of the second mold portion. Before demolding, the second mold portion is irradiated by a laser beam, which is absorbed thereby to cause a substantial temperature gradient between the second mold portion and the contact lens being demolded. The temperature gradient causes a differential expansion and shifting of the surface of the heated second mold portion relative to the surface of the lens to lessen the adhesion therebetween to assist in separation of the mold portions, while leaving the lens in the first mold portion. During demolding, the separating fixture is subjected to a substantially vertical prying motion relative to the restraining fingers to separate the second mold portion from the first mold portion.

Patent CA-2183779-A1 (CA)
Inventor: GROSS NORBERT
IPC: B23K26/044
Filed: 1996-08-20
Abstract: In a method for monitoring and positioning a beam or jet (3) for operating on a workpiece, a first sensor (7) (eg. in the case of a beam, a seam detecting system) ahead of the beam or jet, and/or a preset value, determines the path to be followed by the beam or jet (3). A second sensor (9) behind the beam or jet (3) monitors the action of the beam or jet. The preset value, or the readings obtained by the first sensor (7) regarding a required position of the beam or jet (3), is or are compared with readings obtained by the second sensor (9) regarding an actual position of the beam or jet (3), taking account of the velocity-dependent relative displacement between the beam or jet and the workpiece. The beam or jet (3) is corrected to a basic position if the actual position deviates from the required position.
