Sep 17, 1999

Appl. No.:

09/398332

Inventors:

Jonathan M. Naft - Chagrin Falls OH
Wyatt S. Newman - Cleveland Heights OH

Assignee:

Becker Orthopedic Appliance Company - Troy MI

International Classification:

A61F 500

US Classification:

602 16, 602 26, 600592

Abstract:

A selectively lockable orthotic joint is provided that in one embodiment includes at least one pressure sensor and an electronic circuit associated with the pressure sensor for generating or providing a control signal indicative of pressure, force or other value sensed by the sensor. A mechanical orthotic joint is provided that has a locking mechanism that can be selectively locked and unlocked in response to the control signal.

H02K 1/18

US Classification:

318725, 318439, 318254, 310254, 310258

Abstract:

Brushless repulsion motors are presented, in which rotor coils switching signal detectors are selectively located in spaced angular relationship on the rotor and signaling sources are distributed around all or most of the stator circumference to allow looser tolerances for motor manufacturing and improved controllability of rotor coil actuation during operation. Asymmetric stator poles are also provided for brushless repulsion motors to mitigate torque ripple and vibration, in which the shape of the stator pole tips is tailored by varying the angular length of the pole section.

Assignee:

Becker Orthopedic Appliance Company - Troy MI

International Classification:

A61F 5/00

US Classification:

602 16, 602 23, 602 26

Abstract:

A selectively lockable orthotic joint is provided in which a pressure sensor having a thin layer of variably resistive material generates a control signal when an actuation force is applied to the sensor. An electronic circuit operatively connects the sensor to a mechanical orthotic joint that can be selectively locked and unlocked in response to the control signal. The control signal may be uniform in strength selectively locking and unlocking the joint. The control signal may also be variable in strength wherein the orthotic joint provides increasing or decreasing resistance to motion responsive to a corresponding increase or decrease in control signal strength. The device is suitable for use as a foot/ankle/leg orthotic having a foot sensor which selectively operates a mechanical knee joint.

Appl. No.:

8/631378

James D. Cawley - Shaker Heights OH

Assignee:

International Classification:

B32B 3106
B32B 3126

US Classification:

156 8911

Abstract:

A method for manufacturing an integral three dimensional object from laminations includes the steps of fabricating a plurality of first sheets of a first material composition, cutting each of the first sheets to form a contoured layer representing a cross-section of the three dimensional object and to form a waste material and discarding the waste material. The contoured layers are stacked in a desired sequence to form a stack of contoured layers which are then laminated. Subsequently, the contoured layers of the stack are secured to each other to form the integral three dimensional object. This method works particularly well with ceramic material sheets. If desired, a second type of sheet made of a fugitive material can also be cut to form a contoured layer representing a void in a cross-section of the three dimensional object. The contoured layers of the second sheets are then stacked along with the contoured layers of the first sheets to form the object. The laminated stack of contoured layers is then sintered.

International Classification:

B26D 718

US Classification:

83 24

Abstract:

An apparatus for forming an integral three-dimensional object from a plurality of individual laminations includes a cutting surface on which each of the laminations is individually deposited. A concentrated energy source cuts each of the plurality of laminations into a shape required for assembly of the laminations into the integral three-dimensional object. A transfer mechanism removes each of the cut laminations from the cutting surface and stacks each of the cut laminations on an assembly surface. The transfer mechanism includes a gripper face having a peripheral portion and a central portion. A mask is positioned on the gripper face. The mask has an apertured central portion corresponding to the cut lamination. A source of suction communicates with the gripper face and a valve mechanism selectively draws a suction on the gripper face peripheral portion, the gripper face central portion, both or neither. An electronic control device is provided for controlling the operation of the cutting surface, the concentrated energy cutter and the transfer mechanism.
