Patent CA-2232561-A1 (CA)
Inventor: ANDREASSEN LAURITZ I
IPC: B23Q11/00
Filed: 1996-09-20
Abstract: An adaptor (6) is inserted between a cutting tool (1) and a clamping section of a tool machine. The adaptor comprises a tool clamping part (3) holding the tool, and an adaptor clamping part (5) which is held by the machine. Between the two parts (3, 5) there is a bearing (2) which controls the relative movement between the two parts (3, 5) in such a manner that this movement does not influence machined geometry, dimension or surface of the work piece machined by the tool, to any significant degree, and an elastic damping member (4) which ensures that a possible relative movement between the two parts (3, 5) is damped down to a desired degree. Possible vibrations in the tool are thereby kept down on a level where they do not contribute to amplify the normal sound pressure from the machining operation, and an efficient noise suppression is achieved.

IPC: A61N1/36
Filed: 1997-06-25
Abstract: A method for operating an implantable therapy system to conserve energy includes providing an implantable sensing device that generates a signal as a function of a physiological parameter of a patient during a treatment period.  The signal is monitored during at least portions of the treatment period to detect a physiological event for use in controlling therapy of the patient during the treatment period. Energy consumption by the sensing device is terminated during the treatment period for at least portions of the treatment period when signal monitoring is not performed. Another method for operating an implantable therapy system for conserving energy includes providing an implantable component for performance of a function during a treatment period for the therapy system. The implantable component is operable in at least a first state during the treatment period and a second state outside of the treatment period; the first state using more energy than the second state. The implantable component is operated in the first state when performance of the function during a treatment period is required and operated in the second state when performance of the function is not required outside the treatment period. Another method of operating an implantable therapy system includes monitoring a periodic physiological parameter for controlling therapy of a patient during a treatment period. The measured physiological period for the parameter of the patient is compared to at least one predetermined period threshold to determine nonperiodic behavior of the monitored periodic physiological parameter and suspending therapy of the patient as a function thereof. Systems for use with such methods are also provided.

Patent CA-2259889-A1 (CA)
Title: Sports brace
Inventor: GODWIN ANDREW
IPC: A61F5/37
Filed: 1999-01-22
Abstract: A shoulder brace consists of a figure "8" strap tensioned between a lower loop anchored around a thigh and a collar or sleeve worn on an opposite upper arm corresponding to an injured shoulder so as to extend the upper loop diagonally across the torso, thereby immobilizing the upper arm to prevent shoulder abduction and external rotation after, for example, shoulder dislocation. The upper and lower loops crossover adjacent the hip, with lower loop mugged under the crotch so as to allow relatively unrestricted movement of the thigh, for example, during exercise. The shoulder brace is thus well adapted for use as a sports brace.
