Patent number: 8515224Abstract: A method for writing a Bragg grating in a rare-earth doped glass optical waveguide is provided. Ultrafast optical pulses are generated, preferably in the femtosecond range and having a writing wavelength in the range of 300 nm to 700 nm and an intensity sufficient to induce a change of refractive index in the rare-earth doped glass waveguide through densification. The optical pulses are diffracted using a phase mask, to generate an interference pattern having a pitch providing a fundamental Bragg resonance corresponding to the target wavelength to be reflected by the grating. The interference pattern is impinged on a region of the rare-earth doped glass waveguide, which is heated to a temperature above a threshold of about 350° C., for a predetermined heating period. Advantageously, the heating step allows the elimination of photodarkening effects which would otherwise be present in the waveguiding properties of the waveguide.Type: GrantFiled: July 29, 2010Date of Patent: August 20, 2013Assignee: Universite LavalInventors: Real Vallee, Martin Bernier

Patent number: 8435964Abstract: Aortic valve stenosis (AS) is a chronic process related to a progressive mineralization of the aortic root and valve cusps. We found in human AS valves a high level of expression and enzymatic activity of ectonucleotide pyrophosphatase/phosphodiesterase-1 (ENPP-1), which correlated to the degree of mineralization. In vitro, inhibition of ENPP activity with ARL 67156 significantly reduced calcification of isolated valve interstitial cells. In a rat model of cardiovascular calcification, ARL 67156 significantly reduced calcification of the aortic root and valve cusps. This is the first study to demonstrate that increased expression and activity of ENPP-1 promotes the mineralization process in AS valves. Hence, inhibition of ectonucleotidase may represent a novel target of therapy for this frequent and serious cardiovascular disease.Type: GrantFiled: October 20, 2010Date of Patent: May 7, 2013Assignee: Universite LavalInventor: Patrick Mathieu

Patent number: 8392023Abstract: A robotic system includes a robot for moving a payload in response to a calculated input force. Sensors in respective sensor housings are connected to a handle, each sensor including a light emitter and receiver. The sensors measure a light beam received by a respective receiver. A controller calculates the calculated input force using received light. Each sensor housing modifies an interruption of the light beam in a sensor when the actual input force is applied, and the controller controls the robot using the calculated input force. A method of controlling the robot includes emitting the light beam, flexing a portion of the sensor housing(s) using the actual input force to interrupt the light beam, and using a host machine to calculate the calculated input force as a function of the portion of the light beam received by the light receiver.
