  • Patent number: 10132994
    Abstract: Methods and systems for writing a Bragg grating along a grating region of an optical fiber through a polymer coating of the optical fiber are provided. A light beam of ultrafast optical pulses is impinged on the grating region, the ultrafast optical pulses being characterized by writing wavelength at the grating region to which the polymer coating is substantially transparent The light beam is diffracted through a phase mask so as to form an interference pattern defining the Bragg grating at the grating region of the optical fiber. The light beam is also focussed such that the intensity of the optical pulses is below a damage threshold within the polymer coating, and above an FBG inscription threshold within the grating region of the fiber. Optical fiber having Bragg gratings and improved mechanical are also provided.

  • Patent number: 10084287
    Abstract: The mid-infrared laser system has an amplifier including at least one pump laser adapted to generate a pump laser beam and a length of fiber made of a low phonon energy glass and having at least one laser-active doped region between a first end and a second end, and a seed laser to generate a seed laser beam having a seed optical spectrum in the mid-infrared. The seed laser beam is launched into the first end to generate a mid-infrared laser beam outputted from the second end via stimulated emission upon pumping of the at least one laser-active doped region with the pump laser beam. When the power of the pump laser exceeds a spectrum modification threshold, the mid-infrared laser beam has an output optical spectrum being broadened relative to the seed optical spectrum.

  • Patent number: 10070254
    Abstract: Disclosed methods and systems allow provision of zone-based services to users. Both zones and users have their own profiles. A detection system allows determining when users enter or leave a zone. A pairing is calculated between compatible elements of zone profiles, or between compatible elements of the user profiles. Delivery of zone-based services may conditionally be granted according to a level of the pairing. Pairings may also be established between users or between zones. A server may manage profiles for the zones and for the users.

  • Publication number: 20180079629
    Abstract: An electromechanical system operates through physical interaction with an operator, and includes a plurality of joints providing multiple degrees of freedom (DOF), including actuated joints and unactuated joints. The unactuated joints are distal with respect to the actuated joints and are in redundant DOF to the actuated joints. The system includes a plurality of actuators each configured to actuate one or more of the actuated joints, and a plurality of sensors each positioned with respect to a respective one of the actuated and unactuated joints. Each sensor is configured to measure corresponding joint data indicative of a position or angle of the respective actuated or unactuated joints. A controller in communication with the sensors receives the measured joint data as feedback signals, generates control signals using the feedback signals, and transmits the control signals to the actuators to thereby control an actuation state of the actuators.

A force is imparted on the first and second kinematic links such that an angular displacement of the first and second kinematic links about the respective axis of rotation is achieved. The angular displacement of the first and second kinematic links about the respective axis of rotation is determined. The movement device is moved along the X axis and/or the Y axis in response to the determination of the angle of rotation of the first and second kinematic links about the respective axis of rotation until first and second kinematic links are vertical.
