  • Patent number: 9239226
    Abstract: An apparatus for measuring the quantity and optical parameters of a liquid in a container using the principle of optical low coherence reflectometry is provided, the apparatus having: a source arm with a low coherence light source; a reference arm including a reference lens, a mirror, means for adjusting the distance between the reference lens and the mirror and means for measuring the distance between the reference lens and the mirror; a test arm with a test lens; means for dividing the output of the source arm between the test arm and the reference arm; means for combining light reflected back into the reference arm and the test arm to create an interference signal; and means for detecting and analyzing the interference signal.
    Type: Grant
    Filed: January 23, 2014
    Date of Patent: January 19, 2016
    Assignee: The Governors of the University of Alberta
    Inventors: Robert Fedosejevs, Ilya Utkin, Sunita Sindhu, Ying Yin Tsui

  • Patent number: 8292834
    Abstract: Ultrasound stimulation devices and related techniques are disclosed. An ultrasound transducer for generating ultrasound energy is carried by a transducer housing that seals the transducer and may also include a positioning element for positioning the transducer proximate an application area to which generated ultrasound energy is to be applied. The transducer housing may also carry such components as a battery, a wireless receiver, and a controller. The same housing or a separate sensor housing may include an ultrasound sensor that provides feedback to the ultrasound transducer or its controller, illustratively through a wireless transmitter.
