Patent number: 11035728Abstract: Interleaved data acquisition in optical spectroscopy is used to provide interference correction for time-varying interference. Measurements at a reference frequency are used to provide an estimate of the interference. These reference measurements are interleaved with the remaining measurements in order to provide estimates of the interference vs. time at relevant times. The interference being corrected can be spectrally structured or unstructured.Type: GrantFiled: April 30, 2019Date of Patent: June 15, 2021Assignee: Picarro, Inc.Inventors: Chris W.

Patent number: 9675193Abstract: The compression sock-donning aid includes an annular member from which a fixed handle extends radially. An actuator handle extends radially from the annular member. Moreover, the actuator handle is able to rotate with respect to the annular member and the fixed handle. The actuator handle is in mechanical connection with a plurality of fingers provided within a central hole of the annular member. Each of the plurality of fingers is able to extend inwardly or retract outwardly with respect to a central point. Rotation of the actuator handle extends or retracts the plurality of fingers.

Patent number: 8198885Abstract: A planar magnetic current sensor is described, incorporating a number of features designed to improve the efficiency and reliability of the basic sensor. The improvements comprise providing inner and outer conductive shields, an increased number of sensor elements for a given circuit board area, and distributing the resistance of the sensor circuitry. The conductive shields prevent high transient voltages and eddy currents that may damage the sensor itself. The depth of the inner and outer conductive shields is chosen to produce eddy currents sufficient to attenuate the magnetic fields associated with transient pulses of a frequency above the frequencies to be measured. An aperture is provided from the exterior of the conductive shields or sealing caps, if present, to an annular space, to allow an output signal to pass from the interior of the sensor to the exterior of the sensor for monitoring.Type: GrantFiled: May 18, 2006Date of Patent: June 12, 2012Inventor: Thomas Sorensen

Patent number: 8189259Abstract: A grating has a high diffraction efficiency into the minus first diffracted order in transmission, for both TE and TM polarizations. The incident angle may optionally be chosen so that the minus first diffracted order in reflection would be retroreflected back to the incident beam. The grating may be formed from various materials and/or layers, where the thicknesses of the individual layers may be determined by an optimization or simulation process. In one aspect, the grating may have four or more layers, formed with three or more materials. In another aspect, the grating may have a longitudinal refractive index profile that contains at least two local extrema, such as a maximum and/or minimum. Such a grating may be formed from three or more materials, two materials, or a single material that has a continuously varying refractive index. Any or all of the materials may have a continuously varying refractive index profile, as well.Type: GrantFiled: March 3, 2009Date of Patent: May 29, 2012Assignee: Ibsen Photonics A/SInventors: Johan Holm, Thomas Sorensen, Kristian Buchwald

Patent number: 7397233Abstract: A device for measuring alternating voltage in a conductor under test using a first set of capacitive voltage sensors 32a-f mounted on an electrically insulating support member. The sensors are disposed on the support member at spaced intervals along a first notional circle and are connected in parallel between an inner signal conductor 33 and a zero voltage reference conductor 37. A second set of capacitive voltage sensors 34a-f are mounted on the support member at spaced intervals along a second notional circle and are connected in parallel between an outer signal conductor 35 and the reference conductor 37.

Publication number: 20060251763Abstract: The inventors have used protein engineering to develop variants of fungal phospholipases.
