Publication number: 20210068351Abstract: An approach for controlling light exposure of a light sensitive object is described. Aspects of this approach involve using a first set of radiation sources to irradiate the object with visible radiation and infrared radiation. A second set of radiation sources spot irradiate the object in a set of locations with a target ultraviolet radiation having a range of wavelengths.

Patent number: 10935404Abstract: A MEMS sensor for measuring at least one measured variable, especially a density, a flow and/or a viscosity, a flowing fluid, is described, comprising: at least one microfluidic channel having a channel section excitable to execute oscillations; and an exciter system for exciting a desired oscillation mode, causing the channel section to execute oscillations in a predetermined plane of oscillation.

Publication number: 20210055262Abstract: Eddy current sensing is governed by the diffusion equation of magnetoquasistatic fields. As such the eddy current sensor's proximity to the object to be inspected (i.e., “liftoff”) significantly affects the sensor's response signal. Methods and apparatus are disclosed for improving performance for an eddy current sensor, though they may also be used for other sensor types. These solutions are beneficial for both single channel eddy current sensors and arrays, and are particularly beneficial for measuring parts with complex surfaces. In some aspects improved performance is achieved by varying the stiffness of the mechanical support for the sensor. Some mechanical supports may exhibit anisotropic stiffness. After performing a scan with an eddy current array, a multi-channel shape filtering module is applied to improve defect detection. The module reduces the variability of defect response measured due to the unpredictability of the defect location transverse to the scan direction.Type: ApplicationFiled: April 9, 2019Publication date: February 25, 2021Applicant: JENTEK Sensors, Inc.Inventors: Neil J Goldfine, Todd M Dunford

Publication number: 20210038087Abstract: An apparatus, system, and method monitors the motion, breathing, heart rate and sleep state of subjects, e.g., humans, in a convenient, non-invasive/non-contact, and low-cost fashion. More particularly, the motion, breathing, and heart rate signals are obtained through processing applied to a raw signal obtained in a non-contact fashion, typically using a radio-frequency sensor. Periods of sleep disturbed respiration, or central apnea can be detected through analysis of the respiratory signal. The mean heart rate, and derived information, such as the presence of cardiac arrhythmias can be determined from the cardiac signal. Motion estimates can be used to recognize disturbed sleep and periodic limb movements. The sleep state may be determined by applying a classifier model to the resulting streams of respiratory, cardiac and motion data. A means for display of the sleep state, respiratory, cardiac, and movement status may also be provided.Type: ApplicationFiled: July 2, 2020Publication date: February 11, 2021Applicant: RESMED SENSOR TECHNOLOGIES LIMITEDInventors: Conor HENEGHAN, Conor Hanley, Niall Fox, Philip De Chazal
