  • Capacitance manometer with improved baffle for improved detection accuracy
    Patent number: 11287342
    Abstract: A capacitive manometer offering improved measurement accuracy is disclosed which includes at least one electrode structure having an inner electrode structure and an outer electrode structure separated by at least one gap, at least one flexible diaphragm having at least one conductive material positioned thereon or integrated therein may be positioned in movable relation to the electrode structure and in proximity to the electrode structure, and at least one non-planar baffle less prone to transient measurement errors having an inner baffle structure and an outer baffle structure separated by at least one baffle orifice positioned distantly from the electrode structure proximate to the flexible diaphragm.

  • LIGHT GUIDE APPARATUS AND FABRICATION METHOD THEREOF
    Publication number: 20210173141
    Abstract: A light guide apparatus that can redirect light impinging on the apparatus over a wide range of incident angles and can concentrate light without using a tracking system and methods for fabrication. This apparatus uses conditions of total internal reflection and refraction near the critical angle for total internal reflection (near TIR) in order to trap light within the apparatus.
