Patent number: 11796577Abstract: A device includes a first oscillator, a second oscillator and a frequency comparison block. The first oscillator includes a first LC tank circuit and is designed to generate first sustained oscillations at a first resonant frequency. The second oscillator includes a second LC tank circuit and is designed to generate second sustained oscillations at a second resonant frequency. The frequency comparison block is designed to perform a comparison of the frequencies of the second sustained oscillations and the first sustained oscillations to determine a change in inductance in one of a first inductor of the first LC tank circuit and a second inductor of the second LC tank circuit. One of the oscillators serves as a reference oscillator, and enables determination of the change in inductance to be immune to changes in environmental conditions.Type: GrantFiled: August 3, 2021Date of Patent: October 24, 2023Assignee: Ningbo Aura Semiconductor Co., LimitedInventors: Augusto Manuel Marques, Nigesh Baladhandapani

Patent number: 11717154Abstract: The present disclosure relates to an apparatus and method that can be used to remotely acquire high resolution depth resolved images from a sample. The apparatus employs an adapter to an imaging device, where the adapter uses a minimum of components to produce interferometry patterns on the input facet of the imaging device. The imaging device can be a bundle endoscope terminated on a camera sensor or on several camera sensors or simply a camera sensor. In conjunction with a swept source or a broadband source, at least one camera sensor may be employed to provide optical coherence tomography (OCT) images of the sample. When the imaging device uses a bundle of optical fibers, the apparatus and method can provide OCT images tolerant to bending of the bundle.Type: GrantFiled: July 25, 2019Date of Patent: August 8, 2023Assignee: University of KentInventors: Adrian Podoleanu, Manuel Marques, Michael Hughes

Patent number: 11690516Abstract: The present specification relates to Master-Slave (MS) interferometry for sensing the axial position of an object subject to optical coherence tomography (OCT) imaging, and to MS-OCT applied to curved and axially moving objects. The methods and apparatuses allow producing OCT signals from selected depths within the object irrespective of its axial position in respect to the imaging system. Images are obtained for curved objects that are flattened along a layer of interest in the object, images that are used to provide OCT angiography images less disturbed by axial movement or lateral scanning.Type: GrantFiled: November 18, 2020Date of Patent: July 4, 2023Assignee: University of KentInventors: Adrian Podoleanu, Manuel Marques, Adrian Bradu, Adrian Fernandez Uceda

Patent number: 11566537Abstract: A water-cooled compressor housing assembly for a turbocharger includes a compressor housing that defines an open-ended cavity extending axially downstream into the compressor housing, and a separately formed cover that is affixed to the compressor housing so as to close the open end of the cavity and thereby define a coolant passage for a liquid coolant to be circulated through. A coolant inlet and a coolant outlet are provided for supplying coolant into and exhausting coolant from the coolant passage. The compressor housing has a simplified geometry that is manufacturable by sand casting without needed a sand core for the coolant passage, or by die casting.Type: GrantFiled: October 12, 2020Date of Patent: January 31, 2023Assignee: Garrett Transportation I Inc.Inventors: Manuel Marques, Olivier Millotte, Emeric Genin, Jean-Pierre Toniolo
