Patent number: 11346719Abstract: A Fourier-transform hyperspectral imaging system may include an optical imaging system configured to produce an image of an object, and an adjustable birefringent common-path interferometer module comprising a movable birefringent element and configured to produce interfering replicas of an input radiation which are delayed from each other by a phase delay adjustable by the moving birefringent element. The interferometer module may be configured to produce collinear replicas for entering optical rays parallel to said optical axis. The hyperspectral imaging system further comprises a two-dimensional light detector configured to receive the replicas and provide digital images of the object depending on said adjustable phase delay. The system also includes an analysis device configured to perform a Fourier Transform of the digital images to obtain a hyperspectral representation of the object.Type: GrantFiled: July 25, 2019Date of Patent: May 31, 2022Assignees: POLITECNICO DI MILANO, CONSIGLIO NAZIONALE DELLE RICERCHEInventors: Cristian Angelo Manzoni, Giulio Cerullo, Dario Polli, Antonio Perri, Fabrizio Preda, Gianluca Valentini, Andrea Bassi

Patent number: 11342949Abstract: A body-worn electronic device, including a loop antenna and a transmitter. The overall physical length of the loop antenna is less than 75% of the vacuum wavelength of a lower limit frequency of the operating frequency range of the transmitter, while the electrical length of the antenna is from 0.9 to 1.1 times the guided wavelength of the lower limit frequency of the operating frequency range of the transmitter. The loop antenna includes a plurality of conductors which are connected in series by inductors so as to increase the electrical length of the loop antenna.Type: GrantFiled: June 25, 2018Date of Patent: May 24, 2022Assignee: SONOVA AGInventors: Antonio Perri, Yves Oesch, Francois Callias

Patent number: 10841716Abstract: A hearing device includes a wireless communication unit, such as a radio frequency transceiver, and a two-half loop antenna. The antenna includes a conductor defining a first half loop and a second half loop configured to be fed in series with a radio signal from a radio frequency transceiver. The first half loop and the second half loop have mirror images forming respective half loops of the two-half loop antenna. Transverse segments of the first half loop and second half loop join the first half loop and the second half loop at a mid-point of the antenna near a feeding point. The physical antenna length of the antenna is less than ¾ of the wavelength of the radio frequency signal to be transmitted or received through the antenna. An electrical length of the antenna is approximately equal to the wavelength of the radio frequency signal to be transmitted or received.Type: GrantFiled: March 29, 2019Date of Patent: November 17, 2020Assignee: SONOVA AGInventors: Antonio Perri, Yves Oesch, Francois Callias
