Publication number: 20230352173Abstract: Embodiments described relate to techniques for identifying and characterizing biological structures using machine learning techniques. These techniques may be employed to enable a device to identify the particular type of tissue and/or cells (e.g., platelets, smooth muscle cells, or endothelial cells) in, for example, a biological structure, which may be a tissue or a lesion of a duct (e.g., vasculature) in an animal (e.g., a human or non-human animal), among other structures. The machine learning techniques may use raw impedance spectroscopy measurement data in addition to values derived from that raw data. In addition, the machine learning techniques may be used to select frequencies at which to measure impedance and select features to extract from the measured impedance at the selected frequencies to arrive at a small set of frequencies that allow for reliable differentiation.Type: ApplicationFiled: December 23, 2022Publication date: November 2, 2023Applicant: Sensome SASInventors: Gor Lebedev, Pierluca Messina

Patent number: 10014800Abstract: An electricity generator including a first converter suitable for converting a variation of an energy to be harvested into a corresponding excess of electrical charges. The generator includes a circuit for collecting the excess of electrical charges, the circuit has a first controllable mechanical switch, and a control device for the first switch designed to control the switching of the switch to its closed position when the excess of electrical charges exceeds a first predetermined threshold. The switch is a magnetic switch and the control device comprises a variable magnetic field source which controls the switching of the first switch to its closed position only at the time when the excess of electrical charges exceeds the first predetermined threshold.Type: GrantFiled: October 15, 2013Date of Patent: July 3, 2018Assignees: Commissariat à l'énergie atomique et aux énergies alternatives, Institut Polytechnique de Grenoble, Centre National de la Recherche ScientifiqueInventors: Bernard Viala, Gor Lebedev, Jérome Delamare, Lauric Garbuio, Thomas Lafont, Orphée Cugat
