Publication number: 20240125720Abstract: The invention teaches a method proposing two new indices for evaluating thermal evolution in oils from different basins and organofacies. The first index is based on the distribution ratio of high molecular weight sulfur compounds, belonging to the DBE 6 (benzothiophene) and DBE 9 (dibenzothiophene) series. The second index, called TEI, was created from the profile of aromatic hydrocarbons and molecules containing N, O and S. Both parameters were obtained from the direct characterization of the oils, by using the photoionization at atmospheric pressure (APPI) technique combined with Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS).Type: ApplicationFiled: September 28, 2023Publication date: April 18, 2024Inventors: RODRIGO CABRAL DA SILVA, DANIELLE MITZE MULLER FRANCO, YGOR DOS SANTOS ROCHA, JOELMA PIMENTEL LOPES, GABRIEL HENRY MORAIS DUFRAYER, MÁRIO DUNCAN RANGEL, ROSANA CARDOSO LOPES PEREIRA, BONIEK GONTIJO VAZ, TAYNARA RODRIGUES COVAS, JUSSARA VALENTE ROQUE, ROSINEIDE COSTA SIMAS

The processor is configured to receive heart-rate measurement data and exercise workload data for an individual of the wearable device. The memory stores instructions that cause the processor to obtain the heart-rate and exercise workload of the individual, normalize the heart-rate with respect to the individual's maximum heart-rate to provide a data pair of normalized heart-rate (HRn) and exercise workload (w), and apply a probabilistic model that relates HRn to w and maximum oxygen uptake to provide an estimate of maximum oxygen uptake (VO2max) of the individual.Type: ApplicationFiled: December 30, 2020Publication date: February 15, 2024Inventor: Mario Costa

Patent number: 11877732Abstract: A biopsy needle has a cylindrical shell outer cannula and a stylet consisting of an inner stylet and outer stylet, both of which are inserted into the cylindrical cannula. The outer stylet has a series of strain relieved slits which provide bending over a deflection region in one direction, and the outer stylet is formed from a material such as a shape memory alloy (SMA) having a superelastic phase. The deflection is generated by an SMA wire spanning a deflection extent and attached to the outer stylet on either side of the deflection extent. The inner stylet, when positioned inside the outer stylet, has one or more actuation fibers which couple optical energy into the SMA wire, causing a deflection of the outer stylet over the deflection extent, with the optical energy provided to the actuation fibers for control of the deflection. Additional fibers may be placed in the inner stylet to measure temperature and to measure deflection.Type: GrantFiled: May 4, 2020Date of Patent: January 23, 2024Assignee: Intelligent Fiber Optic Systems CorporationInventors: Seok Chang Ryu, Mark Cutkosky, Richard J.

Patent number: 11606132Abstract: The application relates to beam management for a client device in a power saving state. When the client device is in the power saving state, the client device monitors serving beams of a network access node based on a serving beam configuration. The serving beam configuration indicated the serving beams to be monitored by the client device in the power saving state. If the client device detects a beam failure during the serving beam monitoring in the power saving state, the client device performs a beam reconfiguration procedure. The beam reconfiguration procedure informs the network access node about the change in serving beam status and allows the network access node to update the serving beam configuration.Type: GrantFiled: January 27, 2021Date of Patent: March 14, 2023Assignee: Huawei Technologies Co., Ltd.Inventors: Petteri Kela, Mario Costa, Johan Christer Qvarfordt
