Publication number: 20240210180Abstract: A computer system determines a selected path to be taken by a vehicle. The system monitors alternative paths for the vehicle; based on the monitoring, determines that the vehicle approaches at least two alternative paths having different properties; determines a probability of the vehicle taking each of the at least two alternative paths having different properties; compares the probabilities of the at least two alternative paths to each other; and based on a result of the comparison of the probabilities, selects a selected path amongst the at least two alternative paths.Type: ApplicationFiled: December 18, 2023Publication date: June 27, 2024Applicant: VOLVO TRUCK CORPORATIONInventors: Linus NORDHOLM, Martin WILHELMSSON, Tobias SMIDEBRANT, Gabriel TRÖNNBERG, Johan BJERNETUN, Jenny BLOMQVIST, Johan LINDBERG, Johan AXELSSON

Patent number: 11331512Abstract: A system and method for determining or estimating the presence and effect of light-attenuating inhomogeneities in tissue when performing medical treatment or diagnostics using optical members in tissue. The system and method comprising inserting a plurality of optical members into the tissue, and then measuring by emitting light through a sub-set of optical members at a time, while measuring the light collected by another sub-set of optical members. Combining said measurement data with a model for light propagation in tissue, and setting up a system of equations. Solving the unknown attenuation values from said system of equations.Type: GrantFiled: April 6, 2020Date of Patent: May 17, 2022Assignee: SpectraCure ABInventors: Johannes Swartling, Ida Arvidsson, Johan Axelsson

Patent number: 9012869Abstract: A method and system for luminescence molecular imaging or tomography of a region of interest in a scattering medium is disclosed. The system comprises a non-linear luminescent marker material arranged in the scattering medium. Contrast and resolution of the imaging or tomography is thus improved. The non-linear marker is for instance configured to upconvert incoming light of an illumination wavelength. The non-linear power dependence of the marker enables further improvement of the imaging by using images taken with two or more excitation beams simultaneously.Type: GrantFiled: May 5, 2010Date of Patent: April 21, 2015Assignee: Lumito ABInventors: Stefan Andersson-Engels, Can Xu, Haichun Liu, Johan Axelsson, Niclas Svensson, Pontus Svenmarker

Patent number: 8986358Abstract: A method and system for controlling and adjusting light in interstitial photodynamic light therapy (IPDT) in a subject is disclosed. More particularly, a method for controlling the light in interstitial tumor photodynamic light therapy is described using a calculation method for determination of status of tissue during the PDT treatment. The status is used in a feedback loop to control the continued PDT treatment. Methods are disclosed that constitute pre-treatment and realtime dosimetry modules for IPDT on the whole prostate glandular tissue. The method includes reconstruction of the target geometry, optimization of source fiber positions within this geometry, monitoring of the light attenuation during the treatment procedure and updating individual fiber irradiation times to take into account any variation in tissue light transmission.Type: GrantFiled: August 15, 2007Date of Patent: March 24, 2015Assignee: Spectracure ABInventors: Sune Svanberg, Johan Axelsson, Johannes Swartling, Ann Johansson, Stefan Andersson-Engels
