Abstract: In some implementations, a system may identify a plurality of sensor devices that are associated with a physical environment. The system may receive an indication that a set of sensor devices (e.g., that includes two or more sensor devices) are to be associated with a virtual sensor that is associated with the physical environment. The system may generate, based on receiving the indication, the virtual sensor. The system may obtain sensor data that was captured by the set of sensor devices. The system may process the sensor data to determine a set of parameters associated the virtual sensor. The system may determine, based on the set of parameters associated with the virtual sensor, that a physical environment condition is satisfied. The system may cause, based on determining that the physical environment condition is satisfied, one or more actions to be performed.

Abstract: A method and system for determination of oxygen saturation in blood flowing in a vessel using magnetic resonance (MR). An MR image sequence is acquired with different echo time (TE) encoding, and different Fourier velocity encoding (FVE). A Fourier transformation is applied along the velocity dimension to determine a velocity distribution of tissue signals in each voxel of the image sequence. Tissue signals indicative of moving tissues are separated from tissue signals indicative of static tissue, based on the velocity distribution. Oxygen saturation in blood may then be determined using only the tissue signals indicative of flowing blood.
