Systems and methods for non-invasive blood monitoring devices are described. Electroactive materials and/or mechanical actuators can be used for non-invasive blood monitoring systems and measure blood pressure.

A catheter assembly may include a catheter adapter having a catheter extending from its distal end. The catheter may include a proximal end, a tip, and a length of tubing therebetween. The length of tubing may include one or more position indicators to indicate a position of the catheter relative to a vasculature. The catheter assembly may include an introducer needle extending through the length of tubing and comprising a sharp distal tip configured to introduce the catheter into the vasculature.

Methods of identifying a fluorochrome panel suitable for use in a flow cytometric protocol are provided. Methods of interest include receiving an instrument identifier and a request for N fluorochrome identifiers, selecting two or more subsets of N fluorochrome identifiers from a set of fluorochrome identifiers in a spectral matrix associated with the instrument identifier, and identifying the fluorochrome panel from the two or more subsets of N fluorochrome identifiers based on a numerical stability metric calculated for each of the two or more subsets of N fluorochrome identifiers using the spectral signatures associated with the two or more subsets of N fluorochrome identifiers. Systems and non-transitory computer readable storage media for practicing the invention are also provided.

Aspects of the present disclosure include methods for determining positional velocity of a particle in a flow stream of a particle analyzer. Methods according to certain embodiments include irradiating a sample having a particle in a flow stream of a particle analyzer with a first laser in a first interrogation region and a second laser in a second interrogation region, detecting light from the irradiated particle by a first photodetector channel in the first interrogation region and by a second photodetector channel in the second interrogation region, calculating a velocity of the particle in the flow stream based on the light detected by the first photodetector and by the second photodetector, determining a parameter of the particle in the flow stream and calculating a positional velocity of the particle in the flow stream based on the calculated velocity and the parameter of the particle. Systems and non-transitory computer-readable storage media configured to carry out the subject methods are also provided.

A system and method for estimating object distance and/or angle from an image capture device may obtain an image including a fiducial marker captured by an image capture device; extract a pixel width and/or a pixel height of the fiducial marker in the image space of the image; determine, based on the pixel width and/or the pixel height, a known width and/or a known height, and one or more calibration parameters, a distance of the fiducial marker from the image capture device; estimate, based on the pixel width, the pixel height, the known width, and the known height, a yaw angle of the fiducial marker with respect to the image capture device; determine, based on a slope of a positional vector of the fiducial marker, a roll angle of the fiducial marker with respect to the image capture device; and/or provide the distance, the yaw angle, and/or the roll angle.
