  • Publication number: 20230037654
    Abstract: Disclosed herein is a system for evaluating a user during a physical cannulation simulation. The system includes a physical cannulation simulator and one or more sensors configured to measure data during the physical cannulation simulation by the user using the physical cannulation simulator. The system further includes one or more processors configured to receive the data measured by each of the one or more sensors and calculate metrics using the data. The one or more processors are further configured to apply a model to the metrics to determine a composite simulation success score and compare the composite simulation success score to a threshold score. In response to comparing the composite simulation success score to the threshold score, the one or more processors are configured to output an indication of one or more of an absolute performance or a relative performance for the first user during the physical cannulation simulation.

  • Patent number: 11169604
    Abstract: A method for determining gaze calibration parameters for gaze estimation of a viewer using an eye-tracking system. The method comprises obtaining a set of data points including gaze tracking data of the viewer and position information of at least one target visual; selecting a first subset of the data points and determining gaze calibration parameters using said first subset. A score for the gaze calibration parameters is determined by using the gaze calibration parameters with a second subset of data points, wherein at least one data point of the subset is not included in the first subset. The score is indicative of the capability of the gaze calibration parameters to reflect position information of the at least one target visual based on the gaze tracking data. The score is compared to a candidate score and if it is higher, the calibration parameters are set to the candidate calibration parameters and the score to the candidate score.

  • Publication number: 20200225745
    Abstract: A gaze tracking model is adapted to predict a gaze ray using an image of the eye. The model is trained using training data which comprises a first image of an eye, reference gaze data indicating a gaze point towards which the eye was gazing when the first image was captured, and images of an eye captured by first and second cameras at a point in time. The training comprises forming a distance between the gaze point and a gaze ray predicted by the model using the first image, forming a consistency measure based on a gaze ray predicted by the model using the image captured by the first camera and a gaze ray predicted by the model using the image captured by the second camera, forming an objective function based on at least the formed distance and the consistency measure, and training the model using the objective function.

  • Patent number: 9464994
    Abstract: Highly sensitive and tunable RF sensors that provide detection and analysis of single cells and particles are provided. The tunable RF sensors are configured as tunable interferometers, wherein cells or particles to be analyzed are passed through a channel, such as a microfluidic channel, across waveguides corresponding to reference and test branches of the interferometers. A network analyzer coupled to the interferometers can be configured to measure a plurality of scattering parameters, such as transmission scattering coefficients (S21) of the reference and test branches, to evaluate characteristics of cells passing through the channel. A plurality of tunable interferometers may be employed, each interferometer operating in different frequency bands such that information obtain from the plurality of interferometers may be combined to provide further information.

  • Publication number: 20080078517
    Abstract: A tissue product having a softening composition applied to at least one side is generally disclosed. The softening composition includes a polysiloxane micelle having a core polysiloxane and an outer layer polysiloxane. The core polysiloxane is more hydrophobic than the outer layer polysiloxane. In one embodiment, the core polysiloxane is an amino-functional polysiloxane, and the outer layer polysiloxane is a polyether polysiloxane. The softening composition can also contain other optional ingredients, such as surfactants and beneficial agents.

  • Publication number: 20050274470
    Abstract: The fluid intake rate of a tissue product having at least one hydrophobic exterior layer can be increased significantly by the addition of apertures through the hydrophobic exterior layer to the tissue product's hydrophilic interior layer. The apertures allow for fluid to be absorbed by the hydrophilic interior layer, while leaving the hydrophobic exterior layer dry to the touch. The size, number and spacing of the apertures can be controlled to manage the absorbent properties of the tissue product. In one embodiment, a three-ply tissue product has two exterior hydrophobic plies each having a plurality of apertures extending from the surface of both exterior plies through the plies to a hydrophilic interior ply.

  • Patent number: 6936136
    Abstract: The disclosed invention is directed to pulp fibers suitable for forming a wet-laid paper product which include amino-functionality which is non-extractable in an aqueous phase. The pulp fibers may be prepared by applying an amino-functional additive to a fibrous web prior to the finishing operation at a pulp mill. The fibrous web may then be repulped at a papermaking machine to form a paper web which includes the amino-functionalized fibers of the present invention. A paper web formed of the amino-functionalized fibers may display unique and/or improved reactivity toward certain papermaking additives.
