  • Patent number: 12102434
    Abstract: A method for training a system for measuring or estimating or both of a user's response to a stimulus and for classifying the response is disclosed. The system is trained using a test stimulus presented to one or more users. One or more images of the users' face are captured and simultaneously EEG signals of the users are captured. One or more emotional features are derived from the facial data of the users. One or more cognitive features and emotional features are derived from the EEG signals of each of the users, and a training dataset is created by correlating the one or more emotional features from the facial data, one or more cognitive and emotional features from the EEG signals with one or more features associated with the test stimulus. Created training dataset is used for measuring or estimating or both of a user's response to the stimulus.

    Abstract: Determining lung capacity of includes capturing an audio waveform of the user performing an utterance presented to a user. A video of the user performing the utterance can be captured. The captured audio waveform and the video are analyzed for compliance. Based on the audio waveform, an indicator of respiratory function is determined. The indicator is compared with a reference indicator to determine health of the user.

In a keratometer as a keratoconus determination apparatus, a prediction model for keratoconus is stored in a memory. The prediction model is a logistic regression model in which three parameters that are a steep meridian refractive power, a flat meridian refractive power, and a value indicating whether or not a subject eye has a with-the-rule astigmatism, are independent variables, and a probability of keratoconus is a dependent variable. A control unit substitutes the three parameter values into the prediction model, to obtain a probability of keratoconus. When the probability is greater than a cutoff value, the subject eye is determined to be suspected of having keratoconus.

    Abstract: A tissue resecting instrument includes a drive assembly coupled to an inner cutting shaft and configured to drive translation and/or rotation of the inner cutting shaft, a trigger coupled to the drive assembly and configured for manual actuation to drive the drive assembly, a vacuum generator configured to generate vacuum to suction cut tissue through the inner cutting shaft and into the vacuum generator, and a tissue collection cartridge configured to engage the housing. The tissue collection cartridge defines a port configured to communicate with the vacuum generator such that the vacuum generator urges cut tissue from the vacuum generator through the port into the tissue collection cartridge. An auxiliary vacuum source is configured to selectively provide additional vacuum to increase suctioning of cut tissue through the inner cutting shaft and into the vacuum generator.

  • Patent number: 11383720
    Abstract: Disclosed are a vehicle control method and an intelligent computing device for controlling a vehicle. The processor can detect a gaze response speed of the driver by projecting a virtual object to an HUD when determining that the driver is in a drowsy state. The processor outputs a secondary warning and controls the vehicle to be driven in accordance with the secondary warning when the gaze response speed of the driver is less than a predetermined reference value. Accordingly, it is possible to reduce accidents that occur due to carelessness of drivers. Disclosed are a vehicle control method and an intelligent computing device for controlling a vehicle. The processor can detect a gaze response speed of the driver by projecting a virtual object to an HUD when determining that the driver is in a drowsy state.

  • Patent number: 11334803
    Abstract: This document describes a data processing system for processing a feature vector that comprises features (one or more) that are indicative of dyslexic behavior that are indicative of dyslexic behavior. The data processing system includes a feature classification engine that generates classification metrics for a feature vector. Machine learning logic is used to determine a classification metric for each feature. Features that have a classification metric below a pre-determined threshold are removed. The data processing system includes a prediction engine that generates a prediction value indicative of a predicted likelihood of dyslexia. The prediction engine assigns, to each remaining feature, based on the classification metric of the respective remaining feature, a prediction weight and determines the prediction value based on the prediction weights.

  • Patent number: 11318949
    Abstract: Disclosed techniques include in-vehicle drowsiness analysis using blink-rate. Video of an individual is obtained within a vehicle using an image capture device. The video is analyzed using one or more processors to detect a blink event based on a classifier for a blink that was determined. Using temporal analysis, the blink event is determined by identifying that eyes of the individual are closed for a frame in the video. Using the blink event and one or more other blink events, blink-rate information is determined using the one or more processors. Based on the blink-rate information, a drowsiness metric is calculated using the one or more processors. The vehicle is manipulated based on the drowsiness metric. A blink duration of the individual for the blink event is evaluated. The blink-rate information is compensated. The compensating is based on demographic information for the individual.
