  • Patent number: 11860764
    Abstract: A method, an apparatus, and a system are for evaluating code design quality. The method for evaluating code design quality includes: determining, based upon a result from static scanning of code, a probability of the presence of an error-prone pattern in the code; inputting the probability into an artificial neural network, and determining, based upon the artificial neural network, a prediction result for whether the code violates a preset design rule and for a quantized degree to which the design rule is violated; and based upon the prediction result, evaluating the design quality of the code. The present method is able to improve the accuracy of code design quality evaluation. By detecting a presence of an error-prone pattern in the code, whether or not a key design rule has been violated in a design process and a quantized degree to which the key design rule is violated are predicted.

  • Patent number: 11844948
    Abstract: Provided is an accurate, fast and long-term stable fused CRAP. The electrode includes a positioning anchor, a silicone catheter, a sensor compartment and a connecting wire. The method monitors physiological information such as blood PPG, blood oxygen saturation, temperature and impedance of blood in the right ventricular cavity, and monitors blood temperature information, which is also a slowly changing metabolic rate, to provide cross-comparison with blood oxygen saturation information, improving monitoring accuracy of blood oxygen saturation. The rapidly changing right ventricular apical impedance information is monitored to improve rapid response ability of CRAP. The LEDs driving current is dynamically adjusted by monitoring the internal temperature of the PPG sensor and the impedance change of the attached biological tissue, which indirectly reflects thickness change of the attached biological tissue, thereby delaying the failure time of the PPG sensor.

  • Patent number: 11571133
    Abstract: Technologies for monitoring a health-risk condition of a user include a virtual reality compute device having one or more near infrared (NIR) sensors. The virtual reality compute device presents a virtual reality (VR) presentation to the user. The virtual reality compute device produces sensor data through the one or more NIR sensors that is indicative of a heart rate of the user and a blood pressure of the user while the VR presentation is presented to the user. The virtual reality compute device determines whether the user is in a health-risk condition based on a comparison of the heart rate of the user to a heart rate safety threshold and a comparison of the blood pressure of the user to a blood pressure safety threshold. The virtual reality compute device performs a health-risk condition response in response to a determination that the user is in the health-risk condition.
