The garment includes at least one of an inductive element and a capacitive element, and a controller identifies an inductance of the inductive element or a capacitance of the capacitive element, and determines a confidence level of information received from the sensing electrode based on the inductance or the capacitance. The wearable therapeutic device also includes an alarm module coupled with the controller and configured to provide a notification to a subject based on the confidence level. | 2020-12-24 |
20200397383 | SYSTEM AND METHOD FOR INTERFACING WITH BIOLOGICAL TISSUE - There is provided a system and method for interfacing with biological tissue. The system includes: a feature extraction module to implement an extraction approach to extract one or more features from the one or more physiological recording signals; a machine learning module to apply a machine learning model based on input data to detect a physiological event or condition for classification, the input data including the extracted features, the machine learning model trained using a training set including feature vectors of time-series data labelled with known occurrences of the physiological event or condition; and an output module to output the classification of the machine learning module. | 2020-12-24 |
20200397384 | PREDICTIVE KNEE JOINT LOADING SYSTEM - The present disclosure describes a system, method and software applications for predicting the KAM of a subject for a plurality of gait cycles of a subject. At least one sensor attachable adjacent to the ankle of at least one leg of the subject provides accelerometer and gyroscopic data for the plurality of gait cycles. A processing means receives subject parameters and accelerometer and gyroscopic data from the at least one sensor for evaluation by a neural network of predicted KAM values for the plurality of gait cycles of the subject. The neural network is configured via determining KAM values for each of the plurality of subjects from measurements during a plurality of gait cycles and other parameters. | 2020-12-24 |
20200397385 | MAGNETIC RESONANCE IMAGING APPARATUS - In one embodiment, a magnetic resonance imaging apparatus configured to sequentially execute plural imaging sequences includes: processing circuitry configured to calculate a predicted value of Long MR Examination specific absorbed energy which is an accumulated SAR (Specific Absorption Ratio) value over the plural imaging sequences; | 2020-12-24 |
20200397386 | PATIENT MONITOR - A patient monitor includes an acquiring section that acquires physiological information of a plurality of patients, a displaying section, a screen controller and an inputting section. The inputting section through which instructions for moving a display area for a patient are input. In accordance with instructions input through the inputting section, the screen controller executes one of processes of: interchanging a display area for a specific patient with a display area for another patient, and displaying a resulting image on the screen; deleting a display area for a specific patient from the screen; a process of moving a display area for a specific patient, and displaying a resulting image on the screen; and inserting a display area for a specific patient, and displaying a resulting image on the screen. | 2020-12-24 |
