In certain embodiments of the present disclosure relate to a method for detecting liveness of a user during biometric authentication. The method comprising identifying a speech signal in a pre-determined time interval associated with the speech signal. Furthermore, the method comprising determining a speech respiration co-occurrence (SRC) score associated with the speech signal. In addition, the method comprising detecting liveness of the user, if the SRC score is above a predefined threshold, wherein the detection of liveness further aids in increasing the security of biometric authentication system.

Disclosed is an automatic depression detection method using audio-video, including: acquiring original data containing two modalities of long-term audio file and long-term video file from an audio-video file; dividing the long-term audio file into several audio segments, and meanwhile dividing the long-term video file into a plurality of video segments; inputting each audio segment/each video segment into an audio feature extraction network/a video feature extraction network to obtain in-depth audio features/in-depth video features; calculating the in-depth audio features and the in-depth video features by using multi-head attention mechanism so as to obtain attention audio features and attention video features; aggregating the attention audio features and the attention video features into audio-video features; and inputting the audio-video features into a decision network to predict a depression level of an individual in the audio-video file.

The invention provides a piezoresistive electronic skin, a preparation method and a use thereof. The piezoresistive electronic skin uses carbon nanotube film as the conductive layer and uses materials provided with micro-nano patterns, such as polydimethylsiloxane, polyethylene terephthalate, polyvinyl alcohol, polyvinyl formal, polyethylene, and so on, as the substrate, enabling the substrate has advantages of high flexibility and being pliable, and it needs low operating voltage and little power consumption, but has high sensitivity and short response time. More importantly, the invention uses the patterned flexible substrate as the basis, greatly improving the sensitivity of electronic skin reacting to tiny applied force from outside. The invention also provides a capacitive electronic skin and a preparation method thereof. Further, the invention also provides a use of the piezoresistive electronic skin or the capacitive electronic skin on speech recognition, pulse detection, medical robot, etc.

A non-transitory computer-readable storage medium storing a set of instructions executable by a processor. The set of instructions is operable to receive a set of data relating to a current symptom of a patient; determine one of a current level of breathlessness and a current level of edema for the patient based on the received data; and provide an alert to one of the patient and a medical professional, if the determined one of the current level of breathlessness and the current level of edema is greater than an acceptable level.

A system and a method for generating stress level information for an individual and stress level resilience information for an individual, which includes a stress information processing module configured to process stress information for the individual, the stress information for the individual comprising at least two of psychometric information for the individual, physiological information for the individual, behavioural information for the individual, and cognitive function information for the individual.

A system for determining biological information of a subject includes a surface configured to display an image of a subject positioned in front of the surface, a sensor configured to identify data of the subject, and an analysis and control unit configured to analyse the data and determine biological information of the subject based on the data.

Information about a device may be emotively conveyed to a user of the device. Input indicative of an operating state of the device may be received. The input may be transformed into data representing a simulated emotional state. Data representing an avatar that expresses the simulated emotional state may be generated and displayed. A query from the user regarding the simulated emotional state expressed by the avatar may be received. The query may be responded to.

Disclosed is a 2D scanning videokymography system for analyzing a vibration of vocal-fold mucosa, including: a laryngoscope for observing vocal folds; a light source for illuminating the vocal folds; a video camera for recording and storing images observed through the laryngoscope; a computer incorporating an image capture unit for converting a video signal transmitted from the video camera into a digital image signal, a storage unit for storing the digital image signal, a control unit for analyzing the image signal of the storage unit and displaying the analysis results on a monitor, and analysis software for analyzing the image signal of the storage unit; and a monitor for displaying a captured image and analysis results.

A system and a method for assessing a condition in a subject. Phones from speech of the subject are recognized, one or more prosodic or speech-excitation-source features of the phones are extracted, and an assessment of a condition of the subject, is generated based on a correlation between the features of the phones and the condition.

The present invention relates to a system (10) for assessing eyesight acuity of a subject (20), comprising: a display (12) for displaying graphics and/or text to the subject (20); an eye movement sensor (14, 14′) for monitoring an eye movement of the subject (20) while the subject (20) is watching the graphics and/or text displayed on the display (12); a processing unit (16) for assessing the eyesight acuity of the subject (20) based on an analysis of the monitored eye movement, wherein the analysis of the monitored eye movement includes an analysis of at least one of a duration of eye saccades, a frequency of eye saccades, a duration of eye fixations and a frequency of eye fixations in the monitored eye movement; and an output unit (18, 18′) for indicating the result of the assessment of the eyesight acuity. The present invention furthermore relates to a system (110) for assessing hearing ability of a subject (20).
