Patent number: 11992316Abstract: This disclosure relates generally to a method and system for assessment of sustained visual attention of a target. The conventional methods utilize various markers for assessment of attention, however, blink rate variability (BRV) series signal is not explored yet. In an embodiment, the disclosed method utilizes BRV series signal for assessing sustained visual attention of a target. A gaze data of the target is recorded using an eye tracker and a set of uniformly sampled BRV series signal is reconstructed from each of the BRV series. One or more frequency domain features, including pareto frequency, are extracted from the set of uniformly sampled BRV series signal. The values of frequency domain features extracted from the set of BRV series signals are compared with corresponding threshold values to determine visual sustained attention of the target.Type: GrantFiled: March 26, 2021Date of Patent: May 28, 2024Assignee: TATA CONSULTANCY SERVICES LIMITEDInventors: Rahul Dasharath Gavas, Mithun Basaralu Sheshachala, Debatri Chatterjee, Ramesh Kumar Ramakrishnan, Venkata Subramanian Viraraghavan, Achanna Anil Kumar, Girish Mariswamy Chandra

Patent number: 11996118Abstract: An important task in several wellness applications is detection of emotional valence from speech. Two types of features of speech signals are used to detect valence: acoustic features and text features. Acoustic features are derived from short frames of speech, while text features are derived from the text transcription. Present disclosure provides systems and methods that determine the effect of text on acoustic features. Acoustic features of speech segments carrying emotion words are to be treated differently from other segments that do not carry such words. Only specific speech segments of the input speech signal are considered based on a dictionary specific to a language to assess emotional valence. A model trained (or trained classifier) for specific language either by including the acoustic features of the emotion related words or by omitting it is used by the system for determining emotional valence in an input speech signal.Type: GrantFiled: October 19, 2021Date of Patent: May 28, 2024Assignee: TATA CONSULTANCY SERVICES LIMITEDInventors: Ramesh Kumar Ramakrishnan, Venkata Subramanian Viraraghavan, Rahul Dasharath Gavas, Sachin Patel, Gauri Deshpande

Publication number: 20240104377Abstract: This disclosure relates generally to the field of Electroencephalogram (EEG) classification, and, more particularly, to method and system for EEG motor imagery classification. Existing deep learning works employ the sensor-space for EEG graph representations wherein the channels of the EEG are considered as nodes and connection between the nodes are either predefined or are based on certain heuristics. However, these representations are ineffective and fail to accurately capture the underlying brain's functional networks. Embodiments of present disclosure provide a method of training a weighted adjacency matrix and a Graph Neural Network (GNN) to accurately represent the EEG signals. The method also trains a graph, a node, and an edge classifier to perform graph classification (i.e. motor imagery classification), node and edge classification. Thus, representations generated by the GNN can be additionally used for node and edge classification unlike state of the art methods.Type: ApplicationFiled: June 14, 2023Publication date: March 28, 2024Applicant: Tata Consultancy Services LimitedInventors: JAYAVARDHANA RAMA GUBBI LAKSHMINARASIMHA, ADARSH ANAND, KARTIK MURALIDHARAN, ARPAN PAL, VIVEK BANGALORE SAMPATHKUMAR, RAMESH KUMAR RAMAKRISHNAN

Publication number: 20240013918Abstract: The present invention relates to a method and system for early detection of COVID-19. Existing methods require data from multiple sensors for training a prediction model whose output is considered as final prediction which is actually the prediction for a particular day or time instance. However, this prediction doesn't detect actual infection of COVID-19 since it requires monitoring the change in health of the user over consecutive days. Embodiments of present disclosure overcome these challenges by a prediction model for COVID-19 which requires only data from Photoplethysmography (PPG) sensor seamlessly collected from a wearable device still able to provide accurate COVID-19 prediction with application of a post processing technique on the predictions of the prediction model. Since COVID-19 symptoms have an effect on heartrate and oxygen saturation which are effectively captured by PPG sensor data, studying these dynamics during infection period gives insights to perform early detection of COVID-19.Type: ApplicationFiled: July 3, 2023Publication date: January 11, 2024Applicant: Tata Consultancy Services LimitedInventors: DIBYANSHU JAISWAL, SHAKIL AHMAD, MITHUN BASARALU SHESHACHALA, KARTIK MURALIDHARAN, ARPAN PAL, RAMESH KUMAR RAMAKRISHNAN, BALAKUMAR KANAGASABAPATHY, TANMAY ACHARIA, LOKNATH TIWARI, KAYAPANDA MANDANA
