Publication number: 20230274538Abstract: A framework for a few-shot learning method is disclosed. In a first part, self-supervision and classification supervision are used to train a feature extractor. An example self-supervision method comprises running grayscale images through an edge filter, normalizing the filtered images, setting the normalized images to ground truth, generating feature-extracted images, using a decoder to reconstruct images from the feature-extracted images, determining a loss between the reconstructed images and the ground truth images, and using the loss to update parameters of the feature extractor. In a second part, a few-shot adaptation process is performed to adapt the model to a novel rapid test kit.Type: ApplicationFiled: March 23, 2023Publication date: August 31, 2023Applicant: The Trustees of Columbia University in the City of New YorkInventors: Samuel K. SIA, Shih-Fu CHANG, Siddarth ARUMUGAM, Uzay MACAR, Jiawei MA, Guangxing HAN, David COLBURN

Publication number: 20210378529Abstract: The disclosed subject matter includes a wearable device for blood pressure monitoring. The embodiments employ a set of sensors to calculate a relative external pressure. A transmural pressure error can be calculated based on the relative external pressure. A measured transmural pressure can be corrected based on the transmural pressure error. Some embodiments track altitude to calculate relative external pressure error. Some embodiments track arm orientation to calculate relative external pressure error.Type: ApplicationFiled: August 12, 2021Publication date: December 9, 2021Applicant: The Trustees of Columbia University in the City of New YorkInventors: David COLBURN, Samuel K. SIA

Publication number: 20080040675Abstract: A user interface on a display enables user perception of information regarding a communications session that leverages an instant messaging platform. The user interface includes an instant messaging application user interface and one or more tear-off elements corresponding to ongoing instant messaging communications sessions. Each tear-off element is configured to enable perception and selection by a user of a corresponding instant messaging communications session. Also, each tear-off element is configured to be independently visually separated from other elements of the instant messaging application user interface and maintained as a separate entity on the instant messaging application user interface.Type: ApplicationFiled: October 15, 2007Publication date: February 14, 2008Applicant: AOL LLCInventors: James Canfield, Kenneth Carbone, David Colburn, Linda Myers, Thomas Van Lenten, Gregory Willis
