Publication number: 20200237316Abstract: A computing device for use in a system for mapping brain activity of a subject includes a processor. The processor is programmed to select a plurality of measurements of brain activity that is representative of at least one parameter of a brain of the subject during a resting state. Moreover, the processor is programmed to compare at least one data point from each of the measurements with a corresponding data point from a previously acquired data set from at least one other subject. The processor is also programmed to produce at least one map for each of the measurements based on the comparison of the resting state data point and the corresponding previously acquired data point. The processor may also be programmed to categorize the brain activity in a plurality of networks in the brain based on the map.Type: ApplicationFiled: April 15, 2019Publication date: July 30, 2020Applicant: Washington UniversityInventors: Eric Leuthardt, Nicholas Szrama, Carl Hacker, Tim Laumann, Maurizio Corbetta, Abraham Z.

Publication number: 20200226239Abstract: Some embodiments include a messaging system capable of expression-based communication and/or expression-based actions. The messaging system can run on a computing device. For example, the messaging system monitors a camera feed from a camera of the computing device to detect a biometric signature when a messaging interface of the messaging application is actively being used. The messaging system can match the detected biometric signature against a known profile utilizing a facial recognition process to authenticate an operating user to use the messaging application. The messaging system can determine a human expression based on the detected biometric signature utilizing an expression recognition process to associate a contextual tag with an activity on the messaging interface. The messaging system can then communicate with a message server system to associate the contextual tag with content presented to the operating user or a conversation participated by the operating user via the messaging application.Type: ApplicationFiled: March 26, 2020Publication date: July 16, 2020Inventors: Eric Leuthardt, Scott Stern

Patent number: 10592650Abstract: Some embodiments include a method of providing security and privacy for a message sender. The method can include a messaging application determining that a messaging interface of the computing device is active and is revealing or about to reveal the electronic message. The messaging application can identify a recipient account of a messaging server system that is associated with the electronic message according to the electronic message or the messaging server system. The messaging application can then monitor a data feed from a sensor of the computing device to detect a biometric pattern that matches against a biometric profile model associated with the recipient account utilizing a biometric recognition process. In response to determining that the detected biometric pattern does not match the biometric profile model associated with the recipient account, the messaging application can activate a privacy shield to prevent content of the electronic message from being revealed.Type: GrantFiled: October 17, 2017Date of Patent: March 17, 2020Assignee: FaceToFace Biometrics, Inc.Inventors: Eric Leuthardt, Scott Stern

Patent number: 10300251Abstract: Drug delivery devices and methods are disclosed herein. In some embodiments, a drug can be delivered into a brain ventricle of a subject, where it can diffuse, flow, or otherwise travel across the ependyma and into the hippocampus. The drug can be delivered through a delivery device configured to selectively or transiently obstruct a portion of the ventricle, e.g., the temporal horn or a posterior portion of the temporal horn. The obstruction can define a partitioned volume of the ventricle, limiting or preventing flow of cerebrospinal fluid (CSF) into or out of the partitioned volume. Accordingly, a drug can be delivered into the partitioned volume without being diluted or carried away by CSF, allowing the drug to saturate the ependyma adjacent the hippocampus.Type: GrantFiled: June 2, 2017Date of Patent: May 28, 2019Assignee: Alcyone Lifesciences, Inc.Inventors: Eric Leuthardt, P J Anand
