Patent number: 11883186Abstract: Computer-assisted methods for assisting in anomaly identification relating to a dysmorphology analysis comprise retrieving and/or generating a sequence of progressively changing images that depict morphing of at least a subject's first physical feature, between at least a first state representing an identification of a first anomaly relating to a dysmorphology and a second state representing lack of the identification of the first anomaly. The number of images in the sequence is selected to provide a substantially continuous transition between the first and second states. The retrieved and/or generated images are displayed on a display of a processing device, and a user interface on the processing device is provided for a user to make an image selection, which can then be used to determine identification or lack of identification of the anomaly.Type: GrantFiled: March 6, 2020Date of Patent: January 30, 2024Assignees: San Diego State University (SDSU) Foundation, BLUE RESONANCE, LLCInventors: Edward Riley, Ganapathy Chockalingam

Intelligent high-speed unmanned vehicle communications via bio-inspired multi-beam pipe transmission
Patent number: 10686691Abstract: Disclosed and described herein are smart, high-speed UV communication protocols, inspired by the biological principles. The disclosed and described protocols use a ‘pipe’ routing topology to deliver large amount of data among the UVs equipped with multi-beam antennas.
