Abstract: A technology is described for optical communication. An example of the technology can include receiving an event stream containing indications of independent events detected by pixels in an event camera. An event may be a change in brightness detected by a pixel in the pixel array, and the pixel independently generates an indication of the event in response to detecting the event. The event stream can be demultiplexed into a plurality of communication streams containing related events associated with a plurality of communication sources. The events contained in a communication stream can be aggregated based in part on an event proximity and an event time that associates an event with other events contained in the event stream. The plurality of communication streams can be demodulated to extract optically transmitted information from the plurality of communication streams, which can be sent to a data consumer.

Abstract: A system and method for detecting Trojans and other intermittent severe defects in a digital circuit design. A simulation of the digital circuit design results in a value change dump file, which is compiled to form a value change summary file containing counts of the numbers of value changes for the signals in the digital circuit design. A discriminative neural network analyzes the value change summary file to determine whether an intermittent severe defect is present. A corpus of digital circuit designs, with and without intermittent severe defects, is used to train the discriminative neural network. The training process may involve dimensionality reduction of the data, enlargement of the data set, and data compression using an autoencoder.

Abstract: A system and method for determining positional order of vehicles across a threshold plane within a dynamic environment is provided. The system can include moving vehicles (e.g., boats) each having a GPS receiver. A reference object (e.g., an anchored boat) can have an image capturing device and a primary GPS receiver, and can be subject to movement induced by the dynamic environment. A fixed object having a known position (e.g., a government buoy) relative to the reference object define a threshold plane, which is subject to movement based on movement of the reference object. Photometric data gathered by the image capturing device and geospatial data gathered from the GPS receivers, the primary GPS receiver, and the fixed object is analyzed by a processor to determine a positional order at which each vehicle crossed the movable threshold plane.
