Systems and methods for using auditorily-induced vection (AIV) to enhance a person's attitude awareness are provided herein. In at least one embodiment, an auditory object is projected based on the orientation of the person or a vehicle and the projected auditory is provided to the person. By projecting the auditory object, the attitude of the person or the vehicle can be conveyed to the person to enhance the person's attitude awareness.

Systems and methods for enhancing attitude awareness in ambiguous environments

A technology is described for hyperspectral imaging. An example of the technology can include receiving an event stream of events from an event camera coupled to an interferometer. The event camera can receive light output from the interferometer and generate the event stream, comprising event data that corresponds to the light output. The events in the event stream can indicate a pixel that detected an event, a time of the event, and a polarity of change in brightness detected by the pixel. Spectral data can be generated for the events in the event stream using a demodulation and frequency transform to convert temporospatial aggregates of events in the event stream to frequency domain data that corresponds to an optical spectrum. A hyperspectral image of an input scene in a spectral range can be generated using the spectral data.

A technology is described for pixel frequency filtering for event cameras. An example of the technology can include receiving events representative of changes in brightness detected by a pixel in a pixel array included in the event camera, tracking a number of event sign transitions that occur within a defined time window, determining that the number of event transitions corresponds to an event transition frequency, and allowing the events generated by the pixel to be output from the event camera.

Systems, devices, and methods for pixel frequency filtering for an event camera

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.

Systems and methods for enhancing attitude awareness in telepresence applications

Systems and methods for providing a user with enhanced attitude awareness

A body garment including sensors distributed throughout the garment, each sensor senses body state information from a local surface area of a body; and sensor nodes in proximity to the plurality of sensors, each sensor node including a processor to receive sensing body state information from at least one of the plurality of sensors. Each processor is configured to receive body state information locally from sensors, to utilize the information to determine a local surface shape of the surface of a portion of the body part; and to exchange local surface shape information with neighboring sensor nodes. At least one processor of utilizes the local surface shape information received from the sensor nodes to generate one overall model of a surface shape of the entire surface of the body part covered by the garment.

A system including an optical waveguide having a length extending from an optical interrogator at a first end, a plurality of light-modulating sensor nodes disposed at predetermined locations along the length of the optical waveguide, each of the plurality of light-modulating sensor nodes having an optical modulator for modulating an optical signal propagating from the optical interrogator in the optical waveguide, and for returning the modulated optical signal to the optical interrogator in an opposite direction along the same optical waveguide path.

Optical waveguide system for interrogating a plurality of sensor nodes wherein a location of the received input signal is determined

This invention relates to methods and systems for providing data from a distributed array. In one aspect, the array is a sensor array that includes sensor nodes that are each associated with one or more sensors, and the data includes sensor data acquired from the sensors by the sensor nodes. The sensor array employs modular and interchangeable sensor nodes that are capable of self-organizing in response to a network disruption while maintaining a flow of synchronized data to the event monitor. This self-organizing characteristic enables the overall network of nodes to be self-healing and easily extensible. The improved fault resilience makes it possible to deploy the sensors without requiring complex monitoring or fault diagnosis. Embodiments of the invention can be employed in any number of applications, including without limitation, tunnel activity detection, seismic/acoustic monitoring/detection and other applications where gathering sensor data may be desired.

Self-organizing extensible distributed sensor array architecture

The systems and methods described herein relate to an airborne shooter detection system having a plurality of sensors coupled to the body of an aircraft such as a helicopter. The system includes at least five sensors configured and arranged to disambiguate the location of a shooter. By measuring the arrival times of the shockwaves of projectiles at each of the sensors and determining the differences in the arrival times among sensors, the systems and methods may determine the location of one or more sources of the projectiles. A distance of at least ten meters separates two or more of the sensors. Such a separation is advantageous because it allows the system to disambiguate multiple shooters by resolving the curvature of the shockwave.
