Abstract: The assisted navigation system is intended to enable an assisted operation mode in ground mobile robots. The system is designed to achieve an autonomous relocation of a robot from one location to another location within a sidewalk, minimizing the need for constant human intervention. The system includes a camera for collecting the visual data needed to assess the terrain and potential obstacles, a collection of sensors to detect potential obstacles during assisted operations, a communication module to receive inputs from a remote operator to enable the activation of this system, a localization module for teleoperations, a local server module to store the information gathered, a processor configured to operate a robot in an assisted mode of operation based on input from the communication interface in which the robot performs a task without human intervention, and a communication interface coupled to the processor and configured to communicate control values to the systems of the mobile robot.

Abstract: A system and method involves detecting a trigger event during operation of an autonomous ground vehicle traveling between two physical locations; generating event sequence data from primary sensor data, secondary sensor data, spatiotemporal data, and telemetry data through operation of a reporter; communicating the event sequence data to cloud storage and raw data to a streaming database; transforming the raw data into normalized data stored in a relational database through operation of a normalizer; operating a curation system to identify true trigger events from the normalized data and extract training data by way of a discriminator; operating a machine learning model within an active learning pipeline to generate a model update from aggregate training data generated from the training data by an aggregator; and reconfiguring the navigational control system with the model update communicated from the active learning pipeline to the autonomous ground vehicle.

Abstract: A frequency division multiplexing system includes a processor, a first digital to analog converter (DAC) for generating a local oscillator signal, a second DAC for generating a chirp signal, and a plurality of electronic elements, each having a transmit signal mixer for combining the local oscillator and chirp signals, and a transceiver configured to transmit the combined local oscillator and chirp signals, where the processor may be configured to operate the first DAC and second DAC to vary frequencies of the local oscillator and chirp signals such that the combination of the local oscillator and chirp signals results in a constant center frequency with a varying phase.

Abstract: A composition directed to comprising from about 25% to about 60% a pyrithione or polyvalent metal salt of a pyrithione; from about 0.01 to about 1% of a cationic polymer; from about 0.01% to about 2.0% of an anionic surfactant wherein the cationic polymer has a molecular weight from about 100,000 to about 2,000,000.
