Abstract: Techniques are described herein for managing transactions between data consumers and data providers using a blockchain. In some embodiments, a blockchain network receive smart contracts that govern access rights to data sets provided by blockchain members and smart contracts that execute blockchain transactions based on the usage of data sets. When a data set is provided to a blockchain member through the blockchain network, usage of the data set may be tracked. Responsive to detecting usage of the data set, one or more smart contracts may execute one or more blockchain transactions within the blockchain network.

Abstract: A vehicle monitoring device includes a camera or other optical sensor configured to be disposed at a trailing end of a first vehicle system. The camera or other optical sensor is configured to output one or more images or video of a field of view behind the first vehicle system. The monitoring device also includes a controller configured to receive output from one or more sensors and to activate the camera or other optical sensor to output the one or more images or video based on the output from the one or more sensors. The output from the one or more sensors indicates one or more of a change in movement of the first vehicle system, a temperature, an acoustic sound, or movement of a second vehicle system.

Each of the at least two wireless communication channels can operate at a different radio carrier frequency, and the first wireless transceiver may be part of a first vehicle. The method can also include transmitting, by the first wireless transceiver, common information in parallel on the at least two wireless communication channels to the second wireless transceiver and deactivating the at least two wireless communication channels.

Abstract: In one embodiment, a method for isolating and detection one or more biomarkers of interest on a dielectrophoresis device includes receiving a first biological sample containing one or more biomarkers of interest onto a dielectrophoresis (DEP) electrode array, applying a DEP force through particular electrodes of the DEP electrode array, wherein a strength, direction, and period of time of the DEP force is specific to the one or more biomarkers of interest of the first biological sample, and determining, via a digital sensor, a quantity of the one or more biomarkers of interest of the first biological sample.

Abstract: A method of supporting off-wing maintenance of an engine of a specific aircraft includes accessing flight data for a plurality of aircraft including measurements of properties from sensors or avionic systems, and maintenance data that indicates past maintenance or off-wing maintenance of a corresponding engine of each aircraft. A machine learning model is built to predict a life expectancy of the engine of the specific aircraft, measured to future off-wing maintenance of the engine, using a machine learning algorithm, and a set of features produced from selected properties. The machine learning model is built further using a training set produced from the set of features, the flight data including measurements of the selected properties, and the maintenance data. The machine learning model is then output for deployment to predict and thereby produce a prediction of the life expectancy of the engine of the specific aircraft from distinct flight data.

Abstract: A process receives, from a media content server, media content. Further, the process performs a first playback, with a processor at a media playback device, of one or more sample files corresponding to the media content. The one or more sample files each corresponds to a distinct codec format. In addition, the process determines, with the processor at the media playback device, a confidence score for each of the one or more sample files. The confidence score is associated with one or more factors indicative of the distinct codec format being software-based or hardware-based. Finally, the process performs a second playback, with the processor at the media playback device, of at least a substantial portion of the media content according to the distinct codec format that is hardware-based.

Abstract: A device and method for authenticating a user of a wearable biometric device. The method involves performing an initial biometric authentication of the user, the authentication being based on biometric features extracted from one or more image frames corresponding to a first portion of the user's hand and/or wrist, captured with a camera of a wearable device. A second part of the authentication method involves either re-confirming the initial biometric authentication of the user or verifying the liveness of the user or both re-confirming the authentication and verifying the liveness. The second step of the method is based on at least a measure of a second portion of the user's hand or wrist taken when the wearable device is worn against the user's hand or wrist. A notable part of the method is that the initial biometric authentication is performed by temporarily moving the camera away from the first portion of the user's hand and/or wrist.

Abstract: A biometric sensor apparatus for capturing patterns of blood vessels on the inner side of a wrist. The sensor apparatus has a strap with a near infrared camera mounted on a part of the strap. The camera is arranged for capturing an image of the blood vessels when it is temporarily held at an increased distance from the wrist than when the apparatus is simply being worn by the user. In some embodiments the camera is held at the required position for capturing the images of the blood vessels when the wrist strap is being opened or closed. In some embodiments the camera may be mounted in a deployant clasp of the wrist strap.
