Abstract: A crimper for altering an implantable medical device from an uncompressed state to a compressed state. The crimper includes a plurality of crimper elements that define a crimper channel, each of the crimper elements including a non-planar surface that forms a portion of the crimper channel. Each non-planar surface is configured to apply non-uniform radial compression along a length of the implantable medical device during operation of the crimper when altering the implantable medical device from the uncompressed state to the compressed state. The crimper also includes handle configured to operate the crimper. Actuation of the handle decreases a volume of the crimper chamber to transition the implantable medical device from the uncompressed state to the compressed state.

Abstract: A method, device, and system for detecting a current leak in a traction power rail. Magnetic or electrical properties of the rail are measured. The measurements are performed using a rail instrument that senses the properties around the rail at various times while the instrument is being moved down the rail, such as using a cart or train. The rail instrument may be a flux concentrator or open Rogowski coil. The locations of the rail, about which the readings are taken by the rail instrument, may be determined and correlated with the measurements themselves. The method may comprise measuring the magnetic field of the rail along a length of the rail, and identifying a leak based on differences between the magnetic field measurements. The system may comprise a cart comprising the rail instrument and a location instrument.

Abstract: An in-flight contact charging system includes a charging contact, a power receiver, and a recharging controller connected to the charging contact. The charging contact is mounted on a support. The power receiver is mounted on an aerial vehicle containing an electrical load. The power receiver connects to the electrical load. The recharging controller can detect contact between the charging contact and the power receiver; transmit electricity to the charging contact; detect a spike in battery impedance; and discontinue transmission of electricity to the charging contact. The system enables a drone to rapidly recharge its battery while in flight by making brief contact between the charging contact and the power receiver. This system keeps the drone airborne, does not waste energy, and is comparatively cheap to build and maintain.

Abstract: Audio/speech-based and text-based interactions between a transaction terminal and a user conducting a transaction are provided. In an embodiment, the terminal may establish a direct wireless connection to a user-operated device or an indirection wireless connection to the user-operated device through a proxy device. In an embodiment, the wireless connection is automatically established through a different out-of-band wireless communication between the terminal and the user-operated device. In an embodiment, text-based data for the transaction are provided over a second simultaneous wireless connection that is different from the wireless connection associated with providing the audio/speech data. In an embodiment, audio/speech data provided from the user during the transaction are enhanced for security and are filtered for accuracy using audio-based processing and/or image-based processing. In an embodiment, a speech-to-text and text-to-speech interface for a transaction at the terminal is provided.

Abstract: Methods for the synthesis of graphene, and more particularly the method of synthesizing graphene by flash Joule heating (FJH). Such methods can be used to synthesize turbostratic graphene (including low-defect turbostratic graphene) in bulk quantities. Such methods can further be used to synthesize composite materials and 2D materials.

Abstract: The present disclosure relates to a radiation detection vehicle with a directional radiation detection system.
