Abstract: A method of providing vehicle diagnostics may include receiving a first communication from a user, processing the first communication using a natural language processing (NLP) model to produce NLP model output including a sequence of words, extracting one or more keywords from the sequence of words, and instructing a data acquisition and transfer device (DAT) connected to an OBD port of a vehicle to perform a selected function based on the one or more keywords. The method may further include receiving diagnostic data from the DAT, the diagnostic data having been retrieved from the vehicle by the DAT in accordance with the selected function, and determining a diagnostic condition of the vehicle based on the diagnostic data.

Abstract: In at least one aspect, a small satellite includes a cylindrical body, a predetermined payload volume, a payload adapter ring mechanical interface for interchangeably mechanically coupling to a launch vehicle payload adapter ring, an electrical interface specifying a set of electrical specifications for interchangeably electrically coupling to the launch vehicle payload adapter ring, a specified center of gravity location and specified frequency response, where the predetermined payload volume, payload adapter ring mechanical interface, electrical interface, specified center of gravity location, and frequency response range allow the small satellite to be interchanged with other small satellites when coupling to the launch vehicle.
