Abstract: An apparatus determining network health in a network comprising base station transceivers in bidirectional communication with radios, each having an identifier and transmitting a signal including the identifier. First and second devices each receive the transmitted signal during normal over-the-air operation of the radio, measure signal parameters, and determine operating characteristics of the radio from the parameters. Each of the devices produce a responsive received signal when the first operating characteristics determined by the first device indicate a healthy first radio and the second device produces a responsive received signal when the second operating characteristics determined by the second device indicate a healthy first radio. The devices determine respective signal parameters of the respective received signals. The received signals are time aligned to insure that the devices have determined the respective signal parameters of the same transmitted signal.

Abstract: A method for controlling state dependent behaviors of a user includes obtaining biometric data from a user. The method involves converting at least some of the biometric data into lines of sounds. The method involves compiling at least some of sound into a composition or song arranged to represent a targeted state. The method involves feeding the composition or song back to the user to induce the user to the targeted state.

Abstract: A gearbox for driving a sprocket includes a gear train and an output shaft assembly positioned between the gear train and a power output end of the gearbox. The output shaft assembly includes, a first shaft segment extending to the power output a second shaft segment coupled to the gear train and a torsion spring interposed between the first shaft segment and the second shaft segment. Upon non-conjugate meshing of the sprocket, the torsion spring expands and contracts so that the angular velocity of the second shaft segment differs from the angular velocity of the first shaft segment.

Abstract: Aspects of the subject disclosure are directed towards providing feedback to users of multi-user system that has biometric recognition capabilities, so that a user knows whether the system has correctly associated the user with his or her identity. The feedback may include a display of a current camera view, along with visible identity information that is associated with each user in the view. The feedback may include per-user icons (e.g., tiles, thumbnail images and so on) by which a user visually confirms that he or she is correctly recognized. Any misrecognition may be detected via the feedback and corrected. Feedback may convey other information, such as the current interaction state/capabilities of a user.
