Abstract: The proposed approach deals with efficient transmission for distributed AI with a provision to switch among multiple bandwidths. During the distributed inference at edge devices, each device needs to load part of the AI model only once, but the input/output features communicated between them can be flexibly configured depending on the available transmission bandwidth by enabling/disabling connection between nodes in the Dynamic feature size Switch (DySw). When some nodes are connected or disconnected in order to achieve the desired compression factor, other parameters of the DNN remain the same. That is, the same DNN model is used for different compression factors, and no new DNN model needs to be downloaded to adapt to the compression factor or the network bandwidth.

Abstract: An ultrasound probe is tested for failure of 5 elements of its array transducer by operating the probe with its lens in contact with the air. The echo signals produced during this mode of operation are beamformed into the usual set of scanlines produced by the probe. The frequency response of 10 each scanline is analyzed and compared with a reference signal of the frequency response of the corresponding scanline of a known good probe of the same type as the probe under test. If a comparison reveals a variance greater than a predetermined 15 deviation, the user is alerted that the probe should be replaced.

Abstract: The invention relates to a method for activating a terminal (4) by an operator, the activation of the terminal allowing secured exchanges of information between the terminal (4) and a secured server, characterized in that it comprises the following steps for the terminal (4): receiving from the operator (2) a first piece of activation information, receiving from an authorization server (3) a second piece of activation information, using the first and second pieces of activation information for activating the terminal.

Abstract: The putting practice aid mounts on the front face of the putter head and provides a horizontal arm extending in the opposite direction of the intended initial trajectory of the putted golf ball and a second arm perpendicular to the intended trajectory. When these arms are maintained parallel to the putting surface it assures that the golfer has positioned the shaft at the correct angle relative to the putting surface and that the golfer has correctly aimed the club. The putting practice aid may also comprise an observable coating on the surface of the indicator side of the attachment tab which facilitates establishment of a proper angle between the surface of the face of the putter head and the putting surface. The design of the putting aid allows for use with commercially available putters of varying loft and accommodates handedness preferences. The concepts included in the putting practice aid may be directly incorporated into a putter, which itself then becomes a putting training device.
