Abstract: An ultrasonic device for scanning an object, the device having a collar configured for coupling to the object, the collar having an arcuate segment, a carriage coupled to the collar, the carriage configured for displacement along the arcuate segment, a ultrasonic probe unit coupled to the collar and comprising a wedge having a contoured face configured for maintaining conforming contact against a surface of the object, the ultrasonic probe unit configured to emit an ultrasonic beam for transmission through the contoured face of the wedge and into the object, and a position locator coupled to the carriage, the position locator configured to record a position of the ultrasonic probe unit.

Abstract: A ropeboard apparatus includes a ropeboard, and a support rope for hanging the ropeboard from an elevated structure. The ropeboard comprises an elongated platform having a longitudinal platform axis and a top surface shaped for a user to stand thereon, and a coupler for rotatably coupling the platform to the support rope so that the platform can be rotated about its longitudinal axis. The ropeboard apparatus may also include a spunk or universal joint for attaching the support rope to the structure, and a handle attached to the support rope at a location above the ropeboard. The coupler may comprise a shaft rigidly connected to the platform and oriented along the longitudinal axis, and a connector rotatably coupled to the shaft for connecting the platform to the support rope. The subject ropeboard apparatus is a new recreational and sporting apparatus that facilitates the performance of an extreme sport involving stunts and tricks.
