Abstract: A wireless ultrasound sensor 404 for non-destructive testing of a test object 502, the sensor comprising: an ultrasound transducer 406; a first induction coil 408, electrically coupled to the ultrasound transducer; a second induction coil 414, electrically coupled in parallel with the first induction coil; wherein the first and second induction coils are arranged to enable the transducer to be inductively operated by a remote device 504; and wherein the diameter of the second induction coil is greater than the diameter of the first induction coil.

Abstract: A fiber optical connector assembly with a crimp tube assembly improves tensile load on the optical fiber cable or microduct jacket when the connector assembly is used as part of an optical network that is secured between towers spaced apart 1,000 meters or more. The crimp tube assembly has one or more crimp zones, and the crimp tube assembly has a lip formed on an inner surface of the crimp right assembly to improve tensile strength when the crimp tube assembly is secured to a back post of a first fiber optic connector assembly that is air blown or push through a duct or conduit. An epoxy resin may be injected into a cavity between the cable jacket and the crimp tube assembly to improve tensile load strength.

Abstract: Provided is a sensor system which can detect a thickness reduction, a crack, or the like of a pipe or a container covered with a thick coating member through ultrasonic inspection without attachment and detachment of the coating member. A sensor system used for nondestructive inspection includes a sensor attached to a surface of an inspection target, a sensor coil that is electrically connected to the sensor via a first cable, a first electromagnetic wave blocking member that is disposed between the surface of the inspection target and the sensor coil, a sensor side coil that is disposed to face the sensor coil with a gap and is coupled to the sensor coil through electromagnetic induction, and a probe side coil that is disposed to be separated from the sensor side coil and is electrically connected to the sensor side coil via a second cable.
