The present disclosure illustrates a three-dimensional trace verification apparatus and method thereof. The three-dimensional trace verification apparatus includes a signal emitting module and a platform module configured to maintain a fixed relative location. When a motion trace of the platform module is different from a pre-recorded trace of a trace transmitting module, the trace transmitting outputs a deviation signal according to a sensed signal. This mechanism can achieve a technical effect of automatically verifying whether the motion trace of the platform module and the pre-record trace made by a user are the same, and recording the error.

A three-dimensional position information generation unit generates three-dimensional position information using measured data acquired by a measurement instrument. An additional information acquisition unit acquires, as additional information, at least any one of authenticated user information, instrument information, and measurement information. An information encryption unit encrypts a set of the generated three-dimensional position information and the acquired additional information.

A method for manufacturing a strain gauge device and a strain gauge device are presented. The method includes obtaining a first substrate, preferably a first formable substrate film for accommodating electronic components, printing by a printed electronics method, such as by screen printing or inkjet printing, a strain gauge on the first substrate, and molding, preferably by utilizing injection molding, a molded material layer embedding the strain gauge.

A narrowband transmission system includes a dielectric grating that defines a surface and includes a plurality of longitudinal members arranged along an axis. The longitudinal members are surrounded by a medium. The longitudinal members are made of a material that has an index of refraction that is greater than an index of refraction of the medium. The dielectric grating is configured to receive radiation at the surface. The system further includes a means for breaking a symmetry between the radiation and the dielectric grating such that the dielectric grating transmits a given wavelength band of the radiation through the dielectric grating while rejecting remainder of wavelengths embodied in the radiation.

An automatic surface elevation table (Auto SET) for measuring ground surface movements and land surface subsidence. The Auto SET includes a free-floating foot resting on a sediment surface. A benchmark rod passes through a center of the free-floating foot, and is driven into the sediment surface and extends above the sediment surface. A water level recorder system is attached to the benchmark rod. The water level recorder system includes a water level recorder attached to a top of the benchmark rod, a double block pulley system having an upper end connected to the water level recorder and a lower end connected to the free-floating foot, and a counterweight attached to the upper end of the double block pulley system. The water level recorder system measures movement of the free-floating foot to determine ground surface movements.
