Abstract: A laser putting device for a golf putter includes a guiding unit for generating a laser beam, a frame for supporting the guiding unit disposed in the frame, an activator connected to the golf putter and communicated with the guiding unit for turning the guiding unit between on and off positions thereby generating the laser beam. A bracket of the laser guiding device is adaptable to receive a tubular member of the guiding unit that has a mirror and a diode emitting the laser beam and guiding the laser beam into the mirror angled in the fashion to form the laser beam having 90 degrees thereby allowing the golfer to point the laser beam at the target point, such as a hole in a golf green. The laser guiding device help the golfer to learn how to improve a strike and place the golf ball into a hole within short period of time and without necessity of using outdoor facility.

Abstract: The present invention is a method and an eddy current system for non-contact determination of the resistance between the current lead stripe and the coating during continuous fabrication of chemical power sources such as batteries, supercapacitors, photovoltaic modules and the like. Both the method and the non-destructive test system for practicing the method are described. The method includes placing of an integrated measuring transducer containing two strap-type eddy current probes above the surface of the coating applied to the metallic current lead stripe in the region of the shaft guiding the stripe movement, so that all the points of the operating surface of the transducer being at an equal distance from the stripe surface coating so that the two probes would take measurements on the same area of the coating.

Abstract: The present invention is connected with the holographic interferometry method and device that provides, to a very high precision, the reconstructing the original waveform of light emitted or reflected by an object. This method allows image resolution close to that of the wavelength of the light being used. The non-destructive method of holographic interferometry coupled with impulse heating of the test article to allow observation of its dynamic response to operating conditions, as described herein, is one of the most effective non-contact automated quality control methods available.
