Abstract: A sterilizer for point-of-sale credit card readers and keypads. One or more UV-C LEDs are integrated into the housing of the unit and directed at the keypad or other surface. The LED lights shine on the keypad or other contact surfaces, such as a stylus. Because LEDs use low DC voltage, the electronics may be powered by the keypad device power supply. The electronic circuits may be designed so that the LEDs are automatically turned on after each transaction is complete for a predetermined amount of time to kill the vast majority of pathogens that could be transmitted from person to person. The LEDs may be arranged on both the left and right side of the keypad, and at the top edge of the keypad to illuminate all exposed surfaces of the keys.

Abstract: A method and apparatus to improve the speed of the free-form manufacture of complex systems uses the helical build process to 3D print or manufacture objects by using multiple material fusion sources simultaneously with single- or multi-flute helical build surfaces. As a result of the stationary material deposition line in a helical build machine, the speed of the fusion process can be improved by simultaneously using multiple fusion in sources in parallel on each fusion line. The geometry of the fixed location of the fusion line allows for changes in the optics of laser based machines which may lead to improvements in speed of over 100× compared to the speed of a single flute machines. Speed improvements are possible for all types additive manufacturing processes that use the helical build approach.
