Abstract: The present invention relates to an inverter topology with a DC/DC voltage boost converter, which is also scalable. The arrangement of converters and power lines used in this topology makes it possible to maximize the efficiency of the energy conversion that takes place in photovoltaic plants or in any other system based on power transmission that use DC power lines, reducing the values of current used for a given power level. The inverter includes two DC/DC converters connected in parallel to one another and two DC/AC converters connected in parallel to one another. The two DC/DC converters are connected in series with the two DC/AC converters by means of two buses consisting of three DC power lines where one of the DC power lines is common to the two buses.

Abstract: A synergistic bactericide and bacteriostatic organic sanitizing/disinfectant/cleaning formulation of acetic acid and propionic acid or salts thereof, having a ratio acetate (A): propionate (P) from 4:100 to 20:1, dissolved in water and diluted as required, to a final concentration in the range of 0.5% w/v to 50% w/v of the mixture in the formulation. Particularly, the present formulation comprising 0.03-15% w/v of acetate buffer and 0.04-17.50% w/v and a q.s.p filtered drinking water, pH 5-6 to be used to the food industry as a Generally Recognized as Safe Compound (GRAS), and having a significantly increased sanitizing and sterilization effect on food as well inert hard, semi-hard and soft surfaces, being safe, environmentally friendly, of broad-spectrum and high efficiency. Such foods can be selected from harvested or fresh fruits and vegetables.

Abstract: An additive manufacturing system comprises a build plane and an energy source configured to direct energy onto a work region of the build plane. An optical detector is configured to receive one or more optical signals from the work region. An optical filter is positioned between the work region and the optical detector, wherein the optical filter includes a first partially transmissive polarized filter having a first polarization axis and a second partially transmissive polarized filter having a second polarization axis. The first polarization axis is rotationally offset from the second polarization axis approximately 90 degrees. The optical filter improves the signal to noise ratio of the optical sensors.

Abstract: Arrangement and method for managing set-top boxes used by customers of a content service provider includes at least one automated tester each arranged to couple to set-top boxes and subject each set-top box to a series of automated tests to determine whether each set-top box is functioning properly or requires subsequent repair, and a processor unit coupled to each automated tester for receiving test results therefrom and monitoring testing of set-top boxes via the automated tester(s). Each automated tester is located at a testing facility maintained by the content service provider. A database stores the test results from the automated tester(s) and enables generation of customized reports about the set-top boxes tested by the automated tester(s). A billing system is coupled to each automated tester and to the processor unit and coordinates invoicing for testing performed by the automated tester(s) and repair of set-top boxes at a repair facility.
