| 20100141424 | ANTI-THEFT DEVICE FOR SOLAR PANELS - A theft protection device for photovoltaic solar panels is provided. The device includes of at least one cable which is made to pass through the solar panels. The cable can be fibre optic or electrical, and a light beam or an electrical current, respectively, is made to circulate through the cable. At the ends of the cable, an electrical control circuit is connected, capable of detecting a cut in the cable caused by the interruption of the light beam in the fibre or a voltage drop at the ends of the electrical cable. Cutting of the cable for theft of the solar panels is detected by the control circuit which activates an alarm, acoustic and/or visual, which can belong to the device or be remote. | 06-10-2010 |

| 20090316458 | SINGLE-PHASE INVERTER CIRCUIT TO CONDITION AND TRANSFORM DIRECT CURRENT ELECTRIC POWER INTO ALTERNATING CURRENT ELECTRIC POWER - The invention presents a structure for the conversion of direct current electric power into alternating current electric power, characterised in that it is simple, highly efficient and minimises the problem of electromagnetic compatibility. The circuit includes, in its first preferred embodiment, six switching elements governed by a command unit, four switches forming an H-bridge (T | 12-24-2009 |
| 20100127494 | PITCH CONTROL SYSTEM AND METHOD FOR WIND TURBINES - The present invention describes a pitch control system comprising a principal converter, and auxiliary converter, a direct current motor and a power storage system (accumulator) and has four different operation modes: normal, fault (first level), fault (second level) and emergency. In the case that a fault is detected, the system can move the motor in order to move the vanes to the desired position by making a controlled adjustment. | 05-27-2010 |
