| 20080266025 | Power line communications device with auxiliary filtered power output - A power line communications device with auxiliary filtered power output is disclosed which permits the coverage of a power line communications, PLC, system to be widely extended by means of using a high-impedance filter integrated into the actual communications equipment, in such a way that avoids the problems inherent to the use of PLC technology in an adverse environment such as that which results from connection of electrical apparatus in the same socket as power line communications equipment. | 10-30-2008 |
| 20090002047 | Switching Circuit Which Is Used To Obtain A Doubled Dynamic Range - It permits switching signals with a peak level equal to the source voltage by means of a transistor, the peak to peak level being double the source. | 01-01-2009 |
| 20090141821 | PROCEDURE FOR SIMULTANEOUS TRANSMISSION IN TIME AND FREQUENCY OF MULTIPLE COMMUNICATIONS OF DATA BY MEANS OF OFDM MODULATIONS - Which permits to solve the problems relating to the interference produced among communications equipment of the same technology but belonging to different communications and which simultaneously use the same communications channel in time and frequency. It comprises modifying one of the parameters of the starting signal. The main advantage of the invention is that, in a simple way, it allows equipment to be correctly synchronised with the signals reaching it from its own network while ignoring signals of lesser power received from other networks using the same or different technology, without any need to carry out a complex and costly processing on reception. | 06-04-2009 |
| 20100102900 | PROCESS FOR REDUCTION OF THE COMMON MODE CURRENT FOR POWER LINE COMMUNICATIONS EQUIPMENT - It permits common mode currents to be reduced in communications equipment using the mains network as transmission medium, in order to adapt the emission values of common mode to standards on power line communications corresponding to each country. | 04-29-2010 |
| 20100233954 | SINGLE-PORT SIGNAL REPEATER - Single-port signal repeater. The repeater is connected in parallel to the communication means ( | 09-16-2010 |
| 20100264886 | DEVICE FOR VOLTAGE MULTI-INJECTION ON MULTIPLE CONDUCTORS - Which permits the application of methods for increasing the performance of a communications system on a medium made up of N conductors ( | 10-21-2010 |
| 20100289595 | DEVICE FOR INDUCTIVE MULTI-INJECTION ON MULTIPLE CONDUCTORS - Which permits the application of methods for increasing the performance of a communications system on a medium made up of N conductors ( | 11-18-2010 |
| 20110109399 | DEVICE FOR INDUCTIVE MULTI-INJECTION ON MULTIPLE CONDUCTORS - The techniques described herein permit the application of methods for increasing the performance of a communications system on a medium made up of N conductors ( | 05-12-2011 |
