Abstract: THIS INVENTION RELATES TO A DEVICE FOR HARVESTING ENERGY FROM UBIQUITOUS RADIO WAVES AND MORE PARTICULARLY AN ADAPTIVE RECTIFIER DEVICE (8) DESIGNED AS POWER HARVESTING CIRCUIT WHICH IS TO HARVEST ELECTRICAL ENERGY BY TAPPING THE COMMERCIALLY AVAILABLE RADIO WAVES. THE DEVICE (10) COMPRISES OF AN ANTENNA (1), A HIGH FREQUENCY TRANSFORMER (2), AN AUTOMATIC TUNING CIRCUIT (3), A CAPACITORS BANK (4), A RECTIFIER (5), A THRESHOLD LIMIT CIRCUIT (6) AND AN ADAPTIVE CIRCUIT (7). THE THRESHOLD LIMIT CIRCUIT (6) IS CONFIGURED HAVING A PREDETERMINED OUTPUT VOLTAGE AND WHEN AN OUTPUT VOLTAGE IS BELOW THAN THE PREDETERMINED VOLTAGE, THE AUTOMATIC TUNING CIRCUIT (3) STARTS SEARCHING FOR NEW SOURCE OF RADIO FREQUENCY (RF) ENERGY BY CHANGING ITS CAPACITANCE BY FEEDING A DISTINCTIVE VOLTAGE INTO THE AUTOMATIC TUNING CIRCUIT (3) VIA THE ADAPTIVE CIRCUIT (7). THE SEARCHING FOR RF ENERGIES STOPS WHEN THE OUTPUT VOLTAGE LEVEL RESUMES TO THE PREDETERMINED VOLTAGE.

Abstract: THE PRESENT INVENTION IS A SENSING SYSTEM AND METHOD WITH SUBSTANTIALLY REDUCED OR ZERO LIGHT EFFECT. THE ARRANGEMENT OF THE SYSTEM OF THE PRESENT INVENTION COMPRISES TWO SENSORS (10, 20); WHEREBY AT LEAST ONE A FIRST SENSOR (20) IS CONFIGURED TO DETECT LIGHT AND ONE A SECOND SENSOR (10) IS CONFIGURED FOR MEASURING SAMPLES; AN ANALOG READ-OUT CIRCUITRY CONNECTED TO AT LEAST ONETHE SECOND SENSOR (10), AT LEAST ONE ADAPTIVE GAIN CONTROL MEANS (40) CONNECTED TO THE LIGHT SECOND SENSOR (20) FOR OPTIMIZING THE OUTPUT FROM THE LIGHT SECOND SENSOR (20); AND A DIFFERENTIAL AMPLIFIER (50); WHEREIN THE ADAPTIVE GAIN CONTROL MEANS (40) IS CONFIGURED TO OPTIMIZE THE OUTPUT FROM BOTH SENSORS (10, 20) FOR LIGHT COMPENSATION, BY WAY OF EQUALIZING THE LIGHT COEFFICIENT FACTOR (?, ?) BY BOTH SENSORS (10, 20). FIG 3

Abstract: 5 METHOD FOR DETERMINATION OF CHEMICAL IONS THE PRESENT INVENTION PROVIDES A METHOD FOR REDUCING AND/OR ELIMINATING SIGNAL INTERFERENCES FROM OTHER IONS WHICH ARE PRODUCED DURING DETECTION OF A PARTICULAR CHEMICAL ION IN A 10 SUBSTANCE, SAID METHOD COMPRISE OF AT LEAST TWO SENSORS (2,4) WHEREBY AT LEAST ONE SENSOR IS ASSIGNED TO COLLECT THE INTERFERING SIGNALS PRIOR TO THE ELIMINATION OF UNWANTED SIGNALS PROCESS. THE METHOD OF THE PRESENT INVENTION LEADS TO IMPROVED DETECTION OF THE DESIRED ION AND THUS PROVIDES REAL TIME 15 MONITORING OF THE SUBSTANCE, IN PARTICULAR FOR SOIL ANALYSIS.
