20120305646 | Artificial Fingerprint - An identification label with a three-dimensional wrinkled structure may be formed by depositing a hard film with a high elastic modulus on an elongated substrate of a lower elastic modulus. Wrinkles with defects develop as the substrate is subsequently allowed to relax. Defects such as ridge endings and ridge bifurcations are randomly distributed over the wrinkled surface, and allow to uniquely identify any given identification label with the high degree of accuracy. Since the formation of defects is a random process, the wrinkled structure cannot be reproduced or counterfeited. The labels are thus forgery-proof. | 12-06-2012 |

20090021174 | Controlling a Lamp Ballast - A method and apparatus for providing electrical current to a lamp, detecting a power supply voltage outage, detecting a return of the power supply voltage, determining how long the power supply voltage outage lasted, and preheating the lamp responsive to determining that the power supply voltage outage lasted greater than a threshold amount of time. | 01-22-2009 |
20090256487 | Method for detection of non-zero-voltage switching operation of a ballast of fluorescent lamps, and ballast - A method detects a non-zero-voltage switching operation of a lamp ballast, the lamp ballast including a half-bridge circuit with a first and a second semiconductor switching element, a resonant circuit connected to the half-bridge circuit, and a snubber capacitance connected in parallel with one of the semiconductor switching elements. The method includes obtaining a voltage measurement signal representative of a voltage at an output of the half-bridge circuit. The method also includes providing a comparison signal representative of a comparison of the voltage measurement signal with a reference value. The method further includes evaluating the comparison signal in each case before the first semiconductor element is switched on and in each case before the second semiconductor element is switched on, and detecting one of a first and second non-zero-switching operations based on these evaluations. | 10-15-2009 |
20120062137 | Method for Detection of Non-Zero-Voltage Switching Operation of a Ballast of Fluorescent Lamps, and Ballast - A method for use in a lamp ballast includes obtaining a measurement signal representative of a voltage at an output of a half-bridge circuit. The half-bridge circuit includes first and second semiconductor switching elements, a resonant circuit connected to the half-bridge circuit, and a snubber capacitance connected in parallel with one of the semiconductor switching elements. The method also includes providing a comparison sinal by comparing heeasurem ment signal with a reference value. The method further includes detecting one of a first type of non-zero-voltage switching operation and a second type of non-zero-voltage switching operation based on evaluations of the comparison signal, wherein the evaluations of the comparison signal occurs in each case before the first semiconductor element is switched on and in each case before the second semiconductor element is switched on. | 03-15-2012 |
