| 20110285334 | METHOD FOR OPERATING A BRUSHLESS MOTOR - The present invention relates to a method for operating a brushless electric motor whose windings are driven by an inverter with the aid of six switches, having an identification unit being provided in order to identify defective switches, a unit for voltage measurement at the outputs of the inverter, and a microcontroller for controlling the switches. Particularly in safety-relevant applications, it is important to quickly determine what characteristic the defective switch has, for example in order to continue to operate the electric motor in an emergency mode, or to switch it off immediately. The defect (F | 11-24-2011 |

| 20100279947 | Modifications of apoptin - Phosphorylated Apoptin is described. Apoptin is tumor-specifically phosphorylated and part of the Apoptin apoptotic pathway in tumor cells is elucidated. New therapeutic possibilities, for example, novel therapeutic compounds that can work alone or, sequentially to, or jointly with other known compounds. Also, the use of tumor-specifically phosphorylation of Apoptin for diagnostic purposes is described. Such a diagnostic purpose can, for example, be a method for detecting the presence of cancer cells or cells that are cancer prone or a method to identify a putative cancer inducing agent or a method for the in vitro treatment effect of Apoptin on tumor cells by testing the phosphorylation state of Apoptin. Even more, the invention provides possibilities to further elucidate the apoptotic pathway and to identify for example crucial mediators of phosphorylation in human tumor cells. Interfering with such a mediator could provide new anti-cancer therapies. | 11-04-2010 |

| 20090021083 | POWER GRID FILTER CHOKE - The object of the invention is to implement a circuit arrangement, which in rated operation without resonance generates as little power loss as possible, but on suitable excitation effects a disproportionate asymmetrical damping, so that resonances and overvoltages associated with them are avoided. The object is attained by using a damping member 5a, b, c, which effects the damping in proportion to a primary circuit parameter. The advantage is the adaptive performance of a power grid filter equipped with the choke of the invention. | 01-22-2009 |
