Abstract: A method and associated apparatus for operating a power station of fluctuating electrical capacity that, besides a voltage-setting system former outputting active power and reactive power and at least one load, is connected to a limited AC grid. The method and associated apparatus includes defining a desired self-contained operating range of the system former on the PQ level, in which operating range the system former is able to efficiently correct fluctuations arising in a mains voltage of the AC grid, ascertaining a present operating point of the system former on the PQ level, and controlling an output of active power and reactive power by the power station such that the operating point of the system former is kept in the desired operating range.

Abstract: In a method for black start of a power station including a plurality of inventers connectable to a local AC electrical grid, a first AC voltage is built up in the AC electrical grid by a first inverter, said first AC voltage being reduced in comparison with a rated voltage of the AC electrical grid by at least a quarter, and at least one second inverter is connected to the AC electrical grid after synchronization with the first AC voltage. After connection of the second converter, a second AC voltage, which is higher than the first AC voltage, is built up in the AC electrical grid.

Abstract: The present invention relates to a contacting unit (t) for electrical conductors or pin contacts (8). Contacting units (1) of this kind are used for reversibly contacting said conductors or pin contacts (8) in an electrical and mechanical manner. In the present invention, the spring force that acts on a conductor or pin contact (8) to be connected can be variably adjusted. To this end, the free, spring-loaded length of a spring contact member (11) is varied by means of a sliding element (20). As a result of the variation of the spring-loaded length of the spring contact member (11), the spring force is increased in the case of a shortening and is correspondingly reduced in the case of an extension.

Abstract: This disclosure describes compositions and methods for selectively recruiting antigen-specific T cells and re-direct them to kill targeted cells, particularly tumor cells. This approach permits selective engagement of specific effector cell populations and, by using nanoparticles, overcomes the geometric limitations associated with previous approaches.

Abstract: The present invention relates to a single- or multi-layered synthetic film primarily consisting of biodegradable polymers, said synthetic film consisting of one or more layers (a) of at least one biodegradable polymer and 1-35% by weight, relative to the total weight of the layer (a), of at least one modified, thermoplastic copolymer of ?,?-unsaturated olefins having 2-10 carbon atoms and (meth)acrylic acid and/or at least one (meth)acrylic acid derivative that is grafted, preferably with cyclic anhydride groups and/or carboxyl groups and/or ester groups, said invention further relating to a use of such a synthetic film as packaging material.

Abstract: An insulating body is captively secured on the housing for a plug connection having insulation displacement terminals. The insulating body is held on guide of the housing in a rotatable manner and in an insertable manner into the housing via an opening. The guide can be formed as slits that lie in lateral parts of the housing. The lateral parts project beyond the housing. Electric conductors can be inserted into the insulating body on a rear surface, plugged through said body, and cut on a front surface. The electric conductors are thus brought to the intended length before the insulating body is inserted into the housing.

Abstract: In order to simplify the assembly of printed board connectors, there is provided an assembly aid that features one or more recesses in accordance with the dimensions of the printed board connectors, wherein one or more printed board connectors to be assembled on a printed board can be inserted into said recesses. The contact spacing on the printed board corresponds with the arrangement of the printed board connectors in the assembly aid such that an exact alignment of the printed board connectors is realized. The assembly aid remains on the printed board until the soldering process is completed, wherein this prevents, for example, flotation of SMD components.

Abstract: An insulating body (3) is captively secured on the housing (1) for a plug connector (1) comprising insulation displacement terminals (23). The insulating body (3) is held on guiding means of the housing in a rotatable manner and in an insertable manner into the housing via an opening. The guiding means can be formed as slits (22, 22?) that lie in lateral parts (21, 21?) of the housing. The lateral parts project beyond the housing. Electric conductors can be inserted into the insulating body on a rear surface, plugged through said body, and cut on a front surface. The electric conductors are thus brought to the intended length before the insulating body is inserted into the housing.

Abstract: In order to simplify the assembly of a shielded connector, it is proposed that an electrically insulating base body provided as a carrier for electric contacts features a mounting surface with two openings, wherein a recess that respectively features an integral collar on its inner side is respectively arranged around these openings. In addition, the base body is provided with lateral fastening elements that respectively feature a window formed by a frame. The frame can be positively fitted into the appropriate recess by bending the fastening elements such that the fastening element is positively and non-positively fixed on the base body. An electrically conductive shielding element that largely surrounds the base body contacts the fastening elements that, in turn, contact ground strips on the circuit board such that the connector is shielded from external voltages.

The acceleration detector determines an inclination parameter, wherein the movement of the software cursor in a vertical direction is controllable based on the inclination parameter. Further, the image capturing unit records images within the visible spectral range, wherein the movement of the software cursor in a horizontal direction is controllable based on the recorded images.
