A power generation system (10) for generating electrical power, which may vary in response to one or more weather-varying factors (11). The system may include an array of power generators (12) subject to the weather-varying factor. A module (18) may be configured to predict over a time horizon at least one power-generating condition for the array of power generators. A controller (24) may be configured to anticipatorily adjust a control strategy regarding operation of a component and/or subsystem of the power generation system based on the predicted power-generating condition for the array of power generators over the time horizon.

An improved Braille erasure mechanism may comprise a reverse-embosser or impressing mechanism to imprint a negative Braille cell. A negative Braille cell is the reverse of a normal Braille cell, with one or more dots lowered or pressed into the printing medium in an opposite direction to the raised dots of a normal Braille cell. Because the dots of a negative Braille cell are lowered past the surface of the printing medium, they may be ordinarily undetectable to the fingers of a Braille user. Accordingly, by imprinting a full negative Braille cell on top of a Braille cell to be erased, all of the previously raised dots of the Braille cell may be lowered beyond the surface of the printing medium. Any further Braille cell embossed over the erased cell will be free from corruption, because any dot not used by the new cell will remain lowered and undetectable.

In a clip for fastening to a strip or rib, in particular on a motor vehicle, having a single-piece body made of plastic that has a retaining region, the retaining region has a receiving slot with an insertion opening and a locking finger. The locking finger is attached to a first guide section and extends from its fastening end in the insertion direction and in the direction of a second guide section. The locking finger has an insert that forms a tongue projecting from the free end of the locking finger.

A joining component, for axial joining to a workpiece, comprises a base body composed of thermoplastic material and including a holding section and a flange section, with a joining surface including both a portion of the flange section and a metal section which can be heated inductively. The metal section is in this case integrated in the flange section.

A device for exhaust gas recirculation for a combustion engine is provided that includes an exhaust gas pipe configured to conduct exhaust gas and a channel configured to conduct air to the combustion engine. The exhaust gas pipe terminates in the channel, wherein the exhaust gas pipe, in an area of insertion in the channel exhaust, is in thermal exchange with a coolant from a coolant circuit.

The invention relates to a method for axial joining of a hybrid joining component to a workpiece, wherein the joining component has a thermoplastic joining section and a metal section which can be heated, having the following steps: moving the joining component into contact with a surface of the workpiece; heating of the metal section such that the joining section at least partially melts; ending the heating of the metal section such that the joining component makes a force-fitting, interlocking and/or integral connection with the surface of the workpiece. In this case, the joining component is held with a regulated force and/or in a regulated position with respect to the workpiece at least during the heating of the metal section, in such a manner that the joining component can be joined to the surface of the workpiece without any opposing support.

A method and device is provided for the detection of data symbols contained in a received radio signal, whereby each data symbol is allocated transmit-side a symbol value-specific PN sequence of successive PN chips in the chip clock and the PN sequences allocated to the data symbols are offset QPSK modulated. The method of the invention for incoherent detection provides for converting the received radio signal into a complex baseband signal sampled in the chip clock, generating a demodulated signal by differential demodulation of the complex baseband signal sampled in the chip clock, providing the derived sequences, calculating correlation results by correlating the demodulated signal with the derived sequences, and deriving, i.e., detecting, the values of the data symbols by evaluating the correlation results. In this case, each derived sequence is assigned to a PN sequence allocable transmit-side and includes derived chips, whose values in each case correspond to a logic linking of particular PN chips of the PN sequence allocable transmit-side that is assigned the derived sequence. The invention relates furthermore to a corresponding receiving unit.

The invention relates to an electronic component having a semiconductor component, particularly a semiconductor chip, and at least one SMD component, a chip carrier with a support platform and with connecting leads. Whereby the semiconductor component, which is connected electrically via chip bonds to bond fingers of the connecting leads is mounted on the support platform and the SMD component connects the support platform to a connecting lead via contact surfaces arranged thereon, a housing, which encloses the semiconductor component, the SMD component, and at least partially the chip carrier. The support platform and the connecting lead in the area of the SMD component are profiled to create barriers in such a way that flowing of a free-flowing material from the contact surfaces connected to the SMD component of the chip carrier both onto the support platform and onto the connecting lead is prevented.
