Arrangement and method for contactless energy transmission with a coupling-minimized matrix of planar transmission coils

Abstract: The invention relates to an arrangement and a method for contactless energy transmission by means of induction. There is a plurality of coils arranged in a matrix, wherein the coils have at least one conductor, which, at least once, surrounds a central axis of the associated coil in one turn. The central axis is perpendicular to the area surrounded by the conductor at the geometric centre of the surrounded area. The coils are arranged next to one another in a planar unit which extends in a first dimension, a second dimension and a third dimension. The extent of the planar unit in the first dimension and in the second dimension is substantially greater than in the third dimension. The central axis of each coil is, at least locally, at least virtually perpendicular to the area spanned by the first dimension and the second dimension. In addition, the coils are arranged within the planar unit regularly in rows and/or columns in such a way that each coil has at least two or three directly adjacent coils. The distances between the geometric centres of area of the coils with respect to one another and the shape and the spread of the at least one turn per coil are selected such that the mutual electromagnetic coupling between the associated coils is minimal for all pairs of directly adjacent coils in the planar unit.

An FPGA based approach for the enhancement of COTS switch ASICs with real-time Ethernet functions

Abstract: This paper presents an approach for the enhancement of standard switch ASICs with real-time Ethernet functions. Whereas a standard switch ASIC provides sophisticated mechanisms for switching of non real-time frames, an attached FPGA implements cut-through switching of real-time frames. The proposed FPGA architecture supports configuration of port numbers, bandwidth reservation for real-time frames and utilizes flow-control mechanisms of the ASIC in order to keep frame buffer sizes low. Mapping exemplary RTE extensions of PROFINET IRT onto a Xilinx Spartan 6 FPGA demonstrates the capability of providing band-width reservation and cut-through-forwarding of real-time frames. Therefore, the approach benefits from the innovations made by the switch manufacturers, whereas only a small amount of functions has to be mapped onto an FPGA.
