摘要:
The invention relates to an energy storage assembly, comprising a plurality of cells connected in series, wherein the series connection of cells is connected to a power output of the energy storage assembly and a control unit, wherein at least a part of the cells connected in series is connected to the power output and the control unit by way of potential-free controlled converter and control units connected in parallel, such that during the charging, discharging and recharging processes each of the cells is operated according to the individual performance characteristics of said cell by means of selective current drains by the converter and control units and a total current flowing at the power output of the energy storage assembly is formed by a base current flowing through the series connection of the cells and by additional currents, which are drained from the individual cells depending on the capacity of the cells. The invention allows for the interconnection of different cell types to form an energy storage assembly and for uniform charging or discharging thereof, thus facilitating optimal use of the energy stored and extending the total usage period.
摘要:
Disclosed are a method and a traffic routing system for controlling traffic flows in which hazardous or special material is transported through safety-critical traffic zones such as tunnels, bridges or locks. In the method and traffic routing system, safety-relevant data is read with the help of a signal transmitter disposed on the transported hazardous or special material and is transmitted to a central computer unit when said vehicle passes reading devices located in the safety-critical traffic zone. The central computer unit determines a safety risk in the safety-critical traffic zone on the basis of the safety-relevant data of all transported hazardous or special material located in the safety-critical traffic zone and sets traffic routing signals.
摘要:
An identification and/or sensor system includes a sensor that queries an identification and/or sensor configuration which contains resonators. A receiver receives an answer signal from the identification and/or sensor configuration. The receiver includes a phase-locked loop for converting a resonator decay signal into a signal of constant frequency and constant envelope curve.

A wear monitor suitable in particular for monitoring the wear and tear of rider rings (7) on the pistons (5) of horizontally operating reciprocating compressors presents a sensor (9) that monitors the thickness of the rider ring (7) at least indirectly, is arranged in the area of the rider ring (7) in such a way as to move together with it and can be interrogated without contact via a motionless interrogation unit (16), which communicates with an evaluation unit (18). The sensor (9) preferably presents a passive surface acoustic wave element (23), whose electromagnetic reflection behavior depends on the thickness of the rider ring (7) consequent upon the degree of wear and tear thereof and which communicates with a sensor antenna (19) moving together with it, while the interrogation unit (16) presents a communicating interrogation antenna (20).
