  • Power-supply circuit supplied by at least two different input voltage sources
    Patent number: 6150799
    Abstract: A power-supply circuit which makes available a voltage that is obtained from at least two input-voltage sources. Connected to each input-voltage source is a current mirror which makes a current available at a control input of an output transistor joint output transistor is connected, via decoupling diodes to the input-voltage sources. Decoupling of input-voltage sources is assured by output transistors which are interconnected at output. The power-supply circuit induces a small voltage difference between the output of the power-supply circuits and the voltage of the determining input-voltage source.

  • Bus system, a peripheral device and a method for decoding a digital signal
    Patent number: 6133858
    Abstract: A method for decoding pulse-width modulated signals, such that a sawtooth signal is generated. The sawtooth signal is synchronized with a signal to be decoded. By comparing the sawtooth signal with a reference, a temporal center of a time period reserved for transmission of a bit can be measured, thus reducing a demodulation of the signal to a measurement of the signal level. Furthermore, a data bus for an activation system utilizing this method is also provided.
