Introduction

Jörg Fischer is an inventor associated with Donaueschingen, Germany, and Marquardt GmbH. His work includes an invention designed to make a vehicle’s wireless key more energy-efficient while remaining responsive to movement.

Latest Patents

Fischer is credited with 1 patent: “Wireless Key for Unlocking a Vehicle and/or for Enabling a Function of the Vehicle.” The invention describes a wireless key equipped with a motion sensor, an evaluation unit, and a transceiver that can communicate with a connection partner.

The evaluation unit switches the transceiver to a lower-energy sleep mode when the sensor detects no movement during a predetermined interval. When movement is detected, the transceiver returns to an operating mode, allowing the key to signal its availability and transmit or receive data. This approach aims to reduce energy use while preserving the key’s ability to respond when needed.
