We support the design process, from the idea to concepts to innovation. The following pictures show some examples of our projects and products.

Product: Smart Battery Charger (SMBus) In order to increase the reliability of mobile devices (e.g. measuring units), the power is supplied by "Smart Batteries". The embedded electronic components coordinate the charging process with the charging unit. The communication between battery and charger uses the SMBus (System Management Bus), similar to the I2C-Bus. We have developed a "Smart Charger" for a "Smart Battery" to power a mobile measuring device. ... more
Actuator: aviation landing flaps drive We have developed a landing flaps drive for ultralight aircraft. The operation is controlled by two position switches. We use proven components to make it easier to generate the technical documents. ... more
Product: Battery Management System (BMS) In many mobile devices we find rechargeable Lithium batteries. The offer many advantages (power density, weight), but react sensitive to unwanted stress: extrem high currents (caused by a shorted load) or overvoltages during charging. Therefore many batteries have "onboard" protective devices, creating "Smart Batteries". We have developed and tested components for BMS. ... more
Concept: software for a digital signal generator For performance tests on r/c servos we have developed a digital signal generator, so we can contribute to a better understanding of the electro-mechanical behaviour. The digital signal generator is a part of a test system (consisting of power supply and signal processing modules). ... more
Aviation: landing flaps drive control unit We have developed the landing flap drive control unit which can be easily adopted to different tasks and requirements. The shown version (according to RTCA DO-160) operates with 28 V and up to 15 A. ... more
Aviation: LAPAZ - actuator electronics for flight control system (with Stemme AG) We have developed the actuator electronics for an Automatic Flight Control System (AFCS). The flight tests are very successful: the system performed the first automatic landing on the 22. March 2012. ... more
Aviation: landing flaps drive system We have developed the landing flap drive system for a business jet aircraft (Fowler flap, spindle force 12 kN resp. 2700 lbf). ... more
Aviation: landing flaps drive system We have developed the landing flap drive system for a business turboprop aircraft (Fowler flap, spindle force 4 kN resp. 900 lbf). ... more
Aerospace: concepts for the fin actuation system of the spacecraft technology vehicle SHEFEX 2 We have designed the concepts for the fin actuation system to control the reentry of the spacecraft technology vehicle SHEFEX 2, operated by the German Aerospace Center (DLR). The mission achieved a successful flight on 22. June 2012. ... more
Consulting: thermal analysis For the safe operation of electric motors it is necessary to know the thermal limits of operation. In most cases this can only be done by experiments. ... more
Electronics: LAPAZ - actuator electronic equipment for a flight control system Stemme AG (Strausberg) developed a flight control system in the project LAPAZ. Our contribution is the actuator electronic equipment. Besides the key function of controlling the position of the motor there are numerous protective features (e.g. a two-staged brake chopper) which are well beyond the requirements outlined in RTCA DO-160. ... more
Laboratory: measurements on an injection pump actuator ("fly-by-wire") Electric actuation systems often replace manual actuation. In aircraft nomenclature this is called "fly-by-wire". This actuation system is part of a diesel engine and actuates the injection pump. ... more
Aviation: Elevator Trim Drive System We have developed the elevator trim drive system for a business jet. It mainly consists of the central drive unit with motors and gears which drives the two trim actuators. The elevator trim drive system is a "fly-by-wire" unit without mechanical connections between the cockpit and the elevator. So special reliability requirements apply. ... more
