For the integration mainly digital interfaces are used, starting from rather simple pulse-width modulation (PWM) interface to more complex interfaces like CAN (Controller Area Network). Even though these interfaces are tethered by definition, a wireless realization is highly welcome in many applications to reduce cable and connector cost, increase the flexibility and realize new emerging applications like wireless control systems. Currently used wireless solutions like Bluetooth, WirelessHART or IO-Link Wireless use dedicated communication standards and corresponding higher protocol layers to realize the wireless communication. Due to the complexity of the communication and the protocol handling, additional latency and jitter are introduced to the data communication that can meet the requirements for many applications. Even though tunnelling of other bus data like CAN data is generally also possible the latency and jitter prevent the tunnelling from being transparent for the bus system. Therefore a new basic technology based on dual-mode radio is used to realize a wireless communication on the physical layer only, enabling a reliable and real-time data transfer. As this system operates on the physical layer it is independent of any higher layers of the OSI (open systems interconnection) model. Hence it can be used for several different communication systems to replace the tethered physical layer. A prototype is developed and tested for real-time wireless PWM, SENT (single-edge nibble transmission) and CAN data transfer with very low latency and jitter.}, language = {en} } @article{KowalewskiBragardHueningetal.2023, author = {Kowalewski, Paul and Bragard, Michael and H{\"u}ning, Felix and De Doncker, Rik W.}, title = {An inexpensive Wiegand-sensor-based rotary encoder without rotating magnets for use in electrical drives}, series = {IEEE Transactions on Instrumentation and Measurement}, journal = {IEEE Transactions on Instrumentation and Measurement}, publisher = {IEEE}, issn = {0018-9456 (Print)}, doi = {10.1109/TIM.2023.3326166}, pages = {10 Seiten}, year = {2023}, abstract = {This paper introduces an inexpensive Wiegand-sensor-based rotary encoder that avoids rotating magnets and is suitable for electrical-drive applications. So far, Wiegand-sensor-based encoders usually include a magnetic pole wheel with rotating permanent magnets. These encoders combine the disadvantages of an increased magnet demand and a limited maximal speed due to the centripetal force acting on the rotating magnets. The proposed approach reduces the total demand of permanent magnets drastically. Moreover, the rotating part is manufacturable from a single piece of steel, which makes it very robust and cheap. This work presents the theoretical operating principle of the proposed approach and validates its benefits on a hardware prototype. The presented proof-of-concept prototype achieves a mechanical resolution of 4.5 ° by using only 4 permanent magnets, 2Wiegand sensors and a rotating steel gear wheel with 20 teeth.}, language = {en} } @article{HueningEifertHandricketal.2006, author = {H{\"u}ning, Felix and Eifert, T. and Handrick, K. and Neuhausen, U.}, title = {Computational Magnetochemistry: Complementary Quantum Mechanical Tools / Eifert, T. ; Handrick, K. ; H{\"u}ning, F. ; Neuhausen, U. ; Schilder, H. ; Lueken, H.}, series = {Zeitschrift f{\"u}r Anorganische und Allgemeine Chemie (ZAAC) - Journal of Inorganic and General Chemistry . 632 (2006), H. 4}, journal = {Zeitschrift f{\"u}r Anorganische und Allgemeine Chemie (ZAAC) - Journal of Inorganic and General Chemistry . 632 (2006), H. 4}, publisher = {-}, isbn = {1521-3749}, pages = {521 -- 529}, year = {2006}, language = {en} } @article{HueningEifertHandricketal.2006, author = {H{\"u}ning, Felix and Eifert, T. and Handrick, K. and Neuhausen, U.}, title = {Computational Magnetochemistry: Complementary Quantum Mechanical Tools / Eifert, T. ; Handrick, K. ; H{\"u}ning, F. ; Neuhausen, U. ; Schilder, H. ; Lueken, H.}, series = {20 Jahre Wilhelm-Klemm-Stiftung / Kuratorium der Wilhelm-Klemm-Stiftung (Hrsg.)}, journal = {20 Jahre Wilhelm-Klemm-Stiftung / Kuratorium der Wilhelm-Klemm-Stiftung (Hrsg.)}, publisher = {Shaker}, address = {Aachen}, isbn = {978-3-8322-5520-6}, pages = {193ff}, year = {2006}, language = {en} } @article{Huening2008, author = {H{\"u}ning, Felix}, title = {Die Anforderungen steigen : Entwicklungstrends bei MOSFETs f{\"u}r den Automobilbereich}, series = {Elektronik-Industrie. 39 (2008), H. 5}, journal = {Elektronik-Industrie. 39 (2008), H. 5}, publisher = {-}, isbn = {0174-5522}, pages = {74 -- 76}, year = {2008}, language = {de} } @article{HueningBackes2020, author = {H{\"u}ning, Felix and Backes, Andreas}, title = {Direct observation of large Barkhausen jump in thin Vicalloy wires}, series = {IEEE Magnetics Letters}, volume = {11}, journal = {IEEE Magnetics Letters}, number = {Art. 2506504}, publisher = {IEEE}, address = {New York, NY}, isbn = {1949-307X}, doi = {10.1109/LMAG.2020.3046411}, pages = {1 -- 4}, year = {2020}, language = {en} } @article{HueningWilkeNakielskietal.1997, author = {H{\"u}ning, Felix and Wilke, I. and Nakielski, G. and Kotzler, J.}, title = {Dynamic conductivity of YBCO thin films from low to very high frequencies / Wilke, I. ; Nakielski, G. ; Kotzler, J. ; Subke, K.

The Wiegand effect, in contrast to continuous sources like photovoltaic or thermal harvesters, provides small amounts of energy discontinuously in pulsed mode. To enable an energy-self-sufficient operation of the sensing device with this pulsed energy source, the output energy of the Wiegand generator is maximized. This energy is used to power up the system and to acquire and process data like position, temperature or other resistively measurable quantities as well as transmit these data via an ultra-low-power ultra-wideband (UWB) data transmitter. A proof-of-concept system was built to prove the feasibility of the approach. The energy consumption of the system during start-up was analysed, traced back in detail to the individual components, compared to the generated energy and processed to identify further optimization options.
