  1. Autonomously powered self-disinfectant door handle – CleanMotion (A. Horvath) – Master project in industry – P. Germano

Public facilities door handles are particularly soiled with all kind of microbes which leads to two major issues: a) a hygienic problem that make them act as a propagating vector and b) a disgusting feeling that makes the user reluctant from using public restrooms.

A start-up settled in the French-part of Switzerland is committed to solve these issues proposing a self-disinfectant handle. First by limiting the transmission of diseases and furthermore, encouraging people using public facilities by showing the active feature of the system.

After every use, a hydro-alcoholic solution is spread on the handle from a reservoir. The idea aims at developing a device being able to be installed on any standard door handle. Three major parts are to be developed: a) the actuation of the self-disinfectant system, b) the power supply that must be autonomous, and c) the irrigation system of the disinfectant pad.

  1. Electromagnetic Force Feedback & Haptics on Gaming Pedals – Logitech (J. Stoeckli) – Master project in industry (6-month TPMe) – P. Germano

E-Sports and High realism gaming engines (iRacing, etc.) are pushing the bound­aries of simulation racing. While the gaming steering wheels have improved significantly over the years, the pedals are still lacking the feel of realism provided by high-end wheels.

What if the gamer could really feel the ABS triggering in his foot, what if the gamer could feel differences in the brake pedal behavior between an old Lotus 49 and a recent Porsche 911 ?

  1. Active Force-Travel Adjustment on Keyboard/Mouse Switch – Logitech (J. Stoeckli) – Master project in industry (6-month TPMe) – P.  Germano

While keyboards and mice have been around for a very long time, they are not all created equal.

A good keyboard can increase your typing speed and decrease your error rate. In the gaming world, a good gaming keyboard can truly elevate your game, improve your skills and un-arguably enhance your gaming experience & fun. The same can be said for mice.

However, up to now, you had to settle to a particular gaming switch, if you had the chance of trying several.

This project aims at dynamically changing the Force-Travel characteristics of the switches. Ideally the behavior could be fine-tuned by the user. The main focus of this development should be around high accuracy customization of the Force-Travel curve, through the use of an active component (electromagnetic actuator, piezo, etc.)

The internship fits into a broader program on the future of gaming switches and follows an ongoing exploration on various potential implementations. This development will focus on a specific solution around electromagnetic haptic actuation.  

  1. Magnetic Levitation Demonstrator – P. Peralta

At LAI, a micro motor with (a two degrees of freedom) magnetic bearing is being developed in collaboration with a Swiss company.

The first approach towards the control of a magnetic bearing is the successful levitation of an object in a single axis. The construction of a single axis magnetic levitation demonstrator is thus proposed.

The work will demand an overview of possible levitation system topologies and their geometries. Once this is chosen, analytical and computational models are to be constructed and analyzed striving towards stiff levitation, with long airgaps and low power consumption.

The demonstrator is to be constructed, along its power its electronics. Ultimately its control to be implemented (either digitally or analogically).

  1. AI-enhanced LoRa Based Indoor Localization System – A. Boegli

GPS-based location systems suffer from accuracy deterioration and are almost unavailable in indoor environments. Building upon the ranging capabilities of newer LoRa ICs, this project aims at developing and deploy a location system able to enhance the position accuracy reached by existing LoRa-based location systems relying on TDOA or ranging mechanisms. The use of learning techniques is expected to improve accuracy. In this project, we propose to first play with such LoRa systems before starting to evaluate the use of machine learning/deep learning techniques for fingerprints based positioning.
