| 20100088754 | Authentication Method and Token Using Screen Light for Both Communication and Powering - An authentication token one side of which features an array of solar cells, of a very thin and flexible type, whereas the opposite side features a display device. The method consists in encoding into a sequence of bright images, interlaced with less bright ones, the code sent by the server. By placing the token in front of the portion of the screen displaying said encoding sequence, the light collected by the array of solar cells it is sufficient to generate the energy required for supplying the token's microprocessor, while the variation in brightness are decoded as to reconstruct the digital word representing the code sent by the server. Said code is then processed by the microprocessor to generate a One Time Password, OTP, then displayed on the display device. The user would then enter said OTP on the login page. | 04-08-2010 |
| 20100308804 | Method and Apparatus for Magnetic Contactless Measurement of Angular and Linear Positions - Contactless measurement of angular or linear positions is obtained by means of magnetic circuit configurations, biased by a permanent magnet, characterised by two airgaps whose relative geometry is designed to result in magnetic field values whose ratio is a function of the position to be measured. The magnetic field in said airgaps is measured by magnetic field probes, whose output signals are then electronically conditioned to generate a voltage proportional to said ratio. The output signal being function of a ratio, it naturally becomes insensitive to drifts of the magnet working point, or drifts in sensitivity of the magnetic field probes. In one embodiment said ratio of magnetic field values becomes a function of the relative angular displacement of two coaxial shafts, while becoming completely independent from their absolute angular displacement, allowing hence the realisation of simple and robust torque sensors. | 12-09-2010 |
