20130086389 | Security Token and Authentication System - Techniques are provided for entering a secret into a security token using an embedded tactile sensing user interface with the purpose of verifying the secret against a stored representation of the same secret. In particular, an embodiment of the security token according to the invention comprises a tactile sensing user interface being arranged to receive a user-encoded secret, a decoding unit being arranged to generate a decoded secret by decoding the user-encoded secret, a comparison unit being arranged to compare the decoded secret with a copy of the secret stored in the token in order to verify the authenticity of a user. Thereby, the security token provides on-card matching functionality. | 04-04-2013 |
20130114124 | PASSIVE MULTIPLEXING EXTENSION FOR ELECTRONIC PAPER DISPLAYS - A single-segment drive scheme for an electronic paper display (EPD) is replaced by a multiplexed drive scheme that reduces the number of driver pins to the number of display segments per digit or alphanumeric character plus one input/output (I/O) line per digit or alphanumeric character. In accordance with the invention, a passive digit selection mechanism enables a multiplex display drive scheme when the EPD material used typically has a stable threshold combined with a small hysteresis. Typically, display operation is better the smaller the hysteresis and the more stable the threshold of the EPD material that is used. | 05-09-2013 |
20140091815 | CAPACITIVE POSITION SENSOR SYSTEM - A capacitive position sensor system for determining the position of an object, in particular on a surface of a contactless smartcard, is provided.
