Patent DE-19800805-A1 (DE)
Title: Reference signal generation for magneto-resistive sensor
IPC: G01D5/14
Filed: 1998-01-12
Abstract: The method involves using a magneto-resistive sensor (1) in a full-bridge arrangement and a translational or rotational magnetic scale (2), whereby a single magnetic pole is incensed at a reference position (R) of the scale. The full-bridge arrangement is formed through combination of two identical half-bridge arrangements (H1, H2), in which respectively two identical bridge resistances (R11, R12 and R21, R22) are arranged around the base width (4) of the sensor. The resistances are arranged with a defined geometric phase shift in scale direction, so that a difference of the two point-symmetric output signals of the half-bridge arrangements result in an axis-symmetric output signal of the full-bridge arrangement.

IPC: H01L21/225
Filed: 1998-03-25
Abstract: The invention relates to a method for doping one side of semiconductor bodies, especially of silicon wafers.

Patent DE-19820422-A1 (DE)
Inventor: VEDDER KLAUS
IPC: G07F7/10
Filed: 1998-05-07
Abstract: The invention relates to a method for authenticating a chip card (SIM) in a network for transmitting messages, preferably in a GSM network. According to said method, an optionally secret algorithm and a secret key are stored in a chip card (SIM). In order to authenticate the card, the network or a network component first transmits a random number to the chip card. A reply signal is then generated in said chip card using the algorithm, the random number and the secret key, and transmitted to the network or network component where the authenticity of the card is checked. The authentication message is formed by dividing the secret key and the random number transmitted by the network into at least two parts each. A part of the transmitted random number and one or more parts of the secret key are encoded with a single or multi-stage, preferably symmetrical computation algorithm. A selected part of the product of the encoding procedure is transmitted to the network in order to issue an authentication reply.
