Title: Data transfer system wherein error propagation is decreased
Inventor: RUSSELL MARK ALAN
IPC: H04B3/04
Filed: 1992-12-08
Abstract: PURPOSE: To provide a data transmission system in which the increase of a symbol error ratio as the result of deviation for the nominal value of the transfer function of a channel is reduced. CONSTITUTION: Data to be transmitted are encoded by an encoder 2 having a transfer function almost opposite to the transfer function of a channel 4 for avoiding error proliferation as the result of judgment feedbacking or the like. As a result, judgment related with a received symbol is executed by a receiver 6 so that interference between the symbols can not result in disturbance. When the transfer function of the channel is different from the transfer function of a pre-encoder 2, the interference between the symbols is generated again, and the symbol error ratio is increased. The receiver is provided with a serial connecting circuit between an adaptive filter 18 having the transfer function opposite to that of the channel, and a decoder 21 having the transfer function opposite to that of the pre-encoder 2 for limiting the increase of this symbol error ratio as much as possible.

Title: Probe card identification system for computer supported production
Inventor: DE VILLENEUVE THIERRY
IPC: G01S13/78
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To automatically identify a probe card by containing a prober which receives probe card, and also containing a probe card holding a transponder tag, a magnetic coupling antenna and a circuit which is connected to this antenna. SOLUTION: The probe card 170 has a round hole 172 at its center part that is concentric with the hole of a spring contact ring when the card 170 is used. A probe pin 180 is soldered on the upper surface of the card 170 and around the hole 172. A carrier 220 is identical with a small part of the card that is held by a pin 222 which is attached to the card 170 at one of its both ends and also to the carrier 220 at the other end respectively. These carrier 220 and pin 222 function to prevent a transponder tag from moving to a prove card to another. Thus the transponder tag protrudes through the contact ring hole when the card 170 is attached into a prober owing to use of the carrier 220.
