    摘要: A method and system for generating a secret key from joint randomness shared by wireless transmit/receive units (WTRUs) are disclosed. A first WTRU and a second WTRU perform channel estimation to generate a sampled channel impulse response (CIR) on a channel between the first WTRU and the second WTRU. The first WTRU generates a set of bits from the sampled CIR and generates a secret key and a syndrome, (or parity bits), from the set of bits. The first WTRU sends the syndrome, (or parity bits), to the second WTRU. The second WTRU reconstructs the set of bits from the syndrome, (or parity bits), and its own sampled CIR, and generates the secret key from the reconstructed set of bits.

    摘要: A compressible electrical contact is disclosed. The compressible electrical contact may include a nose portion, a corrugated portion and a tail portion. The tail portion may extend from a first end of the corrugated portion and the nose portion may extend from an opposite end of the corrugated portion. The corrugated portion may define a first surface and a second surface opposite the first surface. The first and second surfaces may have a width. The corrugated portion may also have a third surface extending between the first and second surfaces and a fourth surface opposite the third surface. A plurality of corrugations may be formed in the third and fourth surfaces of the corrugated portion wherein a first corrugation may extend at least partially between an upper portion and a lower portion of the nose portion.
