Title: Cryptographic key generation system
Inventor: NUMAO MASAYUKI
IPC: G09C1/00
Filed: 1999-07-16
Granted: 2001-04-11
Abstract: To provide a method and a system for safely generating a cryptographic key that is separately provided to a plurality of servers. Through the collaboration of multiple users a cryptographic key is generated for the servers. Specifically, random values are exchanged among the multiple servers, and based on these values, cryptographic keys are generated. Even though the cyclic feature of the cryptographic keys of the individual servers is lost by the exchange of the random values by at least two servers, the cyclic feature for the overall system can be maintained. Public keys for the multiple cryptographic keys are generated and are published. A new public key is generated by combining a plurality of public keys, and a corresponding cryptographic key is calculated by using the cryptographic keys of the individual servers. A key updating cycle (depending on the size of a cryptographic key register) is introduced for each server, so that decryption key information appears only during a specific cycle (this is called a cyclic system). A time key is generated by the cyclic system, and when a plurality of such cyclic systems are prepared and are autonomically activated, a safer time key can be generated. In the above described distributed system that includes multiple servers, key information can not be obtained even when one system maintains its own state. Since the servers periodically update their cryptographic keys, it is ensured that the calculation of a cryptographic key will be inhibited until a decryption time has been is reached.

Title: Programmable filter for removing stuffing bits from an MPEG-2 bit-stream
Inventor: RYAN ROBERT T
IPC: H04N5/92
Filed: 1999-10-08
Granted: 2002-08-21
Abstract: An MPEG-2 video decoder which identifies and removes stuffing data from an MPEG-2 bit-stream before storing the bit-stream into the VBV buffer of the decoder. The decoder monitors the MPEG-2 bit-stream for successive groups of zero-valued bytes. When a sequence of successive of zero-valued bytes is encountered that is greater than a programmed maximum length the decoder identifies the sequence as stuffing data and inhibits any further zero-valued bytes from being passed until the next non-zero valued byte is encountered. The decoder specifies two maximum length values, one for the number of stuffing bytes which may precede a Slice start code and the other for the number of stuffing bytes which may precede a non-Slice code. These values may be changed during the decoding operation by a microprocessor.

Title: Method for casting light-alloyed wheel rim
Inventor: WENG JEN-JIE
IPC: B22D17/08
Filed: 2000-02-18
Granted: 2001-10-21
Abstract: The present invention relates to a method for casting a light-alloyed wheel rim, which includes: using a sand core with at least one positioning slot and block, a lower mold with at least one sand core positioning seat, and an upper mold with at least one wheel plate mold. The positioning slot of the sand core can contain the sand core positioning seat, and the wheel plate mold of the upper mold abuts the positioning block of the sand core for positioning the sand core, in order to avoid the movement or up-lifting of the sand core resulting from its smaller specific gravity, while the melting light alloy is poured. Meanwhile, due to achieving an accurate position it can avoid a deviation of the left and right dimensions on this light-alloyed wheel rim, or causing a problem of perforation on the light-alloyed wheel rim, and hence achieving the objective of reducing its weight. Furthermore, the sand core has a front end extending upwards in order to attenuate the thickness of the joint part between the tire ring and the spoke, and hence reduce the possibility to form shrunk holes. As a result, the yield of the light-alloyed wheel rim with good quality can be increased, and so is the product safety.
