Patent CA-2269867-A1 (CA)
Title: Rolling fishing lure with perforated panel construction
Inventor: ROSSMAN DAVID L
IPC: A01K85/16
Filed: 1999-04-22
Abstract: A fishing lure for enhanced attraction of game fish.      The lure includes a plurality of panels, each of which is provided with a plurality of perforations which establish fluid communication between the interior of the body and the surrounding water. The body of the lure has a curvature which imparts a rolling motion as the lure is drawn through the water. The rolling motion simulates the swimming motion of a bait fish, and also forces water to pass into and through the perforations in the panels.      This creates turbulence and vibrations which further simulate the characteristics of live bait fish. In a preferred embodiment, the curvature is established by joining the convex and concave edges of three crescentiform panels in edge to edge relationship around a hollow interior of the lure. The perforations may be in the form of mesh areas formed in one or more of the panels.

Title: Device and method for generating pn sequence in cdma communication system
Inventor: PARK SU WON
IPC: H04J13/10
Filed: 1999-03-23
Abstract: In a code division multiple access (CDMA) communications system, a PN sequence generating device (310) is provided to generate a PN sequence by interleaving (322, 332, 342) of cyclically shifting the symbols of an orthogonal or biorthogonal code (320, 330, 340) in accordance with a pre-defined hopping pattern (360). A receiver receives simultaneous signals from a plurality of transmitters, where each transmitted signal is spread by a PN sequence generated from the same pre-defined hopping pattern. The receiver is able to differentiate the received signals from each transmitter by varying the amount of interleaving or cyclic shift in each transmitted signal. In the PN sequence generating device (310), an orthogonal symbol generating portion (320, 330, 340) cyclically shifts mutually orthogonal and periodic orthogonal code sequences, and an orthogonal symbol selector (350) selectively outputs the cyclically shifted orthogonal symbols according to a predetermined pattern.

Title: Encryption/decryption method and authentication method using multiple-affine key system and apparatuses using the same
Inventor: SUZUKI SHUICHI
IPC: H04L9/18
Filed: 1999-12-02
Abstract: In the encryption/decryption method, a random number sequence {r i} is generated on the basis of a given key system K and encryption is performed by an exclusive OR of the random number sequence {r i} with a plain text. Further, the key system K is automatically sequentially rewritten into a series of new key systems each tame when the number "c" of use times of the key system reaches a predetermined number "n" and encryption of plain texts thereafter is continued while generating random numbers using the series of the rewritten key systems. Likewise, in decryption as well, since decryption is performed using a key system automatically rewritten each time when the number "c" of use times reaches a predetermined number "n", a third party cannot reproduce the key system and therefore cannot decipher a cipher text.

Title: A method for generating electrical conducting or semiconducting structures in two or three dimensions, a method for erasing the same structures and an electric field generator/modulator for use with the method for generating
Inventor: NORDAL PER-ERIK
IPC: H01L21/26
Filed: 1999-01-28
Abstract: In a method for generating electrical conducting or semiconducting structures in three dimensions in a matrix which comprises two or more materials in spatially separated material structures, an electric field is applied to the separate material structure or the field-modulated spatially according to a protocol which represents a predetermined pattern of electrical conducting or semiconducting structures which are generated in the material structure in response to the field. The matrix composed by the material structures will hence comprise structures of this kind in three dimensions. In a method for global erasing an electric field is applied to the matrix until the materials in the matrix in response to the field in their entirety arrive in a non-conducting state. In an electric field generator/modulator (EFGM) which can be used for patterning and generating electrical conducting or semiconducting structures, two electrode means (E1;E2) comprise parallel strip electrodes (21;22) provided mutually spaced apart in parallel planes such that the electrodes (21, 22) form a matrix-like arrangement. The electrode means (E1;E2) are over cross-connection devices (24, 25) connected with a power supply (23). EFGM (20) is adapted for receiving a thin-film material between the electrode devices (E1, E2) in order to generate said structures.
