Title: Fiber optic gyro with reduced zero-point output drift
Inventor: OHNO ARITAKA
IPC: G01C19/72
Filed: 1991-09-19
Abstract: Light from a light source is linearly polarized by a polarizer and is then splitted by an optical splitter/couler into two, which are simultanesouly coupled, as right-handed light and left-handed light, into both ends of an optical fiber coil.  The right-handed light and left-handed light emitted from the both ends of the optical fiber coil are coupled by the optical splitter/couler into interference light, which is extracted after passing through the polarizer and is converted into an electric signal corresponding to its intensity.  The phase difference between the right-handed light and the left-handed light, corresponding to an angular rate applied to the optical fiber coil, is detected from the electric signal.  In the present invention, a depolarizer is inserted in series at an arbitrary position in a loop from one end of the optical splitter/couler to the other end thereof via the optical fiber coil.  The difference between the difference in propagation time between perpendicularly intersecting polarized light components in the depolarizer and the difference in propagation time between perpendicularly intersecting polarized light components in the optical fiber coil is selected larger that the coherence time of light which passes through the loop.

Title: Autovehicle check system
Inventor: TAK SEUNG H
IPC: G07B15/00
Filed: 1990-12-29
Abstract: The parity bar codes are arranged side by side adjacent to data bar code. Reference bar codes having a predetermined length and width are positioned adjacent to the data bar code and parity bar code, respectively, a bar code identification scanner compares actual identification data code and parity bar codes with the reference bar codes with a bar code identification angle being changed during the running of an autovehicle and corrects the data code and parity bar codes adjacent to each of reference bar codes by the angle difference between the actual code and the identified code as well as reads them. The corrected data are stored as the identification data at an inner RAM of the scanner. The parity data are decoded to make the scanner judge whether the identification data are error. Next, if the identification data are error, the identification data is canceled. If not, the other parity code is checked, once more. If not, only the identification data are transmitted as the actual data to a regional computer or a central computer. Thus, the autovehicle check system can exactly determine at least one bar codes adhered to a predetermined place of autovehicles, so that it may effectively manage a highway or a trunk road relative to autovehicles.

Patent CA-2075811-A1 (CA)
Inventor: MANICO JOSEPH A
IPC: H04N1/50
Filed: 1991-12-17
Abstract: A hybrid multiple color print reproduction scheme for a digital color image photo-finishing system employing a digitally driven high spatial resolution color printer converts a stored digital positive (e.g. RGB-representative) color image into a second digital color (e.g. CYM-representative) image. This second digital image effectively corresponds to a mirrorreversed complement of the positive color image and is digitally adjusted such that its tone and color characteristics optimize reproduction of the posi-tive image via a conventional chemical development process. The complement color image is output to a digital printer (20) which prints an "internegative" image onto a transparency medium (22), rather than the customary print paper. This digitally produced "internegative" (22) is used to replicate multiple copies of the original image (16) using a conventional analog electro-optic sys-tem (21, 28) and an associated chemical-based print developing unit (30), thereby providing a substantial savings in reproduction time and costs.
