Title: Optical waveguide covered power cable
Inventor: UCHINO MICHIO
IPC: G02B6/44
Filed: 1994-01-10
Abstract: PURPOSE:To enhance the accuracy of sensing any damage of a power cable by forming an optical waveguide on the outside of an insulated conductor of a power cable through lamination of a plurality of materials having different refractive indices. CONSTITUTION:An optical waveguide path 4 is formed on an insulated conductor 1 prepared by applying an insulating material 3 onto a conductor 2, and outside of the path 4 a plastic sheath 8 is put to form a power cable equipped with a covering film as optical waveguide path. The waveguide path 4 is made by laminating a covering layer 5 of a material having a refractive index n1, covering layer 6 of another material having refractive index n2, and covering layer 7 of the material having the refractive index n1, one over another. The layers 5, 7 of the same index n1 serve as a clad layer while the layer 6 serves as a core layer. Because this causes increase of the optical transmission loss even for a damage of cable in any place, damage sensing can be made accurately. If a boring process is applied to the plastic sheath 8 so that part of the light leaks from the waveguide 4, it can be used to make evacuation of people in case of emergency in a cave road or the like.

Title: Variable key press resynchronization method for remote keyless input system
Inventor: KELL CURTIS NORMAN
IPC: E05B65/20
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To facilitate resynchronization by practicing a resynchronization procedure to restore synchronism between a transmitter and a receiver by the receiver which receives a message from the transmitter. SOLUTION: A remote keyless system 10 is composed of a transmitter 12 and a receiver 18. A resynchronization process is established in an environment where a message structure is not certified and the receiver 18 fails to practice a function code since a signal 16 does not coincide with a stored value when an FR signal 16 radiated from the transmitter 12 is received by the receiver 18 after a button 14 is pushed. In this environment, the receiver 18 establishes one of a set of resynchronization processes capable of demanding to push the button 14 by the additional number of times so as to be understood as completely intuitive reaction to clear initial failure of the function code to be practiced. Therefore, a special resynchronization means can be obviated, and since an EEPROM can be eliminated, a cost of the transmitter can be reduced, and FR design of the receiver can be reduced.

Title: Signal multiplex system converter
Inventor: ONISHI MAKOTO
IPC: H04N7/08
Filed: 1992-01-29
Abstract: PURPOSE:To enable the system conversion of an optional multiplexing number to expand a designation freedom degree by converting the system of a multiple signal through the use a pass band variable filter consisting of a sampling frequency converter with a time change coefficient filter. CONSTITUTION:A sign inverter 89 removes the frequency inversion of the channel of an odd number-th and the signal is inputted into an M-channel multiple filter consisting of delay elements 811 to 81N, coefficient multipliers 20 to 2N and adders 41 to 4N. The filter is multiplexed the elements 811 to 81N so that the signal of the channel is outputted by each time slot. A filter coefficient written in ROMa 86 is read out a phase shift coefficient which is different at the each time slot from ROMb 5 and is multiplied by coefficient multipliers 30 to 3N. Consequently, a signal shifted into a desired band can be obtained and if, furthermore, converting it with the sampling frequency converter 80, a desired FDM signal can be obtained. Thus, an optional multiplex number can be system-converted so that the designation freedom degree can be expanded.
