  • Publication number: 20020054331
    Abstract: A method and system to send a card with a photograph able to remotely create a post-card, with a photo taken by a sender, and send the postcard to any destination regardless of who is to receive it. In particular, this invention discloses a method by which a customer can use a photo terminal having a communication capacity connected via a computer network to the computer system at a print shop to request that the print shop remotely creates and sends a card with a photo on it. The image to be printed on the card and the text data, including the name and address of the recipient and the name of the sender, are transmitted from the photo terminal to the computer network, and the customer requests that the print shop remotely creates and sends the card. The computer system at the print shop receives the image and text sent via the computer network, and the order to print remotely and send the postcard.

  • Patent number: 5987420
    Abstract: The present system comprises a device which issues tickets, a central processing device and an entrance gate device which controls entry to the site. The central processing device establishes appropriate data representing the maximum carrying capacity of each attraction (i.e., the maximum number of reservations which can be given out). It does so by performing a fuzzy inference based on fuzzy rules using as fuzzy variables various uncertainty factors which influence cancellations and other events that transpire after a reservation is made, such as type of attraction, weather, time of day, day of the week and season.

  • Patent number: 5760886
    Abstract: A scanning-type distance measurement device is responsive to selected signals to reduce interference due to stray light. An emitted beam of light is aimed to be reflected from an object and to a photodetector among a plurality of photodetectors which are positioned linearly or in two-dimensions. The outputs of the photodetectors are selected based on the position of the emitted beam of light, so that photodetectors which should not contribute to the reflected beam, based on the geometry of the emitted beam and the reflecting object, are ignored. This approach reduces the effects of stray noise from other light sources. The selection of the photodetectors is synchronized with a scanning light emitter generating the beam of light by a position signal and an angular signal so that the noise component in the output signal which is due to stray light can be kept to a minimum.

  • Patent number: 5655056
    Abstract: A group control system in which a plurality of fuzzy controllers are interconnected by a communication line and the parameters of rules and membership functions of each fuzzy controller are capable of being adaptatively changed depending upon the state of the controlled system so as to improve the control performance of the overall system.

  • Patent number: 5515156
    Abstract: A safety distance measuring device employing an electromagnetic wave is provided. A laser diode 2 is energized to emit laser beams by a laser diode drive circuit 3 in accordance with a clock signal generated by a control circuit 29. The emitted laser beams are sequentially changed to predetermined scanning directions by a scanner 1 associated with control circuit 29. The scanned laser beams from scanner 1 are reflected by an object 19 to be received by a photodiode 5. An output of the photodiode is applied to control circuit 29 through a light receiving circuit 6 where an elapsed time from emission to receipt is computed to obtain a distance from scanner 1 to object 19. Based on data relating to scanning directions by a scanning position detector 4, a begin-and-end detecting circuit 28 can stop the radiation of electromagnetic waves around a scanning start point and a scanning end point which is danger to human bodies.

  • Patent number: 5367610
    Abstract: In a fuzzy controller comprising a fuzzy inference device for subjecting one or a plurality of input signals to fuzzy inference operations using membership functions in accordance with a predetermined rule and outputting a non-fuzzy value determined on the basis of the results of the inferences, there are provided an input signal level converter for converting signal levels of the input signals on the input side of the fuzzy inference device and an output signal level converter for converting a signal level of the output signal on the output side of the fuzzy inference device.
