  • Publication number: 20040249693
    Abstract: A schedule table is stored in a RAM of a schedule management apparatus and in a schedule storage section of a management center. The schedule management apparatus transmits a present position detected by a GPS to the management center continuously. The management center calculates a required time period to move from the present position of the schedule management apparatus to a place included in the schedule table and, when a time calculated from an expected start time of the schedule is reached, transmits an alarm to the schedule management apparatus. This alarm is displayed on a display section of the schedule management apparatus. By starting to move to the scheduled place, a user can arrive at the place before the expected start time even when the user starts from a place quite far from the scheduled place.

  • Patent number: 6567726
    Abstract: A camera unit 10 is mounted on a vehicle 3. When an attempt is made to park the vehicle 3 in a parking lot, a predicted path 5a and guidelines 5b are displayed on an information display 4 together with an image. Data to be used for displaying the predicted path 5a and the guidelines 5b are stored beforehand in internal memory of an image processing circuit 19 provided in a parking assist ECU 6 so that the data can be selected in accordance with specifications, such as the type of the vehicle 3. The predicted path 5a is computed on the basis of a steering angle detected by a steering angle sensor provided in an exposed portion of the steering shaft 11. The length or color of the predicted path 5a is changed in accordance with the speed of the vehicle 3. Further, a vehicle driving support system is provided with a back sonar 17, and hence the length or color of the predicted path 5a is also changed in accordance with the result of detection of an obstacle.

  • Patent number: 5852804
    Abstract: A speech recognizing apparatus compares a speech command from a user with one of registration patterns stored in a storage unit in turn. Then if the speech command coincides with one of the registration patterns, the speech recognizing apparatus controls a predetermined electronic apparatus associated with an operation related to the registration pattern. If the speech command does not coincide with any one of the registration patterns, the speech recognizing apparatus stores into a memory the speech command as a new registration pattern in which the speech command is related to a manipulation of the electronic apparatus produced by the user immediately after speech command is produced.

  • Patent number: 5822439
    Abstract: A noise control device disposed at the outlet of a tail pipe which emits exhaust noise of an automobile to silence noise from the tail pipe comprises a speaker which is arranged near the tail pipe and of which the open surface has a constant angle with respect to a vertical plane, an enclosure which closes the rear portion of the speaker, and a silencing sound guide portion which guides silencing sounds emitted from the front surface of the speaker to the outlet of the tail pipe. A closed space into which a bumper for absorbing impact in case of collision is made, is used as a resonant-cavity of said speaker. Based on the amount of silencing noise which becomes greater as a plurality of microphones are arranged to be closer to the speaker, the outputs of the plurality of microphones apart a constant distance from said speaker are synthesized.

  • Patent number: 5710818
    Abstract: As in a compartment of an automotive vehicle, when a left- and a right-channel loudspeakers are disposed at angularly different positions from each other with respect to a frontward direction of a listening position, there will be formed a sound field laterally asymmetric with respect to the frontward direction of the listening position. In order to correct the asymmetry of the sound field, a crosstalk signal obtained by correcting the phase and the level of an acoustic signal of the left-channel from an acoustic signal source and a crosstalk adjustment signal obtained by correcting the level of the acoustic signal of the left-channel are fed to the right loudspeaker, or a center loudspeaker disposed between the left and right loudspeakers, together with an acoustic signal of the right-channel from the acoustic signal source.

  • Patent number: 5499302
    Abstract: In a noise controller which forms a noise cancelling sound having a phase opposite to and a sound pressure equal to those of a noise infiltrating into a closed space, any deviation in its transfer characteristics from the initial equalization is easily checked and judged owing to the provision of an adaptive filter which automatically varies the filter coefficient and forms a cancelling signal for forming a cancelling sound, a coefficient updating means which updates the filter coefficient based on an error signal after the noise has been cancelled, a simulated transfer characteristics compensation means which forms the initial equalization by simulating transfer characteristics of a transmission path via the space in which the noise is to be cancelled and forms a reproduced reference signal, a white noise generating means which generates white noise to check the initial equalization, and an initial equalization judging means which judges the accuracy of the initial equalization based on a ratio (S/N) of the

  • Patent number: 5170469
    Abstract: A data transfer apparatus transfers serial data to and from a controller. The apparatus includes a first memory which stores at least one of command data and address data of the serial data transferred from the controller, and a second memory which stores a main body portion of the serial data to be transferred to and from the controller. Changeover circuitry is provided which selectively applies the serial data transferred from the controller to either the first memory or the second memory. Further, the changeover circuitry applies a clock signal received from the controller to one of the first memory or the second memory in accordance with a latch signal received from the controller. The second memory functions to selectively store the main data portion of the serial data received from the controller and to read the main data portion of the serial data transmitted to the controller.
