  • Patent number: 8734578
    Abstract: An indoor dust collecting system includes an air conditioner having an indoor unit that generates an air current, a dust collector, and a controller for controlling the air current from the indoor unit. A moving body detector is provided to detect a moving body such as, for example, a person, a pet, a cleaning robot, and the like. The air current from the indoor unit is controlled by the controller based on the position of the indoor unit, the position of a spot of occurrence of dust detected by the moving body detector, and the position of the dust collector such that the air current from the indoor unit reaches the dust collector via the spot of occurrence of dust in order for the dust collector to effectively suck the dust.

  • Patent number: 8138949
    Abstract: In an electronic toll collection system, card data of a payment card is stored in an on-board unit mounted in a vehicle. Toll data necessary for a toll collection transaction including the card data is copied from the on-board unit to a cellular phone. A user passes the cellular phone to a tollgate attendant, and the toll data is moved to a toll collection unit installed at a tollgate. The toll collection unit calculates a toll fee based on the toll data and generates a delete command and road use data. When the tollgate attendant passes a portable terminal of the toll collection unit to the user, the delete command and the road use data are copied to the on-board unit. The toll data is deleted from the on-board unit by the delete command, and the road use data is reported to the user.

  • Publication number: 20100145776
    Abstract: The in-vehicle apparatus card information stored in a storage section is set to an inactive state and is prevented from being read from the storage section when an ignition switch changes from “on” to “off” or when a user performs an operation signifying a change from an active state to the inactive state. Accordingly, the in-vehicle apparatus card information is disabled by an explicit user operation or a normal operation performed when the user gets out of a vehicle. It is possible to prevent the unauthorized use of the in-vehicle apparatus card information when the user does not get in the vehicle.

  • Publication number: 20080243388
    Abstract: An autonomous driving apparatus includes: an obstacle detecting unit for detecting a presence of an obstacle or judging a distance to the obstacle; a driving unit for driving a main body; and a control unit for changing a moving direction of the main body by controlling the driving unit based on obstacle information from the obstacle detecting unit, wherein the control unit has a reciprocating mode in which the main body is reciprocatively moved within a moving area while being also moved in a direction normal to a reciprocating direction. If the control unit judges that the main body is in a movement-stuck state in which movement of the main body is stuck within a movement-stuck area by an obstacle placed in the moving area, the control unit switches the reciprocating mode to an obstacle avoiding mode in which the main body escapes from the movement-stuck area.

  • Patent number: 7385496
    Abstract: A monitoring system for preventing crime in a home, includes a plurality of terminals for monitoring whether predetermined monitoring points are in a stationary or nonstationary state. Further, the monitoring system includes a central processing device for controlling the setting/canceling of alarm operations of the terminals. The central processing device has a communication unit that receives stationary/nonstationary information from the terminals and transmits predetermined information including commands to the terminals. Each terminal has a communication unit that transmits stationary/nonstationary information to the central processing device and receives the predetermined information from the central processing device. Thus bidirectional communication can be achieved between the central processing device and the terminals.

  • Publication number: 20080056495
    Abstract: A wireless communication system provides a decryption module for decrypting card information on a roadside unit for information registration and a roadside unit for toll collection instead of providing the decryption module on a vehicle unit. In this manner, the wireless communication system can accommodate an IC card that uses a new encryption method more easily relative to a conventional wireless communication system, because the roadside units are smaller in number in comparison to the vehicle units at the time of system operation with greater allowance for demand for space efficiency and cost reduction.

  • Patent number: 7082841
    Abstract: An ultrasonic flowmeter includes a transmission/reception means provided in a flow path for performing transmission/reception using a state change of fluid; repetition means for repeating the transmission/reception; time measurement means for measuring a time of propagation repeated by the repetition means; flow rate detection means for detecting a flow rate based on a value of the time measurement means; and number-of-times change means for changing to a predetermined number of repetition times. With such a structure, an influence caused by a variation of a flow can be suppressed by changing the number of repetition times so as to be suitable for a variation. As a result, reliable flow rate measurement with a high accuracy can be achieved.

  • Patent number: 6772643
    Abstract: A flow meter measures a flow rate of fluid flowing through a flow passage based on a duration of propagation of an ultrasonic wave along the flow passage. A signal of the received ultrasonic wave is then compared with a reference voltage to detect an arrival of the ultrasonic wave. A voltage setting unit determines the reference voltage to an appropriate level according to a signal output from a propagation measuring unit which measures a duration of propagation of the ultrasonic wave along the flow passage from the start of transmission of the ultrasonic wave to the output of a signal from a judging unit as the reference voltage being changed. The reference voltage is determined readily and accurately, the flow meter measures the flow rate with the appropriate reference voltage.
