  • Power saving technique for pulse-echo acoustic ranging systems
    Patent number: 6621763
    Abstract: A power saving system and method for the analog-to-digital converter stage in a time of flight ranging system. A receiving echo signal having an envelope is converted into a digital form suitable for further processing by sampling the received echo signal envelope at precise intervals to obtain amplitude measurement points. An interpolation function is applied between each pair of adjacent amplitude measurement points. The application of the interpolation function provides a closer approximation of the shape of the received echo signal envelope without the need to use higher sampling rates which means slower analog-to-digital converters may be utilized resulting in power and cost savings.

  • Transmission
    Patent number: 6619450
    Abstract: A transmission for changing a ratio of a rotational number of a power source and a rotational number of an output shaft by shifting a gear train provided between the power source and the output shaft by moving a shift fork. The transmission includes a shift drum for moving the shift fork, a clutch provided between the power source and the gear train, a shift spindle for urging the shift drum and the clutch. When the shift spindle is pivoted, lift of a clutch is started by pivoting a clutch arm. In accordance with pivoting the shift spindle, a sub arm is pivoted and preload is applied on a master arm by a preload spring. Thereafter, when the sub arm is further pivoted, the master arm follows the sub arm and a shift drum is pivoted via index pins. Since the preload is applied, when the clutch is disengaged, the shift drum is pivoted immediately, a shift fork is displaced and gears are switched.

  • Tiled phased array antenna
    Patent number: 6621470
    Abstract: A phased array antenna consisting of like multi-element tiles whose elements are located so as to produce an irregular array when the tiles have mutually different orientations, e.g., random. The resulting irregular array reduces the effective translational period of the array elements, which in turn ameliorates grating lobes even for wide (one wavelength) effective element spacings. An antenna so designed can maintain low peak sidelobes at far higher frequencies than a conventional translational-periodic phased array antenna of the same element density.

  • Belt replacement timing annunciator for belt-type automatic transmissions
    Patent number: 6622072
    Abstract: To improve the maintainability of a vehicle by properly identifying a worn endless belt in a belt-type automatic transmission and informing a driver of the proper belt replacement interval. The belt replacement timing annunciator relies upon the radii of the endless belt wound around a drive pulley and around a driven pulley that vary to produce shifting change gear ratios. Various operating conditions and the actual change gear ratio for the specific operating condition are detected, and a comparison between a reference change gear ratio and the actual change gear ratio is made to determine if belt replacement is necessary. A timer device provides a predetermined observation interval for avoiding erroneous readings and a display is also provided for indicating the necessity of belt replacement.

  • Printing service system
    Patent number: 6619868
    Abstract: At the time of placing an order for printing image data via a network, the order can be efficiently rerouted in the case where a printing service provider designated according to an agency specified by a user cannot process the order. A database in a service center stores a laboratory information table. The printing service provider registers with the laboratory information table in advance the printing services available thereat and rerouting information to automatically send order information representing processing that cannot be processed by the printing service provider, such as large-size printing and postcard printing, to another printing service provider. An order reception server judges the content of order information sent from the user and sends the order information to the printing service provider designated by the rerouting information in the laboratory information table if necessary.
