  • Patent number: 7986978
    Abstract: A hands-free apparatus determines whether there is an incoming call, and then determines whether the incoming call is to be answered by switching from a current call or to be rejected. When the incoming call is determined to be answered, the current call in a hands-free communication is put on hold for switching to the incoming call, and call partner information of the current call is spared from being displayed on a display unit to represent that the incoming call is now being established.
    Type: Grant

    Date of Patent: July 26, 2011
    Assignee: Denso Corporation

  • Publication number: 20070129116
    Abstract: An on-vehicle hands-free system includes an on-vehicle hands-free device that is communicable with a cell phone under both a hands-free profile and other profiles. When a stop trigger is generated by an external switch such as an accessory switch under a condition that the hands-free device is communicable under any of the other profiles, this profile other than the hands-free profile is automatically disconnected so that the hands-free device starts its operation in a normal wait state if a start trigger for starting communication is generated again. Thus, communication with the cell phone under the hands-free profile can be started in a short time after the start trigger.

  • Patent number: 5561630
    Abstract: An improved data sense for a DRAM. Each bit line pair is coupled through a pair of high-resistance pass gates to a sense amp. During sense, the high-resistance pass gates act in conjunction with the charge stored on the bit line pair as, effectively, a high-resistance passive load for the sense amp. A control circuit selectively switches on and off bit line equalization coincident with selectively passing either the equalization voltage or set voltages to the sense amp and an active sense amp load. Further, after it is set, the sense amp is selectively connected to LDLs through low-resistance column select pass gates. Therefore, the sense amp quickly discharges one of the connected LDL pair while the bit line voltage remains essentially unchanged. Thus, data is passed from the sense amp to a second sense amplifier and off chip. After data is passed to the LDLs, the control circuit enables the active sense amp load to pull the sense amp high side to a full up level.
