    • An electronic device such a telephone (100), PDA (600), or pager (800), includes a manually operable input such as an elastomeric key (102, 103) or button (814), or a touch screen (604) that does not by itself provide substantial tactile feedback upon actuation, and also includes an electromechanical transducer (212) that is capable of generating an impulse of mechanical energy that can be felt. In response to detecting actuation of the manually operable input (102, 103, 814, 604), the electromechanical transducer (212) is driven to produce an impulse of mechanical energy that propagates to the manually operable input (102, 103, 814, 604) and provides tactile feedback to a user.

    • The invention describes an apparatus and method for detecting a short circuit to a battery voltage when driving a piezoelectric element, for example, used as an actuator in a fuel injection system of an internal combustion engine. The apparatus and method are characterized in that separate switches are used for selecting a piezoelectric element to be operated and for selecting the operation that is to be performed on the piezoelectric element. A short circuit to battery voltage is detected by first activating the switches to select a piezoelectric element. For a predetermined time interval, the invention monitors for abnormal currents flowing in series with the piezoelectric element. If abnormal currents are detected, an error signal is generated indicating a short circuit to battery voltage. If no abnormal currents are detected during the predetermined time interval, then the switches for selecting a charging or discharging operation are activated to continue with the normal cycling of the piezoelectric elements.
    • 本发明描述了一种用于在驱动压电元件例如用作内燃机的燃料喷射系统中的致动器时检测电池电压短路的装置和方法。 该装置和方法的特征在于,使用单独的开关来选择要被操作的压电元件和用于选择对压电元件执行的操作。 通过首先启动开关来选择压电元件来检测电池电压的短路。 在预定的时间间隔内,本发明监测与压电元件串联流动的异常电流。 如果检测到异常电流,则产生指示电池电压短路的误差信号。 如果在预定时间间隔内没有检测到异常电流,则用于选择充电或放电操作的开关被激活以继续压电元件的正常循环。
