    • The air circulation fan associated with a radiator of some machines may include an automatic reversing purge cycle that is utilized to dislodge material from the radiator and/or intake screen of the cooling system housing. The purge cycle is locked out when a person may be in the vicinity of the air intake screen of the machine. A controller determines that a person may be in the vicinity of the air intake screen when the machine is idle stationary, such as by determining that a parking brake is engaged. By locking out the purge cycle during machine idle stationary conditions, the risk of blowing dislodged dirt and/or debris onto a person, who may be servicing the machine or accessing an operator station, can be avoided.
    • 与一些机器的散热器相关联的空气循环风扇可以包括用于从冷却系统壳体的散热器和/或进气屏幕移走材料的自动换向吹扫循环。 当人员可能在机器进气屏幕附近时,清洗循环被锁定。 当机器怠速静止时,例如通过确定驻车制动器被接合,控制器确定人员可能在吸气屏幕附近。 通过在机器怠速静止条件下锁定清洗循环,可以避免将可能正在维修机器或操作员站的人员吹走掉的污垢和/或碎屑的风险。

    • A current-mode sense amplifier for detecting data stored in a flash memory cell. The sense amplifier has a first current generator for generating a first current to a first circuit according to current flowing out of the memory cell, a second current generator for generating a second current to a second circuit according to current flowing out of a reference cell, and a switch. When the switch is on and a common node of the first circuit and the second circuit is floating, the first and second circuits will generate equal initial voltages. When the switch is off and the common node of the first and second circuits is grounded, one of the initial voltages will increase, and the other initial voltage will decrease.
    • 一种用于检测存储在闪存单元中的数据的电流模式读出放大器。 读出放大器具有第一电流发生器,用于根据流过存储单元的电流向第一电路产生第一电流;第二电流发生器,用于根据从参考单元流出的电流产生第二电流到第二电路; 和开关。 当开关导通并且第一电路和第二电路的公共节点浮动时,第一和第二电路将产生相等的初始电压。 当开关关闭并且第一和第二电路的公共节点接地时,初始电压之一将增加,另一个初始电压将降低。
