    • A battery charger with charging parameter values derived from communication with a battery pack to be charged. Communication is over a one-wire bus with battery pack transmissions in response to charger inquiries. The battery charger may be in the form an integrated circuit driving a power transistor or other controllable DC supply. A battery pack may contain a program with multiple charging currents and charging interval termination methods such as time, temperature rise, and incremental voltage polarity. A lack of communication may be invoke a default charging program or denial of access to the charger. The charger also communicates over a high-speed three-wire bus with an external computer for analysis of identification information acquired from the battery and for control of the charger.
    • 带充电参数值的电池充电器来自与要充电的电池组的通信。 响应充电器查询,通信是通过电池组传输的单线总线。 电池充电器可以是驱动功率晶体管或其他可控直流电源的集成电路。 电池组可以包含具有多个充电电流和充电间隔终止方法的程序,例如时间,温度升高和增加的电压极性。 缺乏通信可能会引起默认的计费程序或拒绝访问充电器。 充电器还通过高速三线总线与外部计算机进行通信,用于分析从电池获取的识别信息和控制充电器。

    • An electronic key which responds to different sets of valid commands over its lifetime, depending on the state of certain circuits within the electronic key.(1) After initial fabrication of the electronic key, the electronic key recognizes a first set of valid commands and ignores all other commands.(2) After the electronic key is tested and a countdown circuit within the electronic key has been calibrated, a fusing element inside the electronic key is blown. This reduces the number of valid commands recognizable by the electronic key. Thus, the key is now restricted to a second set of valid commands.(3) The electronic key is then shipped to an OEM, who programs data into the key and also programs the length of time of the countdown timer. The OEM then sets an R-S flip-flop in the electronic key, which causes certain of the second set of commands to be ignored. Thus, the key will now respond only to a third set of valid commands.(4) The electronic key is then shipped to an end user. The first valid command recognized by the electronic key, after the R-S flip-flop has been set, starts the countdown timer.(5) After the countdown timer has timed out, the number of valid commands is further reduced. Thus, the key will now respond only to a fourth (very small) set of valid commands.
    • 一种电子钥匙,它根据电子钥匙内某些电路的状态,在其使用寿命期间响应不同的有效命令集。 (1)电子钥匙的初始制造后,电子钥匙识别第一组有效命令,并忽略所有其他命令。 (2)在电子钥匙被测试并且电子钥匙内的倒计时电路已被校准之后,电子钥匙内的定影元件被吹动。 这减少了电子钥匙可识别的有效命令的数量。 因此,密钥现在被限制到第二组有效命令。 (3)电子钥匙然后发运给OEM,他们将数据编入密钥,并对倒数计时器的时间长度进行编程。 然后,OEM在电子钥匙中设置一个R-S触发器,这导致第二组命令中的某些被忽略。 因此,密钥现在将仅响应第三组有效命令。 (4)电子钥匙然后运送到最终用户。 在电子钥匙识别的第一个有效指令,在R-S触发器置1之后,启动倒数计时器。 (5)倒数计时器超时后,进一步减少有效命令的数量。 因此,密钥现在将仅响应第四(非常小)的有效命令集。

    • A timeout circuit with internal calibration includes an oscillator (11) for generating an initial frequency for division by a modulo-n counter (20). The counter (20) receives the value of n from a calibration register (22) and divides the frequency of the oscillator by the value of n. A gate (26) prevents alteration of the contents of the register (22). The output of the counter (20) provides a calibrated frequency which is further divided by a day counter (32) for output to a countdown counter (34). The countdown counter (34) provides a predetermined countdown of the signal output by the day counter (32) and, at the end of the count, generates a Timeout signal. The predetermined countdown value is determined by a value stored in a register (36) which can be protected by a customer lock out circuit (42).
    • 具有内部校准的超时电路包括用于产生用于由模n计数器(20)划分的初始频率的振荡器(11)。 计数器(20)从校准寄存器(22)接收n的值,并将振荡器的频率除以n的值。 门(26)防止寄存器(22)的内容的改变。 计数器(20)的输出提供校准频率,进一步由日间计数器(32)除以输出到倒数计数器(34)。 倒计时计数器(34)提供由日间计数器(32)输出的信号的预定倒计时,并且在计数结束时产生超时信号。 预定的倒计时值由存储在可由客户锁定电路(42)保护的寄存器(36)中的值确定。
