    • A system for time-sequential LED-string excitation includes a controller coupled to at least two LED strings and arranged to sequentially excite the strings—preferably by pulse-width modulating their respective currents—such that each string conducts a desired current and/or provides a desired light intensity. Individual string currents and/or light intensities are provided to the controller as feedback signals. The controller preferably pulse-width modulates each string such that it conducts a current which approximates the performance that would be provided if the string were made to continuously conduct an ‘optimal’ current. A voltage converter may be included to provide the supply voltage connected to the top of each LED string, and to adjust the supply voltage as needed to ensure that each string conducts a desired current.
    • 用于时序LED串激励的系统包括耦合到至少两个LED串并被布置成顺序地激励弦的控制器 - 优选地通过脉冲宽度调制它们各自的电流 - 使得每个串传导期望的电流和/或提供 期望的光强度。 将单独的串电流和/或光强度作为反馈信号提供给控制器。 控制器优选地对每个串进行脉冲宽度调制,使得它传导近似如果使串被连续地导通最佳电流时提供的性能的电流。 可以包括电压转换器以提供连接到每个LED串的顶部的电源电压,并且根据需要调整电源电压以确保每个串传导期望的电流。

    • An IC monitoring chip (10) for remotely monitoring the output of a thermal diode (5) formed in the substrate of a CPU (2) for monitoring the temperature of a thermal plate (3) of the CPU (2) comprises a signal conditioning circuit (12) which relays the output from the diode (5) to an analog-to-digital converter (14), which in turns outputs a two's compliment signal to an adder (22). The adder (22) adds the two's compliment signal to a temperature offset value stored in a temperature offset register (17), which compensates for the temperature difference between the diode (5) and the thermal plate (3). Comparators (24) and (25) compare the output from the adder (22) with upper and lower predetermined temperature limits in upper and lower limit registers (19) and (20) for determining the temperature of the thermal plate (3). The temperature offset value is stored in ROM (35) of the computer (1) and is written to the register (17) each time the computer (1) is powered up. The IC chip (10) operates independently of the CPU (2).
