Abstract: A method according to a first aspect may include performing a first analog-to-digital (A/D) conversion using an A/D converter. Data associated with this first A/D conversion may be read using a processor. A command may then be issued from a processor when the reading of the data has started. This command may instruct the A/D converter to perform a second A/D conversion. This data may then be stored in a data structure located within a memory device while the A/D converter is performing the second A/D conversion. In addition to performing such pipelined A/D conversions, the present invention may include a system, method and software for filtering out noise in a voltage measurement after the voltage measurement has been converted to a digital signal by omitting the highest and lowest voltage values and averaging the remainder of the voltage values, thereby reducing noise in the voltage measurements.

Abstract translation: 根据第一方面的方法可以包括使用A / D转换器执行第一模数（A / D）转换。 可以使用处理器读取与该第一A / D转换相关联的数据。 然后，当数据的读取开始时，可​​以从处理器发出命令。 该命令可以指示A / D转换器执行第二次A / D转换。 然后可以在A / D转换器执行第二A / D转换的同时将该数据存储在位于存储器件内的数据结构中。 除了执行这样的流水线A / D转换之外，本发明可以包括用于在通过省略最高和最低电压值将电压测量转换成数字信号之后滤除掉电压测量中的噪声的系统，方法和软件，以及 平均剩余的电压值，从而降低电压测量中的噪声。
