摘要： A programmable accountability apparatus for installation into a vending machine is disclosed. The accountability apparatus comprises a plurality of monitoring wires attachable to points within the vending machine carrying AC signals selected for monitoring, means for converting the AC signals into digital signals, a microprocessor which is programmed to monitor and collect data from the digital signals, and a memory for storing both data collected from the digital signals and data for programming the microprocessor. The data for programming the microprocessor comprises a selected digital word for each monitoring wire which determines whether the occurrence of the AC signal monitored by that wire is to be counted, timed or measured in duration.
摘要翻译：公开了一种用于安装到自动售货机中的可编程问责设备。责任追究机构包括可连接到自动售货机内的点的多个监控线，其携带选择用于监控的AC信号，用于将AC信号转换为数字信号的装置，被编程为从数字信号监视和收集数据的微处理器，以及用于存储从数字信号收集的数据和用于编程微处理器的数据的存储器。用于编程微处理器的数据包括用于每个监控线的所选择的数字字，其确定是否在该持续时间内计数，定时或测量由该线监视的AC信号的发生。

摘要： Continuous power and a high rate clock are supplied to a calculator while it is in an execute mode and is actually decoding and processing input information, but lower duty cycle power and lower duty cycle clock pulses are supplied during the subsequent display mode, when the only requirement is to maintain and display selected information resulting from the execute cycle, so as to reduce the power consumption rate as compared to the rate during the execute mode. If there is no new execute mode within a selected time interval, the display is turned off and the duty cycle of the power and the clock supplied to the calculator are lowered still further so as to maintain (without displaying) selected stored information but to further reduce the rate of power consumption.
摘要翻译：连续功率和高速率时钟在处于执行模式时被提供给计算器，并且实际上是解码和处理输入信息，但是在随后的显示模式期间提供较低的占空比功率和较低的占空比时钟脉冲要求是维护和显示从执行周期产生的所选择的信息，以便与执行模式期间的速率相比降低功耗率。如果在所选择的时间间隔内没有新的执行模式，则显示被关闭，并且提供给计算器的电源和时钟的占空比进一步降低，以便维持（不显示）选择的存储信息，但是进一步降低功耗。
