    • An impact printer is provided which is capable of printing at either 10 characters per inch (standard pitch) or 15 characters per inch (compressed pitch) by changing the type character carrying member, such type carring member including multiple font character sets thereon. The type character carrying members or bands include timing marks thereon for detecting or sensing the type band (standard or compressed pitch), the type character font set, and for tracking the type characters on the band. The printer also includes time shared hammer means which are movable or shifted a precise distance of 1/10 inch for a standard pitch band or a precise distance of 1/15 inch for a compressed pitch band, such movement being operable by control mechanism responsive to pulses derived from the timing marks relative to the horizontal position mechanism and the type band on the printer (standard or compressed pitch).
    • 提供一种冲击式打印机,其能够通过改变类型字符承载构件来以每英寸10个字符(标准间距)或15个字符每英寸(压缩间距)进行打印,这种类型的挂钩构件包括多个字体字符集。 类型字符携带构件或带包括用于检测或感测类型频带(标准或压缩音调),类型字符字体集合以及用于跟踪频带上的类型字符的定时标记。 打印机还包括时间共享锤装置,其可移动或移动1/10英寸的精确距离用于标准间距带或1/15英寸的精确距离用于压缩音调带,这种移动可由控制机构操作,响应于 从定时标记相对于水平位置机构和打印机上的类型带(标准或压缩间距)产生的脉冲。

    • A data logging system includes a data logging unit, a primary power source, an auxiliary power source and a controller. The controller detects whether the primary power source is available or unavailable and the time at which it became available or unavailable. From the time data the controller will then determine the total time the primary power source was unavailable to power the system. The controller adjusts or increases a predetermined auxiliary power source value by the auxiliary power source usage time period. Upon each occurrence in which the primary power source again becomes unavailable, the controller performs the same operations and further adjust or increases the previously reduced predetermined auxiliary power source value by the next auxiliary power source usage time period. Adjusting or increasing the predetermined auxiliary power source value will continue until a predetermined value is reached which triggers an alert. The alert indicates to an operator that the system requires service.
    • 数据记录系统包括数据记录单元,主电源,辅助电源和控制器。 控制器检测主电源是可用还是不可用,以及可用或不可用的时间。 从时间数据开始,控制器将确定主电源不能供电的总时间。 控制器通过辅助电源使用时间周期来调整或增加预定的辅助电源值。 在主电源再次不可用的情况下,控制器执行相同的操作,并且通过下一个辅助电源使用时间段进一步调整或增加先前减小的预定辅助电源值。 调整或增加预定的辅助电源值将继续,直到达到触发警报的预定值。 该警报向操作员指示系统需要服务。
