摘要： A time recorder receives bar coded time cards, punches time data on the cards and stores the time data in memory. Each card has a bar code at each end corresponding to the same value. For each pay period, a unique bar code and the card on which it is printed are assigned to each employee during an initialization process. A card is inserted upside down into the time recorder for each employee and the bar code is read by the system and assigned to an employee. At the same time, employee information is printed on the card.

摘要： A readout circuit for determining the displacement of a magnet relative to a fixed reference point is disclosed. The relative displacement is determined by measuring the time interval required for a stress wave created in a magneto-strictive probe adjacent to the magnet to travel to the reference point. The readout circuit includes a counter means for counting at a predetermined rate. In order to determine the displacement of the magnet using the readout circuit, a pulse signal is generated in the probe causing a stress wave to be created in the probe at the location of the magnet. The counter means of the circuit is then activated in timed relation to the generation of the pulse signal. A means for detecting the arrival of the stress wave at the reference point and for stopping the counter means when the wave is detected is also provided in the readout circuit. By measuring the travel time for the stress wave with the readout circuit, the displacement of the magnet is determined. The fixed reference point may be either the end of the probe, or a reference magnet adjacent to the probe.
摘要翻译：公开了一种用于确定磁体相对于固定参考点的位移的读出电路。通过测量在与磁铁相邻的磁致伸缩探测器中产生的应力波行进到参考点所需的时间间隔来确定相对位移。读出电路包括以预定速率计数的计数器装置。为了使用读出电路确定磁体的位移，在探针中产生脉冲信号，导致在磁体位置处的探头中产生应力波。然后电路的计数器装置以与产生脉冲信号的定时关系来启动。在读出电路中也设置有用于检测应力波在基准点的到达和用于在检测到波时停止计数装置的装置。通过用读出电路测量应力波的行进时间，确定磁体的位移。固定参考点可以是探头的末端，也可以是与探头相邻的参考磁体。
