    • A timing device for tracking the length of time a user is absent from a particular location comprises a base member that includes a housing, a timer mounted to the housing, a display connected to the timer, and a timing-key receiver attached to the housing and in communication with the timer and utilized in starting and stopping the timer. Provided is a visually prominent timing-key releasably mountable to the timing-key receiver that comprises a key body and a coupler attached to the key body which releasably mates with the timing-key receiver. The device is commonly employed in tracking how long a student is temporarily absent from a classroom.
    • 用于跟踪用户不在特定位置的时间长度的定时装置包括基座构件,其包括壳体,安装到壳体的定时器,连接到定时器的显示器以及附接到壳体的定时键接收器 并与定时器通信并用于启动和停止定时器。 提供了一种视觉上突出的定时键,其可释放地安装到定时键接收器,该定时键接收器包括键体和连接到键体上的耦合器,其可释放地与定时键接收器配合。 该设备通常用于跟踪学生暂时离开教室多久。
