摘要： A lifting tool has a handle, a lifting tool head, and a means for slidably mounting the lifting tool head on the handle such that the lifting tool head slides with respect to the handle between an extended position and a compressed position. The lifting tool further includes a means for biasing the lifting tool head towards the extended position. Since the lifting tool head can slide against the bias of the means for biasing, the lifting tool can absorb some of the shock if the lifting tool head strikes a hard obstruction, thereby sparing a user from the strain and potentially avoiding an injury that could result from the strain.

摘要： An information tracking device has a bottom disk, a middle marker element, a top disk, and a locking element. The bottom disk has a top surface and a perimeter with a first plurality of information indicia imprinted on the top surface adjacent the perimeter. The middle marker has a marking element. The top disk includes an upper surface with a second plurality of information indicia imprinted on the upper surface. The locking element releasably locks the bottom disk, the middle marker, and the top disk together such that the middle marker indicates a selected one of the first plurality of information indicia and a selected one of the second plurality of information indicia.

摘要： A tracking device for tracking the ingestion of a plurality of doses of an ingestible material from a container has a time indicating sheet and a plurality of dose indicators. A plurality of time indicating indicia is imprinted on a top surface of the time indicating sheet, each of the plurality of time indicating indicia being spatially separated from each other on the top surface and being adapted to indicate a time period. The plurality of dose indicators each have printed on an upper surface one of a plurality of dose identifying indicia and a reference mark that indicates a direction of orientation visible on each of the plurality of dose indicators. A layer of adhesive on a lower surface of the plurality of dose indicators allows the plurality of does indicators to be attached to the top surface of the time indicating sheet such that the reference mark visibly indicates a direction of orientation that is associated with one of the plurality of time indicating indicia.
摘要翻译：用于跟踪从容器摄取多个剂量的可摄取材料的跟踪装置具有时间指示片和多个剂量指示器。多个时间指示标记被印在时间指示纸的顶表面上，多个时间指示标记中的每一个在顶表面上彼此空间上分离，并适于指示时间段。多个剂量指示器各自已经在多个剂量识别标记的上表面上印刷了指示在多个剂量指示剂中的每一个上可见的取向方向的参考标记。在多个剂量指示器的下表面上的一层粘合剂允许多个指示器附着到时间指示纸的顶面，使得参考标记可视地指示与其中之一相关联的取向方向多个时间表示标记。
