Visual aid timer systems comprise a visual aid timer that may be displayed to users, and synchronized to an audible alert signal providing expirations of time intervals and/or indications of start and/or stop times in a plurality of intervals used in physical fitness training and/or testing. The visual aid timer system provides a visual indication of time remaining in each of the plurality of intervals for viewing by users thereof. Methods of using the same are further provided.

Approaches describe a mobile computing device, e.g., an ergonomically configured connected counting device, to capture counts of people, products, or any countable object, store the counts and associated information in a central repository for access by other connected counting devices. The counts and associated qualifying information can then be displayed through mobile devices and web applications, and can display count data with sales, demographic and other qualifying data sources to provide information for qualitative and quantitative reporting, as well as enable count based automated promotions through traditional channels and social networks.

An electronic bead string includes a main bead, a plurality of secondary beads, a displacement sensor, a memory, and a processor. The main bead and the secondary beads are strung together to form a bead string. The displacement sensor is fixed in the main bead to output two-dimensional displacement signals, the memory stores the two-dimensional displacement signals, and the processor determines whether a rotation cycle of the electronic bead string is an approved rotation cycle according to the two-dimensional displacement signals.

Provided is a threaded member tightening tool capable of returning a count value in linkage with reverse driving by the threaded member tightening tool and only when a threaded member to be removed by the reverse driving has been counted as a tightened threaded member. A computing unit of a motor-driven screwdriver is switchable between a counting mode in which the computing unit counts the number of tightened threaded members and holds the counted number as a count value and a count return mode for returning the count value to a one-preceding count value. The computing unit returns the count value to a one-preceding count value based on the fact that the engaging element fitting unit has been driven in the reverse direction when the computing unit has been switched to the count return mode.

The invention relates to hand pliers (1) which are in particular embodied as crimping pliers. According to the invention, the hand pliers (1) comprise a counting device (16) which counts the number passed working strokes (17). The counting device (16) is built with a sensor which senses the distance or displacement of two components moved relatively to each other over the working stroke (17), in particular the distance or displacement of hand levers (2, 3). If the count number registered by the counting device (16) exceeds a threshold value, it is possible to produce a display at a displaying device of the hand pliers (1) which indicates that an exchange of drive elements or an exchange of dies or a certification of the hand pliers is required.
