Device for showing elapsed time

An elapsed time and remaining time liquid crystal measuring device having a display face around the periphery of which there are a plurality of numerical indicia marks arranged in a generally clockwise pattern with successive numerical indicia marks decreasing in numerical value in a clockwise direction from a twelve o'clock position. An annular ring of electronically generated graphic indicia are visible on the display face and spaced inwardly from the peripheral numerical indicia and a digital numerical read-out display of elapsed times is visible internally of the annular ring of graphic indicia. There is at least one electronic control element for setting a desired elapsed set time into the device, which desired elapsed set time is indicated both on the digital read-out display and as a complete ring or an arcuate section of the annular ring on the display face. There is also an actuator for initiating progressive clockwise disappearing movement of the electronically generated graphic indicia so as to expose decreasing areas of the annular ring in a clockwise direction as time elapses and while the digital numerical display remains synchronized with the graphic indicia until all of the set time has elapsed. Preferably, the device is in the form of a wrist watch.

Face of time display device

A time teaching aid for teaching the concept of remaining time and elapsed time comprises a stationary face with a plurality of numerical indicia marks arranged around the face in a generally clockwise pattern, and successive indicia marks decreasing in value in a clockwise direction from a twelve-o'clock position. A rotating face rotates in the clockwise direction on the stationary face and exposes a portion thereof in front of the stationary face during rotation. A time hand rotates in synchronization with the rotating face and points to the numerical indicia marks on the stationary face. The rotating face exposes an ever decreasing portion thereof during clockwise rotation and the time hand progresses in a clockwise fashion from the twelve-o'clock position, through the numerical indicia marks, and back to the twelve-o'clock position, such that the ever-decreasing exposed portion corresponds to the time hand pointing to decreasing values of the numerical indicia whereby to simultaneously indicate to a viewer the decreasing time remaining both proportionately and numerically on the stationary face.
