Title: AN ELECTRONIC RATIO ADJUSTABLE RULER
Abstract:
There is provided herein an electronic ruler comprising a digital display for the display ratio adjustable ruler representations thereon. The electronic ruler may comprise physical componentry comprising a power supply which may draw power from a USB port to charge a lithium battery which may power a CPU module. The CPU module may control a digital display, such as a thin-film-transistor liquid-crystal display (TFT LCD) display. Furthermore, the CPU module may run an operating system to execute a software application which may be used to dynamically adjust the display of a ruler representation on the digital display. In a preferred embodiment, the digital display runs along an edge of the ruler such that the ruler representation can be read from an edge of the ruler in the conventional manner. The electronic ruler of this particular construction allows for multiple uses according to differing operational modes.
