METHOD, APPARATUS, AND COMPUTER PROGRAM PRODUCT FOR USE OF LCD DISPLAY IN A CORDLESS TOOL

摘要

Provided are a method, apparatus and computer program product for the use of LCD display in an improved cordless tool having a self-contained power source. The method, apparatus and computer program product provide the operator of a cordless device with an accurate estimate of the remaining charge for performing the last task performed by the cordless device. In this regard, after a task is performed using the cordless tool, the charge consumed by the task is computed. The charge remaining in the self-contained power source is determined. The remaining charge in the power source for performing the same task is then computed based on the computed charge consumed by the task and the charge remaining in the power source. Accordingly, the remaining charge in the power source for performing the same task is actively and more accurately computed and outputted to the LCD display thereby providing an improved cordless tool.
