Apparatus and system for monitoring tool use
First Claim
1. A system for monitoring usage of one or more power tools, the system comprising:
- a setting assembly configured to set a prescribed extent of usage of a tool, the prescribed extent being determined by conversion of usage units into time units using a conversion function specific to the tool, wherein the conversion function is dependent upon operational characteristics of the tool;
a sensor configured to sense a usage of the tool;
a timer configured to time a duration of usage of the tool in accordance with the sensor; and
,a controller configured to provide an indication when the timed duration of usage of the tool reaches or exceeds the prescribed duration.

Abstract
An apparatus and system for monitoring usage of one or more power tools, the system comprising setting means by which a prescribed extent of usage of a tool can be set. The prescribed extent of usage is determined by conversion of usage units into time units using a conversion function specific to said tool, wherein the conversion function is dependent upon operational characteristics of said tool. The apparatus or system further comprise sensing means for sensing usage of a tool, timing means for timing the duration of usage of the tool in accordance with said sensing means, and control means arranged to provide indication when the timed duration of usage of said tool reaches or exceeds the prescribed duration.
