Power tool e.g. drilling machine, has working filed light e.g. LED, provided for optically, haptically and acoustically displaying status of parameter lying outside predetermined limit, where filed light is controlled using microprocessor

摘要

#CMT# #/CMT# The power tool (1) has a monitoring unit (10) monitoring a parameter of the tool. An electric motor (2) is provided for operating the tool. A switch (5) is arranged on a housing (4) of the tool. A working filed light (9) e.g. LED, is provided for optically, haptically and acoustically displaying a status of the parameter lying outside a predetermined limit, where the filed light is controlled using a microprocessor (8). The display is controlled by changing color and illumination of the filed light. #CMT#USE : #/CMT# Power tool e.g. battery and mains-operated power tool such as drilling machine, grinder, saw, planer and angle grinder (all claimed). #CMT#ADVANTAGE : #/CMT# The working filed light e.g. LED, is provided for optically, haptically and acoustically displaying the status of the parameter lying outside the predetermined limit, where the filed light is controlled using the microprocessor, thus providing visual display for the power tool in a simple manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a side view of a power tool. 1 : Power tool 2 : Electric motor 4 : Housing 5 : Switch 8 : Microprocessor 9 : Working filed light 10 : Monitoring unit.
