Stationary height measuring and scribing apparatus for use by hearing impaired people for three-dimensionally measuring position of object and marking workpiece, has acoustic and visual transmitter producing signal when set point is probed

摘要

The apparatus has a measuring and scribing instrument (3) whose position is directly and indirectly directed to a computer (1) with a computer program through a measuring instrument for determining and storing measurements. An acoustic and visual transmitter produces signal when a set point is reached or probed manually via a key on the computer program. The signal is transmitted between the headset/earphone and the transmitter through Bluetooth. A headset/earphone is used as a receiver.
