Document Type and Number:
WIPO Patent Application WO/2020/073219
Kind Code:
A1
Abstract:
A laser level (21) containing a housing (20), an electronic tilt sensor (32) located in the housing (20); a controller (30) to which the electronic tilt sensor (32) is connected, and a laser module (36). The controller (30) is communicable with a first display device (24) and a second display device (26). The laser module (36) is adapted to project a straight ground laser line on a flat surface. The electronic tilt sensor (32) is adapted to detect a tilt of the laser level and provide a measurement signal to the controller (30). The controller (30) is adapted to provide a display signal to the first and second display devices (24, 26) to display information about the tilt. By using an electronic tilt sensor (32), the laser level (21) can provide accurate indicate of the tilt of the device and also allows such tilt information to be processed further.
