20190232450 | DRIVE UNIT - A drive unit having a transport element has at least one entrainer engaging into a drive groove of a barrel cam, an electrical drive device, and a base control device that is adapted to receive control signals for the operation of the drive unit from a user interface programmable by an operator and to output a drive signal to the drive device in dependence on a received control signal. The drive device is adapted to drive the barrel cam to make a rotational movement and thus to drive the transport element in response to the drive signal. The base control device is further adapted to selectively operate the drive device in a full operation mode or, if no control signal is received after the output of a drive signal and after the elapse of a cycle time duration of the drive unit, to set it into a standby operation mode in which an electrical supply of the drive device is interrupted. | 2019-08-01 |
20190232451 | MEASUREMENT, LAYOUT, MARKING, FIRESTOP STICK - Multiple cameras are used for tool positioning, as-built documentation, and/or personnel monitoring in construction site. A camera unit comprises one or more imaging devices, a processing computer, and a communication device. The camera units are placed at multiple locations in a construction site to cover an area. The camera units are self-positioned by detecting a calibration target that moves within a working volume. The camera units can detect and calculate positions of objects, including measurement sticks, tools, personnel, etc., in the area. | 2019-08-01 |
