A construction site status monitoring device is provided including processing circuitry configured to receive sensor data from a sensor associated with one or more construction devices, receive location data associated with the one or more construction devices, and generate a construction site status report based on the sensor data and the location data, wherein the construction site status report is indicative of conditions and location of the one or more construction devices.

Device for real time equipment tracking at a construction site

A construction device scheduling device is provided including processing circuitry configured to receive device identifiers associated with a plurality of construction devices, receive a construction plan, and determine a construction device schedule based on the device identifiers of the plurality of construction devices and the construction plan.

Device for determining a construction device schedule

A construction site status monitoring device is provided including processing circuitry configured to receive construction device location data associated with a construction device, receive worker location data associated with a worker, and determine a safety condition based on the construction device location data and the worker location data.

Device for determining construction device and worker position

A construction site status monitoring device is provided including processing circuitry configured to receive teaching data from a construction device in a teaching mode based on an operator performing an operation with the construction device and generate an operation profile based on the teaching data for execution by one or more construction devices. The operation profile defines parameters associated with the operation to enable one or more construction devices to repeat the operation in an operate mode.

Teaching mode for construction devices

A construction site status monitoring device is provided including processing circuitry configured to receive a battery identifier data associated with respective construction device batteries of a plurality of construction device batteries, receive location data associated with the respective construction device batteries of the plurality of construction device batteries, and determine a substitute battery from the plurality of construction device batteries for a construction device battery of the plurality of construction device batteries based on the battery identifier data or the location data.

Identifying and locating a substitute battery for a construction job site power tool

A construction site status monitoring device comprising processing circuitry configured to generate a construction device availability request including an indicator of a device type, in response to an initiating event including an indicator of a device type, and receive a construction device availability response including location data and status information of at least one available construction device of the device type based on the construction device availability request.

Locating substitute construction tools within a construction worksite

An electric motor () having a motor control system () including: &#x2014;a current measuring means () for directly or indirectly measuring the electric current in the rotor windings () providing a rotor current value/s, &#x2014;an ambient temperature measuring/estimation means () for measuring or estimating the ambient air temperature providing an air temperature value/s, &#x2014;a rotor temperature estimation means () for estimating a rotor temperature at least based on the rotor current value/s and the air temperature value/s, and&#x2014;a current limiting means () for preventing overheating/burning of the rotor assembly () by limiting the electric current to the rotor windings () when the estimated rotor temperature exceeds a predetermined overheating threshold ().

Electric motor and method for controlling the same

According to an embodiment, a leveling aid () for a drilling tool () is disclosed. The leveling aid () includes a mounting means adapted to be attached to the drilling tool (). The leveling aid () further includes a level detecting device adapted to provide information of inclination of the mounting means. In particular, the level detecting device is suspended on the mounting means via a resilient assembly. The resilient assembly is adapted to absorb vibrations from the drilling tool () to the level detecting device.
