The preset invention is directed to a building energy management system and method, more specifically to a building energy management system and method that can quickly detect and control an abnormal situation or an emergency situation that may occur within a building.

Examples of techniques for monitoring a component used in well operation are disclosed. In one example implementation according to aspects of the present disclosure, a method may include: receiving, by a processing system, sensor data from a sensor, wherein the sensor collects data relating to a component used in the well operation; analyzing, by the processing system, the sensor data to determine whether the component used in the well operation is experiencing an error condition; and alerting, by the processing system, a user of the error condition when it is determined that the component used in the well operation is experiencing an error condition.

Techniques are disclosed for providing anti-theft protection for power tools. In one example of the techniques of the disclosure, at least one processor of a power tool receives, from an operator, a command to operate the power tool. In response to receiving the command, the at least one processor determines whether at least one of a value of a master authentication counter of the power tool and a value of a user authentication counter of the power tool has reached a predetermined threshold. In response to determining that the at least one of the value of the master authentication counter and the value of the user authentication counter has reached a predetermined threshold, the at least one processor disables the power tool.

A method of programming a power tool includes: establishing a wireless communication link between a power tool and an external computing device having a processor; receiving on the external computing device and from the power tool a first profile associated with a working parameter for controlling an operation of the power tool; displaying, on a display of the external computing device, a graphical representation of the working parameter; receiving a user input at the external computing device to change the working parameter from the first profile to a second profile; transmitting the second profile from the external computing device to the power tool; and programming the power tool to adjust the working parameter in accordance with the second profile.

An adaptive hydraulic control system controls irrigation system zones using predicted valve behavior, measured pressure, recovery time, and measured flow. A pressure sensor can measure a pressure in a water line and a flow meter can measure a flow rate in the water line. The adaptive hydraulic control system monitors the pressure and the flow rate, and determines when the pressure and the flow rate are above and below target operational thresholds. When the pressure is determined to be below a minimum target threshold or the flow rate is determined to be above a maximum target threshold, the adaptive hydraulic control system identifies one or more valves in an opened position of the plurality of valves that when closed would cause the pressure and the flow rate to return within the target operational thresholds. The adaptive hydraulic control system provides instructions to change a position of the one or more identified valves.
