Abstract: The present subject matter is directed to a method for estimating rotor blade loads, e.g. a blade root resultant moment, of a wind turbine. In one embodiment, the method includes measuring, via one or more sensors, a plurality of operating parameters of the wind turbine. Another step includes estimating out-of-plane and in-plane forces acting on the rotor blade based at least partially on the plurality of operating parameters. Further, the method includes determining an application point for the out-of-plane and in-plane forces along a span of the rotor blade. A further step includes estimating out-of-plane and in-plane moments of the rotor blade based at least partially on the out-of-plane and in-plane forces and the respective application points. Thus, the method includes calculating the load acting on the rotor blade based at least partially on the out-of-plane and in-plane moments.

Abstract: A charged particle beam device (10) is provided, including a computer operable in response to commands entered by a user of the device to control the device, wherein the device further includes an interface (24) operable to cause data from the computer in the form of short message service (SMS) and/or multimedia message service (MMS) messages to be transmitted to a mobile device (16, 18, 20) via a mobile telephone network (14). The charged particle beam device (10) is operable to receive commands in the form of SMS and/or MMS messages from the mobile telephone (14), and to cause the computer to execute the commands.

Abstract: An electro-mechanical slide out locking mechanism (EMSOLM) is disclosed that can lock a slide out unit of a mobile structure. In a particular embodiment the EMSOLM can have a rigid member that is connected to a transmission and an actuator. The actuator could be an electric motor, a solenoid or any other device that can convert electrical energy into mechanical movement. The actuator can have a mounting surface that is clamped or connected to a recreational vehicle or a slide out unit. The actuator can drive the transmission to move the rigid member in relationship to the mounting surface. The actuator can be connected to a switch via wires and the switch can be connected to a power system or batteries. Activating the switch can move the rigid member into position such that is locks the slide out unit in an extended or retracted position.
