Abstract: Aspects of the present disclosure include systems, apparatuses, or methods for a system for reducing battery cell failure propagation risk includes a rechargeable battery including a plurality of rechargeable cells connected in series, parallel, or a combination of series and parallel and a BMS coupled with the battery. The BMS includes a processor and a memory including computer-executable instructions to receive information indicative of a status of each of the rechargeable cells; determine that a particular rechargeable cell is likely in a failure condition; identify a group of rechargeable cells that is in within one hop of the rechargeable cell that is likely in the failure condition; couple the group of rechargeable cells to a discharging system without coupling the rechargeable cell in the failure condition to the discharging system; and discharge the group of rechargeable cells to a target SOC.

Abstract: The application relates to an apparatus (100) for fatigue testing a wind turbine blade, and to a system and method using such an apparatus (100). The apparatus (100) comprises a base (110) for supporting a first end (12) of the wind turbine blade (10), and an edgewise actuator assembly (120). The edgewise actuator assembly (120) includes a ground-supported edgewise actuator (130) and a flexible cable assembly (140) for connecting the edgewise actuator (130) to the blade (10). The edgewise actuator (130) and the flexible cable assembly (140) are adapted to cyclically deflect the blade (10) relative to the base in the edgewise direction by repeatedly pulling the blade (10) in a substantially horizontal direction.

Abstract: A vehicle disabling apparatus for remotely disabling a vehicle having an engine comprises a source (4) of high frequency energy for generating a high frequency signal and a modulator (1) for modulating the high frequency signal by applying an effects signals package. The effects signal package comprises a plurality of respective effects signals and each effects signal comprises a pulse train, the effects signals package being non-vehicle specific. An antenna (6) directs the effects signal package modulated signal at a remote vehicle to disrupt the vehicle engine by affecting the target vehicle engine management system.

Abstract: A wind turbine blade tester includes a pair of linearly reciprocable actuators, such as hydraulic actuators. Each of the actuators is arranged to deliver a stroke to a wind turbine blade being tested. The stroke delivered by each of the actuators provides a controlled force in both the edgewise and flapwise directions. A method for testing a wind turbine blade is also disclosed.

Abstract: A test rig for testing blades for a wind turbine includes a fixing structure where a root end of a wind turbine blade can be fixed, a loading mass structure extending from the fixing structure, and an actuation structure which can apply a sinusoidal force to the loading mass structure so that a counterbalanced resonance is established between the loading mass structure and a blade which is fixed in the fixing structure. Due to the counterbalanced resonance, the force from the test rig onto the floor or other building components can be reduced relative to that known from the traditional rigs for blade testing.

Abstract: The invention provides a fatigue exciter for wind turbine blades. Wind turbine blades require excitation at or near their natural frequency to induce bending moments that simulate in service loadings and must be easily controllable and with the minimum of unnecessary added mass or force. The invention provides a device and a method by which force controlled feedback is used for finding an optimal excitation frequency. This force could be provided e.g. by a digital signal generator.

Abstract: A method for monitoring the operation of underwater-located equipment is provided. The method comprises: providing a sensor, the sensor comprising at least one of an acoustic sensor and an accelerometer, locating the sensor proximate the equipment to enable detection by the sensor of acoustic and/or acceleration components produced by the operation of the equipment, and producing electrical output signals in dependence on the detected components.

Abstract: A system for controlling production shut down of an underwater fluid production well, the well having a sensor for producing an output signal indicative of the state of the well and a valve which is actuable to shut down production activity of the well, comprises means for receiving the output signal; and a processor for processing the received signal to determine if a shut down is required and outputting a shut down signal to the valve; wherein the receiving means and processor are located at the well.
