Abstract: An electric power generation controller for use in an aircraft to control an electric power generating apparatus including a manual transmission which changes speed of rotational power of an aircraft engine, transmits the rotational power to an electric power generator, and includes a plurality of gear stages. The electric power generation controller includes: a rotational frequency receiving section configured to receive an input rotational frequency or an output rotational frequency of the manual transmission as a monitoring rotational frequency; and a manual transmission control section configured to, when the monitoring rotational frequency exceeds a first threshold, output a shift-down signal to perform shift-down from an upper stage to a lower stage, and when the monitoring rotational frequency falls below a second threshold, output a shift-up signal to perform shift-up from the lower stage to the upper stage, the first threshold being set to a value larger than the second threshold.

Abstract: An electric driven hydraulic fracking system is disclosed. A pump configuration that includes the single VFD, the single shaft electric motor, and the single hydraulic pump that is mounted on the single pump trailer. A power distribution trailer distributes the electric power generated by the power generation system at the power generation voltage level to the single VFD and converts the electric power at a power generation voltage level to a VFD voltage level and controls the operation of the single shaft electric motor and the single hydraulic pump. The power distribution trailer converts the electric power generated by the power generation system at the power generation level to an auxiliary voltage level that is less than the power generation voltage level. The power distribution trailer distributes the electric power at the auxiliary voltage level to the single VFD that controls an operation of the of the auxiliary systems.

Abstract: An electric driven hydraulic fracking system is disclosed. A pump configuration includes the single VFD, the single shaft electric motor, and the single hydraulic pump mounted on the single pump trailer. A controller associated with the single VFD and is mounted on the single pump trailer. The controller monitors operation parameters associated with an operation of the electric driven hydraulic fracking system as each component of the electric driven hydraulic fracking system operates to determine whether the operation parameters deviate beyond a corresponding operation parameter threshold. Each of the operation parameters provides an indicator as to an operation status of a corresponding component of the electric driven hydraulic fracking system. The controller initiates corrected actions when each operation parameter deviates beyond the corresponding operation threshold. Initiating the corrected actions when each operation parameter deviates beyond the corresponding operation threshold maintains the operation of the electric driven hydraulic fracking system.

Abstract: Described is an oscillating device for generating electricity from a fluid flow, comprising at least one oscillating part, at least one support, fixed to a reference surface and connected to the oscillating part at an oscillation axis, at least one counter-balancing system connected to, and/or acting on the oscillating part, at least one adjustable profile configured to be at least partially immersed in the fluid flow and movably connected to the oscillating part. The oscillating device comprises an adjustment system configured to change the position of the adjustable profile with respect to the fluid flow between at least one position of greatest resistance and at least one position of least resistance. The invention also relates to an adjustment method for oscillating devices designed to generate electricity, according to which adjustments to the position of the adjustable profile are made as a function of certain parameters, such as the speed and/or the change in direction of the oscillation of the oscillating part, detected by a series of sensors.

Abstract: An electric driven hydraulic fracking system is disclosed. A pump configuration that includes the single VFD, the single shaft electric motor, and the single hydraulic pump that is mounted on the single pump trailer. A pump configuration includes a single VFD configuration, the single shaft electric motor, and the single shaft hydraulic pump mounted on the single pump trailer. The single VFD configuration converts the electric power at the power generation voltage level distributed from the power distribution trailer to a VFD voltage level and drives the single shaft electric motor to control the operation of the single shaft electric motor and the single hydraulic pump. The VFD voltage level is a voltage level that is required to drive the single shaft electric motor. The VFD configuration also controls operation of the auxiliary systems based on the electric power at the auxiliary voltage level.

Abstract: Methods and apparatus for regulating the function of a suspension system are disclosed herein. Suspension characteristics often contribute to the efficiency of a suspended system. Depending on the desired operating parameters of the suspended system, it may be desirable to alter the functional characteristics of the suspension from time to time in order to maintain or increase efficiency. The suspension hereof may be selectively locked into a substantially rigid configuration, and the damping fluid may be phase separated and/or cooled to increase damping rate during use (or offset rate degradation). The suspension hereof may generate power usable to achieve any or all of the foregoing or to be stored for use elsewhere in the suspended system or beyond.

Abstract: A safety system for engine powered machinery having a fuel cut functionality to promote more rapid shutdown of the rotating parts of the engine powered machinery. In one aspect, the system is implemented as a wiring harness disposed exclusively on the engine which simultaneously disables one or more ignition coils and prevents a fuel-air mixer from supplying a mixture of air and fuel to the engine upon activation of a safety switch. In alternate aspects, the system further comprises a stator brake which is activated by the safety switch to provide additional braking torque on the engine. These features bring the machinery to a rapid halt, further enhancing safety.
