A drop-in adjustable trigger assembly has a camming safety linkage to selectively move and engage a bolt sear to positively prevent movement of the bolt sear. The drop-in trigger assembly housing carries a pivoting bolt sear engagement member which is connected to a sear safety linkage. The housing has a sear safety linkage slot defined therein which guides the pivoting sear safety linkage in response to actuation of an upwardly projecting thumb safety lever's actuation. A trigger bracket preferably carries a removable, reversible trigger shoe and is configured to pivot within the housing about a pivot point within the housing, and the trigger bracket carries an adjustable rocker having (preferably) a first stage movement adjustment and a second stage length adjustment. The pivoting safety mechanism's safety linkage pivots rearwardly to push upon or cam the bolt sear upwardly, thus disengaging the bolt sear from the trigger sear.

The present invention relates to a load and moment sensor for a prosthetic device detecting load in a single direction and moment in a single plane. The load and moment sensor includes a sensing element, and a plurality of strain gauges placed in specific locations of the sensing element. The plurality of strain gauges is part of a plurality of resistor circuits such as Wheatstone bridges. While the strain gauges can be located on a single sensing element, some resistive elements of the Wheatstone bridges can be located elsewhere on the prosthetic device. The combination of the location of the strain gauges and the use of the Wheatstone bridges allows for good side load rejection which is load and moment not in the single direction or the single plane.

A remote operated vehicle system comprises a topside, a fish equipped with a GPS receiver, a transmitter for transmitting GPS position data, and a receiver operable to receive the transmitted position data. Transmission may be from the fish to the topside or from the topside to the fish. Alternatively, a second transmitter and receiver give two-way transmission. These arrangements allow the position of the fish to be monitored or tracked, so that it can be readily rescued in the event of damage or breakdown. Alternatively, predetermined position data can be sent to the fish, allowing it to automatically navigate a desired route. Particular embodiments include an umbilical cable for connecting the fish and the topside together and operable to carry signals, including position data, between the two, an additional GPS receiver on the topside so that the fish can navigate to the topside unaided, and a buoyancy control device which brings the fish to the surface.

The invention relates to a wind turbine blade with devices for modifying the aerodynamic surface or shape of the blade. The position and movement of these devices are controlled by a pneumatic actuator powered by pressure from a pressure chamber connected to the actuator via a valve system controlling the powering. The valve system in return is operated by a control unit conveying control signalsto the valve system via a signal communication pathway. The communication pathway may comprise a power link or pressure tubes with a liquid or a gas. In one embodiment the gas used is of a lower molecular weight than 28.9 kg/kmol and thereby lower than air, whereby the speed of the pressure signals being sent from the control unit is increased and thereby the operational speed of the aerodynamic devices. The invention further relates to a wind turbine comprising a tower, a nacelle mounted to one end of the tower, and a rotor with at least one wind turbine blade according to the above.
