Abstract: A method of operating a fastener driver comprises initiating a fastener driving operation by moving a driver blade from a retracted position toward a driven position, and detecting that the driver blade has become jammed in an intermediate position between the retracted position and the driven position. The method further includes moving a latch from a locked position, in which a lifter assembly is maintained in an engaged position by the latch for moving the driver blade from the driven position toward the retracted position, to a released position, in which the lifter assembly is movable away from the driver blade. The method further includes driving a motor to rotate a lifter of the lifting assembly, thereby moving the lifter assembly away from the driver blade, then, returning the lifter assembly to the engaged position, and moving the latch from the released position to the locked position.

Abstract: A fastener driver comprises a driver blade movable from a retracted position to a driven position and a lifter assembly for moving the driver blade from the driven position toward the retracted position. The fastener driver also includes a first sensor to detect the driver blade in the driven position, a latch which, in a locked position, maintains the lifter assembly in an engaged position, an actuator coupled to the latch for moving the latch between the locked position and a released position, in which the lifter assembly may move away from the driver blade, and a controller electrically connected with the first sensor and the actuator. In response to an absence of a signal from the first sensor after a predetermined time following initiation of a fastener driving operation, the controller triggers the actuator to move the latch from the locked position to the released position.

Abstract: An aft pivot assembly can include a mount device securable to an aft portion of a payload of an aircraft for facilitating release of the payload. The aft pivot assembly can include a shaft operable with the mount device and a release component, the shaft being rotatable about multiple shaft axes relative to the mount device so as to either minimize or eliminate carriage loads about the aft portion, while reacting jettison loads during a jettison event or phase. The rotation of the shaft about its shaft axes can further be limited via a limit device. As the payload transitions from a carriage phase to a jettison phase, the shaft moves in multiple degrees of freedom and in multiple axes relative to the mount device.

Abstract: Sludge from an anaerobic digester is treated to recover one or more of fibers, or solids or liquids with a high nutrient content. The solids or liquids can be used as a fertilizer. The fibers can be used in a plant growing medium. Solids are separated from liquids in the sludge and dried. The solids may be dried to produce a flake or pellet. Ammonia in the liquids is recovered and used to produce a concentrated acidic ammonium salt solution. This solution may be mixed with the solids to produce a nitrogen enhanced solid. The fibers and solids or liquids can also be used in combination to produce an enhanced plant growing medium. A device and process for removing ammonia from a liquid can be used in the system or separately.
