The signal processing device comprises a multi-band dynamic range controller, wherein the multi-band dynamic range controller receives an audio signal and includes a first band splitting unit and a resonant band adjustment unit; the first band splitting unit is configured to split the audio signal into multiple bands and obtain at least one resonant band therefrom, which has a resonant frequency band signal in a resonant frequency range of the audio signal; and the resonant band adjustment unit is configured to adjust the resonant frequency band signal based at least on a resonant band dynamic range control gain and output an adjusted resonant frequency band signal for combination with other band signals into a compression output signal.

Abstract: The present invention discloses an earphone. The earphone comprises: an earbud, wherein a cable comes out from an open end of a stem of the earbud; and a strain relief element mounted at the open end, the material of which is softer than that of the stem. The strain relief element contains a cable tube where the cable passes through and the inner wall of the cable tube fits the cable in a close manner. According to an embodiment of this invention, the present invention can provide a better strain relief effect.

Abstract: An aircraft spring assembly having a spring, an end fitting including a spring engagement formation arranged to be mechanically coupled to an end region of the spring and a coupling formation for coupling the spring assembly to an aircraft anchor point. The coupling formation includes a load bearing surface via which loads from the anchor point can be transmitted into the spring assembly. The assembly further includes an integral damping member provided within the load path between the load bearing surface of the coupling formation and the end region of the spring.

Abstract: A method of preloading an aircraft assembly involving a step of operating an extendible preloading tool to move a landing gear strut to decrease the distance between first and second link attachment joints for attachment of a preloading linkage. A tool and aircraft assembly are also provided.

Abstract: A landing gear assembly having a first part movable relative to a second part, and a spring coupled to the first and second parts via first and second anchor points. A lost motion assembly is provided to enable one of the anchor points to translate along one of the parts. As such, the spring extends less as the first part moves relative to the second part than it would if each anchor point was fixed to a respective part.

Abstract: A landing gear assembly 10 having first and second parts 12b, 14b movably mounted with respect to one another. The landing gear assembly includes a critical space 32. A spring assembly 26 is arranged to bias the first and second parts to move relative to one another. A spring support 30 is provided to inhibit a broken portion of the spring assembly entering or contacting the critical space following a spring failure.

Abstract: A composite cable is provided with a primary strength member comprising wire lay synthetic fibers coaxially wound around a cable core and an outer jacket of wire lay steel wires coaxially wound over the primary strength member. The composite cable provides improved bend-over-sheave performance, and is configured to be suitable for used as a purchase cable in an aircraft arrestment system.

Abstract: A device for transmitting a load from an object to a load-bearing element is provided. The device includes an attachment mechanism for attaching to a load-bearing element, such as a vertical stanchion. A loading mechanism includes a pressure block and a mechanism interconnecting the pressure block and the attachment mechanism. The loading mechanism can apply a preload to an object and transmit a force from the object to the load-bearing element.

Abstract: A foundation adapter module includes a plate assembly having a fitting attachable to a piece of equipment to attach the equipment to a track system. An upper plate is adjustably fastenable to a lower plate for locating the fitting in any location between tracks of the track system and between tie-down points along the tracks. A deck tile system includes arch deck tiles fastenable to the track system. A further deck tile system includes flat deck tiles fastenable to a raised frame attached to the track system.

Abstract: A retractable retention device for use to stow away an equipment tether or leash that is used to satisfy sports equipment, such as snowboarding and snow skating, safety regulations.

Abstract: A tiedown system foundation adapter system provides greater flexibility in spotting equipment on a support surface. An adapter module includes a plate assembly that drops into a slotted track system and is slid along the track system until it fits into an attachment point that restrains the plate assembly from vertical pullout and motion transverse to the track. The plate assembly is then locked into position to restrain it from further translation along the track. An equipment fitting is translatably mounted with respect to the upper surface and attaches to a complementary attachment fitting on the bottom of a piece of equipment. By locating a number of modules in desired locations along the tracks and locating the equipment fitting in each module, a piece of equipment can be oriented in virtually any position and location in the space to be furnished. A deck system for a flush floor is also provided.

Abstract: A joiner panel system is formed from a composite material and includes a panel attached to a deck by a coaming or shoe and attached at its upper edge by a curtain plate that fits around obstructions at the ceiling area. The shoe can be readily installed to an uneven steel deck by stud welding to reduce installation time or attached to a composite material deck. A curtain plate fabrication method uses a laser scan or close range photogrammetry of the overhead area to optimize and automate the cutting of curtain plate sections. The curtain plate sections can then be readily installed in the overhead area. A composite material panel to provide good flame, smoke and toxicity properties and good mechanical properties is formed from a phenolic resin foam material, micro-balloons to reduce the weight and density, and reinforcing fibers and powder material to improve the mechanical properties. The panel can be formed by a method in which the core and face skins are co-cured to provide a good bond.
