Abstract:
A speaker assembly which includes a first diaphragm, a second diaphragm and a driver operationally positioned in an enclosure formed by the first diaphragm and the second diaphragm. The second diaphragm is made of a material composition which allows it to block sound energy, and reflect sound energy along to the first diaphragm.
Abstract:
A flat panel speaker system is provided. The system includes, a modified panel having a front surface and a rear surface, wherein the modified panel acts as a diaphragm for the flat panel speaker system; a supporting member coupled to the rear surface of the modified panel; and a detachable driver operationally coupled to the supporting member.
Abstract:
A high fidelity sound system for a mobile platform is provided. The system includes a plurality of panels forming interior surfaces of a passenger cabin of the mobile platform. The system additionally includes a plurality of exciters. Various selected panels have at least one exciter is affixed thereto, wherein the exciters are adapted to resonate the panels to thereby generate sound waves. The system further includes a processing center that controls signals that drive the exciters. The signals are modified by the processing center so that each exciter generates sound waves within a specific frequency bandwidth that is based on the panel material or structure to which each exciter is affixed.
Abstract:
An overhead stowage system for holding luggage above a passenger seat of an airplane has a holding bin movably coupled to a support structure of a modular design which may be preassembled prior assembly with the airplane. A motor drives a cable chain which is attached to the holding bin for moving the holding bin with respect to the structure. The motor is operatively coupled to a horizontal shaft which has a length corresponding to the length of the overhead stowage bin and which has an drive sprocket driving the cable chain as it is driven by the motor. A pulley disposed on the support structure redirects the force of the cable chain, as driven by the motor, for lifting the holding bin relative the support structure. The motor provides all or a partial force for lifting the holding bin. Switches and sensors located on the support structure and holding bin operate in accordance with the position of the holding bin relative the support structure for determining when and how the motor is to operate.
Abstract:
A vehicle seat for supporting a passenger of a vehicle. The seat includes a seat frame having a mount for mounting the frame to the vehicle, a support extending from the mount, a seat bottom mounted on the support for supporting the passenger when occupying the seat, and a seat back extending upward from the seat bottom. The seat back has a front surface oriented to face the passenger occupying the seat and a rear surface opposite the front surface. A video monitor is mounted on the seat frame, and a digital processor is operatively connected to the video monitor for processing a digital input for display as an image on the video monitor.
Abstract:
A method and apparatus for assisting movement of a bin into a closed position. An assistance system associated with the bin may be activated in response to a manipulation of a switch associated with the bin. The assistance system may comprise a biasing system and a switch. The biasing system may be configured to generate a force in a direction towards a closed position for the bin. A switch may be connected to the biasing system and configured to activate the biasing system when a selected amount of weight is present in the bin. The force in the direction towards the closed position for the bin may be generated in response to activating the assistance system.
Abstract:
A system for attaching a wall panel includes a wall panel and a lock strip. The wall panel has a back and a tab extending from the back. The lock strip is moveably attached to a wall frame member, and has a three-position locking slot, including a receiving portion configured to receive the tab, a locking portion configured to lock the tab with respect to the frame member, and a release portion configured to release the tab. The wall panel is removably attachable to the frame member by inserting the tab into the receiving portion and linearly moving the lock strip to lock the tab in the locking portion. The system can be used for attaching interior sidewall panels in an aircraft.
Abstract:
A compartment for a transportation device is provided. The compartment may include a one-piece basin, an inflatable wall member, and multi-directional support arms to attach the basin within the transportation device. The one-piece basin may fit through an opening in the transportation device. Methods of installation for installing the compartment within the transportation device are also provided.
Abstract:
An apparatus for providing both a visual message and audio information simultaneously. The apparatus includes a display sign including an image or indicia thereon which provides visual information to an individual or a group of individuals being addressed by a user. The apparatus further includes a loud speaker and a lightweight, miniature microphone which is worn or carried by the user. The microphone provides an input signal to a microphone and amplifier module which drives the loud speaker. An optional volume control allows the volume of the audio signal generated by the loud speaker to be adjusted by the user. The apparatus forms a lightweight, easy to carry and convenient means for allowing a user to provide both visual and audio information simultaneously. The apparatus can easily be held with one or both hands of the user.
