Abstract: An acoustic transducer comprises one or more electromagnetic motors that drive one or more sets of multiple diaphragms to provide acoustically efficient loudspeaker systems having dimensions that allow use in applications that would be difficult or impossible with traditional transducers. The diaphragms may be driven directly, inertially or fluidically. If diaphragms are driven by rods that pass through holes in the diaphragms, noise may be generated by air that leaks through the pass-through holes. This noise may be reduced or eliminated by measures that reduce or eliminate the air leakage.

Abstract: A shore power cord includes a power supply connector electrically connected to a vehicle connector. In some cases, the vehicle connector includes features to selectively secure the vehicle connector to a vehicle power receptacle inlet. In some cases, the shore power cord includes a test module that evaluates the condition of the cord set and a power supply when the cord set is connected to the power supply.

Abstract: An enclosure for storing more than one electronic device. The enclosure includes a frame having a rear surface to be in apposition to a support surface, a rack supported within the frame, the racking having at least one slot for receiving an electronic device, and a door supported by the frame and pivotable about a generally vertical axis between a closed position substantially perpendicular to the rear surface and an open position substantially planar with the rear surface, the slot being accessible through a side of the enclosure when the door is in the open position.

Abstract: A method is provided for controlling a dynamic range of audio reproduction in an interior of a vehicle. An input audio signal is received by an audio processor. The input audio signal is split into a first and a second processing path. The input audio signal of the second processing path is compressed. A noise-related parameter of the vehicle is characterized. A gain control is applied to the compressed audio signal of the second processing path in response to the noise-related parameter. The compressed and uncompressed audio signals are synchronously recombined. The combined audio signal is reproduced to the interior of the vehicle.

Abstract: A cart with one or more of a power supply system that includes an outlet box and a plurality of flexible receptacles, a bi-layer shelf, a positionable cable routing tray, and a removable cable management module.

Abstract: A tablet storage device includes a frame having a plurality of slots, at least one of which is adapted to hold a tablet. A docking station can be disposed in at least one slot. In some cases the docking station is configured to align a tablet as the tablet is positioned in the slot such that a corresponding port in the tablet aligns with, and connects to, a connector. The frame also has a surface to attach the device to a vertical surface and can have a door that can be moved from an open to a closed position and adapted to retain at least one tablet held within at least one slot when the door is closed. A power supply system and/or a network connection system can be provided with the tablet storage device.

Abstract: A tablet storage device includes a module on a cart frame that includes a wheeled base. A cart module defines a selectively accessible interior space having multiple storage slots within the interior space for holding tablets. In some cases a tablet storage device holds multiple tablets using two or more modules in a stacked arrangement on a wheeled base. Each module can hold a portion of the multiple tablets within storage slots within an interior space inside the module. The storage slots may have connectors for connecting to tablets, and the cart frame can have a network connection system that is adapted to provide a network connection for each tablet that is connected to one of the connectors. The cart frame may also have a power supply system for charging each tablet that is connected to one of the connectors.

Abstract: Some embodiments provide a pivot mechanism and/or system that includes a support member defining a cavity and an extension member at least partially located within the cavity. In some cases one or more inner surfaces of the cavity can provide one or more pivots defining multiple pivot axes about which the extension member is generally pivotable through corresponding pivot ranges. The extent of the pivot ranges can be defined by the cavity within the support member. In some cases cooperating clamp members engage the extension member and the support member to retain the extension member within the cavity. The clamp members may also include sliding surfaces that slidingly engage with the support member to provide frictional resistance to pivoting movement of the extension member. Electronic display pivoting and positioning systems are also provided as are methods for positioning and pivoting electronic displays.

Abstract: An ergonomic task chair having a front and a rear, including a laterally extending seat having a front and a rear, a back brace disposed above the rear of the seat, and a knee support disposed in the front of the chair, wherein the back brace and the knee support have a first position where there is a first minimum distance between the back brace and the knee support and a second position where there is a second minimum distance between the back brace and the knee support, the second minimum distance being less than the first minimum distance, wherein movement from the first minimum distance to the second minimum distance is triggered by a downward movement of the seat.

Abstract: A cable clasp comprises a tail including an engagement face. The cable clasp further comprises a head including a handle that connects to the tail and defines a mouth opening into which the tail is movable. The cable clasp is biased towards a closed-loop position in which at least a portion of the tail is disposed in the mouth opening. The head further includes a lock having a catch engageable with the engagement face in a lock position to: 1) prevent motion of the tail relative to the head in a first direction, and 2) permit motion of the tail relative to the head in a second direction opposite the first direction by sliding the catch over the engagement face. The catch and the engagement face are also disengageable in a release position to permit motion of the tail relative to the head in both the first and second directions.

Abstract: The present invention is a device for use in cleaning a fabric surface of dust, dirt, pet hair and other debris present on the surface. The device includes a housing coupled to a base. The base is coupled to at least one movable cleaning member configured to engage a surface for picking up debris from the surface. The debris is deposited into a debris collection chamber by way of interaction with another portion of the device. The debris collection chamber is selectively emptiable by an operator thereof so that the device may be subsequently reused.
