    Abstract: Disclosed are passive acoustic structures, portable audio devices configured for use with the passive acoustic structures and methods for enhancing the frequency output of a speaker of a portable device configured for use with a disclosed passive acoustic structure. The disclosed portable audio device may include an opening proximal a speaker cavity of the device, a shutter or door to open and close the opening so that the device interoperates with a docking station of a passive acoustic structure including a labyrinth or a transmission line system that may increase the frequency range of the system. For an end user to experience the music and multimedia features of a portable audio device, and in particular a mobile communication device, the above-described passive acoustic structure may provide a bass enhancement for the typically small loudspeaker of a portable audio device with no additional loudspeaker and therefore no additional circuitry.

    Abstract: A friction clutch (440) for use with a 360 degree dual pivot point hinge (106) permits rotation about but one pivot point axis (444 or 445) at a time to assure proper 180 degree operation of each hinge member (411, 413 and 412, 414) associated with the hinge (106), thereby eliminating the misalignment problems typically experienced by dual pivot point hinges.

    Abstract: A portable electronic device (200) including a housing having a movable housing portion in the form of a flip, rotating blade or slider portion. A controller is electrically coupled to a plurality of light shutter portions in the movable housing portion, wherein the controller independently configuring each light shutter portion between first and second light transmitting states based upon input from a sensor, an application or based upon the configuration of the housing. The shutter portions may obscure or reveal an underlying display or inputs.

    Abstract: A mounting system (10) and method for adjusting the position of a PCB (14) in a housing (22) therefor is provided. An annular, stepped mounting member (16) having axially and radially spaced surface portions (19) provides predetermined positions for the PCB (14) in the housing (22) based on the size of a mounting opening (20) of the PCB (14). The PCB (14) is placed onto the mounting member (16) with those surface portions (19) that are of smaller diameter than the opening (20) fitting therethrough until the first portion (19) having a larger diameter is encountered which will be engaged against the PCB (14). In this manner, the present system (10) allows for a relatively quick and easy change to the size of the PCB mounting hole opening (20) to be made to effect a change in the PCB vertical position in the housing (22) thereby avoiding expensive and time-consuming changes that are usually required when the position of the PCB (14) needs to be changed to accommodate component reconfigurations and the like.

    Abstract: An electronic device (100), suitable for operation in a compact configuration, a portrait configuration, and a landscape configuration includes a first housing (102) and a second housing (104) coupled to the first housing. A data coupler (502) electronically couples the first housing with the second housing, and a bar linkage slides the first housing and the second housing in a non-linear motion with respect to each other.

    Abstract: Un dispositivo (200) electrónico portátil que incluye un alojamiento que tiene una porción de alojamiento móvil en forma de una aleta, hoja rotativa o porción deslizable. Se acopla un controlador en forma eléctrica a una pluralidad de porciones obturadoras de luz en la porción de alojamiento móvil, donde el controlador configura en forma independiente cada porción obturadora de luz entre el primer y segundo estados de transmisión de luz basándose en la entrada de un sensor, una aplicación o basándose en la configuración del alojamiento. Las porciones obturadoras pueden oscurecer o revelar una pantalla subyacente o entradas.

    Abstract: A radio device such as a radio modem having a radio shielding receptacle (10) with a base (16) and first and second sides (40, 42) and having side walls (14). A first circuit board (e.g. radio frequency circuit board 20) is mounted in the receptacle between the side walls, extending across the first side of the base. A second circuit board (e.g. logic circuit board 22) is mounted across the second side of the base such that the base of the receptacle separates the first and second circuit boards. A radio shielding housing (top assembly cover 26and bottom cover 38) surrounds the receptacle and the first and second circuit boards. In an aspect of the invention the device is dimensioned to conform to a Personal Computer Memory Card International Association standard and has an antenna connection (76). An elongate recess (74) extends between the two sides of the housing and the antenna connection is mounted within the recess.
