The present application is directed to a hinge for a clamshell-type wireless communication device or other electronic device. In one embodiment, the communication device includes a base portion and a flip portion. A hinge mechanism movably couples the flip portion to the base portion so that the flip portion may pivot between a closed position and an open position. The hinge mechanism comprises first and second hinge parts, an indexing pin, and a spring. The indexing pin is rotatable relative to the first hinge part about a pivot axis. Additionally, the indexing pin is movable axially along the pivot axis. The second hinge part is non-rotatably engaged with the indexing pin and is rotatable about the pivot axis relative to the first hinge part between closed and open positions. The spring applies both an axial force and a rotational force to the indexing pin. The axial force biases the indexing pin into contact with the first hinge part, and the rotational force rotates the indexing pin to move the second hinge part from the closed to the open position.

A loading and unloading apparatus adapted for use on a wheel-supported trailer body is provided. The loading and unloading apparatus comprises a plurality of elongate support arms, a plurality of channels under the floor structure of the trailer body allowing the support arms to be mounted thereon and move longitudinally between a stored position and an operating position, at least one deck panel having two opposite end edge portions and means for securing the opposite end edge portions to the support arms. The opposite end edge portions are detachably mounted on the support arms.

Apparatus for reducing the sound pressure level (SPL) heard by a user of a mobile terminal, such as a cellular phone, when listening with an ear sealed to the mobile terminal and for providing adequate sound when the ear is not sealed to the mobile terminal. Some sound is laterally ported away from the ear-sealing region on the terminal such that the SPL heard with a sealed ear may be controlled to be within regulatory requirements. The need for mechanical or proximity switches may be reduced or eliminated. Adequate SPLs are provided when the ear is not sealed to the device by the combined use of distal and central ports. Excessive SPLs may be prevented for sounds such as alert signals.

A clip is provided for releasably securing an article of personal use, the article having a stud with a head spaced from the article. The clip includes a base connectable to a strap and a spring member biased against the base. The base includes a recess hole adapted to receive the stud head. The spring member includes a slot therein extending to an end substantially aligned with the recess hole, with the aligned end of the slot having a first width less than a diameter of the stud head.
摘要:
A docking and electrical interface for physically supporting and electrically interconnecting a personal communication device, such as a mobile cellular telephone, and a master electronic system, such as the electronic system of an automobile. Utilizing the interface allows an operator to selectively control the personal communication device using the master controls for the master electronic system, removing the need to access and manipulate the controls of the personal communication device.
摘要:
A self-releasing or break-away coupler that releases in response to experiencing a predetermined load. The self-releasing coupler includes a pair of jaws that form a fastener. Surrounding the jaws is a sleeve housing that deforms in response to the predetermined load when applied to the jaws. That is, as the housing deforms, the jaws are allowed to open so as to release a fastener or connector secured within the jaws.
摘要:
A system connector for an electronic device such as a cellular phone is integrally molded with a mic cavity for receiving a device microphone. By incorporating the microphone into the system connector, overall device thickness can be reduced, providing a more efficient use of space than the previous use of separate connectors.

Normal high load operation automatically varies nozzle area to maintain an optimum engine pressure ratio (EPR). An error signal representing fan damage is established by comparing the actual EPR to the predicted EPR. Compressor stalls are also monitored. In response to these signals a minimum nozzle area is set and modified. Automatic operation to hold EPR and afterburning is inhibited. Further signals representing satisfactory operation may reset the inhibiting action.
