A transmission playback device for selectively storing discrete transmission data is configured for use with a telecommunications accessory device. The playback device includes a memory assembly having a pair of identical storage buffers. A first storage buffer has memory designated for continuously recording transmission data, and a second storage buffer has memory designated for selectively storing a discrete message from the transmission data. A controller exchanges the designations of each storage buffer upon a request by a user such that the second storage buffer becomes designated for continuously recording transmission data and the first storage buffer becomes designated for selectively storing a discrete message from the transmission data.

The cellular telephone of the present invention includes a generally sealed, moisture resistant electrical external connector that resides in the wall of the phone housing and provides a series of electrically conductive pathways which lead from the external surface of the housing, through the housing wall, to designated areas on an internally located printed circuit board. More particularly, these electrically conductive pathways or contacts, that essentially penetrate the cellular telephone housing, are incorporated within the housing wall via an insert molding, press fitting, or similar process such that a generally sealed, moisture resistant barrier is formed between the individual contacts which comprise the connector and the surrounding housing.

Radiotelephone flip covers hinged to a radiotelephone housing include a secondary keypad configured to overlie a primary keypad of a radiotelephone. A flip cover is movable between a closed position wherein at least a portion of a primary keypad is covered, and an open position wherein a primary keypad is uncovered. When a flip cover is in a closed position and when a secondary keypad key is depressed by a user, the depressed key in-turn depresses a respective primary keypad key to perform a radiotelephone function.

A wireless communications device, such as a cellular telephone, is provided with a torsional hinging mechanism for rotatably coupling a flip cover to the device's main body. The torsional hinging mechanism both minimizes lateral loading and causes the flip cover to automatically assume the open position when released. One, and preferably two, torsional axles interconnect the main body to the flip cover. One end of the torsional axle is engaged by the main body so as to prevent relative rotation therebetween, for example by fitting the end through a retaining slit in the main body. The opposite end of the torsional axle is engaged by the flip cover so as to prevent relative rotation therebetween, for example by fitting a keyed end into a keyed hole. When the flip cover is in the closed position, the torsional axle is rotationally loaded so as to urge the flip cover towards the open position. Optionally, the one or more of the torsional axles may include an acoustic passage for acoustically connecting the flip cover to a microphone in the main body when the flip cover is in the open position.

A telecommunication instrument having a microphone mounted in a flip arm is electrically interconnected to the transceiver portion of the instrument by a slip ring connection. The slip ring connection enables the flip arm to be rotated between stored and operating positions during use, and easily removed from the instrument for repair or replacement. The slip ring connection eliminates any need for extending wires or flexible circuits between the flip arm and the main body of the instrument.

A plurality of arms extend outwardly from an accessory structure and are adapted to engage slots in a base structure to which the accessory structure is to be mounted. The arms are normally biased to a position at which they are freely insertable an removable from the slots in the base structure, and movable to a position at which the arms are locked in the slots in response to forcedly maintaining the arms at a spaced apart distance greater than the distance of which the arms are disposed in the normally biased position. The arms are returned to their normally biased position in response to depressing an actuator mounted in the accessory structure, and moved to the spaced apart locking position in response to releasing the actuator. The problems of fatigue failure, wear, breakage and decrease of positive retention between accessory and base structures using current releasable locking mechanisms is overcome.

An improved antenna mounting is designed to quickly release an antenna or antenna lead from a portable radio cabinet. The mounting assembly releasably locks the antenna in place by a spring loaded quick release mechanism in both the axial and radial dimensions.
