Abstract: This microphone includes a microphone element, speaker and antenna all internal to the microphone housing. These components are carried by a chassis that is fastened to the microphone body at its lower end which also provides the effective attachment point for the microphone cable. The speaker is mounted in the chassis at an angle having its face slight upwardly incline to project sound towards the top of the microphone. An antenna element includes walls on either side of the speaker for reflecting sound upwardly. The antenna element has apertures in its top portion to allow for the passage of sound therethrough. The microphone element is also in a position for picking up sound through the top of the microphone.

Abstract: A whip antenna assembly of conductive cable, conductive base section, conductive protection knob and a environmental cover. The conductive antenna cable is constructed of multiple layers of brass plated stainless steel wire wound in a helix about a single wire strand which serves as a central core. The conductive base section and conductive protection knob consist of a zinc alloy and are injection cast onto opposite ends of the conductive antenna cable. An environmental cover made from polyurethane is injection molded over the subassembly of conductive antenna cable, conductive base section and conductive protection knob.

Abstract: Apparatus having an integral coaxial antenna coupled via a coaxial connector to its internal circuitry has a coaxial switch/connector for alternatively coupling an external coaxial signal source to the internal circuitry, thus reducing impedance mismatch to a minimum with no impedance matching network required.

Abstract: A completely flexible dipole antenna is formed from coaxial cable having a braided wire core with skirt also formed of shielding over a flexible sleeve. A coil spring which is not electrically active supports the antenna above the connector. A non-wearing female connector utilizes a flexible conductive elastomer contact contained within an insulating body.

Abstract: A console for charging a portable communications device and converting it for mobile operation can accommodate portable units of varying lengths. The contacts for the charging current are positioned by the insertion of a portable unit by means of a unique reel mechanism. Interconnection and latching are also activated by the insertion of the portable unit. The converter connector serves as a part of the latching and locking apparatus which makes the unattended portable essentially theft proof.

Abstract: An improved subminiature electrical connector arrangement especially suited for miniature electrical or electronic apparatus. The connector arrangement includes a two-piece female connector assembly wherein one part thereof may be suitably interconnected to the circuitry of the apparatus while the same is outside the associated housing. This connector may then be placed in alignment with an opening within the housing and a second connector portion inserts within the opening and makes a snap-fit, weather tight seal therein and engages said first connector portion, all without special tools or any additional hardware. An associated male connector plug makes a convenient interconnection with the female assembly by including a hook-like projection overhanging one edge thereof and which engages a recess in the top of a housing to permit the male plug to rotate downwardly and inwardly into correct mechanical and electrical engagement with the female connector assembly.

Abstract: A housing having key portions of a resilient pad extending therethrough with a metal impregnated elastomer pad overlying the rear surface thereof, a sheet of insulating material having openings therethrough corresponding with the key portions and a plurality of contact areas on a printed circuit board overlying the insulating sheet and having a plurality of contacts on the rear surface thereof, a connecting link formed of a second sheet of insulating material having a plurality of areas of metal impregnated elastomeric material extending therethrough and corresponding in position with the contacts, a second PC board having a plurality of contacts in contact with the elastomeric areas of the connecting link and a frame compressing all of the components together to provide an electrical contact to the elastomeric material in the connecting link and complete a circuit between various contacts on the two printed circuit boards and provide a weather-tight multi-push button switch.

Abstract: The connector system includes a radio mounted receptacle with an integral transfer switch, and a separate connector and cable for interface with external radio frequency (R.F.) circuits, and provides a method of connecting external R.F. circuits to a portable radio and for simultaneously and automatically transferring the internal radio circuits from an integral radio antenna to the receptacle. The integral transfer switch of the receptacle connector includes a movable conductive plunger retained within a conducting sleeve and adapted to slide in an insulator between a first position at which the head of the plunger engages an inturned end of the sleeve, and a second position in which the plunger engages a flexible contact connected to the radio circuit and moves it away from a contact connected to the selfcontained antenna.
