An automatic keypad lockout system automatically disables the keypad or other buttons of a personal electronic device () when it is stored in an accessory () and then automatically re-enables the keypad upon removal of the device from the accessory without effort by the user. Encoding and decoding is accomplished through a variety of devices including magnetic (), electrical (), optical (), and mechanical () implementations. The automatic keypad lockout system is extendable (), (), (), and () to provide a unique identity (ID), to interchangeable accessories (). The unique ID is associated with a predetermined user configuration with which to configure the communication device (, and).

A mounting apparatus (,) suitable for retaining an antenna (,) includes a base (,) having magnetic sources (,) and (,) capable of providing varying magnetic forces. Magnet (,) retains the base against a metal surface (,), while an electronically controlled magnet (,) provides additional retention of the base (,) against the metal surface (,) when activated, thereby preventing movement of the base and antenna (,).

Portable radio housing

A radio housing (101) includes first and second retention mechanisms (216, 218) on both its back and bottom surfaces (104, 106) for selectively retaining a variety of battery form factors and providing a variety of radio configurations.

Adaptable portable radio

A speaker assembly (100) includes a speaker (202) having at least one speaker terminal (206) and a magnet (204) which generates a magnetic field. The speaker assembly (100) also includes a circuit board (116) having at least one terminal (110). A metal member (106) is coupled to the circuit board (116) and is used to magnetically attach speaker (202) to circuit board (116). Upon speaker (202) being magnetically coupled to circuit board (116), the at least one speaker contact (206) becomes coupled to speaker terminal (110). Thereby, allowing for a quick way of attaching and detaching speaker (202) to and from circuit board (116).

A process for fabricating an electromagnetic shield for a display provides for a sheet upon which a metal mesh pattern and a border surrounding the metal mesh pattern is photo-chemically etched on the sheet. In addition, a portable radio having an electromagnetic shielded display provides for a bordered metal mesh disposed between a cover and a display.

A mechanical rotational control assembly (100) is provided having a knob (20) engaged to a potentiometer's rotating shaft (55). A friction element (40), such as a washer made of a material having similar temperature characteristics to the knob (20), is interlocked to the stationary portion (57) of the potentiometer. The peripheral boundary (47) of the friction element (40) is engaged to the skirt portion (25) of the knob (20), so as to produce a fricional force when the knob (20) is rotated, and thereby increasing the rotational torque of the rotational control assembly.
