A communication device having a theft deterrence feature includes a selective call receiver ( ), a transmitter ( ), a memory ( ) coupled to the selective call receiver and containing an encryption key ( ) and an address ( ), a secure memory ( ) coupled to the selective call receiver containing secure data that is accessible with the encryption key and further containing a stealth code, a tampering detection circuit ( ) for detection of unauthorized use by an unauthorized user of the communication device or another electronic device coupled to the selective call device, and a processor ( ). When the processor detects unauthorized use, it is to delete the encryption key, transmit a stealth code to a base station transparent to the unauthorized user when unauthorized use is detected, and receive data into the secure memory location transparent to an unauthorized user of the communication device.

A housing assembly includes a printed circuit board (PCB) (104), at least one electrical component (106) mounted on at least one side of the PCB (104) and electrically coupled thereto, a frame (102, 108) surrounding selected portions of the PCB (104), and a heat shrinkable composite laminate (110) having an inner conductive surface (115) and a non-conductive outer surface (140). The laminate (110) forms an enclosure supported by the frame (102, 108) about the PCB (104) and the at least one electrical component (106). The laminate outer surface (140) can be conductively coated and a contact (109) fixed to the PCB (104) can be used for electrically coupling to the inner conductive surface (115). The laminate (110) can include orifices (111,130) for a connector (107) and an antenna (113). In other embodiments (FIGS. 9, 10) a heat shrinkable composite laminate (120) can be electrically joined to a metal shell of a component (106) which is grounded through a pin (118) or the laminate outer surface (144) can be grounded to a metal cover.

A strain relief device (10) for wires is formed of a nonconductive plate (12) having a central axis (18) and a plurality of through-holes (14) distributed around the central axis (18). Each through-hole has a diameter selected to permit a wire to pass through it without binding. The non-conductive plate (12) includes a plurality of shoulders (20), one shoulder associated with each through-hole (14) and located between its associated through-hole and the outer perimeter of the plate (12). A preferred method of using the strain relief device is also described.
