Abstract: The present invention provides a power adapter (10) adapted to couple an external antenna (17) to a communication device (30) by way of a cable (12) which is typically plugged into a cigarette lighter of a vehicle or some other power source at one end, and an input connector of the communication device (30) at the other. In particular, the present invention provides a simple one-piece vehicle power adapter which also provides RF input/output capability for connection to an external vehicle antenna. According to certain aspects of the invention, the adapter can be configured to have a variety of selection mechanisms. For example, the communication device could include an RF switch (34) and control circuitry for selecting either the internal or external antenna for optimum reception. Alternatively, the cable could include an external switch (70) for allowing the user to select the desired antenna. Finally, the cable could include a component which automatically actuates the switch to select the external antenna when the external antenna is connected to the communication device.

Abstract: An electronic device coupling apparatus is used to couple two electronic devices through a hinge. A first electronic device (221) is disposed within the main housing of a radiotelephone (101). The second electronic device (301) is disposed within a movable element (103) of the radiotelephone (101). The coupling apparatus uses a piece of flex (215) which is torsionally twisted upon the opening of the movable element (103) of the radiotelephone (101). Additionally, the flex (215) is coupled to the electronic devices (221, 301) using an elastomeric connector (217).

Abstract: An electronic antenna switching system switches between an internal and an external antenna (105, 107) on a portable radiotelephone (103). Here, the external antenna (107) contains a coil cord connector (111). In the coil cord connector (111) an electrical ground or a predetermined voltage is applied to a center conductor (205) of a coax cable (201). Internal to the radiotelephone (103), an antenna detector circuit (113) detects when the second antenna (107) is attached to the electronic antenna switching system and generates a control signal (119) in response thereto. A switch (115) switches the active transmission path between the internal and the external antenna's transmission path in response to the control signal (119).
