Abstract: An alerting device, such as a radio (10), activates, responsive to the times when an information signal (12) is received, a silent alert, via a vibrator (24), during a first predetermined time period, and an audible alert, via a loudspeaker (22), during a second predetermined time period, exclusive of the first predetermined time period. A radio user can configure the priority and the duration of the silent and audible alerts. The radio (10) also detects the reception of the information signal and the intercoupling between an accessory 51 to the radio 10. Responsive to the detection thereof, the radio (10) activates the audible alert. Thus, the user gains a high degree of confidence that the radio (10) will activate the proper alert in situations having a wide range of ambient noise levels and distances of the radio relative to the user's body.

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.

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: A leadless chip carrier for RF power transistors or the like is disclosed which includes a body of insulating material having two major surfaces and side walls joining the major surfaces. In a first embodiment, a pattern of conductive pads is deposited on one major surface. A pattern of conductive contact areas is deposited on the other major surface and distributed interconnecting portions of conductive material are deposited to connect the pads to the respective contact areas. In a second embodiment, larger pads and contact areas are provided on a beryllia substrate to provide a leadless chip carrier for RF transistors capable of handling 8 watts. In a third embodiment, a single slot is made conductive to provide the distributed interconnecting portion for one terminal, while in a fourth embodiment, the slot is changed to a plurality of small, tungsten-filled through holes to provide a virtually hermetically sealed leadless chip carrier for RF power transistors.
