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: A radiotelephone system comprised of a radiotelephone-pair suitably intercoupled theretogether to permit transfer of data, such as NAM information, therebetween. A first of the radiotelephone-pair comprises a radiotelephone of conventional construction. A second radiotelephone of the radiotelephone-pair comprises a radiotelephone having circuitry to transmit efficiently an information signal upon a cellular, communication system of increased capacity. The data sequence contained in the first radiotelephone is transferred to the second radiotelephone to permit a communication link to be formed between the second radiotelephone and a cellular, communication network.

Abstract: A portable radiotelephone (200) adjusts its transmit power responsive to the position of a movable antenna (213). The antenna (213) is movable between a retracted (313) and an extended position (314). The portable radiotelephone (200) transmits at low power when the antenna (213) is retracted and at high power when the antenna (213) is extended. Additionally, the portable radiotelephone (200) can notify a remote base station of the change in transmit power at any time during transmission.

Abstract: A multiple battery, multiple rate automatic switching battery charger is disclosed. Two or more batteries are charged sequentially in a multiple pocket battery chargers in order to maintain a low peak power consumption level. One battery pocket is assigned a priority so that a battery placed therein will be charged first at a fast rate of charge. Upon completion of the fast charge cycle, the priority battery can be trickle charged during the fast charge of the non-priority pocket battery.
