    Abstract: A portable radiotelephone with an integral voice recognition circuit is disclosed. Control of the voice recognition circuit is achieved with a foldable housing element which, in a closed position, covers an external keypad and control buttons. When the foldable housing element is in an open position, the portable radiotelephone is placed in an off-hook condition, the voice recognition circuit is activated, and the acoustic transducers are coupled to the voice recognition circuit. When the foldable element is in a closed position, the portable radiotelephone is placed in an on-hook condition, the voice recognition circuit is deactivated, and the electroacoustic transducers are coupled to the radiotelephone. A rapid closing and opening of the foldable element results in the voice recognition circuit being deactivated while the portable radiotelephone remains in the off-hook condition.

    Abstract: A wireless communication device stores in memory a record of a predetermined amount of a communication resource available to the user such as pre-paid call time, battery power or time before an expiry date . If this resource is depleted at an undesirable rate, indicating possible fraudulent use, the device is disabled. An undesirable rate includes the conditions where the rate is slower than normal, the resource is never depleted or is reset to a higher level. If the accumulated call time exceeds a preset limit then the device is also disabled. The device may be a cellular or cordless radiotelephone, pager, two-way radio, personal data assistant or personal computer using radio or infra-red wavelength signals. A disposable radiotelephone for outgoing calls only is described in detail which is thrown away or recycled when the communication resource is used up.

    Abstract: A portable radiotelephone with a keypad, alphanumeric character display, and hands free function is disclosed. A movable flip element of the housing covers a keypad and other control buttons when in a closed, on-hook, position and activates the illumination of the keypad, enables the display, and enables the hands free function when in an open, off-hook, position. The duration of keypad illumination and display activation are timed to reduce battery drain and the hands free function may be deactivated with a hookswitch flash.

    Abstract: The power control apparatus of the present invention is comprised of a local oscillator signal path coupled to a mixer (106) through a variable attenuator (107) and an IF signal path coupled to the mixer (106) through two variable attenuators (108 and 109) coupled in series. The IF signal path attenuators (108 and 109) are controlled by digital control circuitry (111) while the local oscillator path attenuator (107) is controlled by the control circuitry through a level shifter (110). The power level of the signal generated by the mixing of these two signals is less than the conducted output of the radiotelephone's power amplifier.

    Abstract: A radio arrangement and method allows a portable (210) and a mobile (212) to uniquely communicate on a radio system having at least one remote system site (114). The portable (210) has at least one information set (such as the radio's identification information and repertory dialing information) (356 or 360), and the mobile (212) is intercoupled therewith via a connector (214). The connector is used for transferring a code, which designates the information set, from the portable (210) to the mobile (212), whereby the mobile (212) adopts the information set of the portable (210) for subsequent communication. The arrangement offers an user having a portable, with its limited features and functions, to utilize all of the capabilities of the mobile.

    Abstract: The extended error correction process of the present invention error corrects a data message that has been transmitted a plurality of times. The process first receives the data message at least twice, logically combining the first and second messages received to form an error indication word. The error indication word is then used to locate the error locations in each message after which some of the errors are complemented, depending on the total number of errors found. The message is then decoded and used for transmit power changes, channel reassignment, to release a call, etc.
