PDA with integrated address book and electronic map waypoints

A wireless communication device (101), such as a radiotelephone or a pager, comprises a signal generator (200), a radiator (202), a sensor (204) and a controller (206) to form an electromagnetic wave proximity sensor (201). The signal generator (200) generates a signal (210). The radiator (202) radiates the signal (210) to produce an electromagnetic field (212) near the radiator (202). The electromagnetic field (212) changes by a predetermined amount responsive to the proximity (214) of the radiator (202) to a predetermined object (216), such as a human body (232), external to the wireless communication device (101). The sensor (204) provides an indication (218) of the predetermined amount of change in the electromagnetic field (212). The controller (206) controls circuitry (208), such as a tactile alert device (416) and an audible alert device (418), in the wireless communication device (101) responsive to the indication (218) of the predetermined amount of change in the electromagnetic field (212).

Wireless communication device having an electromagnetic wave proximity sensor

A protective enclosure for protecting and enclosing an electronic device. The protective enclosure provides communication capabilities with the electronic device while the electronic device is enclosed and protected by the protective enclosure. The enclosure also provides an alert upon an unsolicited activation of the electronic device and allows the user to communication with electronic device without removing the electronic device from the enclosure.

Enclosure for wireless communication device

A protective cover for handheld devices. The protective cover containing a hardened plastic protective inner layer and a soft outer layer. The protective cover containing at least one cavity for mounting the associated segment of the handheld device therein and at least one fitted notch to secure the piece to the associated segment. The protective cover further containing at least one window for providing exposure to the surface of the associated segment.

Handheld device protective case

A system and a method are provided for activating one or more security functions of a mobile electronic device. The system and method provide for the activation of one or more security functions when the mobile electronic device is stored in a mobile electronic device holder. Security functions include, for example, closing a data item currently being displayed on the mobile electronic device, erasing decrypted information stored on the mobile electronic device, locking the mobile electronic device, and performing a secure garbage collection operation.

System and method of security function activation for a mobile electronic device

A device used with a portable radio (10) and associated carrying case (30) which can automatically adjust radio control functions such as audio output, DTMF tone level mode telephone hang-up or illumination levels of the radio depending on the radio's position in relation to the carrying case. The radio (10) includes a hall effect switch (14) used to signal the a microprocessor within the radio when actuated. A magnet (38) located within the case (30) actuates the hall effect switch (14) when the radio (10) is placed within the case (30). The microprocessor is then signaled to change radio function aiding the user in the operation of the radio (10) depending on the its position.
