A method of manufacturing a portion of a portable electronic device includes forming a fibrous laminate sheet to provide a laminate body, and connecting a rim with the body. The rim includes a connector for coupling with a complementary part.

Method of manufacturing portable electronic device

Method, system and apparatus for cooling a mobile device is provided. The device comprises: a housing comprising one or more apertures; a heat producing device; a cooling apparatus adjacent the heat producing device, the cooling apparatus comprising: an inlet; an outlet; and, a thermal pump configured to: draw air from the inlet to the heat producing device to form heated air, and exhaust the heated air from the outlet; and, one or more carbon nanotubes, a respective entrance of each of the one or more carbon nanotubes located at the outlet of the cooling apparatus, and a respective exit of each of the one or more carbon nanotubes terminating at a respective aperture of the one or more apertures, so that the heated air is vented through the one or more apertures.

Method, system and apparatus for cooling a mobile device

A device having an electrical plug, such as a charger device, includes a locking member coupled to a carriage that is movable into a housing. Prongs of the device are movable between a retracted position and an extended position along two different travel paths by actuating the prongs or by actuating the carriage.

Charger device for a portable electronic device

A key assembly for an electronic device having a one-piece keycap and an electronic device having such a keycap are provided. In accordance with one embodiment, there is provided a key assembly for use in an electronic device, comprising: a keycap having a plurality of rigid key portions separated by mechanically deforming portions; and a flexible member having opposed first and second sides, the first side having a plurality of key stems which are attached to the plurality of key portions, the second side having a plurality of actuators for actuating dome switches of the electronic device.

Key assembly for a handheld electronic device having a one-piece keycap

A function of an electronic device is selected by detecting a resonant frequency generated by a tapping on a selection region of a device housing. The function of the device is selected based on the detected resonant frequency.

Function selection by detecting resonant frequencies

Hybrid keypad apparatus are disclosed herein. An example dome sheet carrier apparatus disclosed herein includes a first carrier portion having a first plurality of domes and a second carrier portion adjacent the first carrier portion. The second carrier portion has a second plurality of domes different than the first plurality of domes, where each of the second plurality of domes has a conductive material adjacent an apex of the second plurality of domes.

Hybrid keypad apparatus

Hybrid keypad apparatus are disclosed herein. An example hybrid keypad apparatus includes a dome-switch assembly having a first plurality of domes composed of a first material and a second plurality of domes composed of a second material different from the first material. A carrier couples the first and second plurality of domes.

A keypad suitable for use with a mobile communication or a handheld device. The keypad includes an actuator component formed from multiple materials and comprises a plurality of actuators, a sealing bead and/or a light guide. The sealing bead is formed from a flexible or compressible material such as silicone rubber. When the keypad is installed the sealing bead is compressed against the mounting surface in the device and provides a seal for the keypad against environmental agents such as moisture, dust and/or electrostatic discharges.

Keypad with water and dust protection

A system for enhancing functionality of a mobile device comprising: the mobile device, wherein the mobile device includes: a radio subsystem; a processor adapted to interact with the radio subsystem; a user interface; a short range communications system; and a battery adapted to power the mobile device; and an accessory adapted to communicate with the mobile device, the accessory including: at least one processor; a radio subsystem communicating with the processor; and a short range communications system adapted to communicate with the short range communications system of the mobile device, wherein the radio subsystem of the mobile device differs from the radio subsystem of the accessory.

Radio accessory for a mobile device

The invention provides a portable communication device and enclosure therefor where separation of its antenna from the user's head is facilitated. The device comprises: a case; a speaker port; an antenna located in the bottom of the case; and a spacer located on the front of the case for resting against a cheek of a user of the device. When the device is held against the head of a user of the device with the spacer resting against a cheek of the user, the spacer biases the bottom of the device away from the user's head. The spacer may be located at a distance from the speaker port on the front of the case to comply with a Cellular Telephone Information Association (CTIA) test plan for Mobile Station Over the Air Performance.

Antenna spacer for a handheld communication device

A charger unit includes: a housing, prongs for engaging an electrical outlet, the prongs being coupled to one another by a cross-member and being movable relative to the housing between a retracted position in which the prongs are received in the housing and an extended position in which the prongs protrude from the housing, the prongs being biased toward the extended position, a locking arm comprising a first end, a cut out for receiving the cross-member when the prongs are in the retracted position and a second end for abutting the cross-member when the prongs are in the extended position, the first end of the locking arm being coupled to a carriage and the cutout being provided between the first end and the second end, the locking arm being movable by the carriage into and out of engagement with the cross-member and the locking arm being biased toward the passage.

Electrical device for a portable electronic device

A piezoelectric assembly is described. In accordance with one embodiment, there is provided a piezoelectric assembly comprising: an electrode assembly; a signal electrical connector electrically connected to the electrode assembly; a reference electrical connector electrically connected to the electrode assembly; and a spacer positioned about a perimeter of the electrode assembly and disposed between the signal electrical connector and the reference electrical connector such that no electrical communication is provided between the signal electrical connector and the reference electrical connector through the spacer; wherein a humidity barrier space is defined between the signal electrical connector, the reference electrical connector and the spacer, and wherein the electrode assembly is disposed in the humidity barrier space.

Piezoelectric assembly

A method of manufacturing a portion of a portable electronic device includes forming a glass fiber laminate sheet to provide a formed glass fiber laminate body, and overmolding a rim on the body. The rim includes a connector for coupling with a complementary part of the portable electronic device.
