摘要:
A near field communication loop antenna (308) is mechanically coupled to the cover (300) of a cellular telephone. The antenna (308) is coupled on the inside of the cover (300) between a keypad (302) and the cover (300), whereby the antenna (308) surrounds the keys (314) and is sandwiched between the keypad assembly (302) and the cover (300). A near field communication antenna (406) is coupled to the outside surface of the cover (300) surrounding a display and sandwiched between a lens (400) and the phone cover (300). A near field communication antenna embedded in the phone cover material, whereby the antenna surrounds either the keys or the display, is disclosed as well.
摘要:
A loop antenna (100) shares terminals with a thermistor on a battery. The battery (300) has at least two terminals (302 & 304) that connect to a thermistor (514). An electromagnetic wave radiating and receiving element (522) shares the at least two terminals (302 & 304) with the thermistor (514) but is electrically isolated from the thermistor (514) so that the thermistor (514) resistance can be measured while the electromagnetic wave radiating and receiving element (522) can communicate electrical RF signals via the at least two terminals with an RF circuit. A wireless communication device that uses the battery (300) and the loop antenna (100) is also disclosed.

摘要:
A button assembly (100) that includes a flexible electronic circuit (105) having a first side (110) and a second side (115). The button assembly also can include a biometric sensor (100) mounted to the first side of the flexible electronic circuit. Further, a switch (200) can be positioned at least proximate to the second side of the flexible electronic circuit. A stiffening member (305) can be attached to the first side or the second side of the flexible electronic circuit. The biometric sensor can be operable between a first position and a second position to effectuate opening or closing of the switch. The button assembly can operate the biometric sensor between the first and second positions utilizing pivotal, translational, and/or rotational movement.
摘要:
The embodiments of the invention concern a keypad (120). The keypad can include a membrane (143), at least one key with at least one flange 150 to overlap with at least one second flange of a second key (146), and at least one audio port opening (107) in the membrane for providing a passage of air from a transducer (101) positioned behind at least one key through the keypad to a main volume area (112). For example, the audio port opening can be in a region of the membrane between the keys, and the overlapping of the flanges obscures a view of at least one audio port opening.
