Abstract:
The present invention relates to electronic devices such as mobile devices, and methods of operating such devices. In one embodiment of the invention, the electronic device includes first and second temperature sensors positioned at different respective locations on the electronic device and at least one processing device. The first and second temperature sensors respectively output first and second signals indicative of the respective temperatures experienced at those respective sensors. The at least one processing device (i) receives the first and second signals respectively from the first and second temperature sensors respectively and generates based thereon an indication of a difference or a relationship between the first and second temperatures, and (ii) determines an operational context of the electronic device based at least in part upon the difference. In an additional embodiment, other sensor information from one or more other sensors is taken into account in determining the operational context.

Abstract:
A communication device (10 or 50 or 200) having a customized antenna arrangement (14 or 54) for the communication device formed on a first housing portion (201 or 203) having etched thereon customized metallization providing optimized performance for frequencies most often used by a user and a second housing portion (201 or 203) for mating with the housing portion where the first housing portion and the second housing portion contain or enclose at least a substantial portion of a transceiver (12) coupled to a controller (30). Other embodiments are disclosed.
Abstract:
A multimode communication device (10 or 50) having an antenna arrangement (14 or 54) having a first antenna (18) operational in both low bands and high bands, a second antenna (20) operational in high bands, a tuner (26) coupled to the first antenna adapted to adjust matching elements to modify return loss to lower reflected power, a switching mechanism (28) for selecting between the first antenna and the second antenna, and a controller (30) coupled to the switching mechanism and the tuner.
