A dual-band antenna assembly for use with an electronic device comprises a substrate and first, second, third, and fourth antenna filar elements. The substrate includes a side wall forming a cylindrical shape. The first, second, third, and fourth antenna filar elements are positioned diagonally on the side wall and equally separated from one another. Each antenna filar element includes a first arm configured to receive wireless signals in a first frequency band and a second arm electrically connected to the first arm, positioned adjacent to the first arm, and configured to receive wireless signals in a second frequency band. The first arm has a length that is greater than a length of the second arm and has a portion which wraps around the second end of the second arm thereby capacitively coupling the portion of the first arm with the second arm.

A portable GPS/radio unit () communicates over a wireless radio network () with at least one other such unit. The unit () may transmit radio signals over the network () indicative of the unit's location. The unit () includes a single, push-to-talk button () that may be pressed to both transmit a voice communication and to initiate transmission of location data. The unit () also includes a 'polling' function that requests location data from other units, an auxiliary coding system that codes or encrypts all transmitted data, and an emergency message feature that facilities the transmission and receipt of emergency messages.

Combined global positioning system receiver and radio

Embodiments of the present invention provide a tracking apparatus () and method that are operable to efficiently track an animal. The tracking apparatus () is operable to be worn by an animal, determine its current geographic location, and transmit information relating to its current geographic location to an external device such as a portable navigation unit (). The navigation unit () is operable to display a representation of the geographic location of the tracking apparatus () for consideration by a user.

Animal tracking apparatus and method

Methods, systems, and devices for location specific alerts. The method can include determining one or more positions using a navigation device. One or more weather signals received on at least a first channel of the navigation device, where the one or more weather signals include location information, can be compared to the one or more positions. From the comparison, a weather alert can be generated in the navigation device. Determining the one or more positions further includes determining the positions from a global positioning system (GPS) enabled navigation device.
