Visual interfaces for telephone calls
Incoming calls are received from audio capable devices. A call processing server receives an incoming call from an audio-capable device to a destination number, and detects availability for an ancillary source device linked to the audio-capable device. A set of data is provided to the ancillary source device. The set of data specifies graphical menu options for functions supported by the call processing server. The ancillary source device provides an indication of a selection of one of the graphical menu options. In response to the indication, a call transfer for the incoming call is implemented.
Integrated multiband antenna
An end fed dipole antenna on a circuit board configured to be a multiband, portable radio antenna has, among other features, an integrated diplexer for operating the antenna in multiple frequency bands.

Method of eliminating resonances in multiband radiating arrays
A multiband radiating array according to the present invention includes a vertical column of lower band dipole elements and a vertical column of higher band dipole elements. The lower band dipole elements operate at a lower operational frequency band, and the lower band dipole elements have dipole arms that combine to be about one half of a wavelength of the lower operational frequency band midpoint frequency. The higher band dipole elements operate at a higher frequency band, and the higher band dipole elements have dipole arms that combine to be about three quarters of a wavelength of the higher operational frequency band midpoint frequency. The higher band radiating elements are supported above a reflector by higher band feed boards. A combination of the higher band feed boards and higher band dipole arms do not resonate in the lower operational frequency band.
