Abstract: A device, system and method for generating and rendering customized application data for first responders is provided. A device receives an assignment identifier and input to access a web-based application using a link and a browser application. The device incorporates the assignment identifier into the link to generate a customized link and launches the browser application using the customized link to retrieve customized application data indicative of the web-based application customized according to the assignment identifier. The device controls a display screen to render the customized application data in the browser application. A server receives the customized link from the device, generates the customized application data, indicative of the web-based application customized according to the assignment identifier, and transmits the customized application data to the device.

Abstract: A device and method for correcting in-phase and quadrature phase (IQ) baseband components to drive a speaker is provided. The device: controls a local oscillator of an RF downmixing device to a plurality of baseband frequency offsets over a range that includes a given baseband frequency offset; determines, at the plurality of baseband frequency offsets, for a received RF signal, amplitude ratio error and phase error for respective IQ baseband components of the received RF signal; generates, using the amplitude ratio error and the phase error for the respective IQ baseband components, for the given offset, filter coefficients for a given baseband frequency range which compensates for respective amplitude ratio error and respective phase error for the given baseband frequency range; and filters, with the filter coefficients, IQ baseband components of the received RF signal, with the local oscillator operating at the given offset, to generate corrected IQ baseband components.
