Abstract: Computer-implemented methods and systems are disclosed for enabling seamless application context transition across a plurality of computer devices; enabling one or more given functions of an application residing on a computer device to be available when the computer device is offline, exposing a business service across a plurality of applications executing on a computer device; enabling authentication, data integrity, and secure data transmission; enabling seamless integration capabilities for applications; enabling archival of data stored locally on the device; and enabling device clustering, among other features.

Abstract: A method for controlling audio gain balance in a multi-mode communications device (200) includes providing (201) microphone audio input to the multimode communications device. The audio is supplied to an amplifier gain stage while a dynamic instantaneous energy value of the audio input is computed (203) when in a first operational mode such as an analog mode. A predetermined gain algorithm is processed (207) representing an audio input when in a second mode such as a digital mode using the energy value. The audio gain stage in the multi-mode communications device is then adjusted (209) so that audio gain when in the first mode substantially approximates an audio gain when in an second mode. This provides a consistent audio amplitude output when receiving the first and second modes in a radio receiver.

Abstract: A modulator (102) modulates a plurality of symbols to create a modulated signal. A transmitter is coupled to the modulator (102). The transmitter transmits the modulated signal if the modulated signal is above a threshold. A minima enlarger (104) is coupled to the modulator (102). The minima enlarger (104) computes an adjustment to the plurality of symbols if the modulated signal is below the threshold. A summer (106) is coupled to the modulator (102) and the minima enlarger (104). The summer (106) adds the adjustment to the plurality of symbols if the modulated signal is below the threshold.
