Abstract: A method and apparatus to reduce communication device peak current for alert tones are disclosed. A portable device may include a processor coupled to a transceiver and an alert tone controller coupled to the processor. The transceiver may be configured to process an audio signal representing an alert tone. The processor may be configured to determine whether an audio volume level setting exceeds a predetermined threshold. The alert tone controller may be activated based on the determination. The alert tone controller may be configured, based on the activation, to reduce an audio signal by adjustment to a peak-to-peak amplitude of the audio signal and generate an adjusted audio signal by a restriction on the maximum amplitude of the reduced audio signal.

Abstract: Methods and systems are provided in this disclosure for operating an electronic device. The electronic device includes a user interface, a microphone, and an electronic processor. The electronic processor determines whether a user assistance restriction is established for a current functional operation of the electronic device. The microphone captures an audio stream and the electronic processor analyzing the audio stream to identify spoken words captured by the microphone. The electronic processor detects a violation of the user assistance restriction for the current functional operation of the electronic device based at least in part on a correlation between one or more of the identified spoken words captured by the microphone and a current functional operation of the electronic device. The electronic processor adjusts one or more operations of the electronic device in response to detecting the violation of the user assistance restriction.

Abstract: A user interface apparatus and method are provided for gloved and non-gloved touch sensitive button actuation. A user interface (100) embodied as a body wearable harness (104) provides a touch button control system having an activation button (120) and functional touch sensitive control buttons (108, 110, 140). The activation button (120) has a capacitive touch element (130) associated therewith that determines gloved or non-gloved operation based on a capacitive measurement taken in response to a finger input to the button. A plurality of control buttons (108, 110, and 140) are automatically assigned increased sensitivity levels in response to detected gloved mode operation in accordance with the measurement. The increased sensitivity levels allow various radio functions to be accessed by a gloved finger input during gloved mode operation with increased reliability. Additional control button identification can be added through the addition of vibrational alerts. Display and screen type control buttons can further be combined into larger and fewer buttons for ease of gloved landing.

Abstract: A method and circuitry for detecting a touch on a device is provided herein. Touch-sensing circuitry comprises two antennas coupled to two voltage-controlled oscillators (VCOs). A phase locked loop (PLL) is provided coupled to the VCOs. The PLL compares a VCO output with a frequency source (temperature controlled crystal oscillator (TCXO)), and outputs a tuning voltage (steering voltage) for the VCO that is based on the difference between the VCO frequency and the TCXO frequency. The steering voltages for each VCO are compared, and a decision is made as to whether or not a touch has been made to the antennas. If the antennas have been touched, a location of the touch is determined based on a difference in the steering voltages of the two VCOs.
