Systems () and methods () for controlling operations of an electronic device. The methods comprise: using a rotary knob having a single rotatable part to select a first circuit to perform operations of the electronic device during a first time and to select a second circuit to perform operations of the electronic device during a second time; and using the single rotatable part of the rotary knob to additionally change preset functions for the first circuit at the first time and a second circuit at the second time, where a degree of rotation of the single rotatable part corresponds to a desired preset function input selected from a plurality of possible preset function inputs.

Rotary switch for a multi-channel communication device

A direct conversion receiver device may receive I and Q signals. The direct conversion receiver device may include a blind IQ balance circuit configured to balance the I and Q signals without a pilot signal, and a mixer coupled to the blind IQ balance circuit and configured to generate I and Q baseband signals using an operational frequency, the operational frequency being based upon bandwidth and modulation of the I and Q signals. The blind IQ balance circuit may include a first stage configured to generate an intermediate amplitude balanced Q signal based upon the I and Q signals, and a second stage coupled to the first stage and configured to generate phased balanced I and Q signals based upon the intermediate amplitude balanced Q signal and the I signal.

A communications system includes a radio frequency (RF) element () for transforming an input RF signal into at least one of a first conditioned RF input signal associated with a first frequency range and a second conditioned RF input signal associated with a second frequency range higher than the first frequency range. The system also includes a local oscillator (LO) circuit () for generating at least a first LO signal, the LO circuit having an operating frequency range spanning at least a portion of a first inclusive frequency range defined by a lowest frequency of the first frequency range and a highest frequency of the second frequency range. The system further includes a mixer () for generating a first intermediate frequency (IF) signal based on one of the first and the second RF input signals and the first LO signal, and an IF element () for conditioning the first IF signal.

Efficient receiver frequency plan for covering multiple frequency bands

A submersible loudspeaker assembly is provided. The loudspeaker assembly includes: a housing; a loudspeaker enclosed within the housing; an external diaphragm disposed adjacent to the loudspeaker. The external diaphragm is acoustically transparent when subject to ambient air pressure, but configured to flex towards the loudspeaker when submerged in water.
