Abstract: Methods, apparatuses, and systems for using Digital Signal Processing (DSP) to detect, measure, and/or compensate for, antenna load mismatch are described. One method provides a test sweep signal as digital input to a Digital-to-Analog Converter (DAC) in a transmit path ending with an antenna, and determines a transmit transfer function based on the digital input and digital output from an Analog-to-Digital Converter (ADC) in a loopback path which is electrically connected in parallel with a load impedance of the antenna. The determined transmit transfer function may be used for any of detecting, measuring, and compensating for, antenna mismatch.

Abstract: A method includes determining a quality indicator designating a quality of packet reception at a wireless local area network transceiver. A Modulation and Coding Scheme (MCS) index value is selected based on the quality indicator. A supply voltage provided to a radio frequency power amplifier is determined based on the quality indicator.

Abstract: Methods and apparatuses are provided for adjusting a transmission gain in a transmitter of an electronic device. A transmitted signal is received at a digital signal processor (DSP) of the transmitter. The transmitted signal is also transmitted through a transmission path of the transmitter resulting in a load impedance. A looped-back signal is received at the DSP via a loop-back path of the transmitter that returns from the transmission path. The DSP estimates the load impedance from the transmitted signal and the looped-back signal. The DSP sets the transmission gain of the transmission path based on the load impedance and saturation values for a load current and a load voltage.

Abstract: Micronized spray device for washing nasal and neighboring cavities including a bell-shaped body which forms an atomization chamber on the bottom whereof there is a region for containing a washing liquid in which a spray nozzle draws; the spray nozzle is associated with a compressed-air injector and is axially aligned with the inner outlet formed by the bell-shaped body. An outer skirt furthermore surrounds the bell-shaped body and forms an outer outlet which is located at the inner outlet and forms a chamber for collecting the catarrhal material that has been detached from the nasal cavities; the chamber is connected to the outside to vent the pressure generated during expiration. The outer skirt can be arranged in a first position, in which the outer outlet is spaced from the inner outlet so as to form an interspace that is connected to the collection chamber, and in a second position, in which the outer outlet overlaps the inner outlet.
