  • Publication number: 20180274804
    Abstract: The present application relates to an apparatus for purifying and/or humidifying air, and a related method for purifying and/or humidifying air. The apparatus comprises a rotary filter (1), a fan (9, 10) for passing air through the rotary filter (1), and a reservoir (4, 5), and wherein the rotation speed of the rotary filter (1) and the settings of the fan (9, 10) depend on the ambient relative humidity and ambient gas pollutant concentration. The apparatus combines the feature of chemisorption with the use of a rotary filter (1), thereby providing an apparatus which is able to purify air and/or regulate the ambient humidity based on humidity levels and levels of a target gas pollutant in the air. The invention removes the need for a pump for liquid transport, removes the need for frequent and expensive filter changes by the user, and instead only requires the user to periodically refresh the filtration solution in the reservoir (4, 5).

  • Publication number: 20170350823
    Abstract: Methods and apparatus for determining levels of gaseous elements and optionally utilizing the determined levels to calibrate one or more sensors of an air purifier. For example, in some implementations a first image is captured of a colorimetric sensor device at the start of a sensing period and a second image is captured of the colorimetric sensor device at the end of the sensing period. The colorimetric sensor device includes at least one colorimetric sensor configured to change colors in response to reaction with a gaseous pollutant. Values may be determined based on the colors of the colorimetric sensor in the first and second images and the values may be utilized to determine a pollution value indicative of the amount of the gaseous pollutant to which the colorimetric sensor was exposed during the sensing period.

  • Publication number: 20170141938
    Abstract: A full-duplex transceiver with passive inter-modulation (PIM) cancellation using a feedforward filtering structure is presented. The transceiver can comprise a duplexer, a transmitter, a receiver, a summer, and a behavioral model module (BMM) that is used to estimate an estimated inter-modulated signal using a feedforward structure. The summer receives a receive signal output from the receiver and a compensation signal, and output a PIM compensated receive signal based on the difference between the receive signal output and the compensation signal. Further, the BMM receives the multiband transmit signal input and the PIM compensated receive signal, where the BMM tunes the transceiver to output a PIM compensated receive signal. The BMM generates an estimated compensation signal from an align term, lag terms, and lead terms of the transmitted signals. The embodiments disclosed herein can be applicable to communication networks experiencing PIM distortion in a radio frequency chain.
