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).

Abstract: A segment-based approach for fast fourier transforms of input signals is provided for the generation of baseband signals. A FFT is performed individually for each of the segments from the input signal and the FFT result from each segment is accumulated to provide a final FFT for an input signal symbol. After the samples are received for one segment, a FFT can be performed to generate an intermediate FFT result while samples for the additional segment(s) are received. The system accumulates the intermediate result from the segments into a final FFT result that can be used to generate the baseband signal. Segment-based processing of an input signal can provide faster and more efficient processing to generate a baseband signal. Segment-based processing can also decrease the required size of the input buffers for antennas.

Abstract: An embodiment of a system and method for performing a numerical operation on input data in a hybrid floating-point format includes representing input data as a sign bit, exponent bits, and mantissa bits. The exponent bits are represented as an unsigned integer including an exponent bias, and a signed numerical value of zero is represented as a first reserved combination of the mantissa bits and the exponent bits. Each of all other combinations of the mantissa bits and the exponent bits represents a real finite non-zero number. The mantissa bits are operated on with a “one” bit before a radix point for the all other combinations of the mantissa bits and the exponent bits.

Abstract: A full-duplex transceiver with passive inter-modulation (PIM) cancellation using feedforward plus a feedback filtering structure is presented. The transceiver comprises a duplexer, a transmitter, a receiver, a summer, and a behavioral model module (BMM) that is used to generate an estimated inter-modulated signal using a feedforward plus feedback structure. The summer receives a receive signal output from the receiver and an estimated compensation signal, and outputs a PIM compensated receive signal based on the difference between the receive signal output and the estimated compensation signal. Further, the BMM receives the multiband transmit signal input and the PIM compensated receive signal, and tunes the transceiver to output the PIM compensated receive signal. The BMM generates the estimated compensation signal from an align term, lag terms, lead terms, and feedback of the transmitted signals.
