This paper describes the Sound Scope Headphones which enable the user to control an audio mixer through natural movements of the head and hands. This allows musical novices to interact closely with the music they listen to. Commercial audio mixers are too complicated for musical novices to properly control the multi-channel volumes and panpots. Our headphone device controls an audio mixer using...

performance while requiring a considerably less LO power than is required of Class III diode ring mixers having comparable performance [6]. However, the topology has provided little improvement in the NF of earlier active mixer topologies. In the lossless feedback active mixer, an input IF (or RF) signal having amplitude A and frequency ω S is applied differentially to the input terminals of a ...

This paper describes a doubly balanced Gilbert Cell mixer designed in BJT and CMOS technology to operate within 0 to 5 V. A 100 mv input signal was applied at both RF and LO port at different frequencies and their simulation curves were studied for a multiplier. The design done in BJT was taped out for fabrication and the chip on its return from foundry, was tested for its results. A comparison...

This paper presents an analysis of the stream cipher Mixer, a bit-based cipher with structural components similar to the well-known Grain cipher and the LILI family of keystream generators. Mixer uses a 128-bit key and 64-bit IV to initialise a 217-bit internal state. The analysis is focused on the initialisation function of Mixer and shows that there exist multiple key-IV pairs which, after in...

We have developed a novel micro-mixer using a biological molecular ATP motor. The micro-mixer was constructed from arrays of chromatophore-embedded delta-free F(0)F(1)-ATPases, where the delta-free F(1) part acted as a rotator to mix solutions, and the F(0) part was driven by light. Confocal microscope studies indicated that the micro-mixer did not touch directly on the fibrin labeled with FITC...

Laminar flow and mixing of a Newtonian fluid are characterized in a four-element Koch-Glitsch SMX static mixer. The computational analysis on a fine, unstructured mesh containing more than 3.5 million tetrahedral elements led to high-resolution numerical data for ®elocity and pressure. Computed pressure drops agreed excellently with those in the literature. The flow in this static mixer is esse...

The paper presents analysis and design of a -band subharmonic mixer (SHM) with high conversion gain. The SHM consists of a local oscillator (LO) frequency doubler, RF pre-amplifier, and single-ended mixer. The SHM has been fabricated in a high-speed InP double heterojunction bipolar transistor (DHBT) technology using coplanar waveguide structures. To the best of our knowledge, this is the first...

Efficient models based on behavioural modelling techniques are needed for RF and microwave mixers in order to check the performances of communication systems. Here, we propose a model consisting on the cascade connection of an input equivalent filter, characterising the linear transmission and reflection memory effects, and an ideal nonlinear mixer model, providing the frequency translation and...

This study investigated the status of mechanized power and self-propelled rice cultivation machinery in Guilan Province in northern Iran. The raw data was obtained from 2013 statistics of the Agricultural Jihad Organization of Guilan province. Power per unit of area, mechanization level, area per unit of self-propelled machinery, and mechanization requirement were calculated for eastern, wester...
