Abstract: A scientific instrument for measuring neutral atmospheric conditions at satellite altitudes is provided. In an illustrative embodiment, the scientific instrument includes an ion gauge configured to measure ion pressure. The scientific instrument also includes a lid covering the ion gauge. The lid includes a plurality of slits. The scientific instrument also includes an aperture plate that includes an aperture opening. The aperture plate is configured to rotate such that each of the slits are periodically exposed by the aperture opening to allow a neutral beam flux to enter the ion gauge.

Abstract: Electromagnetic (EM) musical instrument systems and methods for configuring and using the instrument are provided. The EM musical instrument could include an EM resonant body to receive an excitation signal. The excitation signal varies the associated sound produced by the EM musical instrument. The EM musical instrument could also include a first circuit to convert an audio signal into an associated electrical signal, a second circuit to convert the electrical signal to an associated EM signal, and a third circuit to apply the EM signal to a body of an EM musical instrument to produce an associated sound. The EM musical instrument could include a body having a top plate of EM resonant material. The instrument could include a center medium defining a cavity coupled to a sound hole of the top plate and a bottom plate of EM resonant material coupled to the center medium. The instrument could further include a port coupled to the body and configured to apply the received excitation signal to the body.

Abstract: A method for generating electromagnetic (EM) music through excitation of an EM Musical Instrument is provided. An input queue, comprised of three sub-queues, receives three input audio queues. An EM excitation signal is generated based on the received input audio queues. The EM excitation signal is applied to the EM Musical Instrument. A measured response is generated, based on a response of the EM Musical Instrument to the EM excitation signal. Various time marks are marked in the measured response. Selected portions of the measured response are discarded based on particular time marks, generating a newly measured sample set. The newly measured samples are joined to a previously measured sample set of an output queue based on alignment of time marks. Various alternate embodiments and supporting systems are also provided.

Abstract: An electromagnetic (EM) musical instrument system includes an excitation signal generator to generate an excitation signal. The system also includes an excitation signal applier coupled to the excitation signal generator. The excitation signal applier receives the excitation signal and transmits a corresponding excitation signal to an EM musical instrument. The excitation signal applier is further configured to modulate the corresponding excitation signal to produce audio effects. An EM musical instrument, in response to receiving the corresponding excitation signal, generates an EM output signal associated with a produced sound. The system also includes an EM output receiver coupled to the EM musical instrument to receive the EM output signal.

Abstract: An electromagnetic (EM) musical instrument system is provided. The system comprises an excitation signal generator configured to generate an excitation signal. An excitation signal applier, coupled to the excitation signal generator, receives the excitation signal and transmits it to an EM musical instrument. The instrument receives the excitation signal and generates an EM ouput signal in response to the excitation signal. An EM output receiver receives the EM output signal. A method for generating electromagnetic music is also provided. An excitation signal is generated and applied to an EM instrument, comprised of a body comprising a shape and having EM characteristics that differ from one or more EM characteristics of a free space adjacent to the instrument, and a port coupled to the body, which receives and applies the excitation signal to the body. The responce of the instrument to the excitation signal is measured and recorded to generate an electromagnetic musical signal.
