Abstract: A remote control has a physical subsystem and a graphical subsystem. The physical subsystem has a hardware command processor and one or more physical input devices. The hardware command processor determines an input for an audio command based on activation of the one or more physical input devices. Further, the hardware command processor translates the audio command into a format understood by an audio monitoring system. In addition, the hardware command processor sends the translated audio command to the audio monitoring system so that the audio monitoring system adjusts one or more audio output devices based on the audio command. The audio monitoring system is remotely situated from the physical subsystem. Further, the graphical subsystem has a display screen and a display processor rendering a graphical user interface on the display screen.

Abstract: The present invention discloses an mixed signal RF drive electronics board that offers small, low power, reliable, and customizable method for driving and generating mass spectra from a mass spectrometer, and for control of other functions such as electron ionizer, ion focusing, single-ion detection, multi-channel data accumulation and, if desired, front-end interfaces such as pumps, valves, heaters, and columns.
