Abstract: Systems, apparatuses, and methods are described for analyzing and optimizing an amplifier and/or a system of amplifiers based on a noise profile of the amplifier and/or the system of amplifiers. Changes in output power and noise profile of the amplifier and/or the amplifier system may be measured and analyzed, for example, by changing the input power to the amplifier system. Based on the changes to the noise levels and/or output power, the behavior of the amplifier and/or amplifier system may be remotely characterized and used to optimize the amplifier system.

Abstract: Systems, apparatuses, and methods are described for remotely reconfiguring the spectrum of a network based on a network profile associated with a service group. The service group may contain a group of modems that transmit and receive information over the spectrum of the network. The reconfigured spectrum may increase the network capacity of the network. The modems may continue to transmit and receive information while the reconfiguring is being implemented using intermediate bonding groups.

Abstract: A flow cell is provided for the analysis and/or microscopy of liquid or gas samples on the nanometer to micron scale. The flow cell preferably includes a thin membrane that is transparent to electrons and/or photons, thereby enabling the penetration of electrons or photons into a liquid flowing through the cell. Trenches are provided on either side of the membrane, which advantageously minimize fluidic resistance outside of the window area of the cell and also enable a faster response time in response to changes in external fluidic pressure. This feature enables active feedback using pathlength sensitive probes to stabilize the fluid flow to thin streams from nanometer to micron scale thicknesses with nanometer precision.
