Abstract: A system and method are provided for loading a sample into an analytical instrument using acoustic droplet ejection (“ADE”) in combination with a continuous flow sampling probe. An acoustic droplet ejector is used to eject small droplets of a fluid sample containing an analyte into the sampling tip of a continuous flow sampling probe, where the acoustically ejected droplet combines with a continuous, circulating flow stream of solvent within the flow probe. Fluid circulation within the probe transports the sample through a sample transport capillary to an outlet that directs the analyte away from the probe to an analytical instrument, e.g., a device that detects the presence, concentration quantity, and/or identity of the analyte. When the analytical instrument is a mass spectrometer or other type of device requiring the analyte to be in ionized form, the exiting droplets pass through an ionization region, e.g.

Abstract: Depositing a side slab structure on a cladding layer before etching a supporting dielectric prevents tapering of a silicon waveguide during etching of the supporting dielectric and a substrate. For example, the side slab structure may be deposited over the silicon waveguide and the cladding layer after etching the cladding layer. As a result, when an electronic device is integrated ex situ on the substrate, wave intensity and/or total internal reflection is improved, which improves an efficiency of the electronic device.

The method includes: transmitting an SRS of the first network from three antennas: a third antenna, a fourth antenna, and a fifth antenna in turn; and inputting the SRS and a second signal of the second network to a combiner, where the combiner combines the two signals and then transmits a combined signal from a multiplexed first antenna. In this way, the SRS is transmitted by using four paths in turn. This can ensure that transmission of the second signal is not interrupted in a process of transmitting the SRS of the first network by using the four paths in turn, so that a service of the second network is not interrupted.
