Methods for adaptive data acquisition are disclosed herein. In one aspect, methods for adaptive data acquisition include performing a first sensing method on a signal having a plurality of components to determine the likelihood that a component is not a relevant signal component, retaining a portion of the signal components sensed using the first sensing method that are above a first threshold, performing a second sensing method on the signal components retained above a first threshold to determine the likelihood that a component is not a relevant signal component, wherein the second sensing method is more reliable than the first sensing method at determining the likelihood that a component is not a relevant signal component, and retaining a portion of the signal components sensed using the second sensing method that are above a second threshold.

Method of adaptive data acquisition

A device, method, and computer-readable medium are provided. The device includes, but is not limited to, an antenna configured to receive a multipath signal and a processor operably coupled to the antenna to receive the multipath signal. The processor is configured to determine a training signal transmitted from a second device to create the received multipath signal; sample the received multipath signal; and determine channel coefficients based on the sampled multipath signal and the determined training signal using a mixed-norm convex optimization process, wherein the channel coefficients characterize a channel associated with the multipath signal.

Determining channel coefficients in a multipath channel

The present invention provides sensors for use in detecting the presence or absence of analytes, systems incorporating the sensors, and methods for using the sensors. The sensors include thin membranes that undergo a detectable geometry change upon exposure to an analyte. In one exemplary embodiment, the sensors are small, thin-film membranes that include a stained semiconductor bilayer, wherein an interaction between the membrane and an analyte induces a detectable change in a strain-induced curvature of the membrane.
