Abstract: This document describes techniques and devices for type-agnostic radio frequency (RF) signal representations. These techniques and devices enable use of multiple different types of radar systems and fields through type-agnostic RF signal representations. By so doing, recognition and application-layer analysis can be independent of various radar parameters that differ between different radar systems and fields.

Abstract: An apparatus for analysing a sample of granular material, such as soil, is described. An elongated housing has a channel extending therethrough to define an optical path. A cavity is defined within the top of the housing to receive the sample, and a transparent sample-receiving surface is disposed within the cavity at a first elevation from the bottom of the housing. A lens assembly is positioned within the optical path at a second, lower, elevation. The lens assembly magnifies an image formed by light beams reflected by or transmitted through the sample. An image capturing device is disposed across the optical path at a third elevation that is lower than the second elevation. The image capturing device is thus lower than both the lens assembly and the transparent sample-receiving surface. A light source is mounted within the housing to emit light toward the sample-receiving surface.

Abstract: Epidermal electronics are sensors with mechanical properties matching human epidermis. Their manufacturing process includes photolithography and dry and wet etching within cleanroom facilities. The high cost of manpower, materials, photo masks, and facilities greatly hinders the commercialization potential of disposable epidermal electronics. In contrast, an embodiment of the invention includes a low cost, high throughput, bench top “cut-and-paste” method to complete the freeform manufacture of epidermal sensor system (ESS) in minutes. This versatile method works for many types of thin metal and polymeric sheets and is compatible with many tattoo adhesives or medical tapes. The resultant ESS is highly multimaterial and multifunctional and may measure ECG, EMG, skin temperature, skin hydration, as well as respiratory rate. Also, a stretchable planar coil made of serpentine ribbons can be used as a wireless strain gauge and/or a near field communication (NFC) antenna. Other embodiments are described herein.

Abstract: A device for manipulating liquid droplets comprises a structured surface including an array of larger pillars and a number of smaller pillars distributed among the larger pillars, where each of the larger pillars comprises a shape memory polymer having a glass transition temperature Tg. The structured surface has an undeformed initial configuration, and, upon compression of the larger pillars, the structured surface comprises a deformed configuration. The undeformed initial configuration is recoverable from the deformed configuration by heating the shape memory polymer at or above the Tg. When exposed to a liquid droplet, the structured surface comprises a first wettability in the deformed configuration and a second wettability in the undeformed initial configuration. Thus, the structured surface exhibits a dynamic wettability for manipulating liquid droplets.
