A wearable audio device includes a speaker, a wireless communications interface, an audio sensor configured to capture ambient noise in an environment occupied by a user wearing the wearable audio device, and memory having instructions stored thereon that, when executed by one or more processors, cause the one or more processors to perform operations including receiving, via the wireless communications interface, a first user input identifying a frequency range to be attenuated, generating an audio signal from the captured ambient noise, attenuating the audio signal to reduce an amplitude of one or more frequency components based on the frequency range, and causing the speaker to produce sound based on the attenuated audio signal.

Wearable audio device with selective frequency attenuation

Systems and methods are described for isolation, separation and detection of a molecular species using a low resource device for processing of samples. Methods include isolation, separation and detection of whole cells.

Low resource method and device for detecting analytes

Low resource processor using surface tension valves for extracting, concentrating, and detecting whole cells

The present invention provides simple and inexpensive assays for the detection of virtually any analyte in any sample that is in liquid form or that can be solubilized. The assays utilize the fluid dynamics of drop evaporation whereby soluble materials, including analytes and particles binding thereto, are drawn to the edge of the drop and ultimately form a concentrated residual ring. The presence or absence of certain reagents can then be detected through a number of different approaches.

Liquid drop diagnostic assays

A sensor device includes an optical limiting structure including a metal layer with at least one metal particle having a size no greater than about 1500 nanometers, and a phase-change material layer disposed adjacent at least a portion of the metal layer, the phase-change material layer including a phase-change material, and a dendritic-metal layer disposed over at least a portion of the phase-change material layer of the optical limiting structure, the dendritic-metal layer including an organic compound including branching chain amino acid groups attached to a metal structure. The optical limiting structure is configured to transition from a first optical state to a second optical state when the phase-change material is heated above a critical temperature, with transmittance of light at a predetermined wavelength through the optical limiting structure being lower at the second optical state of the optical limiting structure in relation to the first optical state of the optical limiting structure.
