Abstract: Lightweight wheeze detection methods and systems for portable respiratory health monitoring devices conserve computing resources in portable respiratory health monitoring devices by employing lightweight algorithm that calculates a partial STFT image of a respiratory signal that includes all data points necessary for wheeze detection but excludes many data points that are unnecessary for wheeze detection. The methods and systems provide substantial savings in computing resources while still ensuring every wheeze in a respiratory signal is detected.
Abstract: Methods, devices, and systems are provided facilitating security within a network managed by a central coordinator. In some embodiments, the exchange of security keys is performed within one or more time slots that are defined by the central coordinator and known to stations exchanging these security keys. Furthermore, security, e.g., association may be initiated by one user action.
Abstract: An electrical pressure-sensitive reflective display includes an array of display pixels, each with a transparent top surface, first electrode, second electrode, an elastic polymer medium, and metallic nanoparticles distributed in the elastic polymer medium. When a first voltage potential is applied between the first and second electrodes of each display pixel, a first color is reflected from the incident spectrum of light, assuming no pressure is applied on the top surface of each display pixel. When the top surface of a first display pixel is deformed in response to an applied pressure, the elastic polymer medium in the first display pixel is compressed, decreasing the metallic nanoparticle-to-metallic nanoparticle mean distance in the first display pixel. In response to decreasing the metallic nanoparticle-to-metallic nanoparticle mean distance, the color reflected from the incident spectrum of light by the second display pixel is changed from the first color to second color.

Abstract: A method for base station reselection in a wireless communications system is disclosed. The method may determine a first indication of signal strength for a first signal sent from a first base station and received by a user equipment (UE). The method may also determine a second indication of signal strength for a second signal sent from a second base station and received by the UE. The method may further determine a relative signal strength based on the first indication of signal strength and the second indication of signal strength. The method may also determine a Q factor based on the relative signal strength. The Q factor may be an indication of when base station reselection should be performed.
