Abstract: Systems for monitoring audio quality of clustered devices are presented including: a number of wireless communication devices that are physically clustered; a number of audio interface modules (AIM) each electronically paired with each of the number of wireless communication devices to form an AIM/device pair, where the number of AIMs each receives and transmits wireless audio transmissions from each of the paired number of wireless communication devices; a data bus hub electronically coupled with the number of AIMs; and an electronic computing device for receiving and analyzing data associated with the wireless audio transmissions. In some embodiments, wireless audio transmissions are either a narrowband transmission or a wideband transmission. In some embodiments, the wideband transmission is a WiFi audio transmission and the narrowband transmission is a BLUETOOTH® transmission.

Abstract: Lidar is an acronym for Light Detection And Ranging. The technology may be used to measure distance by illuminating a target with a laser beam and performing analysis on the reflected laser beam light. In the atmospheric sciences, Lidar may be used to study the optical depth of clouds, the impact of aerosols on clouds, and the interactions between aerosols and clouds on the climate. The present application proposes a lidar-based technology using a diode laser (101) beam sent through a tapered semiconductor optical amplifier (106) and an axicon pair expander (108) wherein the laser light may be transmitted through a telescope (110) at an object to be studied. Upon striking the object to be studied, the laser (101) is reflected and recovered by the telescope (110). The reflected laser is then sent through a heated rubidium vapor cell (115) and a total detection channel (116) for analysis.
