Abstract: The present disclosure provides one or more embodiments involving a novel bedding system that, for example, promotes control of a blanket, a sheet, and/or a pillowcase. The present disclosure improves and maintains bedding placement when one is in a bed, such that a blanket does not become congested or misaligned in relation to a top sheet or in relation to the bed itself. One or more embodiments of the bedding system include buttons located on the sheet and/or pillowcase that feed through holes on the blanket and the opposite side of the pillowcase, thereby securing the sheet to the blanket and allowing the pillowcase to reliably encapsulate a pillow contained within.

Abstract: An Atmospheric Turbulence Detector utilizes a sensor to detect noise and extracts infrasound having frequencies below a specified infrasound frequency. A threshold is computed from the detection of infrasound in the vicinity of the sensor prior to the arrival of infrasound from the turbulence and an alarm is given when the infrasound from the turbulence exceeds the computed threshold. Range and direction of atmospheric turbulence are determined with the utilization of two sensors, measuring the phase difference between the detected infrasound of the two sensors, measuring amplitude differences of the infrasound detected at two separate locations.
