Abstract: A system for detecting snoring. The system includes a first microphone to convert a first sound into a first signal, a second microphone to convert a second sound into a second signal, and a processor. The processor generates a third signal from the first and second signals that is representative of the first sound arriving at the first microphone and the second sound arriving at the second microphone to select first and second portions of the third signal, and to derive a metric from the second portion of the third signal. The first portion corresponds to the first sound arriving at the first microphone and the second sound arriving at the second microphone. The second portion contains only components of the first portion that have a frequency within a frequency range of interest. The metric indicates if the first portion of the third signal includes a component consistent with snoring.

Abstract: The shoe herein, in the form of a sandal, uses a combination of a midsole of varying thickness and nodules of varying diameters and heights to provide the requisite level of flexibility, support, and stimulation to the various regions of the foot. The walking action of the user creates waves of pressure across the foot, enhanced by the nodules, thereby increasing blood flow. Gradients of pressure that generate variations in the laminar flow of the foot bed lead to better circulation and perfusion of the capillary foot bed of the foot transection irrigation, allowing for better circulation and venous return.

Abstract: The insole described within uses a multiplicity of nodules of varying diameters and heights to provide the requisite level of flexibility, support, and stimulation to the various regions of the foot. These advantages are created while maintaining a low thickness, thereby allowing the insole to fit within a shoe without creating discomfort. Gradients of pressure that generate variations in the laminar flow of the foot bed lead to better circulation and perfusion of the capillary foot bed of the foot transection irrigation, allowing for better circulation and venous return.
