Abstract: In some aspects, the techniques described herein relate to an apparatus including: at least one foot board settable to one or more predetermined inclination angles; at least one rotating base rotatable through one or more predetermined ranges of rotation; and a stationary base, wherein the stationary base supports the at least one foot board and the at least one rotating base such that a user placing a foot on the at least one foot board can flex or extend the foot at the one or more predetermined inclination angles and can pronate or supinate the foot through the one or more predetermined ranges of rotation.

Abstract: A method of steps and a system of components which detects and responds to smoke, CO, and/or fire hazard emergency alarm signals (loud audio noise and/or bright strobe lights) and then provides a shut-off of electrical power and/or fuel gas (e.g. natural gas or propane) as well as other types of power and energy for safety's sake. The present invention is improved over the current product offerings and state of the art through increasing the reliability of alarm signal detection by utilizing redundancy and providing primary and backup sensor functionality for both of the possible commonly intended alarm signal outputs instead of monitoring for just one. This invention also includes a method of steps and a system which further improves reliability by adding additional redundancy and backups through detecting and responding to the unobvious but real by-product alarm signals which are: 1. the vibration of the audible alarm mechanism and 2. the electricity flowing in or to the activated alarm.
