Abstract: A vibration appliance includes a vibration-isolation structure which substantially reduces vibration felt by the user at the handle. The vibration motor is mounted to a vibration plate which carries the massage node. The vibration plate floats within the vibration appliance housing, being suspended by a flexible, elastomer membrane having contours such as curves or folds in it that provide freedom of movement of the vibration plate relative to the housing to which the flexible membrane is mounted. This arrangement can be thought of as the motor and vibration node being mounted on a flexible diaphragm that can move freely as if mounted to the housing by a bellows-like arrangement.

Abstract: In some embodiments, the present disclosure provides a method to process high pressure air into low pressure breathing air for one or more sealing and locking helmets and/or one or more air respirators. Other embodiments include a system configured to perform such a method and a manufacturing process of making such a system. In some embodiments, the breathing system automatically fills a local reserve bottle by pressure equalization. In this regard, the secondary supply bottles will fill the backup bottle when the console module operator (CMO) connects the secondary air supply to the system. The backup bottle will then be isolated from depletion during normal operation by means of a check valve to prevent back flow of the emergency cylinder into the secondary air supply. The local reserve bottle will protect against loss of air on any of the high pressure air hoses.

Abstract: A method is provided for reducing the risk of sustaining a traumatic brain injury caused by a traumatic event that includes identifying a subject at risk of sustaining a traumatic brain injury, and then precisely increasing the partial pressure of carbon-dioxide (CO2) in the blood of the subject (pCO2). This method can be applied to raise the CO2 and pCO2 to improve orthostatic hypotension in conditions such as dysautonomias (like Positional Orthostatic Tachycardic Syndrome POTS) and to facilitate the drive to breathe in conditions like Central Sleep Apnea (CSA) and Sudden Infant Death Syndrome (SIDS). The pCO2 of the person is increased by placing a breathing apparatus over the mouth of the person through which the person must breath, wherein the breathing apparatus includes an enlarged dead space volume in which expired CO2 collects to be inhaled or re-breathed by the person on the next inhalation.

Abstract: A respiratory system provides bi-level pressure using a dual pressure device in fluid communication with a source of breathable gas and a patient interface. The dual pressure device includes a pipe submerged in a liquid in a container, and a float disposed along the pipe. The float cyclically moves up and down the pipe between a lower position and an upper position as the floats buoyancy changes. The floats position along the pipe causes the gas pressure level to alternate between a baseline pressure level and a peak pressure level by selectively blocking and unblocking an opening in the pipe, and selectively capturing and releasing gas from the float, with the maximum gas pressure being limited by the setting on a pressure relief valve.
