Abstract: A respiratory ventilator device is described herein. The respiratory ventilator device includes an inhaled air assembly including an injector diaphragm housing including a flexible injector diaphragm, an extractor diaphragm housing including a flexible extractor diaphragm, a pneumatic compressed air assembly, and a control system operatively coupled to the pneumatic compressed air assembly. The control system including a processor programmed to execute an algorithm for operating the respiratory ventilator device including the steps of operating the pneumatic compressed air assembly in a first phase including the injector diaphragm and the extractor diaphragm in a center position, and operating the pneumatic compressed air assembly in a second phase including delivering compressed air into the injector diaphragm housing to move the flexible injector diaphragm to channel inhalation air from the injector diaphragm housing to a patient respiratory circuit.

Abstract: A respiratory ventilator device is described herein. The respiratory ventilator device includes an inhaled air assembly and a pneumatic compressed air assembly. The inhaled air assembly includes an injector diaphragm housing including a flexible silicone rubber diaphragm dividing an interior volume into an inhalation air chamber containing inhalation air and a compressed air chamber for containing compressed air. The pneumatic compressed air assembly operates in a compression phase delivering compressed air into the compressed air chamber to inflate the flexible silicone rubber diaphragm to reduce a volume of the inhalation air chamber and channel the inhalation air to a patient respiratory circuit, and operates in an expansion phase removing compressed air from the compressed air chamber to deflate the flexible silicone rubber diaphragm to increase the volume of the inhalation air chamber and receive the inhalation air from the supply of oxygenated air.

Abstract: A respiratory ventilator device is described herein. The respiratory ventilator device includes an inhaled air assembly, an exhaled air assembly, and a control system operatively coupled to the inhaled air assembly and the exhaled air assembly. The inhaled air assembly is coupled to a patient respiratory circuit and configured to channel a volume of inhalation air to the patient's lungs to assist in patient inhalation. The exhaled air assembly is coupled to the patient respiratory circuit and configured to remove air from the patient's lungs to assist in a patient exhalation. The control system is configured to operate the respiratory ventilator system in an inhalation mode and an exhalation mode.

Abstract: A system for use in generating electrical power, is described herein. The system includes an electrical power generator and a rotor assembly coupled to the electrical power generator. The rotor assembly includes a housing that defines a chamber containing a volume of liquid and a rotational device rotatably mounted to the housing. The rotational device includes a rotor coupled to a rotor shaft. The rotor shaft is coupled to the electrical power generator. The rotor includes a first portion positioned within the chamber and a second portion positioned outside of the chamber. The first portion of the rotor is submerged within the volume of liquid such that a upward buoyancy force exerted by the volume of liquid acts upon the first portion of the rotor to cause a rotation of the rotational device about an axis of rotation.
