  • Publication number: 20200170878
    Abstract: A device and method coupled to a therapy garment to apply pressure and repetitive compression forces to a body of a person has a positive air pulse generator and a user programmable time, frequency and pressure controller operable to regulate the duration of operation, frequency of the air pulses and a selected air pressure applied to the body of a person. The air pulse generator has rigid displacers that are angularly moved with power transmission assemblies to draw air into the air pulse generator and discharge air pressure pulses to the therapy garment.

  • Patent number: 10156235
    Abstract: A supercharged internal combustion engine has a supercharger operable to selectively supply a mass of air from below through above atmospheric air pressure according to the operating requirements of the engine. The supercharger has a shuttle combined with a throttle valve that controls the mass of air directed to an air mass bypass opening and supplied to the internal combustion engine. The shuttle has rollers that ride on rails that allow the shuttle to move to open and close the air mass bypass opening in communication with a casing that directs a mass of atmospheric air and a bypass mass of air interfused with the mass of atmospheric air to an air mass inlet of the supercharger.

  • Patent number: 8813492
    Abstract: A diesel or diesel-like internal combustion engine drivably connected to a variable internal compression ratio supercharger that supplies varying amounts of air to the engine responsive to the load requirements of the engine. The supercharger has a pair of rotors concurrently driven by the engine to move air to the engine. A slide assembly associated with screw rotors is movable with a controller relative to the rotors to bypass air to atmosphere and regulate the amount of air and pressure of the air compressed by the screw rotors to the engine to increase the engine's efficiency.

  • Patent number: 8740824
    Abstract: A vest for a human body has an air core coupled to a pulsator operable to subject the vest to pulses of air which applies and releases high frequency pressure forces to the body. The pulsator has two diaphragms connected to a brushless electric dc motor with rotary to reciprocating linear motion transmitting mechanisms comprising scotch yokes having anti-lash assemblies operable to generate air pulses in an air pulsing chamber. The diaphragms also increase the pressure in a manifold chamber. A check valve connects the manifold chamber with a pulsing chamber to allow pressurized air to flow from the manifold chamber into the pulsing chamber. An air flow control valve in communication with the manifold chamber is used to adjust the pressure of the air in the manifold and pulsing chambers. A programmable motor controller adjusts the duration of operation and speed of the motor to vary the operational time and frequency of the air pulses.

  • Patent number: 8539769
    Abstract: An internal combustion engine drivably connected to a variable displacement and variable internal compression ratio supercharger that supplies varying amounts of air to the engine air intake manifold that can range selectively from below through above atmospheric pressures responsive to the power requirements of the engine. The supercharger has a pair of rotors concurrently driven by the engine to move air to the engine. A slide assembly associated with screw rotors is movable with a controller relative to the rotors to bypass air to atmosphere and regulate the amount of air and pressure of the air above atmospheric pressure compressed by the screw rotors to the engine to increase the engine's efficiency. When operating at part-load unboosted, a throttle valve is operable to control the air mass flowing to the air intake manifold below atmospheric pressure to control the power of the engine.
