A pneumatic module has an air passage formed therein, including an air inlet to receive a source of pressurized air, a first subsystem with an air splitter in fluid communication with the air inlet, a second subsystem, and a third subsystem. The air splitter is configured to create two unequal air pressure fields to deflect an airflow from the air inlet to the second subsystem. The second subsystem is configured to create two unequal air pressure fields to deflect the airflow toward a first air bladder to inflate the first air bladder, and when the first air bladder reaches a first threshold air pressure, a first backpressure from the first air bladder causes the second subsystem to switch and deflect the air flow to a second air bladder. A second backpressure causes the air splitter to switch and deflect the airflow from the second subsystem to the third subsystem.

A training apparatus is disclosed, comprising: a top structure, a bottom structure, and a traction structure disposed between the top structure and the bottom structure, and wherein the traction structure is configured to be retractable along an axial direction of the top or bottom structure to achieve relative movement between the top structure and the bottom structure.

The present invention relates to an electronic headset system which is preferably wirelessly controlled, and is used to treat a tinnitus disorder. The system in an electronic headset and preferably an electronic communication device, such as a smartphone, laptop, tablet, desk top computer, server, and the like or any combination thereof. The electronic headset includes a treatment probe and emits complex signals which are converted into vibrations by the treatment probe and are transmitted to a users cochlea via the treatment probe communicating with the user's mastoid bone when the electronic headset is worn, thereby alleviating the symptoms of the user's tinnitus disorder.

A pneumatic system includes a passage to discharge compressed air and a sound attenuator including a first chamber in fluid communication with the passage and defined by a first wall through which the passage opens into the first chamber, a first surface of a second wall spaced from and opposite the first wall, and a sidewall extending between the first and second walls. The first chamber has a volume and includes a first opening in the sidewall. A second chamber is in fluid communication with the first opening and partially surrounds the first chamber. The second chamber is partially defined by a second surface of the second wall opposite the first surface and by the sidewall, and the second chamber has a volume and includes a second opening to exhaust air from the second chamber. The volume of the first chamber is less than that of the second chamber.
