Abstract: A respiratory delivery system providing a bi-level pressure airflow. The system includes respiratory and pneumatic circuits. The respiratory circuit includes a respiratory gas supply, a patient interface, and a bi-level pressure regulator. The respiratory gas supply supplies a respiratory gas to the patient interface via a first conduit. The bi-level pressure regulator is coupled to the patient interface via a second conduit and is configured to cyclically alternate the respiratory gas passing through the bi-level pressure regulator between a low-pressure level and a high-pressure level. The pneumatic circuit includes a pneumatic gas supply and a pneumatic cycler configured to output a cycling pressure level. The cycler is coupled to the bi-level pressure regulator via a third conduit. The bi-level pressure regulator cyclically alternates the pressure level of the respiratory gas between the low-pressure level and the high-pressure level with the timing defined by the cycling of the pneumatic gas.

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.

Abstract: An unmanned aircraft includes: at least two generators generating forces to fly the unmanned aircraft, each including a rotor blade generating an airflow; a sensor detecting a tilt of the unmanned aircraft; and a processor controlling the generators to control flight of the unmanned aircraft. The processor: obtains an output force adjustment trigger for the generators; obtaining the trigger, causes each generator to individually operate at least until the tilt of the unmanned aircraft detected by the sensor satisfies a predetermined condition; determines a reference value related to an output force of each generator from a value related to the output force of each generator when the tilt of the unmanned aircraft satisfies the predetermined condition and a positional relationship between the generators; and controls the flight of the unmanned aircraft, using the reference values determined.

Abstract: An unmanned air vehicle is provided. The unmanned air vehicle includes one or more generators, each of which generates a force that drives the unmanned air vehicle to fly and also generates an airflow. Each of one or more first microphones is located in an external region that is not included in any of one or more first airflow regions. Each of the one or more first airflow regions corresponds to the airflow generated by one of the one or more generators. Each of one or more second microphones is located in the external region between at least one of the one or more generators and the one or more first microphones. A processor performs processing on one or more first signals output from the one or more first microphones and one or more second signals output from the one or more second microphones.

Abstract: An assist system includes a fist belt worn on an upper body part of a user, a second belt worn on a knee of the user, a wire, a motor coupled with a first end of the wire and disposed on the first or second belt, a drive controller that controls drive of the motor, a gyro sensor that is disposed on the second belt and that measures an angular velocity about a direction perpendicular to the direction of the wire, and a controller. When the angular velocity is greater than or equal to a first threshold with a first tension being applied to the wire using the motor, the controller outputs first information. A second end of the wire is coupled with the second belt when the motor is disposed on the first belt but coupled with the first belt when the motor is disposed on the second belt.

Abstract: An assistance apparatus includes first to eighth wires that couple an upper body belt to be worn on an upper body of a user to a first knee belt and a second knee belt to be worn above a left knee and a right knee of the user, respectively, and a motor. In a case of assisting the user in turning left, the motor generates, when a left leg is in a swing phase and a right leg is in a stance phase, a tension in each of the second, third, sixth, and seventh wires at an identical timing. In a case of assisting the user in turning right, the motor generates, when the left leg is in a stance phase and the right leg is in a swing phase, a tension in each of the second, third, sixth, and seventh wires at an identical timing.

Abstract: An unmanned air vehicle includes a generator that generates a flying force and also generates an air flow, a structural component, a microphone that outputs a first signal, a speaker, and a processor. The processor generates a second signal according to the first signal. The structural component surrounds a noise source of the generator, and includes a through-hole extending in a direction of the air flow. The through-hole is in a direction opposite to the direction of the air flow. An end, in the opposite direction, of the structural component corresponds to an end, in the opposite direction, of the noise source of the generator. An end, in the direction of the air flow, of the structural component extends, in the direction of the air flow, beyond an end, in the direction of the air flow, of the noise source of the generator.

When assisting users with walking, tensions equal to a first threshold value or greater are applied to one of the first and second wires and one of the third and fourth wires by the motor at different times. When detecting slacking of the upper-body belt, tensions equal to the first threshold value or greater are simultaneously applied to one of the first and second wires and one of the third and fourth wires by the motor.
