A personal respiratory isolation system (PRIS) provides a personal, negative pressure environment for a patient or user that reduces contamination and spread of pathogens exhaled by the patient into the environment. The PRIS includes an enclosure to receive the patient's head (such as a hood and a drape) and a negative pressure source which draws ambient air into the interior of the enclosure and draws air within the enclosure's interior (including the exhalations of the patient, including any contaminants and/or pathogens) out of the enclosure via a fluid port into a container for biohazard processing or disposal. The PRIS may allow positive air pressure therapeutic treatments to be delivered to the patient within the negative pressure environment, and the PRIS may maintain a constant pressure within the interior of the enclosure.

A vehicle component includes a body panel, a flap monolithically connected on an upstream side of the flap with the body panel, the upstream side being defined with respect to an airstream passing the flap when installed in a forward-moving vehicle; and an actuator operatively connected to the flap on a vehicle-inner side of the body panel to move a free downstream end of the flap toward the vehicle-inner side. The flap forms a flush surface with the body panel in a closed state of the flap and reaches an open state by bending of an upstream portion of the flap. The flap and the body panel are made of an elastically bendable material. The flap is formed by a narrow kerf cut machined in the body panel along an outline of the flap that remains attached to the remainder of the body panel on the upstream side.

A windshield wiper system includes a windshield wiper having a wiper blade with a near end and a far end. The windshield wiper is configured for performing a relative rotation of the wiper blade between the far end and the near end of the wiper blade. A mechanism applying a torque to the far end during a sweeping motion of the windshield wiper twists the far end of the wiper blade relative to the near end. The mechanism may perform the relative rotation of the wiper blade regardless of whether the wiper blade is in contact with a windshield. For example, the mechanism may include a stationary cam block having a cam profile, and an actuator arm moving along the cam profile with the sweeping motion of the windshield wiper. The cam profile is suitably shaped to pivot the actuator arm in laterally outer ranges of the sweeping motion.
An edge-morphing arrangement for an airfoil includes a compliant upper surface and a compliant lower surface that are joined together. An actuator is coupled to a driven surface and actuated to move the driven surface and change the shape thereof, with the non-driven surface changing its shape in response to actuation of the driven surface. The upper and lower surfaces can be part of a sub-flap mounted to a traditional flap of the fixed wing of an airplane. The upper and lower surfaces can be mounted to existing structure in the flap, or the flap components can be mounted to the sub-flap. The upper and lower surfaces can alternatively replace the traditional flap in the fixed wing of an aircraft. The upper and lower surfaces are continuous and can be deflected upward, downward, or twisted in a span-wise direction relative to the flap or wing.
A mechanism is hereby disclosed that, when activated in the linear direction of its axis, will expand and contract radially. The novel nature of the device is that of compliant methods and materials used in its design. Compliant members, referred to as dyads, translate the motion and imply resistance in a single structure. Thus eliminating the need for separate members, hinges, pins, springs and the associated assembly. When these compliant dyads are combined in the novel configurations hereby disclosed, a device is created that expands (or contracts) in multiple directions from its primary axis of actuation. Furthermore, one or more actuation dyad sets could be arranged at various angles relative to the global vertical axis. The radial expansion/contraction can be 2D or 3D by adding more primary activation dyad sets. Such a device can be applied to many applications and industries. One such application is for gripping the inside of a tube or object for moving manually or in automation. The compliant nature of this device can be optimized to auto-adapt to the objects size and shape allowing for greater part variation and reduce manufacturing line change-over times. Other applications would include snap fit connections, spherical articulating joints, spinning cutting tools, speed limiting using friction and centrifugal force, braking rotational forces or transmitting it, automatic centering, expanding elastic bands in an assembly process, and stretching an opening for fitment. The design of this device is material friendly and can be made of plastic, composite and metals. It may be of a single monoform construction (created by molding, machining, or additive manufacturing) or made of multiple parts including pivots and different materials to achieve the desired articulation.
