Abstract: An aerodynamic flow control system includes a plurality of actuator units integrated at predetermined locations along a span of an aerodynamic surface of a vehicle to provide aerodynamic active air flow control, wherein each of the plurality of actuator units includes an electrically powered compressor to compress air; a transitional component to receive the compressed air from the compressor and provide two streams of the compressed air; and a fluidic oscillator having two inlet ports that receive the two streams of the compressed air, and an exit port that discharges a single oscillating flow of air at a predetermined velocity.

Abstract: A multi-layer pre-drape apparatus is applied to a patient before the patient is moved into the operating room. The multi-layer pre-drape apparatus includes a lower layer with a center aperture and an upper layer that covers the aperture. The multi-layer pre-drape apparatus can be placed on a sterilized area of the patient to maintain the cleanliness of the incision area. Alternatively, the multi-layer pre-drape apparatus can be placed on the patient and sterilization fluid can be applied to the skin of the patient through the aperture. The patient can then be moved into the operating room and the upper layer of the multi-layer pre-drape can be removed to expose the sterilized area of the patient in the aperture. Additional drapes can be added to the pre-drape apparatus.

Abstract: Systems, devices and methods to improve safety and efficiency in an operating room comprise providing a suture package that holds new suture needles and needle receptacles for storing used needles. The devices can be safely worn for the surgeon to self-dispense new suture needles in the near surgical field and to secure the used needles into a needle trap or a needle retainer located on his extremity, on his operative instruments or on the surgical drapes. The device may provide automated and/or simplified needle counting both during use and after removal from the surgical field. The device may be configured for ergonomic and efficient use so as to minimize the actions and motions of the surgeon to dispense and secure the needle.

Abstract: Provided herein are methods for the modulation of appearance or material properties within items of apparel or equipment. Also provided herein are design articles having alterable designs. Generally, such design articles comprise (1) a microfluidic circuit, and (2) an inlet and an outlet, the alterable design capable of being modulated through use of a docking system to deliver fluid to the microfluidic circuit.

Abstract: An electrochemical cell system for generating electrical power is disclosed. The electrochemical cell system comprises a plurality of fluidly connected electrochemical cells. Each electrochemical cell comprises an anode and a cathode. The anode is configured to permit a fluid comprising at least an electrolyte to flow in contact therewith to oxidize a fuel. The cathode is permeable to an oxidizer and is configured to receive electrons to reduce the oxidizer. The cathode and the anode are spaced apart to define a gap therebetween for receiving the fluid flow. The plurality of electrochemical cells are connected in fluid flow series such that, for each pair of fluidly connected electrochemical cells, the fluid flows from a first cell of the pair of cells to a second cell of the pair of cells.

Abstract: An oxygen recovery system configured to recover evolved oxygen from a regenerative electrochemical cell. The electrochemical cell includes an oxygen reduction cathode, a fuel electrode configured to be a fuel anode when the cell is operated to generate electricity and a cathode for reducing fuel thereon when the cell is operated to regenerate the fuel, and an oxygen evolution anode that is configured to evolve oxygen from an electrolyte solution when the cell is operated to regenerate the fuel. The oxygen recovery system includes an oxygen separator located downstream of the oxygen evolution anode in a recharge direction of flow. The oxygen separator is configured to separate the evolved oxygen from the electrolyte solution. An oxygen recovery path is disposed between the oxygen separator and the oxygen reduction cathode. The oxygen recovery path is configured to direct the evolved oxygen separated from the electrolyte solution to the oxygen reduction cathode.
