Abstract: An electrohydrodynamic (EHD) drying apparatus includes a non-uniform electric field resulting from an electric field source operable for a high potential, and an electric field source operable for a low potential. A power source is connected to the electric field sources for producing the non uniform electric field for inducing dielectrophoresis (DEP) in an article within the uniform electric field. In particular configurations, the applied non-uniform electric field is for separating a vapor phase being formed during drying from the liquid phase. The electric field source defines a polarizer adapted to produce dielectrophoresis, and the electric field induces coupled electrostatics and momentum for disposing liquid towards the high electric field for drying.

Abstract: A metal-air battery and methods for generating electricity in a metal-air battery are described herein. The battery and the method includes heating an anhydrous salt to obtain a molten salt electrolyte; contacting the molten salt electrolyte to at least one cathode communicating with air; reducing air at the cathode to obtain oxygen ions for diffusing through the molten salt electrolyte; oxidizing at least one metal anode by the oxygen ions in the electrolyte thereby generating electricity and forming a metal anode oxide; and cooling at least one section of the metal-air battery for precipitating the metal anode oxide.

Abstract: A force absorbing device for a footwear appliance includes a shoe upper and a shoe sole having a planar sole surface, such that forces between the shoe upper and planar sole surface in ground contact are absorbed by force mitigation structures disposed in the shoe sole. A footwear article includes a split-sole system that redefines a shoe sole as coplanar surfaces having a force mitigating interface for receiving sudden forces and effectively mitigating these forces by storing kinetic energy and releasing it over time. An elastic field in the force mitigation structure is defined by a resilient material adapted to deform in response to the received force. Frictional engagement between the upper and lower sole may also be augmented by surface characteristics such as dimples, voids and lubricants, in addition to interference engagement with an elastic field.

Abstract: An endoscopic system may include an endoscope including a handle and an elongate shaft extending distally therefrom. The handle may include a non-motorized and non-ratcheting actuation mechanism configured to articulate a distal tip portion of the elongate shaft. The distal tip portion may be articulatable in response to a manually applied force exerted upon the actuation mechanism. Removal of the manually applied force may lock the distal tip portion in its then-current configuration. The non-motorized and non-ratcheting actuation mechanism may include a clutch mechanism actuatable in response to an electrical signal generated in response to sensing a user-applied force to the actuating mechanism by a strain gauge.

Abstract: A recycling and synthesis of charge material for secondary batteries generates single-crystal charge materials for producing batteries with greater charge cycle longevity. Charge material particles undergo a heating for fusing or enhancing grain boundaries between polycrystalline particles. The resulting, more well-defined grain boundaries are easily etched by a relatively weak mineral acid solution. The acid solution removes material at the grain boundaries to separate secondary particles into primary particles along the grain boundaries. The resulting single crystal (monocrystalline) charge material particles are washed and filtered, and typically re-sintered to accommodate any needed lithium (lithium carbonate), and result in a charge material with larger surface area, higher lithium diffusivity and lower cation ordering.
