Abstract: A microfluidic device for evaluation of test subjects for induced neural injury performs testing of multiple test subjects based on uniform and repeatable test stimuli for evaluating neural response for research including traumatic brain injury. A microfluidic device contains multiple test subjects and delivers a consistent, measured test stimuli simulating TBI to each of the test subjects simultaneously. The result is a system to assess neural function, behavior, and neural structure of small animals responsive to sonication-induced traumatic brain injury, to investigate risk and potential recovery. The microfluidic device disposes test subjects at a uniform distance from an injury inducing surface that emits sonication energy to simulate TBI. The uniform distance ensures that each test subject receives the same, controlled injury stimuli, and the test subjects may be evaluated with an attached microscope or video input, or may be extracted from the microfluidic device for further evaluation.

Abstract: An iron anode employs an electrolyte for generating an anode reaction to convert between Iron II and Iron III ions, denoted by Fe(OH)2 and FeOOH, rather than tending towards formation of highly stable Fe3O4, which can tend to cause “dead” regions in the battery. A suitable battery chemistry includes iron-air and other iron metal batteries operable with an aqueous electrolyte and employing oxygen and water cathodes. The iron anode battery employs inexpensive available iron, rather than more expensive and/or volatile materials used in Li-ion and lead-acid batteries. An aqueous electrolyte formed from sodium hydroxide and silicates, optionally with potassium or chloride salts, forms an anode reaction with nanostructured iron oxide particles in a safe and stable battery chemistry which is readily scalable for grid storage.

Abstract: An imaging self-positioning system includes a robotic actuator for manipulating an imaging tool or medical probe and a sensory component for maintaining a normal orientation above patient a treatment site. The imaging tool, typically an US probe, is grasped by an end-effector or similar actuator, and a sensory component engaged with the imaging tool senses an orientation of the tool relative to the treatment surface, and the robotic actuator disposes the imaging tool for maintaining a normal or other predetermined angular alignment with the treatment surface. The treatment surface is a patient epidermal region adjacent an imaged region for identifying anatomical features and surgical targets. A medical probe such as a biopsy needle may accompany the end-effector for movement consistent with the probe, either manually or robotically advanced towards the surgical target.

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 surgical rongeur device has an interchangeable, locking tip at a cutting end for engageable replacement with a variety of cutting tips for facilitating sterilization and blade changes. A detachable linkage between a handle portion and an interchangeable cutting tip (tip) provides a strong connection for actuation by the handle end but allowing for tip replacement via slidable, lateral displacement of the tip. The tip includes a blade and footplate formed from an amorphous metal for longevity and strength advantages. A handle provides a lever to actuate the tip from slidable communication via the detachable linkage. An interlocking member extends longitudinally from the handle into an internal slot on the tip for locking the tip by preventing lateral movement out of alignment with the handle. The aligned tip is responsive to actuation from the handle via a rail for disposing the blade longitudinally against the footplate.

Abstract: A sodium-ion batteries (NIBs) employs doped P2-type phase using novel Na—Mn-Li—O oxide composition with different ions to alleviate the structural deterioration and enhance the electrochemical performance at high voltage. A sodium-ion battery (NIB) exhibits a stoichiometric ratio of sodium, manganese and lithium for a battery cathode, combined and agitated to form a granular mixture in the determined stoichiometric ratio. A doping element is added to the granular mixture, and the granular mixture sintered for a predetermined time and temperature for forming an NIB battery cathode material.

Abstract: A force dissipating device in a footwear appliance includes an actuator responsive to a displacement force from a shoe sole surface, and an elastic field of resilient, compressible material. The elastic field is elongated in a direction aligned with the displacement force, and an inclined surface is attached to the actuator and disposed against the elastic field. The actuator is adapted for movement parallel to the elastic field, while the inclined surface is oriented to compress the elastic field in a direction defined by the inclined surface. The inclined surface is oriented at an angle to compress the elastic field in a direction substantially perpendicular to vertical actuator displacement, thus providing a constant region of opposed, compressive force that is generally constant, rather than increasing with displacement distance.

Abstract: A robotic cutting device includes a cutting tool responsive to a mobile actuator adapted to apply a cutting force in a 3-dimensional (3D) space, and scanning logic configured to identify a cutting path denoted on an article for cutting. Using the cutting path, a mobile actuator is responsive to positioning logic for disposing the cutting tool along the cutting path for performing a prescribed cut on the article. The mobile actuator is a robotic arm responsive to an independent coordinate frame based on a position and orientation of a mobility vehicle supporting the mobile actuator. Cutting is based on traversal of a prescribed path formed from marking or painting optically distinct features. Pixel based analysis reconstructs the path for cutting using a probabilistic evaluation of only the cutting region based on a prediction of path progression, and avoids exhaustive mapping, analysis or reconstruction of the entire article.
