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: An attachment mechanism for using an endoscope with a surgical robot may include a fixture configured to receive a handle of the endoscope such that a longitudinal axis of the handle is oriented parallel with a longitudinal axis of the fixture and an elongate shaft of the endoscope extends distally away from the fixture, and a mounting structure secured to the fixture. The mounting structure is configured to attach the fixture to the surgical robot. The fixture includes a retaining mechanism configured to releasably secure the handle within the fixture. The fixture includes a first motor operably coupled to a first drive mechanism, the first drive mechanism being configured to engage the handle of the endoscope to operate a deflection mechanism of the endoscope.

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.

Abstract: Embodiments of the innovation relate to, in a webserver device, a method for identifying a logic defect in an application. The method comprises establishing a webserver instance of the webserver device with a client device, the webserver instance of the webserver device having a corresponding set of client device permissions; receiving a content request from the client device associated with the webserver instance of the webserver device; detecting a violation of a permission of the set of client device permissions associated with the webserver instance of the webserver device; identifying at least one webserver function associated with the violation of the permission of the set of client device permissions; and displaying a visual identification of the at least one webserver function associated with the violation of the permission of the set of client device permissions.

Abstract: A method of stabilizing Nickel-rich (NMC) cathode materials includes mixing a feedstock of transition metal sulfates, ammonia, and a basic solution to under bubbling of an inert gas to form a reaction solution, precipitating transition metal hydroxide particles from the reaction solution over a first period of time to precipitate the transition metal hydroxide particles therein to form a metal sulfate solution. The method further includes altering the pH of the metal sulfate solution, supplying a Mn-rich feedstock to the metal sulfate solution to form a Mn-rich solution, and precipitating Mn-rich hydroxide nanoparticles from the Mn-rich solution onto surfaces of the transition metal hydroxide particles over a second period of time to form a heterogeneous precursor.

Abstract: Bauxite residue recovery includes mixing a solution of hydrochloric acid (HCL) according to a predetermined concentration, and adding the HCL solution to a quantity of raw red mud recovered from industrial operations as waste material. The highly alkaline property of the bauxite residue, commonly known as red mud is at least partially neutralized from the HCL, and makes the resulting washed red mud more amenable to subsequent uses in various applications in fields such as construction, wastewater treatment, and metal recovery processes. The process recovers washed red mud from the red mud and HCL solution by filtering the raw red mud and HCL solution for generating a stream of leach liquor from the filtrate and the recovered washed red mud from the residue. The neutralized red mud is further treated to extract metals such as calcium, iron, aluminum, silicon, and titanium.

Abstract: A prosthetic device and approach for amputee remediation addresses partial or complete replacement of digits, and leverages the use of the remaining functional digits for directing operation of the prosthetic digits. A complete prosthetic digit replaces an amputated digit from actuated movement driven by an adjacent functional digit. A partial amputation leverages residual movement from the remaining digit portion as input to an actuator for amplifying the intent of the input through a motorized actuator to impart movement to the prosthetic digit. A wrist harness supports the apparatus of partial and complete prosthetic digits as a single appliance. A variable compression feature augments tension on the wrist harness to tightly engage the prosthetic appliance to the wrist to offset a gripping load on the prosthetic digits.
