Abstract: Method(s) and system(s) for the direct production of lithium and other metals from a brine solution containing salts of various metal cations at room temperature via a combined sorbent extraction and electrochemical extraction/plating process. This process uses a skeleton structure material that can reversibly insert/extract a desired metal cation to absorb the desired metal ions from a brine solution. The metal impregnated skeleton structure material is then transferred to an electrochemical cell where the metal ions are extracted from the structure and plated in the form of metal onto an electronically conductive substrate. This process is a combination of methods to take metal ions directly from a brine solution to produce an end-product of metal and is a significant improvement over current industrial processes that will reduce the energy required for metal production.

Abstract: The present application is directed towards systems and methods for cluster-based code analysis and transformation. Cluster-based analysis may group code objects based on their similarity across functional areas, such as where a code object is cloned in multiple areas (e.g. sort functions that are duplicated across areas, or reports or tables that are identical). In some implementations, objects may be grouped into clusters by type, or based on reading from or writing to a common table. In some implementations, clustering at different layers may be possible.

Abstract: Architectures and techniques are presented that can facilitate improved design and function of certain heating, ventilation, and air conditioning (HVAC) devices. Architectures directed to an improved evase device can be designed with rounded corners that can facilitate, e.g., mitigation of reverse flow that traditionally grows back from corners of a transition from an axial fan to a rectangular duct. Architectures directed to an improved intake device can be designed to limit intake from certain flow directions and to smoothly change flow direction, which can facilitate, e.g., reduction in noise. Architectures directed to an improved fan intake device can be designed to reduce noise without significantly reducing total pressure. Architectures directed to an improved air handler device can be designed to concurrently heat and cool air and to reduce dimensions (e.g., size, weight) that can reduce costs and mitigate shipping and installation difficulties.
