Abstract: The present disclosure relates to an airfoil assembly for a turbine engine and methods of assembly thereof. The airfoil assembly generally includes a composite airfoil and a spar. The composite airfoil has a pressure side and a suction side extending in an axial direction between a leading edge and a trailing edge defining a chordwise direction and extending radially between a root and a tip defining a spanwise direction and having a span-length. The spar includes a first portion including a first material and a second portion joined at an interface with the first portion. The second portion further includes a second material, different from the first material, joined to the first portion at an interface. The method generally includes joining the first portion with the second portion at the interface; and assembling the spar with the composite airfoil.

Abstract: Systems and methods for generating a personalized lobby interface based on contest attributes and user attributes for one or more users of a contest management system. The contest management system can generate, execute and maintain a plurality of contests, such as but not limited to, fantasy sports contests. Further, the contest management system can maintain a plurality of user profiles with each of the user profiles associated with at least one user. To provide content and/or recommendations to one or user profiles, the contest management system can create one or more personalized lobbies for each of the user profiles. The personalized lobbies can display one or more contests selected by the contest management system that a user associated with the respective user profile may be interested in based in part on their respective profile attributes and/or contest history.

Abstract: Disclosed herein are systems and methods for interacting with a consumer ledger. The systems and methods include: receiving a copy of the consumer ledger from one of a plurality of miners; adding a transaction to the consumer ledger; and transmitting the consumer ledger to the plurality of miners for conformation.

Abstract: Apparatus and methods for sensing resonant circuit signals to enhance control in a resonant converter are described herein. A buffer circuit coupled in parallel with or across a resonant component (e.g., a transformer) input port avails a buffered primary port signal for use in resonant conversion. The buffered primary port signal is a comprehensive signal including information relating to both input voltage and input power; and it may be used to advantageously enhance switching and power conversion in an inductor-inductor capacitor (LLC) converter. Additionally, the LLC converter uses a sense interface circuit to provide a scaled replica of the buffered primary port signal. In one example the scaled replica can advantageously be used with a secondary side controller to control output power based on the comprehensive information contained within the buffered primary port signal.

Abstract: A system for treating various medical conditions in humans includes a medical or therapeutic laser operating at wavelengths in the near infrared range of between 1250 nm-1267 nm, with a target wavelength of 1260 nm, at power levels between 2 Watts and 60 Watts, and for a period not to exceed 60 seconds per dose. The emitted laser light energizes, e.g., the stem cell niche or mitochondria of the human tissue to which it is applied, both directly and indirectly via activation of cell signaling intermediaries including but not limited to heat shock proteins, thereby stimulating cell activity to promote healing and reduce pain. In this specific wavelength range, water absorption of the laser light energy is plateaued which effectively acts as a conduit allowing the laser light energy to be transferred deeper into the tissue without causing thermal damage to the skin and tissue.

Abstract: The present disclosure relates to polymorphs of D9-THC-naphthoylester for the preparation of D9-Tetrahydrocannabinol in high yields and high purity, methods of preparing the D9-Tetrahydrocannabinol, and compositions comprising the D9-Tetrahydrocannabinol.

Abstract: A method for delivering one or more oral care active agents to a mammal's mouth using a nonwoven web of filaments and/or fibers containing one or more oral care active agents that are releasable from the filaments and/or fibers is provided.

Abstract: A detergent product containing one or more active agents is provided.

Abstract: The present disclosure is directed to an improved metalworking lubricant monitoring, logging, recording, calculating, analyzing, alerting and reporting apparatus, system and method that monitors data and changes to the lubricant application process and the amount and concentration of lubricant being dispensed or delivered, analyzes, calculates and records data and changes or alterations to the amount dispensed, and alerts or reports the data and changes in real-time, when necessary, over various communication channels, to those responsible for overseeing the system changes.

Abstract: An oral product includes a body that is wholly receivable in an oral cavity. The body includes a mouth-soluble polymer matrix, cellulosic fibers embedded in the mouth-soluble polymer matrix, and nicotine or a derivative thereof dispersed in the mouth-soluble polymer matrix. The oral product is adapted to release the nicotine or a derivative thereof from the body when the body is received within the oral cavity and exposed to saliva.

Abstract: A wall mount for a tool box includes a base, the base being at least substantially planar and defining a volume dimensioned to receive a tool box, at least one support extending outwardly from a lower portion of the base, the at least one support constructed to at least substantially bear a weight of a tool box received by the wall mount, and at least one receiver extending outwardly from an upper portion of the base, the at least one receiver being constructed to engage a correspondingly dimensioned and positioned feature of a tool box to prevent outward rotation of a tool box about the at least one support.

Abstract: A compound helicopter includes a fuselage including a fuselage airframe, a translational thrust system coupled to the fuselage airframe and a pylon assembly subject to vibration. The pylon assembly includes a transmission and a rotor system having a main rotor assembly. The compound helicopter also includes a main rotor vibration isolation system including a plurality of augmented liquid inertia vibration eliminator units each having an isolation frequency and each coupled between the fuselage airframe and the pylon assembly to reduce transmission of the pylon assembly vibration to the fuselage airframe at the isolation frequency.
