Abstract: A headset includes a thermal frame disposed within a housing. A printed circuit board (PCB) is thermally coupled to the thermal frame. Heat generated by one or more electrical components on the PCB is transmitted to the thermal frame, which distributes the heat uniformly throughout the headset. A first heat pipe is disposed on a first side of the PCB in contact with at least a portion of the thermal frame, the PCB, and/or an electrical component disposed on the PCB to draw heat from the electrical component, and a second heat pipe is disposed proximate a second side of the PCB and is configured to draw heat from second side of the PCB.

Abstract: A headset includes a thermal frame disposed within a housing. A printed circuit board is thermally coupled to the thermal frame. Heat generated by one or more electrical components on the PCB is transmitted to the thermal frame, which distributes the heat uniformly throughout the headset. The thermal frame provides a substantially rigid structural support to which components are coupled and is configured to transfer thermal energy away from the one or more electrical components of the headset and toward an environment located outside of the housing.

Abstract: A nanocomposite includes one or more graphene-based materials (GMs), a nitrogen-containing polymer (an N-polymer), and elemental sulfur (S). The nanocomposite is suitable for use as a stable, high capacity electrode for rechargeable batteries such as lithium-sulfur (Li—S) batteries. Example methods of fabricating a nanocomposite include the addition of an N-polymer to a dispersion (e.g., an aqueous dispersion) or slurry of GMs mixed with a sulfur sol. The N-polymer can interact strongly with the GMs to form a cross-linked network. In one embodiment, hydrothermal treatment of the aqueous dispersion or slurry is used to melt the sulfur such that it becomes distributed within the network formed by the GMs and the N-polymer. The resulting nanocomposite material can then be processed through the addition of one or more other binders and/or solvents, and formed into a final electrode.

Abstract: According to techniques of this application, a garment may include a trunk, three left sleeves, and three right sleeves. Two of the left sleeves and two of the right sleeves may be short sleeves. The third left sleeve and the third right sleeve may be long sleeves. The garment may include a placket that comprises a first placket piece, a second placket piece, and a third placket piece portion. The placket may be assembled separately and then attached to a V-neck cutaway of the trunk.

Abstract: Provided is an abatement device that reduces an amount of drainage of circulating water. The abatement device lowers an average drainage flow of circulating water to a low flow, when a ratio of a concentration of silicon dioxide within the circulating water and a concentration of hydrogen fluoride within the circulating water is greater than or equal to a predetermined value at which hydrofluorosilicic acid can be produced, and raises the average drainage flow of the circulating water to a high flow higher than the low flow, when the ratio of the concentration of silicon dioxide within the circulating water and the concentration of hydrogen fluoride within the circulating water is less than the predetermined value.

Abstract: A filter screen assembly is shown for filtering drilling mud used during oil and gas well drilling operations. The filter screen assembly is installed at the surface of a well on the discharge side of the mud pump at ground level. The filter screen assembly is installed upstream of the rig swivel, rotary hose and Kelly and downstream of the discharge from the mud pump. Since it is located at ground level, it does not pose the safely hazard associated with elevated components. It does not need to be removed and reinstalled when additional segments are added to the drill string and is always easily accessible for routine maintenance or replacement.

Abstract: The lower end assembly of a measurement while drilling tool is secured against shock and vibration while drilling through the use of a locking cuff, an abrasion ring and a locking nut. A mule shoe at a lower end of the assembly has a diameter sized to allow a pulser helix to pass. The locking cuff is installed on one end of the mule shoe. A poppet housing is attached to an end of the pulser helix opposite the mule shoe. An abrasion ring is received about the external diameter of the pulser helix and is received on a shoulder located between the pulser helix and the poppet housing. An externally threaded lower end of the locking nut is received within a mating threaded bore in the extended locking cuff so that a portion of the locking nut is located between the locking cuff and the poppet housing. Tightening the locking nut within the bore of the locking cuff acts to lock the lower end assembly with respect to the mule shoe.
