Abstract: Various implementations include earbud cases with a Hall effect sensor configured to aid in detecting whether the case is open or closed. Certain additional implementations include a holder for a Hall effect sensor in an earbud case. In some particular aspects, a case for a set of earbuds includes: a top section including a set of magnets; and a base section movably coupled with the top section, the base section having: an upper compartment including a set of slots for holding the earbuds; and a lower compartment, having: a printed circuit board (PCB); a holder coupled with the PCB; and a Hall effect sensor coupled with holder, wherein the holder separates the Hall effect sensor from the PCB.

Abstract: A method includes, with a first execution unit of a processor, executing instructions for a processing task on behalf of a first virtual container. The first virtual container is configured to utilize computing resources of the first execution unit without demanding more computing resources than the first execution unit provides. The first execution unit may have exclusive access to a first arithmetic logic unit (ALU). The method further includes, with a second execution unit of the processor, processing instructions for the processing task on behalf of a second virtual container. The second virtual container is configured to utilize computing resources of the first execution unit without demanding more computing resources than the first execution unit provides. The second execution unit may have exclusive access to a second Arithmetic Logic Unit (ALU). The first execution unit and the second execution unit operate in parallel.

Abstract: A riser displacement and cleaning tool assembly (10) comprises a running tool (8) attachable to a work string (11), and a fluid displacing body (1) supported upon the running tool. The fluid displacing body has a head portion (6) provided with an opening (12) to accommodate relative movement of the fluid displacing body with respect to the work string, and also has flexible wiper elements (2) providing dynamic sealing contact with adjacent surfaces of the work string and a riser (20). The fluid displacing body has a skirt (5) depending from the head portion and enclosing a chamber (7) for receiving a fluid. The fluid displacing body is adapted to sealingly engage the riser and the string and is selectively releasable from an initial configuration where the fluid displacing body is supported by the running tool to an operational configuration where the fluid displacing body is axially displaceable from the running tool by introduction of a fluid to the chamber.

Abstract: A loudspeaker suspension structure has an inner circumferential border, and an outer circumferential border, and grooves each extending from the inner circumferential border to the outer circumferential border at an angle with respect to a normal to the inner circumferential border, a profile of a circumferential section of the suspension structure having continuous curvature. Each of the grooves varies from the inner border to the outer border, the variation corresponding to a variation of a principal contour of the suspension structure.

Abstract: A flue cap is provided comprising a body defining a plurality of attachment surfaces adapted for selectively matingly engaging a selected flue from a plurality of different size flues. The flue cap comprises a polymer material defining an attachment surface that is adapted for a close mating engagement with an outer diameter of the selected flue and defines an aperture establishing a passageway in fluid communication with the flue and passing through the cap. A flue assembly is constructed by steps comprising providing an open end of the flue; providing a flue cap comprising a polymer material defining an attachment surface that is adapted for a close mating engagement with an outer diameter of a flue, bonding the flue cap to the flue with an adhesive; and flowing a fluid out the open end of the flue and through the flue cap.

Abstract: A supportive upper body constraint device comprising a base comprising a foam material with a preselected impression load deflection (ILD) ratio for a desired resiliency, and a smooth-surface cover on the base comprising an elastomeric foam material with an ILD ratio less than the base. The device comprises opposing support members on the base, the cover supportingly disposed by the base and support members in a concave contour defining a cavity.

Abstract: A packaged fiber-coupled optical device comprises an alignment housing with a fiber retainer, optical fiber segment(s), and optical component(s) (on substrate(s) with fiber groove(s)). Upon assembly the protruding end(s) of the fiber segment(s) is/are positioned against the fiber retainer, and the fiber groove(s) is/are aligned with the protruding end(s) of the fiber segment(s). The fiber retainer urges the protruding end(s) of the fiber segment(s) into the fiber groove(s). The fiber groove(s) position the protruding end(s) of the optical fiber(s) seated therein for optical coupling with optical component(s). The alignment housing and/or a fiber subassembly may be configured for engaging a mating fiber-optic connector.
