Abstract: Disclosed herein are new therapeutic methods comprising administering compounds that can stabilize HIF and inhibit HIF prolyl hydroxylase (HIF-PH). In particular, methods described herein can be useful for treating/preventing a disease or condition in patients in need thereof, such as a patient having a viral infection such as a respiratory and/or pulmonary viral infection (e.g., an infection such as COVID-19 or a coronavirus infection). Methods described herein can also be useful for treating/preventing organ injury (e.g. organ injury that occurs concurrently or as a result of an infection). For example, methods described herein can be useful for treating or preventing acute lung injury, acute respiratory distress syndrome (ARDS), cardiovascular injury, injury to the liver, kidney diseases, and/or multi-organ failure.

Abstract: A hydraulic fluid control valve (HFCV) configured to recirculate an exiting hydraulic fluid from a first hydraulic actuation chamber to a second hydraulic actuation chamber is provided. The HFCV includes a selectively movable spool having an outer annulus configured to receive and deliver the exiting hydraulic fluid to one or both of either a sump or one of the first or second hydraulic actuation chambers.

Abstract: A cam phaser is described for selectively engaging in a torque transmitting mode or an angle control mode. In the torque transmitting mode, torque from a camshaft is transmitted to an e-motor, which functions as a generator and provides electrical energy.

Abstract: Braces having elastic portions that can be made effectively inelastic, based on a level of comfort or support desired by a user, via an inelastic tightening mechanism are disclosed. Some contemplated braces have lumbar supports that are at made at least in part of an elastic material, and inelastic tightening systems that extend across the elastic material and can decrease the effective elasticity of the elastic material to provide greater support.

In addition, the operations may include communicating the first device audio to the second second-end device as second session audio of the second communication session.

Abstract: A brace comprises a belt and removably attachable vertical strut(s). Each vertical strut can comprise one or more of a strut(s), thoracic pad(s), hip pad(s), lumbar support pad(s), chest support pad(s), de-rotation pad(s), or any other component suitable to assist or restrict movement of a wearer's body, reduce or apply a force to a wearer's body, correct the shape of a wearer's body, reduce pain, or provide support to a wearer's body. It is contemplated that each component can be removable or adjustable from a vertical strut or belt.

Abstract: Lower back braces and materials for braces having an elastic base and inelastic strands or tightening mechanism(s) are provided. An elastic base material could be made effectively inelastic by tightening an inelastic cord that extends across the elastic base material. Additionally or alternatively, an elastic base material could include one or more inelastic strands that define one or more inelastic compression zones in an otherwise elastic base.

Abstract: A central valve for a camshaft phaser includes a hollow cylindrical housing, a hydraulic unit, a control piston, a retaining ring, and a washer. The hollow cylindrical housing includes a first radial opening and a groove. The hydraulic unit is disposed in the hollow cylindrical housing and includes a second radial opening and a channel. The control piston is axially moveable in the hydraulic unit to adjust a flow of a hydraulic medium through the first radial opening, the second radial opening, and the channel. The retaining ring is disposed in the groove to retain the hydraulic unit and the control piston in the hollow cylindrical housing. The washer is disposed in the hollow cylindrical housing axially between the hydraulic unit and the retaining ring.

Abstract: A camshaft phaser arrangement configured for a concentric camshaft assembly having inner and outer camshafts is provided. The camshaft phaser arrangement includes a first camshaft phaser, a second camshaft phaser, and a coupling that non-rotatably connects the first camshaft phaser to the concentric camshaft assembly. Each of the camshaft phasers is configured to be connected to either the inner or the outer camshaft. The coupling accommodates for radial and axial offset between the first camshaft phaser and the second camshaft phaser.

Abstract: A camshaft phaser assembly is disclosed. A trigger wheel is provided that includes a position indicator and a first toothing. An input gear includes a second toothing. An output gear is adapted to drive a camshaft, and defines a third toothing. The first toothing and the third toothing have an identical profile. A connection assembly includes a fourth toothing engaged with the first toothing, the second toothing, and the third toothing, such that an input provided by the input gear is transmitted to both the output gear and the trigger wheel, and the trigger wheel and the output gear are driven in unison. A method of detecting a position of a camshaft based on a trigger wheel is also disclosed.
