The invention may also comprise an attachment mechanism to attach to or anchor the patient interface.

Abstract: A power supply system is operable to harvest power at low and high line currents. A current transformer is arranged to couple to a power transmission line. A current sensor which may be a Rogowski coil is arranged to couple to the power transmission line. Branches of power supply circuitry are connected to a plurality of secondary windings of the current transformer. A control circuit selects one of the branches of power supply circuitry, depending on sensed magnitude of line current, to provide electrical power to an output capacitor. Sufficient stored energy is also provided for performing a backup of operating parameters when the line current reduces to zero.

Abstract: Embodiments of the present disclosure pertain to electrodes for energy storage devices. The electrodes include a substrate from which extends bundles of carbon nanotubes. A metal, such as lithium, infiltrates the bundles, between the carbon nanotubes, to coat the surfaces of the carbon nanotubes. The bundled, metal-coated carbon nanotubes are covered with a layer of solid-electrolyte interphase that can be formed before the metal is inserted into the bundles by pretreating the bundles with an electrolyte bearing ions of the metal.

Abstract: A diffuser for use with a wound retractor and configured to deliver gases includes an interface tube for connecting to a gases supply and a diffuser interface positioned at a proximal end of the interface tube, the diffuser interface configured for delivering gases received from the gases supply through the interface tube, and the diffuser interface comprising a diffusion mechanism configured to deliver gases in a diffusion direction. A wound retractor with an integrated diffuser is also disclosed. The wound retractor includes an upper ring, a lower ring, a sleeve extending between and connecting the upper ring to the lower ring, and an integrated diffuser interface having a gases inlet and a diffusion mechanism.

Abstract: A server accesses vehicle data from each connected vehicle (CV) of a subset of a plurality of CVs on a roadway portion, the vehicle data comprising at least one of: a position, a velocity, or a headway. The server generates, based on the accessed vehicle data, a long-term shared world model. The server generates, using the long-term shared world model, a data structure representing predicted future velocities on the roadway portion by position and time by applying a traffic flow model to the long-term shared world model. The server transmits, to a connected autonomous vehicle (CAV), a control signal for controlling operation of the CAV based on the generated data structure.

Abstract: Described are active materials for storing metal cations, such as lithium ions, in a cathode of an electrochemical cell. The active materials comprise an ordered mixture of sulfurized carbon (SC) particles, smaller ionically conductive particles, and still smaller electrically conductive particles. In comparison with a random mixture, where SC particles are mixed with particles of another material, the ordered mixture creates discrete, solid composition of more than one type of guest particles on the perimeter of SC host particles for ionic and electronic conduction to and from the SC host particles.

Abstract: Processes herein may be used to thermally crack various hydrocarbon feeds, and may eliminate the refinery altogether while making the crude to chemicals process very flexible in terms of crude. In embodiments herein, crude is progressively separated into at least light and heavy fractions. Depending on the quality of the light and heavy fractions, these are routed to one of three upgrading operations, including a fixed bed hydroconversion unit, a fluidized catalytic conversion unit, or a residue hydrocracking unit that may utilize an ebullated bed reactor. Products from the upgrading operations may be used as feed to a steam cracker.

Abstract: A computer-implemented method for computing or modeling the risk of a cyber security breach to an asset begins by gathering coverage information from network sensors, endpoint agents, and decoys related to the asset, as well as gathering importance information related to the asset, alerts and anomalies from an enterprise and vulnerability information related to the asset. From this, a threat-score is computed for the asset. Connections or coupling information is gathered between users and assets, users and data, and assets and data, which is fused to generate a 3-dimensional vector representation of coverage, importance, and threat-score of the assets, users and data. From this 3-dimensional vector, an asset risk score is computed to provide the asset risk score.
