Abstract: A manufactured component, such as headgear or a headgear strap, for a patient interface for delivery of pressurised air or breathable gas to an entrance of a patient's airways may include a textile portion having a first material with a first melting point. It may also include a plastic portion over-moulded to the textile portion. The plastic portion may be formed of a second material having a second melting point. The melting points may be different such that the second melting point is chosen to be less than the first melting point of the first material. The component may be moulded in a multi-step process that moulds separate portions of the plastic portion and the textile portion at different times. The resulting plastic portion may then have a mechanical bond with the textile and may do so without significant chemical bonding between the plastic portion and the textile.

Abstract: A portable inflatable diving float that includes an inflatable float body is revealed. The float body consists of a horizontal portion provided with a left folding area formed on the left side and a right folding area formed on the right side. After the left and the right folding area being folded to a middle portion of the float body, a left edge portion of the left folding area and a right edge portion of the right folding area are connected by a first connection member and kept in the folded state. A flat body formed after deflation of the float body becomes a backpack body with smaller area. At least one strap member is connected between the top end and the bottom end on a front side or a back side of the float body so that users can carry the backpack body on their back.

The auxiliary shower spray conduit is oriented in a serpentine shape and has a plurality of a spray hose that are aligned with a corresponding plurality of jet apertures defined through a surface of an upper mat.

Abstract: A seal head assembly includes a plurality of heat seal plates defining a corresponding plurality of heating areas, each heat seal plate including a heating element to independently control the temperature of the corresponding heating area.

Abstract: A mask system includes a frame defining a breathing chamber, a cushion provided to the frame and adapted to form a seal with the patient's face, and a shroud provided to the frame and adapted to attach headgear. The shroud includes a retaining mechanism structured to connect the shroud to the frame. The retaining mechanism includes both a taper lock arrangement and a retaining clip arrangement.

Abstract: The present invention provides a sealing closure made of flexible magnetic strips with a non-uniform thickness, which provide an improved interlocked seal in addition to a magnetic seal. The sealing closure has strips with at least one guide that aligns automatically with another strip when the two strips are brought together to create a more secure sealing closure.

Abstract: A recording device captures information and stores the information in a data store as a data record. The recording device includes a low-power wireless interface and a high-power wireless interface. A network device includes a low-power wireless interface and a high-power wireless interface. An activation device transmits a data notification and a network notification. Upon receiving the data notification, the network device activates its high-power wireless interface. Upon receiving the network notification, the recording device activates its high-power wireless interface. The recording device transmits the data record to the network device via its high-power wireless interface.

Abstract: A method of processing a charging information of a vehicle and system of processing a vehicle charging information comprises a user terminal transmitting a vehicle information to a cloud server; the cloud server obtaining a charging information of the vehicle; the cloud server transmitting a reward information corresponding to the vehicle identity information to the user terminal based on the state information of the vehicle, the information comprising the charging information; and the user terminal displaying the reward information.

Abstract: A ladder pad includes an elongated body that defines a slot extending along a length of the elongated body. The elongated body further defines a plurality of openings. The openings are spaced along the length of the elongated body. The slot of the elongated body is sized for receipt of a rail of a ladder and/or an edge of a gutter. Each of the openings is sized and positioned for receipt of a respective rung of the ladder and/or a standoff bracket of the gutter.

Abstract: The disclosed system receives a first indication that a first medication is available for delivery to a first location within a healthcare facility, and identifies a preparation status of a second medication. Based on the delivery time and the completion time for the second medication, the system determines whether the first medication should be delivered prior to completing the preparation of the second medication and, when determining that the first medication should not be delivered prior to completing the preparation of the second medication, a notification to wait for the preparation of the second medication before delivering the first medication is sent to a display device associated with a delivery person.

Abstract: Techniques herein store database blocks (DBBs) in byte-addressable persistent memory (PMEM) and prevent tearing without deadlocking or waiting. In an embodiment, a computer hosts a DBMS. A reader process of the DBMS obtains, without locking and from metadata in PMEM, a first memory address for directly accessing a current version, which is a particular version, of a DBB in PMEM. Concurrently and without locking: a) the reader process reads the particular version of the DBB in PMEM, and b) a writer process of the DBMS replaces, in the metadata in PMEM, the first memory address with a second memory address for directly accessing a new version of the DBB in PMEM. In an embodiment, a computer performs without locking: a) storing, in PMEM, a DBB, b) copying into volatile memory, or reading, an image of the DBB, and c) detecting whether the image of the DBB is torn.

The patient interface system further includes headgear with a back portion and a pair of upper headgear straps extending from the back portion. In addition, a shroud is removably mounted on the frame and includes a pair of upper headgear connectors configured to connect to the pair of upper headgear straps. Each of the pair of upper headgear connectors comprises a rigidizer configured to be proximal to a nasal bridge region of the patient when donned by the patient. The pair of upper headgear straps are configured to be releasably attached to the pair of upper headgear connectors such that, when donned by the patient, the pair of upper headgear straps extend substantially parallel to the patient's Frankfort horizontal plane.
