Abstract: A system, apparatus and methods are provided for supplying gases to a user. The supply includes a sub-therapeutic mode and a pressure support mode for delivering therapy to a user. A flow diversion device or valve switches from a first mode corresponding with the sub-therapeutic mode of the system to a second mode corresponding with the pressure support mode of the system. In the first mode, the valve opens a larger flow path between the interior of the user interface and ambient air than in the second mode.

Abstract: In accordance with one aspect the present invention may comprise a regenerative blower comprising: a housing, a first port and second port in the housing, an airflow channel extending between the first and second ports for airflow between the ports, an impeller rotatable in an impeller channel to promote airflow in the airflow channel from the first port to the second port, a motor to drive the impeller, and an interrupter between the first and second ports to limit airflow from the second port to the first port.

Abstract: Data related to the adherence of a patient to a therapy regime can be collected from multiple medical devices, each of which may have an incomplete data set with data entries associated with times. Each incomplete data set represents a portion of a complete data set. The data sets can be integrated to create a complete data set with data entries from each incomplete data set being arranged in a temporal sequence with respect to one another. A report may be generated, the report having the data entries of the complete data set or a function of the data entries of the complete data set.

Abstract: A patient interface comprises a blower, a cushion for contacting a user's face, and a mask body and/or a frame for supporting the cushion on a user's face. The cushion and/or the mask body or frame define an interior space for receiving a flow of gases from the blower. The blower is mounted to the mask body or frame so that the blower is at least partially within the mask body or frame. The blower substantially separates a high pressure side of the mask body or frame from a low pressure side of the mask body or frame and/or the mask body or frame is substantially without a wall between the blower and the interior space.

Abstract: Aspects of the present disclosed technology relate to drop balls and covers for drop balls for use with settable downhole tools. Aspects of the present disclosed technology also relate to methods for using such drop balls and covers with settable downhole tools to selectively allow fluid to pass through such downhole tools, or to block fluid flow through the settable downhole tool.

Abstract: The invention relates to a non-heated humidification device comprising a wick; a chamber for holding water in contact with the wick; and a gas inlet to the chamber, wherein the chamber and wick are configured to humidify gas passing through or over the wick at ambient conditions. The device may be modular and attachable to a flow generator. The device may comprise dual gas circuits and a control system for controlling the gas flow through the gas circuits in order to control the humidity of the gas output.

Abstract: A downhole tool is configured on a wireline adapter kit in the run-in position is disclosed. The downhole tool comprises a large open bore when the downhole tool is set and the wireline adapter kit is removed, thereby allowing production to commence without removal of the downhole tool. The large bore diameter may be greater than 2 inches for a 4.5 inch casing, or greater than 2.5 inches for a 5.5 inch casing.

Abstract: A filament-reinforced composite material having with load-aligned filament windings enables improvement of mechanical properties for specific loading of parts made from the material. The orientation of the winding within the part may be changed depending on an orientation of an external load to the part. In one example, the part may be a slip in a frac plug or a bridge plug in a downhole application.

Abstract: Apparatus and methods are disclosed for controlling pressure delivery to a user such as a patient. A flow generator generates an outlet flow at an outlet port for delivery to a patient. At least one sensor measures properties of the flow of gas at the outlet port or being delivered to the patient. A controller is operatively connected to the flow generator and the at least one sensor, and is adapted to operate according to a pressure control mode in which the controller controls the flow generator to output a substantially steady pressure or a flow control mode in which the controller controls the flow generator to output a substantially steady flow. The controller operates in the flow control mode when a patient may be awake and in the pressure control mode when the patient may be asleep.
