The ventilation interface for sleep apnea therapy interfaces a ventilation device to the patient's airways. The ventilation interface includes a pair of nasal inserts made from flexible, resilient silicone which are oval shaped in cross-section and slightly tapered from a base proximal the ventilation supply to the distal tip end. A bead flange is disposed about the exterior of each insert at the distal end of the insert. A bleed port for release of exhaled air is defined through a conical vent projecting normally to the path of the incoming air flow, and continues through a nipple extending to the exterior of the air conduit. In one embodiment, a pair of nasal inserts are integral with a nasal cannula body, with bleed ports axially aligned with each insert. In another embodiment, each insert is independently connected to a separate, thin-walled, flexible supply line.

A high-efficiency air handler that is suitable for moving large volumes of air. The air handler comprises a coil and a fan. The total air volume moving through the unit is preferably over about 2000 CFM, with a total fan static pressure rise of less than about 0.5 inches and preferably less than 0.2 inches of water. The fan is preferably a modified ceiling fan with a rotational speed of less than about 450 rpm. The air handler is preferably part of a system where dehumidification and sensible cooling functions are separate. The separate dehumidification allows for much higher supply air temperatures, preferably within about 10° F. of the space temperature. Low-velocity air distribution through a ceiling plenum or a vent into the space allows for very low fan static pressures, which greatly reduces fan energy use compared to conventional ducted systems. The low static pressures and high supply-air temperatures allow the use of existing drop ceiling construction with little modification. The system can also include low-cost thermal storage. Latent thermal storage is in the form of a concentrated liquid desiccant solution. Chilled water storage is another option. The result is a major improvement in energy efficiency and comfort while reducing installed cost and peak electrical demand of the system.

The hearing device comprises an ear-piece (1) which is designed to be worn at least partially in an ear canal of a user of the hearing device.

The vent extension (4) is a protrusion extending the vent passage (3) beyond the body (2) of the ear-piece (1). The vent extension (4) is adapted for abutting on a surface of the body of the user and is thereby inconspicuous and / or contributes thereby to retention. A method for manufacturing such a hearing device is also disclosed.

An apparatus to ventilate attic space of a structure such as a home or building is provided. The apparatus includes a flexible air sealer and a fan housing unit. The apparatus is connected to trusses or rafters of the structure. The apparatus is placed directly below a roof vent, with the air sealer creating a seal between the fan housing and the roof vent. The air sealer supports propeller fans located in the fan housing. The airflow caused by the fan directs air into the flexible air sealer, through the openings of the roof vent, and out of the attic space. The apparatus may further include adjustable truss connectors that are removably attached to the air sealer and the trusses to allow the apparatus to be installed between variably spaced rafters.

Intumescent may or may not be included on the angle piece.

Improvements are disclosed in surge reduction tools for running in casings or casing liners downhole with the ability to restore circulation in the event a tight hole condition is encountered. The improved tool includes among other features 1.) an axial indexing apparatus which allows the valving sleeve to be moved downward in predetermined increments to allow alternate closing and opening of the vent ports, 2.) a camming sleeve and Bellville spring washers which provide the surge reduction tool with a more predictable release pressure than has heretofore been available, 3.) a dart directing sleeve which has a smaller, smoother bore than the drill string and provides the important function of aligning the dart before it lands in the seat so that the dart resistance when passing through the seat is minimized, and 4.) chevron seals arranged in the housing above and below the vent port which reduces the potential for hydraulic lock and provides a seal mechanism that is more reliable while running in downhole conditions.

A roof vent construction which is comprised of an assembly including a cowl, a base, and a cowl retaining member. These elements provide a structure which provides cover for rain and discourages rain from entering the vent underneath the cowl, but nevertheless allows for suitable ventilation as needed. In one embodiment a configuration is used in which an external baffle is used which air passes before passing underneath a cowl. Once the air is passed underneath the cowl, the air then passes over one and one configuration two internal baffles before the air passes out of a pair of vent cavities defined by the base. In a second configuration, a cowl extends substantially to the leading edge of the construction. Air flows underneath the leading edge of the cowl and then passes over a large internal baffle, over a first small internal baffle, and finally over a second small internal baffle before passing through the vent cavities and out of the structure. Another invention relates to the use of two surface portions on the vent assembly, one surface portion configured to match a first course of tiles and the other surface portion configured to match a second course of tiles adjacent to said first course of tiles.

Certain aspects and embodiments of the present invention provide an airbag having a vent that can adaptively release gas from the airbag upon impact with an occupant. The vent may include a membrane and / or diaphragm that can control the amount of gas released from the airbag based on the pressure in the airbag.
