A method of treating a constricted sinus passageway of a patient includes traversing the canine fossa region of the patient so as to form a passageway in the sinus cavity. A cannula is positioned in the passageway. A visualization tool such as an endoscope is passed through a lumen or channel in the cannula to aid in visualization of the anatomical site of interest. A balloon dilation catheter is then deployed through or along the cannula so as to place the balloon within or across the constricted anatomical space (e.g., ostium). The balloon is then expanded so as to expand at least a portion of the constricted anatomical space. Alternative embodiments include the use of an optional guide wire and incorporating a endoscope lumen through the balloon dilation catheter.

An apparatus (10) maintains a desired distance between two parts (5, 6) of a severed sternum of a patient. The apparatus (10) includes an elongate member (20), such as a plastic or surgical steel plate, and an element (60) for securing the elongate member (20) to each of the two parts (5, 6) of the severed sternum. The elongate member (20) has longitudinal edges (32, 34) dimensioned and configured to space apart the two parts (5, 6) of the severed sternum the desired distance. When implanted, the two parts (5, 6) of the severed sternum engage the longitudinal edges (32, 34) of the elongate member (20) to maintain the desired distance between such parts.

An exhaust heat exchanger includes a water tank accommodating tubes and having an outside space defined outside of the tubes, a gas tank having an exhaust passage and an outside space defined outside of the exhaust passage, a dividing portion to separate the outside space of the water tank from the exhaust passage of the gas tank, and a communication portion. The outside space of the gas tank and the outside space of the water tank communicate with each other through the communication portion.

By using the structure, the movement space of the mechanism is greatly enlarged, and the rigidity of the mechanism is increased, thereby lowering the requirements for the initial pose of the robot.

Kits designed to stimulate creativity, to provide exercise for fine motor skills, and to improve spatial perception. The kits may be useful as a stimulating “toy” for children to develop creativity, spatial perception and motor skills, as a therapeutic kit for the elderly or those requiring rehabilitation of fine motor skills; as a diversion to relieve stress, to create unique works for the home or office, to display photos and memorabilia, and for a host of other purposes, limited by the imagination. The kits include at least shaped components, fasteners, and a platform onto which a three-dimensional work is mounted.

An electric re-heat dehumidification apparatus to dehumidify a conditioned space is provided and includes a conditioning unit to produce an output airstream including overcooled air to be provided to the conditioned space to overcool the conditioned space during the dehumidifying of the conditioned space, a resistive element disposed within an output airstream of the conditioning unit, which, when activated, heats the overcooled air of the output airstream and a controller, operably coupled to the resistive element, to activate the resistive element in accordance with information of the conditioning unit, the resistive element and a temperature of the conditioned space to limit the overcooling of the conditioned space.

A turbine cooling system is provided, having a compressor for supplying cooling air, a forward turbine rotor wheel space, a high-pressure packing seal (HPPS) bypass cavity, and a metering device. The forward turbine rotor wheel space is cooled by the cooling air supplied by the compressor. The HPPS bypass cavity is in fluid communication with and receives a portion of the cooling air from the compressor, and is in fluid communication with and supplies the cooling air to the forward turbine rotor wheel space. The metering device is in operable communication with the forward turbine rotor wheel space and the HPPS bypass cavity to modulate the cooling air supplied to the forward turbine rotor wheel space from the HPPS bypass cavity. The metering device modulates the cooling air based on at least one operating condition of the turbine.

The heat exchanger for photovoltaic (PV) panels is a heat exchanger that maintains a uniform temperature for cooling PV modules. The heat exchanger is a box-shaped enclosure attached to the rear face of the PV panel. The enclosure has an inlet end, an outlet end, and a plurality of parallel baffles disposed between the ends defining a plurality of channels dividing fluid flow through the enclosure into parallel paths. The spaces between the ends of the baffles and the inlet and outlet ends define an inlet header and an outlet header. In one embodiment, the fluid inlet and outlet are disposed in diagonally opposite corners of the disclosure, opening into triangular input and output headers. In another embodiment, the fluid inlet and outlet are centered at the ends of the enclosure, and the outlet header is V-shaped with the vertex extending into the enclosure along its centerline.

An adapter (2) configured to be connected to a probe tube (12) for calibrating a hearing aid device (54) is disclosed. The adapter (2) comprises a tubular pipe member (4) and an opening (8) through which the adapter (2) is adapted to receive the probe tube (12), where the adapter (2) further comprises an input member (40) configured to be connected to an connection member (60) in order to provide fluid communication between the probe tube (12) and the connection member (60) through the adapter (2), where the probe tube (12) has an outer diameter (D 1 ) and where the tubular pipe member (4) comprises a cylindrical space (20) having an inner diameter (D 2 ) and a length (L 2 ). The outer diameter (D 1 ) of the probe tube (12) is 5-20%, preferably 8-15% smaller than the inner diameter (D 2 ) of the cylindrical space (20) of the pipe member (4) and that the length (L 2 ) of the cylindrical space (20) of the pipe member (4) is at least five times, preferably at least ten times larger than the outer diameter (D 1 ) of the probe tube (12). Hereby it is achieved that a long narrow gab (52, 52') can be provided between probe tube (12) and the pipe member (4) of the adapter (2) so that a sufficient acoustic seal can be accomplished.

A water pump that minimizes defects in which cooling water flows externally is provided. The water pump is provided with a rotating shaft supported by a body via a bearing, an impeller that is disposed at one end of the rotating shaft, and a seal member that is disposed between the impeller and the bearing. A drain passage that sandwiches the seal member and communicates with a space formed on the opposite side of the impeller is formed in the body, and a reservoir is formed downstream from the drain passage. At an upper position of a wall portion that forms the reservoir, a drain hole is formed, and a water-absorbing planar member is positioned in the reservoir.
