Lung volume reduction is performed in a minimally invasive manner by isolating a lung tissue segment, optionally reducing gas flow obstructions within the segment, and aspirating the segment to cause the segment to at least partially collapse. Further optionally, external pressure may be applied on the segment to assist in complete collapse. Reduction of gas flow obstructions may be achieved in a variety of ways, including over inflation of the lung, introduction of mucolytic or dilation agents, application of vibrational energy, induction of absorption atelectasis, or the like. Optionally, diagnostic procedures on the isolated lung segment may be performed, typically using the same isolation / access catheter.

A minimal incision maximal access system allows for maximum desirable exposure along with maximum access to the operative field utilizing a minimum incision as small as the METRx and Endius systems. Instead of multiple insertions of dilating tubes the design is is a streamlined single entry device to avoid repetitive skin surface entry. The system offers the capability to expand to optimum exposure size for the surgery utilizing hinged bi-hemispherical or oval working tubes applied over an introducer obturator which is controllably dilated to slowly separate muscle tissue. Deeper end working and visualization areas with maximum proximal access and work dimensions are provided to makes the operative procedure safer in application and shorten the surgeons's learning curve because it most closely approximates the ability to use open microdiskectomy techniques.

A layer two forwarding protocol (L2F) provides virtual direct dial-up service into private networks through public internet service providers. An authorized remote client appears as a direct dial-up client to the home gateway, even through the client is accessing the home gateway remotely through the ISP. The new forwarding protocol allows the remote client to conduct point-to-point link protocols, such as point-to-point protocol (PPP) and serial line interface protocol (SLIP) directly with the local network home gateway. The network access server changes from a routing mode where a communication protocol is conducted with the client to a switching mode where the POP simply sends data from one port to a tunnel. The tunnel then transmits the data to another port, regardless of the header information on transmitted data packets. The remote client can then be managed through databases controlled by the local network and gain access to resources not typically accessible through the internet. The layer two forwarding protocol conducts an independent authorization session to prevent unauthorized access to the private network and provides point-to-point protocol transport over the internet independently of internet transport protocols.

This invention discloses a hollow-body guitar with a large rectangular sound hole between the neck and bridge, with two pickup mounting slots on each side of the sound hole in removable top plates, including a system of top plates and mounting adapters for 7 different single-coil and dual-coil pickup types. The invention has a system humbucking pickup circuit mixing modules that can be cascaded in linear or tree form to mix all the types of pickups in the output, providing a much wider range of tones than current 3-way and 5-way switching systems. For example, three matched single-coil pickups and one humbucker can be mixed to provide 19 humbucking circuits and 18 circuits with hum. Mixed a different way, using switchless analog circuits, they can produce the tones of all 19 switched humbucking circuits, plus all the continuous variations in between.

A device for adjusting the length of a cord for carrying a wind instrument comprises two parts which can be pushed into one another, of which the first cup-shaped part has a recess and four openings and the second part has, as insert, a groove with a U-turn as well as a recess and two guide grooves. A cord piece is guided around the groove, out of the device and through an eyelet of a hook. A further cord piece is guided through the guide grooves and the four openings. The device allows the cord piece to be guided through the groove, which is completely separated from the guidance of cord pieces through the guide grooves. The guide grooves contain elements for deflecting and inhibiting the movement of the cord pieces. The device enables a stable and torsion-proof handling of the length adjustment of the cord. The device makes it possible that the cord length cannot adjust automatically, not even if the cord is not tensioned.
