Title: Methods and systems for enhancing fluid flow through an obstructed vascular site
Inventor: JOHANSSON PETER K
IPC: A61K45/06
Filed: 2001-03-06
Granted: 2014-12-30
Abstract: Methods of enhancing fluid flow through a vascular site occupied by a vascular occlusion, as well as systems and kits for use in practicing the same, are provided. In practicing the subject methods, the vascular site is flushed simultaneously with a first dissolution fluid (e.g., an organic matter dissolution fluid and/or an inorganic matter dissolution fluid), and a second dissolution fluid attenuating fluid, where flushing is carried out in a manner such that only a surface of the vascular occlusion is contacted with the non-attenuated dissolution fluid. Examples of dissolution fluid/dissolution fluid attenuating fluid pairs include: (1) oxidizing agent fluid and fluid comprising oxidizable neutralizing agent; (2) surfactant fluid and phosphate buffered saline; (3) acidic solution and phosphate buffered saline; etc.  Flushing is carried out in this manner for a period of time sufficient for fluid flow through the vascular site to be enhanced, e.g. increased or established. The subject methods, systems and kits for practicing the same find use in the treatment of a variety of different vascular diseases characterized by the presence of vascular occlusions, including both partial and total occlusions.

Patent CA-2430980-C (CA)
Inventor: RITTER DAVID C
IPC: B32B21/00

Granted: 2008-02-12
Abstract: The method of this invention adheres a low emissivity radiant barrier material to an underlying lignocellulosic substrate within the primary manufacturing operation of the underlying lignocellulosic substrate. Thus, a - radiant barrier covered substrate is formed by integrally joining the radiant barrier covering to a mat of lignocellulosic material during consolidation thereof with a first adhesive bonding material to form an underlying substrate. The integral joining operation can, for example, be accomplished by bonding the radiant barrier covering to a lignocellulosic mat in a product formation press. This is typically accomplished using a second adhesive bonding material for adhesion of the radiant barrier material to the lignocellulosic mat, and a first adhesive bonding material for consolidating the lignocellulosic mat to form a lignocellulosic substrate. More specifically, this invention is directed to a method whereby a low emissivity radiant barrier material is joined in situ to a mat of lignocellulosic particles using a second adhesive material, during the consolidation of the lignocellulosic particles and a first adhesive bonding material to form an underlying substrate, an integral laminated radiant barrier covered lignocellulosic product being produced.

Title: Device for modem relay channel termination
Inventor: GROVE VINCENT T
IPC: H04L12/64
Filed: 2003-05-09
Granted: 2011-09-20
Abstract: A modem data aggregating gateway that supports modem relay functionality for permitting reliable switching of modem traffic between a VoIP network and a data packet switch Internet Protocol (IP) network, s.a. the Internet. The modem relay aggregator may receive modem data encapsulated as Voice over IP  (VoIP) data packets in accordance with a Simple Reliable Protocol Transport ((SRPT) mechanism. The packet data may be error corrected and/or decompressed before being repackaged for forwarding to the ultimate destination. In the event that the destination is itself an IP device, the modem relay aggregator may forward the packets directly over the IP network. As result, if the destination of a modem call is an IP device (such as a Web site or other Internet-enabled device) the technique eliminates two points from a processing path in which digital signal processing (DSPs) would otherwise have to perform modem protocol processing. Otherwise, minimal modem reformatting can be performed at the aggregation point.
