Abstract: The present invention relates to a method of retreading a tire and a retread tire (10) made by this method. The method comprises the steps of providing a tread layer (40) having a tread side (44) and a sole side (46) wherein the surface of the sole side (46) includes a plurality of tread elements (48) such as sipes and/or grooves or other void. Each tread element (48) has a first edge (64) and a second edge (66) at the surface of the sole side (46) of the tread layer (40). At least one of the first edge (64) and second edge (66) is formed to have a break edge (84) such as a rounded edge or a chamfered edge of 0.4 mm or more.

Title: Acknowledgement channel for wireless communications
Inventor: PALANKI RAVI
IPC: H04L1/16
Filed: 2007-10-24
Abstract: Systems and methodologies are described that facilitate establishing a forward link acknowledgement channel and transmitting acknowledgment signals thereupon. In particular, the signals can be spread within contiguous channel clusters in a tile where the signals in the cluster are mutually orthogonal to one another. Additionally, the signals can be multiplexed over a plurality of frequency regions. In this regard, the acknowledgment signals are diverse with respect to frequency and interference; moreover, the signals can be received and decoded even where one of the channels experiences high interference. Furthermore, the acknowledgement signals can also communicate a channel deassignment value, which allows devices to utilize persistent channels in communicating data to one another

Abstract: A treatment for bioprosthetic tissue used in implants or for assembled bioprosthetic heart valves to reduce in vivo calcification is disclosed. The method includes preconditioning, pre-stressing, or pre-damaging fixed bioprosthetic tissue in a manner that mimics the damage associated with post- implant use, while, and/or subsequently applying a calcification mitigant such as a capping agent or a linking agent to the damaged tissue. The capping agent suppresses the formation of binding sites in the tissue that are exposed or generated by the damage process (service stress) and otherwise would, upon implant, attract calcium, phosphate, immunogenic factors, or other precursors to calcification. The linking agent will act as an elastic reinforcement or shock- absorbing spring element in the tissue structure at the site of damage from the pre-stressing. In one method, tissue leaflets in assembled bioprosthetic heart valves are preconditioned by simulating actual flow conditions for a predetermined number of cycles, during or after which the valve is exposed to the capping agent.

Title: Self-expansible stent with radiopaque markers and method of making such a stent
Inventor: SCHLUN MARTIN
IPC: A61F2/915
Filed: 2008-09-05
Abstract: Pushing a self-expanding stent from one of its ends, during release of the stent at a stenting site in a bodily lumen, by proximal withdrawal of a surrounding sheath, can impose unacceptably high stresses on parts of the strut network of the stent.  For location of stents in a bodily lumen, it is customary to equip the end annulus of a stent with radiopaque markers. The present invention involves arranging the markers so that they share with non-marker portions of the end annulus the stresses imposed in the stent by the end pushing, whereby the high stresses are shared more equally by all the struts of the stent in the end annulus.

Abstract: The Telephone Gateway's unique design allows a tenant the ability to choose whom their home phone service provider will be, whether it be a land line based provider, or an IP  based provider. The Gateway allows the home phone line to work, without sacrificing the intercom system. Most intercom systems are based on a Non-Subscriber Line (NSL), which allows communication with the lobby through the telephone line. When an IP  based home phone system is installed, the installer had no choice but to cut the telephone line, in order for their equipment to work. The Telephone Gateway allows the installer to wire the land line directly into the unit, while at the same plugging their equipment into the corresponding phone jack. This saves time and money for the installer, the tenant, and the building owner, in the event that the customer moves, or chooses to switch back to a different company.

Abstract: A carrier for a femtocell is selected from a set of carriers available to femtocells. The femto node determines a preference order for the set and measures received signal strength (RSS) for each carrier. The femto node determines a least interference carrier from the set based on the RSS for each carrier, then defines a selected carrier for the femtocell by comparing the RSS of the least interference carrier to the RSS of other carriers in the set. The selected carrier may have a RSS larger than or equal to the RSS of the least interference carrier offset by a predefined margin. The comparisons may be performed in the preference order. The set available to femto nodes may be a subset of all carriers available to a combination of femtocells and macrocells and one or more of the carriers available to femtocells also may be a carrier available to macrocells.
