The invention relates to a web or filter structure such as the filtration media comprising a collection of fiber comprising a first polymer and a second polymer in a fine fiber or fine fiber web structure. The combination of two polymers provides improved fiber rheology in that the fiber has excellent temperature and mechanical stability. The combination of polymers imparts the properties of elasticity or tackiness, which is desirable for adhering particles to the fiber web, with high temperature resistance.

A method and system for maintaining uniformity in a FLIR display. During a one-time initialization procedure, a plurality of dynamic ranges are defined by covering a specific range of bucket fill levels when in a certain gain. To cover all dynamic ranges possible, a plurality of pairs of responsivity equalization (RE) calibrations (each pair producing a RE set of pixel gain corrections) are also accomplished in the same one time initialization period. A plurality of corresponding level equalization (LE) calibrations (each using the appropriate calibrated RE set and producing a LE set of pixel level corrections) for each anticipated dynamic range are made at every power-up initialization. Each of the calibrations is done with respect to a thermal reference source to produce a uniform scene at the desired bucket fill level. An algorithm is employed which forces the two bucket fill points defined during the responsivity calibration to span as far as possible the dynamic range and forces the level equalization bucket fill point to fall within the two bucket fill points of the responsivity calibration. Then, during an operational time period, the scene and optics temperatures are monitored, and if the average bucket fill value exceeds the bucket fill range of the present dynamic range, the presently selected dynamic range is changed to a second dynamic range (gain is changed along with the RE set and LE set). The dynamic ranges are designed to overlap so that a hysteresis effect is achieved. The pre-calibrations and automatic dynamic range switching prevent saturation and create the best uniformity (lowest fix pattern noise) possible while allowing for continuous operation of the FLIR system, thus eliminating the interruption caused by the prior art touch-up calibration procedure.

Living cells are modified at their surface with specially selected polymers. Covalently attaching specially selected polyethylene glycol (PEG) derivatives to the surface of red blood cells (RBC) in aqueous media under mild conditions is a preferred example. The selected PEG derivatives dramatically reduced aggregation and low shear viscosity of RBC resuspended in autologous plasma, and inhibited RBC agglutination by blood group-specific antibodies. The morphology and deformability of the PEG-treated cells were unaltered. PEG coating of the RBC surface is applicable to the treatment of a variety of diseases characterized by vaso-occlusion or impaired blood flow, e.g., myocardial infarction, shock, and sickle cell disease. An infusion solution is prepared containing red blood cells covalently bound to a PEG derivative having a molecular weight of between 2,000 and 5,000 Daltons and a PEG derivative having a molecular weight between 10,000 and 35,000 Daltons.

The present disclosure relates to a particularly effective well configuration that can be used for SAGD and other steam based oil recovery methods. Fishbone multilateral wells are combined with SAGD, effectively expanding steam coverage. Preferably, an array of overlapping fishbone wells cover the pay, reducing water use and allowing more complete production of the pay.

A computer-implemented method is disclosed for creating a distributed antenna network for use in designing a generally wireless communications network. The method includes the placing and interconnecting, on a design screen canvas, of network components, selected from a components database stored in a computer system, with several signal source systems having different parameters. The method also generally includes the verification of the compatibility of the different interconnected components and signal sources and the notification of incompatibility if any. The method further generally includes the calculation, at each interconnection, of the uplink and the downlink link budgets for each signal source. The method also includes the displaying of graphical representations of the estimated propagation of the signals according to the parameters of each signal source. A computer system for supporting the method is also disclosed.

An inlet valve is partially coated with a protective coating to resist corrosion and gas impingement when used in an internal combustion engine. The inlet valve has a hard cladding that is shaped to function as a valve seat. The hard cladding forms an interface with the valve head body, which is typically made of a softer metallic material than the hard cladding. The protective coating is bonded to the inlet valve and covers the cladding-body interface. The protective coating is resistant to corrosion, wear from gas impingement, and can withstand the high temperatures reached in internal combustion engines. Internal engines incorporating the valves are more durable and less susceptible to catastrophic valve failure. A method for making the inlet valves generally includes masking a portion of the valve stem and the valve seat, applying a protective coating to cladding-body interface, and curing the protective coating or otherwise bonding the protective coating to the inlet valve.

A walking cane clamp is provided which includes a clip dimensioned and configured to releasably secure the walking cane clamp to a support member, the clip being attached to a cane fastener, the cane fastener including a body portion and a biasing member pivotally attached to the body portion, the body portion defining an opening and a receptacle dimensioned and configured to receive a portion of a cane shaft, the biasing member defining an open position and a closed position of the receptacle, the biasing member being pivotally biased toward the closed position in which a portion of the biasing member covers a portion of the opening sufficient to secure the cane shaft within the receptacle. Also provided is a system for securing a walking cane to a walker or a rollator which includes a walking cane clamp as described herein and a base for receiving the walking cane. Also provided is a walker or rollator which includes a walking cane clamp as described herein and an optional base for receiving a walking cane.
