Abstract: A flasher module, installable on a ladder, incorporates multiple high-intensity light-emitting diodes (LEDs), which are coupled to an electro-chemical power source (battery or single cell). The LEDs may be wired for a continuous “ON” condition, but are preferably connected to flasher circuitry. For maximum visible intensity, the flasher circuitry is designed so that all LEDs flash simultaneously about one to two times per second. A first embodiment flasher module is sized to install within the uppermost portion of a ladder rail of C-shaped cross section. A second embodiment module, which provides a larger viewing angle, incorporates the LEDs within a bar that is mountable beneath the uppermost rung of the ladder. Either embodiment of the invention may be equipped with a gravity-actuated switch, which will turn on the flasher circuitry whenever the ladder is deployed at an angle greater than 45 degrees from horizontal.

Abstract: Copolymers having repeating units derived from monocyclic esters or carbonates and certain bicyclic diesters and/or carbonates have controllable rheological properties. The bicyclic diester and/or carbonate copolymerizes easily with the monocyclic monomers, especially with lactide, to form copolymer that can have tailored levels of branching. The copolymers have excellent rheological properties, including increased melt tensions and improved shear thinning, compared to the analogous linear polymers.

Abstract: The present invention relates to a method for preparing polymeric films, preferably electroactive films, with enhanced physical properties by the steps of applying to a substrate a solution of a polymer containing pendant labile solubilizing groups, then removing the solvent and a sufficient concentration of the labile solubilizing groups render the polymer less soluble in the solvent than before the labile groups were removed. It is believed that the removal of pendant soluble groups a) permits optimization of the semiconducting backbone for charge transport performance, b) allows direct control of microstructure in the final film, and c) renders the final film more robust during subsequent process steps needed to construct multilayer devices.
