Abstract: The present invention is directed to an apparatus and method of solder-sealing an active matrix OLED display using a monochromatic solid-state laser beam (1). The solder-sealing apparatus comprises a cover assembly (13) adapted to be positioned over at least one OLED (11) on a substrate (10), a sealing band (12) surrounding each OLED, a chuck assembly (20) with an array of heat sinks (21) that align with the OLEDs, a pick-up assembly (30) with at least one aperture (33), and a flange assembly (132) to which a solder pre-form (133) is secured.

The sealing band (12) and solder pre-form (133) are aligned and pressed together by the pick-up assembly (30), and the focused laser beam (1) is projected through the chuck assembly to seal the OLEDs (11) within the cover assembly (13).

Abstract: My business method for concrete coverage insurance or service contracts for home or business owners is calculated by figuring the square footage of an area and linear footage for foundations. The premium is figured by demographics with deductibles in place for high or low loss, which sets the premium. Policy duration will be determined by experience of loss, but for the time being, will last between 1 and 5 years, and will be transferable. This is possible using all the technology an insurance company has to offer in the industry today with inspections on a property depending on demographics. This will be coverage that is not now written by any company. This will be a valuable business to most concrete companies in repair, both new and replacement. The trained inspector will catch problems before they become major structural problems. At the same time, the company will be training property owners on loss prevention and maintaining their concrete.

The high performance electron emitter material of the invention may comprise a high Cr and SiO mixture.
