International Classification:

H01L021/66

US Classification:

438 14, 438 15, 438 18, 257 48, 257777, 257778, 257782, 257784

Abstract:

A semiconductor die adapter assembly includes a semiconductor die cut from a wafer, the die having an active surface including bond pads. A die adapter, also having bond pads, is bonded to the semiconductor die. Die-to-adapter connectors electrically connect the die bond pads to the adapter bond pads. Finally, adapter-to-substrate connectors electrically connect the adapter bond pads to a device substrate. Having bond pads on the die adapter eliminates the need to break and remake the electrical connections to the original bond pads on the die during burn-in testing of the die.

US Classification:

556137

Abstract:

Bis-platinum complexes having the formula ##STR1## wherein A is a ligand having two pairs of platinum-coordinating acidic groups which are each independently a carboxylate, phenolate, sulfonate or phosphonate group, each said pair being capable of coordinating with a platinum ion to form a 5-10 membered chelate ring; Z is a water-solubilizing group; n is 0 or a positive integer, with the proviso that n is 0 only when at least one of said platinum-coordinating acidic groups is sulfonate or phosphonate or when at least one platinum ion is a Pt(IV) ion; and R. sub. 1, R. sub. 2, R. sub. 3, R. sub. 4, R. sub. 5 and R. sub. 6 are each independently H or a C. sub. 1-20 alkyl, aryl, aralkyl, or alkaryl group, or together form one or more C. sub. 1-30 alkylene, cycloalkylene, arylene, aralkylene or alkarylene groups; or a pharmaceutically acceptable salt thereof, are useful as readily water-soluble antitumor agents.

A43B 702

US Classification:

320107

Abstract:

The invention comprises a means for generating energy while walking or running for storage in a rechargeable battery. One embodiment uses lever arm movement in the heel of a shoe resulting from normal walking or running to generate energy from a built-in generator. The linear or rotational motion of the lever arm engages the circular gear assembly and turns the generator/motor/turbine, thus generating power. The second embodiment uses fluid reservoirs embedded in the shoes. Pressure changes resulting from normal walking or running moves the fluid through a narrow channel connecting two reservoirs, thus generating power by rotating a flywheel and an attached motor/generator/turbine in the middle of the channel. Secondary (rechargeable) batteries are incorporated into the invention either in an integrated form or as an add-on design. Additional features include a digital diagnostic data output, which would serves as a "fuel gauge" for the secondary batteries, and a smart charging circuit that efficiently controls battery charging from a generator output that varies with step rate and force.
