Abstract: Implementations disclosed herein may include receiving from a user a selection of at least one die, a package type, and at least one test condition; generating, using a processor, a product die configuration and a product package configuration using a predictive modeling module and the at least one die and the package type; generating a graphic design system file; generating a package bonding diagram; generating a product spice model of the discrete device product using a technology computer aided design module; generating, using a processor, one or more datasheet characteristics of the discrete device product with the product SPICE model; generating a product datasheet for the discrete device product using the graphic design system file; and using a second interface generated by a computing device to provide access to the graphic design system file, the package bonding diagram, the product datasheet, and the product SPICE model.

Abstract: A hand-held flashlight has a housing for two independent electrical systems: a primary system and a backup system. Each of the systems includes a light source, a power source and a switching device for selectively connecting a power source to a corresponding light source. The backup system uses high performance components to insure that the flashlight is operational for long time periods. The backup system is actuated only after the the primary system has failed. An indicator announces when the backup system is in operation.
