Latest Patents
One of his latest inventions is the Portable Convertible Blast Effects Shield. This rapidly deployable shield features a set of two or more frusto-conically-tapered telescoping rings that can be converted between a telescopically-collapsed configuration for storage and transport, and a telescopically-extended upright configuration that forms an expanded inner volume. In its first embodiment, the upright configuration provides shielding against blast pressures, shrapnel, and fireballs. In the second embodiment, it offers ballistic shielding against incoming weapons fire and shrapnel. Each ring is constructed from high-strength materials, such as composite fiber and matrix materials, which effectively inhibit blast effects and prevent projectiles from penetrating the shield. The rings are designed to be releasably securable to each other in the upright configuration, utilizing friction fits or click locks.
