TS-062601 — Only a small fraction of the radio frequency (RF) energy transmitted by smartphones and other wireless devices is used to communicate with a wireless access point. It would be useful to collect or harvest the unused RF signals in order to convert them to direct current (DC) power and supplement th…

TS-062596 — Conventional rectifying circuit designs convert alternating-current (AC) signals into direct-current (DC) signals via the used of diodes. Low-barrier Schottky diodes are used in low AC power cases such as with ambient radio frequency (RF) signals. Ideally, each diode is only turned on during the p…

TS-061849 — The Rare Earth Element Trap-Extract-Precipitate (REE-TEP) process is a cost-effective and environmentally benign approach to recover rare earth elements (REEs) from acidic waste streams. It involves beneficial reuse of readily available industrial by-products and a naturally occurring organic ligand resulting in REE concentrate that can be commercially processed to produce rare earth oxides (REOs).
