| 12553987 | 2/17/2026 | Georgia Tech Research | Atlanta-Sandy Springs-Marietta, GA | Ultrawideband localization systems and methods for computing user interface | An exemplary system and method are disclosed for a handheld or hand-enclosed instrument configured with ultra-wideband localization using unidirectional messaging protocol based on time difference of arrival (TDoA) measurements that can be used as inputs, in a realtime control loop, to a software application that uses the handheld or hand-enclosed instrument as an input user interface. The handheld or hand-enclosed instrument can be readily employed for UI in large work areas (e.g., 2D), such as a whiteboard or wallboard, with sub-millimeter resolution and sub-millisecond latency. The handheld... |
| 12555902 | 2/17/2026 | VIASAT | San Diego-Carlsbad-San Marcos, CA | Antenna apparatus employing radiation shield for integrated circuits | An antenna apparatus includes a radiation shield between an antenna element and at least one radio frequency integrated circuit (RFIC) coupled to the antenna element. An antenna substrate includes a first dielectric layer having opposite first and second surfaces, and a first metallization layer attached to the second surface to form a ground plane. A base substrate includes at least one second dielectric layer having opposite third and fourth surfaces, and a second metallization layer having a first side attached to the third surface and a second side attached to the first metallization layer... |
