| 8089108 | Double-gated transistor memory Memory cells are constructed from double-gated four terminal transistors having independent gate control. DRAM cells may use one, two or three transistors. Single transistor cells are constructed either with or without a bit storage capacitor, and both NAND- and NOR... | 01/03/2012 |
| 8072006 | Double-gated sensor cell A high quality imager is constructed using a silicon-on-insulator (SOI) process with sensors fabricated in the SOI substrate and isolated by the buried oxide (BOX) from associated readout circuitry in the SOI layer. Handle windows are opened in the SOI device layer ... | 12/06/2011 |
| 8056677 | Lift system with articulably joined subchassis This lift system serves as a powered ladder having a small footprint. The system is divided into two subchasses with a mast fixedly attached to a first subchassis for support of a liftable platform which may carry a human operator. Maneuverability is accomplished by... | 11/15/2011 |
| 7982662 | Scanning array for obstacle detection and collision avoidance This scanning array scans an area around the array for nearby objects, collision obstructions, and terrain topography. The scanning array can scan for sounds emitted by objects in the vicinity of the scanning array, passive energy receipt sources, or it can also sen... | 07/19/2011 |
