| 20120127833 | ACOUSTIC POWER AND DATA TRANSMISSION THROUGH A SOLID MEDIUM - A system for transmitting power and data through a solid medium includes a power signal transmitter configured to acoustically transmit power through the solid medium to a power signal receiver using a first frequency and a data signal transmitter configured to acoustically transmit data through the solid medium to a data signal receiver using a second frequency. The second frequency may be offset from the first frequency and from at least a first overtone of the first frequency. Furthermore, the data signal transmitter and data signal receiver may be positioned at a null of a pattern of acoustic waves produced by operation of the power signal transmitter. The system may further include a notch filter coupled to receive an electrical output of the data signal receiver, the notch filter being tuned to attenuate the first frequency. | 05-24-2012 |
| 20120026041 | SYSTEMS AND METHODS FOR LOCATING A TARGET IN A GPS-DENIED ENVIRONMENT - A system for locating an object in a GPS-denied environment includes first and second stationary nodes of a network and an object out of synchronization with a common time base of the network. The system includes one or more processors that are configured to estimate distances between the first stationary node and the object and a distance between the second stationary node and the object by comparing time-stamps of messages relayed between the object and the nodes. A position of the object can then be trilaterated using a location of each of the first and second stationary nodes and the measured distances between the object and each of the first and second stationary nodes. | 02-02-2012 |
