Abstract: A system for controlling an aerospace vehicle by exploiting the dihedral effect to control bank angle of the vehicle by modulating sideslip. The control system includes a closed feedback loop comprising an outer loop for producing a sideslip angle command to induce a roll moment through the dihedral effect to satisfy a bank angle command, and an inner loop for taking the sideslip angle command, and possibly an angle of attack command to produce control input for flightpath hardware controls. Flightpath control hardware include pairs of flaps arranged longitudinally along the leading and trailing edges of an aeroshell of an aerospace entry vehicle to control pitch for changing the angle of attack, and another pair of flaps arranged laterally to control yaw for changing the bank angle via the sideslip angle, and also moving mass along ribs to control pitch and yaw. Thrusters can be fired to induce roll.

Abstract: The present invention is a wireless communication system and method. In an exemplary embodiment, the system includes a plurality of transceiver nodes arranged in a network and configured to communicate between transceiver nodes using an Orthogonal Domain Multiple Access (ODMA) frame structure, each of the plurality of transceiver nodes having neighboring nodes. Each ODMA structure may include a plurality of bootstrap slots for each of the plurality of transceiver nodes. Further, a plurality of correlation sequences may be defined within each of the plurality of bootstrap slots in which each correlation sequence included within the plurality of correlation sequences is located in a separate antenna sector and sub-sector. Addition of the plurality of correlation sequences to each of the plurality of bootstrap slots allows for recursive directional determination of which antenna sector and sub-sector is to be used to communicate with one of the plurality of transceiver nodes.

Abstract: A method of selecting linked metric measurements from at least one of open loop and closed loop measurements is disclosed. The method includes sending by a first node a first radio communication and receiving by a second node the first radio communication over a communication link. The method also includes estimating by a second node dynamics of the communication channel using at least one of the variance and mean deviation of linked metric measurements. The link metric measurements are at least one of symbol error rate (SER), packet error rate (PER), frame error rate (FER), bit error rate (BER), signal to noise ration (SNR), and received signal strength (RSS). The method also includes the use of the above link metric measurements by the second node as Open Loop metrics and the sending back of these metrics to the first node for use a Closed Loop metrics by the first node. The method also includes categorizing the dynamics of the communications channel into one of at least two groups based on the estimate.

Abstract: A method of coding a view in a CAD drawing comprises: identifying a feature of the view; extracting properties of the feature from the CAD drawing, the properties including vector properties associated with a graphic entity or group of entities which make up the feature; generating code bits representative of the extracted properties; adding the code bits to a view code for the view; and storing the view code. A CAD drawing is selected for retrieval from a database of drawings by producing a CAD source drawing having a source view, coding the source view to produce a source code as described above, comparing the source code with stored view codes, calculating a similarity index for each stored view code and selecting the drawing for retrieval from the database on the basis of the similarity index.

Abstract: A method of determining transmission parameters for a wireless transceiver is disclosed. According to the method, a state table is loaded into a transceiver. The state table includes a plurality of states, each of which has a set of transmission parameters associated therewith. Based upon characteristics of the signals received from a signal source, the transceiver is assigned a first state. The received signals are received and processed using the set of transmission parameters associated with the first state. It is determined whether an observed behavior of the received signals exceeds a threshold associated with the first one of the plurality of states. The transceiver is assigned a second state when the behavior exceeds the threshold. The received signals are received and processed using the set of transmission parameters associated with the second state.
