Abstract: A course correction system for a projectile can include a pre-steering trajectory determination module. The pre-steering trajectory determination module can be configured to receive a series of possible trajectories from an estimation module including a physical model defining trajectory as a function of gravitational pull and one or more launch variables, and receive a sensor data from one or more on-board sensors of the projectile. The pre-steering trajectory determination module can also be configured to reduce the possible trajectories from the estimation module to one or more refined trajectories using the sensor data, and output the one or more refined trajectories.

Abstract: A plurality of users may interact with a content distribution system in order to share digital media content. The system may receive, store, and/or publish a delivery specification that includes requirements relating to digital content that a first user wishes to receive. The delivery specification for the digital content may include one or more requirements of the digital content to be received. A second user who wishes to provide the digital content may access the delivery specification. The system provides for flexible validation of the media content from the second user. For example, validation may occur at device of the first user, at a device of the second user, and/or at a device of the content distribution system. Upon validation of the media content from the second user, the system may facilitate transfer of the media content from the second user to the first user.

Abstract: A method of controlling a projectile includes initiating an execution mode if a roll control authority parameter is outside of a pre-determined operating range for a projectile. The execution mode includes bypassing a guidance command and sending a modified command to execute a coning maneuver to improve control response of the projectile. A projectile control system includes a processor operatively connected to a memory. The memory has instructions recorded thereon that, when read by the processor, cause the processor to execute the method operations described above.

Abstract: A programmable modulator (100) is programmable to operate in either of a GMSK or 8PSK mode. When operating in a GMSK mode, a signal modulating circuit 105 receives (210) a bit stream (110), maps the bit stream (110) to a phase value in complex I, Q form and applies a progressive rotation to the phase value according to GMSK specifications. The output (140) is filtered by a filter circuit (135), preferably using a complex Finite Impulse Response (FIR) filter using the standard coefficients for an 8PSK modulation to create (215) an approximate GMSK output (165). A GMSK correction circuit (150) determines a correction term that is added to the filter circuit output (165) so as to correct amplitude variations to allow the output to conform to GSM/EDGE standards. The same modulator (100) may be programmed to operate in an 8PSK mode with linear predistortion.

Abstract: Disclosed is an agitator assembly which comprises an agitator and means for mounting the agitator assembly on top of a tank. The agitator comprises a shaft, a propeller fixed to one end of the shaft, and means for rotating the shaft to provide an axial discharge from the propeller of at least 4.0 m/sec with a flow equivalent of at least 0.2 tank volumes/minute. The agitator is mounted on top of the tank so that the shaft enters the tank at an angle a to the longitudinal axis of the tank of between about 30 and about 60 degrees and at an angle &bgr; to the transverse vertical axis of the tank of less than about 50 degrees. Also disclosed is a method of shipping solids that are soluble in a solvent. The solids are placed in a tank on which the agitator assembly has been mounted. The quantity of solids placed in the tank exceeds the amount that will dissolve when the tank is filled with the solvent. The tank is transported to the location where the solids are to be removed from the tank.

Abstract: A buried channel to surface channel charge coupled device includes a blocking gate and a transfer gate situated between a buried channel gate and a surface gate for transferring electron charge from the buried channel to the surface channel. The blocking gate is located over the buried channel and the transfer gate straddles the buried and surface channels. The blocking gate serves to overcome the potential barrier associated with buried to surface channel transfers.
