Abstract: Techniques and architecture are disclosed for a wireless fuze setter interface, comprising an electronics subsystem comprising a plurality of ports and a plurality of output interfaces having a common interface with the plurality of ports on the electronics subsystem. The plurality of output interfaces comprises an electrical energy transfer zone configured to provide electrical energy to the fuze, and a high speed data communications zone configured to transfer fuze setting data to the fuze. The wireless fuze setter interface provides fuze setting capability without the need for rotational or other physical alignment between the fuze and the fuze setter.

Abstract: Techniques and architecture are disclosed for a system that includes a fuze at a leading end of a projectile body and a fuze setter configured to engage the fuze and to program the same prior to launch. The system, in one example, includes a plurality of electrical contact pads on an exterior surface of a fuze radome housing and a plurality of electrical contact pins on the fuze setter. The electrical contact pads are arranged in a rotationally symmetric pattern that enables an electrical interface to be formed with the electrical contact pins, regardless of the rotational orientation of the fuze. Commutation is performed to rotate signals to the electrical contact pins instead of requiring that the fuze be physically rotated to bring the electrical contact pads into alignment with the electrical contact pins.

Abstract: A fuze setter interface for substantially simultaneously and wirelessly transferring power and data between a fuze setter and fuze. The fuze setter interface includes separate power and communications interfaces. In the power interface, an induction coil is provided in each of the fuze setter and fuze. Power is transferred by magnetic field coupling between the induction coils. In the communications interface, a communications member is provided in each of the fuze setter and fuze, along with appropriate functions to generate alternating-current (AC) waveforms, and condition, modulate or demodulate signals. In one example, both communications members are induction coils that transfer data by magnetic field coupling. In another example, both communications members are radio-frequency (RF) transceivers that transfer data by radio signal. The RF transceiver in the fuze may be a Height of Burst (HoB) sensor. In another example, both communications members are optical transceivers that transfer data by optical signal.

Abstract: Techniques and architecture are disclosed for a fuze setter adapter that operationally engages an incompatible fuze and fuze setter with each other so that fuze setting may be undertaken. The fuze and fuze setter each include at least one wireless or direct connect interface for electrical power transfer and/or data communications. The fuze setter adapter provides complementary interfaces configured to couple with the interfaces of the fuze and fuze setter. A processor control in the fuze setter adapter links the fuze setter adapter interfaces. The processor control is programmed to receive data communications from the fuze setter, convert those signals to fuze-compatible signals, and transfer the fuze-compatible signals to the fuze, and vice versa. The processor control is further programmed to receive electrical power from the fuze setter, convert that electrical power to fuze-compatible power, and transfer the fuze-compatible power to the fuze.

Abstract: A system for eliminating backlash associated with a precision guided projectile is provided. The system includes a canard assembly including at least one canard that is moveable, a rotation assembly operably engaged with the at least one canard, an input shaft of the rotation assembly, an output shaft of the rotation assembly operably engaged with the input shaft and operably engaged with the at least one canard of the canard assembly, a mechanical ground, an anti-backlash mechanism operably engaged with the output shaft and operably engaged with the mechanical ground, and a bias torque of the anti-backlash mechanism applied to the output shaft. The anti-backlash mechanism eliminates the backlash between the input shaft and the output shaft.
