Abstract: Digital cloaking is a method for practical cloaking, where space, angle, spectrum and phase are discretized. At the sacrifice of spatial resolution, a good approximation to an ideal cloak can be achieved—a cloak that is omnidirectional, broadband, and operational for the visible spectrum, three-dimensional (3D), and phase-matching for the light field, among other attributes. One example of a digital cloak is an active cloak that uses lenticular lenses, similar to integral imaging for 3D displays. With the continuing improvement in commercial digital technology, the resolution limitations of a digital cloak may be minimized, and a wearable cloak can be implemented.

Abstract: This invention concerns a device for the transmission of impulse and momentum, e.g. from a shock wave from an explosion or momentum from objects impacting the device, from one location to another, and is primarily used to protect vehicles, ships, aircrafts and buildings against impulse and/or momentum, for instance in regards to attacks on those with grenades, bombs, mines and the like. The governing physical principles are those of conservation of momentum and energy, and Newton's 3rd Law, claiming that for every action there is an equal but opposite reaction. When the receiver 1 is accelerated by the incoming shock wave 9 it collides with the transmitter 2, connected to an emitter 3, momentum is transferred to the emitter 3. If the transfer is in itself not sufficient to bring the receiver's 1 velocity to an acceptable level, additional energy and momentum is added through the transmitter 2.

Abstract: A system operating in a dead reckoning mode accumulates relative yaw measurements, i.e., measurements of rotation about a z-axis, made by one or more over mechanization update intervals and produces dead reckoning mechanization update values. The system accumulates the values over a turn rate accumulation period, calculates a yaw rate and determines if the yaw rate exceeds a turn rate threshold. If so, the system directs an INS filter to perform a zero yaw rate update at the start of a next mechanization update interval, to correct for the z-axis drift errors of the gyroscopes based on the sensed rotation in the relative yaw measurements over the previous mechanization update interval. The system then sets the z-axis drift errors to zero. If the system determines that the yaw rate exceeds the turn rate threshold, the zero yaw rate update is not performed at the start of the next mechanization update interval.
