Topological spin textures in 3-dimensional magnetic structures
Utilizing the topological character of patterns in 3D structures is beneficial for information storage, magnetic memory and logic systems. One embodiment describes the use of topological knots, exemplified by a Möbius strip, in which a spin traversing along the band for a complete cycle will recover its original position, while having rotated away from its original orientation. The spins can respond to an external magnetic field, but cannot achieve a ferromagnetic state, in which all magnetic moments are pointing in the same direction, due to the topological knot. 3D assemblies of such nano-Möbius strips may form prototype secure magnetic information storage devices that are secure and with extremely low levels of energy dissipation. |

Optical subcarriers may be employed to transmit data in a point-to-multi-point network whereby a hub node including a network switch receives such data from a client and transmits information indicative of such data to multiple leaf or network nodes, where data intended for such leaf node is output.

Moreover, the client data may have a format that is different than that associated with the transmitted information indicative of the client data. Consistent with the present disclosure, client data is inverse multiplexed to lower data rate streams and then multiplexed to a plurality of inputs, each of which corresponding to a respective optical subcarrier. Information indicative of the data may be allocated to multiple subcarriers, if the a single carrier lacks sufficient capacity or bandwidth to meet the bandwidth requirements of the leaf node. Buffer circuits may also be employed to “shape” or delay the outputs or flows of the multiplexer so that data is fed, for example, to a transmit portion of chip 200b of the network switch at a uniform rate rather than in non-uniform data bursts, which, under certain circumstances, could exceed the capacity of such transmit portion. In a further example, leaf nodes include circuitry for monitoring the amount of received data, and, if such received exceeds a certain threshold, a request is sent from the leaf node to the hub to transmit data at a rate equal to or substantially equal to the received data rate. As a result, symmetric data flows may be achieved whereby the leaf nodes transmit and receive data at the same or substantially the same rate. |

Reducing harmonic distortion by dithering
A digital signal generation assumes that a base frequency (the frequency with which the primitive phase angles are specified relative to) is equal to the carrier frequency for all relevant times. But this causes errors in the digital signals output to each array element transducer. Thus, it is necessary for the development of a signal generation system that is capable of producing a digital signal using the free selection of amplitude and phase. This is used to produce a substantially error-free signal that preserves the amplitude and phase relative to a constant base frequency while allowing the carrier frequency to vary. |
