Patent NZ-745718-A (NZ)
Title: Negative ion-based neutral beam injector
Inventor: BELCHENKO YURI I
IPC: H01J27/02
Filed: 2013-09-04
Abstract: Until quite recently, the neutral beams used in magnetic fusion research, material processing, etching, sterilisation and other applications were all formed from positive ions. Neutral beams require energies well beyond that accessible with positive ions. Negative-ion-based neutral beams have been developed in recent years. However, beam currents achieved so far are significantly less than that produced quite routinely by positive ion sources. A negative ion-based beam injector comprises an ion source adapted to produce a negative ion beam, wherein the ion source includes a plasma box with internal walls maintainable at elevated temperatures of about 150-200° C, a pre-accelerator, a high energy accelerator interconnected to and spaced apart from the pre-accelerator and ion source by a transition zone interposing the pre-accelerator and the high energy accelerator, wherein the transition zone comprises a pair of deflecting magnets that enable a beam from the pre-accelerator to shift off axis from an axis of the pre-accelerator and onto a non-coaxial axis of the accelerator before entering the high energy accelerator, wherein the pre-accelerator include one or more positively biased electrodes to repel back streaming positive ions.

Patent NZ-759665-A (NZ)
Title: Deep learning-based techniques for pre-training deep convolutional neural networks
Inventor: FARH Kai-How
IPC: G16B20/00
Filed: 2019-05-09
Abstract: The technology disclosed includes systems and methods to reduce overfitting of neural network-implemented models that process sequences of amino acids and accompanying position frequency matrices. The system generates supplemental training example sequence pairs, labelled benign, that include a start location, through a target amino acid location, to an end location. A supplemental sequence pair supplements a pathogenic or benign missense training example sequence pair. It has identical amino acids in a reference and an alternate sequence of amino acids. The system includes logic to input with each supplemental sequence pair a supplemental training position frequency matrix (PFM) that is identical to the PFM of the benign or pathogenic missense at the matching start and end location. The system includes logic to attenuate the training influence of the training PFMs during training the neural network-implemented model by including supplemental training example PFMs in the training data.

Title: Systems and methods for mapping virtual radio instances into physical volumes of coherence in distributed antenna wireless systems
Inventor: FORENZA ANTONIO
IPC: H04L27/00
Filed: 2015-02-04
Abstract: Systems and methods are described for mapping Virtual Radio Instances (VRIs) into physical volumes of coherence in a Multiple Antenna System (MAS) with Multi-User (MU) transmissions (“MU-MAS”). These mapping methods enable communications through simultaneous non-interfering data streams in the same frequency band between the MU-MAS and multiple users, within their own volume of coherence. As the users move, their VRIs follow their respective volumes of coherence via teleportation to adjacent MU-MAS networks, thereby eliminating the need for handoffs as in conventional cellular systems and unnecessary control data overhead.

Patent PT-100180-A (PT)
Inventor: WEBER GERALD MARTIN
IPC: B32B37/00
Filed: 1992-02-28
Abstract: An improved method and apparatus for incrementally stretching "zero strain" stretch laminate webs to impart elasticity thereto in the direction of initial stretching, at least up to the point of initial stretching. The "zero strain" stretch laminate material is formed of at least two plies of material which are either intermittently or substantially continuously secured to one another along at least a portion of their coextensive surfaces while in a substantially untensioned ("zero strain") condition. One of the plies is stretchable and elastomeric, while the second ply is elongatable, but not necessarily elastomeric. The second ply will, upon stretching of the laminate, be at least to a degree permanently elongated so that, upon release of the applied tensile forces, it will not return to its original undistorted configuration. This results in z-direction bulking of the laminate web when the applied tension is released as well as subsequent elastic extensibility in the direction of initial stretching, at least up to the point of initial stretching. In a particularly preferred embodiment of the present invention the opposed peripheral edge portions of the laminate web to be incrementally stretched are subjected to restraint to substantially prevent inwardly directed slippage or contraction thereof in a direction parallel to the direction of stretching. This maximizes the effectiveness of the incremental web stretching operation by forcing the "zero strain" stretch laminate web to undergo the fullest possible degree of elongation during the incremental stretching operation.
