  • Patent number: 10353144
    Abstract: Embodiments of optical fiber may include cladding features that include a material (e.g., fluorine-doped silica glass) that may produce a very low relative refractive index difference with respect to cladding material in which the cladding features are disposed. This relative refractive index difference may be characterized by (n1?n2)/n1, where n1 is the index of refraction of the cladding material in which the cladding features are included, and n2 is the index of refraction of the cladding features. In certain embodiments, the relative refractive index difference may be less than about 4.5×10?3. In various embodiments, the configuration of the cladding features including, for example, the size and spacing of the cladding features, can be selected to provide for confinement of the fundamental mode yet leakage for the second mode and higher modes, which may provide mode filtering, single mode propagation, and/or low bend loss.

  • Publication number: 20190212001
    Abstract: A lighting module has a conducting track which is used to provide a current to lighting elements. The conducting track is also used as a source of a varying electromagnetic field for inductive power transfer, so that an external device may harvest energy from that field. A driver is used for providing a time—varying current which is adapted to illuminate the lighting elements and, in combination with the track configuration, is adapted to generate a varying electromagnetic field for inductive power transfer for energy harvesting by an external device.

  • Publication number: 20190205393
    Abstract: A cross-media search method using a VGG convolutional neural network (VGG net) to extract image features. The 4096-dimensional feature of a seventh fully-connected layer (fc7) in the VGG net, after processing by a ReLU activation function, serves as image features. A Fisher Vector based on Word2vec is utilized to extract text features. Semantic matching is performed on heterogeneous images and the text features by means of logistic regression. A correlation between the two heterogeneous features, which are images and text, is found by means of semantic matching based on logistic regression, and thus cross-media search is achieved. The feature extraction method can effectively indicate deep semantics of image and text, improve cross-media search accuracy, and thus greatly improve the cross-media search effect.

  • Publication number: 20190153418
    Abstract: Disclosed herein are methods for the isolation and purification of a botulinum neurotoxin (BoNT) protein, or a polypeptide comprising a receptor binding domain of BoNT, from a solution. The method comprises contacting the solution containing the protein or polypeptide to a matrix which has attached thereto a non-toxic non-hemagglutinin (NTNHA) under conditions appropriate for binding, washing the matrix to thereby remove unbound materials, and eluting the protein or polypeptide with a solution that dissociates the bound protein from the NTNHA. Conditions appropriate for binding are a pH of less than 7.5 (e.g, 6). Conditions appropriate for dissociation are a pH greater than or equal to 7.5 (e.g., 8). Compositions specific to the methods are also disclosed.

  • Patent number: 10197727
    Abstract: Holey fibers provide optical propagation. In various embodiments, a large core holey fiber comprises a cladding region formed by large holes arranged in few layers. The number of layers or rows of holes about the large core can be used to coarse tune the leakage losses of the fundamental and higher modes of a signal, thereby allowing the non-fundamental modes to be substantially eliminated by leakage over a given length of fiber. Fine tuning of leakage losses can be performed by adjusting the hole dimension and/or spacing to yield a desired operation with a desired leakage loss of the fundamental mode. Resulting holey fibers have a large hole dimension and spacing, and thus a large core, when compared to traditional fibers and conventional fibers that propagate a single mode. Other loss mechanisms, such as bend loss and modal spacing can be utilized for selected modes of operation of holey fibers.
