  • Patent number: 10306942
    Abstract: Safety head wear for use for example in high risk activities such as sports and industrial purposes where protection from head injuries is required. Components are provided inserted between the liner and outer shell and consists of two parts; a chamber or bladder and a fluid or gel like material. The fluid or gel material is contained in the chamber or bladder and is positioned in such a way to create low friction between the surface of the shell and liner or liner and head. It can also be used on the outer surface of the shell or placed within two layers of the liner. The device provides a method of independently managing both compression and shear force characteristics of the helmet around the head designed to decrease brain trauma resulting from high linear and angular acceleration during impacts to the helmet.

  • Publication number: 20190125827
    Abstract: Methods for modulating lysosome-mediated microautophagy of a lipid or protein substrate in a cell are provided herein. In certain embodiments, said methods may comprise increasing lysosome-mediated microautophagy by treating the cell with a microautophagy-enhancing agent which increases lysosomal association-dissociation events between lysosomes and the cellular lipid or protein substrate and/or increases lysosomal degradation capacity; or decreasing lysosome-mediated microautophagy by treating the cell with a microautophagy-reducing agent which reduces lysosomal association-dissociation events between lysosomes and the cellular lipid or protein substrate and/or decreases lysosomal degradation capacity; thereby modulating lysosome-mediated microautophagy of the lipid or protein substrate.

  • Patent number: 10233442
    Abstract: The disclosure relates to a switchable aptamer having a high affinity for a selected target such as a virus, cell or antibody when in the presence of a binding ion and a low affinity for said target in the absence of said binding ion. The switchable aptamer may be isolated or selected from a pool comprising a mixture of aptamers by incubating the pool with the target ligand and a binding ion to form target-aptamer complexes; separating unbound aptamer molecules from the target-aptamer complexes; contacting the target-aptamer complexes with a chelating agent having affinity for the binding ion wherein a switchable aptamer specific to said target is released from the target-aptamer complexes; and isolating the switchable aptamer released in the preceding step.

  • Patent number: 10107846
    Abstract: A method and apparatus for generating high-order harmonics in a solid-state medium comprising integrated semiconductor devices and electronics. The high-order harmonics interact with and are modified by the internal electric field associated with the operation of the integrated semiconductor devices and electronics. Measurement of the high-order harmonics after modification by the internal electric fields amounts to high resolution (temporal and spatial) dynamic imaging of the internal electric fields associated with the integrated semiconductor devices and electronics.

  • Patent number: 10037222
    Abstract: Technologies are generally provided to virtualize hardware acceleration. In some examples, a coprovisor component may be configured to multiplex multiple domains' requests to access a hardware accelerator such as a field programmable gate array (FPGA), an application specific integrated circuit (ASIC), or a comparable accelerator in a paravirtualized environment. Hyper-requesting may be employed for hardware acceleration virtualization, where a hardware acceleration module concurrently loads a portion of data of a request for a first accelerator application and a portion of data of another request for a second accelerator application and simultaneously processes the two portions of data. Directly situated on a device driver layer, the coprovisor may schedule portions of access requests to the hardware accelerator at the same time through direct memory access (DMA) context switching.
