  • Patent number: 11411728
    Abstract: The technology disclosed herein provides a proof-of-work key wrapping system that uses key fragments to cryptographically control access to data. An example method may include: encrypting a first cryptographic key to produce a wrapped key, wherein the first cryptographic key enables a computing device to access content; splitting a second cryptographic key into a plurality of key fragments, wherein the second cryptographic key is for decrypting the wrapped key; selecting a set of cryptographic attributes for deriving at least one of the plurality of key fragments, wherein the set of cryptographic attributes are selected in view of a characteristic of the computing device; and providing the wrapped key and the set of cryptographic attributes to the computing device, the set of cryptographic attributes facilitating determination of the second cryptographic key.

  • Publication number: 20160277544
    Abstract: An interface can be designed that efficiently constructs descriptors for streams of protocol data units (PDUs) and provides coherent views of the PDUs and the PDU stream for a requesting application regardless of location within a buffer pool for PDUs. The interface creates a descriptor for each PDU written into the buffer pool and links the descriptors in accordance with the appropriate order of the corresponding PDUs. The interface can create PDU descriptors hierarchically. For instance, a PDU descriptor for a PDU of a layer N protocol can refer to one or more PDU descriptors of a layer N?1 protocol.

  • Patent number: 9238264
    Abstract: A description is provided of a mixture which is preparable by allowing the reaction of a premixture of (av), methanesulfonic acid (bv), one or more esters of one or more phosphorous-oxygen acids and (cv) one or more silanes. The invention also concerns the use of said mixtures as additives for the polyisocyanate component of a two-component binding agent system for preparation of a polyurethane resin. The invention further concerns a solution containing polyisocyanate for use as a component of a molding material binding agent system, and the use of a solution containing polyisocyanate as the polyisocyanate component of a two-component binding agent system for preparation of a polyurethane resin and corresponding two-component binding agent systems for preparation of a polyurethane resin.

  • Publication number: 20130320652
    Abstract: An internal deployable vehicle panel assembly includes an inner panel, an outer panel and a deployable energy absorber. The inner panel includes a first mounting structure that movably couples the inner panel to a vehicle component to move between a closed position to cover an access opening to a vehicle storage compartment and an open position to reveal the access opening. The outer panel includes a second mounting structure that is removably coupled to a third mounting structure of the inner panel. The deployable energy absorber is disposed between the inner and outer panels in an undeployed state. The deployable energy absorber is free from fixed attachment to the outer panel and energizable to a deployed state in which the deployable energy absorber separates the outer panel from the inner panel and displaces the outer panel away from the inner panel.

  • Patent number: 7890234
    Abstract: A vehicle seat pressure sensor includes a light source, a non-fiber optical polymer sheet, a boundary layer and a detection unit. The non-fiber optical polymer sheet is composed of non-woven flexible optical polymer material and has a first surface with a peripheral edge surrounding the first surface. The peripheral edge of the optical polymer sheet is aligned with the light source such that light emitted from the light source projects into the optical polymer sheet through the peripheral edge. The boundary layer is disposed along the first surface of the optical polymer sheet. The detection unit is disposed relative to the optical polymer sheet to detect changes in attenuation of light emitted from the peripheral edge of the optical polymer sheet in response to elastic deformation of the boundary layer and the optical polymer sheet.
