Publication number: 20160277544Abstract: 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.Type: ApplicationFiled: June 2, 2016Publication date: September 22, 2016Applicant: NETAPP, INC.Inventors: Ardalan Kangarlou Haghighi, John David Strunk

Publication number: 20130320652Abstract: 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.Type: ApplicationFiled: May 30, 2012Publication date: December 5, 2013Applicants: SHAPE CORP., NISSAN NORTH AMERICA, INC.Inventors: David Strunk, Darin Evans
