  • Patent number: 10545836
    Abstract: Provided are a computer program product, system, and method for hypervisor agnostic interchangeable backup recovery and file level recovery from virtual disks. Data is stored for a first virtual disk that represents data in a first format and metadata for the first virtual disk in a common data format in a storage having a fixed block length. A virtual disk file represents data in a second format that allows variable size blocks. Multiple instances of the fixed block length of blocks of data for the second virtual disk indicated in the virtual disk file are read. Each instance of the read fixed block length of blocks is written to the storage in the common data format with metadata describing the format of the blocks in the second virtual disk, and can be restored to a third virtual disk in the first or second format.

  • Publication number: 20200015920
    Abstract: A multi-layer, super-planar laminate structure can be formed from distinctly patterned layers. The layers in the structure can include at least one rigid layer and at least one flexible layer; the rigid layer includes a plurality of rigid segments, and the flexible layer can extend between the rigid segments to serve as a joint. The layers are then stacked and bonded at selected locations to form a laminate structure with inter-layer bonds, and the laminate structure is flexed at the flexible layer between rigid segments to produce an expanded three-dimensional structure, wherein the layers are joined at the selected bonding locations and separated at other locations. A layer with electrical wiring can be included in the structure for delivering electric current to devices on or in the laminate structure.

  • Publication number: 20190271278
    Abstract: Methods and systems are provided for learning fuel injector error for cylinder groups during a deceleration fuel shut-off (DFSO), where all cylinders of an engine are deactivated, sequentially firing each cylinder of a cylinder group, each cylinder fueled via consecutive first and second fuel pulses of differing fuel pulse width from an injector. Based on a lambda deviation between the first and second pulses, a fuel error for the injector and an air-fuel ratio imbalance for each cylinder is learned. Alternatively or additionally, a difference in crankshaft acceleration between the first and second pulses relative to the expected deviation may be used to learn torque error, and adjust fuel injector error and air-ratio imbalance for each cylinder.

  • Publication number: 20190195244
    Abstract: A liquid suction pump comprising: a drive pipe to receive a liquid drive flow for the pump; a liquid conduit with first and second liquid delivery arms to provide pumped liquid, and a connecting valve arrangement between the arms. First and second pump inlets to the arms have respective first and second one-way inlet valves. The valve arrangement has a valve inlet coupled to the drive pipe and valve outlets coupled to the arms to alternately close off a liquid connection between the valve inlet and respective arms. A compliant element is coupled to the drive pipe. The drive flow oscillates in pressure/flow rate due to alternate switching of the valves. A compliance of the compliant element is such that a geometry of the suction pump in combination with the compliance defines a resonant condition, and the oscillation is at a resonant frequency of the pump.
