Abstract: Various implementations described herein are directed to a method that identifies a memory instance with multiple tile-cells. The memory instance has memory instance leakage data, and each tile-cell of the multiple tile-cells has tile-cell leakage data. The method subdivides the multiple tile-cells into multiple categories based on a relationship between the memory instance leakage data and the tile-cell leakage data. The method obtains measured leakage data for each tile-cell of the multiple tile-cells by simulating the memory instance based on the memory instance leakage data and the tile-cell leakage data for each category of the multiple categories. The method determines a combined leakage of the memory instance by combining the measured leakage data for each tile-cell of the multiple tile-cells.

Abstract: The technology disclosed herein enables high availability bridging between Layer 2 (L2) networks. In a particular embodiment, a method includes high availability bridge cluster comprising a first bridge node and a second bridge node. The first and second bridge nodes include first and second active bridges and first and second standby bridges, respectively. The method provides, in the first active bridge, bridging network communications between two or more L2 networks. The second standby bridge acts as a failover bridge for the first active bridge. The method further provides generating a failure detection message that incorporates a hardware address of the first bridge node and transferring the failure detection message from the first bridge node to the second bridge node. In the second standby bridge, the method provides receiving the failure detection message and using the hardware address to synchronize bridging information between the first active bridge and the second standby bridge.

Abstract: Described herein are systems, methods, and software to enhance flow operations on a host computing system. In one implementation, a virtual switch on a host identifies a packet from a virtual node. In response to identifying the packet, the virtual switch determines whether the packet corresponds to a cached result action based on traits of the packet. If the packet corresponds to a cached result action, then the virtual switch may process the packet in accordance with the cached result action. In contrast, if the packet does not correspond to a cached result action, then the virtual switch may process the packet in accordance with first flow operations to determine a result action, and cache the result action for use with future packets.

Abstract: This invention provides a system and method for reading and decoding ID features located on a surface of a curved, sloped and/or annular object, such as a tire moving on a conveyor. A plurality of 3D sensors are operatively connected to a vision system processor. The sensors are calibrated by calibration parameters to generate a stitched-together 3D image of a field of view in a common coordinate space. A motion conveyance (e.g. a conveyor) causes the object and the 3D sensors to move in relative motion, and the conveyance provides motion information to the vision system processor. An ID finder locates ID features within a version of the 3D image and a decoder (e.g. an OCR reader) generates data from the ID features. The ID finder can locate a trained portion of the ID and the search for variable code elements at a known orientation relative to the trained portion.

Abstract: Some embodiments provide a method for a network manager that manages multiple managed forwarding elements at a particular datacenter. The method receives a configuration for a bridge between a logical L2 network that spans at least two datacenters and physical L2 networks at one or more of the spanned datacenters. The configuration includes a generic physical network identifier. The method maps the generic physical network identifier to a particular physical L2 network at the particular datacenter. The generic physical network identifier maps to other physical networks at other spanned datacenters. The method provides the configuration to a set of central controllers using an identifier for the particular physical L2 network. The set of central controllers configures a managed forwarding element operating at the particular datacenter to implement the bridge to bridge packets between the logical L2 network and the particular physical L2 network.

Abstract: This invention provides an easy-to-manufacture, easy-to-analyze calibration object which combines measurable and repeatable, but not necessarily accurate, 3D features—such as a two-sided calibration object/target in (e.g.) the form of a frustum, with a pair of accurate and measurable features, more particularly parallel faces separated by a precise specified thickness, so as to provide for simple field calibration of opposite-facing DS sensors. Illustratively, a composite calibration object can be constructed, which includes the two-sided frustum that has been sandblasted and anodized (to provide measurable, repeatable features), with a flange whose above/below parallel surfaces have been ground to a precise specified thickness. The 3D corner positions of the two-sided frustum are used to calibrate the two sensors in X and Y, but cannot establish absolute Z without accurate information about the thickness of the two-sided frustum; the flange provides the absolute Z information.

Abstract: An embodiment of the present invention includes a master camera that may record master metadata regarding an object of interest and communicate the master metadata to a slave camera. The slave camera may zoom, pan, or tilt to isolate and record more detailed image data regarding the object of interest based on the master metadata. In addition, the slave camera may record slave metadata regarding the object of interest. The master and slave metadata may be stored associated with the recorded image data enabling a later search for the object of interest to be expedited. The recorded image data including the object of interest may be identified with greater ease as it may be guided by the master or slave metadata, or a combination thereof. According to embodiments presented herein, processing time for searching and identifying an object of interest may be reduced by enabling a search on the metadata associated with image data, rather than by searching the image data itself.
