  • Patent number: 11914432
    Abstract: A portable electronic device including a first body, a second body, a pivot element, a heat source, a first flexible heat conductive element, and a flip cover is provided. The pivot element is connected to the second body, and the second body is pivotally connected to the first body through the pivot element. The heat source is disposed in the first body. The first flexible heat conductive element is thermally coupled to the heat source and extends toward the pivot element from the heat source. The first flexible heat conductive element passes through the pivot element and extends into the inside of the second body and is thus thermally coupled to the second body. The flip cover is pivotally connected to the first body and located on a moving path of the pivot element.

  • Patent number: 10372728
    Abstract: Systems, methods, and other embodiments are disclosed for identifying features within point cloud data. In one embodiment, point cloud data is read which represents multiple points of at least one point cloud in a multi-dimensional space. Each point in the point cloud data is defined by an attribute value quantifying an attribute of the point and a set of coordinates specifying a location of the point in the multi-dimensional space. The set of coordinates for each point is transformed into a space-filling distance value representing a distance along a space-filling curve. The points are sorted according to the space-filling distance values to generate a sorted order of the points. The points are traversed in the sorted order and output data points are derived, while traversing the points, based on a specified feature criterion. The output data points identify a feature within the at least one point cloud.

  • Patent number: 10122583
    Abstract: Systems, methods, and other embodiments associated with aggregated network modeling with component network aggregation are described. In one embodiment, a method for modeling an aggregated network includes storing a first set of nodes associated with a first network and a first set of links associated with the first network, wherein each link in the first set of links connects a pair of nodes in the first set of nodes. A second set of nodes associated with a second network and a second set of links associated with the second network are also stored. A set of transfer links is stored. Each transfer link connects a node in the first network to a node in the second network. Metadata defines the aggregated network as the first set of nodes, the first set of links, the second set of nodes, the second set of links, and the set of transfer links.

  • Patent number: 8605608
    Abstract: Systems, methods, and other embodiments associated with generating a network buffer are provided. A network data model is input that includes a set of network elements, such as nodes and links, and respective costs associated with respective network elements. A center network element around which to generate the network buffer and an offset cost to define a boundary of the network buffer are also input. A network buffer is generated by determining a buffer coverage and cost. The network buffer is made up of a set of buffer network elements located within the offset cost with respect to the center network element. The cost for each buffer network element is determined as the cost associated with travelling a path with minimum cost from the center network element to the corresponding buffer network element. The buffer coverage and costs are output for subsequent analysis.

  • Patent number: 8429199
    Abstract: Systems, methodologies, media, and other embodiments associated with load on demand network analysis are described. One method embodiment includes accessing a network analysis request and data associated with a set of network partitions associated with a network. The request describes a function to be performed on the network. A set of partitions subdivides the network and a data model stores data describing the network and its partitions. Thus, the example method may include identifying a member of the set of network partitions associated with the network analysis request and selectively loading data associated that member. The method may then perform the network analysis function on the data associated with the member rather than on data describing the entire network.

  • Patent number: 7454428
    Abstract: A shareable application program interface (API) and network data model infrastructure which is used in combination with a relational database to provide data storage and processing functions for network data. The network data model is stored in relational tables that describe a set of nodes and links forming a network wherein each node represents an object of interest and each link represents a relationship between two nodes. A generic node table contains a row describing each node in the network, and a generic link table contains row data describing each link. In addition, a path table whose contents are commonly generated by network analysis procedures contains rows which describe corresponding paths each consisting of an alternating sequence of nodes and links. The sequence of links in each path are identified in a separate path-link table.

  • Publication number: 20070130133
    Abstract: A technique used with PL/SQL routines that are wrappers for Java routines which permits a PL/SQL wrapper routine to supply a Java class to the Java routine executed by the wrapper routine. The invocation of the wrapper routine includes a parameter value that specifies the class. The relational database system in which the PL/SQL routine is being executed includes a row source for a row that relates the parameter value to a definition for the class that is to be supplied. When the PL/SQL routine is executed, the PL/SQL routine uses the parameter value to query the row source and provides the class definition returned by the query to the Java routine. The technique is employed in a network analysis API that is made up of PL/SQL wrapper routines to supply classes defining network constraints to the Java routines executed by the wrapper routines.

  • Patent number: 5243241
    Abstract: A fine tracking miniature galvanometer actuator is used as a fine tracking positioner for a read/write head in the optical disk drive of an information storage and/or retrieval system. An efficient magnetic circuit is used in conjunction with a small and lightweight rotor design which offers high performance characteristics in terms of frequency response and sensitivity. No mechanical springs or torsion bars are necessary to maintain the rotor in a neutral or zero position. The present invention is also useful in other systems using electro-optical transducers including reflecting-type galvanometer recording systems used for producing variable-area sound tracks .

  • Patent number: 4582437
    Abstract: The high speed print pin actuator disclosed herein is constructed as two sub-assemblies, a U-shaped fixed magnet structure and an armature sub-assembly. One leg of the U-shaped structure constitutes a coil core and the other includes a permanent magnet and a keeper plate, the ends of the keeper and the core being finished to a common plane. The armature assembly includes a flux return bridge structure which extends from the keeper to a region adjacent the end of the coil core and which is bifurcated to receive an armature which is selectively attracted to the coil core. The armature is carried on a spring which is, in turn, mounted on the bridge structure. With the spring in a deflected position, the armature is finished to a common surface with the portion of the bridge which mates with the magnet structure. Accordingly, assembly of the armature sub-assembly with the U-shaped fixed magnet structure is facilitated and accurate parallelism of the armature and pole piece is provided.
