  • Publication number: 20190382037
    Abstract: A railway vehicle parking brake that can provide the appropriate tension to the braking system using a motor, a brake chain drum interconnected to the motor to take up or release a brake chain, a load arm deflects in response to tension in the brake chain, and a switch that is closed by the load arm when it deflects. A movable sheave interconnects the brake chain and the load arm and is positioned between the brake chain drum and a fixed sheave over which the brake chain is looped. A control method considers the position of the first switch to determine whether to the motor off when applying the brakes and the amount of current being drawn by the motor to determine whether to the motor off because of a system failure.

  • Patent number: 10474781
    Abstract: Layout simulation and verification of a semiconductor chip can require extensive design rule checking (DRC) and design rules for manufacturing (DRM) analysis of the design in order to ensure proper operation. DRC and DRM can be expensive in terms of computational time and resource usage. To mitigate some of the cost, a virtual layer can be constructed for a cell instance identified in the semiconductor design. Shapes including rectangles and polygons can be determined which traverse the cell instance and are from other hierarchical layers of the design. The shapes can be combined to generate a virtual layer used for simulation, validation, DRC, DRM, etc. The virtual layer can be augmented with traversing shape information from other instances of the cell. The rectangles, polygons, and complex polygons can be combined to simplify the virtual layer. Multiple virtual layers can be generated for the simulation and validation processes.

  • Publication number: 20190332669
    Abstract: A conversation system allowing for complex, open-ended conversations with users and method of its operation are disclosed. An example method includes identifying a conversation and a user, encoding the user's input message and finding codes in other texts, generating responses, and selecting an appropriate response, and sending the selected response to the user. The conversation system utilizes various methods, scoring, codes, and the like to find the appropriate responses. Example methods also include steps for sending short sentences representing action, or sending a “thought” or “daydream” to the user that reveals the emotional state of the conversation system with respect to the user, and steps for changing that emotional state. The system avoids reliance on artificial neural networks and keeps track of the context of a conversation by saving conversation codes in a database.

  • Patent number: 10308431
    Abstract: A flexible composite conveyor belt, such as for use as a belt wrapper in overlying combination with a metal belt in cooking or heating operations. The belt includes a protrusion attached to a flexible substrate. The protrusion includes an engagement surface adapted to secure the protrusion to a portion of the underlying metal belt to drive the belt at a same speed as the conveyor belt. Protrusions on opposing ends of the belt negate the need for conventional lacing in securing the ends of the belt together.

  • Patent number: 10311190
    Abstract: Identifying the interactions of a selected cell across a hierarchical diagram of an integrated circuit and mapping the ways in which the cell can interact with other structures in the hierarchy reduces the computational load for design rule checking (DRC) and design rules for manufacturing (DRM). To this end, a cell and multiple instances of the cell are identified within hierarchical design levels of the chip. The interactions between the cell and other cells within the hierarchy are subtracted from the cell boundary, and the results of the subtracting are merged in the cell boundary. By subtracting the results of the merging, identical interactions are identified across the multiple instances of the cell. The results of the subtracting are used to generate a virtual hierarchical layer identical (VHLi) which aids in the simulation and verification of the chip.

  • Patent number: 10303837
    Abstract: Semiconductor designs are large and complex, typically consisting of numerous circuits called cells. To handle complexity, hierarchical structures are imposed on the semiconductor design to help accomplish analysis, simulation, verification, and so on. The hierarchical structures define architecture, behavior, function, structure, etc. of the semiconductor design. Virtual cells are constructed to compress cell geometries and ease the various design tasks. A cell and multiple instances of the cell are identified within the semiconductor design and the virtual hierarchical levels describing the design. Virtual hierarchical layer (VHL) data based on the cell is loaded. A virtual cell model representative of the cell is obtained. Interactions between cell data and VHL data are determined, and relevant portions of shapes are selected. Data within the virtual cell model is reduced based on the determined interactions.

  • Patent number: 10184819
    Abstract: A container having a flow end with an associated hole in a surface that matches a cutout in a cover that is inserted in the flow end. Rotation of the cover with the container aligns the hole with the cutout in the cover; to allow fluid flow when the system is placed downwards into a liquid body. When the liquid level in the container matches that in the liquid body, a base is inserted within a resting end of the container thereby restricting liquid flow in or out of the system. As the container is removed from the liquid, the cover at the flow end is twisted so that the hole in the container is covered thereby creating a closed system, blocking any fluid movement. The system is placed on the resting base and stored to compare at a later time with the Liquid Containment System.

  • Publication number: 20180345069
    Abstract: A dynamic belt-tensioning apparatus for a treadmill includes a base having a first end and a second end spaced from the first end. A foot-striking platform is movably supported by the base so as to allow vertical movement of the platform during operation of the treadmill. A drive belt has a fixed circumference and is positioned above a top portion of the platform. A drive roller is pivotally mounted adjacent to the first end of the base and engages the drive belt. A tensioning roller is pivotally mounted to the base and is capable of a range of movement to provide substantially constant tension to the drive belt in response vertical movement of the platform.
