Abstract: An anti-polish ring for an internal combustion engine is provided. The anti-polish ring includes an axially extending ring portion that is configured to scrape a top portion of a piston in a cylinder liner. The anti-polish ring is configured to accommodate passage of an intake or exhaust valve thereby. The anti-polish ring may include an alignment feature so that the anti-polish ring is inserted in a predetermined orientation in the cylinder. The anti-polish ring may include a heat shield and/or a seating member.

Abstract: Distributed asset management may be achieved as described herein by representing within a computer database system a collection of distributed assets, and logging within the computer database system time-series data sent from different ones of the distributed assets. Input from authorized users is accepted and stored in the form of tags, each tag being associated with an asset or group of assets. Access is provided to the time-series data or data derived therefrom, and to the tags, by the authorized users. By providing tagging capabilities, diverse requirements of different audiences are supported, and a system can be created wherein the different needs and interests of the audiences are satisfied in such a way as to produce a multiplying beneficial effect. At the same time, complexities are minimized that would otherwise be introduced in order support different taxonomies within a changing heterogeneous environment.

Abstract: A communication processor that uses a group of hardware buffer descriptors and a virtual array of buffer descriptors to control the communication ports of the communication processor. The virtual array of buffer descriptors is a data structure stored in a local memory that contains data fields that are similar to the hardware buffer descriptors of the communication processor. The processor swaps data between the hardware buffer descriptors and the virtual array of buffer descriptors to provide “just in time” storage of control and status information used by the communication ports to transmit and receive data.
