Abstract: Embodiments include hardware and software resources of a distributed computing system for routing user data traffic to computing resources organized using a shuffle sharding arrangement. Layer 3 (L3) network load balancers proxy or route user data traffic requests to layer 4 (L4) transport load balancers. A L4 transport load balancer proxies and routes the requests to certain ingress cells that are assigned or mapped to the hosted computing services of the user requests according to proxy or routing functions and mapping data. The assignments between cells and computing services may be implemented by a cell manager program when onboarding the computing services in accordance with the shuffle sharding arrangement and configuration. The transport load-balancer may impose and enforce the shuffle sharding by routing user data to ingress cells assigned to the computing services using previously determined mappings data stored in a mappings database (or data file).

Abstract: A trading appliance for an electronic trading system comprises a keypad into which is integrated a computer which communicates between the keypad and the trading system. The keypad has keys for entry of trade related data into the trading system. A retractable keyboard has keys for entry of non-trade related data into the trading system and may be retracted to a position within the keypad housing. A mouse is provided on the keypad. A display monitor may be connected the keypad for display of trading data received from the keypad and the trading system. A portion of the keypad, and an associated circuit boards may be detached and replaced by a keypad portion appropriate for trading a different instrument or on a different market.

Abstract: The method for reducing status reporting in a wireless communication system (100), such as a code division multiple access wireless communication system is described. Wireless communication system (100) includes a mobile switching center (202), a base station controller (204), and a plurality of base transceiver stations (240-242). The method includes wireless communication system (100) receiving a mobile communication signal (115) from a mobile station (220), and based on the mobile communication signal (115), invoking delivery of an information element (230) to base station controller (204). The method further includes, based on information element (230), selectively forwarding by base station controller (204) a status message to mobile switching center (202). In addition, the method includes acknowledging, by base station controller (204), successful receipt of information element (230).

Abstract: Presented is a tool adapted for use in rupturing the surface of smooth concrete so as to provide a roughened surface. This process is commonly known as "scarifying" concrete. The tool comprises a bit adapted to be mounted in a conventional roto-hammer or other type actuating mechanism that provides a reciprocating and/or rotating motion, the bit being provided with a multiplicity of carbide tips which are driven repeatedly into the concrete surface to effect scarifying thereof.
