Abstract: According to some embodiments, methods and systems may provide request governance in a multi-tenancy cloud computing environment of an enterprise. A default cluster and a quarantine cluster may each execute application servers, and an automated quarantine enterprise configuration may store automatically managed tenant identifiers. An automated quarantine manager may automatically determine which tenant identifiers are stored in the automated quarantine enterprise configuration (e.g., based on a dynamic sliding time window). The automated quarantine manager may receive a tenant request from a client and arrange for the received tenant request to be executed by an application server in either the default cluster or the quarantine cluster in accordance with an associated tenant identifier in the automated quarantine enterprise configuration.

Abstract: A single piece light pipe is designed to provide dual-field, multi-color, multi-directional illumination. The light pipe is combined with a single PCB having a plurality of LEDs to create a compact illuminator that can selectively provide dark field and bright field with red, green, blue color, broad spectrum, or combination of any color in horizontal, vertical, diagonal, or combination of any direction. The single piece light pipe is compact in size and light in weight. The non-closed form option not only can further reduce the weight but also can allow arrange opening area clearance for: (1) visual aiming and alignment in application, especially for hand held application; (2) reducing illumination crosstalk to unwanted directions; and for (3) mechanical integration. The improvements allow the illuminator to read direct product marking (DPM) type of barcodes.

In one embodiment, CID is determined between two points residing within an object surface. In a second embodiment, a CID is determined between groups of points.

Abstract: Blockchains operate as decentralized, self-regulating systems that involve contributions from hundreds of thousands of participants who work on the verification and authentication of transactions occurring on the blockchain. The consensus mechanism within such a system provides the set of rules that determine the legitimacy of contributions made by the various participants of the blockchain. The consensus mechanism should not only be tolerant of faults but also have low latency in establishing consensus. Prior art solutions either could tolerate at most (n+1)/5 faults reaching consensus or execution of three or more communication steps to provide tolerance of arbitrary (Byzantine) faults or cannot guarantee strong safety property for an honest primary. To improve the speed of the consensus mechanism the inventors have established a BFT consensus protocol that operates with just two communication steps.
