Abstract: In order to ingest data from an arbitrary source in a set of sources, a computer system accesses predefined configuration instructions. Then, the computer system generates a dynamic data-ingestion pipeline that is compatible with a Hadoop file system based on the predefined configuration instructions. This dynamic data-ingestion pipeline includes a modular arrangement of operators from a set of operators that includes: an extraction operator for extracting the data of interest from the source, a converter operator for transforming the data, and a quality-checker operator for checking the transformed data. Moreover, the computer system receives the data from the source. Next, the computer system processes the data using the dynamic data-ingestion pipeline as the data is received without storing the data in memory for the purpose of subsequent ingestion processing.

Abstract: A feeding device includes a storage mechanism and an adsorbing mechanism. The storage mechanism includes two side plates substantially parallel to each other, two support members slidably coupled between the two side plates, two driving members, and two feeding trays. The driving members are mounted to one of the two side plates and coupled to the corresponding support members. The driving members are configured to drive the two support members to move out of the storage mechanism one at a time. The feeding trays are configured for receiving workpieces and coupled to the corresponding support members.

Abstract: Methods and systems to provide monitoring of operation of threads of a multi-threaded process. In one aspect a reusable thread monitor class is provided that permits each thread desiring monitoring to register with a monitor supervisor. The monitor supervisor may be instantiated in a thread of the process and monitors the operable/inoperable status of the registered threads. The monitor supervisor may be instantiate in any thread of the multi-threaded process or in a specific thread spawned specifically for the monitor supervisor. In a preferred, best presently know mode of practicing the invention, the monitor supervisor is instantiated in the main thread of the process. Monitoring may include “IsAlive” thread status checks, HeartBeat signaling status checks, and/or Polling status check capabilities.
