Abstract: An information technology system provided for an instant query includes a dispatcher, a data processor and a storage system. The dispatcher receives data streams from multiple machines and transmits the data streams to a network storage device. In addition, the dispatcher creates a copy of the data streams and transmits the copy to the data processor. The data processor processes the copy according to a predetermined rule to generate an output. The output transmitted to and stored in the storage system is provided for an application to perform the instant query via an interface of the information technology system.

Abstract: Disclosed are a method, a data processing engine, and a system for real-time processing a plurality of continuously-generated data streams. The method for real-time processing the data with different schemas that transmit from heterogeneous relational databases includes steps of identifying categories the data, converting the data, and then storing the data in a non-relational data. Moreover, an architecture is provided together with the system and the method to improve the management of products, product lines or lifecycle such as the feedback of information regarding the performance analysis of an online game, or real-time alerts and recommended actions regarding the yield rate in a manufacturing stage of an industry such as the semiconductor manufacturing industry.

Abstract: An underwater monitoring system with an automatic cleaning capability includes abase, a monitoring device mounted on the base, and a water-flow forming device mounted on the base and operable to form and direct a water flow toward the monitoring device for cleaning the monitoring device. The water-flow forming device includes a pressurizing pump for forming the water flow, such as a laminar flow, and a controller coupled electrically to the pressurizing pump for controlling activation and deactivation of the pressurizing pump.

Abstract: An underwater housing for containing a monitoring device includes a tubular housing body having a front end formed with an inward flange. The inward flange has a rear side surface formed with an annular groove defined by a groove-defining wall. A transparent plate is disposed fixedly within the housing body, and is located behind and adjacent to the inward flange. An annular water seal is disposed within the annular groove and in contact with the inward flange and an outer peripheral portion of the front side surface of the transparent plate so as to establish a watertight seal between the transparent plate and the housing body. An annular cover is disposed fixedly and fittingly within the inward flange, and has a rear end in contact with the front side surface of the transparent plate and in proximity to the water seal for covering the water seal.
