Abstract: Disclosed is a system and several associated methods providing a decentralized fair data marketplace wherein said system keeps time-sensitive (real-time) and location-based data. The system includes a decentralized blockchain for recording participants' registrations, storing transactions such as data production, and sell/buy activities, and ensuring authenticity and privacy of transferred data. Data is gathered through crowdsourcing (data pooling) and data generators are rewarded for willingly contributing datapoints using a dynamic pricing engine designed specifically for time-sensitive location-based datapoints. The set of novelties put together in this invention aims at stimulating a fair and participative data economy where individual contributions, valuation and reward sharing processes are conducted transparently, securely and in a tamperproof manner through use of blockchain, leading to an incentivized and quality data curation.

Abstract: A filter element is provided with a cartridge locating system. The filter element includes a closed end cap and an open end cap with a tubular ring of filter media disposed between the end caps. The filter element includes an annular seal that can seal to round and non-round sealing surfaces and acts to block fluid flow between the open end cap and a pipe assembly in a pressure vessel assembly. A support bar is enclosed by the filter media and has a key. The filter element has a key receptacle to receive the key of the support bar. The user knows that the seal between the filter element and the pipe assembly is fully aligned and engaged when the key from the support bar fully enters the key receptacle of the filter element.
