Abstract: Disclosed are a method for manufacturing an anticorrosive thin film resistor and a structure thereof, which includes a thin film resistor and a protection layer formed on the thin film resistor. The method uses one of silicon (Si) or tantalum (Ta) to serve as a film coating target and, during a process of reactive sputtering, mixes reactive oxygen or nitrogen with a discharge gas so as to coat a thin film on the thin film resistor with the operation temperature of the reactive sputtering process controlled between 100° C.-500° C. As such, the film coating target is passivated to form an anticorrosive protection layer having a thickness of at least 1 ?m to prevent change of electrical property of the resistor resulting from electrolytic corrosion.

Abstract: A safety-critical smart battery management system with the capability of charging single battery cells and discharging battery pack, which comprises smart battery pack, a smart battery charging module and a smart battery discharging module. In the smart battery pack, many cells in a battery group are charged separately at a time. The smart battery discharging module is used to discharge the smart battery pack, so as to achieve the efficacy of a promoted charging efficiency, an increased overall energy source efficiency, and a prolonged battery lifetime. The mechanism has plugging and automatic electric disconnection. Whenever a safety issue or a not-in-use state presents, the smart battery discharging module may be automatically separated with a load. The cells may be avoided from a self-discharging, which successively causes fire catching and thus an explosion and adversely affects a lifetime of the cells, thereby promoting a safety and reliability of the battery system.

Abstract: A request handler may receive transaction requests for transactions to be executed using data of a database, and may classify a first transaction request of the transaction requests as a simple transaction request, and a second transaction request of the transaction requests as a complex transaction request. A key-value store engine may execute a first transaction satisfying the first transaction request, using a key-value store of pre-calculated results determined prior to receipt of the first transaction request, and based on the data, and may update a key-value delta reflecting a change, if any, of the key-value store caused by the first transaction. A relational store engine may cause the at least one processor to execute a second transaction satisfying the second transaction request, using a relational store including a subset of the data, and may update a relational delta reflecting a change, if any, of the relational store caused by the second transaction.
