Abstract: A dust cover for a hammer work tool, a hammer work tool, and a method of attaching the same are disclosed. The hammer work tool includes a housing, a power cell enclosed inside the housing, a tool member, and a detachable dust cover. When attached, the dust cover prevents particulate matter from entering the housing. When detached, a housing opening uncovered by the dust cover provides access to the power cell for maintenance and repairs. During installation, a housing rim and a locking tab of the hammer work tool are respectively received by a groove and a locking tab receiver of the dust cover. Advantageously, the dust cover is durable, cost effective, and easily attached and detached without the use of additional tools.

Abstract: Aspects of the present disclosure provide systems, methods, and computer-readable storage media that support adaptive machine learning (ML) classification that mitigates effects of catastrophic forgetting while reducing overall resource requirements. To illustrate, a computing device may train first and second ML classifiers based on historical streamed data. The second ML classifier is trained to use continuous learning, and the first ML classifier is not. If data drift of a data stream is below a lower threshold, the data stream is provided as input to the first ML classifier to generate classification output (e.g., predictions). If the data drift is above the lower threshold, dynamic switching occurs and the data stream is provided as input to the second ML classifier instead of the first ML classifier to generate the classifier output. If the data drift is above an upper threshold, operations are performed to train new ML classifiers.

Abstract: A nanoadsorbent based filter is used for purification of fluoride and arsenic contaminated water. 140-150 g low cost (˜10 USD/kg) nanoparticles of gamma alumina of 20-25 mg/g fluoride and 25-30 mg/g arsenic adsorption capacity is incorporated in propylene filter without susceptibility of leaching incorporated nanoparticles in water. The cost of domestic defluoridation device containing low cost nanoalumina incorporated filters/cartridges along with housing, overhead tank, tubing and treated water storage container etc. is of very low cost of around 25 USD/device. The fluoride treatment cost would be <0.5 USD/100 lit for 4-5 mg/l fluoride water after 2-3 regenerations while, the arsenic treatment cost using domestic filtration device would be <0.25 USD/100 lit for 90-100 ?g/l arsenic (III) water.

Abstract: A multi-port power conversion system can have a multi-winding transformer and at least three ports. Each port can be coupled to the multi-winding transformer. Each port can have a semiconductor bridge and a coupling network. For each port, the semiconductor bridge can have two or more levels and can comprise at least two switches. The coupling network for each port can comprise at least one inductor. The semiconductor bridge can be coupled to the multi-winding transformer via the respective coupling network. The multi-port power conversion system can have a multi-active bridge (MAB) architecture that is universally applicable to AC-DC, DC-DC, DC-AC, and AC-AC conversion applications and extendable to any number of ports.

Abstract: A set of multi-winding transformer designs that achieve leakage integration in multi-port power electronics systems is presented. The magnetic design structures are extendable to realize an N-port multi-winding transformer with or without leakage inductance integration, that interfaces different voltage levels (high-voltage and/or low-voltage) with galvanic isolation. The disclosed designs enable: (i) reduced number of discrete magnetic components (ii) high efficiency and high power density; (iii) reduced transformer parasitic capacitances. Furthermore, a global transformer optimization approach that considers magnetizing and leakage inductances, core and winding losses, and parasitic capacitances is presented to systemize the sophisticated multi-winding integrated leakage transformer design process.
