Abstract: A computer-implemented method for a service mesh to simulate and address a situation in which there are several transactions among services with an asynchronous relationship between the services is provided. The computer-implemented method includes identifying that the situation occurs with a response provided to a user upon a user invocation of one of the services, analyzing the situation to determine that the asynchronous relationship between the services caused an error in at least one of the several transactions, recording data of a next user invocation of the one of the services, modifying the data of the next user invocation of the one of the services to correct the error and to thereby generate modified data, simulating an execution of the next user invocation of the service using the modified data and confirming that the modified data corrects the error based on results of the simulating.

Abstract: A system and method facilitating group personalized federated learning are provided. The system may provide a global machine learning model, generated based on federated learning, to communication devices. The system may also receive model parameters from the communication devices based in part on the communication devices determining local training data generated by the communication devices implementing the global machine learning model. The system may also determine, based on the model parameters from the communication devices, groups of the communication devices and may assign a group specific machine learning model(s), among a plurality of group specific machine learning models, to the groups. The plurality of group specific machine learning models may be associated with the global machine learning model.

Abstract: A mobile computing system includes a case and a frame installed into the case. The components of the mobile computing system are affixed to the frame. The frame includes a first section and a second section. The first section is flexibly coupled to the second section by at least one first flexible joint and is not otherwise rigidly coupled to the second section. The frame is fabricated as a single molded piece.

Abstract: A smart card holding member in this exemplary embodiment includes a main member, a connection member, and two resisting members. The connection member is connected to one end of the main member and bends toward the main member. The resisting members bend from opposite sides of the main member and each resisting member includes a locking section for fastening a battery in position. The resisting members are respectively connected to opposite sides of the main member to form an accommodating space for receiving a smart card therein. One part of the smart card is exposed out from the main member to be removed. A portable electronic device employing the smart card holding member is also described.

Abstract: The invention relates to a novel class of ruthenium complexes containing phosphine and hybrid amine ligands, their preparation and use as catalysts in the reduction of simple ketones to alcohols by molecular hydrogenation. The reactivity and enantioselectivity of such complexes in the asymmetric hydrogenation of simple ketones could be enhanced by the addition of some selective additives.

Abstract: A key assembly for an electronic device includes a key and a housing, the key being elastic and including a contact body and an assembly wall integrally formed with the contact body, the contact body has a protrusion formed thereon; and the housing has a shortened wall defining an aperture therein and a bottom wall protruding a column adjacent to the shortened wall. The key is mounted into the housing, the assembly wall is clipped to the column and the shortened wall, and the contact body abuts the shortened wall and the protrusion protrudes out of the aperture.

Abstract: A battery holding structure (100) for holding a battery (3) inside an electronic device includes a housing (1), an elastic sheet (26), and a block (112). The housing defines a battery chamber (10) and includes a top sidewall (11) and a bottom sidewall (15). The elastic sheet is formed on a bottom sidewall. The block is formed on the top sidewall. The elastic sheet is compressed by the battery to be held within the electronic device such that the battery is secured in the battery chamber by the block.

Abstract: An electronic device (20) includes a housing (24) and a rocking key button assembly (200) rockingly assembled to the housing. The housing includes a shaft portion (264) and a blocking board (268). The key button assembly includes a key button (30) having two opposite key portions (312), two elastic retaining members (40), two elastic arms (50) and two triggers (60). The elastic retaining members are retained to the shaft portion. The elastic arms resist against the blocking board. The key portions can rock relative to each other and about the shaft portion, the corresponding one trigger swings relative to the other trigger and about the shaft portion. The corresponding elastic arm is compressed by the blocking board. The elastic retaining members, the elastic arms and the triggers are arranged at the same side of the key button opposite to the two keys.

Abstract: An engaging device for a computer screen in a car, comprises a fixing base fixedly attached in the car, lock block, and a coupling frame attached to the rear side of the computer screen. The lock block is rotatably engages with the fixing base by way of two pivots. The pivots have a function of stagnating the lock block at specific angular position optionally. Both lateral sides of the coupling frame have a locking hole respectively and the lock block at both lateral sides thereof provides an elastic engaging plate therein. The respective elastic engaging plate has a part extending outward through the locking hole. Once the lock block is inserted into the coupling frame, a detachable firm engagement between the lock block and the coupling frame can be reached substantially.

Abstract: A small liquid sample (24) to be tested is contained within an annulus (18) on the upper surface (14) of a substrate (12). In one embodiment, a reagent diffuses into the sample through a membrane (28) in a junction hole (26), the junction hole connecting upper (14) and lower (16) surfaces of the substrate. Optical measuring equipment (70, 72) detects a measurable change in an optical property of the sample. In an alternate embodiment, a flow of gas (30), directed at the small liquid sample (24), causes the sample to flow in a controlled manner over the surface of an electrode (20), disposed on the substrate surface (14). In another alternate embodiment, a special averaging electrode (20) is disposed in a non-homogeneous sample (24). Highly reproducible and accurate hydrodynamic electrochemical studies and analyses of microliter size samples are thus achievable, without the need for moving mechanical parts.
