Abstract: A deterministic concurrency control protocol for a blockchain is described. A set of transactions of the blockchain are received at a node. A simulation step and a commit step are performed to process the transactions. A dependency graph is generated comprising the set of transactions and a set of dependencies between the set of transactions, the set of dependencies including one or more read-write dependencies. A backward dangerous structure is identified in the dependency graph. The backward dangerous structure includes a first read-write dependency from a second transaction to a first transaction, and a second read-write dependency from a third transaction to the second transaction. A transaction is aborted based on the identified backward dangerous structure. Each non-aborted transaction is committed. Steps for update reordering, update coalescence, and inter-block parallelism are described.

Abstract: A wallet kit for a mobile electronic device or a mobile electronic device case. The wallet kit includes a wallet with a housing defined by walls of the housing. A wallet pocket configured to hold a card is formed by the walls. A wallet opening is formed in one of the walls and is configured to accept insertion of the card into the wallet pocket. An elastomeric bumper is arranged inside the wallet pocket.

Abstract: The technology generally relates to automatically associating products and services to be advertised in response to a search query and providing sponsored advertisements for output with the search query results on a publisher's website or mobile application. An ad advertiser may create an ad campaign for products without including or identifying keywords associated with the product. Upon receiving a request for an advertisement, an ad server may generate synonyms, or keywords, for the terms in the request. The ad server generated keywords may be used to identify available products that match, or are relevant to, the search query. The ad server may determine a quality of the match and, based on the quality, determine which products are most relevant to the search query. The ad server may solicit bids from the advertisers of the relevant ad campaigns. The winning ads may be returned to the publisher for output.

Abstract: Methods, sample vessels, and instruments are provided for determining antibiotic resistance of a bacterium.

Abstract: Disclosed are embodiments of a video display input assembly including a mechanical rotatable bezel surrounding the video display. The video display input assembly is suitable for use in a gaming terminal, a gaming cabinet or a gaming machine, including as a retrofit to an pre-existing gaming machine. Direction and speed of a manual rotation of the bezel is detected and interpreted. The result may be used to control various aspects of operation of the gaming terminal, gaming cabinet or gaming machine, including providing input for game play. The video display may be updated in real-time to reflect the rotation of the bezel. A motor may be coupled to the rotatable bezel to provide resistance, assistance or operator feedback.

Abstract: A foldable stand for a machine includes a tabletop, a plurality of legs each having one end pivotally mounted to the tabletop such that the legs are turnable relative to the tabletop between an extended position and a received position, a plurality of first locking members each having a body portion movably pivotally mounted to the worktop and a stop portion protruded from the body portion for stopping against the legs so as to lock the legs in the extended position, and a plurality of second locking members respectively mounted in the tabletop for locking the legs in the received position.

Abstract: A laser-guiding coordination device for a drilling machine has a C-base, two laser-line projectors oppositely and adjustably embedded inside the C-base. Each laser-line projector has a first adjuster, a second adjuster perpendicularly and rotatably mounted inside the first adjuster, and a laser generator accommodated inside the second adjuster to generate laser lines. By rotating the first and second adjusters, two laser-lines projected to a workpiece are moved in parallel or rotation to adjust and to define a precise laser mark without need for physically drawing lines on the workpiece.

Abstract: A display device for a circular saw machine includes a flexible ruler whose two ends are connected to a frame fixed to the blade mechanism I the base of the circular saw machine. Two guide rollers are connected to an underside of the worktable and the flexible ruler reeved through the two guide rollers. A window is defined through the worktable of the machine and the flexible ruler goes beneath the window. The flexible ruler moves relative to the window when the blade mechanism is swung and the tilt angle of the blade mechanism can be observed through the window.
