Abstract: A first estimation unit estimates, based on pieces of information on the reception strength acquired by an acquisition unit in a first time period, a location of a transmitter. A first determination unit determines, based on the location of the transmitter estimated by the first estimation unit, an area in which the transmitter is present. A second estimation unit estimates, based on pieces of information on the reception strength acquired in a second time period, the location of the transmitter. A second determination unit determines, based on the location of the transmitter estimated by the second estimation unit, the area in which the transmitter is present. A correction unit corrects, when a determination result by the first determination unit is different from a determination result by the second determination unit, the determination result by the first determination unit to the determination result by the second determination unit.

Abstract: An area determination system includes a decision unit, a calculation unit, and a determination unit. The decision unit decides, based on a strength of a radio signal transmitted from a transmitter and received by a receiver, a location of the transmitter. The calculation unit calculates a presence determination value. The presence determination value is based on a number of times that the location of the transmitter is determined to be in a presence determination region during a presence determination time period. The presence determination region corresponds to a target area. The determination unit, when a presence condition is satisfied, determine that the transmitter is in the target area. The presence condition is that a state where the presence determination value is greater than or equal to a presence threshold continues for a presence determination time.

Abstract: An optical device includes a range finding module. The range finding module includes a first light condenser unit, a light emitting unit and a light receiving unit. The first light condenser unit defines an optical axis and a hole disposed along the optical axis. The first light condenser unit, the light emitting unit and the light receiving unit are sequentially arranged along the optical axis. The light is emitted by the light emitting unit, passes through the hole, reaches an object, is reflected by the object, is converged by the first light condenser unit and is received by the light receiving unit to generate an electrical signal.

Abstract: An example operation may include one or more of receiving a plurality of transactions by an agent node, selecting, by the agent node, transactions from the plurality of the transactions that are the most likely to be conflicting based on common factors, combining, by the agent node, the selected transactions into a batch, and reordering the selected transactions within the batch to increase a success rate.

Abstract: An example operation may include one or more of submitting, by a blockchain client, a transaction proposal to a blockchain network, endorsing, by one or more endorser nodes or peers, the transaction proposal, endorsing comprising updating an in-process world state list, providing one or more composite endorsements, each comprising a base result and a forecasted result corresponding to the transaction proposal, submitting an endorsed transaction in response to the one or more composite endorsements, validating, by a committer node or peer, the endorsed transaction, committing the endorsed transaction to the blockchain network, and removing the committed transaction from the in-process world state list.

Abstract: A sub-printing method for a 3D printer (1) includes following steps: obtaining slicing data (3) of a printing layer by the 3D printer (1) when performing printing; executing a logical segmentation action on the slicing data (3) according to a default segment-template (101) for generating multiple printing blocks (4); labelling each printing block (4) according to a default printing rule for deciding printing orders of the multiple printing blocks (4); controlling the 3D printer (1) to perform multiple sub-printing actions successively according to the printing blocks (4) based on the decided printing orders; and, re-executing above steps before all printing layers of a 3D model are completely printed.

Abstract: A computer implemented method for selecting breakpoints for cross-layer debugging is provided. The method includes receiving code comprising a plurality of layers, and executing a static analysis of the code to obtain a use-definition (UD) chain, alias information, and a parameter mapping for each of the plurality of layers. The method also includes determining a statement of the code that produces one of an error and a failure, and generating a table comprising a plurality of fields including a working statement field, watching variable field, and a watching function field. The method includes adding the determined statement to the working statement field and performing a cross-layer analysis includes identifying at least one used variable and its associated alias as watching variables from the added working statement, searching the code based on the watching variable field. The method includes generating cross-layer suspect code points based on the cross-layer analysis.

Abstract: Flexible utilization of capacity to provide computing services mediated by a service broker. The service broker receives a request from a first party for assistance with a service workload as well as an indication from a second party of a willingness to provide service. The service broker matches the parties with each other based at least in part on the capacity of the second party to service the service workload of the first party, manages offloading of the service workload from first party to the second party, and manages billing of a workload provider (such as the first party or the first party's customer) for the offloading engagement.
