Abstract: A blockchain-based room inventory management system includes a property management system (PMS) module and an intermediate server system. The PMS module may be under a hotel's direct control. The intermediate server system communicates with at least one online travel agency (OTA) module and/or at least one booking engine using Ethereum-based smart contracts for confirming and processing a room reservation event. If the room reservation event is confirmed to be a successful transaction, the intermediate server system also updates the successful transaction into the PMS module and a blockchain formed by multiple node servers. The blockchain contains multiple blocks arranged in a chronological order for distinguishing successful transactions of different moments. In this way, each successful transaction is prevented from wrongly preceded by a later successful transaction. And the room inventory management system neutralizes an overbooking issue accordingly.

Abstract: A probe head includes an upper pin holder and a lower pin holder coupled to the upper pin holder. A pin arrangement space is defined between the upper pin holder and the lower pin holder. A conductive film is disposed between the upper pin holder and the lower pin holder. A plurality of probe pins penetrates through the upper pin holder, the conductor film and the lower pin holder, and extends outwardly from a bottom surface of the lower pin holder.

Abstract: A test kit for testing a device under test (DUT) includes a socket structure for containing the DUT, and a plunger assembly detachably coupled with the socket structure. The plunger assembly includes a multi-layered structure having at least an interposer substrate sandwiched by a top socket and a nest.

Abstract: A method for profit sharing is provided. The method includes deciding a first sharing rate according to a first event information and a first category information; obtaining a first sharing amount according to the first sharing rate and a first shared profit of the first category information; deciding a second sharing rate according to a second event information and a second category information; obtaining a second sharing amount according to the second sharing rate and a second shared profit of the second category information; deciding a total sharing amount by summing up the first sharing amount and the second sharing amount; and returning the total sharing amount in response to receiving a request from a user device.

Abstract: An information delivery method for transferring fund is provided. The information delivery method includes receiving payment information, determining whether a transfer condition is met according to the payment information, in response to determining that the transfer condition is met, obtaining source account information of a source entity and destination account information of a destination entity in the payment information, determining a transfer path according to the source account information of the source entity and the destination account information of the destination entity, and transmitting the payment information from the source entity to the destination entity according to the transfer path.

Abstract: A wireless test system includes a load board having an upper surface and a lower surface. The load board has a testing antenna disposed on the load board. A socket for receiving a device under test (DUT) having an antenna structure therein is disposed on the upper surface of the load board. The antenna structure is aligned with the testing antenna. The wireless test system further includes a handler for picking up and delivering the DUT to the socket. The handler has a clamp for holding and pressing the DUT. The clamp is grounded during testing and functions as a ground reflector that reflects and reverses radiation pattern of the DUT from an upward direction to a downward direction toward the testing antenna.

Abstract: A method of item management, comprises establishing a blockchain network comprising at least a wallet, which is corresponding to at least a container; issuing a first token corresponding to a plurality of items to a first wallet of the at least a wallet in the blockchain network when the plurality of items is added to a first container of the at least a container; and modifying a status of the first token according to a status of the plurality of items in the first container.

Abstract: A method for determining integrity of information of an object, comprises generating a first data corresponding to the information of the object and generating a first representative data corresponding to the first data; storing the first data to a database, and adding the first representative data into a first block of a blockchain; reading a second data from the database in response to a command for retrieving the first data from the database; using the first block to indicate whether the second data is identical to the first data.

Abstract: A system for managing topology of virtual machines (VMs) includes a base-information database, an information register processing unit, and a topology information database. The base-information database records internal information of all VMs of a cloud system. The information register processing unit monitors the base-information database for updating the internal information of the VMs to the topology information database. The topology information database mainly records a mapping between an alias name and a hostname of each VM, and also records a mapping between the hostname and IP address of each VM. The alias name of each VM is defined in accordance with the task assigned to the VM in the cloud system.

Abstract: Playback control methods and systems are provided. At least one picture is obtained. The picture corresponds to a frame, and the picture includes a first region and a second region adjacent to the first region. It is determined whether at least one pixel in the first region has a predefined color, and whether at least one pixel in the second region has the predefined color. When the pixel in the first region has the predefined color and the pixel in the second region does not have the predefined color, the first region is removed, and the second region is enlarged to cover an original position of the first region. The enlarged second region is then played back via an anamorphic lens.
