  • Patent number: 12039528
    Abstract: There may be provided a computer-implemented method. It may be implemented using a blockchain network such as, for example, the Bitcoin network. The computer-implemented method includes: i) receiving, at a node in a blockchain network, a first transaction associated with a digital asset, the first transaction including a first script that specifies a set of constraints on a second transaction to transfer control of the digital asset, the set of constraints including a constraint that a set of data obtained by the node includes information obtained from a blockchain associated with the blockchain network; ii) obtaining the second transaction, the second transaction including a second script that, as a result of being executed, causes the node to obtain the set of data; and iii) validating the second transaction by executing the first script and the second script.

  • Patent number: 10241685
    Abstract: Implementations of the present disclosure involve a system and/or method for managing a storage system and, more particularly, for externally managing input/output (I/O) requests to a storage device to avoid large delays in servicing the I/O requests. The management system may maintain I/O request queues for one or more of the storage devices associated with the system. The system may calculate a difference between an order value of the I/O request at the top of the queue and the bottom of the queue for the storage devices. If the calculated difference is above a threshold value, new I/O requests for the storage device are not added to the queue or transmitted to the storage device. In this manner, the management system may force the storage device to service an I/O request that has been stored in the queue for some time without being serviced.

The electronic control unit includes a transmission controlling means which sets a signal line connected to the sensor unit, which is a destination of communication data, to a first state, sets the signal line connected to the sensor unit, which is not the destination, to a second state, and transmits the communication data to the destination via a communication line. The sensor unit includes a reception controlling means which determines a state of the signal line connecting a sensor to the electronic control unit. When determining that the signal line of the sensor unit is in the first state, the reception controlling means receives the communication data and performs a predetermined process. When determining that the signal line is in the second state, the reception controlling means discards the communication data.

  • Patent number: 7716406
    Abstract: Embodiments of the present invention provide a system and method for handling persistent reservations. More particularly, according to one embodiment of the present invention, a routing device that routes commands from multiple initiators to a target device can assert reservations for the initiators using its own reservation key rather than a reservation key provided by an initiator. The routing device can further maintain a registry of keys for multiple initiators that access the target device through the routing device. For a persistent reservation command received using a persistent reservation key in the registry, the routing device can forward the command to the target device server using the routing device's key. Thus, reservations for the multiple initiators will be held using the routing device's key. For persistent reservation commands received from initiators registered with the routing device, the routing device can handle conflict resolution and other persistent reservation processing.

  • Patent number: 6545586
    Abstract: A theatre system operating in compliance with the DMX512 protocol is also able to support remote channel assignment of the various theatre devices included therein as well as other auxiliary operating modes by establishing a device hierarchy based on unique ID numbers assigned to the theatre devices when DMX communication is inactive. The theatre devices communicate with each other bi-directionally to establish a device hierarchy. Each theatre device has a pre-assigned unique device identification number, and a hierarchy is established based on these unique ID numbers. One way to establish a hierarchy is to create a list of the unique device identification numbers of the bi-directional theatre devices in the system, and then determine the position of each theatre device on the list. The list may be assembled by one of the bi-directional theatre devices and broadcast to all when completed, or each bi-directional theatre device may itself assemble a complete list.
