Abstract: A storage platform (100) improves data flow when modifying mirrored volumes. A backup storage component (120A) that receives a service request keeps a copy of change data when redirecting the service request to a primary storage component (120B) that owns the volume that the service request targets. The primary storage (120B) component does not need to return the change data to the backup storage component (120A) when the primary storage component (120B) instructs the backup storage component (120A) to apply the modification request to the backup copy of the volume.

Abstract: Presented here is a system to enable secure communication between a first and a second communicator on a communication channel. The system can use multiple rotating cryptographic keys that are rotating according to a predetermined schedule to encrypt the communication between the first and the second communicator. The system can record the authority associated with the communication channel on a block chain. To determine whether the first and the second communicator have the authority to access the communication channel, the system can compute the authority of the first and the second communicator by checking the block chain from an initial block to a last block. The system can encrypt multiple communications sent via the communication channel using the multiple rotating cryptographic keys and can send the communications via the communication channel.

Abstract: The system obtains a first acyclic graph including multiple nodes and edges connecting the multiple nodes. A process to create a weave of the first acyclic graph produces a matching weave when executed on the first acyclic graph by different computing devices. An addition of a node to the first acyclic graph produces a second acyclic graph. The addition of the node to the first acyclic graph changes the weave of the first acyclic graph. The system obtains a process to reach a global consensus among the multiple computing devices. The process indicates a criterion to satisfy prior to reaching the global consensus and determines whether the multiple computing devices in the network satisfy the criterion. Upon determining that the criterion is satisfied, the system adds a finalize node to the first acyclic graph to obtain a third acyclic graph. A weave of the third acyclic graph cannot change.

Abstract: A conflict-free method of independently governing user authority across one or more devices includes managing user and device authority without the use of a centralized server. The conflict-free method utilizes a conflict-free replicated data type (CRDT) which resolves potential conflicts between merging linear sequences. A first linear sequence at a first electronic device merges with a second linear sequence at a second electronic device. The first linear sequence and the second linear sequence are different due to independent processes performed on devices that are not connected via a network at some point in time. Potential conflicts between the first linear sequence and the second linear sequence are resolved in accordance with CRDTs.

Abstract: In one embodiment, a method includes receiving, from a receiver processor, a transaction authorization request to authorize a transaction associated with a transfer of resources to a receiving entity from a user, the request including publicly routable account credentials of a virtual bank account (VBAN) generated by the receiver processor, the VBAN being associated with the receiving entity, the user, and a stored value balance of an external resource account generated by a receiver financial entity associated with the user, retrieving, from a VBAN database, a transaction resource configuration of the VBAN decoupled from the external resource account, determining whether parameters of the transaction resource configuration are satisfied based on metadata associated with the request, and transmitting, to the external server, a transaction authorization response indicating whether the transaction is authorized to cause the stored value balance to be reduced based on the transfer of resources.

Abstract: Disclosed herein are stabilizer systems that include a base for securing the stabilizer system to a patient table by inserting the base between the patient table and the mattress on the patient table. The stabilizer systems also include a connector that connects a lockable articulating arm to the base. The base protrudes from under the mattress slightly to provide a sturdy and predictable surface to attach the articulating arm of the stabilizer system. The base can then be used to support a lockable articulating arm with a clamp at its distal end for holding an access sheath or delivery system. The connectors attach the articulating arm to the base so that the articulating arm is above the sterile surgical drape to maintain sterility of the articulating arm. The stabilizer systems are advantageous in jugular access procedures.

Abstract: Ray-tracing for terrain mapping is provided. A system of an aerial vehicle can identify points generated from data captured by a sensor of the aerial vehicle. The points can each indicate a respective altitude value of a portion of terrain. The system can determine, based on the altitude values of the points, a threshold altitude of the terrain, and can identify a boundary defined in part based on the threshold altitude of the terrain. The system can generate a terrain map for the terrain based on applying a ray-tracing process to the points. The ray-tracing process can be performed within the boundary, using the points as respective sources and the aerial vehicle as a destination. The system can present a graphical representation of the terrain map in a graphical user interface of the aerial vehicle.

Abstract: A block chain defining authority and access to confidential data may not be encrypted, and the access to the block chain can be regulated by the block chain itself and an access control server operating in an enterprise information technology (IT) environment. To incorporate authority defined in multiple sources, such as the block chain and the access control server, a token can be created containing multiple layers of permissions, i.e. constraints, coming from multiple sources. Each additional permission attenuates the authority granted by the token. When a processor controlling the access to the block chain receives the token, the processor can check the validity of the token and the authority granted by the token to determine whether the requester is authorized to access at least a portion of the block chain.
