Abstract: A network node includes at least one processor, at least one memory, and at least one network interface. The network node is configured to be within a plurality of network nodes communicatively coupled in a peer-to-peer network of network nodes implementing a distributed ledger. The network node is configured to be communicatively coupled to at least one remotely located computing device through the at least one network interface. The at least one processor is configured to determine a split ratio for a new split of security tokens held in at least one address of the distributed ledger. The at least one processor is also configured to store an indication of the split ratio without updating token balances for all of the at least one address in a list of addresses holding at least one of the security tokens.

Abstract: A network node in a peer-to-peer network of nodes includes at least one processor, at least one memory, and at least one network interface. The at least one processor is configured to receive a request to transfer a security token and execute a plurality of compliance rules associated with the security token. At least one of the compliance rules is implemented using at least one smart contract. The at least one smart contract references a global registry. The at least one processor is also configured to transfer the security token based on the execution of the compliance rules. The global registry includes personally identifiable information (PII) hash(es) for each of at least one investor associated with the transfer of the security token. The hashes are committed to the distributed ledger and updated when PII of a respective one of the at least one investor changes.

Abstract: A multi-model data store comprises an enrichment catalog and an enrichment memory graph. Raw data from a source raw datastore is enriched based on an enrichment function. Enriched data is stored in graph nodes with edge associations indicating the enrichment type and confidence level. The enriched data is also stored in the enrichment catalog with full breadcrumb provenance and lineage identifying, with cataloged enrichment steps, down to a record and field in the source raw datastore. Additional enriched values and associations between graph nodes can be entered in the graph by a user. Queries to the multi-model database begin in the graph and continue to the enrichment catalog. Query results include the full sequential chain of enrichments to source raw data records and fields, and may include dynamically generated virtual enrichment catalog records that link search values not found in the enrichment catalog to enrichment catalog records via the graph.

Abstract: Systems and methods provide a conversational website or native application. The conversational website or native application includes an interface that enables a network device to exchange one or more messages with a bot or a terminal device (operated by a live agent) during a communication session. The interface may include a communication area (e.g., a portion of the screen) and a dynamic content area (e.g., another portion of the screen). The content of a message received from the network device may be used to select dynamic content to display in the dynamic content area. Dynamic updating of content displayed in the dynamic content area occurs continuously as messages are exchanged during the communication session.

Abstract: The present disclosure refers to a housing element for a drug delivery device. The housing element comprises longitudinal axis and defines an interior space for receiving components of a drive mechanism of the drug delivery device and at least a portion of a cartridge of the drug delivery device. The housing element comprises an engagement feature for axially constraining the housing element to a cartridge holder of the drug delivery device. In order to constrain the cartridge in the housing element, it further comprises at least one crush web protruding radially inwards into the interior space. The at least one crush web is angled relative to the longitudinal axis of the housing element by at least 3° such that when the cartridge is introduced into the interior space the at least one crush web folds radially outwards.

Abstract: A needle hub for a drug delivery device includes a needle holder and a needle attached to the needle holder, a needle actuation assembly configured to move the needle holder from a retracted position, to an insertion position, and back to the retracted position, and a pressure interlock comprising an inlet configured to be in fluid communication with a fluid source, an outlet in fluid communication with the needle, and a lock member. The lock member having a first position where the lock member prevents actuation of the needle actuation assembly and a second position where the lock member allows actuation of the needle actuation assembly. The lock member is moved from the first position to the second position based on a pressure within the pressure interlock.

Abstract: An approach to identifying poorly performing data storage devices (DSDs) in a data storage system, such as hard disk drives (HDDs) and/or solid-state drives (SSDs), involves retrieving and evaluating a respective set of log pages, such as SCSI Log Sense counters, from each of multiple DSDs. Based on each respective set of log pages, a value for a Quality of Service (QoS) metric is determined for each respective DSD, where each QoS value represents an average percentage of bytes processed without the respective DSD performing an autonomous error correction. In response to a particular DSD reaching a predetermined threshold QoS value, an in-situ repair may be determined for the particular DSD or the particular DSD may be added to a list of candidate DSDs for further examination, which may include an FRPH examination for suitably configured DSDs.

Abstract: The present invention refers to a drug delivery device comprising a housing (5, 10) with an opening (12), a piston rod (11) having a proximal end and a distal end, at least a portion with an interface (14) adapted to engage the opening (12) for guiding the piston rod (11) during a distal or proximal movement of the piston rod (11) relative to the housing (5, 10) and at least one first attachment element (15) located at the distal end, and a bearing (16) with at least one second attachment element (17, 18) for rotatable attachment of the bearing (16) at the distal end of the piston rod (11). The at least one first attachment element (15) and/or the at least one second attachment element (17, 18) is elastically deformable in a radial direction for snap engagement of the piston rod (11) and the bearing (5, 10).

Abstract: An approach to identifying problematic data storage devices, such as hard disk drives (HDDs), in a data storage system involves retrieving and evaluating a respective recovery log, such as a media error section of a device status log, from each of multiple HDDs. Based on each recovery log, a value for a Full Recoveries Per Hour (FRPH) metric is determined for each read-write head of each respective HDD. Generally, the FRPH metric characterizes the amount of time a head has spent performing recovery operations. In response to a particular head FRPH reaching a pre-determined threshold value, an in-situ repair can be determined for the HDD in which the head operates. Similarly, in the context of solid-state drives (SSDs), a latency metric is determinable based on time spent waiting on resolving input/output (IO) request collisions, on which an in-situ repair can be based.
