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: An applicator for an analyte monitoring device may include an actuatable housing having a body defining a cavity therein and having a distal opening and a side opening. A cuff and a shuttle are received within the cavity and are separately translatable relative to the housing body. A base may removable engage the housing body at the distal opening. The housing body, the cuff, the shuttle, and/or the base may be engaged with one another with one or more releasable coupling features. The base may be removed from an engagement with the housing body, causing the cuff and the shuttle to be aligned and positioned in a configuration in which the analyte monitoring device, held by the shuttle, is ready for insertion into the skin.

Abstract: Techniques are described for a data recovery validation test. In examples, a processor receives a command to be included in the validation test that is configured to validate performance of an activity by a server prior to a failure to perform the activity by the server. The processor stores the validation test including the command on a memory device, and prior to the failure of the activity by the server, executes the validation test including the command responsive to an input. The processor receives results of the validation test corresponding to the command and indicating whether the server performed the activity in accordance with a standard for the activity during the validation test. The processor provides the results of the validation test in a user interface.

Abstract: A computing system includes: server; client; broker-dealer database(s) storing personally identifiable information for accounts; and distributed ledger. Server receives request to obtain the personally identifiable information (PII) regarding public information for first account from first user of client. Server determines that a database of the database(s) includes the PII for the first account. Server determines whether the first user has permission to obtain the PII for the first account from the database that includes the PII for the first account. Server receives public information for the first account from distributed ledger when the first user has permission to obtain the PII for the first account from the database that includes the PII for the first account. Server provides the PII regarding the public information to the first user of the client.

Abstract: A spray assembly (110) for a spray head (200) which is arranged, in use, to adjust a spray pattern of fluid includes a spray plate (118) with a plurality of holes (132, 134) therethrough, and a control member (116) rotatable relative to the spray plate (118). In use, the orientation of the spray plate (118) is fixed and rotation of the control member (116) causes fluid to be directed to different groups of the plurality of holes (132, 134) through the spray plate (118). The spray assembly (110) further comprises at least one flow control opening (152) provided in a flow control plate (124) driven by rotation of the control member (116). The flow control opening (152) is arranged, in use, to be moved in response to rotation of the control member (116). The flow control plate (124) has teeth (142) on its outer circumference which interlock with teeth (146) on an outer circumference of an idler gear (148).

Abstract: This disclosure provides a biological sample processing system and methods for processing biological samples. The processing may include one or both of removing wax from wax-embedded biological samples and applying a reagent to biological samples. Aspects of the dewaxing technique and the technique for applying the reagent may be combined to achieve energy efficiencies. Additional efficiency may be achieved by recirculating heated reagent. A hybrid power system may use a source of stored power to supplement external power at times of peak demand. Uniform distribution of liquids across a surface of the biological samples may be achieved by self-leveling using an inclinometer.
