Abstract: The current document is directed to methods and systems that generate sequences of random numbers. Unlike many currently available random-number generators that continuously measures a physical apparatus or other signal source, the currently disclosed methods and systems employ nondeterministic phenomena that are computationally initiated and computationally accessed within a computer system. The nondeterministic phenomena are often a produced by multiple simultaneously executing, asynchronous threads or other computational entities, with the unpredictability arising from multiple different types and sources of nondeterministic behavior within the computer system. Unlike pseudorandom-number generators, statistics and metrics computed from sequences of random numbers produced by the currently disclosed random-number generators have values close to those expected for a random-selection process.

Abstract: The present invention provides a controller for hydraulic apparatus (100). The controller is configured to determine (310) that an energy return criteria has been met by movement of a first movement component of a first hydraulic actuator. In response thereto, the controller is further configured to select (320) at least one among a plurality of energy control strategies based on at least one operational characteristic of the hydraulic apparatus, and to control (330) the hydraulic apparatus to implement the energy control strategy during movement of the first movable component in such a way as to meet the energy return criteria. The plurality of energy control strategies comprises a first energy control strategy and a second energy control strategy. The at least one operational characteristic of the hydraulic apparatus comprises an indication of an expected energy recovery of one or more of the energy control strategies.

In one example, the passively damped mechanical system includes an end fitting of a strut used to connect a structural element to a payload. The end fitting may include outer and inner cylindrical hubs, with a space between the outer and inner cylindrical hub at least partially filled with a viscoelastic material. In a further example, the passively damped mechanical system includes legs used to connect a structural element to a bracket configured to support a payload. Each leg may include a hollow interior having a lattice structure to add strength and a viscoelastic material to provide passive damping.

Abstract: Each of a plurality of clients encodes events as respective vectors and cooperatively choose a joint key. Each client then encrypts its event vector(s) using the joint key to form secret shares of a fixed value and then sends the encoded, encrypted vectors to a service-providing system that selects pairs of the vectors and determines a comparison value from a reconstruction of the secret shares. When the comparison value meets a predetermined criterion, the service-providing system generates a message indicating similarity between the selected pairs of the vectors. The service providing system thus determines a degree of similarity between the events without requiring knowledge of raw data about the events.

Abstract: There are provided systems and methods for dynamic content security policies using webpage data loaded in webpage element proxies. A service provider may provide online digital computing services, such as electronic transaction processing, account, and the like through online platforms and digital content that may be loaded and served on external webpages. To secure such computing services, webpage data, and digital content from misuse, fraud, or abuse, the service provider may utilize and implement a set of utilities that provide dynamic and secure gateways to internal and/or hosted webpages, webpage content and data, or other digital content of the service provider on external third-party domains, such as websites of known or unknown third parties. This may be done through an iframe or proxy that allows for loading of the digital content on the third-party domain. Access tokens may establish allowable domains for loading the digital content.

Abstract: A system, method, and computer-readable medium are disclosed for providing auditability of a distributed ledger technology (DLT) of de-identified data of entities, stored in the DLT.

Abstract: A compression staple insertion kit includes first and second elongate handles, each including a handle arm having a proximal end and a distal end, distal from the proximal end. A boss extend is outwardly from the distal end. A central longitudinal axis extends between the arms. The handle arms are pivotally attached to each other at the distal ends at a pivot, which extends along the central longitudinal axis. A slider is slidingly attached to the handle. The slider is movable between a staple securing position at the distal end, wherein proximal ends are biased toward each other and a staple release position toward the proximal end, wherein the proximal ends are biased away from each other. A staple is disposed over the bosses.

Abstract: Media, methods, and systems are provided for scheduling a scheduled event within a synchronous multimedia collaboration session within a group-based communication system. A selected start time and a selected time duration may be received such that one or more users are added to the synchronous multimedia collaboration session within a channel of the group-based communication system at or near the selected start time. Upon expiration of the selected time duration, the one or more users may be automatically removed from the synchronous multimedia collaboration session to prevent the scheduled event from extending beyond an allocated time.
