    Abstract: A three-dimensional printing system for fabricating or manufacturing a three-dimensional article includes a support plate, a resin containment structure, an actuator, a light engine, a support tray coupled to a movement mechanism, and a controller. The resin containment structure is supported by the support plate and includes a lower substructure that is moveably coupled to an upper substructure. The upper substructure defines an upper central opening that is closed by a transparent sheet. The lower substructure defines a lower central opening that is closed by a transparent plate. The actuator is affixed to the support plate and configured to rotate the upper substrate about the hinge between a (1) a raised position in which the transparent plate contacts and supports the transparent sheet and (2) a lowered position in which the transparent plate is out of contact with the transparent sheet.

  • Multi-String Section Mill
    Publication number: 20210324696
    Abstract: A multi-string section milling tool has a longitudinally extending tubular body with mill carriers carrying hardened cutters that pivotally extend from a mill window in the tubular body by upward movement of a drive plunger. A downwardly biased piston mounted to the upper end of a flow tube is slidably inserted through a stationary thimble below the piston. The lower end of the flow tube is attached to a drive plunger which is pivotally attached to drive yoke links pivotally attached the mill carriers. The piston and thimble creates a pressure chamber in the milling tool. Fluid pressure in the pressure chamber moves the piston, flow tube and drive plunger upward to pivotally extend the drive yoke links and mill carriers radially outward through the mill window. Cessation of fluid pressure in the pressure chamber retracts the mill carriers.

  • BUSBARS HAVING STAMPED FUSIBLE LINKS
    Publication number: 20210328309
    Abstract: A battery interconnect may include a desired current capacity, integrated fusible links, and be manufacturable using cost effective techniques. In some embodiments, a battery interconnect includes a busbar and relatively thinner links. A busbar carries larger currents and accordingly its cross-sectional areas are relatively larger to reduce ohmic losses. A link carries a much smaller current, and a fusible link is configured to break the circuit when the current is above a threshold, thus requiring a relatively small cross-sectional area. These sometime disparate length scales are addressed using several techniques such as layering a busbar and a foil sheet and pressing portions of a busbar to form the links. The links can be affixed to a plurality of battery cells to connect the cells in parallel or series.

  • SYSTEM AND METHOD FOR THROTTLING SERVICE REQUESTS HAVING NON-UNIFORM WORKLOADS
    Publication number: 20210329077
    Abstract: A system that provides services to clients may receive and service requests, various ones of which may require different amounts of work. The system may determine whether it is operating in an overloaded or underloaded state based on a current work throughput rate, a target work throughput rate, a maximum request rate, or an actual request rate, and may dynamically adjust the maximum request rate in response. For example, if the maximum request rate is being exceeded, the maximum request rate may be raised or lowered, dependent on the current work throughput rate. If the target or committed work throughput rate is being exceeded, but the maximum request rate is not being exceeded, a lower maximum request rate may be proposed. Adjustments to the maximum request rate may be made using multiple incremental adjustments. Service request tokens may be added to a leaky token bucket at the maximum request rate.

  • DISTRIBUTED DIGITAL SECURITY SYSTEM
    Publication number: 20210329013
    Abstract: A distributed security system can include instances of a compute engine that can execute either locally in security agents on client devices or as cloud instances in a security network. Event data can be processed by elements of the distributed security system according to centrally-defined ontological definitions and/or configurations. Bounding managers of local security agents can control how much event data is sent to the security network. A storage engine in the security network can store event data received from client devices, can route event data to other elements of the security network, including cloud instances of the compute engine. An experimentation engine of the security network can also at least temporarily adjust other elements of the distributed security system during experiments or tests.
