Abstract: A method for shifting a segmented gear may include rotating a gear cluster including a first gear and a coaxial second gear using a power transfer mechanism (e.g., a belt or a chain). The power transfer mechanism defines a plane and is wrapped partially around the first gear. and wherein the first gear has a plurality of gear segments independently movable (e.g., pivotable or translatable) into and out of the plane. A plurality of radially transitionable sliders are rotated in tandem with the first gear, and each of the sliders is operatively coupled to a corresponding one of the gear segments of the first gear. In sequence, each segment of the first gear is moved out of the plane of the power transfer mechanism by urging the slider in a radial direction using a segment actuator, such that the power transfer mechanism wraps at least partially around the second gear.

Abstract: Vehicles and related systems and methods are provided for controlling a vehicle in an autonomous operating mode. One method involves obtaining navigation information for a route for the vehicle from a navigation system, transforming the navigation information into data points defining an upcoming trajectory of the route, mapping the data points to a corresponding mapped set of lane segments encompassing one or more of the data points, assigning lane preference indicia to the mapped set of lane segments, and autonomously operating one or more actuators onboard the vehicle to laterally maneuver the vehicle into one or more lanes at respective longitudinal positions along the route corresponding to one or more lane segments of the mapped set of lane segments in a manner that is influenced by the lane preference indicia assigned to the lane segments.

Abstract: A Ported Press Adapter Expand Mandrel System (PPAEMS) includes a Ported Press Adapter (PPA) as a significant advancement beyond the Expand Mandrel Window Riser (EMWR) by adding multiple radial holes to provide increased light intrusion, full 360° visibility, and balanced stress distribution with a pattern of port holes, slots, or other openings.

Utilizing a small diameter Mandrel Holder (MH) allows for a wide range of mandrel diameters for installation in tight working areas (coax and progressive presses) and improves axially precision with a fine thread pitch.

Abstract: One or more systems for automated preparation of a regenerative epidermal suspension comprises a base unit, a cartridge assembly containing a cup, and a tissue disaggregator. The system may also include related tools. The system executes one or more sequences wherein a first motor actuates the pestle against a tissue sample that is disposed along a screen within the cup while the tissue sample is in contact with, in sequence, an enzyme solution, a first buffer solution, and then a second buffer solution. To transition between fluidic contact stages or steps, the tissue disaggregator engages with and lifts the cup into a raised position within a processing area of the cartridge while a base plate motor rotates the appropriate well into alignment under the cup for each processing step. Once the sequence is complete, a user may draw up a regenerative epidermal suspension through an opening in the cartridge top cover.

Abstract: A secure connection is established between an IAM server on a data communication network and an on-premises active directory using a zero trust tunnel based on TCP forwarding. An authentication request is received from a gateway device, for the user to access a service provider hosting applications, responsive to a user request for access to the service provider hosting applications. Responsive to recognizing the user of the authentication request being associated with the established SSO session, an assertion is returned to the gateway that the user is authenticated to access the service provider. An authentication request is received from the service provider, for access to a specific application. Responsive to the group information associated with the user, an assertion is returned to the service provider that user is authenticated for use of the specific application.

Abstract: A network appliance is configured to provide inline traffic inspection for all flow through the device, to selectively intercept based on traffic content or policy, and to modify intercepted traffic content, all without connection termination and re-origination. Content modification may involve substitution of traffic content with smaller or larger content, in which case the device provides appropriate sequence number translations for acknowledgements to the endpoints. This streaming rewrite may occur on a byte-at-a-time basis, while keeping the session alive and without a need to proxy it. The appliance enables transmitted TCP data to be modified inline and then reliably delivered without the overhead of forwarding packets through a full-blown TCP stack. Rather, the approach relies upon an initiator entity's TCP stack for congestion control, as well as the receiving entity's re-transmission behavior to determine how the device manages packets internally.

Abstract: Described herein are examples of differential pressure sensors designed to work with dynamic, high pressure, hydraulic systems. The sensors have a one piece sensor housing that is durable enough to withstand intense fluid pressures and associated stresses. Additionally, the sensors use foil (rather than, for example, piezoelectric) strain gauges to enable pressure measurement even under the unique stresses imposed by dynamic, high pressure, hydraulic systems. Furthermore, the sensor tubes of the sensor help to isolate the strain gauges from some of the bowing/bending stresses that the main body of the sensor may experience due to the intense fluid pressures.

Abstract: Techniques for performing fine-scale movement tracking of underwater objects are described. A computing device or system may receive timestamps corresponding to acoustic signals detected using an underwater acoustic receiver. The device or system may select a period of a known acoustic transmitter, and generate raw image data plotting the timestamps as graphical elements with respect to a first axis corresponding to linear time, and a second axis having a magnitude corresponding to the selected period. A first machine learning (ML) model may process the raw image data to generate segmented image data include a subset of the graphical elements determined to correspond to the selected period. A portion of the segmented image data, including the graphical elements, may be input to a second ML model to generate image data comprising a subset of the graphical elements corresponding to the selected period.
