This technology is particularly useful in digital educational tools and multilingual documentation, facilitating easier reading and comprehension.

Abstract: A differential includes a disconnect feature. When in a disengaged state, the drive gear is decoupled from the differential carrier. As a result, the portions of the powertrain that would provide propulsion through the differential may be stationary and parasitic drag is decreased. The differential is transitioned into an engaged state by providing electrical current in a solenoid coil fixed to the housing. A solenoid piston acts through a thrust bearing to slide a sleeve, thereby coupling the carrier to the drive gear.

Abstract: Systems, methods, and computer program products for alarm response automation in manufacturing, distribution, and general supply chain environments. Sensors categorized as part of an industrial IoT environment are used to detect asset health, including asset abnormalities and trends. Alarm exceptions generate actionable events, which are used to invoke a multi-tiered, hierarchical application of asset entitlements. This data guidance provides enhanced alarm response automation via intelligent filtration and consolidation by grouping recurrent or related alarms from assets, models, model types, components, customers, and sites into a single actionable event. This actionable event has its own unique categorizations that work in concert. At any point, additional, definable processes may be executed to further refine the data. The resulting layered, asset entitlement approach thereby creates a high level of filtration and intelligence from the IoT-generated data.

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: A controlled fusion reactor that is constructed using two opposing bowl-shaped magnetic arrays that are covered by U.S. Pat. No. 8,638,186 B1 by the same inventor. The opposing bowl-shaped magnetic arrays are contained within a chamber under a high vacuum level and can be fed a controlled amount of a gas, such as hydrogen. Electrodes located in the bottom of the bowl-shaped arrays and the conductive screens surrounding the rim of the bowl-shaped magnetic arrays are supplied with high-voltage electricity which causes a high-velocity jet of plasma to be ejected from each opposing bowl-shaped magnetic array. The construction of the fusion reactor is such that the plasma jets collide in the middle of the reactor between the two bowl-shaped magnetic arrays. An additional element, such as boron, is fed to the reactor when the goal is the fusion of elements such as hydrogen and boron.

Abstract: An execution unit circuit for use in a processor core provides efficient use of area and energy by reducing the per-entry storage requirement of a load-store unit issue queue. The execution unit circuit includes a recirculation queue that stores the effective address of the load and store operations and the values to be stored by the store operations. A queue control logic controls the recirculation queue and issue queue so that that after the effective address of a load or store operation has been computed, the effective address of the load operation or the store operation is written to the recirculation queue and the operation is removed from the issue queue, so that address operands and other values that were in the issue queue entry no longer require storage. When a load or store operation is rejected by the cache unit, it is subsequently reissued from the recirculation queue.
