Abstract: Embodiments include method, systems and computer program products for a path-sensitive contextual help system. In some embodiments, user actions are obtained from a user session of a user. A concrete user action trace is captured using the obtained user actions, wherein the concrete user action trace is a subset of user actions from the user session. An abstract user action trace is generated using the concrete user action trace. A help action corresponding to the abstract user action trace is identified and, in some embodiments, is presented to the user.

Abstract: A mud screen manifold in which a saver sub chamber, a screen chamber and a mud inlet chamber are formed in a body. A hollow saver sub is provided, suitable for insertion into the saver sub chamber after connection to a screen cage. When a shaped flange on the saver sub is received into a correspondingly shaped recess formed in the saver sub chamber, a mud flow inlet is in fluid flow communication with a cutout in the saver sub via the mud inlet chamber, and the saver sub is in fluid flow communication with the screen chamber via fluid flow through the screen cage. Contact seals prevent fluid flow from leaking around the screen cage. The mud inlet chamber, the saver sub and the saver sub cutout preferably cooperate to form a smooth-walled passageway for fluid flow communication between the mud inlet chamber and the screen cage.

Abstract: Synergistic induction and turbocharging includes the use of one or more throttles in close proximity to each cylinder intake valve to control air flow in each intake port delivering air to combustion cylinders in an internal combustion engine system. A turbocharger may also be affixed in close proximity to each cylinder exhaust valve to enable a synergistic combination of hyper-filling cylinders with combustion air and immediate harvesting of exhaust gas by adjacent turbochargers. In some implementations the turbochargers may be low-inertia turbochargers. The combination of individual throttles per intake port and a turbocharger in close proximity to each cylinder enables faster ramp-up of an engine in the early stages of acceleration. Various implementations thus provide improved fuel economy and improved engine performance in tandem, instead of one at the expense of the other.

Abstract: Cross-port air flow that improves engine fuel economy and reduces pumping losses during part-throttle operation can be implemented in various types of internal combustion engine systems using ports that interconnect the intake ports of different cylinders, thus allowing different cylinders to share combustion air. Cross-port air flow is commenced during part-throttle engine operation to disrupt the primary combustion air flow from each throttle to its associated cylinder, which reduces charge density and engine power. The engine compensates for the reduced power by incrementally opening the throttles, thus increasing the primary combustion air flow, reducing pumping losses and improving fuel economy.

Abstract: Synergistic induction and turbocharging includes the use of one or more throttles in close proximity to each cylinder intake valve to control air flow in each intake port delivering air to combustion cylinders in an internal combustion engine system. A turbocharger may also be affixed in close proximity to each cylinder exhaust valve to enable a synergistic combination of hyper-filling cylinders with combustion air and immediate harvesting of exhaust gas by adjacent turbochargers. In some implementations the turbochargers may be low-inertia turbochargers. The combination of individual throttles per intake port and a turbocharger in close proximity to each cylinder enables faster ramp-up of an engine in the early stages of acceleration. Various implementations thus provide improved fuel economy and improved engine performance in tandem, instead of one at the expense of the other.

The ratio (?Rhalf??Ghalf)/(?R??G) is greater than 0.70.
