Abstract: Aspects of the present invention relate to control system (100) for controlling a transition of a vehicle between a first driving mode and a second driving mode. The control system comprises one or more controllers, configured to: receive (302) a first request signal indicative of an occupant-initiated preparatory request; receive (303) a second request signal indicative of an occupant-initiated transition request; determine (304) a first control signal for controlling output of information to an occupant of the vehicle indicative of the driving environment in dependence on receipt of the first request signal; determine (308) a second control signal for causing transition of the vehicle from the first driving mode to the second driving mode in dependence on receipt of both the first request signal and the second request signal; and output (306, 310) the first or second control signal to a vehicle system.

Abstract: Embodiments relate to polycrystalline diamond compacts and methods of manufacturing such compacts in which an at least partially leached polycrystalline diamond (“PCD”) table is infiltrated with first and second infiltrants. The first infiltrant includes a low viscosity cobalt-based and/or nickel-based alloy infiltrant. The second infiltrant (e.g., copper) is specifically selected to be more easily infiltrated and/or removed (e.g., leached) than a pure cobalt infiltrant. In an embodiment, a method includes forming a PCD table in the presence of a metal-solvent catalyst in a first high-pressure/high-temperature (“HPHT”) process. The PCD table may be at least partially leached to remove at least a portion of the metal-solvent catalyst therefrom. The leached PCD table and a substrate are subjected to a second HPHT process effective to bond the substrate to the leached PCD table while at least partially infiltrating the PCD table with at least the first and second infiltrants.

Abstract: Embodiments of the invention relate to superabrasive compacts including multiple superabrasive cutting portions and methods of repairing a rotary drill bit that employs at least one of such superabrasive compacts.

Abstract: Embodiments of the invention relate to superabrasive compacts including multiple superabrasive cutting portions and methods of fabricating such superabrasive compacts. In an embodiment, a superabrasive compact comprises a cemented carbide substrate including a first interfacial surface and a second interfacial surface longitudinally spaced from the first interfacial surface. A first superabrasive cutting portion may be bonded to the first interfacial surface of the cemented carbide substrate. The first superabrasive cutting portion includes a first working surface. A second superabrasive cutting portion may be bonded to the second interfacial surface of the cemented carbide substrate and spaced from the first superabrasive cutting portion. The second superabrasive cutting portion includes a second working surface that generally opposes the first working surface of the first superabrasive cutting portion.
