A surgical instrument comprises a handle assembly including an actuator mounted for manipulation through an actuation stroke. An elongate shaft extends distally from the handle assembly and defines a longitudinal axis. A reciprocating member extends at least partially through the elongate shaft, and is mounted for longitudinal motion through the elongate shaft in response to manipulation of the actuator through the actuation stroke. A drive mechanism includes a first rotating component coupled to the actuator about a first circumference to induce rotational motion in the first rotating component. A second rotating component is coupled to the first rotating component such that rotational motion in the first rotating component induces rotational motion in the second rotating component. The second rotating component is coupled to the reciprocating member about a second circumference such that rotational motion of the second rotating component induces longitudinal motion in the reciprocating member. The second circumference is greater than the first circumference.

The powertrain also includes a secondary shift section realized through a third single pinion planetary gearset, in which a third sun gear is connected to a third planet carrier via a fourth clutch, and is also connected to the housing through a third brake and a second one-way clutch.

A reflective optical encoder for a gear train. The reflective optical encoder includes a gear train with a plurality of gears. Each of the gears is operably coupled to at least one other gear of the plurality of gears. A reflective code pattern is accessible on a surface of at least one of the gears. A reflective optical sensor detects light reflected by the reflective code pattern. Position logic coupled to the optical sensor determines a rotational parameter of the gear train based on the light reflected by the reflective code pattern. Additionally, the position logic may determine rotational parameter of a pinion coupled to the gear train based on the rotational parameter of the gear train.

Also provided are first, second, third and fourth shaft elements, first and second first clutch elements, first, second, and third brake elements, the first clutch element is capable of selectively interconnecting the input shaft and the fourth shaft element. The second clutch element is capable of selectively interconnecting the input shaft and the carrier of the single planetary gear. The first brake element is capable of selectively fixing the first shaft element. The second brake element is capable of selectively fixing the second shaft element. The third brake element is capable of selectively fixing either the sun gear or the carrier of the double pinion planetary gear.

An engine start system which may be employed in automotive idle stop systems. The engine start system includes a pinion gear to be pushed to a ring gear coupled to an engine for achieving meshing engagement with the ring gear. After the pinion gear engages the ring gear, the engine start system starts to rotate the pinion gear using a starter motor to crank the engine. Specifically, when an engine restart request is made following an engine stop request, the engine start system waits until after the speed of the engine drops below a preselected gear engageble speed and then moves the pinion gear toward the ring gear without rotating the pinion gear. This minimizes the consumption of fuel in the vehicle in supplying electric power to the starter motor and a maximum level of mechanical noise arising from the engagement of the pinion gear with the ring gear.

A bi-directional overrunning clutch is disclosed for controlling torque transmission between a secondary drive shaft and secondary driven shafts. The overrunning clutch includes a pinion input shaft in a differential housing that engages with a clutch housing rotatably disposed within the differential housing. At least one race is located adjacent to the clutch housing and is engaged with an output shaft. A cage is located between the race and the clutch housing. The cage is movable with respect to the clutch housing. A <DEL-S DATE="20030304" ID="DEL-S-00001" / >first<DEL-E ID="DEL-S-00001" / > coil is mounted within the differential housing adjacent to the cage and is adapted to produce an electromagnetic field when energized which causes the cage to drag with respect to the clutch housing.

The second coil is adapted to produce an electromagnetic field when energized which advances cage with respect to the clutch housing causing the clutch housing to engage with the races. When the second coil is activated, the output shaft drives the pinion input shaft producing engine braking. An electronic control system is utilized to control the energizing of the coils.

A mechanism for extending and supporting a high-lift device relative to an airfoil has a pair of support ribs coupled to the airfoil. A carrier track is pivotally coupled to the high-lift device and positioned between the pair of support ribs. The carrier track has a slot opening along a lower length thereof. A gear rack is coupled within the slot opening. A pinion gear is positioned between the support ribs and below the carrier track. The pinion gear engages with the gear rack for extending the high-lift device relative to the airfoil. A plurality of rollers is rotateably coupled to the support ribs and in bearing contact with the carrier track. At least one roller is positioned above the carrier track and a second roller is positioned below the carrier track. The second roller is positioned concentrically with the pinion gear.

A pressure cooker includes a bowl and a removable lid carrying at least two jaws mounted to move on the lid between a locking position for locking the lid on the bowl and an unlocking position, each jaw being connected to a slider mounted to slide on the lid so that sliding of the slider causes the associated jaw to move towards one of the positions. A pinion is mounted to turn on the lid about an axis that is vertical in operation, each slider having a rack-forming toothed portion which co-operates with the pinion so that turning the pinion causes all of the jaws to move simultaneously towards one of the positions.
