A method of shifting an automated transmission in a vehicle comprises tracking vehicle parameters and determining a current gear selection. An upshift threshold can be determined for the current gear selection. Future gradient conditions are determined in a lookahead distance and are processed to determine a first percentage of future conditions that are above a selected gradient threshold. The first percentage of future conditions is compared to a selected first percentage limit to determine that the first percentage of future conditions is within the first percentage limit. The upshift threshold for the current gear selection is adjusted to change the vehicle parameter at which the vehicle transmission shifts from the current gear selection to the adjacent gear.

BOOSTED SYNCHRONIZER PACK WITH REDUCED AXIAL LENGTH
A synchronizer includes a hub with booster ramps, synchronizer cones, synchronizer rings, and a slide sleeve. The slide sleeve has a gear on an inner surface that is engageable with the synchronizer cones and the hub. The slide sleeve includes a slot. An inner lock contains the synchronizer rings, causing the synchronizer rings to move in an axial direction when axial pressure is applied. An insert is positioned within the slot and has pins extending radially inward. When the slide sleeve is shifted in the axial direction, the insert moves axially and a pin rides along one of the boosted ramps causing the synchronizer ring to engage against the synchronizer cone, causing the synchronizer ring and the synchronizer cone to rotate at the same speed, such that the slide sleeve can be positioned over both the gears of the hub and the synchronizer cone.

An enclosure (1) including a top surface (2), a bottom surface (4), a rear surface (10), sidewalls (6,8), and a door (12) configured to open and close. The top surface, the bottom surface, the rear surface, the sidewalls and the door, when closed, define an interior area. The enclosure further includes at least one barrier assembly (20;60;110;160) attached to at least one of the top surface, the bottom surface, the first side surface and the second side surface in the interior area. The at least one barrier assembly includes a barrier member (22;62;112;162) including a substantially planar barrier portion (30;72;122;168) disposed substantially parallel to one of the top surface, the bottom surface or the sidewalls and a spring assembly (26;66;116;166) attached to the barrier member and configured to bias the barrier portion in a direction of the door.
A contact assembly (100) for an electrical component (2) includes: a bus member (102); and a switching assembly (110) structured to move between first and second positions. The switching assembly (110) includes: a stationary contact (114) extending from the bus member (102), a movable contact (112) engaging the stationary contact (114) when the switching assembly (110) is in the first position and disengaging the stationary contact when the switching assembly (110) moves toward the second position, and a switching device (120) coupled to the bus member (102). When the switching assembly (110) is in the first position, the switching device (120) and the stationary contact (114) are electrically connected in parallel with the bus member (102) and the movable contact (112). When the switching assembly (110) moves from the first position toward the second position, the switching device (120) disconnects power after the movable contact (112) disengages the stationary contact in order that electrical disconnection between the bus member (102) and the movable contact (112) occurs within the switching device (120).
A switching rocker arm constructed in accordance to one example of the present disclosure includes an outer arm, an inner arm, a latch, a roller, a first lost motion spring and a second lost motion spring. The outer arm has a first outer side arm, a second outer side arm, an outer arm first end and an outer arm second end. The first outer side arm has a first leg retaining tab. The second outer side arm has a second leg retaining tab. The inner arm is pivotally secured to the outer arm and has a latch bore, a first inner side arm, a second inner side arm, an inner arm first end and an inner arm second end. The inner arm first end has a first finger, a second finer, a first hub and a second hub.

An exhaust gas energy recovery system includes an internal combustion engine, a volumetric fluid expander, and a water injection mechanism. The internal combustion engine includes an air inlet, at least one cylinder, and an exhaust gas outlet for conveying an exhaust gas stream at a first pressure. The volumetric fluid expander generates useful work at an output shaft by expanding the exhaust gas stream to a second pressure lower than the first pressure as the exhaust gas stream moves through the volumetric fluid expander. The water injection mechanism injects water into the system at a location between the air inlet of the engine and the expander to increase the volume of the exhaust received by the expander for increased power output at the expander.
