  • Publication number: 20190221537
    Abstract: A method of interconnecting components of a semiconductor device using wire bonding is presented. The method includes creating a free air ball at a first end of an aluminum wire that has a coating surrounding the aluminum wire, wherein the coating comprises palladium, and wherein the free air ball is substantially free of the coating. The method further includes the step of bonding the free air ball to a bond pad on a semiconductor chip, the bond pad having an aluminum surface layer, wherein the resultant ball bond and the bond pad form a substantially homogenous, aluminum-to-aluminum bond. The method may further include bonding a second, opposing end of the coated-aluminum wire to a bond site separate from the semiconductor chip, the bond site having a palladium surface layer, wherein the second end of the coated-aluminum wire and the bond site form a substantially homogenous, palladium-to-palladium bond.

    Abstract: A shifter assembly having a housing supporting a detent locking wheel with a biasing return spring. A plunger housing subassembly is rotatably supported within the locking wheel and operating in response to an external input to be rotated between each of Park, Reverse, Neutral and Drive gear shift positions. An electric motor is supported by the housing and is linked to a lock lever, an extending portion of the lock lever engaging the locking wheel. A PCB board is integrated into the housing and is communicable with at least one external sensor associated with a driver exit condition. Upon a triggering of the exit condition with the shifter in other than a Park position, the motor being energized to retract the lock lever to permit the return spring to rotate the wheel to the Park position.

  • Publication number: 20180259063
    Abstract: A rotary shifter having a housing with a bezel cover. A knob is rotatably secured to the housing and is selectively rotatable between each of Reverse Neutral and Drive positions. A push button is configured within the rotary knob and, upon depressing, communicates with a sensor and switch within the housing for establishing the Park position. In a related variant, a Sport position lock ring is secured to a stem of the knob in a normally biasing engagement with an underside of the bezel cover to prevent shifting to the Sport position, the knob being vertically depressed in a counter direction to the bias in order to vertically unseat the lock ring and to permit subsequent rotation to the Sport position. A Sport position spring can also be provided supporting an underside of the plunger housing locker forming a portion of the plunger housing subassembly.

  • Publication number: 20180259062
    Abstract: A rotary shifter having a housing with a bezel cover. An auto return to park mechanism is provided and includes a knob supported upon the bezel cover. A rotary disk stopper is secured to the knob and seated within the housing, a spring rotationally biasing the end stopper relative to the housing. A solenoid is supported within the housing and engages the stopper in a first condition limiting the knob to manual rotary shifting between Park, Reverse, Neutral and Drive gear shift positions. A PCB board is integrated into the housing and communicable with at least one external sensor associated with a driver exit condition. Upon a triggering of the exit condition with the shifter in other than a Park position, the solenoid is energized to disengage the end stopper in a second release condition permitting the spring to reset the stopper and knob to the Park position.

  • Patent number: 7832302
    Abstract: A shift-by-wire shifter system includes a spring biased DTP lever engageable with a shifter lever assembly to move the shifter lever assembly to a park position. A DTP lock assembly secures the DTP lever so that the shifter lever assembly is selectively movable along the shift path during normal operation and releases the DTP lever so that the DTP lever moves the shifter lever assembly to the park position upon the loss of system power. A DTP actuator unlocks the shifter lever assembly and the DPT lock assembly upon the loss of system power so that the DTP lever automatically moves the shifter lever assembly to the park position upon the loss of system power. A power storage device is provided to release power to the DPT actuator upon the loss of system power.

  • Patent number: 7467569
    Abstract: A shifter mechanism includes a shift lever movable along a shift path and a detent assembly. The detent assembly includes a detent profile defining a plurality of gear positions, a bore, a detent plunger located at least partially within the bore, a spring member resiliently biasing the detent plunger into engagement with the detent profile, a split bushing located between the detent plunger and the bore, and a spacer located between the spring member and the bushing. The bushing is located between the spacer and an abutment of the detent plunger, and the spring member is located between the spacer and an abutment of the bore. Contact surfaces between the bushing and the abutment and between the bushing and the spacer are each angled so that a force of the spring member automatically expands the bushing to remove any free-play formed between the detent plunger and the bore.

  • Publication number: 20080098849
    Abstract: A shifter mechanism includes a housing, a yoke assembly having a shifter lever and pivotably secured to the housing along a shift path, and a gate cover secured to the housing and forming a slot. The shifter lever extends through the slot to define the shift path. The gate cover is a unitary component formed separate from the housing. The gate cover provides a gate profile and a secondary detent profile. By changing the gate cover alone, a shifter mechanism with different shifter lever travel or a different type of shifter mechanism can be obtained.

  • Publication number: 20080092608
    Abstract: A locking mechanism for a shift lever includes a detent member movable along a path, a stopper member movable between a locking position to block movement of the detent member and an unlocking position to permit movement of the detent member, and a cam member carried by the stopper member and pivotable relative to the stopper member. In one embodiment, a spring member resiliently biases the stopper member toward the locking position. An electromagnetic solenoid permits relative movement between the cam member and the stopper member when unenergized and prevents relative movement between the cam member and the stopper member when energized. The cam member applies a force to the stopper member to move the stopper member toward the unlocking position in response to movement of the detent member along the predetermined path when the electromagnetic solenoid is energized.

  • Patent number: 7354372
    Abstract: An electric actuator for an automatic transmission includes an adapter to transmit rotary motion between the adapter and the automatic transmission. An electric motor has an output shaft operably connected to the adapter by a gear set which includes a ring gear. The gear set reduces speed and increases torque supplied by the output shaft of the electric motor and applied to the adapter. A release mechanism is operably connected to the gear set and includes a lock member movable between a first position wherein the lock member is in engagement with the ring gear to lock the ring gear against rotary motion in both directions and a second position wherein the lock member is out of engagement with the ring gear to permit rotary motion of the ring gear in both directions.

  • Patent number: 7241244
    Abstract: An electric actuator for an automatic transmission includes an adapter to transmit rotary motion between the adapter and the transmission. An electric motor has an output shaft operably connected the adapter by a gear set which includes a ring gear. A release mechanism includes a solenoid which selectively moves a lock member. In a first position, the lock member engages the ring gear to lock the ring gear so that the adapter is rotated by rotary motion of the output shaft and the adapter rotates to a predetermined zone about a desired gear position. In a second position, the lock member is out of engagement with the ring gear to permit rotation of the ring gear so that the adapter is rotated by internal forces of the transmission and the adapter automatically self-aligns to the exact desired gear position when the adapter is within the predetermined zone.
