  • Patent number: 8435804
    Abstract: A method for producing a lamina from a donor body includes implanting the donor body with an ion dosage and separably contacting the donor body with a susceptor assembly, where the donor body and the susceptor assembly are in direct contact. A lamina is exfoliated from the donor body, and a deforming force is applied to the lamina or to the donor body to separate the lamina from the donor body.
    Type: Grant

  • Patent number: 8268645
    Abstract: A method for producing a lamina from a donor body includes implanting the donor body with an ion dosage and heating the donor body to an implant temperature during implanting. The donor body is separably contacted with a susceptor assembly, where the donor body and the susceptor assembly are in direct contact. A lamina is exfoliated from the donor body by applying a thermal profile to the donor body. Implantation and exfoliation conditions may be adjusted in order to maximize the defect-free area of the lamina.

  • Patent number: 8226142
    Abstract: A workpiece gripping integrity device and method are provided having a charge-transfer sensing device configured to detect a change in charge associated with a gripper arm assembly based on a grip condition thereof. The charge-transfer sensing device can be configured to detect a change in capacitance between the gripper arm assembly and ground, wherein the change in capacitance is based on a grip condition of the gripper arm assembly associated with a plurality of grippers contacting the workpiece.

  • Patent number: 5014841
    Abstract: A clutch adjustment and lockup system is disclosed. The system is adapted for use with a centrifugally actuated friction clutch of the type wherein clutch plates and clutch disks are engageable with each other. The conventional friction clutch includes a weight support member having apertures concentric with the plates and disks and is interlocked with the plate for rotation therewith. The conventional support member includes a plurality of pivotable weights causing the plate to frictionally engage the disk upon rotation of the support member. Springs are provided to counteract the weights, thereby resisting frictional engagement of the plates and disks until a predetermined speed is achieved. The improved adjusting system allows remote setting of the speed at which the plates frictionally engage the disk while the vehicle is moving and a lockup system provides increased frictional engagement of the clutch plate and disks.
