An automatic paper cutting apparatus includes an X-Y cutter, a cutter controller, and a pattern booklet. The pattern booklet includes a plurality of pattern identifiers and a memory device with cutting instructions for each of the identified patterns. The booklet removably mounts to the cutter controller so that an operator can select a pattern from the pattern booklet and have the memory device provide the corresponding set of cutting instructions to the cutter controller. The cutter controller uses the instructions to control the X-Y cutter and cut the desired pattern. A cutting platform of the X-Y cutter has a tacky adhesive that releaseably secures a work piece to the cutting platform during cutting operations. The cutting platform includes surface features that engage a spur gear. The cutter controller selectively rotates the spur gear to drive the cutting platform in the Y direction. The apparatus may use a journaling, embossing, perforating instrument instead of the cutter to make a pattern on the work piece.

A system and method of transferring digital rights from a first device to a second device. A target rights management object is transferred from the first device to the second device. A probabilistic data structure is created that identifies each of a class of rights management objects that are present on the first device. The probabilistic data structure is employed to determine whether the target rights management object is present on the first device. The target rights management object is utilized on the second device in response to a determination through employment of the probabilistic data structure that the target rights management object is not present on the first device. The target rights management object and its state are returned to the first device in response to a determination through employment of the probabilistic data structure that the target rights management object is present on the first device.

The brush applicator has a tapered inner wall and inwardly extended flange inside of a nozzle, which secures a molded or crimped brush assembly. Two edge applicators apply a substantially uniform thin layer of adhesive or glue only on the edge surface of a workpiece. A first edge applicator applies glue through an exit and a second embodiment of the edge applicator has a roller with side flanges and with a reduced portion in-between. A flat surface applicator may have plural vanes and channels inside of two outer walls to distribute adhesive to a wider flat exit. A biscuit applicator applies glue on two side surfaces of elliptical slots that are formed by biscuit cutters. The glue flows through plural vanes or plural transversely positioned openings and passes to form two opposite layers of glue. A dowel applicator applies a thin substantially uniform layer of glue on the wall of a dowel-receiving hole prior to installation of dowel pins. The glue is applied using a cylindrical nozzle body with plural projections and a reduced diameter portion. A wet well prevents applicator from clogging by hardened glue. The wet well fits tightly over the cap and the entire inner space of the wet well is saturated with moisture/solvent from a water/solvent retainer. A viscous-material applicator dispenses a plurality of beads on the floor or on backside of the workpieces. The viscous-material applicator includes a nozzle that has a flat but wide exit at outlet end, wherein the nozzle has plural vanes or flow restraints to diverge the flow of adhesive to a wider outlet end that has a plurality of orifices.

A pocket drilling fixture has a clamp base with a clamping face formed thereon. Opposing the clamp base is a clamp body with an opposing clamping face. Clamp structure interengages the clamp body and the base. The clamp structure includes a clamp actuator positioned adjacent to the base to move the clamp body in a clamping direction. A guide carrier has at least one drill guide disposed therein, and has an axis which intersects a plane defined by the clamping face. The guide carrier is mounted on the base to move in the direction parallel to the plane. The base may have formed thereon a turret having multiple surfaces for height adjustment. The turret may be positioned under the guide carrier to set its height above the base so that height can be preselected, depending on the workpiece thickness.

A micro-electro-mechanical device including a first substrate; a first contact disposed on a first surface of the substrate; a piezoelectric actuator disposed over the first surface of the substrate; a second contact coupled to the actuator and disposed in proximity to the first contact; a gap control mechanism disposed between the substrate and the actuator for limiting movement of the first contact relative to the second contact. In the exemplary embodiment, the gap control mechanism is a gap control stop constructed of dielectric material. In practice, plural stops are used. In the exemplary embodiment, plural thermosonic bonds are used to connect the actuator to the first substrate. A second substrate is disposed over the piezo-electric actuator. The second substrate has wells over the bonds to facilitate application of a bonding tool to the bonds. The gap control mechanism provides consistent height control between a flipped chip and its base substrate without exposing the assembly to high temperatures.

An apparatus and method for driving an electro-luminescent display panel and a method of fabricating the electro-luminescent display panel includes an electro-luminescent display panel having electro-luminescent light-emitting cells provided at crossings of gate lines and data lines. A current generating circuit generates a current corresponding to an externally supplied digital data. A data driver samples the current from the current generating circuit during each horizontal period to generate a data voltage corresponding to the current and applies the generated data voltage to the data lines. A timing controller controls the data driver, applies the digital data to the current generating circuit, and generates a sampling control signal. The sampling control signal controls the data driver. and applies the sampled signal to the data driver.
摘要:
A removal tool for removing a bonded surface mount component from a printed wiring board. The removal tool comprises a printed wiring board holder for securing the printed wiring board. A base plate is provided and first and second end blocks are fastened to the base plate. The holder is slidable between the first and second end blocks. Two transverse guide shafts extend between the first and second end blocks. A main slide block is slidably attached to two transverse guide shafts, and is slidable along the shafts in response to rotation of the threaded rod. A torque application member is coupled to the surface mount component and to the main slide block for applying a downward force to the surface mount component during removal thereof. A threaded rod is rotatably disposed through the second end block and the torque application means that is rotatable to shear the bond between the surface mount component and the printed wiring board. A load cell may be disposed in the second end block for measuring the amount of force exerted by the removal tool on the surface mount component.
