Abstract:
A dispensing system includes a frame, a support coupled to the frame, a dispensing unit configured to dispense viscous material, and a gantry assembly coupled to the frame. The gantry assembly includes a gantry configured to support the dispensing unit and to move the dispensing unit in x-axis, y-axis and z-axis directions and a tilt and rotate subassembly configured to tilt and rotate the dispensing unit. The dispensing system further includes a controller configured to control dispensing unit and the gantry assembly to perform a dispense operation on the electronic substrate. The controller is configured to simultaneously coordinate the movement of the gantry assembly and the tilt and rotate subassembly to position and orient the nozzle of the dispensing unit a predetermined distance and orientation from the electronic substrate while dispensing material along a three-dimensional path.
Abstract:
An integrated system and method to acquire the health state of a structure identifying the presence of damage, and to self-repair the damage in the considered structure. A sensor network installed in the structure is interrogated by a dedicated hardware for damage detection. In case of damage is detected by the sensor network in the structure, the sensor network is triggered and generates harmonic excitation in the structure. Due to the excitation, the natural frequency of vascular microtubes and/or capsules presented in the structure is reached, promoting their disruption. The vascular microtubes and/or capsules disruption along the damage releases the healing compound, repairing the damaged portion of the structure.

In one embodiment, a substrate processing apparatus comprises a chamber lid assembly including a first heating member, a susceptor positioned proximal to the chamber lid assembly, wherein the susceptor includes a second heating member for heating the substrate, a process chamber accommodating at least the chamber lid assembly and the susceptor and a controller configured to control the first heating member so as to refrain the conduction of heat energy generated by the second heating member from the susceptor to the chamber lid assembly.
Abstract:
Disclosed herein is an inventive low-temperature curable antireflective (AR) coating produced by a single layer sol gel deposition process comprising a low-temperature curing step, whereby temperatures well below 100° C. for under 8 hours result in highly robust AR coatings having excellent transmittance and abrasion resistance. Optical, mechanical and chemical properties may be tuned by adjustment of the formulation of the wet coating solution. In this way, the inventive AR coating is able to provide enhanced mechanical and moisture resistance, as well as superior optical performance that can be optimized to suit a particular environment. The invention advantageously enables applying AR coatings to substrates installed in the field, allowing passive heating of the substrate by sun exposure to provide the heat for curing the inventive coatings outdoors.
Abstract:
Methods and apparatus for coating optical articles, such as optical lenses, are provided. In one aspect, an optical article is placed in a holder and a sheet of coating material is discharged from a nozzle, such as from a fan coater nozzle, onto the optical article to form a coating on the optical article.

Paint booths for applying paint to an object, as well as methods for degrading coating operations associated with a paint booth, are disclosed. Paint booth may generally include one or more robot rails positioned parallel to the path of the conveyor, and one or more robots positioned on at least one of the rails. Robots may be configured to simultaneously apply a first paint layer to the interior and exterior surfaces of the object. Paint booths may further include one or more additional robots positioned on at least one of the rails and configured to simultaneously apply a second paint layer to the interior and exterior surfaces of the object.
Abstract:
A glue application method and system comprises a continuous paper substrate moving in a downstream direction along a path of travel. Glue is applied to selected portions of the upper surface of the paper substrate. A first direct contact capacitive sensor under the paper substrate upstream of glue application and in direct contact with the under surface of the substrate produces a signal representative of the dielectric constant of the paper substrate. A second direct contact capacitive sensor under the paper substrate downstream of glue application and in direct contact with the under surface of the substrate with glue thereon produces a second signal representative of the dielectric constant of the paper substrate with glue thereon. A control determines differences between the first and second signals thereby indicating that glue has been applied to the paper substrate.
