DEVICE AND METHOD FOR FABRICATING LOCALLY HETEROGENEOUS COMPOSITE MATERIAL BASED ON TIME-FREQUENCY REGULATED SURFACE ACOUSTIC WAVES (SAWS)
A device and method for preparing a locally heterogeneous smart composite material based on time-frequency regulated SAWs are provided. The method includes: mixing functional particles, a photosensitive liquid and a photoinitiator evenly; inputting periodic time-frequency regulated sinusoidal signals defined by a frequency, a duration, an interval time and a time difference to a pair of slanted-finger interdigital transducers, such that the pair of slanted-finger interdigital transducers are excited to produce corresponding standing SAWs; coupling and allowing the standing SAWs to enter a liquid tank to form a local sound field in the photosensitive liquid; forming, by the functional particles in the photosensitive liquid, a stable array distribution under the action of an acoustic radiation force of the local sound field; and turning on an UV light source for curing, thereby completing the preparation.

SELF RISING BOARD MOLDING
A three-dimensional component is produced in a simplified molding operation. Expandable substrates, which are referred to as blanks, are created by compressing thermobonded nonwovens after heating the binder material above its melting temperature, and then cooling the compressed nonwovens so that the binder material hardens and holds the fibers of the nonwoven together in a compressed configuration with stored kinetic energy. Boards can be formed by laminating two or more blanks together and/or by laminating the blanks with other materials, including non-expendable materials. A mold for the component to be manufactured can be partially filled with a number of boards (or blanks) in a stacked, vertically, adjacent or even random orientation. In addition, the boards or blanks may be cut to create desired shapes of parts that can be placed in the mold.
EDGE SEALANT APPLICATION FOR OPTICAL DEVICES
Techniques are described for applying an edge sealant to the edge of a multi-layer optical device. In particular, embodiments provide an apparatus that performs a precision measurement of the perimeter of an eyepiece, applying the edge sealant (e.g., polymer) based on the precision-measured perimeter, and subsequently cures the edge sealant, using ultraviolet (UV) light that is directed at the edge sealant. The curing process may be performed within a short time following the application of the edge sealant, to ensure that any wicking of the edge sealant between the layers of the eyepiece is controlled to be no greater than a particular depth tolerance. In some examples, the edge sealant is applied to the optical device prevent, or at least reduce, the leakage of light from the optical device, and also to ensure and maintain the structure of the multi-layer optical device.
