Abstract: An augmented reality (AR) display is provided. The display comprises a light field generator and a birdbath eyepiece. The light field generator generates a light field as an output. The birdbath eyepiece connects to the light field generator for receiving and projecting the light field to human eye. The birdbath eyepiece comprises a beam splitter and a combiner. The combiner has a curved surface. Each beam of the light field is split into two beams by the beam splitter with one of the split beams reflected by the combiner. Three states-of-use of the birdbath eyepiece are provided for the near-eye light field AR display to transmit the light field to the human eye. A low f-number (or focal ratio) and a large eyebox are obtained to effectively expand the field of view and increase the volume of space within which the human eye can receive the light field.

Abstract: A system and a method for parameter optimization with adaptive search space and a user interface using the same are provided. The system includes a data acquisition unit, an adaptive adjustment unit and an optimization search unit. The data acquisition unit obtains a set of executed values of several operating parameters and a target parameter. The adaptive adjustment unit includes a parameter space transformer and a search range definer. The parameter space transformer performs a space transformation on a parameter space of the operating parameters according to the executed values. The search range definer defines a parameter search range in a transformed parameter space based on the sets of the executed values. The optimization search unit takes the parameter search range as a limiting condition and takes optimizing the target parameter as a target to search for a set of recommended values of the operating parameters.

Abstract: A semiconductor structure includes: an etch-stop dielectric layer overlying a substrate and including a first opening therethrough; a silicon oxide plate overlying the etch-stop dielectric layer and including a second opening therethrough; a first conductive structure including a first electrode and extending through the second opening and the first opening; a memory film contacting a top surface of the first conductive structure and including a material that provides at least two resistive states having different electrical resistivity; and a second conductive structure including a second electrode and contacting a top surface of the memory film.

Abstract: A device is provided to generate a three-dimensional (3D) real image. A display panel is divided into several sub-areas for emitting scenes. Through a projecting lens-array unit, the scenes enter a fusion lens unit to form a real image of light field at a position beyond common barrier. Through an eyepiece unit, the image is emitted to human eye. Thus, the present invention provides a device for near-eye viewing, which reduces existing human-eye vergence accommodation conflict (VAC) in most augmented reality and mixed reality devices. Therein, the display of near-eye light field is a process of light-field reproduction, which merges the scenes and reduces aberration.

Abstract: An innovated SMART Parking System, PRIN System and an Information System are provided. The PRIN System is able to manage multiple parking lots without range limitation, and deeply monitor the individual parking space status and also driveway status at each parking lot upon the control devices deployed. By the bi-directional communication, the control devices are able to be managed and changed the control methodology for dynamic parking service support. Besides, the Information System can provide the real-time parking service information for either remote or local access to assist the quick parking without spending too much driving and searching time for parking. Therefore, the PRIN System and Information System facilitates the problem solving of traffic jam and difficult parking within the city effectively, and significantly reduce the social cost, vehicle emission and carbon monoxide to improve the air we breathe and city environment we care.
