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: An intraocular pressure inspection device includes an intraocular pressure detection unit, a high-precision positioning system and a wide-area positioning system, wherein according to the position of the intraocular pressure detection unit, a set of high-precision coordinates output by the high-precision positioning system and a set of wide-area coordinates output by the wide-area positioning system are integrated in appropriate weights to obtain a set of more precise integrated coordinate. The above-mentioned intraocular pressure inspection device can prevent the intraocular pressure detection unit from failing to operate once it is not in the working area of the high-precision positioning system.

Abstract: A door lock includes a main part including an axial tube and a connection tube extending on two ends thereof. A mounting plate has a mounting hole and at least one first engaging portion. A first plate has at least one second engaging portion which faces the mounting plate. Multiple first fixing members extend through the first plate and are not connected to the mounting plate. A second plate is mounted to the connection tube and includes multiple positioning holes. Multiple fastening members extend through the positioning holes and are connected to the first fixing members. The second connection portion is threadedly connected to the first connection portion to adjust a distance between the mounting plate and the main part so that the door lock can be installed to doors of different thicknesses.

Abstract: The present application relates to the field of semiconductor, especially the Light-Emitting Diode (LED) and a manufacturing method thereof. In some examples, by etching the channel between adjacent light-emitting units, making the high reflection layer at the bottom of the channel, and producing interference fringes through the high reflection layer, and the side of the LED is exposed by using the interference fringes, thereby forming the structure of the groove and the protrusion on the side of the LED. Further, the width of the bottom of the groove can be larger than the width of the opening, and a silicon dioxide layer can be provided on the surfaces of the protrusion structures, which can further improve the luminous efficiency of the LED.

Abstract: A deadbolt lock includes a positioning member mounted to a lock part. A protective member includes a recess formed in one side thereof and is mounted to the lock part and the positioning member. A covered area is formed between the positioning member and the protective member. At least one fixing member is connected to the positioning member and located within the covered area. An outer cover is mounted to the protective member and the positioning member. The at least one fixing member is compact in size to reinforce the protective member to reduce manufacturing cost. The protective member and the outer cover are not damaged by impact from outside of the deadbolt lock to enhance safety features of the deadbolt lock.
