Abstract: A lens driving apparatus includes a holder, a cover, a carrier, a first magnet, a coil, a spring, two second magnets and a hall sensor. The holder includes an opening hole. The cover is made of metal material and coupled to the holder. The carrier is movably disposed in the cover, and for coupling to a lens. The first magnet is connected to an inner side of the cover. The coil is wound around an outer side of the carrier, and adjacent to the first magnet. The spring is coupled to the carrier. The second magnets are disposed on one end of the carrier which is toward the holder. The hall sensor is for detecting a magnetic field of any one of the second magnets, wherein the magnetic field is varied according to a relative displacement between the hall sensor and the second magnet which is detected.

Abstract: A layout pattern of a magnetoresistive random access memory (MRAM) includes a substrate having a first cell region, a second cell region, a third cell region, and a fourth cell region and a diffusion region on the substrate extending through the first cell region, the second cell region, the third cell region, and the fourth cell region. Preferably, the diffusion region includes a H-shape according to a top view.

Abstract: The present disclosure relates to a system for implementing an immersive Cave Automatic Virtual Environment (CAVE), wherein the proposed system includes a master server engine that is configured to enable multi-side electronic visual displays, and further includes a real-time motion tracking engine that is operatively coupled with the master server engine. The motion tracking engine can be configured to, in real-time, determine cyber-physical position data of at least one motion tracked object across X, Y, and Z coordinates using one or more motion track sensors that are operatively coupled to said real-time motion tracking engine, and enable generation of tracking data of said at least one tracked object based on said cyber-physical position data, said tracking data being used to integrate and visualize said at least one tracked object in said CAVE.
