Abstract: A virtual and real information integration spatial positioning system includes an image output device, a processor unit, at least one network gateway, a plurality of mesh routers, a millimeter wave vibration detection module, a sound detection module, a wireless positioning module, and an image capturing module. The millimeter wave vibration detection module or the sound detection module or the wireless positioning module or the image capturing module is operable to acquire a signal feature value of a state of an article or an environment, which is transmitted through the mesh routers and the network gateway to the processor unit to generate positioning information of the article or the environment to be displayed on the image output device, to generate a simulation image that simulates the state of the article or the environment according to the signal feature value and a real image thereof.

Abstract: An integrated endoscope and visualization system comprises an endoscope, a visualization processing module and a 3D display device such as smart-glasses or naked-eye 3D display. The endoscope is equipped with two image capturing modules such as CMOS image sensors and can be disposable. The visualization processing module receives and encodes the images obtained by the two image capturing modules in order to generate an output visualization signal. The output visualization signal is transmitted to and displayed by the 3D display device in a 3D manner. The integrated endoscope and visualization system not only provides a 3D vision of surgical target during an endoscopic surgery operation, but also allow the medical personnel to walk or move during the surgery while keeping looking at the 3D images captured by the endoscope through wearable display devices.

Abstract: The display adaptor device connects between an intelligent wearable device and a smart phone. The device includes a casing with a holder socket provided on the casing; a first transmission member including two Universal Serial Bus (USB) ports, one provided inside the holder socket and the other one on an outside surface of the casing; an adaption member including a video processor, an audio codec, a sensor signal processor; and a second transmission member including an input/out (I/O) port on the casing. The first transmission member is electrically connected to the video processor, the audio codec, and the sensor signal processor, which in turn are electrically connected to the second transmission member. A smart phone is plugged in the holder socket. A cable connects the I/O port and an intelligent wearable device. The display adaptor device provides two-way video communications between the wearable device and the smart phone.

Abstract: The see-through eyepiece includes a first prism, a second prism, and a partially reflective layer. The first prism has an input surface, a flat first total internal reflection surface, and a first interface surface. The second prism has a second interface surface, a flat second total internal reflection surface, and a reflection surface. The partially reflective layer is disposed between the second interface surface and the first interface surface. The second and first prisms are attached together along the second and first interface surfaces, thereby forming the complete see-through eyepiece. The present invention is able to reduce the traversal distance of light within the prisms, effectively lowering the thickness of the see-through eyepiece, or enhancing its field or angle of view. A user may perceive images more easily and conveniently, achieving better product performance and applicability.
