Abstract: The disclosure provides an augmented reality (AR) device, a notebook, and smart glasses. The AR device includes a laser source, a spatial light modulator (SLM), and a hologram optical element (HOE). The laser source provides a coherent laser ray. The SLM provides a diffraction pattern solely corresponding to the coherent laser ray. When the SLM receives the coherent laser ray, the diffraction pattern diffracts the coherent laser ray as a hologram in response to the coherent laser ray. The HOE provides a concave mirror effect merely in response to a wavelength of the coherent laser ray, wherein the HOE receives the hologram and magnifies the hologram as a stereoscopic virtual image.

Abstract: An ostomy pouching device for the removal of biological waste from a patient. An embodiment of an ostomy pouching device includes an outer container housing an inner bag for receiving waste from a patient's bowel. The device includes a bowel connector to connect the bowel to the inner bag. The outer container includes an air exit aperture through which air may exit the container as it is displaced as the inner bag expands, and a gas tunnel for removing gas from the inner bag.
