Wolfgang Adam Mack, Jr. has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20140060639
    Abstract: The present application relates to a copper oxide nanocrystal with a cupric oxide (CuO) shell surrounding a cuprous oxide (Cu2O) core. The copper oxide core/shell nanocrystals may be used as photo-absorbers in photovoltaic cells. The copper oxide core/shell nanocrystals form a p-type semiconductor layer that coats and fills the interstitial gaps of the n-type semiconductor mesoporous structure in a photovoltaic cell. The n-type semiconductor layer may include, for example, titanium dioxide (TiO2) particles.

  • Patent number: 6369952
    Abstract: A visual display device is provided for delivering a generated image, preferably combinable with environment light, to the eye of a user. The device is lightweight and compact but yields a high quality image. In one embodiment, a shroud protects from stray light and holds optical elements in desired alignment. In one embodiment an image generator is masked by at least two masks to provide for a high quality image without waste. In one embodiment, a removably mounted shield or activatable device and convert the apparatus from a see-through device to an immersion device and back again. In one embodiment, the device can be comfortably mounted to the user's head while still allowing for use of conventional eyeglasses. A tracker for outputting an indication of the orientation, attitude and/or position of a head-mounted display (HMD) may be provided.

  • Patent number: 6160666
    Abstract: A visual display device is provided for delivering a generated image, preferably combinable with environment light, to the eye of a user. The device is lightweight and compact but yields a high quality image. In one embodiment, a color shutter provides a high-density color image. In one embodiment, a shroud protects from stray light and holds optical elements in desired alignment. In one embodiment an image generator is masked by at least two masks to provide for a high quality image without waste. In one embodiment, a removably mounted shield or activatable device can convert the apparatus from a see-through device to an immersion device and back again. In one embodiment, the device can be comfortably mounted to the user's head while still allowing for use of conventional eyeglasses. In one embodiment various controls, such as a mute button, volume control and the like can be provided, such as by mounting on the head-mounted display device.

  • Patent number: 6097543
    Abstract: A visual display device is provided for delivering a generated image, preferably combinable with environment light, to the eye of a user. Light from an image generator such as a CRT, LED or LCD is reflected from a fold mirror away from a user's eye towards a combiner. The image is reflected from the combiner and magnified, optionally combined with light from the environment and passes back through the fold mirror towards the eye of the user. In one embodiment, an optical element such as a meniscus lens or PCX lens is used to present the user with a substantially flat focal field and/or a Fresnel lens or diffractive optical element is used to aim rays from the image to the field curvature corrective lens in order to maintain maximum contrast.
