Patents by Inventor Tobias Gerfin

Tobias Gerfin 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).

  • Patent number: 7800034
    Abstract: A dazzle protection unit (1) for a portable dazzle protection device that includes an optical dazzle protection filter (3) and at least one sensor (5) for the sensing of incident light and for controlling the translucency of the filter (3). In doing so, the dazzle protection unit (1) includes a light capturing element (4), which captures incident light on a light capturing surface area (12) and conducts it to the at least one sensor (5). The light capturing element (4) preferably captures the light from several areas located at a distance from one another on a front side of the dazzle protection unit (1). Means (8) for coupling light into the light capturing element (4) are situated at a distance from one another.
    Type: Grant

  • Patent number: 7008055
    Abstract: An eye protection apparatus includes a selectively darkenable element, such as a liquid crystal panel, and a controller that causes transmission of a darken signal that causes the selectively darkenable element to darken in conjunction with an emission of light, such as intense diffuse light that is used in some medical procedures. Protection against both laser light and diffuse light may be provided in the same eye protection apparatus. The darken signal may be transmitted prior to the emission of the diffuse light, and cause the selectively darkenable element to achieve a darkened state prior to emission of the diffuse light.
