Abstract: The invention presented generally refers to an optical adapter device which magnetically attaches one or more optical elements or assemblies to a magnetic portion of an electronic device having a camera. In particular, the optical adapter is shaped to align a first opening in housing of the optical adapter with the camera of the electronic device. The novel device and method utilizes the inherently magnetic properties of the electronic device itself, instead of requiring a predetermined magnetic mate to be built into the electronic device.

Abstract: This invention comprises a self-centering mechanism for retaining an object, a clamping device for retaining an electronic device or an electronic device in a case, and means to integrate the devices in an adapter form. The structure of the self-centering mechanism allows for a compact device that is capable of fitting a wide range of differently sized and shaped objects. The clamping device allows for means to retain an electronic device or an electronic device in a case that is capable of fitting a wide range of differently sized and shaped electronic device. The self-centering mechanism and clamping device can also be integrated into the form of an adapter for various applications.

Abstract: An eyewear retainer for glasses, in which braided tubular sleeves with bonded terminal ends hold onto the temple piece of the glasses. The eyewear retainer consists of two braided tubular sleeves, with at least one of the terminal ends of each sleeve ending in a plurality of terminal ends of the braided strings or ribbons. The two braided tubular sleeves may be connected via a continuous braid or used with another intermediary component. The length of the device is selected for comfortable use and may be adjusted during use. In a preferred embodiment, the bonding of the terminal ends is accomplished, via a silicone-based epoxy to provide a flexible and tacky bond, which allows a more secure hold.

Abstract: This invention comprises an adaptor device for connecting an electronic device having a camera to a range of optical devices, including but not limited to binoculars, monoculars, riflescopes, spotting scopes, telescopes, and microscopes. This adaptor device has a plurality of protrusion that provide a self-centering and fitted connection between the electronic and optical device, so that the optical axes are aligned so that the user may take images or video on their electronic device through the optical device. The structure of the adaptor device allows the adaptor to fit a range of differently sized optical device, denoted by the diameter of the eyepiece end of the optical device.

Abstract: This invention comprises a method of visually comparing the chromatic aberration in two or more optical devices. The test reveals differences in the ability of an optical product to minimize chromatic aberration, so that ideally, various colors (corresponding to specific wavelengths) will have a sharp focus at almost the same distance away from the last optical element. The method provides a consistent way to test the chromatic aberration in various optical products that is more visually observable than the process of noting the halo of colors that appears along the edge of a dark object on a light background. The test is especially geared toward comparing binoculars with different optical material composition such as ED glass (Extra-low Dispersion) or FL (Fluorite) glass to those with conventional types of glass.

Abstract: A covering device for an elongated telescopic sight that is mounted on a gun shaft, wherein the elongated telescopic sight has a first end and a second end, the covering device comprising a first pocket having an opening and a coverable end and a second pocket having an opening and a coverable end, wherein the first pocket is coupled to the second pocket by an intermediate member, oriented non-linearly relative to the second pocket, and is facing in at least a substantially opposite direction as the second pocket; wherein the first pocket is coverable upon the first end of the telescopic sight, the intermediate member is wrappable around, underneath or over at least a portion of the gun shaft and the second pocket is coverable upon the second end of the telescopic sight.
