摘要： A multi-purpose bayonet knife assembly mounts to the distal end of a firearm barrel to augment the firearm as a pike and detaches to operate as a knife, while also providing integrated utilitarian components having minimal moving parts. The assembly comprises a hilt, a cross guard, and a blade. The hilt has an integral flint and a snap-on hook. The hook detachably couples to the firearm barrel, and also serves to open a bottle. A sleeve houses the hilt. The blade is defined by a longitudinally extending edge defined by: a first serrated edge, a second serrated edge, an angled bevel, and a double-sided blade tip oriented about 30° above the longitudinally extending edge of blade. Blade includes metric and imperial scales, time dial, and compass. Blade forms a dowel hole, nut socket holes, and a longitudinally extending groove. The metallic composition of the blade serves as an antenna.

摘要： Disclosed are embodiments of a sundial. Various embodiments of the sundial disclosed herein may be used to determine the time of day based on the position of the sun. The sundial may utilize a curved reflector to reflect the image of the sun onto a dial-face. The curved reflector may be disposed, at least in part, behind the dial-face. A portion of the curved reflector behind the dial-face may be used to reflect an image of the sun onto a back surface of the dial-face. The reflected image of the sun received on the back of the dial-face may, in some embodiments, be visible on the front surface of the dial-face. The dial-face may have a plurality of time markings positioned thereon. The position of the image of the sun on the dial-face may be compared to the plurality of time markings to determine at least an approximation of the time of day.

摘要： An apparatus receives a digital image of a sun trace chart having time gradient lines and a sun trace extent line for a site. A selector defines on a display points along the solar trace extent line to define a solar opportunity region. An adjuster adjusts the digital image based on the magnetic declination of the site. The solar exposure potential is determined based on the proportion of solar trace extent lines within solar opportunity region and potential solar exposure. Site adjustments to increase solar energy potential are facilitated. A method of evaluating a site for solar energy potential is disclosed. A solar exposure device for recording and analyzing a solar trace is disclosed.

摘要： The present invention is a sundial having first and second spaced parallel planar projection surfaces, the first projection surface defining a summer projection surface and the second projection surface defining a winter projection surface. A gnomon extends perpendicularly between the summer and winter projection surfaces. The gnomon is positioned relative to the summer and winter projection surfaces so that with the sundial in an operative alignment with the parallel projection surfaces parallel to the equatorial plane of the earth, on sunny days a shadow is cast by the gnomon on the summer projection surface during those days when the sun rises above the equatorial plane in the northern hemisphere and a shadow is cast by the gnomon on the winter projection surface during those days when the sun does not rise above the equatorial plane in the northern hemisphere.

摘要： A sundial including a strip-shaped body with surfaces substantially in the form of helicoids. The body is made of a rather thin material. At least one of the helicoids is provided with time markings. As a result, the sundial is very simple to manufacture, and it is very easy to set up. Moreover, it is very easy to read the time, even at a relatively long distance.

摘要： A sundial is disclosed comprising specularly reflective convex surfaces that form virtual images of the sun in a separate plane or conical surface in which a numbered dial plate is mounted. The axis of revolution of the curved surfaces is mounted parallel to the axis of rotation of the earth and the time scale is also centered about this axis, but in a separate plane or cone located at a distance below the nearest reflective convex surface equal to the radius of said convex surface.
