Abstract: A fastening assembly for a top-mounted faucet that allows quick and easy installation of the faucet. The fastening assembly includes a plate and a threaded nut. The plate includes an upper grip member made of soft gripping material and a lower support member made of a rigid material. The plate has an elongated central aperture passing through the upper grip member and lower support member. The lower support member includes two flanges that clamp to opposite two faces of the threaded nut.

Abstract: A compressible tank for supplying water under pressure, such as in water filtration systems. The compressible tank includes a pleated body that can compress and expand upon folding and unfolding of the pleats, respectively. The compressible tank includes a pump, a pressure sensor, and a float valve. The pump can supply the water under pressure. The pressure sensor can operate the pump based on the pressure at the outlet port. The float valve can open and close the inlet valve based on the level of the water in the body.

Abstract: A completely biodegradable cartridge for a water filter that can replace traditional non-biodegradable cartridges. The cartridge may also include one or two caps also made from biodegradable material.

Abstract: A shopping cart system that includes an image that can be applied to the packaging of an item. The image may be invisible in a visible light spectrum but only visible in radiations of a specific spectrum or within a range of wavelengths that are outside the visible light spectrum. An optical scanner unit that can scan the image on the package. The optical scanner unit can include a lamp that can generate the radiations in the specific spectrum in which the image can be scanned. The optical scanner unit can be mounted to a shopping cart such as to track items being placed or removed from the shopping cart.

Abstract: A shooting target that can be reused multiple times and can also capture bullets hitting the target. The shooting target includes a base having a front face. Several spaced and upstanding tines protrude from the front face of the base. The tines are configured to retain the bullets hitting the shooting target.

Abstract: A shooting target assembly that can be reused multiple times. The shooting target assembly includes a base having a front face and a rear face. The front face of the base having one or more layers of pressure-sensitive coating. The pressure-sensitive coating is such as an area of the coating receiving the impact of the bullet hitting the shooting target can change in color, thus showing the point on the shooting target being hit by the bullet.
