Abstract: Systems and methods for generating patient-specific surgical guides comprising: capturing a first and second images of an orthopedic element in different reference frames using a radiographic imaging technique, detecting spatial data defining anatomical landmarks on or in the orthopedic element using a neural network, applying a mask to the orthopedic element defined by an anatomical landmark, projecting the spatial data from the first image and the second image to define volume data, applying the neural network to the volume data to generate a reconstructed three-dimensional (“3D”) model of the orthopedic element; and calculating dimensions for a patient-specific surgical guide configured to abut the orthopedic element.

Abstract: An improved rifle includes a magazine body attached to the rifle, and a base plate releasably and slidingly engaging the magazine body and forming a base of the magazine body. A release is provided to unlock the base plate when actuated by a user of the rifle. The base plate is configured to move away from the magazine body when unlocked, thereby exposing an inner chamber of the magazine body for insertion of an ammunition stripper clip thereinto.

Abstract: An automated cat litter disposal system for a cat litter box having a floor, upstanding side walls and end walls. A set of parallel tracks extend along the side walls. The tracks include lower sections extending from one end wall, upright sections rising from the lower sections proximate to the other end wall, and upper sections extending between the upright sections and the second end wall. A rigid scoop extends across the width of the cat litter box and is mounted by track followers to move along the track. The scoop has a lever mechanism which bears against the scoop guide that follows the course of the tracks. An electric motor drives the scoop along the tracks with the scoop lever bearing against the scoop guide.
