Abstract: A handgun slide has a slide body extending longitudinally and includes sides extending down from a top surface. A proximal end portion of the slide body defines a recess configured to receive a sight assembly. A sight assembly can be installed in the recess of the slide by placing the sight assembly in the recess, followed by securing the assembly to the slide. In its installed configuration, at least part of the sight assembly's point-of-aim indicator is recessed below the top surface of the slide.

Abstract: A lyrics display apparatus for an automobile including a lower base unit and an upper base unit. A bottom side of the lower base unit is removably disposed on a dashboard of an automobile. A rechargeable battery, a first storage element, and a central processing unit are disposed within the upper base unit. A charging port, at least one battery status indicator light, an activation control, and a display screen are disposed on the upper base unit. A projector, a speaker, and a microphone are disposed on the upper side of the upper base. The central processing unit is configured to recognize and acquire lyrics of a song from the first storage element when the microphone relays the song to the central processing unit. The projector is configured to display lyrics of the song recognized and acquired by the central processing unit onto a windshield of an automobile.

Abstract: A door bolt safety lock has a base unit attached to a top unit via a hinge, and a latching mechanism that engages when the top unit is closed over the bottom unit around a sliding bolt protrusion, preventing the sliding bolt from being moved until a release button is pressed. In operation, the latch engages the top and bottom units, compressing a spring and holding the device in the closed position until the latch release is pressed. In an alternate embodiment, the base unit is shorter than the top unit. The top unit is closed over the bottom unit and the sliding bolt protrusion, trapping the protrusion between the top unit and the door.
