Abstract: A follower for use in a variety of firearm magazines includes a follower body formed of a rigid material and having a bullet engaging surface that is contoured to position the bullets in the magazine so that they are efficiently stacked upon loading. The follower body further includes a rear leg that extends downward from a main generally horizontal surface and a slide lock shelf on one side. A flat follower spring is attached to a bottom of the follower body at one end and has a generally curved shape when in a relaxed state.

Abstract: A flat spring for firearm magazines has a one-piece unitary body with end half-coils at opposite ends and interior coils in a repeating arrangement between the end half-coils. Each of the interior coils includes an upper half-coil and a lower half-coil, each extending between outer tips on opposite sides of the spring body. Increasing and staggering the half-coil lengths, adjusting the radii of the outer tips and shaped matching the end half-coils and upper and lower half-coils within the magazine housing all contribute to a flat magazine spring that uses all available space within a firearm magazine to effectively reduce the number of coils and material thickness so that the compressed spring height is at its absolute minimum, thereby allowing for maximum space for ammunition.

Abstract: A floor plate assembly for a firearm magazine for use in automatic and semi-automatic weapons includes a floor plate having an open back, and the floor plate being structured and disposed for covering engagement over an open bottom of the firearm magazine, and a lock plate including a main plate portion and a grip insert member on a rear portion of the lock plate. The main plate portion is structured and disposed for sliding insertion through the open back end of the floor plate and between the open bottom of the magazine and the bottom of the floor plate. The grip insert member is structured and disposed to cover the open back end of the floor plate, while also matching the contour of the bottom end of the grip, thereby increasing comfort and control while also improving appearance of the firearm.

Abstract: A floor plate assembly for a firearm magazine for use in automatic and semi-automatic pistols and rifles is designed to occupy a minimal amount of space inside the magazine so that more magazine volume is available for bullets in a minimal magazine size. The magazine floor plate assembly includes a floor plate and a lock plate. The floor plate includes opposing lock plate guides that secure to the base flanges of a magazine housing. The lock plate acts as a spring for snap assembly and is inserted underneath the back edge of the magazine housing over the bottom inside surface of the floor plate, so that the lock plate covers the open magazine back side, while keeping the floor plate tight and without movement.

Abstract: A compact firearm spring arrangement within a firearm magazine utilizes two or more springs connected in a linear arrangement by a connecting cup that allows one spring to compress within the other, thereby resulting in a free length spring system having a reduced height when fully compressed. At least one of the springs is a wire spring coiled in an oblong shape and one of the springs is a flat spring for providing increased force density for operation of the firearm. The reduced height of the spring arrangement when fully compressed, and increased force density from the flat spring(s), allows for additional bullet storage space within a magazine of standard size or, alternatively, a more compact system within a magazine that provides an equal amount of bullet storage space while reducing the friction of operation of the firearm.

Abstract: A firearm magazine follower for use in combination with a magazine tube includes an upper flange, a rear flange and a bottom flange formed from a single, flexible piece of material, such as steel. The upper flange extends from the rear flange and has a top side that is sized and configured for supporting a plurality of bullets thereon. The lower flange extends from the rear flange and has a distal end and a proximal end, and includes first and second surface members are separated lengthwise at a location between the proximal and distal ends of the lower flange. The first surface member is sized and configured for contacting a front inner facing wall of the magazine tube. The second surface member includes a raised flange at the distal end that is sized and configured for contacting and activating the slide lock lever of the magazine tube.

Abstract: An basketball arcade game is disclosed that includes a rim, a backboard, a ball sensor for the detection of balls that pass through the rim, a scoreboard for displaying a score relating to the game, a ball control access panel to permit and restrict access to balls that are used with said game, and a central processor that receives input from the ball sensor and provides output to the scoreboard, and the rim further includes a light source and a motor to laterally drive the rim which are both controlled by the central processing unit, and the rim may display light signals reflecting conditions of the game including bonus conditions and the time of play remaining.

Abstract: A compact firearm spring arrangement within a firearm magazine utilizes two or more springs connected in a linear arrangement by a connecting cup that allows one spring to compress within the other, thereby resulting in a free length spring system having a reduced height when fully compressed while maintaining sufficient force for operation of the firearm. The reduced height of the spring when fully compressed allows for additional bullet storage space within a magazine of standard size or, alternatively, a more compact system within a magazine that provides an equal amount of bullet storage space while reducing the friction of operation of the firearm.

Abstract: An amusement game is disclosed that includes a skilled based feature that allows players to try to time the activation of a pressure sensitive switch at the same time a light is illuminated at a target position, and if the player accurately times the activation of the switch, a central proceeding unit sends a signal to a stepper motor to energized and completely open a door that is mounted in a horizontal plane by pivoting downwardly. The door is designed to supports a prize that will be distributed to a player. If the timing is not precise, a signal is sent to a central proceeding unit to incrementally open the door. As the door continues to be opened, any prize that is supported by the door will eventually distributed as the door is allowed to be directed to the prize to a receiving area. Sensors provided on the door detect the absence of a prize on the door and send a signal to a central processing unit to activate a claw mechanism that transfers prizes from a retaining area to a position on said door.

Abstract: A method and device are provided for assigning a task to a user to verify information from a scanned document. An image, a data item, and a data field are presented to a user. The image is associated with at least a section of a scanned document. The data item is identified from a portion of the image. The data field is associated with the data item. A second data item is received. The second data item is entered by the user in the data field and indicates a correction to the data item to reflect the portion of the image. An error rate is updated based on the received second data item. The user is selected to process a task based on the updated error rate. The task is presented to the selected user.
