Abstract: Apparatus, systems, methods, and articles of manufacture are disclosed herein that flexibly form variable component geometries in a roll-forming process. An example roll-forming apparatus includes a forming unit to move along a stationary component to form a cross-section in the component, a first roll operatively coupled to the forming unit to engage the component, and a second roll operatively coupled to the forming unit to set a forming angle for movement along the component, the component formed between the first roll and the second roll.

Abstract: An accessory mounting system for securing an accessory to a firearm includes a slot in a first end of a receiving portion of the firearm, a tab protruding from one end of the accessory, the tab structured to mechanically engage with the slot, and a fastener structured to clamp a portion of the accessory to the receiving portion of the firearm in a location apart from the slot.

Abstract: Methods and Apparatus to increase the efficiency of roll-forming and leveling systems are described herein. An example strip material processing apparatus includes a first drive system to drive an exit workroll at an exit of the strip material processing apparatus, and a second drive system to drive an entry workroll at an entry of the strip material processing apparatus, where the strip material is to travel through the strip material processing apparatus from the entry to the exit. The example strip material processing apparatus also includes a controller to provide a first command reference to the first drive system to drive the exit workroll at the first command reference.

Abstract: A digital turret having an adjustment selector configured to adjust a main optical axis of a riflescope relative to a bore line of a shooting device. The digital turret may be configured to determine a position of the adjustment selector relative to a zero point of the adjustment selector. The digital turret may be further configured to transmit an electronic signal corresponding to the position of the adjustment selector.

Abstract: Methods and apparatus to monitor conditioning machines are disclosed herein. An example system includes a plurality of work rolls to process a continuous strip material positioned between an entry and an exit of an apparatus. A sensor determines a measured distance between an upper surface of the strip material and a reference location, where the sensor is downstream from the exit of the apparatus. A controller determines a difference value between the measured distance and a predetermined distance to detect material curvature in the strip material.

Abstract: Methods and apparatus to monitor conditioning machines are disclosed herein. An example system includes a plurality of work rolls to process a continuous strip of material positioned between an entry and an exit of an apparatus. A sensor is positioned downstream from the exit of the apparatus. The sensor measures a first distance between an upper surface of the strip material and a predetermined reference. The sensor measures a second distance between the upper surface of the strip material and the predetermined reference. The first and second distances is measured at at least one of two different locations or two different instances in time as the strip material exits the apparatus. A controller compares the first distance and the second distance to detect material curvature or longbow in the strip material.

Abstract: Methods and apparatus for controlling flare in roll-forming processes are disclosed. An example method involves predefining a plurality of position values to adjust a tilt angle of a flange roller and adjusting the tilt angle of the flange roller based on one of the pre-defined position values to change an amount of flare in a zone of a component. The one of the pre-defined position values is associated with the zone of the component.

Abstract: A power electronic building block includes a housing; a power module mounted within the housing; a controller mounted within the housing and coupled to the power module; a capacitor assembly coupled to the power module and mounted within the housing; an AC bus bar mounted within the housing; and a DC bus bar coupling the capacitor assembly to the power module and mounted within the housing.

Abstract: The present invention is a segmented LED lighting system. In particular, the present invention is directed to a set of channel segments connected by a flexible lens sleeve that can be positioned in a variety of ways. A printed circuit board with at least one LED is mounted in each channel segment. Each segment preferably has a base with two ribbed vertical sides. The lens sleeve is preferably coextruded from flexible acrylic and has opaque side grips that grip the ribbed vertical sides and a translucent lens portion with an air gap. Pairs of encapsulated PCB modules are preferably connected in series to allow the system to be cut in the field.
