Abstract: A disclosed energy regulation and release device capable of balancing energy signatures of flash and sound with practical and tactical concerns of length, recoil and modularity. The energy regulation and release device may include a primary device and a secondary device, and each of those may include a series of internal chambers designed and configured to create a reduction in energy release. The device may thereby achieve a reduction of the signature of a transition of energy from a muzzle of a weapon into an unrestricted atmosphere (internal to external), including a positive buffering, reduction or diminishment of flash, heat, and sound.

Abstract: A method and circuit for determining and extinguishing electrical faults includes a power supply, and electrical load, a controller module, and electrical sensors, and when the controller module does not extinguish the electrical fault, another switch blows a fuse.

Abstract: The invention relates to a fuel cell system and associated method of manufacture. The fuel cell system has at least a first surface region and a second surface region, wherein the first surface region is more hydrophilic than the second surface region, wherein the first and second surface regions are arranged in accordance with a parameter distribution of the fuel cell system.

Abstract: An energy capture and control device can include a central chamber oriented along a central axis within an outer shell. The central chamber can have an inlet configured to receive a bullet from a firearm muzzle, and a central chamber outlet along the central axis. The device can also include an off axis chamber oriented within the outer shell in fluid communication with the central chamber and a fluid outlet to allow fluid to escape from the off axis chamber.

Abstract: Apparatus, systems and methods are provided for trimming a hoof of a horse. The apparatus is an adjustable cutting guide that includes a hoof band configured to extend around the hoof. The hoof band includes an identifier for aligning the hoof band with a mark on the hoof indicating a longitudinal axis of a leg of the horse and a cutting edge providing a cutting plane for a cutting tool. The cutting plane is perpendicular to the longitudinal axis of the leg of the horse. The cutting guide also includes a clamping structure for adjustably clamping the hoof band to the hoof at a user selectable, fixed position above a sole of the hoof when the hoof band is aligned with the mark. The systems include the cutting guide, a marking tool and an alignment tool.

Abstract: A firearm flash hider can include a base module having an attachment surface, an exit surface opposite the attachment surface, and a projectile aperture oriented through the base module to allow a projectile to pass therethrough. The flash hider can include a plurality of contoured deflection walls extending longitudinally from the exit surface and further extending radially from a longitudinal boreline axis extending from the attachment surface to the exit surface along the projectile aperture. The contoured deflection walls can block a line of sight to the boreline.

Abstract: A thermal mirage reducing device for firearms is disclosed and described. The thermal mirage reducing device includes a heat control shell oriented along a horizontal longitudinal axis corresponding to a bore line of a firearm. A cross-sectional profile of the heat control shell taken perpendicular to the longitudinal axis is asymmetrical about a vertical plane dividing the heat control shell along the longitudinal axis. The cross-sectional profile has a heat-directing portion protruding on one side of the vertical plane. The heat-directing portion extends to a high point that is vertically higher than any other point in the cross-sectional profile and laterally offset from the vertical plane. The cross-sectional profile does not intersect the line of sight of the firearm.

Abstract: A firearm flash hider can include a base module and at least one vented flash control module. The base module can have a longitudinal boreline which is fluidly coupleable to a muzzle end of a firearm to allow a projectile to pass therethrough. The base module can also have an inlet port which is operable to receive at least a portion of a flash generated by firing the projectile. The vented flash control module can be arranged along the longitudinal boreline distal to the muzzle end. The vented flash control module can also have a flash chamber bounded by at least one wall that at least partially defines a geometry of the flash chamber and extends both radially and longitudinally from the boreline and translates circumferentially as it extends longitudinally. The flash chamber terminates at a circumferential angle of rotation from the inlet port where the circumferential angle of rotation being less than 180 degrees.

Abstract: A firearm discharge gas flow control module is fluidly coupleable to a muzzle end of a firearm to allow a projectile to pass therethrough. The gas flow control module includes an inlet port, operable to receive at least a portion of a discharge gas generated by firing the projectile, and a gas chamber, bounded by at least one wall that at least partially defines a geometry of the gas chamber. The gas chamber extends both radially and longitudinally from the inlet port and translates circumferentially as the gas chamber extends longitudinally. The gas chamber terminates at a circumferential angle of rotation from the inlet port, the circumferential angle of rotation being less than 180 degrees.

Abstract: An interchangeable, modular firearm muzzle mountable system can include a first firearm muzzle mountable device and a second firearm muzzle mountable device. Each device can have an inlet end coupling feature proximate to an inlet end of a central chamber and an outlet end coupling feature proximate to an outlet of the central chamber. The central chamber can be oriented along a central axis within an outer shell and the inlet and the outlet can be configured to allow a projectile from a firearm to pass along the central axis. The inlet end coupling feature of the first device can be removably coupleable with a muzzle end of a firearm and the inlet end coupling feature of the second device can be removably coupleable with the outlet end coupling feature of the first device beyond the muzzle end of the firearm.

Abstract: A particulate capture module for a high energy discharge device includes a particulate capture shell having an inlet and an outlet. The shell inlet can receive a high energy material discharged from the high energy discharge device. The particulate capture module can further include a self-healing particulate capture material arranged within the particulate capture shell to enable the high energy material to pass through the self-healing particulate capture material. The self-healing particulate capture material can capture particulates associated with discharge of the high energy material from the high energy discharge device.
