Abstract: A system and method for operating a semi-automatic firearm as a single-shot firearm by installing a bolt with a bolt lock safety device, wherein the bolt lock safety device extends beyond the outer face of the bolt when engaged preventing the firearm from automatically reloading. The bolt lock safety device can be disengaged to allow pulling the charging handle back to cause the bolt to move rearward exposing the firearm chamber to reload a cartridge.

Abstract: A method for operating a semi-automatic firearm as a single-shot firearm comprising: installing a bolt in the firearm, wherein the bolt comprises a bolt lock safety device, wherein the bolt lock safety device extends beyond a face of the bolt when engaged preventing the firearm from automatically reloading; when the bolt lock safety device is engaged, pulling a charging handle back to cause the bolt to move rearward exposing the firearm chamber to reload a cartridge, wherein the adjustable bolt lock is simultaneously rotated by the lock pivot pin to lay flush with the bolt forcing the bolt back into forward position; and upon release of the charging handle, automatically reengaging the adjustable bolt lock via a lock return spring causing the adjustable bolt lock to extend beyond the face of the bolt.

Abstract: The development of air-stable unipolar n-type semiconductors with good solubility in organic solvents at room temperature remains a critical issue in the field of organic electronics. Moreover, most of the existing semiconducting materials exhibit LUMO energy levels higher than ?4.0 eV, making electron transport sensitive to both moisture and oxygen. Bis(2-oxoindolin-3-ylidene)benzodifurandione dicyanide or derivatives thereof are disclosed herein. More specifically, bis(2-oxoindolin-3-ylidene)benzodifurandione dicyanide or derivatives thereof for use in organic electronics are disclosed. A process for the preparation of bis(2-oxoindolin-3-ylidene)benzodifurandione dicyanide and derivatives is also disclosed. The bis(2-oxoindolin-3-ylidene)benzodifurandione dicyanide or derivatives thereof are characterized by high electron mobilities and are suitable for use as n-type semiconductors in organic electronics.

Abstract: A moving property of a target is measured as the target travels toward a target space. The target including a component that emits light when converted to a plasma. A diagnostic probe system is interacted with a current target moving toward the target space. The interaction occurs prior to the current target entering the target space and after an immediately preceding target has interacted with a prior radiation pulse in the target space. First and second light that is produced at least in part from the interaction between the diagnostic probe system and the current target is detected prior to the current target entering the target space and after an immediately preceding target has interacted with the prior radiation pulse in the target space. One or more moving properties of the current target are determined based on an analysis of the detected first and second light.

Abstract: A method is described for measuring a moving property of a current target as it travels along a trajectory toward a target space. The method includes: detecting a plurality of two-dimensional representations of light that are produced due to an interaction between the current target and each of a plurality of diagnostic probes prior to the current target entering the target space; determining one or more moving properties of the current target based on an analysis of the detected plurality of two-dimensional representations of light, the determining being completed prior to the current target entering the target space; and, if the determined one or more moving properties of the current target are outside an acceptable range, adjusting one or more characteristics of a radiation pulse directed to the target space.
