Abstract: A firearm training device can include a firearm frame that has a barrel with a camera disposed at a distal end of the barrel, a grip attached to the barrel, and a trigger in proximity to the grip. The trigger can be configured to toggle an electronic switch. The firearm frame can also include a controller communicatively coupled to the camera and the electronic switch. The controller can be configured to collect an image frame or video segment, via the camera, when the electronic switch is toggled, and generate a composite image or video including the image frame or video segment and a strike indicator overlaid onto the image frame or video segment, whereby the composite image or video demonstrates where a firearm strike would have occurred. In other embodiments, the firearm training device is configured as an attachment for a firearm (e.g., a live firearm or mock firearm).

Abstract: The invention comprises a method adapted to manage access to information elements such as classes, data files, objects and methods within a shared library by each of a plurality of applications operating within a respective context. Library contexts including requested information elements are instantiated as necessary for each access requesting application. Location information pertaining to the instantiated library contexts is added to a corresponding location parameter of the requesting applications.
