Abstract: A device facilitates adjustment of a sight on each of a variety of firearms having different calibers by providing a visible mark on a target when the device is placed within a chamber of any of the firearms. The device includes a housing, and a laser module energizeable within the housing to produce the mark at a position along a laser axis extending through the firearm's barrel. An outer sleeve fits snugly around at least a portion of the housing, and has an external shape sized to fit snugly within a chamber of predetermined caliber for one of the firearms. A power supply situated either within the housing or within the sleeve electrically energizes the laser module.

Abstract: A device facilitates adjustment of a sight of a firearm by providing a visible mark on a target when the device is placed within a chamber of the firearm. The device may include a laser module energizeable within the chamber to produce the mark at a position along a laser axis, a power supply situated within the chamber to energize the laser module when an electrically conductive flowpath is completed with the laser module, and an electrical circuit including a conductive part of the firearm through which electrical current flows to complete the flowpath. A method of laser module alignment is also demonstrated involving rotation of and limited linear motion of the laser module.

Abstract: An intelligent network includes service switching points, where the call switching is made and where data relating to calls and signals indicating various events relating to the calls are generated Service control points are connected to the service switching points. A service control point includes a service control function for processing events relating to calls. The service function includes predefined building blocks or control types, which are executed for specific events relating to a call. In order to provide an interface to the exterior allowing some customer design or customer programming, in particular to servers including some service finction which is supplied by the customer running the server, the servers are connected to the network only at a single service control point. The service control function in this service control point includes therefor a remote procedure building block, which transfers, when it is executed for an event relating to call, data relating to the call to a data buffer.
