Abstract: A reticle for use in a firearm scope that compensates for the trajectory of a bullet, allowing the shooter to accurately engage the target despite the target's distance from the shooter. The reticle uses a number of trajectory arcs and distance markings that correspond to the target's size and distance to provide the shooter with an accurate aiming of the target. Once the outer edges of the target aligns with the trajectory arcs the target is ready to be engaged. Distance markings, windage markings, and reticle illumination provide for further accuracy of the shot. A milling tree integral to the reticle provides for a quick determination of the target's distance, particularly in instances when the target is not intended to be engaged.

Abstract: A planar, T-shaped template member has a linear leg section with a first end thereof intersecting a cross bar section at a center thereof. The cross bar section has opposed ends, each end having a feature at a selected location therein. The cross bar section also has a circular aperture there through positioned opposite the leg section, with the circular aperture connected to an access channel extending to an edge of the cross bar section opposite the linear leg section. The linear leg section has a protrusion at a second end thereof opposite the cross bar section. The protrusion is sized to pivotally fit into the circular aperture and access channel of an identical T-shaped planar template member, thereby allowing pivotal movement between connected planar T-shaped template members. A large number of such templates can be connected together in a line.

Abstract: A manual measuring system (an articulated three-dimensional coordinate measuring machine or a gantry three-dimensional coordinate measuring machine) allows a measuring probe to be manually moved while enabling a user to focus on making measurements and allows the user to manually move the measuring probe in order to facilitate and accelerate measurements. The manual measuring system includes a sub-monitor (portable terminal) that is mounted near the tip of the measuring probe. It is possible to display on the sub-monitor a guided route for the measuring probe to a measurement point or to indicate on the sub-monitor that the measuring probe has entered a measurement allowable range or to allow the user to direct by means of the sub-monitor to obtain a measurement value by the measuring probe.

In an embodiment, a system comprises: a magnetic field sensor; a compensation coil placed at least partially underneath the magnetic field sensor; and a reverse current generator coupled to the compensation coil and to a power supply that is coupled to an electromagnetic interference (EMI) source, the reverse current generator operable to generate a reverse current in the compensation coil to generate a counter magnetic field for compensating the EMI.

Abstract: An aiming reticle comprising two primary characteristic feature sets consisting of a grid system and auxiliary crosshairs. The grid comprises horizontal crosshairs that are perpendicular to but do not intersect with a primary vertical crosshair. Omission of markings along the primary vertical crosshair and non-intersecting horizontal crosshairs provides improved target visibility along the vicinity of the primary vertical crosshair. The grid horizontal crosshairs are marked with intersecting major stadia lines, preferably at unit spatial intervals. The grid system further comprises self-contained crosses of predetermined size, within the space enclosed by the grid major stadia lines and grid horizontal crosshair separations to provide sub-unit reference in the vertical and horizontal reference.

Abstract: A multi-mode coordinate measuring machine system can be configured to measure coordinates in a variety of ways with a certain set of components. For example, an articulated arm coordinate measuring machine can measure coordinates on an object using a contact probe or a non-contact measuring device mounted on the articulated arm. Then, a user can remove the non-contact measuring device from the articulated arm coordinate measuring machine, and take additional measurements of the object that can be aligned with measurements taken by the articulated arm and devices attached thereto.

Abstract: A tool setting device includes a base body having longitudinally opposite base top and bottom surfaces laterally bounded by at least one base side surface.
