Abstract: An assembly process is described for producing an ordnance projectile wherein the projectile maintains a compressive force on an explosive body carried therein throughout an anticipated operational temperature range. The process includes raising the temperature of the hollow projectile body to an elevated temperature, cooling the explosive body to a temperature below a lowest anticipated operating temperature of the projectile, nesting the cooled explosive body within the hollow projectile body while the projectile is at the elevated temperature, securing the explosive body and the hollow projectile body together, and normalizing the temperature of the nested bodies by allowing them to come to a common temperature, typically room temperature. Different thermal expansion characteristics of the inner and outer bodies will result in the projectile maintaining a compressive force on the explosive body at normal temperatures.

Abstract: A method and a device can measure machine error of an axis of rotation in a tool post having a touch probe without restriction of an angular range of an angle of rotation. Directions of a measurement plane and a measurement axis in a five-axis measurement are switched in correspondence to a range of the angle of rotation in a touch probe.

The five-axis measurement is carried out, for example, by setting the measurement plane to a position which is perpendicular to a line connecting an estimated center of the reference sphere and a center of a tip sphere or the lever rod of the touch probe.

Abstract: Determining the physical location of wirelessly connected devices within a network can provide a number of security benefits. However, manually determining and configuring the physical location of each device within a system can be burdensome. To ease this burden, devices within a network are equipped with a location detection sensor that is capable of automatically determining a device's location in relation to other devices within the network. A location detection sensor (“sensor”) may include a light source, a light direction sensor, a rangefinder, and a radio or wireless network interface. Two location detection sensors can perform a location detection process to determine their relative locations to each other, such as the distance between them. As more sensors are added to a network, a sensor management system uses the relative locations determined by the sensors to map the sensors to a physical space layout.

Abstract: A navigation system comprises a base system and at least one correction system, wherein the base system and the correction system each capture measured values. The measured values describe navigation data and are each burdened with error values. The error values describe discrepancies in the measured values from the described navigation data. The error values of the measured values of the base system are recognized by the measured values of the correction system.

The adaptation of the parameters is chosen on the basis of the capture uncertainty in accordance with a characteristic curve or a family of characteristic curves.
