Abstract: Various implementations are disclosed for self-contained, non-intrusive data collection in ammunition. In some implementations, a gun is loaded with a non-explosive, non-firing round of ammunition containing a data acquisition system. Such a data-collecting round of ammunition may be loaded into the gun according to the same procedures as live rounds of ammunition, and, in particular, may be loaded into a firing position immediately after a preceding live round has been fired. In this way, the data-collecting round of ammunition is able to experience temperature or other conditions that are experienced essentially identically by live rounds. After collecting related data while in the firing position, the data-collecting round may be removed from the gun, for analysis of the data for, for example, development of hot gun misfire safety procedures.

Abstract: A shock-triggered warhead fragment transmitter is described. The transmitter is designed to radiate a pulse upon either detonation of the warhead or impact of the fragment with the target. The pulse energy is obtained by shock de-poling of a ferroelectric material and is radiated using a dipole antenna. Detection of the radiated pulses may be used to confirm detonation of the warhead and determine the time and location of the detonation and facilitate battle damage assessment.

Abstract: A device is provided for holding and releasing a missile within a canister. The device includes a housing attached to the canister, a latch mechanism extending from the housing into the canister, a tension applier disposed in the housing to restrain the missile in the canister, a release mechanism disposed on the housing, an interface mechanism and a compression applier. The tension applier forces the latch mechanism against the housing to withdraw from the missile. The interface mechanism initially couples the release mechanism and the tension applier. The compression applier anchors to the interface mechanism and forces the latch mechanism against the housing to engage the missile and counteract said tension applier. On command, the release mechanism disengages from the housing to release the compression applier from the interface mechanism. This action enables the tension applier to withdraw the latch mechanism from the missile.

Abstract: Imaging systems may include a light source that directs light towards a scattering medium. A digital imaging system receives transmitted light that is transmitted through the scattering medium substantially without being scattered, and also receives multiple components of scattered light that are passed through the scattering medium after being scattered.

An imaging controller determines a property of the scattering medium, based on spatial correlations related to the image intensity information.
