INTELLIGENT NETWORK OF WEARABLE MAGNETIC TX/RX TAGS FOR AUTONOMOUS LOCAL AND GLOBAL MONITORING AND RESUPPLY OF CONSUMABLE RESOURCES IN MOBILE UNITS
A system for autonomously managing resupply of consumable resources for a mobile unit includes sensors that monitor a level of a consumable resource for each entity in the unit. A network of tags communicates via short-range magnetic communications links. A local node provides a long-range RF communication link to communicate with a global node. Together the network of tags, local node and global node initiate a local resupply of the consumable resource to one or more entities from other entities within the mobile unit and a global resupply of the mobile unit from the one or more depots. The network of sensors/tags automates the task of monitoring resource levels and managing resupply. The use of the magnetic portion of the EM spectrum for local communications within the mobile unit overcomes the issues associated with RF in harsh or hostile environments.

EPITAXIAL GROWTH OF ALUMINUM ON ALUMINUM-NITRIDE COMPOUNDS
Apparatus and associated methods relate to forming an epitaxial layer of aluminum on an aluminum-nitride compound. The aluminum is epitaxially grown on the crystalline aluminum-nitride compound by maintaining temperature of a crystalline aluminum-nitride compound below a cluster-favoring temperature threshold within a vacuum chamber. Then, the crystalline aluminum-nitride compound is exposed to atoms of elemental aluminum for a predetermined time duration. The aluminum is epitaxially grown in this fashion for a predetermined time duration so as to produce a layer of epitaxial aluminum of a predetermined thickness. Such epitaxially-grown mono-crystalline aluminum has a lower resistivity than poly-crystalline aluminum.

An asymmetric ERA box improves the disruption of a shape-charge jet for a high-explosive projectile for a given mass requirement and stand-off distance. Mass is asymmetrically redistributed from the outer plate to the rear plate in the form of increased thickness of the rear plate. This is offset by forming the outer plate of a low-density material that provides an impedance mismatch sufficient to attenuate the shockwave of low velocity projectiles (e.g., 50 caliber bullets) so that they embed in but do not detonate the explosive. The outer plate provides negligible disruption of the shape-charge jet with substantially all the disruption being provided by the thicker high density rear plate. Placement of substantially all the mass toward the front of the shape-charge jet improves overall performance of the ERA. This asymmetric configuration provides the same performance as known symmetric ERA configurations against kinetic-energy projectiles as the total mass in the outer and rear plates remains essentially the same.

Vibration compensation is provided for Interferometric Noise Suppressed Oscillators (INSOs). In an INSO the error signal at the mixer output responds linearly to changes in carrier frequency. A vibration compensation signal is summed with the error signal at the input to the feedback amplifier to provide the control signal to the loop phase shifter to suppress close-in phase noise near the carrier frequency and to reduce the effects of mechanical vibrations on oscillator phase noise. The addition of the vibration compensation signal does degrade carrier suppression, hence increases the flicker noise contributed by the INSO's LNA but does so without degrading overall oscillator phase noise. In a frequency tuned configuration, the vibration compensation signal reduces the effects of mechanical vibrations on oscillator phase noise independent of the tuning voltage applied to the phase shifter.
