FreEnt Technologies, Inc. (FreEnt) and Johns Hopkins Universitys Applied Physics Laboratory (APL) are proposing a multiple-hit detection sensor called the Optical Lethality Measurement System (OLMS). This system is based on the Planar Optical Penetration Sensor (POPS) technology (originally developed and patented by APL) and prior art associated with the Blast Initiation Detector (BID). The BID is ...

Next-generation missile defense systems will utilize infrared sensing technologies that will require efficient cooling at low temperatures. We propose to develop an innovative solid-state cryocooler that can provide cooling at temperatures below 35 K while rejecting heat at temperatures up to about 300 K. The cooler uses compact, efficient electrochemical compressors with no moving parts to enha ...

Terrorist use of radioactive nuclear materials via nuclear and/or radiological dispersion devices (dirty bombs) is a serious threat. Therefore, it is crucial to detect proliferation of nuclear material. Critical challenges include: (a) high sensitivity detection of signature emissions from radioactive isotopes, and (b) cost-effectiveness for deployment of sensor networks across large storage facil ...

Hypersonic missile defense systems are being designed to reach global threats. During flight, external surfaces are predicted to reach temperatures in excess of 2200C. As a result, innovative, high performance thermal protection systems (TPS) are of great demand. Among ultra-high temperature ceramics (UHTC), it is well known that ZrB2- and HfB2-based materials have high melting temperatures and ...

Blast-induced Traumatic Brain Injury (TBI) is a major threat to the health of military personnel serving in modern theaters. As such, the biomechanical injury pathways of TBI are and have been the focus of many animal studies. However, differences in the experimental setups across laboratories make it difficult to draw definitive conclusions from the resulting data. A tool that can accurately e ...

Future MDA space missions will utilize small spacecraft with correspondingly small, advanced sensor systems. Cooling of these sensors is required to decrease detector noise and increase detector sensitivity by maintaining the detector at a reduced operating temperature. The cooling system comprises a mechanical cryocooler and its control electronics, both of which are critical technologies to enab ...
