Communications in Space: A Deep Subject

Transmitting and receiving radio signals between spacecraft in deep space is a snap compared with getting those signals back to Earth, especially when the spacecraft is 120 billion miles away.

General Micro Systems Inc. (GMS) recently announced that the U.S. Army will exclusively deploy powerful rugged server and display systems from GMS to run the multifunction video display (MVD) software within Type II medium mine protection vehicles (MMPV). The GMS system comprises four components – two chassis and two displays. It also includes an enterprise-class, ultra-rugged, secure server with an intelligent 12-port 1/10 Gigabit Ethernet switch, a router, mass-media storage, CITV/DVR, video-over-IP, and two ultra-thin, rugged smart-panel PCs. When coupled with a video encoder, the system is a complete full motion video and control system with storage.

The use of unmanned aerial vehicles (UAVs) is one of the most significant technological developments in the last decade. However, where once such equipment was unique to military operations, the use of a new generation of small and cheap to buy UAVs has spread exponentially. This brings a new dimension to contemporary terrorism, with those determined to do harm, seeking different ways of carrying out attacks on civilians.

Designing for Compressive Sensing: Compressive Art, Camouflage, Fonts, and Quick Response Codes

Compressive sensing (CS) is a relatively new field that has caused a lot of excitement in the signal processing community. It has superseded Shannon's time-honored sampling theorem, which states that the sampling rate of a signal must be at least twice its highest frequency. In CS, the necessary sampling rate depends on the sparsity of signal, not its highest frequency, reducing sampling requirements for many signals that exhibit natural sparsity. This compression happens on the hardware level, allowing systems to be designed with benefits ranging from increased resolution and frame rates to decreased power consumption and memory usage. Despite this enthusiasm for CS and the large quantity of research being performed, the number of commercial systems that use CS is relatively few. The problem of designing a CS strategy that increases functionality while actually reducing overall system cost has not been solved in many areas. This is a developing field where not only are new applications for CS still being developed, but also fundamental aspects of CS theory are still evolving.

Calculation of Weapon Platform Attitude and Cant Using Available Sensor Feedback

When firing artillery, there is typically a maximum angle that the platform cannot exceed relative to the Earth plane. This is due to the large recoil forces involved and the risk of destabilizing the platform the weapon is mounted to. Mobile systems are particularly sensitive to this as the attitude of the platform relative to Earth is constantly changing. A simple solution is to add pitch and roll sensors directly to the platform. However, many mobile systems already have an assortment of sensors that can be used to calculate the platform attitude.

Validation of Automated Prediction of Blood Product Needs Algorithm Processing Continuous Non-Invasive Vital Signs Streams (ONPOINT4)

Hemorrhagic shock occurs frequently in natural and man-made disaster scenarios. To control bleeding and to provide necessary resuscitation, swift and accurate diagnosis and decision-making are required. Early recognition of bleeding and the need for targeted interventions could improve both survival and resource management, allowing the receiving hospital to prepare required blood, surgeons, or other resources in advance of patient arrival and to conserve valuable resources in those patients who are not bleeding. Resources can be saved through avoidance of over-triage, thereby reducing unnecessary air transport, unnecessary blood transfusions, and unnecessary evaluation with labs, X-rays, and computed tomography scans, which is important in all resource-constrained and austere environments.
