Tactical Medical Coordination System

The term "tactical medical coordination system" (TacMedCS) denotes any of several prototype electronic systems for tracking patients in a scenario that may involve multiple instances of treatment by different medical personnel in different locations. The TacMedCS was conceived as a means of facilitating coordination of care of military personnel injured in combat and/or facilitating coordination of care of victims of large-scale disasters. The most advanced prototype has already been demonstrated to be effective in operations at a Navy fleet hospital.

Remote Blood Pressure Waveform Sensing

This non-contact, non-invasive blood pressure apparatus continuously measures and monitors blood pressure using a laser Doppler vibrometer to create waveforms. The laser-based system may be utilized to continuously provide highly detailed information about the timing characteristics of the blood pressure waveform. The system does not require elaborate adjustments of one or more lasers and laser detectors so it may be quickly utilized. The system takes measurements from a subject when the subject is moving.

Robot Vision System for Precise Object Retrieval in Unmanned Systems

Automating large-scale material handling systems that involve picking up or retrieving items via cranes or robot arms can yield big benefits, particularly in harsh or hard-to-access environments. The Automatic Launch & Recovery System (AutoLARS) is being developed for the U.S. Navy by Allied Systems and Concept Systems. The Navy required a system for retrieving unmanned vessels and placing them aboard Navy ships. The problem is how to guide a robot that is affixed to a ship so that it can attach a line or fixture to an unmanned floating vehicle, and how to accomplish this while both are tossing at sea.

Advanced Concepts for Space Access

A paper summarizes commonly proposed advanced launch concepts, including both concepts that employ propellant and propellant-less concepts. A wide range of advanced launch concepts have been proposed in an effort to revolutionize space access through either a significant reduction in launch costs or significant improvements in launch performance. These revolutionary concepts aren't necessarily required to be in the propulsion arena. For example, materials that can dramatically reduce the inert mass fraction will also aid in a launch vehicle's ability to place more payload into orbit with existing propulsion systems.

Explicitly Timed Authorization Logic

A document describes explicitly timed authorization logic (nicknamed "η-logic"). In prior authorization logics, it is, variously, impossible or difficult to handle time explicitly; express security policies that involve complex, time-dependent relationships; or reason accurately about time. By enabling explicit mention of time, η-logic makes it easier to reason about time-dependent consequences of policies.

Emerging Power and Energy Technologies for Portable Electronics

A report discusses data obtained for the Navy's Special Operations Command (SOCOM), which seeks a portable power/energy source capable of providing sufficient power and energy for complex missions at a minimal weight penalty. The report focuses on the specific energy of systems, defining the weight of the power/energy system that must be carried by the soldier.

Using RFID to Protect System Firmware

Breeching the security of safety- or security-intensive products such as auto parts, set top boxes, military electronics, or smart batteries can be a lucrative business that is well worth the nominal investment required to create lookalike packaging and labeling, or to change the system firmware to allow unpaid access to licensed content. Because the counterfeiter does not incur any of the costs associated with product development, he quickly covers his capital investment at the expense of the authentic product manufacturer or service provider.

Board Versus Box: The Age-Old DAQ Dilemma

Since the beginning of PC-based data acquisition and control in the 1980s, one question has remained a constant consideration for all who would specify a new DAQ system. Is this application better served by an external I/O "box" connected to the PC via some communications link, or an internal "board" system plugged into a slot within the computer? If anything, this question has become more complicated as technology has progressed.

Adopting Aerospace Development and Verification Standards for Software

An ever-increasing reliance on software control has meant that many companies from non-aerospace business sectors (automotive, nuclear power, MRI scanners, financial systems) that do not have a traditional requirement for sophisticated software development processes now find themselves compelled to undertake safety-critical and safety-related analysis and testing. With the need for increased software quality across different industries, a tendency has emerged for companies to look outside their own market sector for best practice approaches, techniques or standards. Examples of such industry crossover have been seen in the automotive and avionics industries with the adoption of elements of the DO-178B standard by the former and a similar adoption of the Motor Industry Software Reliability Association (MISRA) standards by the latter.

Seven Practical Steps for Designing Networking Enclosures

The design of enclosures to house networking servers and components should be guided by one overriding concern — heat. Servers, in particular, generate a great deal of heat, so an enclosure must be capable of dissipating that heat to ensure that the components deliver their expected life.
