Graphene-Based Sensor for Improved Evaluation, Diagnosis, and Treatment of Asthma

This device detects and measures inflammation in the lungs.

Asthma, which causes inflammation of the airway and obstructs airflow, affects about 300 million people worldwide. Symptoms include coughing, wheezing, shortness of breath, and chest tightness. Other serious lung ailments include chronic obstructive pulmonary disease (COPD), which encompasses emphysema and chronic bronchitis.

Artificial “Wrist” Enables Design of Wearable Blood Pressure Monitors

This wearable device monitors blood pressure continuously, 24 hours a day.

Unfortunately, blood pressure (BP) measurements currently require the use of a cuff that temporarily stops blood flow. A wearable BP “watch” using today’s technology would squeeze the wrist every few minutes, making it impractical to use. A better method might gauge subtle pressure changes at the surface of the skin above one of the main wrist arteries — the radial artery — without regularly cutting off circulation. But before this new technology can be developed, there is a need to understand what the pressure inside a blood vessel looks like on the surface of the skin. This requires a physical model that can be used to test wearable devices in a laboratory.

Digital-to-Analog Transformation and Reconstruction of ECG Data

This technology allows rapid, automated, second interpretation of 12-lead ECG data.

The innovators at NASA Johnson Space Center have developed a new method and device for specialized digital-to-analog conversion (DAC) and reconstruction of multichannel electrocardiograms (ECGs), including 12-lead ECGs. Current devices do not have the functionality that allows for the transmission of stored digital ECG data collected from one manufacturer’s ECG machine to another for an automated second opinion. With this technology, the physician has the opportunity to compare results by transferring the ECG data to another ECG machine — regardless of location — when a patient’s results are difficult to interpret for a second opinion. The technology also allows for the use of less expensive 12-lead ECG front ends or analog-to-digital conversion (ADC) hardware that is advantageous when in remote locations or with patients who are mobile during research studies. The digital-to-analog transformation and reconstruction of ECG data technology is available for licensing.

Miniaturized Chemical Detectors for Point-of-Care Diagnosis

Applications include disease biomarkers and diagnostics, monitoring wound health for infections, and exposure to bacteria, viruses, and toxins.

This chemical detector, based on a miniaturized, pulse-discharged ionization detector (mini-PDID), makes it possible to diagnose illnesses by identifying volatile organic compounds (VOCs) associated with certain diseases and infections on a patient’s breath, or in the headspace of biological fluids.

Removing the Risk of Concentrated Salt Solutions to Precision Dispense Pumps

IVD instrument OEMs require high accuracy pumps for dispensing reagents, wash fluids and samples. The types and concentrations of fluids dispensed by these pumps vary widely and can be excessively damaging to the internal parts of pumps. For this reason, pump designers are continually challenged to create products that can survive increasingly aggressive environments.

Personalized Healthcare Calls for Innovative Wearables and Medical Devices

Because the world population is aging, chronic diseases are on the rise and healthcare costs are reaching unsustainable heights, it is essential to detect pathologies early. The Internet of Things (IoT) is now poised to transform the healthcare industry by providing wireless connectivity and sensing. Body-worn electronics and implanted devices, equipped with tiny sensors that continuously monitor vital parameters and securely report anomalies to appropriate physicians, will improve patients’ quality of life while delivering timely medical help. Personalized healthcare is making medicine participatory, personalized, predictive and preventive (P4 Medicine). Medical device and high-tech companies are joining forces to satisfy a growing demand that might reach 20 billion medical connected devices by 2020. Successful medical device and pharmaceutical companies are using engineering simulation to develop systems that ensure high reliability, provide data privacy and achieve regulatory compliance quickly. Learn how platform-based engineering simulation maximizes the IoT opportunities for personalized medicine.

DESIGNING A VISION SYSTEM: A Comprehensive Guide to the Technical Requirements for Building a Vision System for Your Unique Imaging Application

There are a number of factors that need to be considered when designing a vision system, including: the hardware platform, the operating system, the software and API, and the very things that make the vision system “see” – the camera and its lens. Although each aspect plays an important role in achieving desired results, the camera and lens are the essence of the vision system. As such, it is recommended that both the camera and the lens be selected as a pair based on overall system requirements. Here we discuss various elements of vision systems with a focus on the camera and lens.
