PTC Heater Brings Greater Control for Hand-held Medical Devices and Disposables

Point of Care diagnostics devices, whether handheld or single-use, often require a brief application of tightly controlled heat. The disposable nature of these devices requires a low-cost component capable of delivering that heat reliably and safely. Heatron's new PTC heater solution uses a polymer-based heater technology that controls heat to within ±2°C of the target temperature, and reduces unit cost by eliminating sensors and applied controls.

High-Quality Tissue Formation Method

This technology could be used in research and development, pharmaceutical development, regenerative medicine, and drug screening and testing.

NASA's Johnson Space Center seeks interested parties for the commercialization of the High Density Spot Seeding (HDSS) method to create 2D and 3D tissue models. This method can potentially be used to develop tissue models for a variety of applications, including wound treatment, therapy, and tissue modeling of skeletal muscle, cardiac muscle, nerve, and bone. The HDSS technique has an easy four-step method that does not require expensive reagents, such as specialized serum or growth factors, and compared to traditional methods, HDSS has the potential to yield superior-quality tissue samples.

Filtering Molecules with Nanotube Technology

Innovators at NASA's Johnson Space Center have developed a filtration device to eliminate contaminants from water supplies. Originally developed to purify waste-water for reuse aboard the International Space Station, the innovation is applicable to numerous situations on Earth where there is a need to collect potable, medical-grade water from a contaminated water supply. The unique aspect of the technology is its use of acoustics, rather than pressure, to drive water through small-diameter carbon nanotubes. The invention requires less power than conventional filtration systems, and is well-suited to a variety of water processing needs.

3D Biomimetic Platform

This technology can be used for cell culture and drug discovery.

NASA's Langley Research Center has developed a method and apparatus to be used for cell culture that combines the effects of microgravity and low-dose radiation. The technology has been developed to simulate the effects of microgravity and chronic radiation exposure to cell culture experiments conducted on the International Space Station (ISS).

Automated Behavior and Cohesion Assessment Tools (ABCAT)

An important consideration of long-duration spaceflight operations is interpersonal dynamics that affect crew cohesion and performance. Flight surgeons have stated the need for unobtrusive monitoring to help detect if crews are having difficulties coping with long-duration spaceflight environments.

Algorithm Measures Range of Motion and Applies Eccentric and Concentric Loads During Exercise

Microprocessor-controlled exercise equipment that uses a servomotor has the capability to adjust the applied resistive load based on position, velocity, and acceleration. One method of applying the resistive load consists of applying a greater load during the eccentric phase of the exercise motion (muscles actively lengthening) than during the concentric phase of the motion (muscles actively shortening). This technique, called eccentric overloading, can improve the benefits of a strength training session significantly. Although the exercise device can alternate between concentric and eccentric loading based solely on the direction of the bar movement, this is undesirable for several reasons. First, when the velocity is close to zero, the system would rapidly switch between the eccentric and concentric loads. Second, if the exerciser is unable to complete a lift with the concentric load and wishes to lower the bar, the system would apply the high eccentric load, which is highly undesirable. Thus, it is necessary for the system to know the limits of the movement (range of motion, ROM) so that the system can identify when the user has completed the lift and the eccentric load can be properly applied.

Developing a Laser System to Decrease the Rate of Neurodevelopment Issues

A fairly new biomedical imaging modality, optoacoustic imaging is based on the use of laser-generated ultrasound. According to the National Center for Biotechnology Information, it is a hybrid method that has emerged over the past two decades, combining the high-contrast and spectroscopic-based specificity of optical imaging with the high spatial resolution of ultrasound imaging.

ECG Small Signal General and Analysis

Electrocardiogram (ECG or EKG) is the most common way to identify various ailments, especially when the ailment is related to the heart. To perform an ECG, the medical personnel places the leads on the patient’s skin. The leads measure the heart’s electrical activity of one heartbeat cycle and record it as a continuous line tracing on paper to produce a graph. The ECG signal may indicate:

SHAPE MEMORY ALLOY BASED SAFETY LATCH

Nicholas W. Pinto, Suresh Gopalakrishnan, Chandra S. Namuduri, Nancy L. Johnson, and Mark Vann General Motors, Warren, MI

General Motors has invented a device that indicates when an unsafe level of energy remains in an electrical panel box after the main power has been disconnected. Possible sources of this energy may be incorrect wiring, external device add-ons, and the presence of residual charge from capacitors. The device works by engaging a safety latch mechanism built with shape memory alloy (SMA) technology along with an audio or visual alarm.
