Mini-Sensor Measures Magnetic Activity in Human Brain

A recent study indicates that the technology may be used in magnetoencephalography (MEG), a noninvasive procedure that could advance the study of neurological diseases. A miniature atom-based magnetic sensor has passed an important research milestone by successfully measuring human brain activity. Experiments verified the sensor's potential for biomedical applications such as studying mental processes and advancing the understanding of neurological diseases.

Hands-Free Transcranial Color Doppler Probe

These probes enable full use of TCD technology for neurological diagnostics. Current transcranial color Doppler (TCD) transducer probes are bulky and difficult to move in tiny increments to search and optimize TCD signals. This invention provides miniature motions of a TCD transducer probe to optimize TCD signals.

Purifying, Separating, and Concentrating Cells From a Sample Low in Biomass

This fluorescence-activated cell-sorting-based approach has applications in operating room cleanliness validation assays, and in pharmaceutical development and quality assurance. Frequently there is an inability to process and analyze samples of low biomass due to limiting amounts of relevant biomaterial in the sample. Furthermore, molecular biological protocols geared towards increasing the density of recovered cells and biomolecules of interest, by their very nature, also concentrate unwanted inhibitory humic acids and other particulates that have an adversarial effect on downstream analysis.

Virtual Ultrasound Guidance for Inexperienced Operators

This audio/video system provides real-time help to inexperienced ultrasound operators in remote environments. Medical ultrasound or echocardiographic studies are highly operatordependent and generally require lengthy training and internship to perfect. To obtain quality echocardiographic images in remote environments, such as on-orbit, remote guidance of studies has been employed. This technique involves minimal training for the user, coupled with remote guidance from an expert. When real-time communication or expert guidance is not available, a more autonomous system of guiding an inexperienced operator through an ultrasound study is needed. One example would be missions beyond low Earth orbit in which the time delay inherent with communication will make remote guidance impractical.

Cloud-Based Product Lifecycle Management for the Medical Industry

A collaborative software solution offers medical OEMs a range of benefits, including more efficient product development, improved profitability, and higher product quality. The medical industry stands to benefit immensely from cloud-based product lifecycle management (PLM). The mountains of information that medical companies must manage when bringing a new product to market are truly massive. Every aspect of the product — and every change made to the product — must be carefully documented to ensure compliance with regulatory bodies such as the Food & Drug Administration (FDA) or the ISO (International Standards Organization).

High-Accuracy Closed Loop Force Feedback

Benefits of serial servo digital presses for force gauge specifications. Hand-driven press assemblies, which require a specific amount of force applied for a given amount of time, present challenges when attempting to accurately measure or replicate results in production or quality control processes. In contrast, servo-driven digital presses are able to provide accurate, consistent, and repeatable results while outputting trackable data. By controlling position and current, the servo-driven digital press allows for stable, accurate, and repeatable control.

Ultra-Sensitive Biosensor for Medical Diagnostics

This device may enable miniaturization and new point-of-care applications in doctors' offices. Researchers have created an ultrasensitive biosensor that could open up new opportunities for early detection of cancer and “personalized medicine” tailored to the specific biochemistry of individual patients. The device, which could be several hundred times more sensitive than other biosensors, combines the attributes of two distinctly different types of sensors, said Muhammad A. Alam, a Purdue Uni versity professor of electrical and computer engineering.
