Nano-Pervaporation Membrane With Heat Exchanger Generates Medical-Grade Water

A small system produces high-quality water using a heat exchanger that meets requirements for evaporation of substances such as pharmaceuticals and vitamins.

A nanoporous membrane is used for the pervaporation process in which potable water is maintained, at atmospheric pressure, on the feed side of the membrane. The water enters the non- pervaporation (NPV) membrane device where it is separated into two streams — retentate water and permeated water. The permeated pure water is removed by applying low vapor pressure on the permeate side to create water vapor before condensation. This permeated water vapor is subsequently condensed by coming in contact with the cool surface of a heat exchanger with heat being recovered through transfer to the feed water stream.

Wireless Brain Implant Using a Telemetric Electrode Array System

A 3D intra-cortical electrode array is embedded for signal acquisition, processing, and wireless communication.

The ability to monitor the activities of ensembles of single neurons is critically important in understanding the principles of information processing in the brain that underlie perception, cognition, and action. Multiple microelectrode recording using appropriate neuronal implants provides this ability. The Telemetric Electrode Array System (TEAS) project aims at developing and embedding a three-dimensional intra-cortical electrode array with all electronics required for signal acquisition, processing, and wireless communication entirely into the head.

Digital Wound Measurement and Tracking System

This Web-based platform tracks, documents, and measures the efficacy of wound treatments.

Historically, the subjective nature of wound treatment has lead to many trial-and-error therapies to match wounds with the right treatment. The WoundMatrix™ digital wound measurement and tracking system provides an objective and qualitative tool and method to track, document, and measure the efficacy of wound treatments.

Spiralock Fasteners Safeguard Reliability for Medical Lasers and Implants

Failure is not an option when it comes to medical equipment. From critical or sensitive devices like lasers, MRI scanners, knee joints, and implantable pacemakers to instruments as straightforward as stethoscopes, when life is at stake, medical equipment must be reliable.

Mass Flow Controllers Ensure Astronauts Have Medical Fluids On Demand

Quantim Coriolis mass flow controller Brooks Instrument Hatfield, PA 215-362-3527 www.brooksinstrument.com

Transporting medical fluids that are manufactured on Earth into space is expensive and logistically challenging, so researchers at NASA’s Johnson Space Center sought a way to manufacture medical fluids in space. The Quantim Coriolis mass flow controllers from Brooks Instrument were chosen by NASA contractor ZIN Technologies for measuring water flow through a purification system to a standard IV bag that was prefilled with salt crystals and a magnetic lab stirrer. The Quantim devices are making their way into space to ensure that astronauts have medical fluids on demand for emergency needs.

Omron Controls and Drives Improve Animals’ Joint Health

Ferno Aquatic Therapy, Wilmington, OH, designs and manufactures canine and equine underwater treadmill equipment used by veterinarians to provide aquatic therapy, rehabilitation, and conditioning for both dogs and horses. Designed specifically for canine rehabilitation, the Ferno Aqua Paws Plus Under water Treadmill System allows dogs to begin the rehabilitation process earlier than normal. Using the buoyancy, resistance and heat properties of water, the Aqua Paws unit creates a low-impact treadmill workout that helps the animal to increase muscle strength and endurance, providing the foundation for a quicker transition to land-based therapy.

Biomedical Wireless Ambulatory Crew Monitor

A compact, ambulatory biometric data acquisition system has been developed for space and commercial terrestrial use. BioWATCH (Bio medical Wireless and Ambulatory Telemetry for Crew Health) acquires signals from bio-medical sensors using acquisition modules attached to a common data and power bus. Several slots allow the user to configure the unit by inserting sensor-specific modules. The data are then sent real-time from the unit over any commercially implemented wireless network including 802.11b/g, WCDMA, 3G.

Three-Dimensional Optical Coherence Tomography

Advantages over prior OCT systems include less bulk and greater speed.

Three-dimensional (3D) optical coherence tomography (OCT) is an advanced method of noninvasive infrared imaging of tissues in depth. Heretofore, commercial OCT systems for 3D imaging have been designed principally for external ophthalmological examination. As explained below, such systems have been based on a one- dimensional OCT principle, and in the operation of such a system, 3D imaging is accomplished partly by means of a combination of electronic scanning along the optical (Z) axis and mechanical scanning along the two axes (X and Y) orthogonal to the optical axis.

Isolation of Precursor Cells From Waste Solid Fat Tissue

A process for isolating tissue-specific progenitor cells exploits solid fat tissue obtained as waste from such elective surgical procedures as abdominoplasties (“tummy tucks”) and breast reductions. Until now, a painful and risky process of aspiration of bone marrow has been used to obtain a limited number of tissue-specific progenitor cells.
