Wireless Foot Controls

Steute Meditech, Inc., Ridgefield, CT, announces its medical-grade, fully-compliant, wireless foot controls. Each customized unit features proprietary technology to achieve safe, interference-free performance. Operating in the ISM 2.4 GHz band, the technology continuously monitors the integrity of the bi-directional transmission path and ensures discrete device compatibility. A floor sensor protects against inadvertent operation.

Product of the Month: First Inductance-to-Digital Converter

Texas Instruments, Dallas, TX, unveiled the industry’s first inductance-to-digital converter (LDC), a new data converter category that uses coils and springs as inductive sensors to deliver higher resolution, increased reliability, and greater flexibility than existing sensing solutions at a lower system cost. Inductive sensing is a contactless sensing technology that can be used to measure the position, motion, or composition of a metal or conductive target, as well as detect the compression, extension, or twist of a spring. Applications for inductive sensing range from simple push buttons, knobs, and on/off switches to high-resolution heart rate monitors, flow meters, and high-speed motor/gear controllers.

Restoring Sense of Touch to Laparoscopic Surgeons

A small, wireless capsule has been developed by a team of doctors and engineers at Vanderbilt University, Nashville, TN, that, they say, can restore the sense of touch that surgeons are losing as they shift increasingly from open to laparoscopy or minimally invasive surgery.

Electron Beam Writer Enables Microfabrication

Integrated electronics could activate prosthetics. The new electron beam writer housed in the cleanroom facility at the Qualcomm Institute, previously the UCSD division of the California Institute of Telecommunications and Information Technology, is important for two major areas of research by Shadi Dayeh, PhD, an electrical and computer engineering professor. He is developing next-generation, nanoscale transistors for integrated electronics. At the same time, he is working to develop neural probes that can extract electrical signals from brain cells and transmit the information to a prosthetic device or computer. To achieve this level of signal extraction or manipulation requires tiny sensors spaced very closely together for the highest resolution and signal acquisition. Enter the new electron beam writer.

Heart Pump with Behind-the-Ear Power Connector

One-third of patients with heart pumps develop infection at abdominal connection. Cardiac surgeons and cardiologists at the University of Maryland Heart Center are part of a multi-center clinical trial evaluating the efficacy of powering heart pumps through a skull-based connector behind the ear. The pumps, called left ventricular assist devices (LVADs), support the heart’s main pumping chamber, the left ventricle. LVADs are implanted in the chest and powered with external batteries. Typically, these devices, which are used for patients with severe heart failure, are powered through an electrical cord connected at the abdomen, where potentially deadly infections can develop.
