Product of the Month: First Inductance-to-Digital Converter
Posted in Products, Manufacturing & Prototyping, Electronics, Electronic Components, Power Management, Medical, MDB on Friday, 01 November 2013
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.

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.

Circuit Protection Critical to Safeguarding Both Medical Devices and Patients’ Health
Posted in Manufacturing & Prototyping, Custom & Contract Manufacturing, Electronics, Electronic Components, Board-Level Electronics, Thermal Management, Power Management, Medical, Features, MDB on Sunday, 01 September 2013
Agrowing array of electronic devices are available to healthcare providers, patients, and their families, including glucose meters, blood pressure monitors, automated external defibrillators (AEDs), and many others. To ensure safe, reliable performance of these devices, their designers must factor in circuit protection requirements from the earliest stages of the circuit design process. For example, a seemingly minor electrostatic discharge could easily render a portable medical device useless if it’s not properly protected, exposing the patient to the danger of misleading (or no) readings and the device’s manufacturer to legal liability if inaccurate results lead to improper treatment.
