HD Medical Group Selects Single-Chip Digital Filtering Solution From Quickfilter Technologies for Cardiac Anomaly Indicator
Quickfilter Technologies, Inc. announced today that HD Medical Group Limited, an innovative supplier of proprietary and patented heart sound technology, has selected its 4-channel programmable signal converter, designated the QF4A512, for use in its ViScope 100 cardiac anomaly indicator.
The ViScope 100 is similar in size and shape to a PDA and allows physicians to detect anomalies relating to the mechanical functioning of the heart. It has a unique visual display which allows the physician to see the heart sounds as waveforms and pick-up anomalies at the point of care. The unit functions on a Li-ion battery similar to the one used in mobile phones. A fully charged device can function continuously for up to eight hours making it ideal for screening large numbers of patients.
Announced in December 2005, the QF4A512 Programmable Signal Controller and QuickfilterPro4A Software allow systems designers to quickly and easily add precision digital filtering to an application. The chip provides an integrated solution including four channels of analog acquisition, on-board analog-to-digital conversion, anti-aliasing filters, programmable gain and FIR filtering. The entire device is reprogrammable and can be controlled via a simple microcontroller. Combined with a wireless controller, the device makes implementing a wireless sensor node extremely easy and effective.
"The Quickfilter QF4A512 provides a single integrated solution for handling four channels of data acquisition, programmable gain and digital filtering," explained Damon Coffman, Chief Technical Officer of HD Medical. "This easy-to-use solution gave us the ability to deliver a product which is both high performance yet simple to use."
"The HD Medical ViScope 100 provides unique affordability and availability to areas of the world in critical need for quality, early stage diagnosis of heart ailments," said Don DiDonato, Quickfilter's Vice President of Worldwide Sales. "Our technology enabled the customer to design a full-featured yet small and highly affordable product."

About Quickfilter Technologies
From Concept to Product in Minutes, not Days
Quickfilter Technologies, Inc utilizes patent pending techniques for implementing a programmable IC that allows an engineer to design a custom circuit for signal processing without the cost and complexity of programming a DSP. Using the Quickfilter solution, it is possible to create and begin operating a custom four-channel analog front end, digital converter and multi-stage digital filter in less than five minutes. Quickfilter's products are ideally suited for sensors in industrial monitoring and control, medical equipment, homeland security, and engine control applications.
The Quickfilter solution comprises over a dozen individual component functions, both analog and digital, into a single integrated circuit (IC) that is programmable using Quickfilter software. This enables customer to rapidly complete a design at significantly lower cost and higher performance. In addition, the IC can be reprogrammed in circuit during design, at the time of shipment or in the field.
Quickfilter Technologies Inc. is a private equity funded fabless semiconductor company founded in 2003 by Bob Silco and located in Allen, Texas. The company is developing a family of programmable mixed-signal integrated circuits that convert noisy analog signals into clean, usable digital signals.
