Oceana Sensor announces innovative wireless sensor network solution based on Quickfilter's QF4A512. "Adding Wireless to Sensors" The component is approximately the same size as 2 pennies end to end. The design of the WseM™ is a result of years of market investigation. WSeM™ uses current 802.11 wireless network infrastructures that are pervasive in most enterprises today. A WSeM™ contains an analog to digital converter/filter, an on-board processor, and 802.11 wireless communication capability all on one printed circuit board. It can accommodate up to four different sensor inputs. The WSeM™ is simple to implement into an existing product or incorporate into new product designs. The ease of implementation is due to the complete development package that consists of, configuration tools, sensor reference designs and full communications protocols. It is ready to communicate to existing access points, PCs, PLC’s and more. Oceana Sensor Module LLC’s solution also includes tools that allow the customer to retrofit a wired or wireless sensor product very quickly.
dspZONE Products for the week of September 24, 2007 features Quickfilter's audio crossover
"EN-Genius Says"… Being able to deliver a substantial chunk of signal processing power for under $3 opens the Quickfilter for use in some interesting applications including equalizing the response of headsets, handsets, and speakers as well as in digital microphones. Quickfilter says it’s currently involved with several more unusual products such as smart digital stethoscopes and providing digital crossover in wireless surround sound speakers. This versatile little chip is also finding lots of use in non-audio applications such as processing signals from detectors used in remote sensing to detect acceleration, vibration, or acoustic signatures. Other creative customers are using the QF1D512 to filter out noise in the strain gauges used in ultra-precise scales. I also see some significant potential for using it in things like digital IF processing and down-sampling. Copyright © EN-Genius Network Ltd.
Quickfilter mentioned in March 2007 Sensors and Transducers magazine article
"Data Acquisition and Digital Filtering for Infrasonic Records on Active Volcanoes" by José Chilo and Thomas Lindblad presents the design of a digital data acquisition system for volcanic infrasound records. The system includes four electret condenser element microphones, a QF4A512 programmable signal converter from Quickfilter Technologies and a MSP430 microcontroller from Texas Instruments. The signal output of every microphone is converted to digital via a 16-bit Analog to Digital Converter (ADC). To prevent errors in the conversion process, Anti-Aliasing Filters are employed prior to the ADC. Digital filtering is performed after the ADC using a Digital Signal Processor, which is implemented on the QF4A512. The four digital signals are summed to get only one signal. Data storing and digital wireless data transmission will be described in a future paper. Copyright © 2007 IFSA
Electronic Design Features "MSP-Mojo"
Electronic Design features the QF1D512-EZ430 "MSP-Mojo" board, a target board designed to interface with the TI ez430U development platform. The board features the Quickfilter QF1D512 SavFIRe chip coupled with the MSP430, which enables designers to add precision digital filtering to their MSP430 designs.

The White Paper "Intelligent Signal Processing at the Sensor Network Edge" is now available at the TechOnLine website.
Circuit Cellar Goes Under the Hood in "FIR Factor"
The March 2006 edition includes a 6 page article on the QF4A512 by Tom Cantrell. He discovered for himself just how easy it is to design and implement an application using the Quickfilter Dev Kit. He concludes, "..your brick wall filters will be the envy of designers forced to get by with lesser technology". (a pdf version is available for download and/or printing)
Programmable Analog Converter Yields Flexible Filters
The December 28th Planet Analog Newsletter featured the QF4A512. You can read the feature on the QF4A512 using the link above. Editor Bill Schweber said this about the chip, “Another interesting product is the QF4A512 four-channel Programmable Signal Converter from Quickfilter Technologies, which provides a signal path with antialiasing filters, A/D converter, and 512-tap FIR filters. Using this IC, designers can implement four independent filters with fully settable parameters, store them within the device, and even change them during operation. It's a good example of an application-focused, programmable analog function.”
