Analog Devices' iMEMS Accelerometer Improves Accuracy of Omron's Portable Digital Blood Pressure Monitors.Business Editors/High-Tech Writers NORWOOD, Mass.--(BUSINESS WIRE)--May 22, 2003 ADI's iMEMS accelerometer accelerometer Instrument that measures acceleration. Because it is difficult to measure acceleration directly, the device measures the force exerted by restraints placed on a reference mass to hold its position fixed in an accelerating body. improves blood pressure measurement accuracy by enabling wrist-height guiding function Analog Devices Analog Devices (NYSE: ADI) is an American multinational producer of semiconductor devices. Analog specializes in ADC, DAC, MEMS, and DSP chips for consumer and industrial goods. Analog is presently designing circuits in the 65 nanometer to 3 µm process feature sizes range. Inc. (NYSE NYSE See: New York Stock Exchange : ADI), the leader in MEMS (MicroElectroMechanical Systems) Tiny mechanical devices that are built onto semiconductor chips and are measured in micrometers. In the research labs since the 1980s, MEMS devices began to materialize as commercial products in the mid-1990s. technology for over a decade, today announced that its iMEMS(R) accelerometers have been adopted by Healthcare Business Company, Omron Corporation for its new portable digital blood pressure monitoring devices. The HEM-6371T is Omron's first portable digital blood pressure monitor to use ADI's iMEMS ADXL202E accelerometer. The ADXL202E enables an exclusive wrist-height guiding function to improve measurement accuracy. Since its introduction in Japan and the US during 2002, the HEM-6371T has become very popular in the home-use medical equipment market. "Omron selected Analog Devices' accelerometers because their proven performance and tilt sensing capability will help reduce measurement errors," said Mr. Yutaka Kobayashi, healthcare Company Products Strategy HQ Business Management Department, Division Manager, Omron Corporation. "We are forecasting tremendous demand for our very accurate, portable, easy-to-use, wrist blood pressure monitors." "This new product offering from Omron is a great example of how Analog Devices' iMEMS accelerometers are used by our customers to deliver value-added product features to consumers," said Paul Ganci, product line director, Micromachined Products Division, Analog Devices. "We are pleased to be able to offer to Omron these advanced inertial sensors using the same technology that ADI has used to produce more than 100 million integrated accelerometers with proven world class quality and reliability." Although conventional wrist style blood pressure monitors were easy to use, they often produced inaccurate measurements due to incorrect arm positioning. Using ADI's ADXL202E accelerometer, Omron's HEM-6371T offers a new feature that enables accurate tilt measurements of the user's arm relative to the body so that the arm is correctly positioned at the height of the user's heart. In the HEM-6371T, the accelerometer senses the angle and height of the users elbow and starts measurements only after the wrist is set at the right position. If the elbow moves during the measurements and the wrist shifts out of the proper position, the measurements are automatically stopped.

About the ADXL202E The ADXL202E is a dual axis, plus/minus 2 g (at full-scale) accelerometer with analog and PWM (Pulse Width Modulation) A modulation technique that generates variable-width pulses to represent the amplitude of an analog input signal. Like its fixed-width pulse density modulation (PDM) cousin, the output switching transistor is on more of the time for a outputs that can measure both dynamic acceleration (e.g. vibration) and static acceleration (e.g. gravity). The accelerometer integrates moving microscopic silicon parts and sophisticated signal conditioning Imagine feeding the output of a temperature sensor, which is in millivolts, to an Analog-to-digital converter to be processed. Is it possible for the Analog-to-Digital converter to process such a minute voltage amplitude? The answer is probably no. to produce a complete two-axis accelerometer on a single monolithic IC and features lower power requirements (300 microamps per axis at 5 V operation) than any accelerometer in its price range. The typical noise floor is 200 micro-g per rt-Hz at 5 V operation and allows signals below 2 milli-g to be resolved for bandwidths below 60 Hz. The ADXL202E is packaged in a 5 mm x 5 mm x 2 mm 8-lead hermetic hermetic /her·met·ic/ (her-met´ik) impervious to air. her·met·ic or her·met·i·cal adj.

About Analog Devices' Leadership in MEMS Technology As a pioneer in the micromachined IC industry, Analog Devices patented iMEMS technology was the first to produce a fully-integrated, single chip MEMS-based accelerometer in 1991. Since then, Analog Devices has maintained its leadership and remains the industry's only high-volume producer of single-chip accelerometers, having shipped more than 100 million units to date. Designed initially for use in safety-critical front and side impact airbag applications, iMEMS accelerometers provide complete cost-effective sensing solutions useful in a wide variety of other inertial sensing applications.
