Compressed Sensing – The Latest Advances

Recently MIT announced the latest research in compressed sensing that may soon be saving us money for a wide range of imaging and signal-processing applications. Compressed sensing is a new technique in signal processing and imaging that takes a weighted linear combination of samples. Using simple linear equations, these few samples can represent the complete signal. [...]

Voler Helps Out With Legacy Test Equipment

Voler was recently approached by a large medical device company that relied on test equipment that had been designed several years earlier by a firm that was no longer available. They ask Voler for help because for the last two years the equipment would periodically fail calibration and was providing inconsistent results. They had done [...]

How to Avoid Big Errors Using Accelerometers

Accelerometers can be used to measure not only acceleration but also vibration. Historically, accelerometers have seen widespread use in manufacturing production lines and automotive electronics. They are now widely used in portable electronic devices such as cell phones, video game controllers, and cameras. Medical devices increasingly incorporate them to add capabilities to measure motion such as the rate and depth of chest compression.

Sensor Calibration Verifies Accuracy

FDA regulations for medical devices require manufacturers to develop and monitor production practices to ensure that the end device conforms to its specifications. A calibration program is a major part of this quality system to verify the accuracy and precision of measurements. Walt describes the techniques, tools, and equipment used to calibrate a disposable medical device.

Medical devices that rely on one or more embedded sensors not only need testing, but also sensor calibration. Digital circuits can be subject to pass/fail testing. However, sensors require precise testing or calibration to be accurate. Calibration ensures that different individual devices give the same result. Sensors needing calibration include temperature, pressure, acceleration, strain, and displacement.

Trends In Touch Screens

Touch screens are used in a rich variety of new products: cell phones, computer tablets, personal navigation devices, MP3 players, digital cameras, fitness equipment, security systems, point of sale systems, and kiosks. Examples of consumer devices using projected capacitive touch screens include Apple's iPhone and iPod. Touch screen displays A touch screen is a display [...]
