Data Acquisition Module

ADLINK Technology (San Jose, CA) announced the USB-1210 USB 2.0 data acquisition module that supports four 16-bit channels of simultaneous sampling at up to 2 MS/s per channel, and ensures zero data loss in long-term data acquisition by way of 256- MS deep onboard FIFO (First In, First Out). The 4-channel USB DAQ with simultaneous sampling delivers -100 dB THD and 14.3-Bit ENOB (effective number of bits) at up to 2 MS/s. Up to 16-sec. data buffer enables long-term data acquisition and recording at full speed (2 MS/s), preventing data loss from slow CPU response under heavy system loading. Built-in precision reference voltage for autocalibration eliminates the need for external instruments. It supports external digital/analog trigger source and flexible trigger modes, and 500 VDC isolation protects the connected computer from hazardous voltage caused by improper signal connection.

Temperature Scanner Indicators

The Sensor Connection, a division of Harold G. Schaevitz Industries LLC (Troy, MI), offers the model PMD-MXT temperature scanner indicator. The 32-channel microprocessor-based temperature scanner provides continuous monitoring of up to 32 channels of thermocouple or RTD sensors. The 14-mm-tall digit-red LED display is easy to read at a distance. Rows of LED annunciators warn of specific channel alarm conditions. The scanner has two user-selectable HI/LO, HI/HI, or LO/LO alarm set points, configured through front panel pushbuttons.

Data Acquisition Card

Innovative Integration (Simi Valley, CA) introduced Atropos, an XMC I/O module with low-noise clock generation and distribution for data acquisition and communications timing applications. The module has four output clocks and four output triggers, as well as a clock/reference input and a trigger input. Multiple cards can be cascaded to synthesize dozens of phase-synchronous, ultra-low-jitter clocks and triggers within radar, beam steering, and MIMO applications. In the sample clock generation mode, the card can generate clocks from 74.06 to 3080 MHz. All clock outputs may be referenced to an on-card 280-ppb temperature-compensated oscillator, or an external clock input. In distribution mode, a supplied clock and trigger are buffered and distributed 1:4. The PLL circuit is fully programmable. Example code supports control of all card features. Software tools for host development include C++ libraries, and drivers for Windows and Linux.

Detection Scanner

The R2000 Detection laser scanner from Pepperl+Fuchs (Twinsburg, OH) features a 360-degree gapless measurement angle with angular resolution within 0.071 degrees, scan frequency to 30 Hz, and object detection to 1 mm. An eye-safe visible red laser enables alignment and detection of very small objects or reflectors. The scanner can detect objects up to 10 m away and reflectors up to 30 m away, with measurement repeatability within 12 mm of true distance value. The scanner is suited for detecting protrusions or obstacles over a large area, collision avoidance on overhead monorails, detecting small overhangs such as damaged pallets, monitoring entryways and exits, controlling the height of pallets on palletizers, and verifying empty, full, or overfilled cartons on conveyors. The IP65 rated scanner has an anticipated operating life of 20 years in operating temperatures from -10 to 50 °C, and offers four digital I/O channels that can each be configured as an input or as an output (NPN or PNP).

Improving Medical Devices with Force Sensing Technology

This white paper explores the exciting new trend toward designing smart medical devices that provide critical force feedback to eliminate guesswork, improve outcomes, and increase consistency. Technical topics covered include the unique advantages of force sensing resistor technology over traditional technologies such as strain gauges and load cells. These advantages include simpler electronics, wider dynamic range, ease of integration, and lower cost. The white paper highlights how thin and flexible sensors have enhanced a wide range of medical device applications by providing force feedback and making the products smart.

Wearable Nanowire Sensors Monitor Electrophysiological Signals

Researchers from North Carolina State University have developed a new, wearable sensor that uses silver nanowires to monitor electrophysiological signals, such as electrocardiography (EKG) or electromyography (EMG). The new sensor is as accurate as the “wet electrode” sensors used in hospitals, but can be used for long-term monitoring and when a patient is moving.

Mini Solar Observatory Can Be Used on Manned Spacecraft

Southwest Research Institute (SwRI) developed a miniature portable solar observatory for use onboard a commercial, manned, suborbital spacecraft. The SwRI Solar Instrument Pointing Platform (SSIPP) uses a classic, two-stage pointing system similar to larger spacecraft, but in this case, the first stage is a pilot who initially steers the instrument toward the Sun. SSIPP does the rest, locking onto the Sun to allow observations. The first SSIPP spaceflight will search for “solar ultrasound,” a phenomenon first observed in the early 2000s by the Transitional Region and Coronal Explorer (TRACE) spacecraft. The ultrasound is sound waves with a 10-second period, some 18 octaves deeper than ultrasound on Earth, and forms visible ripples in the Sun’s surface layers. The waves are difficult to detect without space instrumentation because the tiny, rapid fluctuations cannot be separated from the confounding influence of Earth’s turbulent atmosphere. Although at first SSIPP will be operated from inside the cockpit, a full system eventually will be mounted outside the host vehicle to enable UV and X-ray observations that are inaccessible from the ground.
