Nanofabricated Devices Detect Ultrasound with Light

Tiny, soft, transparent, nanofabricated devices can be integrated into a contact lens.

The Micro-ring resonator detector can determine the speed of blood flow and the oxygen metabolic rate at the back of the eye. This information could help diagnose such common and debilitating diseases as macular degeneration and diabetes. The tiny, transparent device can fit into a contact lens, and could help a range of scientific endeavors from biomedicine to geology.

Bio-Detection System is a Handheld Chemistry Lab

The device miniaturizes bench-scale analyses in a handheld, low-power device.

Devices for manipulating fluids on the microscale have been developed to store, hold, and manipulate small amounts of fluids, and have been applied to the detection of analytes in sample fluids. Manipulating fluids and performing capillary electrophoresis in microfluidic devices promises advantages of small size, high throughput, low sample volumes, and low cost.

Product of the Month: July 2017

Tektronix, Beaverton, OR, introduced the TTR500 Series USB vector network analyzer, a USB-based RF test instrument. It includes VectorVu-PC analysis software and built-in bias tee for testing active devices. The 2-port, 2-path, S-parameter VNA features 100 kHz to 6 GHz frequency range, 122 dB dynamic range, less than 0.008 dB trace noise, and -50 to +7 dBm output power. The built-in bias tee allows for 0 to ± 24V, and 0 to 200 mA on both ports for active devices. The analyzer operates with any Windows PC or laptop, and VectorVu-PC software controls and calibrates the instrument. For automated test systems in design or manufacturing, the software offers programmatic support for SCPI commands, including command compatibility with common legacy VNAs for integration into existing test systems. In addition, the software offers an offline mode for data analysis with an output file format compatible with common EDA simulation tools. Accessories include a rugged carrying case, rack mount kits, phase-stable cables, attenuators, adapters, and calibration kits.

Impedance Measurement Box

This tool provides single-point measurement of batteries.

The dependability of energy storage devices — particularly batteries — is becoming increasingly important to consumers, industry, and the military. As battery technology becomes more complex and users' expectations become more pronounced, there is a pressing need for highly accurate assessment techniques that can give state-of-health readings in conditions approaching real time.

Transducer-Actuator Systems for On-Machine Measurements and Automatic Part Alignment

These systems have applications in machine shops, and in automotive and aircraft parts and manufacturing.

When performing machine tool setup and maintenance operations, it is frequently necessary to use a position transducer to “sweep” a surface and establish its relationship to a machine. A machine operator or maintenance technician typically attaches a position indicator to one portion of a machine, and then sweeps the position transducer over the object of interest, while observing the indicator run-out. If necessary, multiple adjustments and re-checks are made to the position of the object to obtain the desired alignment condition.

Paper-Based Electrochemical Test Strip Detects Harmful Bacteria

This test could eliminate the need for more expensive follow-up tests.

Borrowing concepts from medical diagnostic devices, researchers have created a simple, inexpensive set of handheld tests that can detect the presence of many water- or food-borne pathogens. If applied in the field, such tests could greatly reduce the number of expensive follow-up tests needed to keep the food supply safe from fecal contamination.

ASTM D4169: A Historical Perspective, plus Review and Implications of D4169-16

WESTPAK's protective package system testing professionals present a webinar focused on ASTM D4169. We begin with a historical perspective of D4169 and its origin to provide you with a background on protective package testing protocols. Then we review D4169-16 and compare it against the prior revisions. We discuss options available if your test fails the –16 revision after passing prior revisions. Live Q&A will be included during the broadcast.
