Purdue University researchers have devised miniature transducers that are implanted in tumors to generate oxygen, boosting the killing power of radiation and chemotherapy.
The options when specifying sensors for long-range object detection or positioning usually boil down to two alternatives: optical sensors using either infrared or visible-red light and ultrasonic. Optical sensing is often the first choice
The EGT Diesel & Biofuel Exhaust Gas temperature sensor from The Sensor Connection, Troy, Mich., features a noncorrosive sensing tip that withstands sulfuric exhaust gases from burning biofuels and diesel fuels
Engineers at Libelium, a firm based in Spain, have developed a network of radiation detectors that are being deployed around Japan’s troubled nuclear reactors. Dozens of the battery-powered devices will sit atop streetlights
The industrial fixed-mount ID readers from Cognex Corp., Natick, Mass., use a liquid lens to focus the device’s sensor on a bar code or other printed ID. The lenses use no moving parts
The market’s smallest three-channel reflective encoder, the new line of AEDR-850× encoders from Avago, San Jose, feature an LED light source, photodetecting and interpolator circuitry, and three channels in a 3.95 × 3.40-mm leadless package
Tracking gaps in a laser-drawn line of light measures the position errors between two separate parts. Robots can then mount the two parts flush with equal spacing all around
