Precision Detector Conductance Definition via Ballistic Thermal Transport

This innovation could be applied in the development of bolometric detector array sensors. Goddard Space Flight Center, Greenbelt, Maryland The characteristics of a thermal detector, such as sensitivity, response time, and saturation power (or energy resolution), are functions of the thermal conductance of the detector to its cryogenic environment. The thermal conductance is specified to achieve a tradeoff among the highest sensitivity, allowed response time, and the desired saturation energy or power budget for the particular application. It is essential to achieve the design thermal conductance (within an acceptable variance) after a thermal detector has been fabricated. Otherwise, the detector will fail to achieve its desired functionality. In addition, the formation of a multi-pixel imaging array becomes difficult and costly when the design thermal conductance is not achieved with high post-fabrication yield.

DryLin® E7 plastic linear plain bearings versus PTFE-lined plain bearings

Linear plain bearings are becoming commonplace in today’s manufacturing industry. As technologies and material sciences have advanced, so have the capabilities of linear plain bearings, particularly those made of plastic, such as the DryLin® series of self-lubricating linear bearings from igus®. This whitepaper will compare how they outperform a competitive linear plain bearing technology, which uses a PTFE-based, bonded liner, in both wear and friction testing.

Mini Force Fields Control Individual Microbots

Researchers are using a technology likened to "mini force fields" to independently control individual microrobots operating within groups, an advance aimed at using the tiny machines in areas including manufacturing and medicine. Until now it was only possible to control groups of microbots to move generally in unison.
