Force Sensing System for Surgical Self-Retaining Retractors
This invention is a single self-retaining retractor with an autoclave force sensor mounted on each side of the retractor at the tissue interface. A force sensor is connected to a processing circuit via autoclave wires and a thermocouple. The processing circuit is connected via a Bluetooth low energy (BLE) with a mobile application to display store and...

All-Fiber Multicore Fiber Laser Devices
Researchers at the University of Arizona have developed a compact, power-scalable, alignment-free fiber laser that takes a new approach to stabilizing phase-locked operation of multi-core fiber lasers by completely removing all free space optical components. This high-brightness, all-fiber laser package uses passive optical fiber spliced at both ends...
