We present a high-speed optical beamsteering system based on an 8x8 MEMS phased array. The system incorporates an in situ interferometer that provides a real-time, dynamic measure of the phase of each mirror in the array during beamsteering. A closed-loop phase-control algorithm results in <π/100 mirror phase accuracy and far field beam steering is shown. Stroboscopic measurement capabilities a...

Control over drop size distributions, injection rates, and geometrical distribution of fuel and oxidizer sprays in bi-propellant rocket engines has the potential to produce more efficient, more stable, less polluting rocket engines. This control also offers the potential of an engine that can be throttled, working efficiently over a wide range of output thrusts. Inkjet printing technologies, ME...

The apparent, perhaps as well as hidden, messages from our visits to cutting-edge academic MEMS research labs and leading-edge industries engaged in MEMS in Japan unequivocally created rapid flashbacks and reassuring reminders. We were pleased to see some of what we had heard about, what we had talked about, and what we had thought about in the United States, already being under development, wo...

FLEXIBLE MEMS DEVICES:A NOVEL TECHNOLOGY TO FABRICATE FLEXIBLE ELECTRONICSby

introduction: caring is the essence of nursing and medication process is an important part of nursing related interventions in the health care systems. medical and/or nursing errors can lead to severe problems for both patients and nursing system. the purpose of this study was to investigate the ethical practice in medication process among nurses working in selected hospitals related to tehran ...

Objectives The aims of the study were to investigate discrepancies between general practitioners' paper medication orders and pharmacy-prepared electronic medication administration charts, back-up paper charts and dose-administration aids, as well as delays between prescribing, charting and administration, at a 90-bed residential aged care facility that used a hybrid paper-electronic medication...

The American Society of Health-System Pharmacists (ASHP) believes that an effective process for medication reconciliation reduces medication errors and supports safe medication use by patients. ASHP encourages hospitals and health systems, including community-based providers and managed care systems, to collaborate in organized, multidisciplinary medication reconciliation programs to promote co...

A study about the piezoresistive Micro-Electro-Mechanical Systems (MEMS) cantilever for a chemical sensitive mass based sensor has been carried out to enhance sensor sensitivity. The sensitive region attracts the CO2 molecules there by introducing the stress concentration region (SCR). Three types of SCR geometry designs were first analysed using Intellisuite software to study the effect of str...
