, 2011 القياس عن بعد هي تقنية تسمح بقياس البيانات ومراقبتها عن بُعد. يشير عادة إلى اتجاه واحد للمعلومات، أي من المستشعر إلى نظام الاستجواب أو نظام مسجل البيانات. يمكن تعريف القياس عن بعد على أنه فئة فرعية من الاتصالات، وهي طريقة أكثر تعقيدًا لتبادل المعلومات مثل الإنترنت أو المكالمات الهاتفية أو نقل الفيديو.

Arthritis Care &Research, Accepted Article.Purpose The study aimed to identify symptom‐based predictors of dry eye disease (DED) signs in the Sjögrens International Collaborative Clinical Alliance (SICCA) cohort. Methods Retrospective analysis examining 16 ocular symptoms (most graded 0‐4) and artificial tear (AT) use (graded 0‐3) as predictors of DED signs [abnormal ocular surface staining ...

Modulated-splitting-ratio fiber-optic temperature sensor [PDF]
A fiber-optic temperature sensor is described, which uses a small silicon beamsplitter whose splitting ratio varies as a function of temperature. A four-beam technique is used to measure the sensor's temperature-indicating splitting ratio.

Closed loop fiber optic rotation sensor [PDF]
, 1987 An improved optical gyroscope is provided, of the type that passes two light components in opposite directions through an optic fiber coil, and which adds a small variable frequency to one of the light components to cancel the phase shift due to rotation

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials
Advanced Engineering Materials, EarlyView.Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

Fiber-optic temperature sensor using a spectrum-modulating semiconductor etalon [PDF]
Described is a fiber-optic temperature sensor that uses a spectrum modulating SiC etalon. The spectral output of this type of sensor may be analyzed to obtain a temperature measurement which is largely independent of the transmission properties of the ...

In-Vivo Evaluation of a Fiber-Optic Splanchnic Photoplethysmographic Sensor during Open Laparotomy [PDF]
, 2009 There is a need for a reliable and continuous monitoring of abdominal organ oxygen saturation (SpO2). Splanchnic ischemia may ultimately lead to cellular hypoxia and necrosis and may well contribute to the development of multiple organ failures and ...

Advanced Engineering Materials, EarlyView.This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...
