Electrochromic + Anti-Fog Personal-Protective Eyewear (PPE) Based on Unique, Very Low Power, Conductive Coatings and Leveraging Unique, ANSI Z87.1-/Military-Qualified Electrochromic Eyewear Technology

关于个人防护眼镜(PPE)技术，高风险的主要职业危害 工业部门，如制造、采矿、建筑、仓储、环境修复/- 清理和生物医学清理(例如在埃博拉工作中)，但到目前为止受到的关注非常有限， 这是否与工人从非常明亮的区域过渡到黑暗区域有关；个人防护装备的雾化 加剧了这种情况。根据OSHA最近的统计数据，可能由以下原因导致的致命事故数量 明/暗(L/D)加上雾化问题可能占总数的35%(2012年为4,383人，3.2/100,000人)， 具有类似比例的非致命事故。在生物危害工作中，穿西装的人迫切需要自动化， 免提L/D加上防雾控制。目前用于L/D控制的个人防护技术(如光致变色 用紫外线改变颜色，在室内或汽车内不起作用)，夹式太阳镜或额外的太阳镜，以及 防雾剂(如超亲水涂料或双嵌段聚碳酸酯)都严重不足。的确， 美国陆军公共卫生司令部明确禁止军事人员使用光致变色剂或夹子。 现在，在最近的先前和正在进行的工作中，这家公司已经开发出一种新的电致变色材料并获得了专利 基于独特的匹配双聚合物导电聚合物电致变色技术 具有小的，例如5VDC的电压)；这具有极好的性能，克服了阻碍实用的缺点， 到目前为止，商用电致变色眼镜。典型表现：L/D对比1%至70%(与AIR 参考)；薄(&lt；0.4 mm)、灵活、耐用的结构；独一无二的施加电压算法 价格低廉(8美元)的微控制器，开关时间为&lt；2 S LD，~瞬时DL；自动- 功能(基于光电传感器，可充电锂电池供电)；非常低的功率(72小时，12个L/D/L开关 电池需要充电前的每小时；15微瓦/平方厘米，+/-3.0 VDC)；符合ANSI Z87.1-2010和美国 军用(阿佩尔)规格。此外，这家公司还开发了一种独特的、主动的除雾 技术在第一阶段的工作中，这两种技术(电致变色+除雾)结合在一起， 眼镜/护目镜具有良好的电致变色性能，主动除雾。 秒，而且耗电量非常低。初步完成了最终成型眼镜的CAD设计。 拟议的第二阶段工作将：(1)进一步优化这些眼镜/护目镜的性能，包括控制， 功耗高，除雾性能好。(2)用全身生物医疗服展示其功能。(3) 设计并建立一条半自动、中试生产线，每月生产100副眼镜/护目镜，利用 该公司刚刚开始商业化生产其标准(不是除雾)电致变色太阳镜。(4) 与确定的合作伙伴建立商业化合作关系。如果成功，价格低廉(80美元)的产品 这项工作的结果将是第一个商业上可行的电致变色+除雾眼镜，彻底地 升级个人防护装备。辅助市场(滑雪服、赛车、自行车、足球、军事)可能会进一步降低成本。

With regard to Personal Protective Eyewear (PPE) technologies, a major occupational hazard in high risk industrial sectors such as manufacturing, mining, construction, warehousing, environmental remediation/- cleanup and biomedical cleanup (e.g. in Ebola work), but one which has received very limited attention to date, is that associated with the worker transitioning from very bright to dark areas; fogging of the PPE exacerbates the situation. Per recent OSHA statistics, the number of fatal accidents potentially caused by light/dark (L/D) plus fogging issues may be up to 35% of the total (4,383 in 2012, 3.2/100,000 workers), with non-fatal accidents having a similar proportion. In biohazard work, the suit wearer critically needs automated, hands-free L/D plus antifogging control. Current PPE technologies for L/D control (e.g. photochromics changing color with UV light, not working indoors or in cars), clip-on sunshades or extra sunglasses, and for antifogging (e.g. superhydrophilic coatings or double-pane polycarbonate), are all grossly inadequate. Indeed, the US Army Public Health Command specifically prohibits photochromics or clip-ons for military personnel. Now in very recent prior and ongoing work, this firm has developed and patented a new electrochromics technology, based on unique, matched-dual-polymer Conducting Polymer electrochromics (which change color with small, e.g. 5 VDC, voltage); this has excellent performance, overcoming drawbacks preventing practical, commercial electrochromic eyewear heretofore. Typical performance: L/D contrast 1% to 70% (vs. air reference); thin (< 0.4 mm), flexible, durable construction; unique applied-voltage algorithm residing on an inexpensive (<$8) Microcontroller yielding switching times of < 2 s LD, ~instantaneous DL; automated- function (photosensor-based, rechargeable Li battery-powered); very low power (72 h with 12 L/D/L switches per h before batteries need recharging; 15 µW/cm2, +/- 3.0 VDC); conforming to ANSI Z87.1-2010 and US military (APEL) specifications. Furthermore, this firm has also developed a unique, active defogging technology. In the Phase I work, these two technologies (electrochromics + defogging) were combined, with spectacles/-goggles demonstrated having excellent electrochromic performance, active defogging in < 4 seconds, and very low power consumption. A preliminary CAD design for final-form eyewear was arrived at. Proposed Phase II work will: (1) Further optimize performance of these spectacles/goggles, including control, power consumption, defog performance. (2) Demonstrate their function with full-body biomedical suits. (3) Design and set up a semi-automated, pilot production line for 100 spectacles/-goggles per month, leveraging the firm’s just-initiated commercial production of its standard (not defogging) electrochromic sunglasses. (4) Establish commercialization tie-ups with partners identified. If successful, the inexpensive (<$80) product resulting from this work will be the first commercially viable electrochromics + defogging eyewear, drastically upgrading PPE. Ancillary markets (skiwear, motor sports, bicycling, football, military) may further lower cost.
