    • An image sensor for capturing a color image is disclosed having a two-dimensional array having first and second groups of pixels wherein pixels from the first group of pixels have narrower spectral photoresponses than pixels from the second group of pixels and wherein the first group of pixels has individual pixels that have spectral photoresponses that correspond to a set of at least two colors. Further, the placement of the first and second groups of pixels defines a pattern that has a minimal repeating unit including at least twelve pixels. The minimal repeating unit has a plurality of cells wherein each cell has at least two pixels representing a specific color selected from the first group of pixels and a plurality of pixels selected from the second group of pixels arranged to permit the reproduction of a captured color image under different lighting conditions.

    • The present invention contributes to advancements in the art of inventory management and distribution by providing a system and method for processing, distributing, and tracking reusable inventory items. Reusable articles, such as surgical garments and accessories, are adapted with radio frequency identification (“RFID”) tags having unique identification numbers. A “reader” is used to retrieve stored information from the tags without requiring direct contact or clear line-of-sight. The reusable articles are processed and distributed using an inventory management system wherein lifecycle data is obtained for each reusable article. The reusable articles are distributed to the end users from central processing facilities, used, returned, cleaned, inspected, folded, sterilized, and returned to inventory for re-distribution. Periodic quality control inspections are conducted in response to predetermined usage parameters. The use of RFID tags and a corresponding computer network allows for the acquisition of data corresponding to each reusable article within a distribution system having multiple remote distribution and processing facilities. The acquired data is transmitted to a central computer processing system via a secured wide area computer network for use and analysis. Data processing computer servers at each remote distribution and processing facility electronically linked to a central data processing server provide a fail-safe network for acquired data.
    • 本发明通过提供用于处理,分发和跟踪可重复使用的库存物品的系统和方法,有助于库存管理和分配领域的进步。 诸如手术衣服和附件的可重复使用的物品适用于具有唯一识别号的射频识别(“RFID”)标签。 “读者”用于从标签中检索存储的信息,而不需要直接接触或清除视线。 使用库存管理系统处理和分发可重复使用的物品,其中为每个可重复使用的物品获得生命周期数据。 可重复使用的物品从中央处理设施分发给最终用户,使用,退回,清洗,检验,折叠,灭菌,并归还库存进行重新分配。 响应于预定的使用参数进行定期质量控制检查。 使用RFID标签和对应的计算机网络允许在具有多个远程分发和处理设施的分发系统内获取对应于每个可重复使用的物品的数据。 所获取的数据经由安全的广域计算机网络传送到中央计算机处理系统以供使用和分析。 电子链接到中央数据处理服务器的每个远程分发和处理设施的数据处理计算机服务器为采集的数据提供故障安全网络。

    • A multi spacing decking tool allows comprising an elongated planar body provided with a plurality of spacers which have V-shaped teeth allows the installer to achieve the even gaps between decking planks and boards by accommodating up to six decking boards at a time, cutting the time it takes to achieve the gaps between boards. The V-shaped teeth enable the gauge to smoothly slot in between each plank or board and will set the same even gap throughout the work surface. The multi spacing decking tool allows the installer to achieve a faster installation of the decking boards.
