    • A heat exchanger evaluation system (84) includes a refrigeration subsystem (126) and a platform (94) in communication with the subsystem (126) for attachment of a heat exchanger (32). The system (84) further includes a thermal imaging camera (168) and a monitor (100). A method (180) entails routing a fluid (38) through the heat exchanger (32) via the refrigeration subsystem (126). The camera (168) detects the temperature variation across the heat exchanger (32) as the fluid (38) flows through the heat exchanger, and provides successive thermal images representing the temperature variation responsive to the flow of the fluid (38). The thermal images are utilized to determine an efficacy of the flow through the heat exchanger (32). In particular, a determination can be made as to whether the flow deviates from a pre-determined flow path (79) of the fluid (38) through the heat exchanger.
    • 热交换器评估系统(84)包括与用于附接热交换器(32)的子系统(126)连通的制冷子系统(126)和平台(94)。 系统(84)还包括热成像相机(168)和监视器(100)。 方法(180)需要经由制冷子系统(126)将流体(38)路由穿过热交换器(32)。 当流体(38)流过热交换器时,照相机(168)检测穿过热交换器(32)的温度变化,并响应于流体(38)的流动提供代表温度变化的连续热图像。 热图像用于确定通过热交换器(32)的流动的功效。 特别地,可以确定流体是否偏离流体(38)的预定流动路径(79)通过热交换器。

    • A series of optical spectral sensors is based on a combination of solid-state sources (illumination) and detectors housed within an integrated package that includes the interfacing optics and acquisition and processing electronics. The focus is on low cost and the fabrication of the sensor is based on techniques that favor mass production. Materials and components are selected to support low-cost, high volume manufacturing of the sensors. Spectral selectivity is provided by the solid-state source(s) thereby eliminating the need for expensive spectral selection components. The spectral response covers the range from the visible (400 nm) to the mid-infrared (25,000 nm/25.0 μm), as defined by the availability of suitable low-cost solid-state source devices. A refractive optical system is employed, primarily in an internal reflection mode, allowing a selection of sample handling tools, including, but not restricted to internal reflectance and transmittance. A secondary channel allowing for light scattering or fluorescence methods is an option. The targeted applications of the sensing devices are for lubricants and functional fluids in the heavy equipment, automotive and transportation industries. A source reference channel is included to provide measurement stability and temperature compensation.

    • An integrated spectral sensing engine is based on a combination of energy sources (illumination) and detectors housed within an integrated package that includes the sample interfacing optics and acquisition and processing electronics. The focus is on a miniaturized sensor system that can be optimized for specific measurements and can be integrated into a manifold-based sample handling system. Design and fabrication components are selected to support high volume manufacturing of the sensors. Spectral selectivity is provided by either continuous variable optical filters or fabricated filter matrix components. The spectral response of the primary sensors covers the range from the visible (400 nm) to the near-infrared (1100 nm), as defined by the availability of suitable low-cost solid-state detector devices. Provision is made to extend the range into longer wavelengths, and to shorter wavelengths for filter-matrix devices. A broad selection of measurement modes is defined and these include transmittance/absorbance, turbidity (light scattering) and fluorescence. On board data processing not only provides the primary data acquisition, as well as data massaging and the display and output of computed results. The targeted application of the spectral sensing devices are for water, pulp and paper, chemical and petroleum based industries. Alternative packaging regimes and the production of lower cost sensing devices can lead to the use of the spectral sensing devices in the medical, clinical, forensic and consumer based areas of application.
