Preferably, a multitude of emission members (E) for emitting light generally detectable by said detecting members (D) is arranged on said substrate wafer (PW) such that a multitude of neighboring emission members and detecting members are present on said substrate wafer. Single modules (1) can be obtained by separating said wafer stack (2) into a multitude of separate modules (1).
Abstract:
Embodiments provide a handheld optical measuring device and method of measuring an optical property of a liquid sample. In some embodiments the optical measuring device includes a handheld controller module having an immersible sensor head and a sampling member including a sample cup and an attachment member that couples the sample cup to the handheld controller module. In some embodiments the attachment member is an elongated rigid member that is hingedly coupled to the controller module, thus providing a folding configuration for enclosing the sensor head with the sample cup during measurements, transportation, and/or storage. In some embodiments the attached sample cup provides a protective shell for the immersible sensor head during use and/or when not in use.
Abstract:
A method for providing an intensity or brightness measurement using a digital image-capturing device comprising: selecting a target area within a field of view of the image-capturing device, the target area containing pixels; measuring the intensity or brightness of pixels in a target area; accumulating the intensity or brightness values of the pixels in the target area; and determining a pixel value representative of the intensity or brightness of the pixels in the target area. A device for making color measurements comprising an image-capture device, a processor or logic device, and a memory location for accumulating color data, and the processor or logic device is programmed to perform color measurements by accumulating the data for pixels located in the target area in memory, and determining a representative color value.
Abstract:
A system configured to monitor ambient illumination experienced by a subject. In one embodiment, the system comprises an illumination sensor, a timer, and a storage module. The illumination sensor is configured to monitor an intensity of ambient illumination within two or more wavelength ranges by generating one or more output signals that convey information related to the intensity of ambient illumination within the two or more wavelength ranges. The timer is configured to indicate the passage of periods of time. The storage module is configured to store information related to the intensity of ambient illumination within the two or more wavelength ranges, as conveyed by the one or more output signals, for individual periods of time. The system is portable to be carried by the subject.

Abstract:
Embodiments provide an optical sensor head and method of making an optical sensor head. In some cases the sensor head can be used as a fluorometric sensor to measure concentrations of substances within a liquid sample of interest. The sensor head includes a light source window and a detector window that transmit light between the sensor head and an analytical area. In some cases the windows include a ball lens positioned within a channel such that the ball lens and the channel create a seal between the interior and exterior of the sensor head.
Abstract:
A hand-held mobile communication device 1, such as smart telephone, incorporating sensors and signal conditioning modules for measuring signals from external sources of electromagnetic radiation (EMR) in different spectral ranges. These include a detector 30 monitoring EMR that pose potential health hazards or may interfere with various electronic devices. Other integrated EMR sensor is a photodiode 16 for the ultraviolet detection to monitor the users sun exposure and a thermal infrared detector 15 for non-contact measurement of temperature of humans or inanimate objects. This detector in combination with a digital camera 16 and pattern recognition signal processing allows accurate non-contact measuring temperatures at specific location.
