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 hand-held mobile communication device, such as smart telephone, incorporating sensors and signal conditioning modules for measuring signals from external sources of electromagnetic radiation (EMR) in the low, radio, ultraviolet, and infrared spectral ranges. These include the detector for receiving and monitoring electromagnetic fields originating from various external sources of radiation that pose potential health hazards or may interfere with various electronic devices. The mobile phone equipped with such sensors could alternate between communication and monitoring functions. Other integrated EMR sensors are a photodiode for the ultraviolet detection to monitor the user's sun exposure and a thermopile for non-contact measurement of temperature of humans or inanimate objects. This infrared sensor in combination with a photographic digital camera and a pattern recognition signal processing allows measuring temperatures at specific locations and from optimal distances to the surface of the object to enhance accuracy of non-contact temperature measurements.

Abstract:
A portable UV detection apparatus is disclosed. In one embodiment, the UV detection apparatus includes a UV detection device integrated with a skin type measuring device. A controller can be included in the apparatus that is in communication with the skin type measuring device and the UV detection device. The controller can provide information to the user regarding the amount of ultraviolet radiation present in the environment. In an alternative embodiment, the UV detection apparatus includes a UV detection device in conjunction with a light sensor. The light sensor can be configured to activate the UV detection device should light at a particular intensity be present in the environment. The UV detection device as described above can be configured to measure UVA radiation, UVB radiation, and/or UVC radiation.
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.
