An ambient light detection unit for a household appliance includes a sensor housing and a brightness sensor which is disposed in the sensor housing and detects the brightness of the ambient light in the environment. The ambient light detection unit has a lens with which the ambient light that is incident on the sensor housing is focused toward the brightness sensor. A household appliance is also provided.

An apparatus may include a sensor housing, a light sensor disposed within the sensor housing, the light sensor arranged to generate a detection signal when light impinges on the light sensor, a sensor lens disposed at least partially outside the sensor housing, wherein a distal portion of the sensor lens extends a first distance above the sensor housing, the sensor lens being transparent, wherein light received from outside the sensor housing is transmitted to the light sensor; and a light emitter assembly disposed outside the sensor housing at a second distance above the housing less than the first distance.

There are many manufactures, makes, and models of solar radiometers to choose from. There are also many radiometer housings to choose from. I have not observed or deployed any of the combinations available for solar radiometers to satisfy the requirements of unattended perfect solar radiation measurements in cold climates. There is a large expense involved with deploying radiometers in remote Arctic and Alpine regions. Huge expense is continually lost due to the lack of consistent quality data. My concept has continually proven and guarantees that time and money will not be lost. This was proven with an intensive parametric comparison study that by focusing a volume of air with the proper amount of force, specifically with the Albee Arctic Kick-ice System Radiometer Housing (Patent pending #61/934,754, Patent pending #62/107,441), is completely effective in combating all icing issues using a variety of radiometers from quality radiometer manufacturers. Being able to deploy solar radiation instruments in harsh environments with confidence will save huge amounts of money and bring solar radiation science to a higher level of success.

A visible LED light scattering apparatus comprising a substantially hollow spherical cavity including a light entry port arranged to receive visible light from an LED mounted outside the cavity, a light exit port located opposite the entry port and through which the LED light exits the cavity for analysis, and a baffle located in a central region of the cavity in a direct optical path between the entry port and the exit port to interrupt the passage of visible LED light between the entry and exit ports.

A method includes sensing data indicative of a plurality of wavelengths of light utilizing one or more sensors forming a part of a sensor ring, storing the data on a memory device forming a part of the sensor ring, transmitting the data to a computing device external to the ring and receiving a photic environmental model from the computing device the photic environmental model based, at least in part, on the data.

A solar radiation protective band for a driver that includes a housing and an armband. The housing includes a front panel, a side panel, and a microcontroller. The front panel includes a front panel UV light sensor, a front panel IR phototransistor, and an LCD. The side panel includes a side panel UV light sensor, and a side panel IR phototransistor. A temperature sensor measures a skin temperature and generates a temperature signal. A skin color sensor detects a skin color of the driver and generates a skin color signal. The microcontroller requests an input of a SPF of a sunscreen used by the driver; calculates an exposure time threshold; generates a UV exposure warning when an exposure time exceeds the exposure time threshold; calculates an updated skin temperature; and generates an IR exposure warning when the updated skin temperature exceeds a maximum skin temperature threshold.
