  • Patent number: 10305067
    Abstract: The invention relates to a substrate (2) for manufacturing an organic conversion device for converting electrical energy into light energy or light energy into electrical energy, wherein the substrate comprises a) an encapsulation layer (3) on the substrate, wherein the encapsulation layer includes a first inorganic layer (7), a second inorganic layer (9) and an intermediate organic layer (8), and b) a getter reservoir (6) in contact with the organic layer of the encapsulation layer. Water molecules will therefore not only be transported along the intermediate organic layer, but will also be gathered, especially absorbed, by the getter reservoir, if the encapsulation is damaged. This can slow down a transport of water molecules along a leakage path towards an organic conversion layer of the organic conversion device and hence slow down a possible degradation of the performance of the organic conversion device, if the encapsulation layer is damaged.

  • Patent number: 9632070
    Abstract: A method where the weight of the bale is measured by a scale on the baler, the moisture of the bale is measured by sensors on the baler and this information is sent to a processor. Based on compaction properties of the leaf verses the stem of the alfalfa, the processor calculates a feeding value for the hay including protein, energy and relative feed value on the dry density of the bale. Additional inputs such as the compaction setting of the baler and information about the hay being harvested can also be input into the processor for making adjustment to the feeding value calculation.

  • Patent number: 9568445
    Abstract: A salt-based device and a circuit to monitor and log the time periods a data center air's relative humidity goes above a predefined limit. The choice of the salt is such that its deliquescent relative humidity is equal to the desired limit, so that above the desired limit, the salt gets wet and therefore electrically conductive. An alarm can then give notice that relative humidity levels are above acceptable levels so that remedial action may be taken before problems such as electronic malfunction develop.
