A method for detecting the presence of humidity on a surface of a flat strip, in particular a bare metal strip or of a coated metal strip having the following steps: blowing on the surface an impinging air flow producing an air flow deflected by the surface, the impinging air flow not being saturated, measuring a humidity content of at least a portion of the deflected air flow, comparing the humidity content of the impinging air flow and the deflected air flow, if said humidity content of the deflected air flow is superior to the humidity content of the impinging air flow, the presence of humidity on the surface of the bare metal strip or of the coated metal strip is detected.

In one embodiment, a flexible composite conducting polymer film includes a composite conducting polymer including a conducting polymer and one or more water-soluble polyanions, wherein the film is approximately 20 nanometers to 10 microns thick.

A mobile apparatus that is automated to measure controlled and applied forces to sport surfaces allowing for safety assessment of athletic apparel and athletic surfaces, such as natural or artificial turf. The apparatus is capable of using not only horizontal and vertical forces, but also rotational moments, and all prescribed forces and moments in combination at the same or different times. The apparatus and related system can apply horizontal and vertical forces, and rotational moments, and link these forces and moments together and combine them to more closely mimic behavior of human foot during an athletic movement, thereby applying and measuring interactions between all forces and moments at the same or different times.

Methods, systems, and computer program products for determining a property of construction material. According to one aspect, a material property gauge operable to determine a property of construction material is disclosed. The gauge may include an electromagnetic sensor operable to measure a response of construction material to an electromagnetic field. Further, the electromagnetic sensor may be operable to produce a signal representing the measured response by the construction material to the electromagnetic field. An acoustic detector may be operable to detect a response of the construction material to the acoustical energy. Further, the acoustic detector may be operable to produce a signal representing the detected response by the construction material to the acoustical energy. A material property calculation function may be configured to calculate a property value associated with the construction material based upon the signals produced by the electromagnetic sensor and the acoustic detector.

A device is provided for determining material properties of a material, preferably a wood or a wooden material, having a pin arrangement having at least two pins, a drive unit for at least partially driving the pins into the material using a defined force, and a measuring unit for measuring both the penetration depth of at least one of the at least two pins and also an electrical resistance between two of the pins.

A device for monitoring humidity in a compressed air system comprises a light emitter; a light sensor; and a hygromorphic element. The hygromorphic element is exposed to a source of compressed air and positioned between the light emitter and the light sensor. The hygromorphic element changes the amount of light passing between the light emitter and the light sensor as the humidity in the compressed air increases.

A method for injecting data into a secure distributed computing system includes obtaining characteristics of an object via a secure operable connection from a smart silo. The method further includes verifying an identity of the smart silo based on credentials included in a message from the smart silo received via the secure operable connection. The methods further includes making a determination that the characteristics match a trigger condition of a smart contract. The method further includes executing the smart contract in response to the determination.
