Abstract: The present invention discloses a design for a measurement device with improved power measurement accuracy, involving the measurement of the temperature using a highly accurate device that can be installed coupled to the protectors, the device comprising: an essentially rectangular parallelepiped-shaped casing with a plurality of slots in the lateral surfaces, one or more openings, and at least one electrical connection rod; a motherboard (PCB) on the inside of the casing, comprising a first face having at least one Shunt resistor and its own power supply, and a second face, opposite the first face, having—a communication module consisting of a microcontroller that is connected to the measurement module, —a temperature sensor disposed on the second face (PCB) and on the side opposite the Shunt resistor, and—electrically isolated communication ports; and an analogue-to-digital converter.

Abstract: The present disclosure describes a device formed by a substantially cylindrical, permeable sheath with a filling of biochar particles, which ensures the deep infiltration of rainwater, irrigation water or run-off, thereby preventing it from evaporating and optimising the use thereof. The disclosure also describes a method for increasing a crop yield by using the disclosed devices.

Abstract: A water craft constituted by a fiberglass body with a streamlined bow in back of which is a recess forming a seating compartment. The rear end of the body is formed to provide a keel. Front-to-back guides in the seating compartment support a shiftable seat having dismountable arms that extend laterally to opposite sides of the body to support floats at their ends. In front of the seat, pedals are supplied which are kinematically joined to a central shaft within the body that is connected to a drive shaft that emerges from the body for driving a propeller.
