Abstract: The present invention concerns fluorescent boron thienyldipyrromethene type compounds, their preparation process, as well as their use as an electron donor in the field of organic electronics, in particular for the production of a photoactive layer in photovoltaic cells of the bulk heterojunction type or for the production of field effect transistors.

Abstract: A roping harness is composed of a belt and a supporting seat joined to one another by joining straps, and comprising an attachment device. The seat is provided with means for adjusting the width to suit the user's morphology.

Abstract: An automatic dispenser of ground coffee having: a reservoir having a flow outlet opening and adapted to contain a quantity of ground coffee; at least one paddle mounted to rotate in the bottom of the reservoir to transfer a predetermined quantity of ground coffee from the reservoir through the flow outlet opening; and a motor assembly connected for driving the paddle in rotation. The motor assembly is composed of: a motor having two input terminals via which operating current is supplied to the motor; and a control circuit having at least one component connected to establish a short circuit between the two terminals after the supply of operating current to the motor has been cut off.

Abstract: A method is provided for the electrical protection of an electrical household appliance that is used to prepare food. The appliance includes an electric pump which is supplied with alternating current in order to convey a liquid through a conduit, and a heating element to raise the temperature of the liquid. The instantaneous value of the current I supplied to the pump is measured at regular time intervals. The method includes calculating the average value ?n of m current I measurements taken over a pre-determined time period T; comparing the average value ?n with a reference value ?ref calculated as the average value of the current I measurements taken over an earlier period of the same length; and opening the pump's power supply circuit when the difference between the average values ?ref and ?n exceeds a pre-determined threshold value ?1 for at least two successive time periods T as a result of low average current indicative of dry running.
