Abstract: A weight measuring device includes a first link coupled to one end of a load to be measured. A second link is coupled to another end of a load to be measured. The first and second links include respective sections of a housing configured to place a spring in increasing compression with respect to increasing load on the first and second links. A hall cell and magnet are coupled between the first and second links to enable relative movement therebetween. The hall cell generates a signal related to an amount of movement of the first link with respect to the second link.

Abstract: A turbine operated electric generator includes a turbine and a magnetic gear unit rotationally coupled at an input thereof to at least one of an inner rim of the turbine and an outer rim of the turbine. An output of the magnetic gear unit is configured to operate an electric generator. The magnetic gear unit includes magnets configured to at least one of increase a rotation speed at the output with respect to the input speed and inversely change a torque at the output with respect to the input and decrease the output speed with respect to the input speed and inversely change the torque.
