Abstract: Sensorised wheel hub unit and a method for detecting, in real time, forces and moments applied to an outer ring of the wheel hub unit in which piezoresistive ceramic plates are made of one piece with welded metal plates housed within respective recesses formed in an outer surface of the outer ring over respective races for rolling elements that there is a gap between the plates and a base wall of each recess; the temperature of the outer ring and the amplitude and frequency of first electrical signals (S1) associated with the sensors relating to the same race are analysed to determine a frequency value equal to the frequency of the first signal having the maximum amplitude and as many amplitude values (D1-Dn) as there are sensors associated with that race and each equal to the maximum amplitude of the first signal from each sensor, corrected according to temperature.

Abstract: A sexual aid device includes a housing having a generally cylindrical base and central portion and an upper portion defining a closed upper end. The base includes an open lower end and at least the base and central portion are hollow. The housing is fabricated of a lubricious glass-based single piece of material. An electric motor is mounted in the hollow central portion of the housing and vibrator means including a block and an eccentric drive therefore is coupled to the motor. A battery means is disposed in the hollow base of the housing and is operably coupled with the motor. The motor and battery means are connected in series circuit and an end sealing means including a cap mounted on the open end of the base for releasably sealing the open end so that the hollow interior of the housing is waterproof when the cap is mounted on the base.
