Abstract: The present invention provides a portable golf club head cleaning device designed to more conveniently and effectively clean golf club heads and comprising a housing with a top surface defining an enclosed club entrance aperture, a liquid storage cavity defined within the housing and operably configured to house a liquid therein, at least one cleaning brush with a central core, an upper brush end 140, a lower brush end 142, a plurality of bristles disposed along the brush length and extending radially outward from the central core and operably configured to rotate 360°, and at least one DC motor electrically coupled to a battery-powered power source and an electronic switch operably configured to selectively complete a circuit with the battery-powered power source and the at least one DC motor and cause rotation of the at least one cleaning brush about a central core axis.

Abstract: A virtual heat metering system (10), includes sensors (12, 14, 16, 18, 20), adapted to be associated with a supply circuit of a central thermal installation (I) and arranged for supplying main signals (Qman., Tman., Trit., Pman., Prit., s) indicative of physical quantities representing the operation of the supply circuit (C) in a predetermined period of time (?tTOT). A control apparatus (22), includes a memory module (23) arranged for storing a thermal and fluid dynamic model (M) defined initially and representing the central thermal installation (I), identified on the basis of physical quantities representing the operation of the supply circuit (C) and the heat exchanger devices (H1,1, . . . , H1,n1; H2,1, . . . , H2,n2; . . . ; Hm,1, . . . , Hm,nm), detected in specified conditions of operation and stimulation of the installation (I); and data representing the variation of said main signals (Qman., Tman., Trit., Pman., Prit., s) in the period of time (?TOT).

Abstract: Pressure sensors situated on opposite sides of a land motor vehicle relative to the direction of travel enable a signal to be generated which is indicative of the presence and the direction of a gust of cross-wind striking the vehicle. Flaps, which are connected to the sensors and are normally closed flush with the body, are movable to project selectively from the outer surface of the motor vehicle, in the event of a gust, to induce in the vehicle a slewing moment in the direction opposite the direction of the gust.

Abstract: Air intakes, usually constituted by N.A.C.A. intakes, are formed in the sides of the motor vehicle immediately in front of each rear light unit. When the vehicle is moving, each of the intakes induces a flow of air towards the light unit. As it passes through flow-conditioning means, such as a deflector element mounted in a corner position on the light unit or a slot-like duct which passes through the light unit, this flow is transformed into a turbulent air flow. As it spreads into the space surrounding the surface of the light unit and/or flows over it, this air flow prevents the deposition of dirt on the light unit.
