Abstract: A steam hairdressing apparatus to style the hair, including: a first and a second jaw arranged facing one another, a first treatment surface borne by the first jaw and a second treatment surface borne by the second jaw, the surfaces intended to grasp a lock of hair, a reservoir of liquid, a means of vaporization of the liquid in fluid communication with the reservoir, a steam distribution means in communication with the means of vaporization, comprising one or more steam distribution orifices in the direction of a lock of hair, the means of vaporization comprising a first vaporization chamber forming a unique volume, a second vaporization chamber equipped with a plurality of baffles, said chambers in fluid communication, the internal volume (V1) of the first chamber being greater than the internal volume (V2) of the second chamber.

Abstract: The invention relates to a weight sensor comprising strain gauges which are deposited in thick films on a support (2). The support is made from an electrically-insulating material which is intended to be applied to a metallic body (1) that is essentially subject to bending. According to the invention, the support (2) comprises a ceramic material which has a Young's modulus E2 that is equal to or less than that E1 of the biased metallic body (1) and which is applied to the latter by means of gluing.

Abstract: The invention relates to a weighing device comprising a rigid platform (10) which is intended to receive the weight to be measured, a fixed support area (20) and at least one weight sensor (30). One of the ends (60) of said sensor is embedded in the platform (10) while the opposite end (70) thereof is embedded in the fixed support area (20). The weight sensor (30) supports strain gauges (R1, Ri) and comprises a bar that can be deformed, mainly by means of flexion (40) under the effect of the weight applied to said platform. According to the invention, at least one of the embedded ends (60) of the weight sensor (30) is provided with a surface (S) that is intended to be directly fixed by means of adhesion to the rigid platform (10) or to the fixed support area (20).

Abstract: A force-measuring apparatus is provided having a first plate, a second plate disposed above the first plate and spaced apart from the first plate, an optical sensor having at least one optical fiber disposed between the first plate and the second plate, and a clamp for moving the first plate and the second plate together to compress the optical fiber, thereby applying a prestressing force to the fiber to reduce eccentricity effects.
