Abstract: A multi-spectral photodetector is provided, comprising: a plurality of N photodetectors where N is an integer such that N?2, each photodetector comprising an anode and a cathode separated from one another by a region of interest, all produced in a semiconductor material; at least one electrical contact for all of the N anodes; and an electrical contact associated with each of the N cathodes; said photodetectors being stacked on top of one another such that the anodes and the cathodes and finally the regions of interest of two consecutive photodetectors in the stack are arranged face to face, this stack making it possible to define a face, termed the active face of the multi-spectral photodetector, common to all the photodetectors of the stack, defined by the face of the first region of interest of the first photodetector of the stack via which photons are intended to enter the stack.

Abstract: The invention relates to a portable and ergonomic instrument for storing golf balls and tees and for automatically positioning a tee in the ground at a predetermined height and a ball in balance thereon, by means of a movement of one hand on the part of the player in the standing position. Said instrument consists primarily of a main body (10) serving as a storage unit (12) for balls (Bn), a multi-purpose shuttle (20) and a retaining clamp (P). After setting the desired height of the ball on the thumbwheel (50), the alternating movement of the shuttle (20) from abutment to abutment, using the knob (21), first upward, then downward and finally upward, enables the result to be achieved. Any golfer who has difficulty bending down or squatting, and those who do not wish to bend down or squat, may be interested in owning such an instrument.

Abstract: A semiconductor substrate (100) has three doped zones (1), (2) and (3), forming a P-N junction (101), the third zone being located between the first zone and the second zone. The P-N junction of the substrate further has a fourth doped zone (4) having a first portion (4A) in contact with the first zone; and a second portion (4B) in contact with the third zone (3), said second portion (4B) extending in the direction of the second zone (2), and not being in contact with the second zone (2); where the fourth zone (4) being doped with the same type of doping as that of the first zone.

Abstract: A novel compound which can be used in the field of separation and purification of gases is disclosed. The compound can be incorporated into a silica gel incorporating polyazacycloalkane structural units for separating a predetermined gas from a mixture of gases. The mixture of gases is brought into contact with a metallated hybrid gel under conditions which make possible the absorption of the gas to be separated, followed by a phase of desorption of the attached gas, and the recovery of the gas.

Abstract: A tire for two-wheel vehicle comprising a casing formed of a crown with a tread and two sidewalls each terminating in a bead intended to rest on a tire rim and an inner tube glued in manually removable manner to the inner wall of the casing in the region of the crown is improved due to the fact that the inner tube is glued under circumferential tension to the casing so that its inside equatorial radius is greater than the outside radius of the flanges of the rim. The adhesive used may have self-sealing properties.
