Abstract: The present invention relates to a biodegradable thermoplastic elastomer having the general formula A-B-A wherein each A is an amorphous polymer having a glass transition temperature (Tg)>40° C. or a semi-crystalline polymer having a glass transition temperature (Tg) and/or melting temperature (Tm)>40° C.; B is a copolymer of -caprolactone (CL) and at least one additional monomer selected from the group consisting of L-lactic acid (LLA), trimethyl carbonate (TMC), and glycolic acid (GA), or B is different to A and is lactic-co-glycolic acid (LGA); and wherein the molar ratio of CL to the at least one additional monomer in the copolymer B is in the range between about 1:0.09 to about 1:1.

Abstract: The present invention relates to a device for detecting the opening of a hatch closing a case in an item of equipment including one or more electronic circuit boards, the planes of which are substantially orthogonal to the plane formed by the said hatch, at least one of the said boards including at least two conductive parts electrically insulated from one another and each connected to a detection circuit, a conductive element being attached to the inner side of the hatch, a portion of each of the conductive parts extending laterally to the side of the edge of the said electronic circuit board which is proximal to the hatch, the said conductive element being placed facing the said conductive parts so as to come into contact with them when the hatch is placed in the closed position.
