Abstract: Systems, methods, and software for providing digital security to a child message transmitted from a mobile device to a messaging server, where the mobile device typically does not transmit the parent message with the child message to the messaging server. Whether to apply digital security, such as encryption or a digital signature, or both, is determined, and if the mobile device does not include a complete copy of a parent message for insertion into the child message, the mobile device selectively downloads the parent message from the messaging server prior to the computation of a digital signature or prior to encryption. The systems and methods may also provide a check of the child message size, when the child message includes inserted parent content, to ensure that the child message does not exceed any prescribed limits on message size.

Abstract: L'invention concerne un ensemble d'ancrage de roche (1) qui comprend un goujon d'ancrage (2), et elle concerne en particulier un goujon (1) expansible à tube de frottement qui est placé par une douille d'extrémité (4) dans un trou foré préalablement, un adaptateur (6) doté d'une amenée et d'une évacuation de liquide étant ensuite placé sur une douille (3). D'une part, on crée par un conduit (8) à fluide sous pression une pression de maintien qui immobilise l'adaptateur (6) sur la douille (3). D'autre part, du fluide pénètre dans le goujon d'ancrage (2) par un conduit de dilatation (7) et commence à remplir ce goujon. Du fait de l'augmentation de pression (pression du gonflement), le goujon d'ancrage (2) se dilate dans le trou foré de telle sorte que sa surface extérieure vient se placer contre la paroi du trou foré et immobilise ainsi l'ensemble d'ancrage de roche (1) dans le trou foré. Avant et/ou après la dilatation du goujon d'ancrage (2), un gaz sous pression, en particulier de l'air sous pression, peut être injecté dans le goujon d'ancrage (2) par une amenée de gaz reliée à l'adaptateur (6). Le gaz comprimé se détend après démontage de l'adaptateur (6) (équilibrage de pression) et expulse presque complètement le fluide présent dans le goujon d'ancrage (2) hors de l'ensemble d'ancrage (1).
