  • Patent number: 11741198
    Abstract: The present invention relates to a system for rendering a content, the rendering of which is subject to conditional access security conditions. A system is described, comprising a host device and a detachable security device, the security device configured to decrypt the encrypted content, re-encrypt it under a local key and to deliver the re-encrypted content to the host device while ensuring that the host device applies or otherwise enforces any conditions associated with the rendering of the content.
    Type: Grant

  • Patent number: 9894851
    Abstract: A piece insertion method for a pipe, for example an irrigation pipe, including: ejecting at least one piece, for example a dripper, from an ejection unit, advancing the at least one dripper inside the irrigation pipe by a dripper advancing unit, lifting the dripper towards the inner surface of the irrigation pipe by using a lifting device such that the dripper is parallel or substantially parallel to this inner surface of the irrigation pipe on impact with this inner surface. The method according to the invention allows also coordination between the lifting device, the ejection unit and the dripper advancing unit such that the dripper spacing can be maintained in tight tolerances.

  • Publication number: 20050167892
    Abstract: Method, for manufacturing a composite pipe (CP) with a tubular wall, this wall comprising at least one extruded tubular part (1), referred to as the first tubular part (1), this first tubular part (1) being made up of a first polymeric material (100), this method being characterized in that the step of extruding the first tubular part (1) of a first polymeric material (100) involves the use of a first polymeric material (100) of the type capable of being cross-linked by infrared radiation, and this step of extruding the first tubular part (1) of said material is immediately followed by a step of irradiating the extruded first tubular part (1) with infrared radiation in order to accomplish said cross-linking reaction.
