Abstract: An inflatable face seal (1?; 30?) for a respiratory mask, the inflatable face seal comprising an annular air-tight hollow portion (12?; 40?) where a cross section through one section of the annular hollow portion (12; 40) comprises a bonded joint (11; 41) which joins two overlapping flanges (6,7; 35,36). The two flanges are bonded together such that an inwardly facing surface (10; 39) of a first flange (6; 35) of the two overlapping flanges is in contact with an outwardly facing surface (9; 38) of a second flange (7; 36) of the two overlapping flanges. In this way, the bond is strong and only exposed to shear stresses when the annular air-tight hollow portion is exposed to increased pressure.

Abstract: A method for controlling the effective heat transfer from a storage unit (1). During gas release from storage material (3) in the storage unit the storage material is heated by a heater (2). During re-saturation of the storage material (3) with gas the heater is off. Controlling of the effective heat transfer from the storage unit (1) is performed, during gas release, by ceasing convection of a convection gas and, during re-saturation, by performing or enabling convection of a convection gas to cool the storage unit (1).

Abstract: The present invention concerns the field of broadcast encryptionmethod, i.e. a method to organize the distribution of keys into a group of users so that it is possible to manage the revocation of one member of the group in an efficient way. The proposed solution is a private encryption key ciphertext constant collusion-resistant broadcast encryption. The main idea behind the invention is to mix the notion of efficient tree-based key derivation (also called subset management) with individual and personalized key blinding thus achieving a full collusion-resistant broadcast encryption system. The key de-blinding is performed at the last moment thanks to a cryptographic technique called pairings (also known as bilinear maps) resulting in a global key commonly shared by all authorized (non-revoked) devices.

Abstract: A PDMA terminal (1000) establishes communication by forming a plurality of spatial paths to another single radio apparatus. A plurality of antennas constituting an array antenna are divided into a plurality of subarrays corresponding to the plurality of spatial paths respectively. An adaptive array processing unit (USP) can perform an adaptive array processing for each of the plurality of subarrays. A memory (MMU) stores in advance information on the number of antennas associated with the number of spatial paths that can be formed by the array antenna. A control unit (CNP) controls a processing to transmit possible multiplicity information to another radio apparatus at a prescribed timing.
