System for controlling a door enabling driving from an initial position of its travel in a first direction at a speed v1 as far as a final position, said control system comprising a safety function comprising means for keeping a door in operation despite its having suffered an impact against an obstacle situated on its travel and enabling it to continue its initial movement automatically as soon as said obstacle is removed, through a design reconciling a sufficiently high normal speed of movement v1 of the door with the intention to prevent damage both to the obstacle and to the door by reducing the speed to v3<v1 close to the stored position of the impact.

The transparent polycrystalline optoceramic has single grains with a symmetric cubic crystal structure and at least one optically active center. The optoceramic has the following formula: A2+xByDzE7, wherein 0≦x≦1.1, 0≦y≦3, 0≦z≦1.6, and 3x+4y+5z=8, and wherein A is at least one trivalent rare earth cation, B is at least one tetravalent cation, D is at least one pentavalent cation, and E is at least one divalent anion. The method of making the optoceramic includes preparing a powder mixture from starting materials, pre-sintering, sintering and then compressing to form the optoceramic. Scintillator media made from the optoceramic are also described.

This disclosure relates to controlling unwanted traffic to a device (40) in a communication network (30). The idea is to provide a more fine-grained control of incoming packets or connection attempts, by using an inclusive firewall (10) i.e. a firewall operating on “white-listed” traffic to a device (40). The disclosure, relates to a method for controlling a data flow to a device in a communication network, using a firewall located in the path between said device and a source node. The method comprises receiving (210), in said firewall, at least one data packet of said data flow. The firewall then reads (220), a predefined selection of bits of said at least one data packet, wherein the selection of bits is contained in at least one field of said data packet. The at least field or fields, including the selection of bits, carry a first type information. The firewall then forwards (240) the at least one data packet to the device, if selection of bits fulfills a policy of said device. The policy is defining requirements by which packets to said device are solicited. Hence, the solicitation of packets is a second type of information carried by said selection of bits. The disclosure further relates to a methods controlling a data flow, as well as to a firewall (10), a source (20) and a device (40).
