  • Publication number: 20200025531
    Abstract: It is proposed to make a threat better visible for a defensive measure. In this context, the threat (2) should be imaged more intensely for the defensive measure. For the purposes of more effective imaging, provision is made for the threat to emit a stronger IR signature and thus be able to stand out sufficiently against the background for the defensive measure. The stronger IR signature is caused by heating a surface of the threat, which is realized by a laser weapons system. The defensive measure can better detect this heating and has an IR seeker head to this end.

  • Patent number: 9253723
    Abstract: A communication device for a remote switch has a control device designed to supply a preparatory signal for preparing a transmission process and a transmission signal for starting the transmission process. A memory device is designed to save one structural information and a parameter for different transmission protocols. A processing device is designed to supply data to be sent, read the structural information and the parameters from the memory device in response to the preparatory signal and, based on the data to be sent and the structural information, create a send packet, and output the send packet and the parameter in response to the transmission signal. A transmission device is designed to wirelessly emit a transmission signal representing the send packet with a transmission characteristic defined by the parameter.

  • Patent number: 9103919
    Abstract: A method is disclosed for transmission of register contents of a CT detector with hierarchical hardware structure, wherein the first hierarchy level is formed by a control unit containing a register table for the read-out register contents of FPGAs lying lower down in the hierarchy and an intermediate register store for register contents to be written. With each new reading, the new register contents for FPGAs lying lower down in the hierarchy arriving during the respective preceding reading from the central control at the control unit are forwarded to the next hierarchy level. With each new reading, the register contents of all FPGAs lying lower down in the hierarchy are re-entered into the register table of the control unit. Finally, in the event of a readout command transferred asynchronously from the central control, the register contents are read out exclusively from the register table.
