  • Patent number: 8978408
    Abstract: A liquefier for a heat pump includes a liquefier space and a process water tank. The process water tank is arranged within the liquefier space such that it is substantially surrounded by liquefied working fluid. A wall of the process water tank, however, is spaced from a wall of the process water tank so that a gap formed to communicate with the region of the heat pump in which compressed gas is present is obtained, so that the process water tank is thermally insulated from the space for liquefied working fluid via this gas-filled gap. The liquefier itself may also be surrounded by the gas region, in order to provide for inexpensive insulation of the liquefier.

  • Publication number: 20140075978
    Abstract: An evaporator or a condenser includes a surface on which the operating liquid is arranged. Further, turbulence generators are provided to generate turbulences in the operating liquid located on the operating surface. In the condenser, alternatively or additionally, a laminarizer is present to make the vapor stream laminar provided by the compressor. On the evaporator side, the evaporation efficiency is increased and, on the condenser side, the condenser efficiency is increased, which may be used for a substantial reduction in size without loss of power of these components, in particular for a heat pump for heating a building.

  • Patent number: 8484991
    Abstract: A heat pump having a cooling mode includes a cooling evaporator coupled to an advance flow and a backflow. The cooling evaporator is brought to a pressure such that a vaporization temperature of the working liquid in the backflow is below a temperature of an object to be cooled to which the backflow may be thermally coupled. In this manner, an area having vapor at high pressure is generated. This vapor is fed into a dynamic-type compressor which outputs the vapor at a low pressure and provides electrical energy in the process. The vapor at low pressure is fed to a cooling liquefier which provides vapor liquefaction at a low temperature, this temperature being lower than the temperature of the object to be cooled. The working liquid removed from the cooling evaporator due to the vaporization is refilled by a filling pump. The heat pump having a cooling mode also results when a specific heat pump is operated in the reverse direction, and provides cooling without any net use of electrical energy.

  • Patent number: 8369520
    Abstract: A cryptography processor includes a central processing unit and a co-processor, the co-processor comprising a plurality of calculating subunits as well as a single control unit which is coupled to each of the plurality of calculating subunits. A cryptographic operation is distributed among the individual calculating subunits in the form of sub-operations by the control unit. The central processing unit, the plurality of calculating subunits and the control unit are integrated on a single chip, the chip comprising a common supply current access for supplying the plurality of calculating subunits and the control unit with current. Due to the arrangement of the calculating subunit in parallel, on the hand, the throughput of the cryptography processor is increased. On the other hand, however, the current profile that may be detected at the supply current access is randomized to such an extent that an attacker can no longer infer numbers processed in the individual calculating subunits.

  • Publication number: 20110036100
    Abstract: A heat pump comprises an evaporator for evaporating water as a working liquid so as to produce a working vapor, the evaporation taking place at an evaporation pressure of less than 20 hPa. The working vapor is compressed to a working pressure of at least 25 hPa by a dynamic-type compressor so as to then be liquefied within a liquefier by direct contact with liquefier water. The heat pump is preferably an open system, wherein water present in the environment in the form of ground water, sea water, river water, lake water or brine is evaporated, and wherein water which has been liquefied again is fed to the evaporator, to the soil or to a water treatment plant.

  • Patent number: 7831650
    Abstract: In a method for modular multiplication using a multiplication look-ahead process for computing a multiplication shift value and a reduction look-ahead process for computing a reduction shift value, a modulus is first transformed into a transformed modulus that is greater than said modulus. The transformation is carried out such that a predetermined fraction of the transformed modulus has a higher-order digit with a first predetermined value that is followed by at least one low-order digit having a second predetermined value. During the iterative working off of the modular multiplication using the multiplication look-ahead process and the reduction look-ahead process, the transformed modulus is utilized so as to obtain at the end of the iteration a transformed result for the modular multiplication. Finally, the transformed result is re-transformed by modular reduction using the original modulus.

  • Patent number: 7782108
    Abstract: A flip-flop device for storing and outputting a data value includes a controllable memory element configured to be open as a function of a control pulse, a feedback means for comparing a data value present at the memory element and the data value output by the memory element, and for outputting a comparison signal, and a control pulse generator for generating the control pulse as a function of the comparison signal, so that the control pulse generator is put in an activated state when the comparison signal is high, so as to then, in the activated state, open the memory element in response to a clock event. The memory element will then be closed again when the comparison signal indicates that the same values are present at the output and at the input of the memory element.

  • Patent number: RE41734
    Abstract: A read-only memory having a multiplicity of memory cells whose contents can be read out with appropriate addressing by word, bit and source lines. The read-only memory is distinguished by the fact that the memory cells which can be addressed via an individual word line are divided into a multiplicity of groups, to each of which a separate common source line is assigned. Accordingly, a group-by-group read-out of the memory cells which can be addressed via an individual word line is carried out.
