Abstract: A location signaling device comprising a wing balloon for signaling a location. The wing balloon is fixed to a tether line that itself is fixed to the location to be signaled. The wing balloon has an inflatable aerodynamically shaped hollow body to be at least partly be filled with a lighter-than-air gas and having a wing attack surface for air flowing relative to said wing balloon. The floating aloft of said wing balloon is supported by said air flow. When the wing balloon is inflated, a flexible wing portion is passively variable. The stronger the wind, the less attack is given. Thus, the dragging force on the tether line is generally static.

Abstract: A method and a device for carrying out electronic transactions. A sender produces, under his own full control, a transaction message in a smart card (1) and provides the message with his digital signature in the card for subsequent output and transmission.

Abstract: A user verification system responding to voice commands comprises a control unit (11, 21), input means (221) for receiving voice commands and output means (224, 225) for presenting information to the user. The control unit (21) is adapted to create a hash value from one or more received voice commands which is presented to the user by use of the output means (224, 225). The input means (221) is adapted to receive the hash value from the user in form of a spoken message, and the control unit is further adapted to verify the identity of the user based on the received hash value.

Abstract: A heat transport apparatus, comprises an absorbator (204), a desorbator (202), a compressor (206), a liquid pump (212), a heat exchanger (216), a restriction element (122) and a two-component refrigerant (203′, 205′), i.e. a liquid and a gas absorbed in the liquid. The characteristic feature is that the refrigerant comprises a lubricant. In a second aspect the invention relates to a two-component refrigerant suitable for use in a heat pump of the absorption-compression type, comprising a lubricant as a liquid component, and a gaseous component absorbable in the lubricant.

Abstract: The invention relates to a device for preventing unauthorized use of card- or disc-shaped proofs of legitimacy and/or data carriers, such as ATM cards, credit cards and flexible discs, comprising a cover or case-shaped device (1) or the like having at least one pocket or the like adapted to receive at least a portion of at least one card, disc, etc., actuators and control means (4) arranged in said pocket, said control means being adapted to control said actuators and preferably being of the code lock type and comprising one or more means which, when actuated in a certain sequence or in a certain combination, are adapted to control said actuators.The novelty of the invention resides in that said actuators comprise means (17, 20x, 27) which are activatable when an attempt at gaining access is made without proper actuation of said control means and which, in the event of such an attempt at unauthorized access, are adapted to permanently mechanically damage said card, disc etc. and/or the data carried thereon.
