| 20080222427 | DEVICE AND METHOD WITH REDUCED INFORMATION LEAKAGE - The invention is directed to a data-processing system comprising a processor and first encrypted information in a first persistent memory whose level of information leakage is higher than that of a second persistent memory. In the second persistent memory is stored a first cryptographic key for decrypting the first encrypted information, thereby generating therefrom first unencrypted information that is usable by the processor for executing an operation. The same cryptographic key may also be used for encrypting the first unencrypted information, thereby generating the first encrypted information. It is also directed to a method of processing such a data-processing system with an operating system, comprising a writing step for writing first unencrypted information into the first persistent memory, an encryption step for encrypting the first unencrypted information under use of the first cryptographic key, creating therefrom first encrypted information in the first persistent memory, and an access-limitation step for setting the data-processing system to a state in which writing into the first persistent memory is controlled by the operating system. It also relates to a method of executing an operation on such a data-processing system comprising a decryption step for decrypting the first encrypted information under use of the first cryptographic key, thereby generating therefrom first unencrypted information and an execution step for executing an operation by the processor, using the first unencrypted information. | 09-11-2008 |
| 20080226076 | PROVIDING A USER DEVICE WITH A SET OF ACCESS CODES - A method for providing a user device with a set of access codes comprises, in the user device, storing an encryption key and an identification code, and sending a message containing the identification code to a server via a communications network. In the server, an encryption key is stored corresponding to the key stored in the user device, allocating the set of access codes on receipt of the identification code from the user device. A look up function is performed based on the identification code received in the message to retrieve the key from storage. The set of access codes is encrypted using the retrieved key to produce an encrypted set. A message containing the encrypted set is sent to the user device via the network. In the user device, the encrypted set received from the server is decrypted using the key in storage, and storing the decrypted set of access codes for use by a user of the user device. | 09-18-2008 |

| 20120098949 | SPIM MICROSCOPE WITH A STED LIGHT SHEET - A STED-SPIM-microscope (Selective Plane Imaging Microscopy) having a y-direction illumination light source and a z-direction detection light camera. An x-scanner generates a sequential light sheet by scanning the illumination light beam in the x-direction. By optionally turning on a STED deactivation light beam the light sheet can optionally be made thinner and therefore the optical resolution can be increased. | 04-26-2012 |
| 20120099190 | SPIM Microscope with a sequential light sheet - A SPIM-microscope (Selective Plane Imaging Microscopy) having a y-direction illumination light source and a z-direction detection light camera. An x-scanner generates a sequential light sheet by scanning the illumination light beam in the x-direction. By an illumination optics having a zoom optics that is provided in the beam path of the illumination light beam the focal length of the illumination light beam can be varied. | 04-26-2012 |

| 20090015314 | HIGH FREQUENCY EXCITATION SYSTEM - A power module is adapted to be connected to a voltage source and to supply power to a load. The power module includes a power transistor; and a gate controller for driving the power transistor. The gate controller includes a gate transformer, and an impulse generator that extends a negative drive phase of a gate voltage to the power transistor relative to a positive drive phase of the gate voltage to the power transistor. | 01-15-2009 |
