| 20110043807 | METHOD AND APPARATUS FOR TURBIDITY MEASUREMENT - A method for turbidity measurement in a measured medium uses a turbidity sensor, which comprises at least a first and a second emitter and at least a first and a second detector. The first and the second emitters are excited one after the other to produce light signals directed into the measured medium; wherein each light signal travels along a first propagation path through the measured medium to the first detector, and is converted by such into a first detector signal; and travels along a second propagation path through the measured medium to the second detector, and is converted by such into a second detector signal. A turbidity value is ascertained based on the first and the second detector signals; wherein, by means of at least one additional detector, to which at least one of the light signals travels along an additional propagation path, an additional detector signal is ascertained, and, on the basis of the additional detector signal, the turbidity value is checked as regards its plausibility. | 02-24-2011 |
| 20110093232 | Method and arrangement for automatic calibrating of spectrometers - An arrangement as well as a method for calibrating a spectrometer for measuring spectral fractions of a substance in the context of chemometrics or chemometric processes with a spectrometric apparatus for measuring spectral fractions of the substance to be examined as well as with a calibration unit, by means of which a calibrating of the spectrometric apparatus and/or measurement data based on measured spectrometric data is performed, characterized by the following steps: a) measuring a totality of spectral fractions X and/or corresponding substance concentrations of the substance to be examined; b) storing the totality of the measured spectral fractions X in a memory module as spectrometric measurement data in the form of a multidimensional coefficient vector; c) automatic extracting, from the totality of the measured spectral fractions X, of spectral fractions X | 04-21-2011 |

| 20090019468 | Access control of media services over an open network - To ensure that media services are only provided to those authorized users or receiving devices, various conditional access mechanisms are provided to secure that media services are only received in those authorized. Different from a prior art conditional access system, an entitlement control message containing a master key can be sent directly to an ordering box. Depending on implementation, a secure session may be established between a server and an ordering box, such that all secured information including a master key may be transported. Further an ordering box does not need to possess a key or keys needed to decrypt an entitlement control message, such key(s) may be transported from time to time in a secure session established between the server and the ordering box. | 01-15-2009 |
| 20090031122 | Mechanism for restoring an apparatus to factory default - A mechanism for restoring an apparatus to factory default is disclosed. A reset mechanism is provided in an electronic apparatus and can be activated or pressed when the electronic apparatus is powered off. A detection circuit, when the apparatus is powered on, is configured to detect whether the reset mechanism has been activated when the apparatus was powered off. If it is determined that the reset mechanism was activated, the detection circuit activates a resetting process that sets the apparatus back to the factory default status. | 01-29-2009 |
| 20090031143 | Method and system for securing a disk key - In accordance with an embodiment of the present invention, a trusted client includes a non-volatile memory programmed with an encrypted disk key. The encrypted disk key in the non-volatile memory is encrypted with a master key of a security processor. Accordingly, encrypted data received by the central processor from a disk's security logic is forwarded to a security processor along with the encrypted disk key. The security processor decrypts the encrypted disk key and then decrypts the encrypted data, utilizing the disk key. The disk key is never available to the central processing unit in the clear. | 01-29-2009 |
| 20110023072 | MULTIPLE AUDIO STREAMS - A system and method for providing multiple audio streams for a video over a network such as the Internet. The system comprises a server that includes an encryption unit and a slicing unit, a plurality of boxes, and an ordering box. The server encodes multiple audio streams and a single video to be sliced into segments. The sliced segments of multiple audio streams and the single video are seeded to a number of the plurality of boxes. This may be repeated for other videos with multiple streams. When the ordering box makes a request for a single video with a single audio, then the number of boxes with segments of the requested video and multiple audio streams, filters and sends the requested video and requested single audio stream to the ordering box. Similarly, multiple closed caption streams can be handled and provided like the audio streams. | 01-27-2011 |
