  • Patent number: 7127618
    Abstract: A security system purposely damages at least a portion of content material, using a damaging process that is easily reversible, until a verification of authorization is determined. While the authorization to access the content material is in an unverified state, an undamaged version is provided for immediate rendering, but any stored versions of the content material is stored in the damaged state. When the authorization is verified, the damaging process ceases, and the stored damaged version is repaired, thereby allowing unimpeded subsequent access to the authorized content material. If sufficient evidence is obtained to warrant a determination that the content material is unauthorized, the access to the material is terminated, and any stored content material remains in the damaged state, thereby precluding subsequent access to the unauthorized content material.

  • Patent number: 7127065
    Abstract: In a method and arrangement for embedding and detecting a watermark in an information signal, the embedded watermark (Wi) is selected (13) from a plurality of watermarks (W1 . . . WN) in dependence upon a property P of the signal. An example of such a property is the distribution of luminance values of the current video image as calculated by an analysis circuit (12). The corresponding watermark detector performs the same operation: the watermark being looked for depends on the same signal property. It is achieved with the invention that the embedded watermark changes from time to time as a function of the information signal content, so that it cannot easily be hacked.

  • Patent number: 7113038
    Abstract: A switching power amplifier of class D has a switching stage for generating a block wave signal by alternately switching the block wave signal between supply voltages. A filter (24, 25) generates a power output signal (22) corresponding to an input signal to be amplified, which is coupled to a linear input (19) that is free of hysteresis. A control circuit (27, 28, 29) provides feedback between the output power signal and the linear input for controlling both the gain in the operational frequency range and also the alternately switching of the switching stage. Hence, the amplifier oscillates controlled via the same feedback loop that also controls the operational behavior of the amplifier, resulting in low output impedance and low distortion.

  • Patent number: 7110336
    Abstract: In methods and an optical recording apparatus using these methods, an optimum write power of a radiation beam in the apparatus is set by writing a series of test patterns on the optical recording medium, forming a read signal from the patterns and processing the read signal. Such processing involves fitting a function, preferably a straight line, to parameters obtained from the read signal without having to perform a differentiation step.

  • Patent number: 7103829
    Abstract: A method of selecting a generator matrix (G) for encoding information words (m) including information symbols (m1, m2, mk) into codewords (c) of a code (C) provides an enhanced error correction capability if at least one information symbol (m1, m2, m3) is known a priori to a decoder decoding received, possibly mutilated codewords (r). In order to design a code of which the correction power is enhanced if some information symbols are known to the decoder prior to decoding, the generator matrix (G) is selected such that the minimum Hamming distance of at least one subcode (C?) of the code (C) is larger than the minimum Hamming distance of the code (C), and that a subcode generator matrix (G?) of the at least one subcode (C?) is derived from the generator matrix (G) of the code (C) by omitting the at least one row from the generator matrix (G) corresponding to the at least one a priori known information symbol (m1, m2, m3).

  • Patent number: 7091997
    Abstract: The progress of transferring an electronic object from a sending handheld to a receiver is graphically represented as an object gradually sliding out of view on the display of the sender and gradually sliding into view on the display of the receiver. A gravity sensor in the sending handheld is used to determine the transmission's data rate. This visual feedback is an ergonomic feature for, e.g., electronic toys.

Alternatively, the modulated parts include a second frequency, which is substantially different from the first frequency, for encoding data bits of the record carrier information, the second frequency being a integral multiple N of the first frequency. A recording and/or playback device has a device for recording/reading the information blocks and for reading the record carrier information.

  • Patent number: 7075519
    Abstract: In a method for entering a character sequence consisting of one or more characters into an electronic device including keys for entering keystrokes by a user as well a display panel for presenting information to the user, wherein a group of characters is presented on the display panel in the form of a matrix composed of rows and columns, at least one specific character is pointed by a cursor which is movable through the matrix, and the character sequence is constructed by pointing out consecutive characters one by one by the cursor, and the character is entered by a keystroke. In order to enter a specific character from the character sequence, the cursor moves automatically in a first direction through a specific row or column, thereby sequentially pointing out the characters in the specific row or column; the automatically moving cursor can be moved towards the column or row, respectively, of the specific character by one or more first and/or second keystrokes.

    Abstract: The invention relates to a method and devices for storing and reading data (5, 6) on a storage medium (17). In order to allow compatibility between different file systems (JAFS, UDF) data structures are stored in a first administrative area (10) as belonging to the first file system (JAFS) and a second administrative area (12) belonging to the second file system (UDF). Thus, a so-called bridge disc is achieved that may be read in the different file systems.
