Abstract: There is disclosed a scheme for secure distribution of content in a manner that users will perceive as fair, while enforcing restrictions on the use of the content in accordance with the intentions of the content originator. The scheme provides a method of encrypting data set comprising: generating a seed value; seeding a pseudo-random number generator with the seed value; creating an encrypted data set by combination of the output of the pseudo-random number generator with the data set; and encrypting the seed value and associating the encrypted seed value with the encrypted data set. In a typical embodiment, the encrypted seed and the encrypted data are combined in a single file and conveyed to a media player that includes decryption core compatible with the encoding encryption scheme. Also disclosed is a content distribution system and a media player to take advantage of such an encryption scheme and a media player for use with the scheme.

Abstract: A content mining system and process utilizes a combination of term recognition and rules-based activity-event classification, performed using a modular database that defines one or more vertical markets or information sectors, to identify sector relevant evidence. The primary elements of the identified evidence are scored in a manner that rates the relevance of a content item with respect to a set of identified nominative entities, a set of activity-based event categories, further associated as sets of entity-event pairs. A database constructed of the scored information provides a relevancy indexed repository of the original unstructured content items.

Abstract: A computing system and architecture is provided that affects and extends services exported through application libraries. The system has an operating system having an operating system kernel having OS critical system elements (OSCSEs) for running in kernel mode; and, a shared library having critical system elements (SLCSEs) stored within the shared library for use by the software applications in user mode. The SLCSEs stored in the shared library are accessible to the software applications and when accessed by a software application forms a part of the software application. When an instance of an SLCSE provided to an application from the shared library it is ran in a context of the software application without being shared with other software applications. The other applications running under the operating system each have use of a unique instance of a corresponding critical system element for performing essentially the same function, and can be run simultaneously.

Abstract: A modulated burner combustion system that prevents the use of components that were originally not commissioned for use in the system. The present invention uses actuators that contain unique stored identification numbers. When the system is initially configured or commissioned, the unique identification numbers of the actuators are stored in nonvolatile memory in a fuel/air controller. When the system is brought on line, the fuel/air controller microprocessor initially sends false IDs to the actuator together with test control signals to determine if the actuator operates in response to the false identification numbers. If the actuator does operate in response to the false identification numbers, that is an indication that the system has been tampered with and the system is, consequently, shut down. Subsequently, the true identification numbers are transmitted to the actuators with test control signals.

Abstract: A monolithic integrated high resolution analog-to-digital converter based on a charge balancing process, characterized in that the output of a charge balancing integrator is connected to the control input of a pulse width modulator. An output of the pulse width modulator controls the temporal activity of the feedback signal in the charge balancing integrator. The output of the pulsewidth modulator is also connected to a digital calculation circuit which evaluates the pulse width result of the conversion. The input of the analog-to-digital converter is connected to one input of the charge balancing integrator and the feedback signal from the pulse width modulator is connected to the other input.

Abstract: A circuit checks for coincidence of a data word with a reference data word by means of EXOR gates per digit of the two data words, and a non-coincidence is permitted in a number of digits (m). The output signal that appears at the output of the circuit is the result of the current flowing therein, with the sign thereof being indicative of either a coincidence or a non-coincidence. For this purpose, the individual outputs of the EXOR gates serve to activate switch transistors with the aid of which standard currents (i) are caused to flow from the output, via an N-multiple current source, to the zero point of the circuit (ground). On the other hand, via a first P-current mirror, a current mi and, via a second P-current mirror, a current i/2 are fed to the output. By means of the N-multiple current source, the current mi is impressed upon the current input of the first P-current mirror.

Abstract: A current switch for use in digital-to-analog converters having high dynamic accuracy includes first and second electronic switches, the first of which connects either a constant-current source or a constant-current sink to an output terminal. The output terminal is connected to a low-pass filter. When the constant-current source is connected to the output terminal, the second switch connects the constant-current sink to a reference-voltage source. When the constant current sink is connected to the output terminal, the second electronic switch connects the constant current source to the reference-voltage terminal. This antiphase switching of the two electronic switches is controlled by a control circuit to which a clocked signal and a clock signal are applied. The clocked signal is, for example, a pulse-density-modulated signal which appears as a demodulated signal at the output of the low-pass filter.

Abstract: For continuously adjusting the time delay of this delay line the latter is designed to consist of stages (l, n) which are of the same kind, and contains per stage a conventional CMOS inverter to which, on the P-channel transistor side, a P-channel constant-current transistor and, on the N-channel transistor side, an N-channel constant-current transistor is connected in series. The N-channel constant-current transistors form part of an N-channel multiple current mirror, and likewise, the P-channel constant-current transistors form part of a P-channel multiple current mirror. Among each other all transistors of the two current mirrors are capable of conducting currents which are equal in terms of magnitude and equal in relation to an adjustable reference current.

Abstract: For the purpose of achieving a small as possible distortion factor in the case of high-frequency input signals, the load resistors in this differential amplifier are designed as depletion resistors (DEPRs) of the type known per se. Likewise, in the common source circuit, there is provided the further DEPR, with the two transistors thereof having the same width-to-length ratios. Moreover, each of the amplifier transistors has a constant-current transistor of its own which, together with both the transistor and the DEPR, as well as the transistor which is connected as a diode, form the constant-current circuit. The respective width-to-length ratios of the transistors of the DEPRs differ from one another.
