  • Publication number: 20070127698
    Abstract: A method and apparatus for routing calls for a subscriber based on the identification of the calling party or the originating line. Generally, the present invention operates to identify a calling party or originating line and then select a routing list based on this identification. Once a routing list has been selected, the call will be routed to the destination in the routing list. More specifically, when a call is received, an inquiry is made regarding the identity of the calling party or calling line. If the identification can be determined, then an attempt to retrieve a routing list associated with this identification is made. If a routing list has been provided for the identified party or line, the routing list will be retrieved. If a routing list has not been provided for the identified party or line, a default routing list will be selected for routing the call.

  • Publication number: 20070127718
    Abstract: A method and apparatus for generating true random numbers by way of a quantum optics process uses a light source to produce a beam which illuminates a detector array. The detectors of the array are associated with random numbers values. Detection of a photon by one of the detectors yields a number whose value is equal to that associated with the detector. This procedure is repeated to produce sequences of true random numbers. The randomness of the numbers stems from the transverse spatial distribution of the detection probability of the photons in the beam. If the array comprises two detectors, the true random numbers produced are binary numbers. The process can be sped up using an array having pairs of two detectors. Using an array having more than two detectors also allows generating true random numbers of dimension higher than two. The primary object of the invention is to allow generating true random numbers by way of a quantum optics process.

  • Publication number: 20070127719
    Abstract: The invention generally relates to management of cryptographic key generations in an information environment comprising a key-producing side generating and distributing key information to a key-consuming side. A basic concept of the invention is to define, by means of a predetermined one-way key derivation function, a relationship between generations of keys such that earlier generations of keys efficiently may be derived from later ones but not the other way around. A basic idea according to the invention is therefore to replace, at key update, key information of an older key generation by the key information of the new key generation on the key-consuming side. Whenever necessary, the key-consuming side iteratively applies the predetermined one-way key derivation function to derive key information of at least one older key generation from the key information of the new key generation. In this way, storage requirements on the key-consuming side can be significantly reduced.

    Abstract: This invention concerns a distributed stereo audio system. Distributed stereo audio systems are used to provide stereo sound to several rooms or areas from a single source of signal. The system includes two or more speakers for the broadcast of stereo audio signals; a source of stereo audio signals; a stereo amplifier to amplify stereo audio signals and drive the speakers; and a mains operated electrical power supply to provide power to the amplifier. The amplifier is located in the same room as the speakers, and remote from the signal source and power supply. The amplifier is connected to the signal source and power supply by means of a category 5 four pair twisted cable which provides, in respective twisted pairs, right channel audio signals from the signal source to the amplifier, left channel audio from the signal source to the amplifier, DC power from the power supply to the amplifier, and control signals from the amplifier to the signal source.

    Abstract: For generating a parametric representation of a multi-channel signal especially suitable for low-bit rate applications, only the location of the maximum of the sound energy within a replay setup is encoded and transmitted using direction parameter information. For multi-channel reconstruction, the energy distribution of the output channels identified by the direction parameter information is controlled by the direction parameter information, while the energy distribution in the remaining ambience channels is not controlled by the direction parameter information.

  • Publication number: 20070127735
    Abstract: A sound characteristic parameter is obtained for an audio signal to be analyzed by analyzing the signal by means of a sound characteristic parameter analyzing section arranged upstream relative to a similarity determining section. A sound signal operation as retrieving key is read out from a retrieving key storage area of a retrieving key memory by a retrieving key audio signal reading section and analyzed by a retrieving key sound characteristic parameter analyzing section to obtain a retrieving key sound characteristic parameter. The similarity determining section compares the sound characteristic parameter obtained from said sound characteristic parameter analyzing section and the retrieving key sound characteristic parameter obtained from said retrieving key sound parameter reading section and determines the similarity of them to retrieve a part of the audio signal to be analyzed that resembles the audio signal operating as retrieving key and obtained from the sound source of the retrieving key.

  • Publication number: 20070127738
    Abstract: The present invention is directed to an audio signal reproducing system comprising a speaker system including at least two drive units or more which are divided or separated by frequency band. In this system (1), a signal processing unit (3) serves to add inverse characteristic to an inputted digital audio signal as correction characteristic of impulse response of speaker system (7). Thereafter, a D/A converter converts the digital audio signal thus obtained back into an analog signal. A power amplifier (5) amplifiers the analog signal thus obtained to deliver the analog signal thus amplified to the speaker system (7). The speaker system (7) outputs a signal at low frequency band that a LPF (8) has passed as sound wave of low pitched sound from drive surface (9a) of a low frequency drive unit (9), and outputs a signal at high frequency band that a HPF (10) has passed as sound wave of high pitched sound from drive surface (11a) of a high frequency drive unit (11).

  • Publication number: 20070127743
    Abstract: Two control voltages are generated, one increasing and another decreasing, in response to the rise of the voltage of a condenser of a common time-constant circuit. Based on the two control voltages, a first and a second currents are formed, from which four different combinations of currents are established. By feeding one of four combinations to each of multiple differential output amplifier circuits each having a feedback resistor, the multiple output amplifier circuits can be individually started up or shut down without generating popcorn noise, using only one single time constant circuit.
