Abstract: The invention relates to a learning promotion system, comprising: a learning promotion device with measurement means, for connecting to a workpiece and for measuring one or more parameters associated therewith, and work analysis means. Processing means are provided that a) determine, based on a model stored in a memory and the measurements, a state of the workpiece; b) determine, based on the state of the workpiece and the model, a learning intervention suggestive of an action to be performed by the participant in order to progress the work to be performed, so as to bring the workpiece to another state which is equal to or which is closer to a completed state as defined by the model; and c) control an interface to provide user output corresponding to the learning intervention. In an embodiment, means are provided that determine interactions taking place between participants and resources to perform learning analytics.

Abstract: A random number generator that generates random numbers based on measurements of one or more environmental quantities. The random number generator includes a first sensor for generating a first sequence of digital values representing measurements of a first environmental quantity at successive times. A first compressor that provides a first sequence of compressed values having a lower internal correlation than the values of the first sequence of digital values compresses the sequence of digital values. The random number generator generates an output random number via a circuit for generating a random number from an input sequence of digital values, the input sequence being a function of one of the first sequence of compressed values. The circuit may utilize a hash function to provide further security. In addition, the circuit includes a blocking circuit for preventing the generator from outputting a random number if the input sequences fail a predetermined test.

Abstract: A digital audio system configured to facilitate a collaborative audio session comprises a first digital audio device operable by a first user, a second digital audio device operable by a second user independently of the first digital audio device, and a server configured to communicate with the first digital audio device and the second digital audio device over a network, receive a request from at least one of the digital audio devices for participation in a collaborative audio session, and facilitate communication between the first digital audio device and the second digital audio device.

Abstract: An exemplary apparatus for providing VoIP services comprises: (a) a telephone hardware interface connectable to a POTS network; (b) a VoIP gateway connectable to a VoIP network; (c) a bridge operable to interconnect a POTS session over the telephone hardware interface with a VoIP session over the VoIP gateway; and (d) an input/output interface that is connected to at least one of the telephone hardware interface, the VoIP gateway, and the bridge, and which is also connectable to a telephone.
