A system and method for teaching music both visually and tactilely. In one embodiment, the invention comprises blocks shaped to resemble musical symbols used to compose music, including time signatures, notes, rests, and dots. Each of the blocks are relative in thickness such that for a given time signature, the correct rhythm for a given measure can be determined by laying one or more of the notes, rests and dots one over the other to see if their combined thickness is equal to that of a preselected time signature. The thickness of the block shaped to resemble the time signature is such that it only allows the correct number of blocks shaped as notes, rests or dots to be of equal thickness to thereby determine the correct rhythm. In addition, the correct rhythm can be determined by simply reading the shaped blocks as one would read music. The use of the shaped blocks having relative thicknesses allows a student to learn rhythm by trial and error and does not necessarily require that the student understand complex music theory. In addition, the blocks can be used by the student when clapping the correct rhythms. Other musical notation can be represented by blocks as well such as bar lines and slurs.

Systems and methods for bookmarking multimedia documents include displaying multiple multimedia streams, creating bookmarks comprising time signatures and snapshots of each multimedia stream based upon single action cues from a user, associating snapshots with portions of multimedia streams, displaying bookmarks and displaying portions of a multimedia stream associated with selected snapshots.

A measuring device is provided with a signal generator and a signal receiver, which is located at a measurable distance from the signal generator. The signal generator is designed for the emission of at least two signal beams covering in given relationship to each other an area and the signal receiver is designed for the time-resolved reception of the signal beams in such a manner that the generator-receiver distance can be determined from the time signature of the signal beam reception.

A system is described that permits identified musical phrases or themes to be synchronized and linked into changing real-world events. The achieved synchronization includes a seamless musical transition—achieved using a timing offset, such as relative advancement of an significant musical “onset”, that is inserted to align with a pre-existing but identified music signature, beat or timebase—between potentially disparate pre-identified musical phrases having different emotive themes defined by their respective time signatures, intensities, keys, musical rhythms and / or musical phrasing. The system operates to augment an overall sensory experience of a user in the real world by dynamically changing, re-ordering or repeating and then playing audio themes within the context of what is occurring in the surrounding physical environment, e.g. during different phases of a cardio workout in a step class the music rate and intensity increase during sprint periods and decrease during recovery periods.

A method is provided of authenticating a digitally signed message. A chain of messages is generated. A Winternitz pair of keys is generated for each respective message. A sequence number is assigned to each of the messages. Each of the sequence numbers cooperatively identify an order of Winternitz verifiers assigned to each of the messages. A signature to a first message in the chain of messages is signed using a digital signature algorithm private key. Signatures to each of the following messages in the chain of messages are signed using both Winternitz private keys and digital signature algorithm private keys. The signed messages are broadcast from a sender to a receiver. The first signed broadcast message is authenticated at the receiver by verifying the digital signature algorithm signature. At least some of the following signed broadcast messages are authenticated at the receiver by verifying only the Winternitz signature.

A method, computer program product, system and apparatus are presented for reducing wasted bandwidth due to supercasting multicast cells through a router switch fabric. In one embodiment of the present invention, signatures of a switch fabric destination address are generated and compared. A signature is an information-rich representation of the fabric destination address that is generated using the fabric destination address. Therefore, supercasting can be minimized by combining fabric destination addresses with like signatures. Aspects of the present invention include generating the signatures using random permutation maps of the set of switch fabric ports or determining intersections of a fabric destination address with a selection of subsets of the switch fabric ports. Signature-based solutions for supercast minimization can be performed in a time-efficient manner and be implemented online, while solutions that can generate a more optimal solution but may take a longer time to perform, such as row-clustering, can be implemented off-line. A further aspect of the invention, incorporates an off-line row-clustering supercast minimization method with an on-line signature-based supercast minimization method.

A portable diagnostic apparatus for performing diagnostic testing on a circuit breaker includes a number of sensor devices structured to generate a number of sensed parameter signals relating to operation of the circuit breaker during an operational sequence, a number of auxiliary input connectors structured to receive a number of auxiliary data signals from the circuit breaker, the number of auxiliary data signals relating to and being generated in response to the operation of the circuit breaker during the operational sequence, and control and diagnostic circuitry. The control and diagnostic circuitry is structured to control operation of the portable diagnostic apparatus, receive the number of sensed parameter signals and the number of auxiliary data signals, and generate a time signature based on the number of sensed parameter signals and the number of auxiliary data signals.

A security device of this invention includes a nonvolatile storage unit 22 for storing a validity check unit including a counter updated every time signature function means 30 is called up, a volatile storage unit 24 for reading and storing a counter array out of an external nonvolatile storage unit storing the counter array, in which the counter array is obtained by coupling a hash value generated for each signature key with a signature number counter for counting the number of signatures performed by use of the signature key, and a hash function unit 28 for reading the counter array out of the volatile storage unit 24, generating the hash value, and transferring the hash value to the validity check unit for a validity check.

The method comprises the following steps - introducing a low amplitude air pressure transient into the drainage and vent system of a building in order to propagate a pressure wave from a fitting (6) into a stack (1) and the network of the drainage system; - recording the passage of said transient by means of an air pressure transducer (7) located near the fitting (6) or introduction area of the transient; - recording the successive pressure reflections of the transient from each drain pipe (2) of the network of the drainage system; - establishing a pressure versus time signature recorded by the pressure transducer (7) and sending those signals to a central data acquisition system; - the pressure transient is propagated throughout the network at an acoustic velocity and is reflected by each and every pipe termination of the network so as to establish a characteristic reflection coefficient for each pipe termination; - said characteristic reflection coefficient is compared with testing results performed initially in a perfect network with no dry trap defects or leakage's and in case a different signature of the pressure trace is recorded, the point of diversion will be determined at the time at which the reflection from the altered pipe end termination arrives at the air pressure transducer so that the comparison of this defect trace with the stored defect free signature yields that time and, as the wave speed is known, the determination of the distance from the pressure transducer to the defective trap or seal.
