摘要： A portion of an audio signal is separated into multiple frames from which one or more different features are extracted. These different features are used, in combination with a set of rules, to classify the portion of the audio signal into one of multiple different classifications (for example, speech, non-speech, music, environment sound, silence, etc.). In one embodiment, these different features include one or more of line spectrum pairs (LSPs), a noise frame ratio, periodicity of particular bands, spectrum flux features, and energy distribution in one or more of the bands. The line spectrum pairs are also optionally used to segment the audio signal, identifying audio classification changes as well as speaker changes when the audio signal is speech.

摘要： The invention relates to a tele- and data communication system, including circuits containing transfer paths for data flows, and having functionality for error isolation of parts of the system. At least partially, where possible, parts of the circuits of the system are error isolated by logical partition into function blocks of two types. More particularly there is a first type, in which a complete corresponding function block need not necessarily become eliminated by an occurring error, and a second type in which the contrary is true. The transfer paths of a function block of the first type are isolated from each other for enabling shutting down such an erronous transfer path from traffic by software control.

摘要： Disclosed are several examples of an apparatus for connecting the free ends of two electrical power transmission lines having conductor strands disposed around a central, reinforcing core. The examples include an inner sleeve having a body defining an inner bore passing through an axially-extending, central axis, an outer rim surface disposed radially outward from the central bore, and one or more axially-extending grooves penetrating the body at the outer rim surface. Also included is an outer splice having a tubular shaped body with a bore passing coaxially through the central axis, the bore defining an inner rim surface for accepting the inner sleeve. The inner bore of the inner sleeve accepts the reinforcement cores of the two conductors, and the grooves accept the conductor strands in an overlapping configuration so that a majority of the electrical current flows between the overlapped conductor strands when the conductors are transmitting electrical current.

摘要： A radio communication apparatus is provided that enables degradation of error rate performance due to puncturing to be minimized when an LDPC code is used as an error correcting code. In this apparatus, a padding bit insertion section 101 inserts padding bits in a transmission bit sequence based on a parity check matrix, and outputs the generated bit sequence to an LDPC encoding section 102. Using the parity check matrix, LDPC encoding section 102 performs LDPC encoding on the bit sequence input from padding bit insertion section 101, and obtains an LDPC codeword composed of systematic bits and parity bits. Then a puncturing section 103 eliminates padding bits from the LDPC codeword input from. LDPC encoding section 102, and also punctures parity bits in the LDPC codeword in order starting from a parity bit corresponding to a variable node for which the total number of connections to padding bits via check nodes is larger.
