摘要： A system and method for processing of audio and speech signals is disclosed, which provide compatibility over a range of communication devices operating at different sampling frequencies and/or bit rates. The analyzer of the system divides the input signal in different portions, at least one of which carries information sufficient to provide intelligible reconstruction of the input signal. The analyzer also encodes separate information about other portions of the signal in an embedded manner, so that a smooth transition can be achieved from low bit-rate to high bit-rate applications. Accordingly, communication devices operating at different sampling rates and/or bit-rates can extract corresponding information from the output bit stream of the analyzer. In the present invention embedded information generally relates to separate parameters of the input signal, or to additional resolution in the transmission of original signal parameters. Non-linear techniques for enhancing the overall performance of the system are also disclosed. Also disclosed is a novel method of improving the quantization of signal parameters. In a specific embodiment the input signal is processed in two or more modes dependent on the state of the signal in a frame. When the signal is determined to be in a transition state, the encoder provides phase information about N sinusoids, which the decoder end uses to improve the quality of the output signal at low bit rates.

摘要： A multiple contact connector has an elongate actuating member which is reciprocally mounted in a housing holding the contacts, the contacts in one or more linear arrays. On longitudinal reciprocation of the actuating membert it is also caused to reciprocate up and down in a direction normal to the longitudinal direction. In so doing it pushes on the contacts, deflecting them sideways. The connector is then assembled or inserted, after which the actuating member is moved to release the contacts. A substantially zero insertion force is obtained.

摘要： A self-shearing connector for electrical conductors comprises a helical spring of rectangular cross-section wire around a central member extending from a body member. The spring has an upper or end turn with an end part of an external diameter smaller than the inner diameter of the next or lower turn. On compression of the spring the end part of the upper or end turn is pushed down into the next turn shearing off the end of the conductor. The conductor is gripped between the lower turn and the body or between the spring turns. If the conductor is insulated, the gripping pressure splits the insulation at opposite sides of the conductor to provide electrical contact.
