A device to facilitate post-operative sternal closure by twisting the opposite end regions of the suture wire together comprises spaced guides in the form of limbs (1 and 2) with passageways (3 and 4) through which the proximal wire ends (12) and (13) may be fed and a cross-piece (7) transversely positioned with respect to said guides whereby, in use, the wire end regions may be bent across and supported by the cross-piece. The cross-piece includes a discontinuity (8) with a spacing adapted to be less than the thickness of wire. As the tension in the wire increases during the course of the twisting motion a point will be reached when the wire end regions forcefully deform the cross-piece (7) enabling the wires to pass through the discontinuity. Thus an indication is given when a maximum tension is reached.

Method and modem for fast timing recovery of transmitted data between a master χDSL modem and a slave χDSL modem, over a noisy, high loss, high distortion wiring. Transmitted QAM symbols are received and sampled at the slave modem. The sampled data is split into in-phase and quadrature channel, each of which is filtered by matched filter. The filtered outputs are sampled at twice the symbol rate and the lower and upper band edge components are extracted by modulating each of the sampled sequences of outputs with two discrete time sequences: cos(0.5 π n)=. . . 1,0,−1,0 . . . and sin(0.5 π n)=. . . 0,1,0,−1 . . . . Each of the resulting products is filtered with a first order low-pass filters and re-sampled again at the symbol rate. The Bit Error Rate is computed, and the slave modem switches from blind timing recovery mode, to data directed timing recovery mode, after the Bit Error Rate has sufficiently decreased.

Such processes as compression, storage and reproduction of an image mapped on a three-dimensional coordinate system such as a spherical surface or a cylindrical surface are performed suitably by mapping omnidirectional map information to a two-dimensional image such that the redundancy may be low while the amounts of information is kept equal as far as possible with minimized errors. Preferably, the image is converted into a two-dimensional image in a form determined taking the performance of the omnidirectional video image reproduction side into consideration. The technique can be utilized when mapping information which describes a corresponding relationship between the three-dimensional coordinate system of the original omnidirectional image and the mapped two-dimensional image coordinate system is produced to synthesize an omnidirectional video image from an arbitrary viewpoint direction.

Methods and systems for a mixed time-frequency domain compander, where the expander and compressor are applied in the frequency domain (subbands), while the limiter and the linear gain are applied in the time-domain (full band). Far-end noise reduction is achieved by adapting the expander gain to the far-end noise, near-end noise compensation is achieved by adapting the linear gain and the compressor gain to the near-end noise. The range of the linear gain section is set individually for each subband, but the linear gain is essentially applied to the full band signal via a scaling procedure. The scaling procedure first reduces the compander gain in the frequency domain by a scaling factor and then performs the reciprocal reverse scaling in the time domain. Far-end noise reduction is coupled to near-end noise compensation in order to avoid cross-modulation of the far-end noise by the near-end noise.
