Title: Reproducing digital video signals
Inventor: OIKAWA YUKA
IPC: H04N5/783
Filed: 1995-08-22
Abstract: In a method and apparatus for reproducing digital video signals, in which every one frame of data of the signals is recorded on n tracks (A1, B1, ....... A10, B10) of a recording medium by an inclined azimuth recording system, the signals are reproduced at varying speed by a rotary head (1) having n heads (HA1, HB1, HA2, HB2) with a varying playback speed S controlled (7) to be equal to a(t.m+/-1)/n, where a is a constant equal to 1 or 2 and m is a constant which is an integer other than 0. Due to this, when a picture corresponding to the digital video signals read out with the varying playback speed S is displayed on a screen, non-continuous lines caused by a temporal difference between neighboring macro-blocks during varying speed reproduction may be rendered less obtrusive so as thereby to improve the picture quality of the varying speed reproduced picture. <MATH>

Abstract: A process for the mfr. of composite baths consisting of an inner plastic shell, an outer shell and an intermediate filler comprises turning the preformed outer shell over the moulded inner shell of plastic, and injecting filler into the interspace between shells, using the outlet and overflow openings.The fluid plastic is mixed for injection by the injection head of a two-component, high pressure machine. This head is mounted pressure-tight onto the openings. Also claimed is a device to carry out the claimed procedure. Pref. mixing of the components takes place in counterflow, avoiding a separate mixing stage. The pressure before injection is 60-200 bar, pref. 90-150 bar, esp. about 120 bar. A vent in the outer tub vents the interspace, spaced away from and above the injection point. The inserted filler is controlled from the vent or riser, when after an empirically determined interval, it appears there, and supply is terminated. Filler is injected at the drain opening with a formed-in cone, filling from an annular region into the interspace. Compact polyurethane without gas inclusions, or a polymethyl methacrylate is used. The inner shell is plastic, the outer is plastic or steel. Before inverting one shell over the other, spacers are included, which will redirect the injected flow before completing the filling.

Abstract: An adaptive control system and method for
actively canceling tones in an active acoustic
attenuation system has an adaptive parameter bank.
Adaptation of the adaptive parameter bank can be
constrained with respect to the null space of a C model
of an auxiliary path (e.g. speaker-error).
Alternatively, output from the adaptive parameter bank
can be constrained with respect to the effective null
space of the C model. The preferred system uses singular
value decomposition, normalization, and demodulation to
implement the methods of constraining output and
adaptation. The invention can eliminate stability and
tracking problems associated with over-parameterization.
