IPC: H04N19/423
Filed: 1997-09-11
Abstract: An apparatus for decoding compressed image data
which is variable length coded. In the apparatus, just
a single segment memory (100) is used. An input data
processor (10) counts the effective AC data and
generates an address of where to write the AC data. An
MR/VR flag write processor (12) counts all the MR/VR
flags existing in one segment synchronous section stored
in the segment memory (100) and generates an address of
where to write MR/VR flags existing in the respective
DCT blocks. An MR/VR flag memory (112) stores the
address of where to write the MR/VR flag generated in
the MR/VR flag write processor (12). An MR/VR flag read
address generator (116) generates the address of from
where to read the MR/VR flag stored in the MR/VR flag
memory (112). An AC data read address generator (14)
generates the address of from where to read the AC data
stored in the segment memory (100) with reference to a
start absolute address. A run/amplitude buffer (16)
latches the run/amplitude data read from the segment
memory (100). An address reducer (118) clears the
latched run and amplitude data before the data of the
next area is read, and reduces the address increased due
to the run and amplitude in the case where the run does
not exist and only amplitude data exists in the data
read from the segment memory (100). A DCT block counter
(124) counts the DCT blocks in order to find in which
DCT block the MR/VR data latched in the run/amplitude
buffer exist. A zero flag processor (18) controls a
process of filling the data before the next DCT block to
be latched. A run length decoder (130) run length
decodes the data latched in the run/amplitude buffer.

Abstract: An apparatus and method for coding and decoding
digital video images, capable of maintaining the quality
of static regions, such as background images, in decoded
pictures even when the resolution of pictures has been
changed from high to low. The apparatus is equipped with
two storage units, low-resolution and high-resolution
picture storage units (4,3), to hold reference pictures in two
different picture formats. When processing coded blocks
(or blocks having at least one non-zero transform
coefficient), a high-resolution picture updating unit
(13)converts corresponding blocks of a low-resolution
reference picture retrieved from the low-resolution
picture storage unit (4) to obtain high-resolution block
images. It then updates a high-resolution picture stored
in the high-resolution picture storage unit (3) with the
obtained high-resolution block images. This updating
operation is not applied on non-coded blocks. As a result,
only active regions corresponding to the coded blocks are
updated within the picture stored in the high-resolution
picture storage unit (3), while the remaining part, which may
possibly be static background images, is preserved without
losing their high visual quality.

Abstract: One requirement imposed on a patient table is that it may occupy only a small floor surface area. Therefore, a patient table comprising a compact base is required. For a variety of applications, moreover, it is desired that the table is also constructed to be very rigid in the direction of adjustment of its height. To this end, the height adjustment system supporting the table according to the invention is provided with a drive mechanism which consists of two mutually parallel threaded spindles (54, 56) which pass through an associated nut (50, 52) and expand in two mutually opposed directions. The two threaded spindles are preferably driven by a single motor (70). In order to achieve adequate rigidity in the horizontal direction, the hinge is constructed so as to comprise two arms (28, 30) only.

error signal is higher than the predetermined reference level.

second time out signals. The second predetermined time
period is greater than the first predetermined time period.
A jump pulse producing circuit produces a kick pulse of a jump
pulse signal in response to the jump command signal and holds
the kick pulse regardless of the zero cross detecting signal
until the jump pulse producing circuit is supplied with the
first time out signal when the jump pulse producing circuit is
not supplied with the comparison signal. The jump pulse

Abstract: A light source for generating many precisely spaced wavelength channels, based on the
periodic modulation of light. CW light is periodically amplitude modulated and then coupled to
a non-linear fiber where it undergoes additional modulation by the process of self-phase
modulation or other non-linear effects. In a general embodiment of the multi-wavelength
source (MWS), an optical modulator driven by a periodic electromagnetic signal imposes
periodic amplitude modulation on light from a single longitudinal mode CW laser. The light is
then coupled to a non-linear medium with an intensity dependent refractive index where it
generates higher order spectral sidebands by the process of self-phase modulation and/or other
non-linear effects. The frequency spacing between the spectral components is equal to the
repetition rate of the modulation. The shape of the spectrum (i.e. the relative amplitudes of the
spectral components) can be modified by adjustments to: the amplitude modulated waveform;
the optical power of the waveform. when coupled to the non-linear medium; and/or
characteristics of the non-linear medium such as the non-linear refractive index, the length and
the dispersion.

Abstract: A process for fabricating metal plugs, such as
aluminum plugs, in a semiconductor workpiece. The
invention is suitable for filing narrow, high aspect
ratio holes, and the invention minimizes the formation
of TiAl 3  or other products of interdiffusion between
the plug and the wetting layer. First, an optional
barrier layer is created by covering the bottom of a
hole with a film containing titanium nitride doped
with silicon. Second, a wetting layer is created by
covering the side walls of a hole with a film
containing titanium doped with silicon, in a Ti:Si
molar ratio greater than 1:2. Preferably, the wetting
layer is created by sputter deposition using a
titanium sputtering target containing 0.1% to 20% wt
silicon, most preferably 5% to 10% wt silicon. Third,
the hole is filed by depositing a material consisting
primarily of aluminum. The hole preferably is filled
by sputter deposition using an aluminum sputtering
target, optionally containing dopants such as copper.
To facilitate filling the hole without voids, the
aluminum sputter deposition preferably is performed
"warm", i.e., with the workpiece at a temperature
below the melting point of aluminum but high enough to
promote reflow of the deposited material. The silicon
atoms in the wetting layer inhibit the titanium from
reacting with the aluminum, and the wetting layer
facilitates filling the hole with the aluminum
material without leaving unfilled voids.
