Patent EP-0685850-A3 (EP)
IPC: H01L21/8244
Filed: 1995-05-17
Abstract: Each memory (200) cell in an SRAM array contains an auxiliary reading 
(MR1) transistor connected across one of the transistors (MP1) in each cell. A row 
read line (RRi) controls the ON-OFF condition of this auxiliary reading transistor. 
In addition, each cell has two access transistors (MW1,MW2) for connecting the cell 
to complementary column bit lines (Bj, B j). The ON-OFF condition of both of these 
access transistors is controlled by a row write line (RWi). Each cell has two power 
nodes (N3,N4), one connected to a power source such as VDD and the other 
connected to a column detector line (Dj) that terminates in a current sensor. The 
state of the memory cell is sensed by this current sensor. In one embodiment, the 
power line that brings the voltage VDD to the cells is a column line; in another 
embodiment, it is a row line. Thus there are a total of four column lines and two row 
lines in the one embodiment, and a total of three column lines and three row lines in 
the other embodiment.

Abstract: A communication network called a bidirectional mesh network (MSN), also
called bi-MSN, is described. The bi-MSN includes a plurality of first communication
loops (horizontal loops) (204) each comprising a plurality of nodes (208) interconnected to one
another by bidirectional communication links. The bi-MSN also includes a plurality
of second communication loops (vertical loops) (206) each comprising a plurality of nodes
interconnected to one another by bidirectional communication links. Each second
communication loop is connected to each first communication loop at a node which
is common to both the second communication loop and the first communication loop.
This common node (and, in fact, each node in the bi-MSN) includes a switch to
transfer packets from the first communication loop to the second communication loop,
and vice versa, as a function of destination addresses contained in the packets.

Abstract: A bit rate control mechanism for a digital image or video
compression system estimates a complexity parameter for a current
picture, or block of samples, of a video signal as a function of parameters
for a prior picture of the video signal, which parameters include a bit rate.
From the complexity parameter a quality factor for the current picture is
determined and applied to a quantizer to compress the current picture. A
complexity pre-processor may also be used to detect scene changes in the
video signal prior to estimating the complexity parameter. If there is a
scene change detected, then the rate control mechanism is reset prior to
estimating the complexity parameter for the first picture in the new scene.

Abstract: The integrated multimode optical coupling apparatus comprises an N-to-M
optical coupling arrangement that is simple to manufacture, minimizes optical losses
and is significantly less expensive than the prior art arrangements of coupling optical
signals. The preferred embodiment of the apparatus of the present invention
comprises a substrate into which is formed a plurality of optical channels, each of
which is joined at one end into a single output optical channel. This integrated optical
coupler is formed by diffusing silver ions or other equivalent ions into the glass
substrate in these defined areas to form channels of high optical refractive index in the
body of the substrate. At one end of each of the optical channels that are formed in
the substrate, the plurality of the optical channels are joined together in a volumetric
region of the substrate wherein the individual channels merge into one unified
common structure. The output optical channels are joined to this combiner to thereby
carry the combined light output to the output terminals. One application of this
apparatus is in the field of photoplethysmography, such as in a pulse oximeter
instrument.

Abstract: The invention relates to a circuit arrangement for generating two signals having a
phase difference of approximately 90 degrees. The invention is preferably applied
in the demodulator of a radio receiver. In order to shift the phase of a signal one
idea of the invention is to use a distributed resistance/capacitance circuit or a
distributed RC circuit (Z 10 , Z 20 ) in connection with a signal amplifying means (A 1 ,
A 2 ). The operation of the circuit is not frequency dependent and a circuit
adjustment is not necessarily required in order to calibrate the phase difference,
because the distributed RC circuit can provide an substantially constant phase shift
of ±45 degrees over a wide frequency range. The whole circuit can be integrated
into one component, because a distributed RC circuit is easily made on the same
integrated circuit substrate as the amplifying means, and thus the circuits can be
made into a small size and at low manufacturing costs.

Abstract: For audio coding, the MPEG-2 standard provides
for a spatial representation by multi-channel
reproduction. In order to ensure backwards compatibility
with MPEG-1 signals, the signals of the multi-channel
sound channels are matrixed. Before being matrixed, the
audio signals generally have their levels reduced in
order to prevent overdriving. In order to balance again
the reduction at the encoder end, an option that is
provided in the MPEG-2 standard is for a decoder to raise
the output levels again. If, however, a transmission
error then occurs in the multi-channel section, the
decoder cannot carry out the reverse matrixing. In that
case, only the MPEG-1-compatible signal component will be
decoded. The auditory impression can therefore be
disturbed in various ways during the changeover to MPEG-1
decoding. According to the invention, in the event of
errors being detected in the supplementary signals, a
portion of the multi-channel audio signals is cross-faded
to the MPEG-1-compatible signal components and/or a
further portion of the multi-channel audio signals is set
to zero, in which case, at the decoder end, level raising
of the MPEG-1-compatible signal components can be
effected prior to the cross-fading of the multi-channel
audio signals.
