IPC: H03K4/08
Filed: 1986-06-09
Abstract: A constant current source is coupled to first sides of a 
parallel arrangement of binary weighted capacitors. The re­
maining sides of the capacitors are coupled in parallel to a 
digital register circuit such as a flip flop. The rate of change of 
the voltage output signal from the circuit is linear and the 
slope is determined by the selection of capacitors made in 
response to the data stored in the register. Similarly, a circuit 
is constructed in which a time delay or RC time constant is 
generated which is linearly related to the binary value of the 
data stored in the register by replacing the constant current 
source with a resistance circuit.

Abstract: A sleeve for enclosing a cable connection, 
comprising a bendable sheet adapted to be laid around the 
cable connection. The sheet has a series of equally spaced 
longitudinal cuts in at least one marginal portion to be 
arranged transversely of the longitudinal direction of the 
cable connection. The cuts subdivide the marginal portion 
into tongues so that as the sheet is laid around the cable 
connection, the tongues can be laid with a partial overlap 
tapering down onto the cable sheath at the end of the cable 
connection. The longitudinal cuts are formed by cutting 
lines which extend in a direction deviating from the 
longitudinal direction so that the free ends of the tongues 
are offset with respect to the base portions of the tongues 
in a direction transversely of the longitudinal direction.

Title: Audio signal transmission method
IPC: G10L19/00
Filed: 1988-01-30
Abstract: The invention relates to the digital transmission of an audio signal. To save transmission and/or storage capacity, the digital signal is converted into a signal representing the short-time spectrum before the transmission and components of this signal are processed on the basis of psycho-acoustic rules, components of this signal below predetermined thresholds not being taken into consideration. 
<??>It has been found that the general not taking into consideration can lead to reductions in quality in particular signals. 
<??>The invention provides a remedy for this in that at least a first threshold is defined below which only amplitude values outside of psycho-acoustically distinguishable frequency ranges are not taken into consideration.

Patent EP-0279584-A3 (EP)
IPC: G01R33/56
Filed: 1988-02-10
Abstract: The invention relates to magnetic resonance imaging 
methods and apparatus wherein each view of the magnetic 
resonance image is phase encoded with one of a plurality of 
phase encode gradients which vary from each other by a 
multiple of a phase encode gradient interval or step so that 
for a given field of view, the resolution is determined by 
the upper and lower limit phase encode gradient angles, the 
larger the limit angle, the finer the resolution. In such 
a system, when the imaged subject is shorter in dimension 
along the phase encode axis than the dimension of the field 
of view of the image along the phase encode axis, a portion 
of dead space other than the subject is imaged. In 
accordance with the invention to shorten the imaging time, 
the number of views is reduced in accordance with the ratio 
of the subject dimension to the field of view. The size of 
the phase encode gradient steps of intervals is increased by 
the same ratio such that a reduced number of views spans the 
same upper and lower phase encode gradient angle limits. 
This stretches the resultant image. When a generated image 
representation in an image memory is displayed, an inverse 
zoom reduces the dimension of the resultant display by the 
inverse of the ratio such that the a man readable display is 
returned to the proper scale. Along a frequency encode axis 
which is transverse to the phase encode axis, a bandwidth of 
frequencies corresponding to extremes of a projection of the 
subject are determined. Received resonance signals are 
filtered to remove frequency components which are outside of 
the determined bandwidth.
