Title: Digital data multiple conversion system for converting data having a frequency to data having another frequency by a digital stuffing method
IPC: H04J3/07
Filed: 1988-03-16
Abstract: A digital data multiple conversion system includes a memory 
unit (21) storing input data (IN-DATA) having N bits, a 
first frequency divider (23) frequency-dividing an input 
clock (IN-CLK) having a first frequency (f₁) at N to 
output a first frequency-divided signal (S23), a first 
pulse width expansion circuit (25) connected to receive 
 m  frequency divided pulses from the first frequency 
divider, where  m  indicates the number of lost pulses of 
the input clock plus one receiving the input clock, and 
outputting a first pulse width expanded signal (S25) of 
the input clock having an m + 1 pulse width, a 
circuit (22) outputting a read clock having a second 
frequency (f₁′) near to the the first frequency (f₁) and 
stuffing the read clock, a second frequency divider (24) 
frequency-dividing the read clock at N to output a 
second frequency-divided signal (S24), a second pulse 
width expansion circuit connected to receive  n  frequency 
divided pulses from the second frequency divider, where 
n indicates the number of lost pulses of the read clock 
plus one, receiving the read clock, and outputting a 
second width expanded signal of the read clock having an 
n + 1 pulse width; a phase detector (27) outputting a 
phase detection signal (S27) when the phases of both 
pulse width expanded signals coincide, and a stuffing 
request circuit (28) outputting a stuffing request 
signal (S28) to the stuffing circuit (22). 
 
  
     The stuffing circuit (22) stuffs the read clock in 
response to the stuffing request signal (S28). The 
memory unit (21) stores the input data in response to 
the first frequency-divided signal (S23), and outputs 
the stored data to the stuffing circuit (22) in response 
to the second frequency-divided signal (S24).

adjustment act on the two modulators (5, 6) in such 
a manner as to give them nonlinear response curves 
so as to compensate for the nonlinearity of the 
power amplifier placed downstream from the 
linearizer.

Title: Digitizer stylus with pressure transducer
IPC: G06F3/033
Filed: 1988-03-15
Abstract: A stylus switch is activated automatically when the tip of 
the stylus is pressed against a digitizer tablet with sufficient 
force. The pressure switch includes a transducer in the form of 
an ink layer having electrical resistance which varies as a 
function of the pressure applied thereon. Electrodes of 
conductive ink contact the ink layer of the transducer, providing 
a circuit element including a variable resistance. The current 
which flows between the two conductive ink electrodes varies as a 
function of the force with which the stylus tip is pressed 
against the data tablet, thus providing an analog output which 
can be detected as a function of pressure or which can be 
detected to determine when the pressing force exceeds a 
predetermined value. Processing of the data representing the 
coordinates of the stylus tip is enabled only when the tip is 
being pressed with at least a predetermined force, i.e. the 
amount of force applied by a stylus user during writing. The ink 
layers of the electrodes and transducer, as well as the stylus 
anode, are applied on a single piece of flexible plastic film 
which is wrapped around a central assembly and inside a coaxial 
barrel. A collapsible dome of metal is arranged to provide 
tactile feedback to the user when the predetermined force is 
obtained.

Title: Method of and device for generating and reproducing two-dimensional graphical objects
IPC: B41B19/00
Filed: 1988-04-22
Abstract: A method and a device for generating and for reproducing two- dimensional graphic objects for electronic or electromechanical reproduction using polynomials is proposed, the graphic objects being given as reference contours in contour coordinates and the number of contours per object and the number of contour parts per contour being determined and the starting point and end point of the contour parts being ascertained. For the purpose of generation, the length of each given contour part is divided up into a multiplicity of arc segment lengths. The starting point and end point of the given contour part are connected by a defined curve portion, preferably a straight line, whose length is divided up into the same number of arc segment lengths as the given contour part. The coordinate points of the straight line assigned to the respective arc segment lengths and of the given contour part are compared and the distance between them ascertained. If a given distance is exceeded, that coordinate point on the given contour part is selected which is at the greatest distance from the straight line. Using parametric splines a curve is determined between the starting point and end point and the point selected as a point of support of motion. 
<??>The length of the curve is again divided up into the same number of arc segment lengths as the given contour part and the same process is repeated. When the given distance is no longer exceeded the points of support motion are stored.

Abstract: Es wird ein Spinnverfahren, wie Offenend-Spin­

material enthalten sind, grösstenteils in das Innere 
des Garns zu liegen kommen. Trotzdem wird das Stapel­
fasermaterial vor dem Spinnen einer Kämmung unterwor­

Die Stapelfasern werden in Form einer Watte (W) einem 
Zangenaggregat (11, 13) zugeführt, das jeweils einen 
Faserbart zunächst einem rotierenden Rundkamm (18, 19) 
vorhält. Danach wird das Zangenaggregat (11, 13) vorge­
schoben und gibt den ausgekämmten Faserbart direkt, ohne 
Berührung mit weiteren Kammelementen, in die Klemmstel­
le von Abreisszylindern (6). Das Weglassen des sonst 
stets verwendeten Fixkammes vor den Abreisszylindern 
ermöglicht ein höheres Gewicht der Watte (W) und damit 
eine erhöhte Produktion der Kämmvorrichtung. Damit kann 
in wirtschaftlicher Weise eine Verbesserung des Garns 
erzielt werden.

Title: Real-time network routing
IPC: H04M7/06
Filed: 1989-12-14
Abstract: An arrangement for routing calls from a source switch (NSN 3) to a 
destination switch (NSN 8) in a telecommunications network. If a direct 
trunk is available between the two switches, that trunk is used. 
Otherwise, the destination switch is queried to obtain availability 
data of trunks to that switch from intermediate switches (NSN 4, 7) of 
the network. This availability data is then compared with availability 
data of trunks from the source switch to the intermediate switches. A 
route is then selected using an intermediate switch having available 
trunks from the source switch and to the destination switch. If a route 
using lightly loaded trunk groups (LL) is available, that route is 
selected in preference to the use of a route using more heavily loaded 
trunk groups (HL). Advantageously, routing is performed to dynamically 
optimize selection of a route based on the current state of the network.
