Patent EP-0264940-A3 (EP)
IPC: B65H3/12
Filed: 1987-10-22
Abstract: In einer Maschine zur Herstellung von zweiteiligen Gegenständen, bei­
spielweise einem Faltschachtelzuschnitt mit einem Fenstereinsatz 
werden die ersten Teile vereinzelt, im wesentlichen senkrecht 
zur Förderrichtung der zweiten Teile,gefördert und dort mit diesen 
verbunden. Durch spezielle Vorrichtungen zur Justierung sowohl 
der ersten (11) Teile als auch der zweiten (10) Teile, kann eine einfache 
Transportvorrichtung Verwendung finden, nämlich Transportschlitten, die 
die gestapelten zweiten (10) Teile aus einem Magazin (31, 32) ergreifen, 
über die ersten Teile fördern und dort lagegerecht absetzen. Beson­
ders wirtschaftlich kann die Maschine arbeiten, wenn beidseitig 
der Fertigungsstraße (20) derartige Magazine vorgesehen sind, die 
synchron alternierend von zwei derartigen Transportschlitten (33, 34) 
angefahren werden, die die jeweiligen zweiten Teile abwechselnd 
auf der Fertigungsstraße bzw. den dort positionsgerecht geförderten 
ersten Teilen absetzen, wo beispielsweise eine Verleimung stattfin­
det. Die Maschine kann sowohl als Einzelmaschine Verwendung finden, 
als auch leicht in eine Fertigungsstraße integriert werden bei 
Produkten, deren Herstellung mehrere Arbeitsgänge erfordert.  
     Grundsätzlich kann die Maschine beliebige erste und zweite Teile 
verarbeiten, bei denen eine exakte relative Positionierung erfor­
derlich ist.

Title: Connection element for light-guides
IPC: G02B6/40
Filed: 1987-12-04
Abstract: A connector element for light waveguides has two carrier members which have guide grooves for the optical fibers and guide channels receiving guide ribs of guide rails for holding the two carrier members in alignment. To prevent possible misalignment due to micro-offsets in the surfaces of the guide channels and ribs of the guide rails or dust particles or the penetration of an immersion material into the guide channel, a portion of the contacting surfaces, either the contacting surface of the guide channel or of the guide rib is removed so that engagement between the rib and channel occurs only at spaced locations.

Title: Computationally efficient technique of image contrast enhancement
IPC: G06T5/00
Filed: 1989-10-24
Abstract: A computationally efficient image contrast 
enhancement technique is disclosed herein. The image 
contrast enhancement technique of the present invention 
is adapted to adjust the intensity of an image of a 
scene, the image being realized from electrical signals 
generated in response to radiation received from a 
plurality of regions within a field of view of the 
scene. The technique of the present invention includes 
the step of filling a first matrix with digital entries 
corresponding to each electrical signal, the difference 
between the maximum and minimum digital entries defining 
a first dynamic range. The first matrix is sampled to 
create a set of digital entries having a second dynamic 
range substantially similar to the first dynamic range. 
A histogram of the set of digital entries is then 
constructed. A first transfer function is generated by 
at least approximating the integral of the histogram, the 
first transfer function having a value at each of the 
digital entries. The technique of the present invention 
further includes the step of generating a second matrix 
having entries obtained by multiplying each of the 
entries of the first matrix by the value of the first 
transfer function at each of the entries. The image of 
the scene is generated by driving a display with signals 
derived from the entries of the second matrix.

Patent EP-0388701-A3 (EP)
Title: Clock recovery circuit
IPC: H04L7/033
Filed: 1990-03-05
Abstract: A clock recovery circuit (20) utilizes a Voltage Controlled 
Oscillator (VCO) (19) having a base frequency which is substantially equal 
to or slightly less than the rate of a data input signal which allows for 
very high frequency systems which require data synchronization. A D 
Flip-Flop (15) provides phase comparison between a recovered clock 
signal and an incoming data signal, and produces an error signal only 
when the data signal leads the recovered clock signal. The error signal 
determines the amount of shift necessary to cause the timing of the 
recovered clock signal to equal that of the data signal. If the recovered 
clock signal leads the data signal, the absence of the error signal will 
cause the recovered clock signal to fall back to its base frequency which is 
guaranteed to be slightly less than the frequency of the data signal. The 
clock recovery circuit is only required to make timing adjustments in 
one direction which greatly simplifies the required circuitry.
