Title: Front end circuit structure for a subscriber line circuit interface
IPC: H04M19/00
Filed: 1985-10-14
Abstract: A front end circuit structure for a subscriber line circuit interface employs a controllable amplifier including a switching converter. The switching converter includes a capacitor coupled across a two-wire subscriber line and supplies an auxiliary voltage to the line. The amplifier includes an input adder having an output coupled to the switching converter for controlling the magnitude of the auxiliary voltage with one input of the adder adapted to receive a feedback control signal which is developed by monitoring the voltage across the output. Another input to the adder receives line input signals for the line circuit. The amplifier is controlled in operation by an off hook detector which provides an output signal when the subscriber lines goes off hook to cause the amplifier to operate and further includes ring control logic which is also coupled to the amplifier and activates the amplifier during the presence of a ring control signal. In this manner, the amplifier is operative only during an off hook condition of the line and during ringing generation. The amplifier, based on its structure in the line circuit, provides all basic line functions such as DC current, ringing, voice and remote metering signals.

Patent EP-0198632-A3 (EP)
IPC: H05B41/298
Filed: 1986-04-03
Abstract: An electronic ballast for a discharge lamp has a transistor-­
oscillator arrangement comprising a single transistor (TS), 
whose base is coupled to be driven via a feedback winding (L4) 
of a transformer (TR1). A primary winding (L3) of the trans­
former forms part of a resonant circuit connected in the collec­
tor path of the transistor. A secondary winding (L5) of the 
transformer is connected across a discharge lamp (1) for the 
supply of high frequency alternating voltage to the lamp.  
     The transistor is biased into class A operation, by a biasing 
means (R2, R3). This biasing means can also be used as a dim­
mer by adjusting the operation of the transistor along its 
characteristic curve to alter the collector voltage.  
     The ballast has lamp connector terminals, 4, 5 a first one 
4 of the terminals being connected to an a.c. voltage supply (L), 
and the second of the connector terminals (5) being connected 
to a rectifying means (D1-D4). This ensures that the ballast 
only operates when an operative filament (2) is connected be­
tween the lamp connector terminal (4, 5).  
     Mains supply voltage is filtered by a line filter L1, I2, 
C1-C3.

Patent EP-0265100-A3 (EP)
IPC: C12N5/14

Abstract: Generation of competent  Cucumis  sp. embryoids, plantlets and 
plants (including seeds) from protoplasts, e.g., from 
cotyledonary , root, leaf or stem tissue, by isolation in enzyme 
solution followed by cell wall formation, formation of 
multicellular colonies, formation of minicalli with induction of 
embryoids, plating of minicalli with maturation of embryoids, and 
plantlet development from the embryoids in a series of media, 
CPM-1, -2 and -3, and CTM-4, containing two or more of NAA, ZR, 
2,4-D, BAP and GA₃ under defined temperature, time and light 
conditions. Serial transfer to novel enzyme and  Cucumis  
protoplast induction and expression media for defined periods 
results in cell wall formation, cell division, competent 
minicalli formation, and induction and expression (maturation) of 
competent embryoids and plantlets. Transfer to hormone-free 
development media permits plantlet development, which in turn 
progress to mature normal, flowering, fruiting plants. The 
process is applicable to producing encapsulated embryoids from 
single genotypes or from somatic hybrids as "artificial seeds". 
The process applied to increase of F-1 hybrids permits production 
of "artificial seeds" (encapsulations) in 1/2 to 1/10 the time it 
would take to produce natural hybrid seeds. Techniques involving 
p x /c y  somatic hybridization, freeze storage, and post-thawing 
development are disclosed. Sexual sterility barriers between 
plants in the genus  Cucumis  preventing genetic transfer of 
important characteristics are overcome.

Abstract: A system for in-circuit testing of an 
electronic circuit device utilizes a distributed 
processing architecture wherein separate controllers 
are used to control the testing and for data collection 
and correlation of the collected data to the testing 
conditions. In a preferred embodiment, the testing is 
conducted by sending test vector addresses from the 
test controller to each of the driver/sensor boards in 
the testor electronics, which addresses, in turn, are 
used to access driver memories containing the test 
conditions corresponding to the test vector addresses. 
In the method of the present invention, the circuit 
containing the device is powered up and a tester 
coupling mechanism is connected to the terminals of the 
device. Determinations are made of the physical 
orientation of the device with respect to the tester 
coupling mechanism, and of whether the device terminals 
are in electrical contact with the tester mechanism and 
with the other components of the circuit. Functional 
testing is then performed, and failure data resulting 
from the test are stored and correlated to the test 
conditions which were applied during the functional 
testing.
