Title: Device for the processing of two videosignals
IPC: H04N5/91
Filed: 1990-09-21
Abstract: Devices for processing two video signals are used in, among other things, productions in television studios, for titling in camcorder recordings, for superimposition of foreground and background scenes in video plays and so forth. It has been found in practice that it is frequently difficult to design a title before the actual recording. To utilise the possibilities for artistically designing productions, the device consists of a camcorder and a video recorder connected to it via at least two cables. After a switch arranged at the camcorder has been manually operated, a processing of the video signals supplied via the two cables is carried out in the video recorder. The device according to the invention is particularly suitable for subsequent titling of camcorder recordings. <IMAGE>

Title: Method and system for automatic non-disruptive problem determination and recovery of communication link problems
IPC: H04L69/40
Filed: 1990-05-29
Abstract: In the method for problem determination and recovery 
of a failing resource on a communication link segment in a 
data communication network. The using node (6) passes link 
event data to the communication link manager (2) for 
analysis when a problem occurs on a link segment. The 
communication link manager (2) interacts with a configura­
tion data base (4) to determine the physical configuration 
of the failing link segment and the controlling link 
connection subsystem manager (3). The communication link

system manager (3) to initiate tests of the various link 
connection components on the link segment under its con­
trol. When the failing resource is identified, the commu­
nication link manager (2) initiates the appropriate non-­
disruptive recovery procedure through the link connection 
subsystem manager (3) and prompts the data link control to 
restart the line.

Title: Apparatus for continuous control of electric devices according to the phase chopping principle, especially light dimmer, and the use of such apparatus
IPC: H02M5/257
Filed: 1991-03-26
Abstract: An apparatus for stepless control of electric loads by the phase-angle principle includes a semiconductor switch element with main electrodes. A trigger circuit furnishes turn-on pulses for triggering the switch element and includes a detector for the polarity of an instantaneous value of an alternating voltage to be switched, a turn-on pulse pregenerator circuit for furnishing turn-on pulse suggestions, a switch and driver unit, and a decision stage. The decision stage may allow or prevent the turn-on pulse suggestions to be switched through to the switch element, as a function of whether an output signal of the detector has changed its polarity between two of the turn-on pulse suggestions. The decision stage may furnish a blocking signal at least at one input for preventing the turn-on pulse suggestions from being switched through to the switch element, upon the appearance of two turn-on pulse suggestions within one half-wave of the alternating voltage to be switched and in the absence of a turn-on pulse suggestion during one entire half-wave of the alternating voltage to be switched. For brightness control, a transformer has a secondary winding connected to an incandescent bulb and a primary winding connected to one pole of an alternating voltage source and to one main electrode, while another pole of the voltage source is connected to another main electrode.

Title: Circuit for reducing distortion produced by an r.f. power amplifier
IPC: H03C1/06
Filed: 1991-02-04
Abstract: A high frequency SSB radio transmitter has an envelope amplitude modulator 3 for varying the envelope of an r.f. signal source based on an error signal from envelope detectors 5, 6 detecting the envelope of the input and output waveform. It also has a phase modulator 4 for varying the phase of the input waveform based on differences detected in phase detector 10 between the instantaneous phase of the input and output r.f. signal. A signal derived from the error signal controls an amplitude modulator 10 in a subsidiary feedback loop to maintain the size of the envelopes detected by detectors 5 and 6 the same, in order that difference amplifier 7 may operate effectively. Rapid discrepancies between the detected envelopes 5 and 6 occurring within an envelope can then be corrected by amplitude modulator 3. <IMAGE>
