Abstract: An adjustable output level transmitter (10) includes a direct current energy source, an L-C tank circuit and a switching means for sequentially coupling the capacitors of the tank circuit to the direct current energy source and ground. The output signal frequency is equal to the resonant frequency of the L-C tank circuit and the output signal level is a function of which capacitors of the L-C tank circuit are sequentially coupled to the energy source. The circuit functions in a Class D mode with the inherent advantages of minimal power loss and very high efficiency. Due to the manner of switching utilized, the output signal frequency is very stable and unaffected by the mode of capacitor switching.

Abstract: State of the art (not public): In order to load an ATM switching network as evenly as possible (even in the short term) and thereby minimise cost, the consecutive cells of one and the same connection are switched through to the exit via as many different paths as possible. 
<??>Technical problem: Reciprocal overtaking of consecutive cells must be avoided or corrected. 
<??>Fundamental principle: Each cell is held at the output until it is ensured that no preceding cell can still be temporarily stored in the switching network. Before the cell is forwarded, a check is carried out to ascertain whether, among the cells leaving the switching network at a later stage, a preceding cell is still present which is to be forwarded before it. 
<??>Implementation: Sequence numbers are assigned to the cells on the input side (either on an individual connection basis or not). On the output side, a buffer memory (1) is provided which is operated at least partially (1, ..., d) in the manner of a shift register and thereby produces a predefined delay. Before the output of a cell, at least the part of the buffer memory which is operated in the manner of a shift register is interrogated to ascertain whether a cell registered at a later stage is to be output earlier. If it is, the two cells are exchanged.

Abstract: A power supply control circuit which enables the constant current (CC) and constant voltage (CV) feedback loops to be compensated independent of each other. In accordance with the invention, an inner feedback loop (202) has been added which is local to the output stage (108) so as to allow a constant voltage (CV) feedback loop (112-120) to see a closed loop transfer function of the inner feedback loop (202) that mimics an output for a constant voltage (CV) preferred output stage even though a constant current (CC) preferred output stage is used. As a result, load impedance (118) variations that would have affected the loop gain of the constant voltage (CV) feedback loop (112-120) affect the loop gain of the inner feedback loop (202) only. The inner feedback loop (202) is disposed such that it is automatically disabled by the constant current (CC) feedback loop (102-110) when the power supply enters the constant current (CC) mode and hence allows the constant current (CC) and constant voltage (CV) modes to be decoupled from one another. The inner feedback loop (202) of the invention may also be disposed within the constant current (CC) feedback loop so as to allow independent mode operation for a constant voltage (CV) preferred output stage (108).

Abstract: This invention relates generally to the field of circuits for controlling the beam currents conducted in cathode ray tubes in television receivers, with important use for preventing warping or blistering of the shadow mask used in conjunction with cathode ray tubes for color television receivers, due to heating from localized and intense peak beam currents. 
     An anti-blister circuit comprises a first detector (Q1,R1,R2,R3) for detecting amplitude excursions of a signal with luminance information beyond a white level threshold during each horizontal scan. This enables the circuit to be more sensitive by responding to excursions occurring during each horizontal scanning line. A first timer (C1,R5), responsive to the first detector, provides a first control signal related to a minimum duration of each amplitude excursion of the signal beyond the threshold. This enables the circuit to avoid controlling beam current, for example by reducing contrast, responsive to signal peaks which are too short to cause blistering or warping. Finally, a switch (Q2) and second timer (C2,R6), responsive to the first control signal, provide a second control signal which falls at a first rate to reduce beam current, for example by reducing contrast, during each minimum duration amplitude excursion; and, which rises at a second rate to permit the beam current to increase after termination of the amplitude excursion, until the next minimum duration excursion. The time constant for the second rate is much greater than the time constant of the first rate.
