Abstract: A technique for determining the constellation size of a QAM signal received by a QAM receiver. In general, the implementation of my technique has, as an input signal, a QAM signal having one of a plurality of constellation sizes and determines of constellation size, e.g., 4, 16, 32-ary, by analyzing the probability density function (pdf) of the QAM signal over a pre-established time period. To properly analyze the QAM signal, the signal is first squared and then normalized to a preset value, e.g., 2.0. As such, the signal power in any of the various constellations is normalized to a fixed level. By generating a histogram of the squared and normalized QAM signal, the technique determines the number of levels of modulation contained in the QAM signal. Each constellation size has a unique number of modulation levels and thus forms unique histogram. From the histogram, a particular constellation size can be determined. Thus, by generating a histogram, the technique determines the constellation size of a QAM signal without requiring a priori carrier lock before accomplishing such a determination.

Abstract: To produce an automatic triggering circuit, a current mirror is made up, in the branches of which cells are placed in cascade, equipped with a floating-gate detection transistor. The floating gates of these transistors are charged in different ways, so that the circuit reacts as a function of the value of the difference in these charges. It is then shown that this reaction is independent, on the one hand of the process for fabricating the integrated circuit, and on the other hand on the operating conditions in terms of temperature or power supply voltage. This device is more particularly applicable to the field of chip cards. <IMAGE>

Title: Envelope stuffing machine
Inventor: LONG JOHN D
IPC: B43M3/04
Filed: 1994-05-20
Abstract: An on-the-fly envelope stuffing apparatus (10) has an envelope feeder comprising a pair of parallel feed belts (50a, 50b) for underlying the back panel (51) of the envelope (14) and a laterally aligned medial feed belt (52) for overlying the front panel (54) of the envelope. The medial feed belt descends below the level of the parallel feed belts in the downstream direction. An envelope fed lengthwise through the belts is bent so that the envelope flap (53) is partially opened. This allows interposition of a flap guide (53) to fully open the envelope. The envelope feeder dispenses the envelopes serially to an envelope conveyor (15). An endless tray conveyor (72, 74) parallels the envelope conveyor. Each tray (70) supports an insert stack (12) against which arms (84a, 84b) on the tray rest. As the trays move downstream in synchronism with envelopes on the envelope conveyor, each tray is cammed toward an envelope so that the arms enter the opening of the envelope. A pusher (76) on the tray then pushes the inserts toward the envelope which also cams the arms so that they move toward the side edges of the envelope and are raised to open the envelope to facilitate insertion of the inserts.

Abstract: A communications system includes a receiver and a transmitter for transmitting a communications signal to the receiver. The transmitter adjusts its transmission power level in response to receiver power control signals transmitted by the receiver. The receiver includes an attenuator for attenuating the received communications signal, and measurement circuitry for measuring the signal strength of the attenuated signal. The measured signal strength is coupled to an attenuator controller and to a transmission power controller. The attenuator controller and the transmission controller adjust, respectively, receiver attenuation and transmitter power level so as to optimize system performance. This may include keeping the attenuated signal within the dynamic range of the receiver. This may also include eliminating disturbance signals by adjusting receiver attenuation to produce an effective dynamic range for receiving only signals having a signal strength level that is higher than the disturbance signal strength level, while at the same time increasing the transmission power level to keep it within the effective dynamic range of the receiver. The disturbance signal may be detected as an increased bit error rate of the received communication signal. The apparatus and method may also be applied to systems in which a plurality of receivers are coupled to a common antenna through a receiver multicoupler.
