Patent EP-0381385-A2 (EP)
Inventor: AGGERS JOHN R
IPC: H04L12/403
Filed: 1990-01-26
Abstract: A communications system has an active master node (10) which transmits request messages in serial bit fashion on a data bus (39), and a plurality of responder nodes (40,41) each of which receives the request messages on the data bus (39) and may respond to a request message with a serial bit answer message. The possibility exists that a plurality of responder nodes (40,41) may provide concurrent answer messages forming a composite signal which the active master node (10) may not be able to recognize as containing answer messages. A low pass filter (25,28) is provided in the active master node (10) which provides as its output only those pulses in the composite signal whose length is within a predetermined interval, typically from approximately a tenth to one half of the interval for each bit in the answer messages. A counter (29) receives the low pass filter output and provides a collision signal (Q₂) to the associated master node (10) if more than a preselected number of pulses within the predetermined interval are present. By providing the collision signal only after detecting a plurality of these pulses in the low pass filter (25,28) output, it is possible to avoid false detection of concurrent answer messages whose presence is simulated by noise on the line.

Title: Tone spacing and power level monitoring for FSK lightwave systems
Inventor: TZENG LIANG D
IPC: H04B10/14
Filed: 1990-11-23
Abstract: Apparatus and method are disclosed for controlling the tone spacing (2ω d ) and output power level in an FSK lightwave transmitter (12). An arrangement (22) is utilized which splits a tapped-off portion S(t) of the output data stream X(t) into two essentially equal components (S₁,S₂). A first component (S₁) is then delayed and scrambled (polarization state) (by 24,28,29) with respect to the second component (S₂). Self-heterodyning of the two signals results in forming a signal V(t) at the beat frequency, or tone spacing value. By comparing this beat frequency with a predetermined tone spacing value, ω ts , adjustments may be made to the transmitter to maintain the desired tone spacing value. The self-heterodyned signal will also contain a component indicative of the data signal power level and may be utilized to adjust the transmitting device so as to maintain a constant power.

Abstract: A superconductive transmission line (20) is formed of mixed metallic oxide ceramic material, particularly Y₁Ba₂Cu₃O 7-x  drawn epitaxially upon a substrate (76). The superconductive material has basal crystallographic planes (44) in alignment with copper oxide of the ceramic material. The planes (44) are parallel to the substrate (72). The transmission line (20) is constructed of a plurality of electrically conductive elements (38, 40, 56, 60), each of which is formed of the superconductive material. The conductive elements (38, 40, 56, 60) are arranged with the basal crystalline planes (44) parallel to an axis (46, 72) of the transmission line, along which axis power is to flow. Thereby, magnetic fields (48) induced by currents flowing in the conductive elements (38, 40, 56, 60) intersect the conductive elements (38, 40, 56, 60) perpendicularly to the basal crystallographic planes (44) to maximize the current which can flow while retaining linearity between magnetization and applied magnetic field. Thereby, alternating current can be transmitted by the transmission line without the introduction of hysteresis losses which would develop heat and quench the superconducting characteristic of the transmission line (20).

Abstract: A rear wheel steering mechanism capable of independently positioning the rear wheels (28,30) of a vehicle (10) also independently corrects the toe error of each steered wheel. In the preferred embodiment, each rear wheel is steered by a separate actuator (36,38). The overall steering command for the actuators is determined at least in relation to the front steering angle, the command being constrained within predefined command limits. The actuators, on the other hand, have a control range which exceeds that of the predefined command limits. The controller (52) which generates the steering commands is adapted to receive and store signals representing the toe error of each rear wheel from a conventional wheel alignment machine (66), and the controller causes the actuator to position each rear wheel as a combined function of the steering command and the respective stored toe error signals. When realignment becomes necessary, an alignment machine is connected to the controller, and the apparatus enters a reset mode in which the rear wheels are steered to a "straight ahead" position independent of the previously stored toe error values, and the newly measured toe error values are stored for future steering control.

Abstract: An offset reducer includes an adder for adding an input signal and an offset cancel signal to reduce an offset component of the input signal. A converter serves to measure a difference between a sum of past periods during which an output signal of the adder was positive and a sum of past periods during which the output signal of the adder was negative. The converter outputs an offset detection signal of a given value which depends on a sign of the measured difference when an absolute value of the measured difference exceeds a given difference. The converter initializes the measured difference to a given initial difference when the offset detection signal is outputted. An integrator serves to accumulate the offset detection signal outputted from the converter. The integrator generates the offset cancel signal in accordance with a result of the accumulating the offset detection signal. The output signal of the adder constitutes an offset-free signal corresponding to the input signal.

Abstract: The invention relates to a method and an apparatus for testing of a material (M), especially of melt granules from a waste treatment plant. In the process, the material (M) is introduced into a liquid (F) and its resistance to leaching is tested. After the material (M) has been introduced into the liquid (F), it is provided that at least one variable of state is changed continuously, discontinuously or periodically, and that, in doing so, the course of the same or a different variable of state is recorded as the test course. Prior to this, under the same conditions but without the material (M) a calibration course is determined. The difference of test course and calibration course is then a measure for the resistance of the material (M) to leaching. The method employs a container (1) for liquid (F) and material (M) with a port for feeding in at least one reagent (R), by means of which at least one variable of state of the liquid (F) is changed. Assigned to the container (1) there is at least one measuring instrument (7) for measuring the test course and calibration course. The measuring instrument (7) is connected to an analysis unit (11). <IMAGE>
