摘要： Method and arrangement for displaying a digital waveform in an eye diagram simultaneously with an indication of acceptability of the digital waveform. A decoded digital waveform is separated into overlapping waveform permutations based on a number of digital states and transition points in the eye diagram. Submasks equal in number to the waveform permutations and that are derived from a common, known good waveform, are retrieved from a memory component. Each retrieved submask is applied to a corresponding waveform permutation to determine any locations at which the waveform permutation exceeds a boundary of the submask. Only one submask is applied to each waveform permutation. The waveform is displayed in the eye diagram simultaneous with a visual indication of the locations at which any of the waveform permutations exceeds the boundary of the corresponding submask, to enable visual assessment of the acceptability/validity of the digital waveform.

摘要： Method and system that produce requisite drive signals to fully exercise and test electromechanical elements of a liquid rocket stage including solenoid valve drives, DC motor drives and actuator drive signals. The electrical driver tester includes a signal processor, power driver circuits, and A/D and D/A circuits to monitor and control the drive circuitry. Drive current is monitored and a signal proportional to the current is produced for the purpose of analyzing current profiles as part of the test regimen for the device under test. Actuator speed and positioning are controlled in real time with a tailored lead lag control algorithm implemented with digital signal processor hardware.

摘要： Method and sequence for locating anomalous features in medical images in which medical images are supplied by an external source such as a CAT or XRAY scan machine or other similar device. A sequence of specific measurements is executed on the supplied data to obtain metrics relating to the images. The metrics are then compared to the corresponding values in an accompanying database resulting in an anomalous/not anomalous determination. Anomalous determinations are presented to the test operator for final analysis along with supplemental historical data. In application to all types of medical imagery, potential anomalies are quickly located resulting in an efficient and more accurate diagnosis.

摘要： System that focuses electron beams in an electro-static area to a laminar flow of electrons with uniform distribution of current density and extraordinary demagnification includes a housing having a first interior portion and a second interior portion electrically insulated from the first interior portion. The second interior portion has an electric field-free space. An electrode system is disposed in the first interior portion and includes a cathode assembly and at least one anode assembly. The cathode assembly generates an electron beam that passes through each anode assembly and then into the electric field-free space in the second interior portion. A position of a crossover point on a longitudinal axis maybe regulated by varying dimensions of a substantially cylindrical portion of the anode assembly and a substantially cylindrical portion of a near-cathode electrode assembly.

摘要： System that measures absolute or additive phase noise includes a power divider for dividing an input RF signal, a local oscillator, two mixers, each arranged in a path of a respective signal component from the power divider and receiving input from the power divider and local oscillator, two digital radio frequency memories, each associated with a respective mixer and receiving an input signal therefrom, and a digital signal processor that receives signals from the digital radio frequency memories and outputs a digital data stream indicative of measured phase noise. For absolute phase noise measurement, phase noise of the input RF signal is provided. For additive phase noise measurement, a unit under test is arranged in one of the paths between the power divider and the mixer. The system may be interposed between a radar transmitter of a radar environment simulator and a radar receiver coupled to a radar target display.
