Abstract: A peripheral DMA (direct memory access) system having a computer with an internal DMA controller and only one channel available for external DMA operations includes: a peripheral DMA controller coupled between the computer address bus and a peripheral address bus, and also between the computer data bus and a peripheral data bus. The peripheral DMA controller includes a dual port "frame map memory" in which addresses of various peripheral devices are sequentially stored prior to initiating a DMA operation wherein data is rapidly transferred from various peripheral devices having nonsequential addresses to sequential locations of the computer memory or vice versa.

Abstract: A method for making tuned resonance passive electronic filters. The method consists of computing the values of the filter components and then using standard unmatched components that approximate the computed values in conjunction with certain components that are made variable for the purpose of tuning out the unmatched characteristics of the unmatched components. A typical filter may include several poles where each pole includes an unmatched component, such as a capacitor, and a variable component such as an inductor. Adjacent poles may be coupled by unmatched or variable inductors or capacitors. Each pole is tuned for resonance by applying the output of a signal generator to a particular pole, while shorting adjacent poles, and tuning the variable component of that pole for resonance. Resonance may be indicated by a null on an a.c. voltmeter connected to measure pole.

Abstract: The subject invention is an ECL to CMOS converter for converting high or low ECL logic signals. The converter comprises a CMOS inverter for providing low or high CMOS logic signals at its output in response to a first or second signal, respectively, applied to its input. The first signal must exceed a first predetermined value and the second signal must fall below a second predetermined value. The first and second predetermined values are such that either the low ECL signal does not fall below the second predetermined value or the high ECL signal does not exceed the first predetermined value. The converter also provides means for converting the high and low logic signals to the first and second signals, respectively.

Abstract: An instrument for measuring the resistive and reactive components of eleccal circuits without physical contact or breaking the circuits. The instrument consists of a transmitter, a receiver, a sensor head, a power supply, and a display. The sensor head is constructed of two transformer cores split and hinged so that it can be closed around part of the circuit to be tested. One transformer core is driven by an oscillator and induces ac voltage in the test circuit. Current flow depends upon the electrical characteristics, admittance, of the test circuit. The other transformer core acts as a receiver and its output is an ac voltage proportional to the current flowing in the test circuit. The ac signal is detected using a synchronous detector with reference derived from the transmitter, either in phase to measure the resistive component, or with a 90.degree. phase shift to measure the reactive component.

Abstract: This invention relates to a method and system for remote detection of a targeted substance by the appropriate application of a probing signal that induces molecular resonance in the target substance to create an identifiable signature or response. In the preferred embodiment, signals transmitted are an Infrared laser beam, amplitude modulated in the range of 100 kHz frequency. The probing signal stimulates molecular resonance of the target substance which produces characteristic electron signal responses that are detected by IR detectors. A software program is used to process the electrical response signals and to compare them with electrical response signals stored in a database of known substances, thus allowing the target substance to be identified. The system may also be used to locate targeted substances.

Abstract: A microprocessor controlled micro-stepping chart drive circuit is disclosed. The invention comprises a step clock system, a micro-processor controller and a motor drive circuit. A speed selector establishes a numerical constant within the controller. This numerical constant is decremented down with each pulse of the step clock. When the counter reaches zero, the motor drive circuit is updated. Therefore, the time between updates of the motor drive circuit is a function of the value of the numerical constant.
