Title: Distributed sensor and method using coherence multiplexing of fiber-optic interferometric sensors
IPC: G01D5/26
Filed: 1986-02-05
Abstract: A distributed sensor system including an optical source (100) having a short coherence length for optionally continuously monitoring each sensor in the system. In one preferred embodiment, an array of fiber-optic sensors (110) are organized in a ladder configuration, with the sensors positioned in spaced relation and defining the rungs of the ladder. Light transmitted through the sensors is multiplexed onto a return arm (114) of the ladder, with sensor spacing being such that interference between light from different sensors is prevented. The multiplexed signals are received by an optical fiber receiver (118, 120) which couples the mutiplexed light with an interfering optical reference signal to produce a phase difference signal representing conditions influencing selected sensors. Embodiments are disclosed for use of either pulsed or continuous wave light sources. In another preferred embodiment, the sensors comprise a plurality of interferometers (404,406) connected in series configuration by a common optical fiber (402), which provides multiplexed output signals from the sensors to another plurality of interferometers (418, 420) comprising receivers. Functional equivalents of the series configuration provide sensors and receivers comprising birefringent or two-mode fiber. The optical path length differences between each pair of sensor arms (409, 410, 411 and 412) are selected to prevent interference between the multiplexed sensor output signals from the various sensors. The optical path lengths through the sensors (404, 406) and receivers (418, 420) are structured so that each receiver (418, 420) produces a phase difference signal relating to conditions affecting light transmission through a specific sensor (404, 406). A phase and amplitude modulation technique is disclosed for providing heterodyned output signals from the dristributed sensor system.

Title: Active filter
IPC: H03H19/00
Filed: 1987-09-04
Abstract: An active filter with switched capacitors for the traffic broadcast signal of a VHF receiver shows an inverting first amplifier and a second amplifier, an analog shift register with at least two register stages and an adder. The shift register is connected to the output of the inverting first amplifier and the adder adds the output signals from the second amplifier and shift register and sends the summation signal to the first amplifier. The switching frequencies of the capacitors and shift register are rated equal to twice the frequency of the filter input signal multiplied by the number of a register stage in the shift register. In a filter of this type used to filter the MPX signal, the critical capacitive ratios are in the order of 1:1, so that, with high precision, only a small area is required for the manufacture of the capacitors using SC-MOS technology. <IMAGE>

Abstract: A transformerless power supply and display energising 
circuit for a clock circuit with a duplex optoelectronic 
display (14) driven by a low voltage integrated clock 
circuit (12) having positive and negative voltage input 
terminals (+V, -V) and the duplex display having a first 
terminal (common 1) connected to a first common cathode and

cathode of the display for energising it. The transformer­
less circuit is powered from an AC source. An impedance 
(21), which may be either resistive or reactive, reduces 
the AC voltage to a level suitable for the integrated clock 
circuit. The transformerless circuit generates synchronous 
DC level-shifted pulse trains for driving the positive 
input terminal of the integrated clock circuit alternately 
between a first voltage and a reference voltage while 
synchronously driving the display first terminal (common 1) 
between said first voltage and a voltage of equal amplitude 
and opposite polarity. The display second terminal (common 
2) is held at the reference voltage.

Title: Method for debulking partially precured thermoplastic composite laminae
IPC: B29C43/56
Filed: 1988-12-05
Abstract: A method for forming a thermoplastic laminate 
having a desired laminate thickness is disclosed. Layers 
of composite material using precured or partially 
precured thermoplastic resin laminate layers are layed-up 
on a forming tool. A relatively constant, uniform 
pressure is applied to the layers to produce a 
preconsolidated laminate having a thickness approximately 
equal to the ultimate desired laminate thickness. The 
laminate layers are free to slide relative to one another 
during debulking because they are either cured or 
partially cured. Thus, wrinkles are avoided. The 
debulked laminae are then consolidated in a conventional 
autoclave under elevated temperature and pressure.
