Utilizing round optical fibers as communication channels in optical communication networks presents the problem of obtaining a high efficiency coupling between the optical fiber and the laser. A laser is made an integral part of the optical fiber channel by either diffusing active material into the optical fiber or surrounding the optical fiber with the active material. Oscillation within the active medium to produce lasing action is established by grating the optical fiber so that distributed f...

A processor including a plurality of synchronized subprocessors, each implemented on an integrated circuit substrate and each having an instruction register and instruction executing circuits for independently executing a portion of the functions required by an instruction being simultaneously executed by each subprocessor. Execution is initiated and synchronized by simultaneously loading the same instruction into each subprocessor.

A compact distributed-parameter network for transmission of applied electrical signals with a predetermined characteristic impedance, comprising a substrate of dielectric material having at least two parallel major surfaces with a coil of coplanar turns of electrically conductive material in a spirallike configuration of concentric squares in the center area of the coil and of concentric octagons in the outer area of the coil affixed to and supported by one of the parallel major surfaces, and a ...

Propellant charges for weapons, especially for the small caliber type, made f grains consisting of two layers, an outer slow burning composition and an inner or core composition for the control of interior ballistics. The charges consist of a plurality of increments of such type grains which differ in the thickness and composition of the outer layer and the thickness and composition of the core resulting in better control of interior ballistics, such, for example, as the obtention of higher velo...

An undesired resonance is prevented in a distributed transmission line filter comprising a center conductor having serially connected inductive and capacitive sections separated from a ground conductor by a dielectric substrate having a first thickness for filter inductive sections and a second thickness for at least one of filter capacitive sections.

A printshop management scheduling routine and system which provide optimum scheduling of printer jobs on a network. The scheduling routine utilizes the total complex of printers available at local location and/or remote locations to allocate and complete printer jobs based on a plurality of criteria, including requested completion time for the project. If requested completion time does not allow printing of the print job by a sole printer, the print job is allocated to a plurality of available p...

A reader for a distributed-optical microfiche wherein each page of recorded intelligence is constituted by a reduced scale image that is dissected to form a pattern of dispersed bits. The several patterns representing the recorded pages are interlaced to produce a multi-page microfiche that is read back by irradiating and enlarging only a selected pattern of dispersed bits and projecting this pattern onto a screen. The reader includes a lens matrix formed by an array of individual lenslets, each...

In operations such as seismic exploration seismic waves are generated at a shot point. The amplitudes of successive samples of seismic waves appearing at a plurality of detector stations variously spaced from said shot point in the wake of generation thereof are converted to digital codes. The codes from all the detectors are transmitted in sequence and on a real time basis by spread spectrum radio pulses to a master station. A plurality of data acquisition units each including a radio transpond...

A method is disclosed for performing a distributed computation for RF Management in a wireless communications network. The computation involves a sequence of computation stages. The wireless network has a plurality of base stations, each base station contributing data the computation. Each base station engages in a respective stage of the distributed computation. The sequence in which the base stations are engaged in the computation, known as the "follower order", is specified in advance and is ...

A method and apparatus for distributing compiling jobs among a number of sub-contractor computers in a network is described. The method involves publishing job-shops, which are computer capability descriptions of the sub-contractor computer to a network resource scheduler computer. The network resource scheduling computer compares modules of a compiling task sent from client computers with the published job-shops and forwards the modules as jobs to the chosen sub-contractor computer for completi...
