Abstract: An originating host (101) splits a software agent into a code unit (103) and a data unit (105) and forwards the data unit (105) to a destination host (107). Once the destination host (107) receives the data unit (105) from the originating host (101), the data unit (105) is combined with a code unit (109), associated with the data unit (105) but not sourced by the originating host (101), forming a destination agent. The destination agent is executed.

Abstract: A component of a system receives a first instruction at a server to execute a target program that is unsupported by a server application. The server application is located on the server. A component of the system employs a second instruction in the supported program to cause execution of the target program. The second instruction is based on the first instruction. The supported program is supported by the server application.

Abstract: An input transformer for a coaxial transmission line is provided which allows continuously variable amplitude and phase of an RF signal conducted on the transmission line. The transformer comprises a housing having a longitudinal axis. A center conductor of the coaxial line extends along the axis through the housing. A first sleeve is axially movable within the housing, and has contact points on an outer surface thereof to provide electrical conductivity between the first sleeve and the housing. The ability of the first sleeve to move axially enables variability in the location of the transformer along the transmission line. The first sleeve has an inner wall that is eccentric relative to the longitudinal axis of the center conductor. A second sleeve having a cylindrical outer wall is disposed within the first sleeve. The second sleeve is rotationally movable within the first sleeve, and has contact points on the outer wall to provide electrical conductivity between the first sleeve and second sleeve.

Abstract: A frequency synthesizer using a fixed oscillator driving a comb line generator to generate a spectrum of comb lines, one of which is selected by a switched array of fixed-tuned, YIG passband filters. The selected comb line is combined in a mixer with a signal from a local oscillator, which, preferably, is a direct digital synthesizer. The output of the mixer is fed to another switched array of fixed-tuned YIG passband filters where only the desired sideband is selected and the comb line and the other sideband is filtered out. In various alternative embodiments, tunable YIG filters are substituted for each array. Some embodiments also use a reverse slope equalizer to break up the coherent energy in the comb line spectrum at the output of the comb line generator to allow RF amplification to be applied without saturating the amplifier.

Abstract: A pressure swing adsorber system includes a pneumatically driven booster compressor to increase the pressure of the output product gas. A pair of inlet valves controls feed air flow to the sieve beds and the drive cylinder of the booster compressor and are cycled so that one valve opens to pressurize one sieve bed before the other valve closes to allow the other sieve bed vent to atmosphere. During the time that both valves are open, the pressure in the two sieve beds and on opposite sides of the drive cylinder equalize and a portion of the gas in the pressurized sieve bed and drive cylinder side is captured rather than being vented to ambient. System efficiency is increased by selecting whether captured gas from the last pressurized sieve bed or drive cylinder side reaches the next to be pressurized sieve bed first.

Abstract: An Angle of Arrival/Long Baseline Interferometer (AOA/LBI) passive ranging apparatus and method for emitter range determination can use any convenient airframe location for the two-antenna uncalibrated LBI baseline. This baseline has a theoretically unlimited length and does not require a specific SBI/LBI baseline ratio. Only a single initial AOA is required. Range partitions are formed along the single AOA. The emitter is assumed to lie in any of N range bins and the corresponding DOA (direction of arrival) unit vectors computed. Each of these DOA unit vectors is then used to predict the LBI phase differential and the N resolved LBI phases each drive a location estimator. The location estimator (filter) with consistent output provide the emitter range. The LBI range from these filters is used for subsequent DOA generation and ambiguity resolution.

Abstract: A system for measuring the earth's magnetic field includes a magnetometer and apparatus for maintaining a predetermined magnetometer tilt in the magnetic meridional plane regardless of changes in vehicle heading. The magnetometer is of the type whose optimum measurement sensitivity is defined by a cone of predetermined angle that is symmetric about its optical axis. It is engaged to a planar platform by gimbal apparatus forming orthogonal axes of rotation that cooperates with a rotatable hemispherical strip to allow the magnetometer to be continuously repointed during changes in the heading of a carrier vehicle so that it is maintained in the magnetic meridional plane at a predetermined tilt angle.

Abstract: An eddy current coupling has rotating and non-rotating flux paths to use the rotating portions as both magnetic and mechanical members, reduce physical dimensions of the coupling, and improve heat dissipation from the coil.The coupling (10) has an inductor (20) mounted on the input shaft. A magnetic rotor (22) is mounted on the output shaft with poles (30, 32) spaced from the inductor. A field coil (36) is positioned radially inwardly from the rotor and generates a flux, causing torque transmission between the inductor and rotor.A stationary field coil support (38) is mounted in proximity to the rotor poles for providing a stationary flux return path between the poles. The support is positioned with respect to the rotating element of the coupling, so that these elements may provide a rotating flux return path in parallel with the stationary flux path of the support.

Abstract: A non-slip material used, e.g., as a handle grip covering provided for replacing the usual material wrapped around the handle of, for example, a golf club or tennis racket. The material may be used to cover any surface where non-slip is desired. The covering comprises a substrate coated on one side with a foamed material comprising, for example, a vinyl copolymer resinous binder containing expanded microspheres. A wax coating covers the foamed material coating. This handle covering is wrapped around a handle. It provides a non-slip, perspiration absorbing handle cover.
