Abstract: Accuracy of derivation of local corrections to GPS signals for use for aircraft landing guidance is subject to effects of reflected multipath signals. Antennas with a near-spherical antenna pattern of right-hand circular polarization, except within a downward cone, provide suppression of reflected multipath GPS signals incident from all azimuth angles and all relevant elevation angles. For such an antenna a cylindrical top assembly may include spaced conductive disks with intermediate exciter members excited at increments of 90 degree phase and surrounded by a dielectric ring. A cylindrical base assembly may include signal absorbent top and side wall portions and a bottom conductive disk and may alternatively include a signal absorbent inner wall portion.

Abstract: GPS reception on helicopters and ground vehicles may be subject to varying near-ground interference. A compact antenna includes vertically spaced arrays of radiating elements. The first array provides a basic reception pattern. The second array provides a pattern having a distinctive low elevation angle phase reversal. By combining signals for these patterns an antenna pattern with a low angle onmidirectional elevation null characteristic is provided to suppress near-ground interference. Prior to combining, signals from the second array may be modified in amplitude or phase, or both, on a semi-permanent basis, or may be adaptively modified on an active basis, in order to adjust the null characteristic. Antennas and methods are described.

Abstract: A thermoplastic material, and in particular a jacket for an electrical cable, and more particularly a jacket for a THHN electrical cable, includes a polyamide base material, a silicon elastomer and an ethylene polymer modified with an unsaturated aliphatic diacid anhydride. The silicon elastomer does not migrate through the jacket. The jacket has a lower coefficient of friction than a cable with a jacket that does not have a silicon elastomer incorporated therein, and the resulting cable requires less force to install than a cable without a lubricant incorporated therein. The cable also has improved flame resistance and elongation-to-break properties. Methods for making these thermoplastic materials are also described.

An optical source introduces optical radiation into the body part, and an optical detector receives optical radiation that has propagated through at least a portion of the body part and produces a first signal representative of the received optical radiation. The first signal is processed to produce a chromophore level metric, which is output on a user display, and is further processed to produce a second signal known to exhibit measurably significant timewise fluctuations corresponding to at least one intrinsic physiological oscillation of the patient when the optical source and the optical detector are in proper optical coupling with the body part. An error condition indication is provided if the measurably significant timewise fluctuations are not present in the second signal.

Abstract: A GPS antenna with anti-jam capabilities utilizes eight resonant loop radiator elements in a resonant exciter configuration to make available a primary and up to seven auxiliary antenna patterns usable with multi-pattern adaptive processing for anti-jam operation. Antennas as described enable desired radiation characteristics to be provided in a configuration of small size suitable for replacement of existing GPS aircraft antennas which lack anti-jam capabilities, in order to enable reliable GPS reception during airborne operations in the presence of interference or jamming. With enablement of multi-pattern adaptive processing, reduced-gain pattern notches or nulls may be employed to track and reduce the effect of incident signals which would otherwise jam or interfere with reception of GPS signals.

Abstract: Ground based GPS antennas for differential applications may be subject to intentional or other interference signals incident at low elevation angles. Described GPS antenna systems are usable to provide an antenna pattern having a vertically-steerable null. An array of vertically spaced radiator units having omnidirectional azimuth characteristics provides a primary reception pattern. Vertically intermixed radiator units employed on a separate or shared basis provide an auxiliary reception pattern. By subtractively combining the auxiliary pattern with the primary pattern and adjusting the relative signal level of the auxiliary pattern a vertically-steerable pattern null is provided. The antenna system may include an adaptive control system responsive to an antenna output signal to derive a steering signal to adjust the relative signal level of the auxiliary pattern to steer the vertically-steerable null to provide interference suppression. Antenna systems and methods are described.

Abstract: Dual-array two-port GPS antenna systems can provide horizon to zenith reception for differential GPS applications. On a single mast, an antenna system may include a lower array of sub-arrays (e.g., fifteen sub-arrays) to provide elevation coverage from horizon up to about 55 degrees elevation and an upper array of sub-arrays (e.g., three sub-arrays) to provide elevation angle coverage from zenith down to about 55 degrees elevation. Each sub-array may be of the same construction including four dipoles positioned at different azimuth locations and configured to provide a progressive-phase-omnidirectional (PPO) azimuth pattern suitable for reception of circularly polarized signals. In a particular embodiment the three sub-arrays of the upper array have PPO azimuth patterns with differing azimuth alignments and differing excitation values to provide a desired elevation angle coverage characteristic.
