Abstract: A method is provided that can include activating at least two wireless communication channels in parallel, between a first wireless transceiver and a second wireless transceiver. Each of the at least two wireless communication channels can operate at a different radio carrier frequency, and the first wireless transceiver may be part of a first vehicle. The method can also include transmitting, by the first wireless transceiver, common information in parallel on the at least two wireless communication channels to the second wireless transceiver and deactivating the at least two wireless communication channels.

Abstract: A spaceborne hybrid antenna reflector for dual frequency band illumination of common spot beam coverage regions contains an interior solid reflector region, that is adjacent at its perimeter to a ring-shaped exterior dichroic reflector region and adjoined by a common backing structure. The solid interior region is reflective to RF energy at each of first and second spaced apart frequency bands, while the exterior dichroic reflector region is reflective at the first frequency band, but non-reflective at the second frequency band. This allows the hybrid reflector to realize the same beamwidth coverage for a transmitter operating at one frequency band and a receiver operating at the other frequency band. The backing support frame at the rear side of the reflector is electrically decoupled from the exterior dichroic ring.

Abstract: A robotically controlled wiring apparatus for stripping, cutting and installing clad wire in a waffleline plate supported on an X-Y table comprises a wire feed, stripping and cutting unit, which is displaceable toward and away from the waffleline plate. The wire installation unit includes a clamp foot that is controlled by a cam unit to engage the wire and urge a first end of the wire into a channel of the waffleline plate. After the clamp foot has been retracted away from an inserted end of wire and the installation wheel is positioned against the wire, the X-Y table is translated, causing the wheel to rotate, drawing wire from a supply spool and effectively press-fitting the wire along the channel of the waffleline plate. After a prescribed length of wire has been installed, the wire is stripped and cut. For this purpose, the wire is clamped in the channel and placed in tension.
