Abstract: An antenna assembly includes a first dielectric material, a ground plane above the first dielectric material, and two or more patch antennas above the ground plane. In an example, the ground plane has a first aperture slot, and a second aperture slot that is non-intersecting with the first aperture slot.

In an example, the first dielectric material comprises a printed circuit board (PCB). In some examples, the ground plane and the two or more patch antennas are manufactured using additive manufacturing techniques (such as three-dimensional printing techniques), and in some such examples, the second dielectric material includes dielectric foam. For example, the dielectric foam supports the two or more patch antennas above the ground plane.

Abstract: An antenna assembly includes a ground plane having a first aperture slot and a second aperture slot. The first and second aperture slots are non-intersecting and substantially symmetrical with each other about an imaginary plane of symmetry that divides the ground plane into two substantially symmetrical halves, and that is orthogonal to the ground plane. The antenna assembly includes a first patch antenna above the ground plane, and a second patch antenna above the first patch antenna. The first patch antenna is separated from the ground plane, and the second patch antenna is separated from the first patch antenna. The imaginary plane also divides the first patch antenna into two substantially symmetrical halves, and divides the second patch antenna into two substantially symmetrical halves. A first feed line and a second feed line are at least in part below the first aperture slot and the second aperture slot, respectively.

The distortion effect is random due to the headgear having optical distortion devices which dangle freely in front of the wearer's face and may both swing in two dimensions and rotate in a third dimension or may themselves bend. A circlet or bridge with temples and temple tips is worn about the crown of the head or around the face from ear to ear, with an extension from the front carrying one or more suspension members in turn carrying one or more optical distortion devices. The suspension members may be limber members and the optical distortion devices may be lenses, Fresnel lenses, strips of transparent or translucent and flexible materials, Fresnel lenses, material simply having a refractive index different than air, etc.

Abstract: Systems and methods are described for providing previews of deployment of data stream processing instructions sets, sometimes called pipelines, to a stream data processing system. Rather than deploying such an instruction set, which may cause detrimental side effects, previews can be facilitated by conversion of a data stream processing instructions set to a batch query that is applied to an existing data set. An output of the batch query can then be provided to an end user as a preview of output of the data stream processing instructions set, when implemented.
