Abstract: Systems (200) and methods (300) for measuring geometric changes of a passive material (414) when heat and pressure are applied thereto. The methods involve forming a pad (108, 510) on a passive material panel (410). The pad includes at least one of a layer of a passive material (414) and a layer of a metal (416). The methods also involve coupling an interferometer (810) to the pad. The method also involves forming a multi-layer structure by placing at least one substrate panel (400) on top of the passive material such that an aperture (602) formed in the substrate panel is aligned with the pad. Pressure and heat are applied to the multi-layer structure. Data is collected using the interferometer while the pressure and heat are applied to the multi-layer structure. The interferometer can include, but is not limited to, a Fabry-Perot interferometer, a Michelson interferometer and/or a Mach-Zehnder interferometer.

Abstract: The conical monopole antenna includes a conical antenna element having an apex and a base, a conductive base member coupled across the base of the conical antenna element and a ground plane antenna element, e.g. a disc antenna element, adjacent the apex of the conical antenna element. A fold conductor is coupled between the conductive base member and the ground plane antenna element. The fold conductor may include at least one impedance element, such as a resistive element or inductive element. An antenna feed structure is coupled to the ground plane and conical antenna elements.

Abstract: A limited acknowledgement-based communication methodology increases the throughput efficiency of a relay-based, extended range, wireless packetized data transmissions to a data-reception site from a data-sourcing site, geographically remote with respect to the data-reception site. Rather than return an acknowledgement for each received packet, the data-reception site returns an acknowledgement only after receipt of a group of packets. When returning an acknowledgement, the data-reception site identifies which packets of the group were not successfully received. Missing packets may be retransmitted by the data-sourcing transmitter either immediately, or in response to a subsequent poll.

The method further includes puncturing the ring structure by removing at least one element therefrom to eliminate a statistical artifact in the random number sequence expressed in the second number base. The first number base and second number base are selected so that they are respectively defined by a first Galois field characteristic and a second Galois field characteristic.

Abstract: An adaptive compensation system for aspect ratio conversion. Video information, intended for her first aspect ratio display, e.g. the standard NTSC aspect ratio, is processed to determine additional information that can enable that video to be displayed and fill a wider aspect ratio screen. The processing can be a calculation which calculates, for example, texture, color and/or brightness of the edge portions, and automatically calculates video information to match the texture, brightness or color. The processing can be a database lookup, which automatically looks up likely portions from a database. The processing can also be an adaptive determination of what vertical portions of the image can be stretched without affecting the viewability, and then an adaptive stretching of different portions by different amounts.
