Abstract: A method of assembling an antenna aperture from a plurality of antenna aperture segments is described. The method may include placing a first aperture segment relative to a second aperture segment to partially form the antenna aperture. Furthermore, an overlap of the first aperture segment overlaps a complementary underlap of the second aperture segment at a seam. The method may also include joining the overlap of the first aperture segment to the underlap of the second aperture segment to partially form the antenna aperture.

Abstract: Techniques and mechanisms for providing a low-profile terminal for satellite communication. In an embodiment, a communication terminal includes a radome, an array of radio frequency (RF) elements and a foam layer disposed therebetween. The foam layer includes a first side and a second side opposite the first side, wherein the array of RF elements and the radome are coupled to the foam layer via the first side and the second side, respectively. The communication device provides contiguous structure between the radome and the array of RF elements. In another embodiment, the first side forms a machined surface which contributes to flatness of one or more antenna panels having the array of RF elements disposed therein or thereon.

Abstract: A method and system for integrating data-handling policies into a computer-implemented workflow model is provided. In one embodiment, a workflow editor implemented using one or more processors may include a privacy manager module configured to permit a business process designer to integrate data handling policies into a workflow model. A privacy manager module, or simply a privacy manager, may also be configured to execute a consistency check with respect to newly-created and existing data handling policies to determine whether there is a conflict among any of the data-handling policies associated with tasks and data objects of the workflow model.

Abstract: According to a general aspect, a computer-implemented method for a first user to verify an association with a second user through a secret handshake protocol includes maintaining information about a reusable identification handle for the first user, where the information about the reusable identification handle is provided by a trusted third party, maintaining information about a reusable credential for the first user, where the information about the reusable credential is provided by a trusted third party, and maintaining information about a matching reference for verifying an association with another user, where the information about the matching reference is provided by a trusted third party. Information based on the reusable identification handle and based on the reusable credential is transmitted to a potential peer. First information based on a reusable identification handle for the second user is received, and second information based on a reusable credential for the second user is received.
