20150109178 | ANTENNA SYSTEM HAVING AT LEAST TWO APERTURES FACILITATING REDUCTION OF INTERFERING SIGNALS - Described embodiments include an antenna system and method. The antenna system includes at least two surface scattering antenna segments. Each segment includes a respective electromagnetic waveguide structure, and a respective plurality of electromagnetic wave scattering elements. The wave scattering elements are distributed along the waveguide structure, have an inter-element spacing substantially less than a free-space wavelength of a highest operating frequency of the antenna segment, have a respective activatable electromagnetic response to a propagating guided wave, and are operable in combination to produce a controllable radiation pattern. A gain definition circuit defines a series of at least two radiation patterns selected to facilitate a convergence on an antenna radiation pattern that maximizes a radiation performance metric. An antenna controller sequentially establishes each radiation pattern. A receiver receives the desired field of view signal and the undesired field of view signal. | 04-23-2015 |
20130081018 | Acquiring, presenting and transmitting tasks and subtasks to interface devices - A system includes an ignorant interface device subtask acquiring module configured to acquire one or more subtasks that are configured to be carried out by two or more discrete interface devices and which correspond to portions of one or more tasks, wherein at least one of the one or more tasks and an requestor of the one or more tasks are undisclosed to the two or more discrete interface devices, a corresponding subtask representation presentation module configured to present representations corresponding to the one or more subtasks, and a selected subtask data transmission module configured to transmit a subtask of the one or more subtasks corresponding to a selected representation. | 03-28-2013 |
