Abstract: An antenna array has a plurality of square or rectangular antenna assemblies. Each assembly includes a first antenna assembly surface with a solar cell and a second antenna assembly with one or more antenna elements. The antenna assemblies are interconnected without gaps therebetween to form a first contiguous array surface comprised of the first antenna assembly surfaces and a second contiguous array surface comprised of the second antenna assembly surfaces.

Abstract: The present disclosure relate to highlighting audience members with reactions to a presenter of an online meeting. Unlike physical, fact-to-face meeting that enables spontaneous interactions among the presenter and the audiences that are collocated with the presenter, presenting materials during an online meeting raises an issue of the present not being able to see real-time reactions or feedback by the audience members. The present disclosure addresses the issue by dynamically determining one or more audience members who indicate reactions during the online meeting or presentation and displaying faces of the one or more audience members under spotlight to the presenter. The presenter sees faces of the audience members with reactions during the online presentation and responds to the audience members and keep the audience engaged. The spotlight audience server analyzes video frames and determines types of reactions of the audience members.

Abstract: A technique for providing multi-sensory content receives input information that expresses a physiological state and experienced emotional state of a user. The technique generates prompt information that describes at least an objective of guidance to be delivered and the input information. The technique maps the prompt information to output information using a pattern completion component. The output information contains control instructions for controlling an output system to deliver the guidance via generated content. In some implementations, the pattern completion component is a machine-trained pattern completion model. In some implementations, a reward-driven machine-trained model further processes the input information and/or the output information. The reward-driven machine-trained model is trained by reinforcement learning to promote the objective of the guidance. In other implementations, the reward-driven machine-trained model operates by itself, without the pattern completion component.
