Abstract: A mesh-networked sensor platform has a mesh network of nodes that connect with existing electrical infrastructure or are powered through other means such as batteries or energy scavenging. The mesh network forms a self-healing and self-configuring network robust against individual node failures. Wireless mesh networking integrated circuits (ICs), energy monitoring ICs and solid state relays are used to create a low-cost, easy-to-install energy visualization and management system. The system can intelligently control energy usage at the sockets to stop energy from being wasted. Software for a central base station uses energy usage data from each node to create an energy usage profile to automatically detect anomalies in energy usage and take steps to correct them. Other sensors can be easily added for a multitude of applications. Power usage and control of each appliance can be viewed via an interne connected PC or smart phone via a social networking website.

Abstract: A phased array satellite communication (SATCOM) system for ground stations receives information signals and a beam from a satellite and autonomously steers communication signals by phase information toward a satellite extracted from the received satellite beam. The new phased array eliminates the need for phase shifters to control a beam. The new phased array satellite communications system avoids delay in digital signal processing or feedback systems to find satellite locations, enabling autonomous real-time electronic beam steering with no delay. The new system is also used to handle signals from and to multiple satellites simultaneously. The new system is useful in other applications where an enhanced point-to-point communication link is required.
