Abstract: A system for determining an initial angular position of a rotor of a synchronous machine includes a motor driver module configured to provide a motor driver voltage signal to the synchronous machine, the motor driver voltage signal being sufficient to induce an electrical current in the synchronous machine; and a rotor position determination module configured to receive an indication of the current generated in the machine and to determine the initial position of the rotor based on the indication of the current generated in the machine.

Abstract: The invention is a means of regulating how much snow is produced by a snowmaking machine based on the moisture in the environment. It utilizes a moisture sensor (such as a soil sensor), and a processor measures the resistance to determine how much snow should be made. The snow maker then receives this information and adjusts the quantity of snow that it produces. By using this invention, the value of water will be maximized and the snow will be made with the greatest efficiency.

Abstract: Example apparatus and methods concern a first device (e.g., phone) having a first set of input or output capabilities interacting with a second device(s) (e.g., tablet) having a second set of input or output capabilities. The first device may detect the second device and establish a communication link with the second device. The first device may receive inputs presented at the second device and provide outputs to be presented by the second device. In response to an action (e.g., touch, gesture) on the second device, an application running on the first device may receive an input, which may in turn determine an output that is provided to the second device. The first device may use the second device to provide an input/output experience that is superior to what the first device could provide with its own built-in input/output components. The combination saves energy and reduces computing complexity.
