Abstract: Systems and methods for determining a state of an appliance are provided. A controller determines a usage of the appliance. Responsive to determining the usage of the appliance, the state of the appliance is altered.

Abstract: Systems and methods are provided for an appliance system. The system includes an appliance, and a processor connected to the appliance such that the processor places the appliance in one of an enabled state and a disabled state. The processor is configured to track usage of the appliance and to place the appliance in a disabled state when the usage of the appliance exceeds a threshold amount. The system also includes a data receiving device configured to receive a code, wherein upon receipt of a valid code, the processor is configured to adjust the threshold amount to allow additional usage of the appliance.

Abstract: An autonomously powered system comprising a data receiving device and charge controller is provided. The receiving device receives a code comprising an amount, system serial number, and series number. The controller is in electrical communication with an appliance that provides electricity. The controller evaluates appliance usage against a threshold amount. The threshold amount defines an amount that the appliance can be in an enabled state before being disabled, either as a period of time during which the appliance is enabled, an amount of time the appliance is usable in the enabled state, or an amount of power that is used by the appliance before being disabled. Responsive to determining that appliance usage is less than the threshold, the appliance is enabled. Responsive to determining that appliance usage exceeds the threshold, the appliance is disabled. Responsive to determining that the code is valid, the threshold is adjusted responsive to the code.

Abstract: Methods, systems, and apparatus, including computer program products, for providing alternative search results for a query. In one aspect, a method includes transmitting a set of one or more search results for a query to a client device for presentation to a user, where each search result refers to a respective resource, receiving from the client device an alternative search result submitted by the user for the query, associating the alternative search result with the query, and storing in a repository the query and the alternative search result, where the alternative search result is transmitted with the set of one or more search results for a new search of the query.

Abstract: A heliostat control system includes a heliostat having a reflective surface and at least one reflective element, the reflective surface having a different radius of curvature than the at least one reflective element, a receiver configured to receive sunlight reflected from the reflective surface, and a camera configured to receive sunlight reflected from the at least one reflective element and to generate an image including pixels having a brightness dependent on an orientation of the reflective surface.

Abstract: A heliostat control system includes a receiver located within a receiver volume and a view port located proximate to the receiver volume. The receiver is configured to receive sunlight reflected from a mirror of a heliostat. The view port is optically connected to a camera, and the camera is configured to generate an image including pixels having a brightness dependent on an orientation of the mirror.
