  • Patent number: 9020618
    Abstract: The present disclosure generally relates to techniques for controlling a device to perform a function, for example, window washing. A controller device may be adapted to control a controlled device. In response to hand movement, an accelerometer in the controller may obtain acceleration and/or angle signals. The signals may be processed in order to identify a command that may be used to control the controlled device. The controlled device may be secured to, for example, a window. Upon identifying command(s) initiated from the controller device, the controlled device may respond to the commands. The controlled device may include, for example, a cleaning unit. The command(s) may be instructions for the controlled device to move about the window and activate the cleaning system.
