Abstract: A robotic cleaning system may include a robotic cleaner configured to generate a map of an environment and a mobile device configured to communicatively couple to the robotic cleaner, the robotic cleaner configured to communicate the map to the mobile device. The mobile device may include a camera configured to generate an image of the environment, the image comprising a plurality of pixels, a display configured to display the image and to receive a user input while displaying the image, the user input being associated with one or more of the plurality of pixels, a depth sensor configured to generate depth data that is associated with each pixel of the image, an orientation sensor configured to generate orientation data that is associated with each pixel of the image, and a mobile controller configured to localize the mobile device within the map using the depth data and the orientation data.

Abstract: An adaptive sensor array system and method includes receiving one or more signals from a sensor array and compare the received signals to one or more object detection threshold values, determining if the robotic cleaner was moving along a travel path for a predetermined period of time, window W, in response to a determination that the robotic cleaner was operating in straight-line motion during the window W, calculating a value of the received detected signals from the sensor array during one or more calibration periods C of the window W, and adjusting one or more of the object detection threshold values based on the calculated value during the window W. A sum of all the calibration periods C during window W is less than a length of the window W. One of the calibration periods C may start at a beginning of the window W.

Abstract: A system for measuring capacitance has a measurement circuit with a first reference capacitor connected to a first node and to a second node. Each of the nodes is connected to a unit operable to apply a reference voltage or ground to one of the nodes. Each node has a first pad connected to the first node and a unit operable to measure voltage between the first node and second node.

Abstract: A vehicle windshield wiper motor controller (10) includes a control circuit (15) and a power circuit. The power circuit can operate in dual modes, using a low cost MOSFET as the power switch during normal operation of the wiper motor, and a relay as the power switch during motor lugging and stall conditions. The controller (10) is part of a vehicle wiper system which includes a conventional wiper blade assembly positioned on the vehicle to engage the windshield or other window surface.
