Abstract: Systems and methods for electronic levels are disclosed. An electronic level can include one or more sensing elements configured to detect levelness of the electronic level. The electronic level can include a display including multiple output display elements arranged in an array that extends in a direction along a longitudinal axis of the electronic level and configured to display an indication of the levelness of the electronic level. The electronic level can include a controller coupled with the one or more sensing elements and the multiple output display elements. The controller may be configured to activate the one or more sensing elements to detect the levelness and activate one or more of the multiple output display elements to display the indication based on the levelness.

Abstract: An obscured feature detector operates from a stationary position on a surface being examined. The detector includes a plurality of sensor plates positioned in an array on the underside of the device, which sense the examined surface. The sensor plates are connected to a capacitance sensing circuit, which connects to indicators positioned on the back side of the detector through additional circuitry. A handle positioned on the back of the detector allows the user to grasp the device and place it in a stationary position on the surface being examined while also observing the indicators on the back side of the detector. Increases in capacitance caused by the presence of features behind or within the surface being examined are detected by the sensor plates and the capacitance sensing circuit. The indicators identify locations of larger capacitances, associated with the presence of a feature, such as a stud, beam, or electrical wiring.
