One variation of a method for monitoring an object during a presentation, includes: initiating capture of a video with a camera defining a field of view, the camera arranged on a first side of a mobile computing device supported on a base device; generating a position signal defining a position of the remote device relative to the camera; in response to wirelessly receiving a first input selection from the remote device, indexing through digital slide content rendered on a display arranged on the first side of the mobile computing device; in response wirelessly receiving sensor data from a remote device coupled to the object, generating an event tag including a timestamp; and generating a multimedia stream including the video, the position signal data, digital slide content, the first input selection, and the event tag.

Automatic tracking, recording, and teleprompting device using multimedia stream with video and digital slide

Power tool includes a movable blade and a detection system for detecting contact between the blade and an object. Detection system includes an excitation plate capacitively coupling the drive signal to the movable blade. A circuit generates an in-phase component signal and a quadrature component signal from a blade current signal indicative of the instantaneous current drawn by the movable blade and calculates an energy of the blade current signal considering the in-phase and the quadrature components. The circuit compares the energy of the blade current signal to an adaptive trigger threshold to detect contact between the blade and the object based on whether the energy of the blade current signal is greater than the adaptive trigger threshold.
