Detection System For Power Tool
View pageUS Patent:
8186253, May 29, 2012
Filed:
Apr 28, 2010
Appl. No.:
12/769396

Abstract:
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.

International Classification:
B23Q 16/00
B26D 5/00
B26D 5/00
US Classification:
144356, 83 62
Abstract:
A power tool is disclosed. The power tool may comprise a movable blade and a detection system for detecting contact between the blade and an object. The detection system may comprise an excitation plate capacitively coupling the drive signal to the movable blade and a circuit in communication with the excitation plate. The circuit may be configured to generate 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 calculate an energy of the blade current signal considering the in-phase component and the quadrature component. The circuit may be further programmed to compare 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. The adaptive trigger threshold may be based on a sum of a first plurality of values comprising a fixed direct current (DC) offset, and a mean of the energy of the blade current signal.

20110228098, Sep 22, 2011
Filed:
Feb 10, 2011
Appl. No.:
13/025114
Inventors:
Brian Lamb - Belmont CA, US
Vladimir Tetelbaum - Redwood City CA, US
Vladimir Tetelbaum - Redwood City CA, US
International Classification:
H04N 5/33
H04N 5/225
H04N 5/225
US Classification:
348164, 348169, 348E0509, 348E05024
Abstract:
A method is provided to track an object, the method comprising: directing a video imager to perform image recognition to recognize a feature of the object within an imager field of view and to determine a position of the feature within the field of view; using an IR sensor to determine a position of an infrared (IR) transmitter; and automatically adjusting orientation of the imager as a function of the position of the recognized feature within the field of view and the determined position of the IR transmitter to follow movement of the object.
