Title
(EN) POWER TOOL HAVING OBJECT DETECTION
(FR) OUTIL ÉLECTRIQUE AYANT UNE DÉTECTION D’OBJET
Abstract
(EN)
A power tool and methods are provided for detecting objects (e.g., flesh or other materials) in the operating path of a power tool's output component (e.g., saw blade or drill bit). An object detection sensor in the power tool generates an output signal indicative of a type of material detected in the operating path of the power tool. A power tool controller receives the object detection sensor output and determines when a material in the operating path of the power tool changes. The controller changes operation of a motor of the power tool (e.g., increasing or decreasing speed or stopping the motor) in response to the detected material change. The object detection sensor may include, for example, an RF sensor, a capacitive sensor, a camera, a conductivity probe, or an ultrasound probe.

La présente invention concerne un outil électrique et des procédés pour détecter des objets (par exemple, de la chair ou d’autres matériaux) dans le trajet de fonctionnement d’un composant de sortie d’outil électrique (par exemple, une lame de scie ou un foret). Un capteur de détection d’objet dans l’outil électrique génère un signal de sortie indicatif d’un type de matériau détecté dans le trajet de fonctionnement de l’outil électrique. Un dispositif de commande d’outil électrique reçoit la sortie du capteur de détection d’objet et détermine le moment auquel un matériau dans le trajet de fonctionnement de l’outil électrique change. Le dispositif de commande change le fonctionnement d’un moteur de l’outil électrique (par exemple, en augmentant ou en diminuant la vitesse ou l’arrêt du moteur) en réponse au changement de matériau détecté. Le capteur de détection d’objet peut comprendre, par exemple, un capteur RF, un capteur capacitif, une caméra, une sonde de conductivité ou une sonde ultrasonore.
