POWER TOOL WITH CIRCUIT FOR SENSING CONTACT BETWEEN AN IMPLEMENT AND AN OBJECT
A power tool includes a sensing circuit mounted on a printed circuit card is electrically connected to a switching power supply that supplies electrical power to the sensing circuit. The sensing circuit is not connected to earth ground to enable detection of an operator approaching a moving implement without the operator necessarily being electrically connected to earth ground.

SYSTEM AND METHOD FOR IDENTIFICATION OF CONTACT BETWEEN A HUMAN AND A STATIC IMPLEMENT IN A POWER TOOL
A method of operating a power tool detects human contact with a non-moving implement in the power tool. The method includes generating a series of samples of an electrical signal passing through the non-moving implement, identifying a component for each sample in the series of samples of the electrical signal, identifying a first max-min value corresponding to a first plurality of samples in the series of samples occurring during a first periodic time interval with reference to a difference between a maximum value and a minimum value identified in the components of the first plurality of samples, and identifying human contact with the non-moving implement in response to the first max-min value being greater than a first predetermined threshold.

POWER TOOL AND METHOD THEREFOR WITH A PROXIMITY BASED THERMAL PROFILING
A power tool includes an actuator that moves an implement, an infrared sensor, and a range sensor. A controller in the power tool receives temperature data and range data corresponding to objects in a region proximate to the implement. If an object has a temperature within a predetermined range and is identified as being within a predetermined minimum distance of the moving implement, then the controller deactivates the actuator to halt the implement.

Embodiments of the present invention disclosed herein present forms of a method and mechanism for a power tool lock-off, wherein accidental activation of the power tool (10) may be inhibited. Pressing a lock-off release button (30) on the tool housing (12) induces a locking member (32) to move from a first position to a second position, allowing a trigger (20) to access a power switch (50)within the housing. Various forms and methods of lock-off mechanisms are enabled.

H01H 9/06 - Casing of switch constituted by a handle serving a purpose other than the actuation of the switch, e.g. by the handle of a vacuum cleaner
A power tool having a depth adjustment mechanism includes a motor housing (18), a support base (12) for supporting the motor housing (18), and a depth adjustment member (32) coupled to the support base (12) and movable between two positions, wherein the depth adjustment member (32) in a first position contacts a surface portion of the motor housing (18) and in a second position is distanced from the surface portion of the motor housing (18), such that the movement of the depth adjustment member from the first position to the second position is in a direction parallel to a plane that is substantially tangent to the surface portion of the motor housing (18).
A jigsaw comprises a housing (100), a motor (1) fixed in the housing (100) and a driven shaft (6) rotatably mounted in the housing (100). A transmission mechanism is used to transmit the output rotation of the motor (1) to the driven shaft (1). Two eccentric type outputs are obtained from the driven shaft (6) for driving the saw blade to reciprocate and oscillate simultaneously. The jigsaw is compact and light weighted and is easy to manufacture and use.
