CUTTING SYSTEMS AND RELATED METHODS
In some embodiments, a cutting system including a movable blade or a reciprocating blade operably coupled to a motor is disclosed, wherein the cutting system comprises a diverting feature. In some embodiments, a diverter proximity relative to the movable blade or reciprocating blade is selected to facilitate diversion of a material during cutting. In at least one embodiment, the movable blade may be movable blade for an oscillating tool. A cutting system according to the present invention may be coupled to a container, for example, a residential trash container or a residential recycling container.
TABLE SAW
A table saw includes a workbench, a support frame, a cutting assembly, a mounting device, and a first lighting mechanism. The workbench has a workplane. The support frame is used for supporting the workbench. The cutting assembly includes a cutting element, where the cutting element is disposed at least partially above the workplane, and a drive device that drives the cutting element to rotate around a rotational axis in a cutting plane. The mounting device is disposed above the cutting element. The first lighting mechanism is disposed on the mounting device and generates a first lighting region toward the cutting assembly.
Machine Tool Device
A machine tool device includes at least one motorized machining tool, at least one, particularly capacitive, sensor unit, configured to detect at least one foreign body in at least one detection area around the machining tool, and at least one closed-loop and/or open-loop control unit configured to trigger at least one action depending on at least one signal from the sensor unit. The sensor unit includes at least one antenna configured to emit at least one electrical and/or magnetic field, which defines the at least one detection area, and/or to detect the at least one foreign body depending on at least one change in the at least one electrical and/or magnetic field.
EMERGENCY EVACUATION TOOL
An emergency evacuation tool that is configured to be mounted within an operator cab of heavy equipment wherein the tool of the present invention is operable to facilitate evacuation of the cab by cutting through the safety cage surroundably present thereto. The present invention includes a housing having a motor and a power supply disposed in the interior volume thereof. A blade is present on one end of the housing wherein the blade is adjustable and axially aligned with the housing. The blade is surroundably mounted by a blade guard housing. The lower edge of the blade guard housing provides stabilization during use. A spark receiving member is secured to the blade guard housing. The emergency evacuation tool is releasably secured to a mounting case that is electrically coupled to the heavy equipment. The housing includes at least one handle that is rotatable about the housing.
Device and a Method for Improving Safety in a Cutting Saw Apparatus
A system and a method for improving safety in a cutting saw apparatus is disclosed. The system comprises an RC oscillation circuit connected to a cutting saw, a detection module to detect changes in the output of the circuit and a control module that controls the operation of the cutting saw. The user wears a conductive footwear when working with the cutting saw. The system also comprises a conductive layer disposed beneath the conductive footwear and the oscillation circuit to establish a conductive path. The user also wears hand gloves to enable working with conductive, non-conductive and semi-conductive materials. When the user's hands comes into contact with the cutting saw, the resistance characteristics of the circuit changes, resulting in a change in the output signal of the circuit. This change is detected by the detection module which triggers the control module to stop the cutting saw.
Power tool with lightweight actuator housing
A power tool assembly includes a drop arm assembly movable along a drop path between a first drop arm assembly position whereat a portion of a shaping device supported by the drop arm assembly extends above a workpiece support surface and a second drop arm assembly position whereat the portion of the shaping device does not extend above the workpiece support surface, an actuator housing configured to house a first actuating device at an active location at which a force from the first actuating device is transferred to the drop arm assembly, the actuator housing including a slit configured to position a second actuating device at an inactive location, and a control system configured such that when the first actuating device is housed, the control system controls the first actuating device to transfer the force to the drop arm assembly when an unsafe condition is sensed.

Blade-Height Optimization Indicator for a Table Saw
A blade-height optimization indicator for a table saw determines based on the rotational position of one or more blade guards of the table saw as they are displaced by a workpiece being cut whether the blade-height of the table saw is optimized relative to the thickness of the workpiece and provides a visual GO/NO-GO indication depending on whether the blade-height is determined to be optimized.

HANDHELD CIRCULAR SAW
There is provided a handheld circular saw comprising a main body. The main body comprises a fixed blade guard configured to receive a circular cutting blade having an axis of rotation. A graspable handle is arranged in a forward position on the main body to enable a user to wield the power tool in use and a movable blade guard is arranged to surround at least a part of the cutting blade. An actuator arrangement configured to move the movable blade guard from a first position to a second position, where a greater proportion of the cutting blade is exposed in the second position than in the first position, the actuator arrangement having an actuator grip to enable the user to activate the actuator arrangement. The actuator grip is located and arranged forwardly of the graspable handle to enable actuation by the fingers of the user's hand which is grasping the graspable handle in use.
