In one embodiment, a power tool includes a cutting assembly, a sensor system proximate to the cutting assembly, a reaction system operably connected to the cutting assembly, a memory, program instructions stored within the memory, a spatial recognition algorithm stored within the memory, and a processor operably connected to the reaction system, the sensor system, and the memory. The processor is configured to execute the program instructions to detect a man profile within a detection zone associated with the cutting assembly, establish a location of the human profile within the detection zone based upon the detection using the spatial recognition algorithm, determine that an unsafe condition exists based upon the established location, and activate the reaction system.

A co-extruded safety contact strip includes at least one contact or switching chamber situated in a section or profile and containing contactor or switching strips. One end of the base of the section is pivotally connected to a first side part and the other end of the base can be form-lockingly locked onto a second side piece. A method for securing the safety contact strip is also provided.

An apparatus for identifying when an individual is in proximity to an object having a sensor portion having an electromagnetic field. The apparatus has a personal alarm device that is worn by the individual which detects the presence of the magnetic field and produces a signal indicating the personal alarm device is within the electromagnetic field. The sensor portion having an exclusion zone where the electromagnetic field is effectively negated so the PAD does not produce an alarm in the exclusion zone. A method for identifying when an individual is in proximity to an object. A field extension module. A proximity device.

An arrangement for determining the movement of a machine to be secured after safety directed emergency signal, wherein the arrangement has a sensor module and a trigger module, wherein the sensor module is subsequently and releasably fastenable to the machine, and wherein the sensor module comprises: at least one sensor for detecting movement data describing the movement, a first trigger interface for the reception of a trigger signal that includes the point in time of the emergency signal, and a recording unit that is configured to store and/or output at least some of the movement data from the time period between the point in time of the emergency signal and the reaching of a safe state of the machine, and wherein the trigger module is configured for generating and/or receiving the safety directed emergency signal for the machine to be secured.

One embodiment of the invention disclosed herein provides techniques for assisting with performing a task within a smart workspace environment. A smart workspace system includes a memory that includes a workspace management application. The smart workspace system further includes a processor that is coupled to the memory and, upon executing the workspace management application, is configured to perform various steps. The processor detects that a first step included in a plurality of steps associated with a task is being performed. The processor displays one or more information panels associated with performing the current step. The processor further communicates with augmented safety glasses, augmented tools, and an augmented toolkit to safely and efficiently through a series of steps to complete the task.

An apparatus for protecting a power tool user includes a glove or other garment having at least one sensor that monitors proximity to the power tool. Glove embodiments can include finger and/or thumb proximity sensors, and/or sensors that detect hand position, finger and/or wrist joint angle, vibration, and/or acceleration. Sensing targets can be retroactively installed on the power tool, and can define warning and/or danger zones. Sensing can be via magnetic, electromagnetic, capacitive, eddy current, and/or range finding means. Sizes of warning and/or target areas can be controlled by selecting targets from a plurality of targets of various detection ranges. Protective responses can vary according to different sensed events, and can include audible, visual, and/or tactile alerts, and/or interruption of power to the tool. Embodiments can record proximity and/or status data during a work session for review, training, and certification purposes. A controller can be physically cooperative with the garment.

Various embodiments of a jobsite keep out zone system are provided. The system includes one or more detectors configured to determine when an intruder is within and/or is approaching a protected area. In response to the determination, one or more alarms and/or notifications are generated.

Machines with safety systems are disclosed. The machine may take the form of woodworking machines including table saws, band saws, miter saws, hand-held circular saws, pneumatic chop saws, radial-arm saws, jointers, planars, routers and shapers. The machines may include an operative structure configured to perform a task, where the operative structure includes a cutting tool adapted to move in at least one motion, and a safety system adapted to detect the occurrence of an unsafe condition between a person and the cutting tool and for mitigating the unsafe condition. The safety system may include a detection subsystem and a reaction subsystem. The machine may also include a bypass or override mode where in an injury mitigation system is disabled for certain cuts.

Table saws with safety systems are disclosed. The safety systems detect and react to dangerous conditions, such as contact between the blade and a person. The table saws may include a switch, a first light that illuminates to indicate the safety system is operable, and a second light that illuminates to indicate that the safety system is inoperable. The switch may not power the saw when switched on if the second light is illuminated.

A safety system includes safety glasses and an apparatus. The safety glasses include an electronic system having a sensor configured to detect when the safety glasses are worn by a user and a wireless communication device. The apparatus includes a body housing an electrical isolation device and a wireless communication device. The body includes a first end defining a female electrical socket, a second end defining a male electrical plug and a fastening device coupled to the body and configured to move from an open position to a closed position in which an electrical cord that is electrically coupled to the body at one of the first end or the second end is also physically secured to the body by the fastening device. The electrical isolation device is configured to prevent current flow in the line conductor included in the body when the safety glasses are not being worn by the user.
