Clothing equipment having a visual light communication emitter arranged to communicate a status of the clothing equipment, includes a light emitter arranged to emit flash light which is modulated at at least one target frequency in a dedicated non-visible spectrum, the light emitter including three fixed emitting portions distant from each other by predetermined distances, so as to authenticate the status of the clothing equipment.

Image sensors distributed about a workcell including industrial machinery are registered using a registration object and an information tag associated therewith. The tag contains information specifying the location of the object and/or the pose of the object. This information is acquired along with images of the registration object, and the sensors are registered based at least in part on the images and the acquired information.

An obstacle determination unit determines whether an obstacle is present in a periphery of the work machine. An action detection unit detects an action of an operator of the work machine. An action determination unit determines whether the detected action is a confirmation action executed at the time of safety confirmation. A notification unit changes a mode of notification when the action is determined to be the confirmation action.

A safety system for use with a power tool that is usable by a user, the power tool including a base and a moving component that is movable relative to the base, includes a sensor assembly and a controller. The sensor assembly monitors a predetermined danger zone that is adjacent to the moving component of the power tool. The sensor assembly is configured to generate data relating to the predetermined danger zone. The controller receives the data from the sensor assembly and analyzes the data from the sensor assembly to determine if at least a portion of a hand of the user is present within the predetermined danger zone. The safety system can further include a wearable component including infrared only reflective material that is coupled to the hand of the user. The controller analyzes the data from the sensor assembly to determine if the wearable component is present within the predetermined danger zone.

Proposed is a device and a method for preventing worker safety accidents during machining and, more particularly, a device and a method for preventing worker safety accidents during machining, which can prevent worker safety accidents in advance by stopping an operation of a chuck or cutter and triggering an alarm when a part of a worker's body is present in the danger zone beyond the safety zone judged by an artificial intelligence (AI)-based analysis of work images/videos captured during turning, milling, and other machining using chucks or cutters.

Systems and methods for determining safe and unsafe zones in a workspace—where safe actions are calculated in real time based on all relevant objects (e.g., some observed by sensors and others computationally generated based on analysis of the sensed workspace) and on the current state of the machinery (e.g., a robot) in the workspace—may utilize a variety of workspace-monitoring approaches as well as dynamic modeling of the robot geometry. The future trajectory of the robot(s) and/or the human(s) may be forecast using, e.g., a model of human movement and other forms of control. Modeling and forecasting of the robot may, in some embodiments, make use of data provided by the robot controller that may or may not include safety guarantees.

A method for controlling personal protective equipment. The method includes positioning of a person equipped with personal protective equipment next to an electrical enclosure, wherein a specific personal protective equipment requirement is defined for the electrical enclosure. The method further includes scanning the personal protective equipment in a contact-less manner while the person is next to the electrical enclosure. Thereby scanned personal protective equipment information are generated. The method further includes comparing the scanned personal protective equipment information with the specific personal protective equipment requirement and evaluating, based on the comparison, whether the personal protective equipment is in accordance with the specific personal protective equipment requirement. The method further includes providing a feedback indicating whether or not the personal protective equipment is in accordance with the specific personal protective equipment requirement.

A method for monitoring a robot arrangement, which robot arrangement has at least one robot includes capturing optical signals from a plurality of signal sources at least one sensor, wherein the signal sources and/or the sensor is/are positioned on the robot arrangement and triggering a monitoring reaction if a deviation of an actual arrangement of the captured optical signals from a desired arrangement of these signals exceeds a limit value. In one aspect, a reaction may be triggered if at least a predefined minimum number of signals from the desired arrangement is not present in the actual arrangement of the captured optical signals.

A computer-numerically-controlled (CNC) machine is configured to (i) measure a power of a beam of electromagnetic energy at a location between a source of the electromagnetic energy and a destination in the CNC machine, the beam of electromagnetic energy traveling from the source to the destination being susceptible to one or more interferences, and the one or more interferences being capable of altering the power of the beam of electromagnetic energy by at least diverting, away from an intended path for the beam of electromagnetic energy, at least a portion of the beam of electromagnetic energy, (ii) detect, based at least on the measured power of the beam of electromagnetic energy being less than a threshold value, an interference of the beam of electromagnetic energy, and (iii) in response to detecting the interference of the beam of electromagnetic energy, perform one or more actions.

A device for assisting with the safe use of a machine. The device has a user interface for displaying an augmented reality scene, a camera for capturing, in real time, video of an area of interest for inclusion in an augmented reality scene, a positioning module for determining the position of the device relative to the machine, a shape recognition module for recognizing an actual location near the machine in the video, a database of virtual safe areas around the machine, which are displayable in the augmented reality scene and a matching module for matching the virtual safe areas to the corresponding actual component, to identify to a user, in the augmented reality scene, areas around the machine which are safe and corresponding areas which are unsafe. A library of signs, arrows and the like, which are displayable and represent hazards, prohibitions and mandatory actions to the user, are available.
