A protection device for a laser system having at least one active laser and having at least one beam guide. Eye safety and/or protection for an exposed person is achieved using at least one additional laser as a warning laser which, operating in a visible spectral range, is used shortly before the active laser is used, and which, can cause at least one person to close his or her eyes and/or change his or her viewing direction away from the receptor point of the active laser beam on a target.

The current system and method relate to a tracking and feedback system. More specifically, the system and method comprise a tracking apparatus attached to a tracked entity, reader nodes, a central management database including software platform, and a feedback system incorporated within the tracking apparatus and the central management database.

A safety control device, a method of controlling safety control device, and a recording medium are provided. A detection zone in which the safety of an operator can be secured and a decrease in an operation rate of a machine can be minimized is set. A safety controller sets a detection zone for executing a safety operation when it is determined that an operator has entered for each operator.

An alarm screen comprises a frame comprising a laser sensor, a processing unit, and a wireless transmitter embedded in a hollow interior. The frame comprises an opening for the laser sensor to project a laser beam outside of the alarm screen. The laser sensor projects the beam through the opening, makes a set of one or more measurements of a distance between the laser sensor and an object in a path of the laser beam, and sends the set of measurements to the processing unit. The processing unit is configured to compare the distance measurements received from the laser sensor with a threshold distance detect, and send one or more signals to the wireless transmitter when at least one of the distance measurements received from the laser sensor exceeds the threshold. The wireless transmitter is configured to receive signals from the processing unit and wirelessly transmit the signals.

Display with high visibility without impairing rigidity of a housing is performed. A light curtain includes: a housing in which one element of a pair of elements disposed inside along a longitudinal direction in order to form the plurality of optical axes at intervals, the housing including a metal case and end members connected to both ends of the metal case; a cover that transmits light from a light projecting element, which is the one element, and is attached to the housing so as to cross the optical axe; an indicator lamp that is a light diffusing member disposed outside an outer surface of at least one of the cover and the housing along the longitudinal direction or formed in series with the cover; and an indicator lamp light source that is accommodated in the housing and supplies light for displaying toward the indicator lamp.

A process for dynamic vehicular threat detection perimeter modification for an exited vehicular occupant includes prior to detecting a vehicular occupant exiting the vehicle, establishing a first sized vehicular geofence surrounding the vehicle as a function of one or more stored vehicular perimeter distances. The first sized vehicular geofence is monitored for a first breach via one of a 360 degree vehicular light imaging and radio wave distancing system. In response to detecting that the vehicular occupant previously inside the vehicle has exited the vehicle, the one or more stored vehicular perimeter distances is modified as a function of a detected location of the exited vehicular occupant to establish a second sized vehicular geofence surrounding the vehicle different than the first sized vehicular geofence. The second sized vehicular geofence is monitored for a second breach via one of the 360 degree vehicular light imaging and radio wave distancing system.

A security system includes a plurality of laser scanners to establish light shields in an area to be monitored, with each of the light shields including at least one detection zone, and a controller to detect unauthorized entry to the area to be monitored based on a position and timing of breaks in the detection zones of the light shields.
