A supplemental safety system (10) and a method for use of the same are disclosed. In one embodiment of the system (10) a safety site plan (18) of a site and a safety site schedule (20) for the site are utilized. The safety site plan (18) includes a site plan of the site augmented with locationing information for work with a project geofence (58) therearound. The safety site schedule (20) for the site includes a work schedule for the site augmented with schedule data relative to a project pre-work phase (72), a project work phase (74), and a project post-work phase (76). The safety site plan (18) and the safety site schedule (20) are utilized to provide safety as a project advances from project pre-work (72) to project work (74) to post- work (76).

Systems, methods, and computer-readable media for mitigating collision occurrences on a drilling rig, of which an example of the method includes associating ultra wide band (UWB) tags with pieces of rig equipment and rig personnel. The tags are configured to communicate with one or more anchors. The method also includes determining interlock rules associated with each of the pieces of rig equipment, monitoring positions of the pieces of rig equipment and the rig personnel using the tags, in real-time, determining that one or more of the interlock rules are violated by a position of one or more of the pieces of rig equipment, rig personnel, or both, and, in response to determining that the one or more of the interlock rules are violated, at least partially disabling operation of one or more of the pieces of rig equipment.

A fall-protection system including a harness and a fall-protection apparatus with a lifeline bearing a connector configured to be connected to the harness; and, a fall-protection monitoring system with a base unit and with at least one sensor module configured to sense a condition of the connector and to communicate a signal indicative of the condition of the connector to the base unit.

A method for determining a protection zone with a protection radius about a wireless communication object transponder, wherein the method includes a) ascertaining a first indefinite position of the object transponder using a first locating system, b) ascertaining at least two definite anchor object distances between the object transponder and at least two anchor gateways with respective known positions via a definite distance measuring device using a two-way ranging method, and c) ascertaining the protection radius using a failsafe computing device which receives the first indefinite position from the first locating system and the at least two definite anchor object distances from the distance measuring device and determines the protection radius therefrom using the known positions of the at least two anchor gateways.

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.

A safety system for a machine having a danger zone includes an induction coil having one or more turns extending along the periphery of a part of a worker's body as, for example, extending alone the fingers of a glove worn by the worker. A drive circuit applies a time-varying current having an identifiable characteristic such as the frequency of an alternating current. A magnetic field having the characteristic of the time-varying current is induced in an omnidirectional magnetic field sensor mounted adjacent the danger zone. The magnitude of this field is monitored. When the magnitude exceeds a threshold, a warning signal is issued and protective action may be taken, such as stopping or reversing the machine.

A radar system controls accesses to an environment where a machinery can be present. Radar devices are placed along an access path to the environment. The radar devices check the presence of targets in passage regions, arranged to be sequentially met along the access path. A control unit has stored predetermined ordered entry and exit sequences of events, given by changes of the passage regions between occupied and clear. If the registered sequence matches the entry sequence, that is the passage regions are occupied in the correct order, the environment is classified as occupied, and the machinery stops working. The machinery restarts when the environment is classified again as clear, based on the registered sequence matching the exit sequence, that is the passage regions being cleared in order.

A method of protecting humans in an environment of a moving machine is provided that comprises the environment being monitored by means of a protective device that is configured to detect one or more kinematic parameters of a respective object located in the environment and controlling the moving machine in dependence on detected kinematic parameters of the respective object to initiate a protective measure. The protective equipment here detects the polarization properties and a movement modulation of the respective object in dependence on which the respective object is classified with respect to whether the respective object is a human. In particular only when the respective object was classified as a human, the protective equipment controls the moving machine to initiate the protective measure in dependence on detected kinematic parameters of this respective object.

The present disclosure relates to a control system adapted to control an operation of a first and a second vehicle operating at a work site. The present disclosure also relates to a corresponding computer implemented method and to a computer program product.

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.
