A safety device is provided for monitoring at least one machine that has at least one sensor for generating sensor data on the machine and a processing unit for the sensor data that is connected at least indirectly to the sensor and to the machine and that is configured as a runtime environment having at least one computing node and to allow at least one logic unit to run on the computing node, wherein at least one logic unit comprises a safety functional unit for a safety relevant evaluation of the sensor data to output in the case of a safety relevant event a safety signal to the machine for triggering a safety response, In this respect, the processing unit is furthermore configured to generate and resolve logic units and/or to assign them to a computing node.

Systems and methods associate operators with machinery, such as materials-handling vehicles. Embodiments of the disclosed system comprise a first communication module configured to determine a distance between a frame of reference associated with a vehicle and respective portable devices and first logic configured to designate a first portable device as an operator device based, at least in part, on a first distance determined by the communication module. The first logic may be further configured to exclude the first portable device from a pedestrian detection function in response to classifying the first portable device as an operator device.

A power tool and methods are provided for detecting objects (e.g., flesh or other materials) in the operating path of a power tool's output component (e.g., saw blade or drill bit). An object detection sensor in the power tool generates an output signal indicative of a type of material detected in the operating path of the power tool. A power tool controller receives the object detection sensor output and determines when a material in the operating path of the power tool changes. The controller changes operation of a motor of the power tool (e.g., increasing or decreasing speed or stopping the motor) in response to the detected material change. The object detection sensor may include, for example, an RF sensor, a capacitive sensor, a camera, a conductivity probe, or an ultrasound probe.

A laser interlock system and allows laser radiation to be generated when an inspector and a subject correctly wear safety glasses and during use of a photo-acoustic imaging apparatus, thereby protecting the eyes of the inspector and the subject and preventing unnecessary power consumption. The laser interlock system includes a sensing unit to sense whether or not contact between a user and safety glasses occurs, a light source unit to generate a laser, and a control unit that determines, based on an output value from the sensing unit, whether or not the user is wearing the safety glasses normally, and generates an interlock signal to turn on or off the light source unit for selective laser generation according to the determination.

A control arrangement (20) comprises at least one sensor (7). The sensor (7) is adapted to detect at least one object (9) in an area of at least one predefined sector (10) focused in an area between a control cabin (5) and a boom end (11), and to detect at least one of the following: location information of said detected object at two different time instants, at least, and the speed of said detected object The control arrangement (20) additionally comprises at least one control unit (8) adapted to determine at least the direction of travel of said detected object (9) in relation to the control cabin at two different time instants, at least, on the basis of the detected location information and/or the detected speed of the object (9), and cause a change in the control of a forest machine in response to the detected direction of movement of the detected object (9) being directed towards the control cabin in the area of the sector (10).

Systems, devices, and methods are disclosed for a rosin press that allows improved extraction over existing presses. The press includes improved platens for rosin collection with built-in gutter rail collection systems and well-distributed force on the pressed product and multiple hydraulic rams. In addition, computerized systems are provided for controlling and monitoring the system in an automated fashion, as well as safety features to prevent injury and damage to the product, especially during automated pressing.

A method of localizing a person or object in a monitored zone using a safety system, having a movable machine, having a control and evaluation unit, having at least one radio location system, and having at least one spatially resolving sensor for the position determination of the person or object, wherein the radio location system has arranged radio stations, wherein at least one radio transponder is arranged at the person or object, wherein position data of the person or object can be determined by means of the radio location system, and wherein the position data are transmitted from the radio stations of the radio location system to the control and evaluation unit and position data of the person or object are determined by means of the spatially resolving sensor, wherein the control and evaluation unit compares the position data of the radio location system and the position data of the spatially resolving sensor and forms tested position data on an agreement.
