A safety power assist for a manual press is provided. In another aspect, a press includes a tool, a manual actuator, a switch and an automatically powered actuator. A further aspect of the present press employs a spring which must be compressed beyond a predetermined pinching force before a switch is activated, where switch activation causes an automatically powered actuator to advance a workpiece-contacting punch or tool.

A control system for use with a hot work enclosure is illustrated and described herein. The control system comprises an air supply shutdown controller, at least one air supply gas detector, and an air supply shutdown module. The air supply shutdown controller is configured to receive an air supply gas detection signal from the at least one air supply gas detector in response to the presence of gas in air to be provided to the enclosure by an air supply system. The air supply shutdown controller is configured to be responsive to the air supply gas detection signal to provide an air supply shutdown signal to the air supply shutdown module to stop the supply of air to the hot work enclosure by the air supply system. The air supply shutdown module is beatable at a first position in the air supply system, and the at least one air supply gas detector is beatable at a second position in the air supply system, such that, in use, the gas-contaminated air detected by the at least one gas detector is prevented from passing through the air supply shutdown module.

A connector locking wire operation mechanism capable of buffering an impact on a push rod includes a body provided with a push rod rotatable along an arcuate track and a cam rotatable about a circular hole. A sector notch capable of accommodating the cam and leaving sufficient space is provided at an inner side of the push rod. The push rod and the cam are cooperatively rotatable about a common rotation axis. Both sides of the cam are in contact with the push rod and a spring plate respectively.

A dynamic rollover zone detection system that is easily attached to mobile machinery and dynamically detects a rollover zone around the mobile machinery. The system detects humans and objects within the rollover zone using one or more pre-trained machine learning models in order to prevent accidents and potential collisions between machinery and people or objects in the rollover zone. If a human or obstacle is identified in the rollover zone, an alert or warning is provided and/or the mobile machinery is disabled.

An electric working machine may include a support rod extending in a front-rear direction; a head unit attached to a front end of the support rod and including a front tool and a motor configured to drive the front tool; and a grip unit attached to a rear end of the support rod. The grip unit may include a grip housing configured to be gripped by an operator; a detection sensor attached to the grip housing and configured to detect an on/off operation for the motor by the operator; and a presence sensor attached to the grip housing and configured to detect a grip by the operator on the grip housing. The support rod may not penetrate through the grip housing. In a rear plan view of the electric working machine, at least one of the detection sensor and the presence sensor at least partially may overlap the support rod.

A connector locking wire operation mechanism capable of buffering an impact of a push rod. The mechanism comprises a device body (4). A push rod (1) which is rotatably connected along an arc-shaped track (5), and a cam (2) which rotates about a circular hole (12), can be mounted on the body (4). The push rod (1) has a sector-shaped notch (6) on an inner side thereof and is capable of accommodating the cam (2) and leaving an extra space. The push rod (1) and the cam (2) cooperate with each other, and both can rotate around a common rotation axis thereof. The two sides of the cam (2) are in contact with the push rod (1) and an elastic piece (3), respectively, and the cam (2) is pushed to rotate by rotating the push rod (1). Rotation of the cam (2) can press down and lock the elastic piece (3), and a locking wire hole of the elastic piece (3) is completely opened. By rotating the push rod (1) toward the other direction and pushing the cam (2) to release the elastic piece (3), the locking wire hole of the elastic piece (3) is locked. The mechanism is used to solve the technical problem of causing injury to a person due to a rebound instant impact being too large.
