摘要： An indication of a type of circuit breaker through which a powered device is connected to a power source is received at a processor. A signal from a sensor indicating a level of power flow from the power source to the powered device is received at the processor. The power flow to the powered device is altered by the processor based upon the received signal and the type of circuit breaker such that the power flow does not cause the circuit breaker to interrupt the power flow to the powered device.

摘要： A method and apparatus includes a monitor in communication with, e.g., a work glove with built-in sensors to track an operator's physical activities including intermittently using hand tools, hand motion, and position or location in a work area. The sensors provide time-series data representative of the activities, and the monitor classifies and sequences the activities based on the time-series data along with, optionally, machine tool operational data. The classified and sequenced activities may then compared to instructed work procedures, ensuring correct work materials are used in production, and ensuring an operator's safety by detecting unsafe or abnormal work conditions.

摘要： Apparatus and methods associated with operating a plasma torch are disclosed. According to some implementations, the apparatus and methods involve the delivery of a process gas to a shuttle valve at first and second pressures for the purpose of altering an axial position of a valve element located inside the shuttle valve. The shuttle valve is configured such that at different axial positions of the valve element the flow of process gas into the plasma torch is altered.

摘要： A wire feeder for a welding system has an automatically generated clamping force on welding wire. The wire feeder includes a drivestand having a lower feed roll. An upper feed roll is positionable adjacent to the lower roll, the upper and lower rolls being configured to receive a wire therebetween. A motor includes an output motor shaft, the lower roll being connected to the output motor shaft. A connecting arm is attached to the upper roll, and attached to the drivestand at a first end. An arm is attached to the connecting arm at a second end, and coupled to the motor. The arm and the connecting arm draw the upper roll towards the lower roll in response to a torque applied by the motor, such that the upper and lower rolls generate a clamping force for the wire, the clamping force being proportional to a torque of the motor.

摘要： Provided herein is a quick disconnect torch handle (12) for use in a plasma arc system (1). In one approach, the plasma arc system (1) includes a lead (6) having a first end (3) connected to a power source (2) and a second end (7) connected to a torch handle (12). The quick disconnect (16) is located at a proximal end (22) of the torch handle (12), and may include at least one signal connection, a pilot connection, a fluid connection, and a main power connection. The fluid and main power connection may be formed by a connection between a main power socket (37) and a conductive conduit (33). Specifically, the main power socket (37) includes a conductive spring (40) and an O-ring (41) encircling an interior bore (42) thereof. Removal of the conductive conduit (33) from the main power socket (37) causes the fluid connection to break between the O-ring (41) and the conductive conduit (33), and then the main power connection to break between the conductive spring (40) and the conductive conduit (33).
