Abstract: A travel speed sensing system includes an optical sensor configured to be coupled to a welding torch. The optical sensor is configured to sense light incident on the optical sensor, and the travel speed sensing system is configured to determine a travel speed of the welding torch, a direction of the welding torch, or both, based on the sensed light.

Abstract: An example sheet product dispenser includes a housing for holding a new roll and a previously installed roll of sheet product. The dispenser includes a dispensing mechanism defining a nip and operable to dispense sheet product from either roll for retrieval by the user. A loading device of the dispenser is configured to receive a leading end of a new roll of sheet product being installed into the housing. The loading device can transition between three positions. In a receiving position, the loading device receives the leading end. In a nip loading position, the loading device causes the leading end to enter the nip to cause the dispensing mechanism to begin dispensing from the new roll. In a holding position, the loading device holds the leading end away from the nip to prevent dispensing from the new roll.

Abstract: Dual roll sheet product dispensers of a compact design are provided herein. A sheet product dispenser comprises a first roll holder for a first product roll and a second roll holder for a second product roll. A housing includes a base portion and a cover that is movable relative to the base portion to define an open position and a closed position. A chassis is mounted between the first roll holder and the second roll holder and movable between a retracted position and an extended position. The chassis is movable to the extended position when the cover is in the open position. The chassis includes a first dispensing mechanism and a second dispensing mechanism.

Abstract: A welding system includes a first sensor associated with a welding helmet and configured to sense a parameter indicative of a position of a welding torch relative to the welding helmet. The travel speed sensing system also includes a processing system communicatively coupled to the first sensor and configured to determine a position of the welding torch relative to a workpiece based on the sensed first parameter.

Abstract: A welding system monitors the changes in the power output provided from a power supply to a device to determine the inductance of power cables between the power supply and the device. The device may determine the inductance of the power cables based at least in part on a delay in a threshold change in voltage to the device after a change in the current demand of the device, a delay in the initialization of the change in the current demand of the device after an initialization signal, a rate of change of the current drawn by the device, or a relative comparison of the voltage to the device and the current drawn by the device, or any combination thereof. If the inductance of the power cables is greater than a threshold inductance, the device may signal the user, disable operation of the device, or any combination thereof.

Abstract: Some example product dispensers that accommodate two full paper towel rolls are provided herein. The product dispenser may employ separate dispensing mechanisms for each product roll and may include roll holders that articulate out from the housing to facilitate easy loading and access to replacement and loading of the other product roll. A roll partition may be utilized to separate the web paths of the two product rolls and enable rotation of front roll holders. Example funnel covers and nip covers can aid with intuitive installation. Example roll holders with retention mechanisms help prevent unintentional dropping of the installed product roll. Other beneficial features include utilizing motor operation sensing to dispense a desired sheet length, automatic/assisted loading into the dispensing mechanism, automatic switching between dispensing of product rolls, and always dispensing from the smaller product roll first. Many other features/structures of example product dispensers are also described herein.

Abstract: A main controller may be used to provide integrated, centralized, and optimized handling of telematics data in welding arrangements. The main controller may receive from other components of a welding arrangement, telematics data, and may apply at least some processing to the telematics data, to enable use of the telematics data by a remote entity. The telematics data may comprises data relating to an engine used in driving one or more components of the welding arrangement, data relating to one or more components of the welding arrangement, and/or data relating to welding operations performed via the welding arrangement. The processing of telematics data may comprise formatting data in accordance with a single standard format, digitizing analog data, and/or processing data for communication to the remote entity. The main controller may provide telematics client and/or host node functions, such as based on the controller area network (CANBus) protocol.
