3526 results about "Torch" patented technology

A torch is a stick with combustible material at one end, which is ignited and used as a light source. Torches have been used throughout history, and are still used in processions, symbolic and religious events, and in juggling entertainment. In some countries "torch" in modern usage is the term for a battery-operated portable light.

Personalized interface for torch system and method

There is provided a system and method for quick identification and selection of torch processes based on a profile scheme. In an illustrated embodiment, a profile selectable via a one-click process may define operational parameters for one or more torch processes. Multiple profiles may be identified by corresponding labels that are visible on the face of the system. Furthermore, in an illustrated embodiment, the profiles and associated torch processes may be automatically stored in the system upon user configuration of the operational parameters. For example, in one embodiment, the user may select a profile and configure a welding process. Upon changing an operational parameter, it may be automatically saved to the selected profile and process. Reselection of that profile may recall the last used process and its associated parameters. The operational parameters of other configured processes may then be retrieved by selecting the desired process within the selected profile.
