Abstract
A welding protection device that includes a shield body, an automatic darkening filter insertable in the shield body, and a haptic sensing unit to sense a touch pattern occurring on the shield body or automatic darkening filter assembly. Upon sensing of a touch pattern, a user definable command is executed that can place the welding protection device in a specific operational state.
Claims16
A welding protection device, comprising:
- a shield body;
- an automatic darkening filter assembly insertable within the shield body and configured to enter into one or more different functional states, the automatic darkening filter assembly comprising a user interface that is inside the welding protection device when the automatic darkening filter assembly is inserted within the shield body;
- and
- a haptic sensing unit disposed within the welding protection device and configured to sense a touch pattern occurring on at least a first portion of the shield body or automatic darkening filter assembly such that a welder can tap anywhere on the first portion to switch functional states without the need for the welder to access and activate an external button on the welding protection device or the user interface inside the welding protection device.
A method of entering into a grinding mode for a welding protection device having a shield body and an automatic darkening filter assembly comprising a user interface that is inside the welding protection device when the automatic darkening filter assembly is inserted within the shield body, comprising:
- providing a haptic sensing unit within the welding protection device having a haptic sensor configured to sense a touch pattern occurring on at least a first portion of the shield body or automatic darkening filter assembly such that a welder can tap anywhere on the first portion to switch functional states without the need for the welder to access and activate an external button on the welding protection device or the user interface inside the welding protection device;
- executing a user definable command when the haptic sensor senses a touch pattern occurring anywhere on at least a first portion of shield body or automatic darkening filter assembly;
- and
- triggering a particular light state for the automatic darkening filter assembly based on the touch pattern sensed.
