Abstract
Pressure response devices, systems, and associated methods. The pressure response device includes a flange portion, a central portion, and an angled frustum portion provided between the flange portion and the central portion, with the angled frustum portion configured to activate upon experiencing a predetermined pressure differential. Pressure response systems may include a projection, a conductive arch, or a photo emitter configured to indicate a response to the predetermined pressure differential. Pressure response device may be a battery device, with the pressure response member configured to form part of an electrical conducting path until a predetermined pressure condition is reached.
Claims50
A pressure response device comprising:
- a flange portion;
- a central portion, the central portion having an inlet side and an outlet side;
- an angled frustum portion provided between the flange portion and the central portion;
- and
- wherein the angled frustum portion is configured to activate upon experiencing a predetermined pressure differential causing the movement of the central portion.
A pressure response system comprising:
- a pressure response device, the pressure response device including
- a flange portion,
- a central portion, and
- an angled frustum portion provided between the flange portion and the central portion;
- wherein the central portion is substantially flat;
- a projection, the projection being operably attached to the central portion;
- wherein the angled frustum portion is configured to activate without rupturing upon experiencing a predetermined pressure differential causing the movement of the central portion;
- and
- wherein the activation of the frustum portion causes the projection to indicate a pressure response.
A pressure response system comprising:
- a pressure response device, the pressure response device including
- a flange portion,
- a central portion, and
- an angled frustum portion provided between the flange portion and the central portion,
- wherein the angled frustum portion is configured to activate upon experiencing a predetermined pressure differential causing the movement of the central portion;
- a conductor, the conductor configured to make an electrical wire connection with the central portion before the angled frustum portion activates;
- and
- wherein the electrical wire connection is interrupted when the angled frustum portion activates.
A battery device comprising:
- an exterior contact terminal;
- a pressure response member positioned within the battery device, the pressure response member having a first configuration and a second configuration;
- the pressure response member including a central portion surrounded by an angled frustum portion;
- and
- wherein the pressure response member forms part of an electrical conducting path within the battery device in the first configuration and wherein upon experiencing a predetermined pressure condition with the battery device, the pressure response member achieves the second configuration and no longer forms part of an electrical conducting path within the battery device.
A method of testing a pressure response system comprising:
- providing a pressure response member including a flange portion, a central portion, and an angled frustum portion between the flange portion and the central portion;
- applying an increasing pressure differential to one surface of the central portion;
- and
- recording the pressure at which the angled frustum portion activates.
A method of responding to an overpressure situation, comprising:
- providing a pressure response member including a flange portion, a central portion, and an angled frustum portion between the flange portion and the central portion, wherein the pressure response member has a first configuration and a second configuration;
- exposing the pressure response member in the first configuration to a pressure source, such that the pressure response member responds to a predetermined pressure in the pressure source by taking the second configuration.
