Abstract
An apparatus, method and computer program is described including: a driver for driving a membrane of a gas-retaining chamber to induce vibrations in the membrane in a first mode of operation, wherein said membrane is configured to surround at least part of a device; and an activator for activating a rapid expander in a second mode of operation, wherein the expander comprises an expandable foam that is configured to inflate said chamber in response to an activation signal.
Claims15
An apparatus, comprising:
- a gas-retaining chamber having a membrane, said chamber configured to surround at least part of a device in use;
- an expander comprising an expandable foam that is configured to inflate said chamber in response to an activation signal;
- a driver for driving the membrane to induce vibrations in the membrane in a first mode of operation;
- and
- an activator for activating said expander in a second mode of operation.
A method, comprising:
- driving a membrane of a gas-retaining chamber to induce vibrations in the membrane in a first mode of operation, wherein said membrane is configured to surround at least part of a device;
- and
- activating an expander in a second mode of operation, wherein the expander comprises an expandable foam that is configured to inflate said chamber in response to an activation signal.
A non-transitory computer program storage device readable with an apparatus, tangibly embodying a program of instructions executable with the apparatus to perform at least the following:
- driving a membrane of a gas-retaining chamber to induce vibrations in the membrane in a first mode of operation, wherein said membrane is configured to surround at least part of a device;
- and
- activating an expander in a second mode of operation, wherein the expander comprises an expandable foam that is configured to inflate said chamber in response to an activation signal.
