Abstract
A centrifugally activated electronic device without an external switch. The electronic device includes an activation circuit, a power source, and electronic components sealed within a housing. The activation circuit includes a pair of centrifugal switches on opposite sides of the housing, which are closed by rapidly rotating the device housing, to complete the activation circuit and thereby turn on at least one of the electronic components. The electronic components include a power switch component that can be turned on by energizing the activation circuit and turned off manually via a powered, buttonless user interface, such as a graphical touch screen, and/or automatically when the electronic components detect a shutoff condition.
Claims17
A centrifugally activated electronic device comprising
- a housing, the housing enclosing and sealing an internal volume;
- an activation circuit disposed in the internal volume of the housing;
- a power circuit disposed in the internal volume of the housing, the power circuit including electronic componentry;
- a power source connected to the activation circuit and to the power circuit;
- the power circuit including electronic componentry;
- the activation circuit including a power circuit actuator, the power circuit actuator being operative, when energized, to cause the power circuit to become energized by the power source and to remain energized by the power source after the activation circuit is deenergized;
- the activation circuit including two or more centrifugal switches, the centrifugal switches being configured to close when the device is rotated at a rotational activation speed about an operative axis of rotation, the activation circuit being adapted and configured to be energized by the power source when the centrifugal switches are closed.
