Abstract
A power control circuit for use with devices that will be placed in a flammable sterilizing gas includes a bi-stable switch that is configured to produce an output to place the circuitry of a connected device in a run state or a sleep state. The bi-stable switch controls one or more transistors to drain energy from energy storage devices in the circuitry of the connected device to a level below an ignition level of a sterilizing gas. A remotely actuatable switch can be actuated from outside of a packaging in which the power control circuit is placed to cause the bi-stable switch to produce an output that puts the circuitry in the run state without removing the power control circuit from the packaging.
Claims19
A power control circuit for use with a device having circuitry that is configured to be powered by a power source and operate in a targeted environment, the power control circuit comprising:
- a switch connectable to the power source and configured to produce an output to transition the circuitry of the device between at least a run state and a sleep state;
- and
- at least one transistor connectable to one or more energy storage devices in the circuitry of the device, wherein the at least one transistor is configured to respond to the output of the switch and drain stored energy from the one or more energy storage devices to at least a sleep level associated with the targeted environment for operating the circuitry of the device in the sleep state.
A power control circuit configured to selectively place a device into a run state or a sleep state, the power control circuit comprising:
- a control circuit that is configured to generate a control signal that operates a connected device in the run state or the sleep state, wherein the control circuit is remotely controllable to place the connected device in the run state or the sleep state;
- and
- a transistor that is controlled by the output of the control circuit to drain stored energy from one or more energy storage devices of the connected device when the connected device is in the sleep state.
