Self-contained bistable information display with mechanical activation
A self-powered, self-contained, signage device includes a bistable display with its state-change power received from an actuator handle or pushbutton attached to a mechanically activated generator integral to the display. The device may be integrated into actuating members for various equipment types thereby providing a highly visible status indication of equipment operations.
1. A self-contained information display device, comprising:
a bistable display electrically attached to
an electrical generator mechanically powered by operation of an actuator for moving a portion of the generator,
whereby operation of the mechanically powered generator causes the bistable display to change state.
2. The information display device of claim 1 wherein the actuator of the generator is integral with one of a handle and a button.
3. The information display device of claim 2 wherein the one of a handle or button is integral with the operation of an associated apparatus, and the bistable display indicates a status of the associated apparatus.
4. The information display device of claim 1 wherein the bistable display changes state to give a status of operations of an electrical distribution device.
5. The information display device of claim 1 wherein the actuator is operated manually.
6. The information display device of claim 1 wherein the bistable display includes a display of “OFF” and a display of “ON.”
7. The information display device of claim 1 further comprising an electronic substrate carrying components for controlling information of the bistable display.
8. The information display device of claim 1 further comprising a power regulator for the bistable display.
9. The information display device of claim 8 wherein the power regulator is a microtransformer.
10. An actuator for a mechanically controlled apparatus, comprising:
a handle having a shaft portion and an annular handle portion at one end of the shaft portion,
a rotor portion of a generator attached to the annular handle portion, and
an annular stator for receiving the rotor,
whereby the rotor is movable with a motion of the handle.
11. The actuator for a mechanically controlled apparatus according to claim 10 , wherein the annular handle portion further contains an electronic substrate within the annular handle portion for carrying electronic components used in production or change of display signals.
12. An electrical distribution device comprising:
an enclosure,
a mechanical link from the outside of the enclosure to the inside of the enclosure for operation of a distribution device function,
an actuator on the outside of the enclosure attached to the mechanical link,
the actuator having integrated therein a bistable display device electrically attached to an electrical generator mechanically powered by operation of the actuator for moving the mechanical link, and
whereby operation of the mechanically powered generator causes the bistable display to change state.
