METHOD AND APPARATUS FOR AUTHENTICATING AND DETECTING CIRCUIT BREAKER INTEGRITY

A circuit breaker apparatus may include a housing, a circuit inside the housing for protecting the conductors and the load of the circuit, a display attached to outside of the housing, a controller, and a power control device. The display may be an electronically-alterable display that does not require power in situations other than changing its state. The power control device may provide power to the controller and the display when the apparatus is being tampered with. When the controller is powered, it may cause the power control device to cause the display to change from a state that indicates that the apparatus is authenticated to another state that indicates that the apparatus has been tampered with. The power control device may include a battery and a switch, or a power harvester, which can be configured to provide power to the controller when the apparatus is being tampered with. 1. A circuit breaker apparatus comprising:a housing;a circuit disposed in the housing and configured to connect a power line to a load via one or more conductors and provide circuit protection for the one or more conductors and the load; the first state indicates that the apparatus is authenticated and the second state indicates that the apparatus has been tampered with, and', 'power is not required to maintain the first state or the second state once displayed;, 'a display that is operable to change from a first state to a second state, whereina controller; anda power control device electrically coupled to the controller; the display is configured to be in the first state when the apparatus is authenticated and has not been tampered with,', 'the power control device is configured to provide power to the controller when the apparatus is tampered with, and', 'the controller is configured to, when powered, send a signal to cause the display to change from the first state to the second state., 'wherein2. The apparatus of claim 1 , wherein the power control device comprises an energy ...

LUMINOUS KEYBOARD

A luminous keyboard includes at least one key, a switch circuit board, a supporting plate, a backlight module, a reflecting plate and a light-sheltering plate. The backlight module emits a light beam. The backlight module is arranged between the reflecting plate and the light-sheltering plate. A periphery region of the reflecting plate and a periphery region of the light-sheltering plate are thermally laminated or laser welded to define a sealed structure. Since the periphery region of the backlight module is sealed by the sealed structure, the light beam is not leaked out through the periphery region of the backlight module. The space occupied by the sealed structure is not very large. Consequently, the volume of the luminous keyboard is reduced. 1. A luminous keyboard , comprising:at least one key exposed outside the luminous keyboard;a switch circuit board located under the at least one key, wherein when the switch circuit board is triggered by the at least one key, a corresponding key signal is generated;a supporting plate located under the switch circuit board and connected with the at least one key;a backlight module located under the supporting plate, and generating a light beam and projecting the light beam to the at least one key;a reflecting plate disposed within the backlight module, wherein the light beam is reflected by the reflecting plate; anda light-sheltering plate arranged between the backlight plate and the supporting plate to shield the light beam, wherein a periphery region of the reflecting plate and a periphery region of the light-sheltering plate are thermally laminated or laser welded to define a sealed structure, so that the light beam is not leaked out through a periphery region of the backlight module.2. The luminous keyboard according to claim 1 , wherein the backlight module comprises:a light guide plate arrange between the light-sheltering plate and the reflecting plate to guide the light beam to the at least one key, wherein the light ...
