A method and apparatus for unlocking and remove at least one plug-in electrical or IoT device locked by two lock ramps included in two channel of ramps on two surfaces of the plug-in device engaging at least two reciprocal channel of ramps on two surfaces of a support box, by an insertable dual release bar attached to a pull cord or an handle of an hand tool for inserting two insertable bars between the channels of ramps and the reciprocal channels of ramps for unlock and pull to remove the plug-in device.

A manually operated disconnect maintains a machine/process in a de-energized state. The disconnect employs a sensor that automatically detects, via wireless communication, a lock affixed to the disconnect that locks the disconnect in an open state. Processing circuitry coupled to the sensor determines lockout tagout data, such as identification of a user associated with the lock, a time of application of the lock, and data identifying and/or locating the disconnect or a machine/process to which the disconnect provides power when in a closed state. Memory circuitry coupled to the processing circuitry stores the lockout tagout data, and holds it available for user review, transmission, analysis, reporting, and so forth.

A wall-mounted keypad may include a light detector circuit located inside the keypad that is configured to measure an ambient light level in a space. The light detector circuit may receive ambient light through an aperture that is hidden from view by the keypad. The keypad may include a reflector for directing ambient light onto the light detector circuit. The keypad may include an enclosure that houses the light detector circuit. The enclosure may define a recess that exposes at least a portion of the light detector circuit. The enclosure may include a reflector that may focus ambient light received through the aperture onto the light detector circuit. The keypad may include a control circuit that may be configured to illuminate the indicia of respective buttons of the control device in response to actuations of the one or more buttons, in accordance with the measured ambient light level.

A plurality of bidirectional optoports forming plurality of junctions for propagating optical signals two way through a plurality of optically cascaded chains linked to an electrical grid of building unit via intelligent support boxes and four way exchanges to include optical links to the electrical grid via plug-in electrical devices including IoTs and Ai devices and for providing traffic control to optical signals and the many well known other communication signals.

Apparatus, systems, and methods for determining a temperature excursion are provided. In one example, a system can comprise a temperature switch component that experiences a temperature excursion associated with a metal alloy of the temperature switch component and one or more electrodes, wherein the temperature excursion is based on a temperature of the metal alloy exceeding a defined threshold value. Additionally, the system can comprise a radio frequency identification tag component that receives a signal, from an external reader device, utilized to determine that the temperature excursion has occurred based on a parameter change, associated with the temperature excursion, from a first parameter to a second parameter different than the first parameter.
