An assembly includes a cabinet having an interior and a door to gain access to the interior. An intelligent electronic device (IED) is within the interior of the cabinet and includes inputs providing electrical connections to the IED, pushbuttons to provide user input to the IED, a display module including a display, a component, and a timer circuit. The timer circuit powers the component OFF or places it in a reduced power state when not in use after a certain amount of time. A switch is associated with the door and is electrically connected to at least one of the inputs so that when the display module is powered OFF or in the reduced power state and when the door is opened, the switch causes a signal to be sent to the timer circuit to cause the timer circuit to power the component fully ON.

Intelligent electronic device with powering options for the display when not in use

A method for making a high-power fused collimator, and a fused collimator made thereby, are provided. A fused collimator is provided that includes an end of a stripped end portion of an optical fiber fused to a proximal face of a silica lens. In an embodiment, a joint formed by the fiber end and the silica lens proximal face is substantially surrounded with a solder glass in a melted form. A cross-sectional area of the solder glass decreases proximally from a distal edge adjacent the lens to a proximal edge located along the fiber's stripped end portion. The solder glass is permitted to harden, forming a fused collimator. In another embodiment, a ferrule surrounds the fiber stripped end portion, and an adhesive is applied to the ferrule's proximal face to surround the fiber. The lens-ferrule joint is surrounded with solder glass, which is then surrounded with a silica sleeve.

High-power fused collimator and associated methods

A method for making a high-power fused collimator, and a fused collimator made thereby, are provided. A fused collimator is provided that includes an end of a stripped end portion of an optical fiber fused to a proximal face of a silica lens. In an embodiment, a toroidal element is positioned in surrounding relation to the fiber's stripped end portion, and a joint formed by the fiber end and the toroidal element proximal face is substantially surrounded with a solder glass in a melted form. A cross-sectional area of the solder glass decreases proximally from a distal edge adjacent the lens to a proximal edge located along the fiber's stripped end portion. Then the solder glass is permitted to harden, forming a fused collimator.
