Abstract: An electrical circuit to minimize the damage to internal electronics in the event of a lightning strike or power surge that may flow into the unit through the home run cable used to supply power to device loads, for example load cells and weigh terminals. The circuitry can not only protect, but it can also detect and distinguish from several overvoltage and undervoltage conditions that can occur.

Abstract: A keyboard structure is recessed within an open-topped base housing portion of a compact portable computer such as a notebook or laptop computer. Front comer portions of the keyboard structure are secured to the base housing in a manner permitting the keyboard structure to be pivoted relative to the base housing between a storage/transport orientation in which the top side of the keyboard structure is generally parallel to the bottom side of the base housing, a tilted use orientation in which the top side of the keyboard structure slopes forwardly and downwardly toward the user and an access position which allows easy access to the interior portion of the computer for making modifications to a mother board that has been positioned in the upper interior portion of the base housing. A resilient latch assembly has cooperable detent structures that are disposed on the keyboard structure and the base housing. The detent structures are easily detachable from themselves and also functions to prevent the keyboard structure from moving downwardly past the storage/transport position.
