Earthquake detector is a solid-state device that detects the motion of a building or structure and initiates an alarm when the motion of a building or structure rises above a certain base level or threshold level of motion that is automatically calibrated or manually entered for the specific building or structure and the specific location of the building or structure. Earthquake detector measures the amplitude of movement and the magnitude of acceleration of the actual building or structure caused by a seismic event, earthquake, or other external force because this is the primary cause of damage to the building or structure and the associated potential for collapse of the building or structure. Earthquake detector has a circuit board; a microprocessor, integrated circuit, or chip; an accelerometer integrated circuit or chip; an alarm module; a connection to a power source; and a calibration control.

The coin display apparatus and method described herein includes rotatable hangers suspended from a trackway for displaying and positioning coins. In general, the coin display apparatus includes a rotatable hanger, a tab for attaching a coin to the rotatable hanger, and a trackway for suspending the hanger/coin arrangement. The coin is positionable along the trackway by sliding the rotatable hanger up and down the trackway to a desired location. In addition, the rotatable hanger includes a swivel arrangement such that the coin may be rotated individually around a longitudinal axis of the rotatable hanger so that the front or back of the coin may be displayed. This allows great flexibility in arranging the coins within the coin display apparatus such that symmetrical spacing is preserved, regardless of the number of coin in the collection. The coin display method includes using the coin display apparatus to display and position coins.
