发明名称 Method for detecting motion of an electrical device or apparatus
摘要 A method for providing an alert to a person to unplug an electrical power cord of an electrical device or equipment includes an alarm device that is activated upon separation of a first portion from a second portion. The first and second portions of the alarm device are secured proximate opposite sides of a loop provided in the power cord. The first and second portions, when engaged, maintain a switch of an electrical circuit in an open position. If the equipment is moved prior to unplugging the power cord, the loop will be straightened, causing the first and second portions to separate. The switch closes, completing the electrical circuit and activating the alarm device. The alarm alerts the person to unplug the power cord. A first alternate method includes the alarm device as a part of newly manufactured equipment. A second alternate method includes a motion detector or sensor in the alarm device of the newly manufactured equipment. A third alternate method includes an add-on alarm device with the motion detector or sensor.
