Abstract
The present invention is a dual-mode alarm apparatus for sports equipment. The two modes of the alarm apparatus are a first motion detect mode and a second separation detect mode. In the first motion detect mode, the alarm can be triggered when the device is moved from a set initial position which could be any orientation. In the second separation detect mode, the alarm can be triggered by the disconnection of a tether cord that changes the position of a tether switch, to help the user to locate his sporting equipment. The alarm fits in a compact housing to fit neatly on the sporting equipment, with an accessible key switch and a flashing LED to indicate the system is armed. The electronic circuitry of the alarm apparatus is an effective and efficient combination of functional electronic components which carry out a fixed sequence of electrical signal events, electronically responding to trigger events with a realistic sensitivity level of response, with a workable time span between the electrical signal events.
