Abstract
An object that is ordinarily held within a receptacle, such as a pen, is monitored to sense removal of the object from the receptacle. Removal of the object initiates a timing cycle. At the conclusion of the timing cycle, an alarm sounds unless the object has been replaced. A reset switch can be provided to reinitiate the timing cycle at any time. If desired, a plurality of object can be monitored, such that removal of any one object begins the timing cycle that leads to the alarm, and termination of the alarm or timing cycle requires replacement of all of the objects.
