Abstract: An object is placed at a particular distance away from the nonreflecting side of a mirror, such that the gravitational force of the object affects the mirror. A laser is then pointed at the opposite, reflecting side of the mirror, thereby itself reflecting off the mirror and going back in to the cavity of the laser, creating a mode-hopping effect. The mirror will be affected by three forces, the force of a spring (FS), the force of a modulating signal (FMS), created by an electro mechanical device attached to the mirror, and the gravitational force of objects as they approach and recede away from the mirror.

Abstract: A combination dip and cake holder and punch bowl is readily configurable between any of three configurations. A platter member has a base with a female receiver, while a first type of receptacle has an extension that is receivable within the receiver so that when the first receptacle faces upwardly, a dip holder is formed. A second receptacle also has an extension that is receivable within the first extension of the first receptacle in order to form a punch bowl. When the first receptacle rests on its rim and the platter member receives the receptacle's extension, the device acts as a cake holder with the second receptacle being used as a cover that sits on the platter member.
