An imaging apparatus includes an imaging unit that photoelectrically converts an object image to generate image data; a face detecting unit that detects a face in the generated image data; and a number-of-people detecting unit that detects the number of faces detected in the image data based on a face detection result by the face detecting unit. A pole is connected to the base member and extends vertically therefrom. The cantilever is useful in Scanning Probe Microscopes and other force-measuring devices, such as the Atomic Force Microscope, the Friction Force Microscope, and in probe attachments for the Surface Forces Apparatus where both normal and lateral forces acting on a tip need to be accurately, and unambiguously measured. In one embodiment a microwave energy source operates at a frequency to extend beyond the thermal conduction depth, or to penetrate the cryogenic ice ball and be absorbed in tissue beyond an ice boundary, thus extending the depth andor width of a single treatment locus. The hidden bonus feature does not affect the outcome of the play of the casino game.
