Abstract: A cross-leg alert device comprising a cross-leg detector for detecting a cross-legged posture and an alert generator is disclosed. The alert generator is to generate an alert to a user upon the cross-leg detector detecting a change in posture from a non-cross-legged posture to a cross-legged posture. The cross-leg detector is for detecting a cross-legged posture and the alert generator is for generating an alert signal to a user when the cross-leg detector has detected a change in posture from a non-cross-legged posture to a cross-legged posture.

Abstract: A low-cost compact slide presentation toy offering combined slide projector and viewer function by integrating a slide projector section and a slide viewer section with a single housing. Both sections share a common slide recieving slot so that simulataneous viewing and projecting is made possible by means of a novel rotatable slide member which carries a plurality of image cells in a diametrically opposite manner. Also, images to be viewed or projected can be changed by simply rotating a slide member without the need of actually removing a slide from the device. This device is particular attractive for young children.
