Abstract: A toy system that can be used in a body of water. The system includes a plurality of toy accessories that can be placed in the water. Placement of a toy accessory into the water activates the accessory to generate a signal. The signal is received by a base station. The base station generates an output in response to the signal. By way of example, the base station can generate a speech pattern. Each toy accessory may provide a unique code to the base station. Each code may generate a different speech pattern.

Abstract: A combined optical imaging/display device employs a liquid crystal light valve (LCLV) with a charge coupled device (CCD) input, and a photosensitive CCD or charge injection device (CID) array for receiving an input image and developing a corresponding signal pattern. The signal pattern is applied as an input to the CCD after amplifying it and manipulating it as desired. The CCD and photosensitive array are provided on a common substrate; their cells may be arranged in alternating rows or in separate arrays. The invention is applicable to active vision enhancement goggles.
