Abstract: A teleconferencing system for voice and data provides interconnections among user sites via a central station. User stations at user sites each alternate operation between a data mode connecting a user computer and modem to a user telephone communication path and a voice mode connecting a telephony circuit to the communication path. The teleconferencing system is adapted for conducting a voice conference over standard telephone lines while allowing simultaneous viewing of data objects such as slides, graphs, or text. A host computer connected to the central station serves as a central repository for storage and retrieval of data objects for use in teleconferences.

Abstract: A transportable play design assembly with an open operative position, an alternative closed position and which may be folded to enclose play items therebetween when play time is concluded. The open operative position is utilized as a play surface. The alternative closed position is utilized as a transporting and storage device for play items. The alternative closed position further has a closing mechanism to prevent the play items from falling out of the assembly during transportation.

Abstract: A bathtub toy assembly including a play support platform assembly, a first flap pivotally connected to one end of the platform assembly and a second flap pivotally connected to an opposite end. With the flaps in horizontal positions, the bathtub toy assembly can be positioned across a bathtub, supported on opposite tub sides and with the platform assembly suspended over the tub in a child play position. The flaps can be re-positioned in vertical positions forming legs for supporting the toy assembly on a horizontal surface with the platform assembly raised. A child can then set on the horizontal surface with his legs underneath the platform assembly and play with toys on the platform assembly. Movable mechanistic play toys can be attached to the platform assembly and horizontal and vertical paths can be formed relative to the play toys and along which a child can move toy vehicles. The toy vehicles can each have a floatation device in its chassis allowing it to float upright and level in water.

Abstract: This invention is directed to a system capable of indicating to a user that a desired water temperature and/or the water level within a bathtub have been reached. The system includes a water sensor so that as the running water fills the bathtub, the system may activate an alarm if the water sensor detects the water at a predetermined level within the bathtub. This may assist in preventing the water within the bathtub from overflowing. The system may also include a temperature sensor to monitor the temperature of the water in the bathtub so that if the temperature of the water reaches a predetermined temperature, the system may sound an alarm as well. The system includes a transmitter that sends a signal to a receiver to notify to the user that the alarm has been activated. The receiver may be remote from the transmitter to allow the user to carry the receiver.
