Abstract: A device and system of information exchange for an educational toy is disclosed. Inside an external shell is placed a small computer. The Device interacts through auditory and visual responses, and accepts input through buttons, RFID accessories, smart cards and speech. The Device communicates with other like devices through a wireless Bluetooth connection. The Device receives information updates via a Bluetooth dongle that plugs into the end user's computer. When the Device is synchronized with the end user's computer, new information is pushed to (and stored in) the Device's internal computer. The end user's computer automatically downloads updates and configuration information from a central web server, via a background software application, which can be transferred during synchronization. Updates and configuration information are available via an online store hosted on the central server. The Device leverages the end user's smartphone to partially replace functionality performed by the internal computer.

Abstract: A transmission including two input members for independently driving an output member in a single direction. The direction of the output is reversible. One of the inputs may be a handle and another a motor in the handle.

Abstract: A transmission is provided which has unidirectional output rotation in response to multidirectional input rotation. A reversing member is provided for changing the direction of rotation of the output member. A first mechansim rotates the output member in a first direction in response to a first direction of rotation of the input member, and this first mechanism does not drive the output member in response to a second direction of rotation of the input member. A second mechanism rotates said output member in the first direction in response to the second direction of rotation of the input member, and this mechanism does not drive the output member in response to the first direction of rotation of the input member. The axis of rotation of the input member and the axis of rotation of the output member are coaxial.
