Abstract: A toy truck having a crane arm, comprising multiple telescopic components to form a crane extension mechanism. The crane arm extension mechanism includes a crane arm that is capable of telescopically extending based on the air pressure manually provided to fill telescopic members of the crane arm. To telescopically extend the crane arm, a crank is rotated which causes an air pump to pump air into the crane arm. As the air pressure in the crane arm increases, the crane arm telescopically extends.

Abstract: A music playing device for symphonic compositions allows a user to selective locate one or more musical instrument playing pieces within an orchestral pit and to listen to the series of notes of those instruments placed into the pit. The additive and subtractive benefits of musical instruments are thus appreciated. The device comprises a main base and individual, preferably, three dimensional musical instruments as playing pieces. Multiple symphonic musical compositions are available to be played with only the notes of those instruments being heard if and when placed into the pit area.

Abstract: The present invention relates to a data transmission/receiving method and apparatus for overcoming interference between multiple data streams, by relaying only part of multiple data streams that are received from a source node during collaborative data transmission employing relay nodes. The multiple data stream transmission method of the present invention comprises: receiving a plurality of data streams from a source node; decoding the plurality of data streams received; selecting a portion of the successful decoded data streams; encoding the selected portion of the data streams; and sending the encoded data stream portion to a destination node.

Abstract: The invention provides a novel adjustable mattress and pillow system and related methods in which a sensing mat positioned on the top face of a mattress affects microprocessor-controlled optimization of the contour of the mattress and a pillow based on a user's position. In one embodiment, the novel adjustable mattress and pillow system of the invention provides real time contour optimization through use of a variety of sensing techniques that make the system particularly useful in environments such as hospital critical care facilities where proper positioning of a user on a mattress and a pillow may prove important to user's health.
