A content management system is provided including a plurality of tables forming a tree-based storage hierarchy. The system includes a stored procedure which enables information to be retrieved from different arbitrary locations throughout the storage hierarchy. Advantageously, the system retrieves information from both simple and complex tree-based storage hierarchies.

A content management system is provided including a plurality of tables forming a tree-based storage hierarchy. The system includes a library server having a stored procedure which creates a hierarchical tree-based storage structure having any number of child components horizontally and any number of component types vertically thus specifying a tree topology. Advantageously, a single invocation of the stored procedure will create the specified tree-based data storage structure which is stored in the library server.

A capacitive sensor comprises patterned electrodes and printed wires of conductive material integrated with sensing circuits on flexible circuit substrates. The flexible circuit substrates are fingered or otherwise elongated to distribute sensing points to the limbs in a toy doll or animal, or squares on a board game. Such sensing points can detect the presence of a finger even though actual contact is not made by measuring the proportions and changes in stray capacitance attaching to the various electrodes. Touch sensors are therefore possible even when the capacitor sensor's sensing points are covered by a doll's plastic skin or a plush animal's fur. Including an interlayer of open cell foam under the flexible circuit substrate further implements a pressure sensor because applied pressures will deform the geometries of the capacitor electrodes and dielectrics enough to produce a measurable change in capacitance.

Toy design methods break down the desired behavior of an electro-mechanical toy into unique states represented with electronics and/or mechanical modeling. The toy will exist in such rest state until some external event acts to trigger a state change in one or more of the parts. Any event can be defined at an appropriate user, environmental, or sensory input to can act as a trigger for the toy to react with some predefined behavior. Each of several physical toy states can be uniquely represented with an electronic circuit register. A multi-bit register status at any one particular instant directly represents the entire state the toy is in, and is quick and simple to inspect and act on. State changes triggered by input stimuli cause a change in the register bits reflecting the changing conditions of the toy.

A toy and software application accessory extends the distinguishing play experience of a particular toy to a digital play experience on personal digital assistant, personal navigation device, or other electronic device like an iPod or iphone with an accelerometer, speaker, and a touch-sensitive display screen. The software application accessory creates a digital play experience or video game on the electronic device that presents avatars, dialog, and backgrounds that convincingly accessorize the physical toy. Wireless connectivity to a PC and the Internet allows the toy or the electronic device to download updates, modifications, and enhancements to its basic program. New personalities can be downloaded that change the toy play experience, and extend the play life of the toy by introducing new and creative play experiences. A personality accessory kit includes the new personalities, clothes, props, and other matching accessories.

A capacitive touch sensor has a clear top plastic film and graphics or other designs disposed on its reverse side. Only the bare plastic substrate is exposed to the environment and user wear. Non-conductive color inks are used in printing the graphics so that any printed capacitive sensors in contact behind will not be short circuited or desensitized. A silk-screened base color layer with a print-free margin left all around its edges allows a later application of adhesive to grip a more durable surface underneath. Capacitive touch sensors are deposited on a bottom plastic film with silvered conductive inks. The printed capacitive sensors on film are fastened with a silk-screen applied liquid water-based adhesive and face the graphics printed side of the first plastic film. A final overcoat of adhesive is applied to the bare backside of the bottom plastic film for final assembly to a frame or chassis.

An interactive device has a plastic case for a mobile phone has graphics printed on the reverse side of a clear plastic film using non-conductive color inks. Electronic capacitive touch sensors are patterned and printed with conductive inks on a second plastic film in positions corresponding to individual graphic objects. A light guide layer is placed immediately beneath or above the pattern of printed electronic capacitive touch sensors. Diffusers on the top surface of the light guide layer catch light propagating and reflecting inside by refraction redirect it up to the user's eyes through openings in the non-conductive color ink graphics. The phone itself, a micro-controller, software, and associated electronic components mounted on a circuit board are used to control the lights sent into the light guide layer from its edges, and they control the response to touches being sensed by the touch sensors.

An improved method for routing interconnect lines in a VLSI chip using repeaters. First, an optimal virtual assignment of the repeater locations is determined according to a suitable method. The "virtual" assignment is the ideal location irrespective of where logic blocks which could form a repeater cell might located. Next, repeaters are assigned to physical locations close to the optimal virtual locations. Finally, an optimal global routing is done using the physical locations of the repeaters. The optimal global routing revises the original global routing upon which the original optimal virtual assignment of repeaters was done. Preferably, blocks of circuitry and routing channels are identified first. Instead of simply routing the interconnect lines through the channels, a portion of the interconnect lines are routed through available spaces in the blocks themselves. This will reduce the number of turns required both through the channels and to reach a repeater.
