  • Patent number: 11416664
    Abstract: The present description relates to a method based on artificial intelligence to implement a wide range of microelectronic circuits that can adapt by themselves to the usage conditions (e.g. loading changes), manufacturing variances or defects (e.g. process variations, device parameter mismatches, device model inaccuracies or changes, etc.), as well as environmental conditions (e.g. voltage, temperature, interference) in order to negate all or part of their effects on the circuit performance characteristics and achieve a very tight set of specifications over the wide range of conditions. Each microelectronic circuit is represented by a neural network model whose behavior is a function of the actual input signals, the usage and environmental conditions.

  • Patent number: 9092096
    Abstract: 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.

    Abstract: Provided are a method, computer program product, and system for a dynamic subscription update for multiple queue event systems. A subscription request, including one or more conditions is received. A first subscription object, containing the one or more conditions in the subscription request, is selected from a first set of subscription objects. The first subscription object is moved to a second set of subscription objects. A second subscription object is generated based on the first subscription object. The second subscription object is updated with a generated subscription version and the subscription request. The second subscription object is added to the first set of subscription objects. In response to receiving the one or more conditions, a first event is generated using the second subscription object. The first event including the generated subscription version and the one of more conditions. The first event is added to a collection of first events.

  • Publication number: 20120052929
    Abstract: 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.

  • Publication number: 20110018556
    Abstract: 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.

  • Publication number: 20110021108
    Abstract: 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.

  • Publication number: 20110021109
    Abstract: 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.

  • Patent number: 6999966
    Abstract: 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.

  • Patent number: 6938050
    Abstract: A content management system is provided including a plurality of tables forming a tree-based hierarchy for storing information such as item information. An information retrieval interface is provided to facilitate retrieval of information from the tree-based table hierarchy. The number of cursors employed for retrieving information is dynamically variable with the number of tables in the hierarchy. Advantageously, the content management system permits tables to be added or appended to the initial tree-based table hierarchy after the database is created. The number of cursors is dynamically varied to accommodate the additional cursors needed to query the additional table or tables.
