Abstract:
A method of forming a compressible contact structure on a semi-conductor chip which comprises bonding a compressible polymer layer to the chip's surface, forming a plurality of openings within the layer, depositing electrically conductive material within the openings to form electrical connections with the chip's contacts, forming a plurality of electrically conductive line elements on the polymer layer extending from a respective opening and each including an end portion, and forming a plurality of contact members each on a respective one of the line segment end portions. The compressible polymer layer allows the contact members to deflect toward (compress) the chip when the contact members are engaged by an external force or forces. A semi-conductor chip including such a compressible contact structure is also provided.
Abstract:
A method and system for tracking goods, etc., food products, which involves identifying the received goods at a specified location and thereafter assigning an encoded readable code to each of the goods which can be only accessed by authorized personnel responsible for handling the goods on through to and including shipment, e.g., to customers. A host computer includes a database for encoding received identification data and thereafter encoding same to provide the readable codes. The method and system also allows the customer/recipient to access the codes to discern whether he/she has received the correct goods he purchased.
Abstract:
A data archiving and accessing system. The system comprises a client and a server. The client uploads transaction data and a public key. The server further comprises a database storing the transaction data and a transaction system. The transaction system implements authentication and authorization processes on the client, receives the transaction data with a public key via a transmission medium, encrypts the transaction data using the public key, associates and collocates the encrypted transaction data according to predefined tags, and stores the encrypted transaction data in the database
Abstract:
An interposer comprising at least two dielectric layers bonded to each other, sandwiching a plurality of conductors there-between. The conductors each electrically couple a respective pair of opposed electrical contacts formed within and protruding from openings with the dielectric layers. The interposer is ideally suited for use as part of a test apparatus to interconnect highly dense patterns of solder ball contacts of a semiconductor chip to lesser dense arrays of contacts on the apparatus's printed circuit board. The interposer is also capable of being used for other purposes, including as an interconnecting circuitized substrate between a semiconductor chip and a chip carrier substrate or between a chip carrier and a printed circuit board. Various methods of making such an interposer are also provided.
Abstract:
An optoelectronic assembly for an electronic system includes a thermally conductive, metallized transparent substrate having a first surface and an opposite second surface. A support chip set is bonded to the second surface of the transparent substrate. A first substrate is in communication with the transparent substrate via the metallized second surface and support chip set therebetween. A second substrate is in communication with the second surface of the first substrate and is configured for mounting at least one of data processing, data switching and data storage chips. An optoelectronic transducer is in signal communication with the support chip set, and an optical signaling medium having one end with an optical fiber array aligned with the transducer is substantially normal to the first surface of the transparent substrate. The support chip set and the transducer share a common thermal path for cooling.
Abstract:
A radio frequency (RF) device (or “tag”) for containing specific information relating to a particular good being shipped from one location (e.g., warehouse) to another (e.g., customer). The device includes a circuitized substrate (e.g., a printed circuit board), a semiconductor chip, an antenna and a power regulator, and is designed in one embodiment to be partly inserted within a good (e.g., a cardboard box) containing one or more of the goods being shipped and tracked. Alternatively, the device may be attached by other means (e.g., adhesive). A shipper can simply track the goods containing such devices using wireless communication devices (e.g., satellites) to quickly and readily ascertain the specific location of the goods at any time as well as the appropriate desired information relating to such goods (e.g., quantity, weight, type, etc.).
Abstract:
A device for expressing robot autonomous emotions comprises: a sensing unit; a user emotion recognition unit, recognizing current user emotional states after receiving sensed information from the sensing unit, and calculating user emotional strengths based on the current user emotional states; a robot emotion generation unit, generating robot emotional states based on the user emotional strengths; a behavior fusion unit, calculating a plurality of output behavior weights by a fuzzy-neuro network based on the user emotional strengths and a rule table; and a robot reaction unit, expressing a robot emotional behavior based on the output behavior weights and the robot emotional states.
Abstract:
A method of making circuitized substrate comprised of at least one dielectric material having an electrically conductive pattern thereon. At least part of the pattern is used as the first layer of an organic memory device which further includes at least a second dielectric layer over the pattern and a second pattern aligned with respect to the lower part for achieving several points of contact to thus form the device.
Abstract:
A system for monitoring traffic across a structure. A fiber Bragg grating (FBG) reflects a light wavelength. A mounting mechanism connects the FBG to the structure, such that physical change of the structure changes a stress to the FBG that changes the light wavelength. And optical fiber carries a first light beam to the FBG and carries a second light beam from the FGB. This permits first light beam including the light wavelength to be received from a light source, and permits the first light beam to be altered into the second light beam by passing the light wavelength through the FBG, and permits the second light beam to be provided to a detector to sense the light wavelength present in the second light beam. From this the stress in the structure and information about the traffic across a structure can be inferred.
Abstract:
A method of forming a capacitive substrate in which at least one capacitive dielectric layer of material is screen or ink jet printed onto a conductor and the substrate is thereafter processed further, including the addition of thru-holes to couple selected elements within the substrate to form at least two capacitors as internal elements of the substrate. Photoimageable material is used to facilitate positioning of the capacitive dielectric being printed. The capacitive substrate may be incorporated within a larger circuitized substrate, e.g., to form an electrical assembly. A method of making an information handling system including such substrates is also provided.
