  • Publication number: 20100250135
    Abstract: A method and device enables an efficient determination of a proximity of a social network service acquaintance. The method includes transmitting an inquiry message from the electronic device during a device proximity discovery process (step 405). An inquiry response message is then received in response to the inquiry message, where the inquiry response message includes a received social network service identifier associated with the social network service acquaintance (step 410). Next, a proximity of the social network service acquaintance is determined by matching the received social network service identifier with a stored social network service identifier (step 415). An output is then provided at the electronic device in response to matching the received social network service identifier (step 420).

  • Patent number: 7268661
    Abstract: A composite fuse element includes a network or matrix of conductive material that is in contact and interspersed with arc suppressing materials at a particle level. In such a matrix, the conductive (e.g., metal) network and the arc suppressing material particles provides a large contact surface area between these materials. When the conductive network melts or vaporizes, the resulting conductive vapors are adsorbed into the arc suppressing particles in a short time due to the large contact area between conductive and arc suppressing materials and the short diffusion distance that the conductive vapors are required to travel before they are absorbed by the arc suppressing material.

    Abstract: A dense lead-free glass ceramic that has low dielectric constant and low dielectric loss for producing high-frequency ceramic devices, such as inductors and low temperature co-fired ceramics (LTCC), is disclosed. The glass ceramic consists of 15-35% by weight of lead-free borosilicate glasses with low softening point, 15-35% by weight of lead-free borosilicate glasses with high softening point, 20-80% by weight of combination of amorphous and crystalline SiO2-filler (preferably 5-30% by weight of amorphous SiO2, 10-50% by weight of crystalline SiO2) and 0.1-10% by weight of at least one oxide of Al2O3, BaO, Sb2O3, V2O5, CoO, MgO, B2O3, Nb2O5, SrO and ZnO. The glass ceramic can be densified up to 99% of its theoretical density after firing and is co-firable with conductive metals between 800-900° C. The dense glass ceramic has dielectric constant of 4.2-4.6 and loss tangent (tan ?)<0.0025 at 20 MHz and good thermal/mechanical strength for application in high frequency electronic devices.

  • Patent number: 6602766
    Abstract: A multilayered electronic component with or without inter-layer connections created by a process using radiation curing such as ultraviolet/electron beam curing techniques. UV light or electron beam curable binders are mixed with ceramic powders and metals powders to form a ceramic slurry and electrode ink, there is little or no solvent in the metal ink and ceramic slurry. Instead of drying, a UV or electron beam is used for curing the binders. These binders could contain UV/electron beam curable monomers or oligomers, photo initiators, and other additives to provide the desired chemical and physical properties in the forming process.

  • Publication number: 20030024111
    Abstract: A multilayered electronic component with inter-layer connections is created by a process using dot penetration techniques. Electrodes are formed on a substrate. One or more conductive structures are formed on the electrodes to provide for interlayer electrical connections. A non-conductive (e.g., ceramic) sheet is laminated on top of the conductive dots under elevated pressure and temperature to cause the dot to penetrate through the ceramic sheet. A second electrode is printed on top of the penetrated conductive structure to complete the interlayer electrical connection without having to punch holes to form vias in the ceramic sheet.

  • Patent number: 6228230
    Abstract: An apparatus for electroplating small parts comprises an electroplating bath for holding an electrolyte and electroplating anodes. The apparatus includes a container having at least one screened parts compartment for holding the parts to be electroplated, and incorporates an electrically conductive screen as its base portion, on which the parts are settled. The conductive screen is adaptable to be connected to the negative pole of a power supply to function as the cathode. A pump circulates freshly ionized electrolyte into the parts compartment and directs a flow of the electrolyte to periodically tumble the parts in the parts compartment. Thereafter, the parts are shaken by a shaker to level the parts to maximize the surface and electrical contact between the parts and the screen when they are settled on the screen. In alternative embodiments of the invention, the container can be of perforated panel construction.
