Abstract:
A process for forming a laminate with capacitance and the laminate formed thereby. The process includes the steps of providing a substrate and laminating a conductive foil on the substrate wherein the foil has a dielectric. A conductive layer is formed on the dielectric. The conductive foil is treated to electrically isolate a region of conductive foil containing the conductive layer from additional conductive foil. A cathodic conductive couple is made between the conductive layer and a cathode trace and an anodic conductive couple is made between the conductive foil and an anode trace.
Abstract:
Touch sensors with one or more piezoelectric elements and devices containing such touch sensors are presented. The touch sensor contains keys that are independently actuated. Contact with a key provides tactile feedback through the piezoelectric element to the user. Each key provides an individual tactile feedback pattern that is dependent on the particular key contacted as well as the function of the key at the time of contact. Actuation of the key provides a different tactile feedback pattern. The piezoelectric element is bonded directly to a printed circuit board, on which electronic components are also mounted.
Abstract:
A device and method of background substitution are disclosed. One or more cameras in a mobile device obtain a depth image. A processor in or external to the device segments the foreground from the background of the image. The original background is removed and a stored background image or video is substituted in place of the original background. The substituted background is altered dependent on the attitude and motion of the device, which is sensed by one or more sensors in the device. A portion of the stored background selected as the substitute background varies in correspondence with the device movement.

Abstract:
A method for forming closed vies In a mgtfflayßr printed circuit board. A dielectric layer Is laminated to one side of a central. core having a metal layer on each side. A second dielectric layer is laminated to the other side of the central core. Closed vtas In the central core have been formed by drilling partially through but not completely penetrating the central core, and then completing the via from the opposite side with a hole that Is much smaller In diameter to form a pathway that penetrates completely through the central core from one side to another. The via is then plated with metal to substantially close the smaller hols. Approximately one half of the closed vlas are situated such that the closed aperture faces one dielectric layer and a remainder of the dosed vias are situated such that the closed aperture faces the other dielectric layer.
Abstract:
A method for forming embedded capacitors on a printed circuit board is disclosed. The capacitor is formed on the printed circuit board by a depositing a first dielectric layer over one or more electrodes situated on the PCB. Another electrode is formed on top of the first dielectric layer and a second dielectric layer is deposited on top of that electrode. A third electrode is formed on top of the second dielectric layer. The two dielectric layers are abrasively delineated in a single step by a method such as sand blasting to define portions of the first and second dielectric layers to create a multilayer capacitive structure.
Abstract:
A method is for fabricating an embedded capacitance printed circuit board assembly (400, 1100). The embedded capacitance printed circuit board assembly includes two embedded capacitance structures (110). Each capacitance structure (110) includes a crystallized dielectric oxide layer (115) sandwiched between an outer electrode layer (120) and an inner electrode layer (125) in which the two inner electrode layers are electrically connected together. A rivet via (1315) and a stacked via (1110) formed from a button via (910) and a stacked blind via (1111) may be used to electrically connect the two inner electrode layers together. A spindle via (525) may be formed through the inner and outer layers. The multi-layer printed circuit board may be formed from a capacitive laminate (100) that includes two capacitance structures.
Abstract:
Embedded capacitors comprise a bimetal foil (500) that includes a first copper layer (205) and an aluminum layer (210) on the first copper layer. The aluminum layer has a smooth side adjacent the first copper layer and a high surface area textured side (215) opposite the first copper layer. The bimetal foil further includes an aluminum oxide layer (305) on the high surface area textured side of the aluminum layer, a conductive polymer layer (420) on the aluminum oxide layer, and a second copper layer (535) overlying the aluminum oxide layer. The bimetal foil may be embedded in a circuit board (700) to form high value embedded capacitors.
Abstract:
A method of presenting content from a remote device is provided. Limited bandwidth content, transmitted from a remote device, is received at a local device. The limited bandwidth content is superimposed on enhanced content retrieved by the local device. The limited bandwidth content overlaps with the enhanced content such that the limited bandwidth content is a subset of what is represented by the enhanced content. The limited bandwidth or enhanced content may either be still images or video that is stitched together and displayed at the local device.
