  • Publication number: 20240079784
    Abstract: An electronic device may be provided with an antenna having a resonating element and a light source module mounted to a flexible printed circuit and a metal cowling. The module may emit light through a rear housing wall. The printed circuit may be interposed between the metal cowling and a conductive support plate in the rear housing wall. The printed circuit may include a ground trace coupled to the resonating element. A dimpled pad may couple the ground trace to the support plate. Compressive foam may be used to exert a force against the flexible printed circuit that presses the dimpled pad against the conductive support plate. The ground trace and the dimpled pad may form a return path to ground for the resonating element. The dimpled pad may occupy less height within the device than other structures such as metal springs.

  • Publication number: 20200012939
    Abstract: A neural network may be trained on a training corpus that comprises a large number of dataset-visualization pairs. Each pair in the training corpus may consist of a dataset and a visualization of the dataset. The visualization may be a chart, plot or diagram. In each dataset-visualization pair in the training corpus, the visualization may be created by a human making design choices. The neural network may be trained to predict, for a given dataset, a visualization that a human would create to represent the given dataset. During training, features and design choices may be extracted from the dataset and visualization, respectively, in each dataset-visualization pair in the training corpus. After the neural network is trained, features may be extracted from a new dataset, and the trained neural network may predict design choices that a human would make to create a visualization that represents the new dataset.

  • Publication number: 20150303172
    Abstract: Reconstitution techniques for semiconductor packages are provided. One reconstitution technique is used to encapsulate a plurality of semiconductor packages into a single multi-chip module. Solder balls coupled to each package may be partially exposed after reconstitution, which enables the packages to be coupled to another device. Another reconstitution technique is used to couple a plurality of semiconductor packages into a package-on-package module using self-alignment feature(s). The self-alignment feature(s) are exposed solder ball(s) that are included in the bottom package of the package-on-package module. The exposed solder ball(s) serve as a frame of reference to other solder balls that are encapsulated by an encapsulation material. After the location of these other solders balls are determined, through-mold vias may be formed in the encapsulation material at locations corresponding to the other solder balls.

  • Publication number: 20060172245
    Abstract: A gas burner with thermoelectric unit installed inside the burner head to generate electricity with waste heat energy. Gas flame at the edge of the burner head creates high temperature source (hot side) for the thermoelectric unit. A heat sink is installed inside the burner head and cooled by the fuel mixture. Electricity is generated by the thermoelectric unit when the gas burner is in operation. The electricity generated by the thermoelectric unit can be used to power electric devices.

  • Publication number: 20060016446
    Abstract: A gas burner generates electricity with waste heat energy. At least one thermoelectric unit is installed underneath the burner cap of the gas burner. Gas flame at the edge of the burner cap creates heat sources (hot side) for the thermoelectric unit. A gas-mixing chamber underneath the thermoelectric unit functions as heat sinks (cold side) for the thermoelectric unit. An insulation plate is inserted in between the thermoelectric unit and the burner cap to control the hot side temperature. The thermoelectric unit generates electricity while the gas burner is in use and the flame heats up the burner cap. The thermoelectric unit connects to an electric circuit and provides electricity to power devices such as electric fans, lights, TVs, battery chargers etc.

  • Patent number: 5822503
    Abstract: Disclosed is a method of modifying one or more colors contained in an Encapsulated PostScript (EPS) file in a computer program such as a desktop publishing program (50). After an EPS file has been imported into a publication, all identifiable colors in the EPS file, i.e., spot colors and, in some instances, process colors, are displayed to a color palette (84). The color palette allows a user to see those colors (or inks) that are needed to print the publication, and subsequently modify the colors without having to return to the originating program that exported the EPS file. The method includes creating a publication color list that contains those colors that have been modified, generating a PostScript (PS) color table from the publication color list after the modifications are complete, and changing the attributes of those colors in the PS table while printing the publication to a file or to a printer.
