  • Publication number: 20230046255
    Abstract: Methods and system for privacy preserving information exchange in a network of electronic devices are disclosed. In one embodiment, a method is implemented in an electronic device to serve as a local party for information exchange between the local party and another electronic device to serve as an aggregator. The method includes storing a plurality of values in a 2D vector, where a first dimension of the 2D vector is based on the number of values, and where each position in the first dimension has one unique value. The method further includes transmitting the 2D vector to the aggregator with masking for the aggregator to prevent the aggregator from decoding the 2D vector, where aggregating the masked 2D vector with masked 2D vectors from other local parties allows decoding of the aggregated 2D vector.

  • Publication number: 20220392893
    Abstract: Two approaches for on-chip ESD detection include variable dielectric width capacitor, and vertical metal-oxide-semiconductor (MOS) capacitor MOSCAP array. The variable dielectric width capacitor approach employs metal plates terminated with sharp corners to enhance local electric field and facilitate ready breakdown of a thin dielectric between the metal plates. The vertical MOSCAP array is composed of a capacitor array connected in series. Both approaches are incorporated in an example 22 nm fully depleted silicon-on-insulator. Vertical MOSCAP arrays detect ESD events starting from about 6 V with about 6 V granularity, while the variable dielectric width capacitor is suitable for detection of high ESD voltage from about 40 V and above.

    Abstract: A system and method for the reduction of NOx and CO contaminants using an ion-exchange resin media having lower-valency ions of the transitional metal elements, such as ferrous ions, cuprous ions and/or manganese ions, such that gases containing NOx and/or CO contaminants may be passed over the media so that the contaminants are absorbed by the lower-valency ions of the transitional metal elements, the media configured so that it can be regenerated to remove the NOx and/or CO contaminants. Regeneration includes exposing the media to a heated stream of hydrogen gas or exposing the media to hydrogen ions in an electrochemical cell.
