  • Patent number: 11418759
    Abstract: In various embodiments, a group photograph system coordinates and creates a group photograph of participants of a video conferencing session. Using inputs from the participants, the group photograph system captures images of individual participants and selectively assembles a group photograph based on the rating of each individual participant. In one embodiment, the group photograph system sends a countdown signal to a first participant and a second participant wherein the first participant and the second participant are part of a group photograph within a video conferencing session wherein the countdown signal represents an amount of time before a first participant image is captured of the first participant. In another embodiment, the group photography system captures the first participant image and a second participant image of the first participant and the second participant, respectively and creates a first group photograph which includes the first participant image and the second participant image.

    Abstract: The present teaching generally relates to removing perturbations from predictive scoring. In one embodiment, data representing a plurality of events detected by a content provider may be received, the data indicating a time that a corresponding event occurred and whether the corresponding event was fraudulent. First category data may be generated by grouping each event into one of a number of categories, each category being associated with a range of times. A first measure of risk for each category may be determined, where the first measure of risk indicates a likelihood that a future event occurring at a future time is fraudulent. Second category data may be generated by processing the first category data and a second measure of risk for each category may be determined. Measure data representing the second measure of risk for each category and the range of times associated with that category may be stored.

  • Publication number: 20220246564
    Abstract: Structures and techniques provide bond enhancement in microelectronics by trapping contaminants and byproducts during bonding processes, and arresting cracks. Example bonding surfaces are provided with recesses, sinks, traps, or cavities to capture small particles and gaseous byproducts of bonding that would otherwise create detrimental voids between microscale surfaces being joined, and to arrest cracks. Such random voids would compromise bond integrity and electrical conductivity of interconnects being bonded. In example systems, a predesigned recess space or predesigned pattern of recesses placed in the bonding interface captures particles and gases, reducing the formation of random voids, thereby improving and protecting the bond as it forms. The recess space or pattern of recesses may be placed where particles collect on the bonding surface, through example methods of determining where mobilized particles move during bond wave propagation.

  • Publication number: 20220230791
    Abstract: A magnetic element includes at least one first air gap. A first portion of the first air gap is arranged between the first projection line and the second projection line. A second portion of the first air gap is beyond the region between the third projection line and the fourth projection line. Due to the air gap, the dielectric constant between the first end part of the winding and the magnetic leg and the dielectric constant between the second end part of the winding and the magnetic leg are reduced. Moreover, the electric field distribution of the first end part and the second end part will be more uniform, and the partial discharge extinction voltage will be increased. The volume and the cost of the magnetic element are both reduced. In addition, the equalizing rings are not required. Consequently, the fabricating process of the magnetic element is simplified.
