  • Patent number: 11961118
    Abstract: The present invention relates to methods and systems for targeting and retargeting individuals with advertisement spots during television broadcasting. The method and system enable an advertiser for identifying and categorizing a set of viewers or individuals for retargeting advertisement based on parameters such as, but not limited to, interests or preferences of the individuals, past purchases and interactions of the individuals with the advertiser. The method and system further enable the advertiser to segregate the plurality of individuals into subgroups on the basis of information such as, but not limited to, demography, psychographic and behavioral characteristics of the plurality of individuals. The method and system then enable the advertiser to define one or more advertisement spots and corresponding advertisements to be delivered to different sub groups of individuals based on the categorization.

  • Patent number: 11924916
    Abstract: A user equipment (UE) is configured to transmit, to a cellular carrier, a request to activate the UE with the cellular carrier. The UE is also configured to, in response to receiving an authentication request for authenticating a user of the UE, transmit, to the cellular carrier, information identifying another UE and authentication information for authenticating the user ; prompt the user, via a display of the UE, to provide, to an input system of the UE, verification information transmitted to the other UE; transmit, to the cellular carrier, the verification information; and in response to validation of the verification information by the cellular carrier, receive an embedded subscriber identity module (eSIM) subscription transferred from the other UE.

  • Patent number: 6472321
    Abstract: The present invention relates to chemical vapor deposition processes related to the manufacture of integrated circuit devices. In accordance with one embodiment of the present invention, a process for forming an electrical contact to a silicon substrate is provided wherein a semiconductor wafer is positioned in a reaction chamber wherein the semiconductor wafer includes an insulating layer disposed over a semiconductor substrate, and the insulating layer defines a contact opening therein. The contact opening defines insulating side wall regions herein. The insulating side walls extend from an upper surface region of the insulating layer to an exposed semiconductor region of the semiconductor substrate. A set of reactants are introduced into the reaction chamber, RF plasma is generated in the vicinity of the semiconductor wafer, and the temperature and pressure of the reaction chamber is regulated.

  • Patent number: 6376380
    Abstract: The invention includes methods of forming memory circuitry, including methods of forming memory circuitry comprising a buried bit line array of memory cells. In one implementation, a method of forming memory circuitry comprising a buried bit line array of memory cells includes, in a single planarizing step, planarizing storage node contact opening plugging material and bit line trench plugging material to insulating material to form bit lines and storage node contacts which are electrically isolated laterally from one another by the insulating material. In one implementation, a method of forming memory circuitry comprising a buried bit line array of memory cells, includes forming word lines over a semiconductor substrate. An insulating layer is formed over the substrate and over the word lines. Using a single photomasking step, bit line contact openings and capacitor storage node contact openings are patterned and formed into the insulating layer.
