Appl. No.:

17/392364

Inventors:

- Cary NC, US
Hoang Thanh Tran - Cary NC, US

International Classification:

H04W 4/021
H04W 8/20
G06Q 30/02

Abstract:

According to one embodiment, a network device includes an uplink port, a downlink port, a memory, and a processor. The processor is configured for providing a webserver; receiving a request from a mobile device of a user to establish a connection with the downlink port; establishing a first connection between the mobile device and the webserver via the downlink port; determining a media access control (MAC) address of the mobile device; receiving, from a server, user history information associated with the MAC address; and providing targeted information to the mobile device based on the user history information. The processor may be further configured for querying the server using the MAC address to obtain the user history information, collecting new user information and transmitting updated user history information to the server.

Abstract:

A conductive paste composition comprises (i) an inorganic powder comprising at least a conductive powder, (ii) at least one microgel polymer, and (iii) a solvent. The paste composition may be used in a process for manufacturing an electrical device comprising: preparing a substrate; applying the conductive paste onto the substrate in a preselected pattern;and heating the applied conductive paste to form a conductive structure that provides an electrode for connecting the device. The paste composition beneficially permits the formation of narrow, high aspect ratio features in the conductive structure.
