Identify Related Entities On A Graph By Using Normalized Product Scores, N/A

Defensive Publications Series

A system and method for determining similarity of nodes on a graph using product similarity scores is described. A graph of nodes can be broken into a plurality of bi-partite graphs. For each bi-partite graph, the probability of getting from a first node to a second node through random walk can be determined. This probability can be multiplied with the probability of getting from a second node to a first node through a random walk to determine a product score for the two nodes. In some instances, the product score can be normalized using normalized conditional probabilities. These normalized probabilities …

Providing Activity To User Devices Based On User Location, D Shin

Defensive Publications Series

The present disclosure is directed to a framework using signals (e.g., ultra wideband) to enable accurate location-based activities (e.g., advertisements) based on a user’s location with relation to predetermined zones. For example, as a user moves from zone to zone with relation to the anchor device, the computing system can change the activity to reflect the user’s new zonal position (e.g., in real-time). In particular, a user can pass by a store with a display device containing an anchor device in the store window. As the user enters a first zone, the display device can display particular images of content. …

The support is especially advantageous in driverless/autonomous vehicles where the occupant seating in the passenger compartment is not constrained by the conventional vehicle driver/passenger seating positions. The translational and rotational support can, for example, account for rear facing, side facing, angled, and fully reclined seat/occupant positions.

Fast Logical Channel Disabling For User Equipment Including Embedded Subscriber Identification Module Cards, Edison Chen, Grace Chen

Defensive Publications Series

A user equipment (UE) can include multiple subscriber identity modules (SIMs) to enable connections to different telecommunications networks. For each connection to these different networks, the UE employs a corresponding channel profile to maintain and transmit over a logical channel. In order to rapidly change channel profiles and thus change connections from one network to another, the UE can employ a process with a reduced number of refreshflag commands, reducing the number of refreshes associated with changing connections. The UE thereby increases overall efficiency of the switching process and reduces the time required for such transitions.
