Abstract: In an aspect, a user equipment (UE) receives a spoofing alert message from either a server or an internet-of-things (IOT) device that indicates whether a spoofed Global Navigation Satellite System (GNSS) condition is present. Based on determining that the spoofing alert message indicates that a spoofed GNSS condition is present, the UE determines, based on the spoofing alert message, a location of a spoofer broadcasting a spoofed GNSS signal, determines, based on the location of the spoofer and a current location of the UE, that the UE is within a receiving area of the spoofed GNSS signal, and determines a position of the UE without using the spoofed GNSS signal.

Abstract: Methods, systems, and devices for determining offsets for memory read operations are described. In response to a threshold quantity of pages failing initial reads but being successfully read using a same reference adjustment during re-reads, the offset responsible for the adjustment may be used as a first-applied offset for subsequent re-reads or a baseline offset for subsequent initial reads. After the initial reads begin using the reference adjustment, if a threshold quantity of pages fail initial reads, the offset used for the initial read may be adjusted to be the offset used to perform the successful re-reads. If an updated offset to use a baseline is not identified, the baseline offset may be cleared so the original reference may again be used without adjustment for initial reads.

Abstract: An approach is provided for dynamically identifying a danger zone for a predicted traffic accident and generating a warning about the accident. From a monitoring device at a first location, information about traffic conditions for vehicles at time T0 and at least one subsequent time T0+t is received. Based on speeds of the vehicles and a fixed distance from the first location, a response time is calculated. Within the response time, a dual artificial intelligence (AI) model using shallow and deep learners applied on historical accident data is employed. Based on the dual AI model and the traffic conditions, an accident involving vehicle(s) in the traffic is predicted to occur in a zone. A warning about the accident is generated and sent to device(s) in the vehicle(s). The warning is presented to driver(s) of the vehicle(s).
