Abstract: A wave launcher may include a printed circuit board (PCB) that includes a pin that receives a radio frequency (RF) signal. The wave launcher may include a cylinder configured to be electrically coupled to the pin and define an opening. The cylinder may receive the RF signal from the pin, form a transition from coplanar to Goubau line structure with a plate, and generate the surface wave. The wave launcher may include an insulator configured to be physically positioned within the opening and between the cylinder and a power line. The insulator may mechanically isolate the cylinder from the power line and permit the cylinder to launch the surface wave on the power line. The wave launcher may include the plate electrically coupled to a pad and may provide a reference for the pin and the cylinder. The pin and the cylinder may be physically positioned proximate the plate.

Abstract: Methods and apparatus for one-time password detection and alert are disclosed. A disclosed example apparatus includes machine readable instructions, and at least one processor circuit to be programmed by the machine readable instructions to classify, with a trained machine-learning model, messages of a messaging platform of a computing device as one of a financial transaction or a non-financial transaction, and provide a warning based on a one-time password (OTP) message of the messages being classified as a financial transaction.
