Abstract: Disclosed are systems and methods for detecting a skimmer located proximate a card reader of a self-service terminal (SST). The systems and methods may include obtaining a baseline measurement for a plurality of sensors located proximate the card reader and activating a subset of the plurality of sensors. A signal may be received from each of the subset of the plurality of sensors that were activated. When the signal from each of the subset of the plurality of sensors deviate from the baseline measurement by a predetermined threshold, a determination may be made that the skimmer is proximate the card reader. In response to determining that the skimmer is located proximate the card reader, the self-service terminal may be disabled.

Abstract: A system for detecting mounting of a card skimmer at an automated teller machine receives detection data from sensors. The system converts the detection data from the time domain to the frequency domain using a wavelet transform to generate a wavelet matrix of coefficients. The system includes a convolutional neural network model to identify features in the wavelet matrix. The system generates a rain alert signal based on the identified features. The system includes a long short-term memory recurrent neural network model to determine a sequence of (i) an idle state, (ii) a hand approach state, and (iii) a card skimmer mounting state based on the detection data. The system generates a tamper alert signal based on the sequence determination.

Abstract: A first (second) electrical input port receives a first (second) drive signal. A first (second) transmission line is configured to propagate a first (second) electromagnetic wave over at least a portion of a first (second) optical waveguide arm of an MZI to apply an optical phase modulation. A drive signal interconnection structure is configured to provide a first electrical connection between the first electrical input port and an inner electrode shared by the transmission lines, and a second electrical connection between the second electrical input port and respective outer electrodes of the transmission lines; and is configured to preserve relative phase shifts between the drive signals. An impedance associated with a first electric field distribution between the inner electrode and a first of the outer electrodes is substantially equal to an impedance associated with a second electric field distribution between the inner electrode and a second of the outer electrodes.

Abstract: A magnetic field causing a difference of energy level between different spin states in the sample can be applied, a spin transition in the material can be triggered by exposing the sample to electromagnetic radiation of an energy level corresponding to the difference in energy level between the different spin states, a sensing surface of a superconducting element can be exposed to a magnetic field of the spins in the sample, the spin transition can cause, via kinetic inductance, a change in electromagnetic waves carried by the superconducting element which can be detected. A magnetic field component normal to the sensing surface, below a certain magnetic field threshold, can be applied to favor sensitivity.

Abstract: A display module (100) includes a light pipe (140), a liquid crystal display (LCD) module (130), a lens cover (110), and a gasket (120), which are mated together to form a sealed assembly. The LCD module (130) and gasket (120) are captured between the lens cover(110) and light pipe (140), such that the gasket (120) provides a seal between the lens cover (110) and the LCD module (130). Preferably, the gasket (120) has at least one integrally formed button (122) that protrudes through a buttonhole (112) on the lens cover (110) to provide for external actuation of a switch (152) within the display module assembly (100).
