Abstract: A metasurface includes a dielectric material, a ground plane on a back side of the dielectric material; and at least one conductive element on a top surface of the dielectric material, wherein the at least one conductive element includes at least one of a ground-backed dipole or a slot array.

Abstract: A system comprises a set of sensors on a first end of a vehicle having the first end and a second end, and a controller. The sensors are configured to generate corresponding sensor data based on a detected object along a direction of movement of the vehicle. The controller is configured to compare a time at which the first sensor detected the object with a time at which the second sensor detected the object to identify the first end or the second end as a leading end of the vehicle, and to calculate a position of the leading end of the vehicle based on the sensor data generated by one or more of the first sensor or the second sensor. The controller is also configured to generate a map of the plurality of objects based on the sensor data.

Abstract: A security server for dynamic verification of web content located on a platform in the cloud or in the edge which runs artificial intelligence (AI) algorithms including a collector receiving collection of user interactions from an adapted browser of a remote to simulate content of pages loaded on the device based on user interactions from an adapted browser located on the end-user device navigating on the web and for sampling the outcome of these interactions at irregular time intervals, this sample resulting a fixed image such as JPG or PNG, a data mining and artificial intelligence (AI) algorithm relying on image processing executed while sample interval to detect object or patterns on the displayed content, a heartbeat generator generates heartbeat at regular interval and transmits at a continuous interval to the end-user's device to indicate to the adapted browser of the device it may display the content.

Abstract: A system comprises a first sensor on a first end of a vehicle and an on-board controller coupled to the first sensor. The first sensor is configured to detect a radio frequency (RF) signature of a marker along a guideway. The first sensor is a radar detection device. The on-board controller is configured to determine a first position of the vehicle on the guideway or a first distance from the position of the vehicle to a stopping location along the guideway based on at least the RF signature received from the first sensor. The marker is a metasurface plate comprising a first diffused element, a first retroreflector element, a first absorbing element and a second diffused element between the first retroreflector element and the first absorbing element.

Abstract: A method and a device for reading out keys of a keyboard. The read-out is realised by randomly generating a scanning pattern comprising for each row and column a read-out value to be applied on the rows and columns. The scanning pattern is preferably changed after having been applied to the keys. After application of the randomly generated pattern, the verification routine is applied in order to identify the selected keys.
