Abstract: A computer-implemented method comprises receiving an image captured by a camera on an unmanned aerial vehicle (UAV). The image depicts an environment below the UAV. A feature mask associated with the image is generated via a machine learning model that is trained to identify and semantically label pixels representing the environment depicted in the image. One or more reference tiles associated with the environment are retrieved. The reference tiles are associated with particular geographic locations and specify semantically labeled pixels representing the geographic locations. The semantically labeled pixels of the feature mask are correlated with the semantically labeled pixels of at least one of the one or more reference tiles to determine the geographic location of the UAV in the environment.

Abstract: A method of multi-factor authentication is performed by an access control device. In response to detecting a voice command, the access control device sends a query to a location server for a current location of a user equipment (UE) included in a list of trusted UEs. The access control device may then receive an indication of the current location from the location server and in response thereto, the access control device may determine whether the current location of the UE is within a threshold distance of the access control device. If so, the access control device may generate an access signal that indicates that a user associated with the UE is authorized to access a protected resource.

Abstract: A method of multi-factor authentication is performed by an access control device. In response to detecting a beacon signal transmitted by a user equipment (UE) via a short-range radio access technology (RAT) the access control device sends a query to a location server for a current location of the UE. The access control device then determines whether the UE is within a threshold distance of the access control device and, if so, begins monitoring a signal strength of one or more beacon signals transmitted by the UE. If the signal strength of the one or more beacon signals exceeds a signal strength threshold, then the access control device may generate an access signal to indicate that a user associated with the UE is authorized to access a protected resource.

Abstract: A method of controlling user access to a protected area is performed by an access control device. In response to detecting a beacon signal transmitted by a user equipment (UE) via a short-range radio access technology (RAT) the access control device determines whether the UE is within the protected area or in an exterior area that is outside the protected area. In some aspects, the access control device determines whether the UE is within the protected area or in the exterior area based on the received beacon signal. In response to determining that the UE is in the exterior area, the access control device performs a multi-factor authentication procedure. If the access control device determines that the UE is within the protected area, the access control device is configured to deny access to the protected area.

Abstract: An integrated high-speed package comprising a package housing having a housing lip and connector having a center pin abutting along a bottom surface of the housing lip. For signal registration of a first substrate to the signal lead, the substrate is “floated” up to the housing lip, which provides an alignment reference to ensure that the top surface of the first substrate is aligned and in direct registration with the signal lead. In another embodiment, the center pin to substrate registration is provided at a top surface of a housing base. The housing base preferably comprises a first portion of a first height and a second portion of a second height. Accordingly, the housing base can accommodate substrates of different thickness while allowing a top surface of the first and a second substrate to be coplanar to facilitate signal registration there between.
