Abstract: Techniques disclosed herein relate to automatic pan-tilt-zoom adjustment to improve vital sign acquisition. In various embodiments, a vital sign acquisition camera (176) operable to pan, tilt, and zoom (“PTZ”) may capture (402) an image of a patient (100). The image may be analyzed (404) to detect a depicted position of the patient within an image coordinate space of the image. A desired position of the patient within the image coordinate space of the image may determined (406), and a difference in the image coordinate space between the depicted position and the desired position may be calculated (408). The difference may then be mapped (410) from the image coordinate space to a PTZ space. One or more PTZ parameters of the vital sign acquisition camera may be altered (412) based on the mapping. After altering the one or more PTZ parameters, the vital sign acquisition camera may acquire (414) one or more vital signs from the patient.

Abstract: This application discloses a route processing method and a network device. The network device obtains a route prefix and autonomous system information associated with the obtained route prefix, where the associated autonomous system information includes to-be-verified autonomous system information. The network device verifies whether there is a match item in a route origin information base, where the match item includes the obtained route prefix and the to-be-verified autonomous system information; and determines, based on a verification result, whether to send the obtained route prefix. The network device verifies the autonomous system information associated with the to-be-sent route prefix before sending the route prefix. This reduces a possibility that the network device sends route information carrying incorrect autonomous system information, and reduces a possibility of causing an abnormal network flow direction.

Abstract: Disclosed techniques relate to identifying subjects in digital images. In some embodiments, intake digital images (404) are acquired (1002) that capture a first subject. A subset of the intake digital images is selected (1004) that depict multiple different views of the first subject's face. Based on the selected subset of intake digital images, first subject reference templates are generated and stored in a subject database (412). Later, a second subject is selected (1008) for identification within an area. Associated second subject reference templates are retrieved (1010) from the subject reference database. Digital image(s) (420) that depict the area are acquired (1012). Portion(s) of the digital image(s) that depict faces of subject(s) in the area are detected (1014) as detected face image(s). A given detected face image is compared (1016) to the second subject reference templates to identify the second subject (1018) in the digital image(s) that capture the area.

Abstract: A loop avoidance communications method, where a first provider edge (PE) device sends a first identifier to a second PE device through a first interface, the first PE device receives, through the first interface, a data packet from the second PE device including the first identifier. Then, the first PE device determines that a second interface associated with the first identifier is in a faulty state. In response to the determining that the second interface is in the faulty state, the first PE device avoids sending the data packet to the second PE device through the first interface, where the first PE device connects to a customer edge (CE) device using the second interface.

The processor may be configured to receive patient identification information (e.g., responsive to user input and/or supplemented by additional information such a photo of the patient), to determine whether the patient identification information identifies a recurring patient, and if so, to retrieve, from the source of previously-acquired ultrasound image data, previous ultrasound images associated with the recurring patient.

Abstract: In a method for managing a VPN, a routing device establishes a BMP session with a BMP server. The routing device allocates a VPN label associated with a VPN instance, wherein the VPN instance is used for communication between the routing device and another routing device. Then, the routing device sends, to the BMP server, a BMP message that carries the VPN label. Because the routing device sends the VPN label through the BMP message, the routing device does not need to establish a BGP peer relationship with the BMP server to send the VPN label.
