Abstract: The invention provides devices and methods for non-invasive monitoring and measuring of intraocular pressure (IOP) of a subject. Embodiments include a lens that is adapted to fit on the subject's eye, a microstructure disposed in or on the lens, the microstructure having at least one feature that exhibits a change in shape and/or geometry and/or position on the lens in response to a change in curvature of the lens. When the curvature of the lens changes in response to a change in IOP, a corresponding change in shape and/or geometry and/or position of the feature may be used to determine the change in IOP. The change in the feature is detectable in digital images of the lens taken with a mobile electronic device such as a smartphone.

Abstract: This application provides a path switching method and a related apparatus. In the path switching process, an ECMP table includes a first ECMP index of a first path group and a second ECMP index of a second path group; when all paths in the first path group have failed, a path group identifier corresponding to the first ECMP index may be changed from valid to invalid in the ECMP table, indicating that all paths in the first path group are unavailable. In this case, a path group identifier corresponding to the second ECMP index is valid, indicating that the second path group includes an available path, thereby completing switching between an active path and a standby path. In this process, only an identifier corresponding to the ECMP index needs to be updated, and therefore, the time consumed is relatively short, and the path switching delay can be effectively reduced.

Abstract: Certain aspects involve a machine-learning query system that uses a dual deep learning network to service queries and other requests. In one example, a machine-learning query system services a query received from a client computing system. A dual deep learning network included in the machine-learning query system matches an unstructured input data object, received from the client computing system, to an unstructured reference data object. The matching may include generating an input feature vector by an embedding subnetwork, based on the unstructured input data object. The matching may also include generating an output probability by a relationship subnetwork, based on the input feature vector and a relationship feature vector that is based on the unstructured reference data object. The machine-learning query system may transmit a responsive message to the client system.

Abstract: A test coverage rate improvement system for pins of tested circuit board and a method thereof are disclosed. In the system, partial pins of a circuit board connector in a tested circuit board are not electrically connected to the boundary scan chip, test pins of the test pin board are pressed with the partial pins by a fixture of a boundary scan interconnect testing workstation to electrically connect the test pins to the partial pins. A test access port controller receives a detection signal for detecting the partial pins, which are not electrically connected to the boundary scan chip, of the circuit board connector through the test pin board from the test adapter card, and determines whether conduction is formed based on the detection signal, thereby achieving the technical effect of improving a test coverage rate for the pins of the tested circuit board.

Abstract: A first data center interconnection (DCI) device in a first data center receives a first packet from a Border Gateway Protocol Ethernet virtual private network (BGP EVPN) neighbor, where the first packet includes routing information of a first forwarding instance of an access device in the first data center and an export route target of the first forwarding instance. The first DCI device obtains a second forwarding instance that corresponds to the first packet, where an import route target of the second forwarding instance matches the export route target of the first forwarding instance. The first DCI device generates a second packet that includes routing information of the second forwarding instance and an export route target of the second forwarding instance, which includes a DCI interworking route target. The first DCI device sends the second packet to a second DCI device in a second data center.
