Abstract: An example optical-electrical apparatus includes an optical-to-electrical conversion circuit, an electrical signal processing circuit, an electrical signal interface circuit, and a status detection circuit. The optical-to-electrical conversion circuit is configured to convert an optical signal into an electrical signal. The electrical signal processing circuit is configured to output a first parameter of the optical signal based on the electrical signal, where the first parameter includes an optical polarization parameter. The status detection circuit is configured to obtain status information of the optical signal based on the first parameter, where the status information of the optical signal is output via the electrical signal interface circuit.

Abstract: A method includes: generating fault alarm information, and sending the fault alarm information through a serializer/deserializer (SerDes) bus. The fault alarm information indicates a fault that occurs in a first apparatus and/or a target communication link, and the target communication link is a link for communication between the first apparatus and a second apparatus.

Abstract: Presented is a wireless portable ultrasound acquisition system for dental imaging, having an ultrasound probe with a control switch connected through a cable to a portable ultrasound acquisition system that communicates wirelessly with a smart tablet or a phone display to display the ultrasound images. The system uses ultrasound signals to create images of alveolar bone structure and boundaries of enamel, dentin and gingiva of a patient.

Abstract: A method of sharing rights includes, using one or more processors, at the request of a first user, granting a right of the first user to a second user, contingent upon consent of the second user. Rights may be shared between any two parties on an individual basis. Corresponding systems, apparatuses and articles of manufacture are provided. Such methods, systems, apparatuses and articles of manufacture may be implemented using a client-server arrangement.
