Abstract: Provided are a large-size diesel exhaust valve and a manufacturing method thereof, which relate to the technical field of manufacturing of large-size diesel exhaust valves for ships. The large-size diesel exhaust valve includes an exhaust valve disc portion made of a 3J40 alloy, and the large-size diesel exhaust valve has the following microstructure: there are ultra-fine grains with a grain size of 10 grade or more, ?-Cr lamellar phases are evenly distributed at grain boundaries of the ultra-fine grains, nickel-lean Cr—Al—Ce particle phases are evenly distributed in a matrix, a single lamella of the ?-Cr lamellar phases has a thickness of less than 140 nm, and the nickel-lean Cr—Al—Ce particle phases have a diameter of less than 10 ?m. The present application solves the technical problem of how to improve the comprehensive mechanical properties and the vibration-damping performance of a large-size diesel exhaust valve simultaneously.

Abstract: A wireless medical device, a central monitoring station, and a wireless medical monitoring system and method are disclosed. The system has a wireless medical device, a wireless access point, a wireless control unit and a central monitoring station, wherein the wireless medical device and the central monitoring station access a wireless network through the wireless access point and communicate with each other through the wireless network. The wireless medical device collects and processes at least one physiological parameter signal of a patient to obtain physiological data of the patient, and can also monitor network state information of the wireless access point to obtain first network state information; the wireless medical device sends the physiological data and the first network state information to the central monitoring station through the wireless network; and the central monitoring station at least displays the physiological data and stores the first network state information.

Abstract: A medical information display system and medical system are disclosed. The medical information display system includes: a communication interface, a storage device, a display device, and one or more processors. The processors are configured to execute program instructions stored in the storage device, thus allowing the processors to execute the following steps: acquiring via the communication interface vital signs information from a monitoring device and ultrasonic information generated by an ultrasonic device, controlling the storage device to store the vital signs information and the ultrasonic information according to timestamps; when a selection instruction with respect to one display area of multiple display areas is acquired, controlling the display device to display a detail interface of a corresponding target object; and when a review instruction with respect to a review hotkey is acquired, controlling the display device to display in the detail interface a review interface of the target object.

Abstract: A central station, a medical device, and a terminal device are disclosed. The central station is connected to at least two types of medical devices including at least one monitoring device. After receiving medical data sent by any medical device, the central station determines a device group that the medical device belongs to; and controls displaying the medical data in a display area corresponding to the device group. Medical devices in the same device group have an association relationship, and medical data of the medical devices with the association relationship are fused and displayed in the same display area.

Abstract: Methods, apparatus and systems for establishing voice communication are provided herein. An exemplary method can be implemented by an electronic device. A request initiated by a user can be received. The request can include one of a voice-communication request, a voice-communication-invitation request, a temporary-voice-communication request, a temporary-voice-communication-invitation request, an exclusive-voice-communication request, and an exclusive-voice-communication-invitation request. According to the request, a voice-room number can be obtained from a first server or a second server, without using third-party communication software. The method further includes starting a voice client and entering a voice room directly using the voice client, according to the voice-room number.

Abstract: Disclosed are a method and a device for pushing network information based on a location, which are used for solving the technical problem that an existing system is incapable of pushing network information based on a location. The present disclosure can effectively provide network information within a specific geographical region and drive a user to participate in network information activities, thereby improving the activity of the user to participate in network information interactions. Moreover, a recommendation engine based on a location facilitates the listening of more network information within the geographical region where a user is located, thereby forming a relationship chain with a good value, and further improving the activity of the user to participate in network information interactions.
