Abstract: Disclosed are an electric wheel assembly applicable for a parallelly mounted dual-tire wheel, an axle, and a vehicle. The electric wheel assembly includes a wheel and support axle assembly, an internal-rotor hub motor, a planetary gear reducer and a brake system. A planetary carrier is connected to a hub. The hub is connected to a spoke and a rim. The wheel support axle passes through a rotor sleeve and is provided with a hub bearing to support the hub and a whole wheel. A sun gear disposed at an end of the rotor sleeve of the internal-rotor hub motor is a power input of the planetary gear speed reducer, and the planetary carrier is a power output. A planetary gear of the planetary gear reducer is a tower-shaped gear and realizes a relatively high transmission ratio under a condition that an axial length is relatively small.

Abstract: A method for diagnosing degradation of a fuel cell stack, including: S10, qualitatively determining a degradation type of the fuel cell stack according to a voltage-current curve of the fuel cell stack; S20, quantitatively measuring parameter values of each of individual cells of the fuel cell stack according to the degradation type, and quantitatively determining a degradation degree of each of the individual cells according to the parameter values; S30, determining a uniformity degradation degree among the individual cells of the fuel cell stack according to a non-uniformity degree of a voltage distribution of the individual cells. By qualitatively determining the degradation type of the fuel cell stack, the degradation condition of the entire fuel cell stack may be obtained.

Abstract: A client device provides to a user, in an application associated with a social-networking service provided by a server system, a link to a page associated with a third-party service provider. The third-party service provider is distinct from the social-networking service. In response to user selection of the link, the page is loaded within the application. The page includes script for calling one or more application programming interfaces (APIs) of the server system. The client device calls the one or more APIs to obtain information associated with the user from the server system. The client device displays the page within the application, and uses the information associated with the user to conduct a transaction with the third-party service provider through the page.

Abstract: Techniques are provided for enhancing a user's browsing experience, especially when the user is browsing third party websites via an application. For example, a user may use the application to browse web pages served from a third party website that is associated with a particular domain. While browsing the third party web pages, the user may save a URL corresponding to a third party web page that the user is currently viewing. In this manner, the user may store one or more URLs corresponding to web pages served from the third party website and/or served from multiple different third party domains browsed by the user. The saved URLs may be associated with the user. When the user browses web pages associated with a particular domain, a user selectable option may be provided that enables the user to see URLs stored for the user that are associated with that particular domain. The user may then select a particular displayed URL to access the web page corresponding to the selected URL.

Abstract: An application on a client device presents a content item to a user with a deep link that includes an application identifier that identifies an additional application on the client device and contains instructions that, when executed by the additional application, present a state of that additional application. When a user selects the deep link in the content item, the client device determines whether the additional application associated with the application identifier is installed on the client device and, if so, launches the additional application and communicates the instructions and a second deep link to the additional application. The second deep link includes an application identifier associated with the application and instructions describing a state of the application when the content item was presented.

Abstract: An application linking framework provides cross-platform mobile application-to-application linking, including allowing linking into particular states in an application via a deep link presented in another application. When a client device receives a content item including a deep link, the client device can also receive a tracking request for tracking user interaction with an application associated with the content item or deep link in the content item via an application linking tool. The tool can also provide suggestions to an application owner of actions to take based on the analytics and can track advertisement conversions across applications.
