Disclosed are a passive triggered-power electronic tap-changer device and a contact device. The power electronic tap-changer device comprises: two taps, a main contact, two auxiliary contacts, two trigger contacts, an output terminal, two thyristors, and four voltage divider resistors, which can achieve the passive triggering of a power electronic switch by means of controlling the auxiliary contacts and the trigger contacts. Provided in the present invention is a contact device for the passive triggered-power electronic tap-changer, comprising: at least two stationary contacts, a main contact, two thyristor trigger contacts, two thyristor auxiliary contacts, and a drive shaft, wherein the main contact, the thyristor trigger contacts, and the thyristor auxiliary contacts are fixed to the drive shaft, the contact device can switch the power electronic switch to different stationary contacts by means of controlling the rotation of the drive shaft, and maintains the switching time sequence of passive triggering.

Passive triggered-power electronic tap-changer device and contact device

Triggering display of an application includes initially presenting a first interface, including an interface of a parent application, on a display screen and in response to receiving a gesture denoting an approximate closed region or a closed region, determining a non-full-screen display region corresponding to the gesture on the display screen. Based on the parent application being displayed as part of the first interface when receiving the gesture, identifying child application(s) of the parent application, the child application(s) being deemed relevant to the parent application, and displaying shortcut(s) of the child application(s) in the non-full-screen display region, and in response to a user selecting one of the shortcut(s), launching a child application corresponding to the selected shortcut and displaying an interface of the child application in the non-full-screen display region.

Triggering display of application

A method and system are provided for triggering display of an application. The method includes: in response to receiving a gesture denoting an approximate closed region or a closed region on a display screen, determining a non-full-screen display region corresponding to the gesture on the display screen; displaying shortcuts of at least one application in the non-full-screen display region; and in response to a user selecting one of the shortcuts, launching an application corresponding to the selected shortcut, and displaying an interface of the application in the non-full-screen display region.

A method to connect an application to an application service includes accessing code corresponding to an application to determine a reference to an application service, determining a service connection driver corresponding to the application service, invoking the service connection driver, and receiving connection information in response to the service connection driver establishing a service connection between the application and the application service. A corresponding computer program product and computer system are also disclosed herein.

Utilization of computing services

Controlling resource access, a first device responsive to a request for access to a resource, determines whether to grant the access to the resource, based on an identity of a requestor requesting the access to the resource. The resource is provided by a second device that is separate from the first device. The first device customizes an access token with an access constraint to control the access to the resource, the access token is generated responsive to the first device determining that, based on the identity of the requestor requesting the access to the resource, the access to the resource is granted.

Method and apparatus for controlling resources access

A circuit includes: a pull down circuit including a first PFET and a second PFET connected in series between a pad of a USB circuit and ground; and a pull up circuit including a first NFET and a second NFET connected in series between the pad and a supply voltage. The circuit includes: a third PFET connected to a gate of the first PFET and a gate of the second PFET; a third NFET connected to a gate of the first NFET and a gate of the second NFET; a fourth PFET connected to the first NFET and the second NFET; and a fourth NFET connected to the first PFET and the second PFET. A pad voltage has a nominal minimum and maximum. Each of the first PFET, the second PFET, the first NFET, and the second NFET has a nominal voltage less than the pad voltage nominal maximum.
