Abstract: Provided are a resource sharing method, device and system. The method includes: establishing, by a cloud desktop system based on a virtual desktop infrastructure (VDI), links with multiple terminals; and acquiring, by the cloud desktop system, resources of the multiple terminals through the links, and sharing the acquired resources to the multiple terminals.

Abstract: The present disclosure generally relates to the field of fire alarms. The teachings thereof may be embodied in a strobe notification appliance having: a boost circuit connected to an input voltage; an energy storage circuit charged by the boost circuit; a drive circuit generating a drive current; an LED circuit with at least one LED element; a first sampling circuit collecting an overall voltage drop of all the LED elements; and a control circuit configured to adjust the drive circuit to supply a working current during an alarming stage and supply a detection current during a detection stage. The detection current is lower than the working current and thereby light energy produced by the LED elements during the detection stage is lower than alarming light energy produced during the alarming stage. During the detection stage, the control circuit determines whether the LED circuit works normally based on the collected overall voltage drop.

Abstract: A visual notification device in a fire-fighting system may include an input end, a booster circuit, an energy storage element, at least one flash element, and a flash control circuit, for causing energy in the energy storage element to be applied to the at least one flash element to make it flash. At least one of the booster circuit, the at least one flash element, and the flash control circuit is designed such that a residual voltage across the energy storage element in each flash operation is greater than or equal to the input voltage. The visual notification device may enable the occurrence of a repetitive inrush current to be suppressed effectively without the addition of a current-limiting circuit.

Abstract: A movable ball-shape connector for a lighting fixture includes a movable rod, a spherical body, a fix cup, a press block, a spring, and an adjusting block. The spring is disposed between the spherical body and the adjusting block, to produce an elastic force acting upward. And that is used to produce the force to press the spherical body to stay between the movable rod and the fix cup, to fix the spherical body to a certain angle after rotation. Meanwhile, the adjusting block can be rotated, to make it move upward or downward, to adjust the force of the spring pressing against the spherical body, in achieving the objective of fixing the spherical body to a certain angle after rotation.

Abstract: The present invention provides a method for implementing an Unstructured Supplementary Service Data (USSD) service in a Code Division Multiple Access (CDMA) network, which is implemented based on a mobile intelligent network service and a flash message service. A Mobile Switching Center (MSC) triggers the mobile intelligent network service, a Service Control Point (SCP) determines an operation type code of the current step according to a user identification and a USSD access code and performs a corresponding operation, and at the same time constructs short message content associated with the operation type code of the current step, and transmits the short message content to a Mobile Station (MS) by way of the flash message. The present invention also correspondingly provides a system and device for implementing a USSD service in a CDMA network. By providing an operation prompt, the present invention realizes real-time message interaction, and reduces user's misoperation effectively.

Abstract: The present invention discloses a charging method and system for a prepaid service. The charging method comprises the following steps that: a VPN charging management module presets different VPN package charging levels in the prepaid service, receives a calling request from a user terminal, and determines whether there is at least one VPN valid user in a calling terminal and a called terminal and determines whether this calling belongs to the preset different VPN package charging levels; and a VPN charging module charges the calling terminal or the called terminal which is a VPN valid user for this calling according to the VPN package charging level to which the calling terminal or the called terminal belongs, and ends this calling if the amount of the user terminal account is insufficient.

Abstract: A film scanning method including the following steps is provided. Firstly, a film including an identification code and an image information area is provided, wherein the identification code is disposed on one side of the image information area along a first direction and has a first identification end and a second identification end along a second direction. Next, a location information of the identification code and a sequence information of the first identification end and the second identification end are checked and recorded. Lastly, the scanned image is adjusted along the first direction and the second direction respectively according to the location information and the sequence information. The invention provides the user with convenience in using a film scanning device without using additional elements.
