Abstract: In a display driver circuit, a push-pull circuit is coupled to an internal circuit, a first external power terminal, a second external power terminal and a target node respectively, and can control the on-off of the first external power terminal, the second external power terminal and the target node in response to a target control signal transmitted by the internal circuit. The switching circuit is coupled to the target node and the I/O interface of the display driver circuit respectively, and can transmit an electric potential of the target node to the I/O interface of the display driver circuit, that is, a first power signal transmitted from the first external power terminal to the target node or a second power signal transmitted from the second external power terminal to the target node is further output to the I/O interface.

Abstract: A system and method for saving and restoring snapshots of a client device connected to a virtual desktop are disclosed. When a client device makes a request to capture the state of the virtual desktop, the request is sent to a server if the client device and virtual desktop are authorized according to a policy. The request may also specify that the virtual desktop's memory contents be captured. The server forms the snapshot and saves the snapshot in storage. When a client device makes a request to restore the virtual desktop, the client selects one of the saved snapshots and restores the virtual desktop, including its memory, when the client device and desktop are authorized, and the snapshot has not exceeded its allowed time in storage according to the policy.

Abstract: A system is described for scaling display content on a computing device based on user-to-device distance. A measurement is taken of the distance between the user and the device and a scaling setting is determined using a predefined rule based on the measured distance. The scaling setting is applied to scale content on the display based on the user-to-device distance by changing settings in the operating system or changing scaling in an application. Embodiments include virtual desktop/application and localized implementations.

Abstract: A method is provided to measure a relative frame rate of a remote desktop on a first computer and accessed by a second computer. The method includes playing a video timestamp on the remote desktop at the first computer where the video timestamp includes unique timestamps, screen capturing the remote desktop at the first computer and the second computer, determining a first frame rate at the second computer based on the screen capturing the remote desktop at the second computer, determining a second frame rate at the first computer based on the screen capturing the remote desktop at the first computer, and determining the relative frame rate as a ratio between the first and the second frame rates.

Abstract: A method is provided to measure an overall image quality score for a remote desktop on a first computer and accessed from a second computer. The method includes playing a video timestamp on the remote desktop at the first computer where the video timestamp includes unique timestamps, screen capturing first computer frames of the remote desktop at the first computer and second computer frames of the remote desktop at the second computer at the same time, determining a frame image quality score for each second computer frame by comparing the client screen to a corresponding baseline first computer frame, and determining the overall image quality score for the remote desktop from frame image quality scores of the second computer frames.

Abstract: This invention discloses an electrocatalyst for membrane electrode assembly, and its preparation method, as well as a fuel cell membrane electrode assembly. An electrocatalyst for fuel cell application, it is featured that the electrocatalyst is prepared by supporting precious metal (10-60 wt %) on a composite carrier which is prepared by depositing water-containing substance (0.3-10 wt %) on carbon material; Using the catalyst invented by this invention as anode catalyst, an fuel cell membrane electrode assembly with excellent non-humidification performance can be prepared by normal procedures. No need to construct a water retention layer, no need to add water retention material in proton exchange membrane, it avoids the possible problems caused by adding water attention material into proton exchange membrane or inserting a water retention layer. The approach suggested by this invention is a simple and effective approach to realize non-humidification membrane electrode assembly.
