Method for sharing input device, electronic devices, and system

This application discloses a method for sharing an input device, an electronic device, and a system, to support sharing of an input device among a plurality of electronic devices. After a first electronic device establishes a first connection to a second electronic device, a mouse pointer of the first electronic device may cross a boundary of a display interface and appears in a display interface of the second electronic device. When the mouse pointer is displayed on a display of the second electronic device, each time a user performs an input operation by using an input device, such as a mouse or a keyboard, of the first electronic device, the second electronic device may receive an input event from the first electronic device, and make a corresponding response to the input event. At the same time, the input event on the first electronic device side is shielded. According to this method, the user may perform an input operation on the second electronic device by using the input device of the first electronic device. The input operation of the user can be quickly and conveniently switched between different devices, and the input operation is more coherent. This improves input experience of the user.

Vm file management using file-level snapshots

VM file management includes detecting a user request to access to a virtual machine (VM) and searching a pre-defined list to determine whether the user requesting access is identified on the list. If so, a file-level snapshot is generated prior to enabling modification of a VM file by the user. The file-level snapshot includes a user attribute and is added as the top layer of a stack. The user attribute indicates a role of the user for whom the file-level snapshot is created. Each layer of the stack contains one or more other file-level snapshots. The VM file is written in the file's entirety to the snapshot in response to the user modifying the VM file. Based on the user attribute of each snapshot, a set of snapshots is selected from the stack, and the VM is modified by merging the VM files belonging to the set of snapshots selected.

Method and device for configuring cold redundancy of power source

The present disclosure provides a method and device for configuring cold redundancy of a power source. The method includes determining an efficient range and an inefficient range of an efficiency-load curve of a power supply unit (PSU), wherein the efficiency-load curve is acquired by testing the PSU in advance. If the PSU operates in the efficient range when voltage of the PSU is before a preconfigured power source configuration point, or if the PSU operates in the inefficient range when the voltage of the PSU is after the preconfigured power source configuration point, the method includes recalculating the preconfigured power source configuration point. If neither, then the method includes determining that the preconfigured power source configuration point is a power source configuration point, wherein the power source configuration point is a voltage value at which a standby PSU is switched to a power supply PSU when cold redundancy is configured.

Service delivery method, service execution method, pc and switch

The present invention provides a Computer Supported Telecommunications Applications (CSTA) protocol-based service delivery method, which includes: obtaining a switching function service that carries voice parameters; and sending the switching function service that carries voice parameters down to the switch side. The present invention also provides a CSTA-based service execution method, a Personal Computer (PC), a switch, and a voice service system. In the present invention, when the PC sends a switching function service to the switch, voice parameters can be carried in the switching function service. In this way, when the switch obtains the switching function service with voice parameters, the switch can play voice according to the voice parameters. Therefore, the present invention enables play of voice without modifying the existing service process, thus, simplifying the implementation.

Rectenna array for detecting power radiated pattern of microwave or millimeter-wave signals

A system is provided for measuring a power radiated pattern of an incident radio frequency (RF) signal indicating spatial distribution characteristics of a device under test (DUT). The system includes multiple antenna elements arranged in an array, where the antenna elements include antennas and diodes coupled to the antennas, respectively. Each antenna has a radar cross-section (RCS) that is too small for the antenna elements to operate in a reflect mode. Each diode is zero biased, such that the diodes receive the incident RF signal through the antennas to which the diodes are respectively coupled, and rectify the incident RF signal to DC voltages that are proportional to power of the incident RF signal, enabling the antenna elements to operate in a detect mode.

Rectenna-array zum erfassen einer strahlungsleistungscharakteristik von mikrowellen- oder millimeterwellensignalen

Es wird ein System zum Messen einer Strahlungsleistungscharakteristik eines einfallenden Hochfrequenz-(HF)-Signals, das Eigenschaften räumlicher Verteilung eines Prüflings (Device Under Test, DUT) angibt, geschaffen. Das System umfasst mehrere Antennenelemente, die in einem Array angeordnet sind, in dem die Antennenelemente Antennen und Dioden, die jeweils an die Antennen gekoppelt sind, umfassen. Jede Antenne weist einen Radarquerschnitt (Radar Cross-Section, RCS) auf, der zu klein für einen Reflexionsmodus-Betrieb der Mehrzahl von Antennenelementen ist. Jede Diode weist eine Nullvorspannung auf, sodass die Dioden das einfallende HF-Signal durch die Antennen, an die die Dioden jeweils gekoppelt sind, empfangen und das einfallende HF-Signal zu Gleichspannungen gleichrichten, die proportional zu der Leistung des einfallenden HF-Signals sind, wodurch die Antennenelemente in einem Erfassungsmodus betrieben werden können.
