Abstract: The disclosure provides a method for preparing an electrode film layer on a surface of a solar cell substrate. The method includes: a) obtaining a metal electrode material melt by heating and melting a metal electrode material under a vacuum condition; b) bombarding the metal electrode material melt with an ion source at low energy, so that it is sputtered and deposited on the surface of the solar cell substrate to form the electrode film layer; in which the energy of low energy bombarding is 30 eV to 80 eV.

Abstract: An example method is provided and includes detecting, during a virtual meeting session, a plurality of events associated with each of a plurality of endpoints connected to the virtual meeting session. Each of the endpoints may be associated with a user identifier. The method also includes determining a status value for each of the plurality of endpoints based analyzing one or more of the plurality of events against a metric. The method also includes storing information related to the plurality of events. An output representative of at least one portion of the virtual meeting session is generated based on the stored information. The output identifies a classification of attentiveness associated with a user identifier for the at least one portion of the virtual meeting session.

Abstract: In an online conference between a plurality of client devices hosted by at least one server, a first client device receives at least two of an audio session including audio content associated with the online conference, a video session including video content associated with the online conference, and a content session including content associated with the online conference other than audio and video content. A handoff operation is facilitated between the first client device and a second client device such that the second client device receives at least one of the audio session, the video session and the content session from the online conference while the first client device continues to receive at least every other session from the online conference.

Abstract: In one embodiment, a method includes determining a first display position for each of a plurality of images and displaying the images at the corresponding first display position, receiving first plurality of taps, associating each of the first plurality of taps with a corresponding image, to produce a first tapping pattern, storing the first tapping pattern, which includes the first plurality of taps and the corresponding images in an associated relationship, determining a second display position for each of the images and displaying the images at the corresponding second display positions, receiving second plurality of taps, associating each of the second plurality of taps with a corresponding image, which are displayed at the second display positions, to produce a second tapping pattern, determining whether the second tapping pattern matches the first tapping pattern, and changing an access state of the electronic device in response to determining a match.

Abstract: A system includes an interface operable to detect a plurality of active audio streams in a plurality of multimedia streams, each multimedia stream associated with a particular user. The system further includes a processor operable to generate a text translation of each active audio stream and generate a script comprising the text translation of each active audio stream and an indication of the particular user associated with each active audio stream, the text translations being ordered according to times associated with the respective corresponding active audio stream.
