  • Patent number: 8830405
    Abstract: A DC/DC converter 10 has a high-side transistor QH as a switching element and a low-side transistor QL as a synchronous rectifier element. A first primary electrode D and secondary primary electrode S of the high-side transistor QH are connected to an input voltage VIN and an external terminal T1, respectively. A detection transistor QD is provided in a row with the high-side transistor QH, and the ON voltage of the high-side transistor QH when ON is output as detection voltage VQD from the detection transistor QD. The output detection voltage VQD is added to a feedback voltage VFB1 by an adder CB, and inputted to a comparator CMP1. The ON period of a one-shot pulse PS1 outputted from the comparator CMP1 is regulated so as to be in direct proportion to the sum of the detection voltage VQD and the feedback voltage VFB1.

  • Patent number: 8797378
    Abstract: In one method for communicating, a server can receive a first encoded media stream from a first sending device and a second encoded media stream from a second sending device from a plurality of co-located sending devices. The server can determine spatial relationships between the plurality of co-located sending devices and a plurality of co-located receiving devices. The server can select a first receiving device as a destination for the first encoded media stream and a second receiving device as a destination for the second encoded media stream based on the sending and receiving spatial relationships. The server can send the first encoded media stream to the first receiving device and the second encoded media stream to the second receiving device to be decoded and rendered. The spatial relationships can be based on physical locations for the plurality of co-located sending and receiving devices.

  • Patent number: 8786662
    Abstract: A method for initiating continuous succession of multiple real time interactive video sessions of a predetermined duration between two users among multiple users logged on to a server through a network. The method includes matching of a set of predetermined characteristics of a first user with a set of predetermined characteristics of other users, and identifying an appropriate second user for the first user to interact with. On identifying the second user, a real time interactive session of predetermined duration is initiated between the two users and the user accounts of the two users are debited by a predetermined amount of virtual currency. On identifying a swiping operation on the display screen in a predetermined manner, by any of the first and the second users, the method automatically terminates the current video session, and initiates a next video session for that user.

  • Patent number: 8692864
    Abstract: A system for a multi-point videoconference consisting of three or more simultaneously connected end-points in a one-to-many or a many-to-many conference via a dynamic-virtual-multi-point-control-unit. The system comprising of a dynamic control unit is created when the Audio and Video parameters with conference participants are input by the initiator. After the establishment of the conference the dynamic-control-unit may shift from end-point to end-point in the course of a conference without terminating the conference. The movement of the Composite table of parameters creates a virtual multipoint conference control unit first by selecting the best endpoint to host the dynamic control unit using the client device resources. The dynamic-control-unit uses a protocol to establish the connections between multipliable endpoints, including a requesting or initiating endpoint and two or more participating endpoints.
