Patent number: 7792924Abstract: Systems and methods are described for using a mobile phone to remotely control a computing device. In one implementation, a communication channel between the mobile phone and the computing device uses an overlay network, such as an instant messaging (IM) service, to exchange communication data packets. An exemplary system includes a flexible layered architecture—which allows tailoring the system for remote control of various applications using various network configurations. Based on the overlay protocol used, a transport protocol layer can provide helpful application programming interfaces (APIs). On top of the transport protocol layer, a remote control protocol defines a framework for packet exchange of extensible commands, customizable for remote control of diverse applications. Use of paired-key encryption, IM accounts, and buddy lists ensure that communications between mobile phone and remote computer are secure.Type: GrantFiled: November 30, 2005Date of Patent: September 7, 2010Assignee: Microsoft CorporationInventors: Yunxin Liu, Junfeng Zhou, Qian Zhang

Patent number: 7696740Abstract: A regulator circuit receives a power supply and provides a regulated power supply output suitable for integrated circuitry. It has a controllable current source circuit, a controller and a capacitor, such that an output of the controllable current source circuit can provide a lower frequency current part of the regulated power supply output, and the capacitor can supply a higher frequency current part of the regulated power supply output. The controllable current source circuit is controlled according to feedback from the regulated power supply output, and to restrict a rate of change of the output of the controllable current source circuit. The amount of EMI noise caused by high rate of change of current in power supply lines to the regulator circuit can be reduced. This can be done more efficiently or using a smaller capacitor than known arrangements.Type: GrantFiled: January 10, 2008Date of Patent: April 13, 2010Assignee: Semiconductor Components Industries, L.L.C.Inventors: Junfeng Zhou, Wim Dehaene

Patent number: 7333464Abstract: The present technique for automating service discovery and the set-up of a wireless network improves a user's experience when setting-up the wireless network and using one or more services. The technique includes automatic neighbor/service discovery using special beacons transmitted from wireless devices. Each special beacon identifies the wireless device (i.e., host) that transmitted the beacon along with the services provided by the device. For each special beacon that is received, a corresponding host name and the service provided by it are displayed in a graphical user interface. A user may select one or more of the host names and initiate a transmission of a network set-up and service request. The network set-up and service request identifies the selected host names and invites each selected host name to become a member of a wireless network. After the network has been set up, the service may be invoked automatically.Type: GrantFiled: February 1, 2006Date of Patent: February 19, 2008Assignee: Microsoft CorporationInventors: Fan Yang, Junfeng Zhou, Kun Tan, Qian Zhang
