Abstract: A peer-to-peer communication system that transmits application data from an application component on one network peer to an application component on another network peer. A programming interface is provided to the communication system to facilitate programming of applications that rely on peer-to-peer communications. The communication system uses messaging providers to which each peer may be connected for purposes other than communications between peer-to-peer application components, thereby reducing the resources a peer-to-peer application requires for communication and making the system advantageous for use in portable electronic devices. Additionally, the communication system uses addresses already assigned in each messaging provider, allowing peer-to-peer communication between peers that may otherwise have been non-addressable.

Abstract: A method for providing an interface to a Bluetooth compliant device can emulate a modem such that computer software programs can communicate through the Bluetooth compliant device in the same manner in which they would communicate through a standard modem to access a dial-up, wide area network. The method also supports an interface to a Bluetooth compliant device which can emulate a network socket such that computer software programs can communicate through the Bluetooth compliant device seemingly in the same manner in which they would communicate through a standard network interface card to access a local area network. The method also allows for the interface to a Bluetooth compliant device to be dependent on the nature of the Bluetooth compliant device.

Abstract: A device hosting framework provides hosting for software-implemented logical devices (including peripheral devices bridges) on a computer to expose their services as controlled devices per a peer networking protocol. The device hosting framework encapsulates discovery, description and control protocol operations of the peer networking protocol, which frees the developers of the hosted devices from having to individually implement the peer networking protocol in the hosted devices' software and need implement only the core functionality of the hosted device. The device hosting framework operates as a host supporting device interoperability via the peer networking protocol for multiple hosted devices.

Abstract: A method, apparatus, and computer program product provide applications and application developers with generic access from user mode to the L2CAP layer of Bluetooth by exposing the L2CAP layer to user mode via a socket interface. In particular, a kernel mode primary component and user mode helper component cooperate to expose a Winsock interface to user mode components, and to manage various Bluetooth-specific functions and operations, allowing a user mode user application to access Bluetooth functionality without providing Bluetooth-specific commands or actions, and without being required to use RFCOMM.

Abstract: Systems and methods for metering execution of code at runtime are described. According to one implementation, a call is received requesting execution of a protected service. In response, permission is requested for the execution. The request for permission is analyzed. A grant of permission is based on the analysis.

Abstract: A universal plug and play (UPnP) device makes itself known through a set of processes—discovery, description, control, eventing, and presentation. Following discovery of a UPnP device, an entity can learn more about the device and its capabilities by retrieving the device's description. The description includes vendor-specific manufacturer information like the model name and number, serial number, manufacturer name, URLs to vendor-specific Web sites, etc. The description also includes a list of any embedded devices or services, as well as URLs for control, eventing, and presentation. The description is written by a vendor, and is usually based on a device template produced by a UPnP forum working committee. The template is derived from a template language that is used to define elements to describe the device and any services supported by the device. The template language is written using an XML-based syntax that organizes and structures the elements.

Abstract: The invention makes possible remote control of devices in a piconet by remote users communicating over the Internet and the like by providing a proxy-bridge device. The proxy-bridge device is a bridge for sending packets to and from between an external device and a device in the piconet. Moreover, the proxy-bridge device also serves as a proxy for the external device to devices in the piconet and as a proxy for devices in the piconet accessing an external device. The proxy-bridge wireless device's protocol stack allows communications with the piconet devices within the piconet. In addition, the protocol stack allows an application to communicate with a remote device e.g., via the Internet Protocol. Thus, the proxy-bridge device, using two protocols, enables remote users discover the presence of a service offered by a device in a piconet as a logical embedded device within the proxy-bridge device and vice-versa.

Abstract: Controlled devices according to a device control model maintain a state table representative of their operational state. Devices providing a user control point interface for the controlled device obtain the state table of the controlled device, and may also obtain presentation data defining a remoted user interface of the controlled device and device control protocol data defining commands and data messaging protocol to effect control of the controlled device. These user control devices also subscribe to notifications of state table changes, which are distributed from the controlled device according to an eventing model. Accordingly, upon any change to the controlled device's operational state, the eventing model synchronizes the device's state as represented in the state table across all user control devices.
