Abstract: In one embodiment, a method for monitoring events in a home network is provided. A node receives a subscription request from a control point, wherein the subscription request indicates an interest in delayable eventing. A change is detected in an event variable. It is then determined if the control point can receive an event sent from the node. If the control point cannot receive an event sent from the node, an event notification regarding the change in the event variable is stored such that the event notification can be retrieved when the control point can receive communications from the node.

Abstract: In one embodiment, a method for monitoring events in a home network is provided. The method includes receiving a subscription request from a control point, wherein the subscription request indicates one or more event variables to monitor for the control point. Then a change is detected in an event variable. Then, it is determined if the event variable has been indicated by the control point as an event variable to monitor for the control point. If so, then the control point is notified of the change in the event variable.

Abstract: In one embodiment, a method is performed at a control point (CP) in a network. An action is invoked to create a synchronization data structure on a media server that includes a content directory service (CDS) in the network, wherein the synchronization data structure includes a synchronization relationship describing a relationship between the CP and the CDS. Then an action is invoked to add synchronization pair information to one or more objects on the CDS. A change log is requested from the CDS. Then the change log is received from the CDS, wherein the change log contains information about changes to the one or more objects to which synchronization pair information for the CP was added.

Abstract: A method and system implementing a process for content synchronization that detects and prevents synchronization recursion in CDS transfer operations. A synchronization relationship is formed between the CDS containers in multiple devices. Then content synchronization processes are performed based on that relationship to avoid synchronization recursion.

Abstract: A method and system for providing QoS in a network using traffic management including traffic stream admission and traffic control, is provided. The traffic stream admission and control is achieved using parameterized QoS within a network. Such parameterized QoS enhances QoS service in the UPnP QoS architecture.

Abstract: A service discovery protocol is provided for use in personal area networks and other ad-hoc networking environments. The service discovery protocol is specifically designed to take into account the dynamic network configurations, bandwidth constraints as well as other characteristics of these types of networks. One of the key differentiators of the service discovery protocol is that it relies on a dynamically selected service directory device to manage the amount of information being distributed in the network.

Abstract: Low range limiting malfunctions of an engine coolant temperature (ECT) sensor are diagnosed by comparing a change in the sensed temperature during engine operation with a calibrated temperature change. If the change in sensed temperature fails to exceed the calibrated temperature change, and a diagnostic for detecting a stuck ECT signal is either inconclusive or passed, a low range limiting malfunction of the sensor is indicated. If the diagnostic for detecting a stuck ECT signal is failed, the low range limiting diagnostic concludes with no report even if the change in sensed temperature fails to exceed the calibrated temperature change.

Abstract: A discovery framework model includes policy information in the device/service discovery protocols. Service discovery protocols are enhanced by embedding policy information in the over all discovery framework. A method of performing policy-controlled device/service discovery includes modeling a device/service discovery protocol with a state machine either at a gateway or at discovery agents. Policies are used to control and propagate device/service discovery information. These policies are sets of rules that define conditions and attributes under which a certain action is permitted or denied.

Abstract: A control system and method to monitor an intake air temperature sensing circuit for an internal combustion engine is shown. The electronic controller is connected to the intake air temperature sensing circuit, coolant temperature sensor, and a plurality of other engine sensors. The controller determines whether the measured intake air temperature changes in response to a change in actual intake air temperature, based upon the engine operating conditions and the measured intake air temperature. The controller determines whether the measured intake air temperature is representative of actual intake air temperature, based upon the measured intake air temperature, the coolant temperature, and at least one engine operating condition. The invention is an element of an on-board diagnostic system, typically related to vehicle emissions.

Abstract: A remote computer access facility uses two dedicated computers outside the firewall. To ensure security the system makes use of biometrics features and a one-time password mechanism on top of secure socket layer (SSL) to authenticate a user. The system also provides three layers of security levels for transmission. The first layer establishes an SSL connection, the second layer periodically asks for a one-time password (OTP), and the third layer uses any kind of conventional encryption. The combination of the biometric, OTP and encryption key forms a strong password. The system also uses a mechanism for secure file accesses within the organization based on the security privileges assigned to various users. Based on the user's access privileges, the server side software module sends the requested file in an encrypted form along with the key to decrypt that file—this key is encrypted by the user's strong password.

Abstract: A method architecture for extending universal plug and play (UPnP) beyond a local area network is presented. This method includes a mobile device proxying agents. The mobile device proxying agents translate messages between UPnP and session initiation protocol (SIP) formats and sessions.

Abstract: One or more system components participate in a SIP-enabled service discovery protocol. Participation includes using SIP capability to publish, subscribe to, and/or notify of services using: (a) a service description formatted according to a predefined service discovery protocol; and/or (b) a service description query formatted according to the predefined service discovery protocol. The predefined service discovery protocol can be SLP. The system component can be a service providing device, a service subscribing device, and/or a network node. Service subscribing devices can use subscribe and notify components of a SIP event package to send service description queries and obtain service descriptions. Service providing devices can advertise service descriptions using the SIP publish method. Network nodes can propagate service advertisements downstream using the SIP publish method, and/or can inform subscribing devices of services using the notify component of the SIP event package.

The proxy also maintains personal information profiles for different kinds of devices based on presence and messaging services.

Abstract: The virtual instant messaging system adds instant messaging and presence capability to devices and appliances which are not natively designed for instant messaging. The virtual instant messaging system performs the physical communication handling and semantic translation issues to allow legacy devices to operate within the instant messaging paradigm. Virtual devices, representing real devices or information sources, may be constructed, on the fly as needed, or on a more permanent or persistent basis. Multiple virtual devices may be combined to compose or synthesize a new virtual device, affording capabilities not found in the real world devices or information sources themselves.

Abstract: Electronic reminders are created and managed using instant messages and/or multimedia messages. Reminders can be associated with future location or proximity events.

Abstract: An entertainment device is provided for adaptively tuning to a content signal. The entertainment device includes a receiver responsive to content signals provided to the entertainment device. A selected channel of the receiver provides an output signal to an output terminal of the automobile entertainment device. A data processor is operably linked to the receiver for receiving a signal index of the content signal. The data processor is responsive to a predetermined signal index for actuating the receiver to select the specific channel corresponding to the predetermined signal index. A memory stores the predetermined signal index in accordance with an operator preference. Thus, the predetermined signal index enables the entertainment device to adaptively adjust to an operator's preferred content.
