A mobile robot guest for interacting with a human resident performs a room-traversing search procedure prior to interacting with the resident, and may verbally query whether the resident being sought is present. Upon finding the resident, the mobile robot may facilitate a teleconferencing session with a remote third party, or interact with the resident in a number of ways. For example, the robot may carry on a dialogue with the resident, reinforce compliance with medication or other schedules, etc. In addition, the robot incorporates safety features for preventing collisions with the resident; and the robot may audibly announce and/or visibly indicate its presence in order to avoid becoming a dangerous obstacle. Furthermore, the mobile robot behaves in accordance with an integral privacy policy, such that any sensor recording or transmission must be approved by the resident.

An architecture and methodology for designing, deploying, and managing a distributed application onto a distributed computing system is described.

Architecture for distributed computing system and automated design, deployment, and management of distributed applications

A system, method, software and related functions are provided for managing activity in a radio frequency band that is shared, both in frequency and time, by signals of multiple types. An example of such a frequency band is an unlicensed frequency band. Radio frequency energy in the frequency band is captured at one or more devices and/or locations in a region where activity in the frequency band is happening. Signals occurring in the frequency band are detected by sampling part or the entire frequency band for time intervals. Signal pulse energy in the band is detected and is used to classify signals according to signal type. Using knowledge of the types of signals occurring in the frequency band and other spectrum activity related statistics (referred to as spectrum intelligence), actions can be taken in a device or network of devices to avoid interfering with other signals, and in general to optimize simultaneous use of the frequency band with the other signals. The spectrum intelligence may be used to suggest actions to a device user or network administrator, or to automatically invoke actions in a device or network of devices to maintain desirable performance.

The invention can enable monitoring of the display of content by a computer system. Moreover, the invention can enable monitoring of the displayed content to produce monitoring information from which conclusions may be deduced regarding the observation of the displayed content by an observer. The invention can also enable monitoring of the display at a content display site of content that is provided by a content provider site over a network to the content display site. Additionally, the invention can enable the expeditious provision of updated and/or tailored content over a network from a content provider site to a content display site so that the content provider's current and appropriately tailored content is always displayed at the content display site. Aspects of the invention related to transfer of content over a network are generally applicable to any type of network. However, it is contemplated that the invention can be particularly useful with a computer network, including private computer networks (e.g., America Online™) and public computer networks (e.g., the Internet). In particular, the invention can be advantageously used with computer networks or portions of computer networks over which video and/or audio content are transferred from one network site to another network site for observation, such as the World Wide Web portion of the Internet.

The disclosed embodiments include system and method for routing communications over a communications network. In one embodiment, a determination is made as to whether to establish a communication along a communication path based on network performance information. The disclosed embodiments provide several alternatives for establishing the communication and improving communications along the communication path in response to a determination that at least one network node along the communication path is impaired or congested.
